Introduction To Magnetic Coupling Engineering Essay

Two music directors are denoted to as inductively coupled or magnetically coupled when they are constructed such that alteration in current flow through one wire induces a electromotive force across the terminals of the other wire through electromagnetic initiation. The measure of inductive matching between two music directors is measured by their common induction. The yoke among two wires can be increased by weaving them into spirals and puting them near together on a common axis, so the magnetic field of one spiral passes through the other spiral. The two spirals may be physically enclosed in a individual unit, as in the primary and secondary sides of a transformer, or may be separated. Yoke may be intended or unintended. Unintentional yoke is called cross-talk, and is a signifier of electromagnetic intervention. Inductive matching favours low frequence energy beginnings. High frequence energy beginnings by and large use capacitive yoke. An inductively coupled transponder involves an electronic informations transporting device, normally a individual micro chip, and a big spiral that maps as an aerial. Inductively conjugate transponders are about ever operated inactively.UsesDevicess that use inductive yoke comprises:TransformersA transformer is a device that handovers electrical energy from one circuit to another through inductively coupled conductors-the transformer ‘s spirals. A altering current in the first or primary twist creates a variable magnetic flux in the transformer ‘s nucleus, and therefore a variable magnetic field through the secondary twist. This altering magnetic field induces a fluctuating electromotive force ( EMF ) or â€Å" electromotive force † in the secondary twist. This consequence is called common initiation. If a burden is connected to the secondary, an electric current will flux in the secondary twist and electrical energy will be transferred from the primary circuit through the transformer to the burden. In an ideal transformer, the induced electromotive force in the secondary twist ( VS ) is in proportion to the primary electromotive force ( VP ) , and is given by the ratio of the figure of bends in the secondary ( NS ) to the figure of bends in the primary ( NP ) as follows: By appropriate choice of the ratio of bends, a transformer therefore allows an jumping current ( AC ) electromotive force to be â€Å" stepped up † by doing NS greater than NP, or â€Å" stepped down † by doing NS less than NP. In the huge bulk of transformers, the twists are coils lesion around a ferromagnetic nucleus, air-core transformers being a noteworthy exclusion. Transformers range in size from a thumbnail-sized yoke transformer hidden inside a phase mike to immense units weighing 100s of dozenss used to complect parts of power grids. All operate with the same basic rules, although the scope of designs is broad. While new engineerings have eliminated the demand for transformers in some electronic circuits, transformers are still found in about all electronic devices designed for family ( â€Å" brinies † ) electromotive force. Transformers are indispensable for high electromotive force power transmittal, which makes long distance transmittal economically practical.Electric motors and generatorsAn electric motor uses electrical energy to bring forth mechanical energy, really typically through the interaction of magnetic Fieldss and current-carrying music directors. The contrary procedure, bring forthing electrical energy from mechanical energy, is accomplished by a generator or dynamo. Grip motors used on vehicles frequently perform bot h undertakings. Many types of electric motors can be run as generators, and frailty versa. Electric motors are found in applications every bit diverse as industrial fans, blowers and pumps, machine tools, family contraptions, power tools, and disc thrusts. They may be powered by direct current ( for illustration a battery powered portable device or motor vehicle ) , or by jumping current from a cardinal electrical distribution grid. The smallest motors may be found in electric wrist watchs. Medium-size motors of extremely standardized dimensions and features provide convenient mechanical power for industrial utilizations. The really largest electric motors are used for propulsion of big ships, and for such intents as grapevine compressors, with evaluations in the 1000000s of Watts. Electric motors may be classified by the beginning of electric power, by their internal building, by their application, or by the type of gesture they give. The physical rule of production of mechanical force by the interactions of an electric current and a magnetic field was known every bit early as 1821. Electric motors of increasing efficiency were constructed throughout the nineteenth century, but commercial development of electric motors on a big graduated table required efficient electrical generators and electrical distribution webs. Some devices, such as magnetic solenoids and speaker units, although they generate some mechanical power, are non by and large referred to as electric motors, and are normally termed actuators and transducers, severally.Induction loop communicating systemsInduction cringle is a term used to depict an electromagnetic communication- and sensing system, trusting on the fact that a traveling magnet will bring on a electrical current in a nearby conducting wire. Induction cringles are used for transmittal and response of communicating signals, or for sensing of metal objects in metal sensors or vehicle presence indexs. A common modern usage for initiation cringles is to supply hearing aid to hearing assistance users.Artworks tabletA artworks tablet ( or digitising tablet, artworks pad, pulling tablet [ 1 ] ) is a computing machine input device that allows one to hand-draw images and artworks, similar to the manner one draws images with a pencil and paper. These tablets may besides be used to capture informations or handwritten signatures. A artworks tablet ( besides called pen tablet or digitiser ) consists of a level surface upon which the user may â€Å" pull † an image utilizing an affiliated stylus, a pen-like drawing setup. The image by and large does non look on the tablet itself but, instead, is displayed on the computing machine proctor. Some tablets nevertheless, come as a operation secondary computing machine screen that you can interact with straight utilizing the stylus. Some tablets are intended as a general replacing for a mouse as the primary pointing and pilotage device for desktop computing machines.Radio Frequency IdentificationRadio-frequency designation ( RFID ) is the usage of an object ( typically referred to as an RFID ticket ) applied to or incorporated into a merchandise, carnal, or individual for the intent of designation and tracking utilizing wireless moving ridges. Some tickets can be read from several metres off and beyond the line of sight of the reader. Radio-frequency designation comprises inquisitors ( besides known as readers ) , and tickets ( besides known as labels ) . Most RFID ticket contain at least two parts. One is an incorporate circuit for hive awaying and treating information, modulating and demodulating a radio-frequency ( RF ) signal, and other specialised maps. The 2nd is an aerial for having and conveying the signal.Inductive ModemsResonant energy transportationResonant energy transportation or resonating inductive yoke is the short-distance wireless transmittal of energy between two spirals that are extremely resonating at the same frequence. The equipment to make this is sometimes called a resonating transformer. While many transformers employ resonance, this type has a high Q and is about ever air-cored to avoid ‘iron ‘ losingss. [ commendation needed ] The spirals may be present in a individual piece of equipment or in separate pieces of equipment. Resonant transportation plants by doing a spiral pealing with an hovering current. This generates an oscillatory magnetic field. Because the spiral is extremely resonating any energy placed in the spiral dies off comparatively easy over really many rhythms ; but if a 2nd spiral is brought near to it, the spiral can pick up most of the energy before it is lost, even if it is some distance off. One of the applications of the resonating transformer is for the CCFL inverter. Another application of the resonating transformer is to match between phases of a superheterodyne receiving system, where the selectivity of the receiving system is provided by tuned transformers in the intermediate-frequency amplifiers. [ 1 ] Resonant transformers such as the Tesla spiral can bring forth really high electromotive forces without curving, and are able to supply much higher current than electrostatic high-potential coevals machines such as the Van de Graaff generator. [ Inductive charging merchandises charge batteries utilizing inductive yoke, such as eCoupled ; Torches, Cochlear Implants and many electric toothbrushes. Inductive charging uses the electromagnetic field to reassign energy between two objects. A bear downing station sends energy through inductive yoke to an electrical device, which shops the energy in the batteries. Because there is a little spread between the two spirals, inductive charging is one sort of short-distance radio energy transportation. The other sort of charging, direct wired contact ( besides known as conductive charging or direct yoke ) requires direct electrical contact between the batteries and the courser. Conductive charging is achieved by linking a device to a power beginning with plug-in wires, such as a moorage station, or by traveling batteries from a device to courser. Initiation coursers typically use an initiation spiral to make an alternating electromagnetic field from within a bear downing base station, and a 2nd initiation spiral in the portable device takes power from the electromagnetic field and converts it back into electrical current to bear down the battery. The two initiation spirals in propinquity combine to organize an electrical transformerInitiation cookers and initiation warming systemsAn initiation cooker uses a type of initiation warming for cooking. It is chiefly distinguished from other common signifiers of stovetop cookery by the fact that the heat is generated straight in the cookery vas, as opposed to being generated in the stovetop ( as by electrical spirals or firing gas ) and so transferred to the cooking vas. In an initiation stovetop, a spiral of Cu wire — an electromagnet — is placed underneath the cookery pot. An oscillatory current is applied to that spiral, which produces an oscillatory magnetic field. That magnetic field creates heat in the cooking vas over it, in two different ways. First, it induces a current in the electrically conductive pot, which produces Joule ( I2R ) heat. Second, it besides creates magnetic hysteresis losingss in the ferromagnetic pot. The first consequence dominates: hysteresis losingss typically account for less than 10 per centum of the entire heat generated. [ 1 ]Low frequence initiationLow frequence initiation is an unwanted signifier of inductive yoke, which can happen when a metallic grapevine is installed parallel to a high-potential power line. The grapevine, which is a music director, and is insulated from the Earth by its protective coating, can develop electromotive forces which are risky to personnel runing valves or otherwise rea ching the grapevine.Significance and Applications.Magnetic yokes are used to convey rotational and/or additive gesture without direct contact and Rotary yokes Linear yokes Hysteresis yokes Eddy current yokes Rotary yokes are chiefly used to extinguish the usage of seals in revolving and reciprocating machines, such as seal-less pumps and pistons.A Use of magnetic couplings improves the dependability and safety facets of such machines because seals are prone to deterioration over clip and cause leaks. Rotary magnetic couplings used in these applications are designed in two constellations – co-axial and face-to-face.A A In the co-axial constellation, the two halves of the coupling are mounted co-axially with each other and nested one within the other.A The outer member is typically connected to the motor and the interior member to the driven system, for illustration, the pump in a seal-less pump. A cup-shaped stationary member, mounted to the pump organic structure, resides between the driver and follower and separates the fluids on the pump side from the environment on the motor side.A Materials for the barrier cup and exposed surfaces of the follower are chosen to last uninterrupted contact with the fluids being pumped.A The thickness of the barrier is designed to defy any force per unit area derived function without important distortion. Face-to-face type yokes are used where axial length is at premium and some misalignment demands to be tolerated.A The two pancake-shaped parts consisting this type of coupling have magnets mounted on the close faces.A The separation barrier in this instance can be every bit simple as a level wall.A One facet of face-to-face type yokes is considerable attractive force between the two members. Linear and rotary magnetic yokes, and loanblends of the two, besides find application in vacuity engineering where place or gesture must be transmitted across a vacuity barrier.A An added consideration in these applications is stiffness of the yoke ; minimising the slowdown between driver and follower.A Linear magnetic yokes, following similar rules, allow precise control of robotics inside vacuity systems.A These couplings are used in the semiconducting material industry to place objects within a clean chamber. Elimination of seals and decrease of the figure of constituents inside the chamber improves taint control and enhances system dependability. In all the above instances, greater torque/force capacity is realized with stronger magnets, increased diameter and decreased radial gap.A An added consideration in these designs is the stiffness of the matching which consequences in more precise control.A Devices operating at elevated temperatures ( & gt ; 120 A °C ) typically employ Sm-Co magnets while others may utilize Nd-Fe-B or ceramic magnets. Hysteresis yokes are typically used where a torsion modification is needed, such as in the bottle cresting industry.A Eddy current couplings exhibit torsion that increases linearly with increasing revolutions per minute.A They are frequently employed in clasps and in couplings where utmost misalignment demands to be tolerated.A Hysteresis and eddy current rules may besides be used in the design of additive couplings. Magnetic Yokes are used in the industry to convey torsion through a spread. This spread is the distance between two members of the yoke. Between this spread, one may hold air, vacuity, fluids, centrifuge cups, or other similar points. There are two basic constellations that are utilized ; the Axial and Radial design. The Axial design requires that the two magnet systems face each other, similar to two battercakes confronting each other. As one member rotates, the other follows. The maximal torsion will be determined by many factors, such as air spread, figure of poles, stuffs selected, working temperature, etc. The Radial design requires that the magnet systems are homocentric to each other. As one member, typically the outer rotates andA the other follows. When choosing the barrier stuff between the matching members, see eddy current effects, since the flux lines of the magnetic yoke will cut the barrier material.A Conductive stuffs will get down to heat as the RPM is increased.A Conductive stuffs used as the barrier stuff will take opposition of the matching gesture, as some of the input work will turn into the eddy current losingss ( heat ) .A At higher RPM, over 600 RPM, this loss can be important. Typically, matching assemblies do non be as a standard â€Å" off the shelf † point. They have to be designed for each application, so manufactured. Depending on the complexness of your design, technology charges may use. If you are able to utilize a constellation that is near to something that we already have designed, and you are non concerned about â€Å" optimising † the constellation, engineering/design charges will non use. Yokes may be hermetically sealed so that they may work in rough environments, such as chemical applications.A Applications of magnetic yokes include atomic environments, chemically risky environments, high temperature environments, oil boring applications ( downhole ) , vacuity applications, andA quiver isolation applications. Industries that have benefited from magnetic yokes include aerospace, medical, chemical, pharmaceutical, nutrient, biotechnology, industrial ovens, compressors, metering, A A and fluid mechanicss, because magnetic yokes are the lone device that can convey contact free torsion.Magnetically-Coupled CircuitsA current i1 at L1 produces opencircuit electromotive force v2 at L2. A current i2 at L2 produces an unfastened circuit electromotive force v1 at L1. Current come ining the flecked terminus of one spiral produces a electromotive force that is sensed positively at the flecked terminus of the 2nd spiral. Current come ining the undotted terminus of one spiral produces a electromotive force that is sensed positively at the undotted terminus of the 2nd spiral.

Catcher in They Rey – Holdens Contradictory Views of the World

With close reference to pages 183-186 analyse Salinger’s use of language and structure, exploring Holden’s contradictory view of the world. On Page 183 Holden says ‘you could tell the two hot- shots I was with weren’t enjoying it too much. They stayed close as hell to me, and the one that didn’t talk at all practically was holding onto my sleeve’. Holden calls them ‘hot shots’ because they acted phony by bunking school and then lying about there being no school. (P182). Throughout the novel, Holden seems to have a problem with the whole idea of ‘phoniness’, yet at times, he himself acts phony.Holden considers movies to be extremely phony and criticises his brother because he moved to Hollywood. Holden emphasises his hatred for Hollywood and movies throughout the novel. Holden states his problem with phonies on page 184 when he says ‘I’d have this rule that nobody could do anything phony when they visited me. If anybody tried to do anything phony, they couldn’t stay’. He constantly demonstrates the idea that if people are ‘phony’ it’s a bad thing. We see this on pages 72/73 when he is talking about Ernie.He says that Ernie ‘is a terrific snob and he won’t hardly even talk to you unless you’re a big shot or a celebrity or something’. In this sentence, Holden implies that just because Ernie is good at playing the piano he thinks he can treat people badly, as if he is better than them. This seems to be Holden’s main dislike about ‘phoniness’, the fact that people act ‘phony’ because they think they are better than you. This is also shown on page 23 when Holden says that stradlater fixed himself up all the time because he was ‘madly in love with himself.He thought he was the handsomest guy in the whole of West Hemisphere’. He criticises Stradlater’s love for himself because h e sees this as an act of ‘phoniness’. While criticising people due to their ‘phoniness’ throughout the novel, Holden himself acts ‘phony’ on multiple occasions. On pages 48-52, when talking to Ernest Morrow’s mother, he pretends to be a completely different person to himself. He makes up a whole false persona in order to look better in front of Ernest’s mother. His false persona has a different name, and likes Ernest, even though Holden himself doesn’t have a high opinion of him.If somebody else were to do the same thing in front of Holden, he would undoubtedly call them ‘phony’. In chapter 17, when Holden goes on a date with Sally Hayes, he speaks just as posh as Sally does. This is shown when he says ‘swell to see you too’. Again, Holden is putting on a false persona in order for Sally to like him more. Throughout this whole chapter, Holden constantly criticises Sally on the way she speaks and ac ts, yet speaks and acts just like she does. By doing this, Holden is contradicting himself.He doesn’t seem to realise that he is acting just as ‘phony’ ads Sally is. Holden seems to act this way in front of most girls. I think he does this because he sees other guys acting the same way with girls and he naturally copies them because he doesn’t know how else to act. As a result, he contradicts himself often, but he just doesn’t realise this. On page 183, Holden states that the tomb was ‘so nice and peaceful’, yet he goes on to say that ‘you can’t find a place that’s nice and peaceful because there isn’t any’.Again, Holden is contradicting himself, but in a different way. He always seems to radically change his views based on little things. On page 184, he talks about his ideal future living in a cabin away from the world. When talking about how his family could visit him he says that he would let D. B. c ome and visit him for a while if he wanted ‘a nice, quiet place for his writing. ‘ Again he is contradicting himself because he is now saying that there is a place which is nice and peaceful, even though he previously stated that there isn't any.This is a clear example of Holden's unstable state of mind, because he doesn't remember what he previously says and he doesn't seem to have any set views as he is always contradicting himself. Loneliness is a key theme in the novel, and it is represented through Holden's contradictions. On page 184, when talking about his ideal future living alone in a cabin, he says, ‘I'd ask them all to visit me sometime if they wanted to, but I wouldn't insist or anything. ‘ This basically shows Holden's desperation for any type of relationship.Although he wants his family to visit him and keep him company, he doesn't want to admit it and therefore acts like he would invite them round as a favour to them, when really, it would make him feel better. On page 186, Phoebe is angry at Holden and Holden gets upset and feels guilty. this shows that he actually cares for Phoebe, even though he would never admit it. He shows this often throughout the novel when he talks highly about her. This idea is also shown on pages 122-123. Holden is so desperate for company that he just contacts anyone he could think of in order to have company.Even though he criticises these people based on their ‘phoniness', he still wants their company. This reoccurs on page 134. Holden spends all that time criticising Luce, yet ends up practically begging him to stay with him because he is lonely. He even admits his loneliness to Luce . ‘I'm lonesome as hell, no kidding'. This happens a lot during the novel. In chapter 10, Holden meets three girls, who he refers to as ‘pretty ugly' and ‘the three witches'. He spends the majority of the chapter pretending to like them in order to have company, even though he constantly criticises them to us.He constantly complains to us about things that they do, yet at the end of the chapter on page 67 when they say they had to leave, he says that he ‘tried to get them to stick around for a while'. This scene links together the last two points that I mentioned. Holden doesn't actually like the girls, yet he pretends he does so that he can have company. He also creates this false persona that is interested in the three girls. In order to do this, he had to use techniques that he has learnt from other people, even though he describes these other people as ‘phony'.Because he so socially unable, he takes techniques from others. What he doesn't realise is that by using these techniques, he himself is being a ‘phony'. You could say that deep down he knows that he does this a lot, yet he doesn't want to admit it to himself. In conclusion I think that Holden is highly contradictory about everything due to his troubled and confused state of mind. I thin k this is caused by the changes they are taking place in his life, such as getting kicked out of schools a lot and not understanding sexual relationships/feelings.

Impact of Economic Factors on Engagement with Pro-Environmental Measures

THE ENVIRONMENT Introduction: On most occasions, conservationist, and authorities bureaus tell us on the benefits of conserving the environment. This is because the universe is witnessing a series of environmental devastations, which range from devastation of woods, pollution of rivers, lakes and air. People argue that it is of import to continue the environment because they play a large function in prolonging the lives of persons. For illustrations, trees help in the formation of rainfall, which is an indispensable demand for agribusiness to last. Forests are natural home grounds of animate beings, and on this footing, destructing woods, will intend the devastation of wild animate beings. This in bend will interrupt the environmental eco-system ( Brooks, 2010 ) . Despite the importance of conserving the environment, most people still prosecute in its devastation. The grounds advanced for their engagement in destructing the environment are, poorness, population growing, and hunt of income. This paper identifies the grounds as to why people still prosecute in the devastation of the environment, despite the of import function that the environment plays in our society. Search for beginnings of income/ gross: Search for beginnings of gross and income is one of the major factors that lead to the devastation of the environment. Take for illustration oil geographic expedition and excavation is a factor that makes people to destruct the environment ( Tisdell, 2005 ) . Oil is an of import natural resource that all most all the economic systems of the universe demand. Oil is needed to drive the transit industry, which is indispensable for the growing of a country’s economic system ( Leydesdorff, 2007 ) . Oil plays a large function in using 1000000s of people all over the universe, and states such as Saudi-Arabia, Qatar, Libya, etc depend on oil production to prolong their economic systems. This is because oil is the major beginning of foreign gross for these states ( Tachibana, 2000 ) . It is of import to denote that oil geographic expedition and excavation play a great function in the devastation of the environment. Oil has the capableness of destructing the lives of animate beings, and human existences. Take for case the 2010 Gulf of Mexico oil spill which was responsible for leaking about 60,000 barrels of oil into the ocean ( Harper and Fletcher, 2011 ) . This had an effecting of killing sea animate beings, which included mahimahis, sea polo-necks, giants, etc. This oil spill was chiefly caused because of oil geographic expedition by BP Oil Company. The ground of these geographic expeditions was to mine oil, for commercial intents. Petroleum companies are besides accused of dumping toxic oil wastes on nearby rivers and Waterss. This has a cause of fouling the environment, and destructing the lives of Marine animate beings populating in these H2O systems ( Imanaka, 1997 ) . Petroleum companies are commercial companies, whose chief purpose is to sale oil merchandises for intents of doing net incomes, and grosss. Income net incomes and gross is non merely restricted to oil geographic expedition, but besides to the devastation of woods, and killing of wild animate beings. For illustration, people cut down trees for intents of acquiring wood. Wood is used to do lumber, a resource that is used to fabricate chairs, and edifice of houses ( Colson, 2011 ) . These are for commercial intents. The violent death of wild animate beings is besides carried out for intents of doing gaining an income, and due to poverty. For illustration, poachers normally kill elephants and rhinos for their ivories, and horns. Elephant Ivories are ever sold in Asia, and are used as beauty merchandises, and for intents of doing medical specialty. The same happens to the horns that poachers get from rhinos. Population Growth: Population growing is besides another factor that deters the preservation of the environment ( Newing, 2010 ) . Because of population growing, world has been forced to look for other topographic points of abode ( Likar, 2011 ) . This will do them to unclutter and destruct woods, as a consequence taking to the devastation of trees, and break of the eco-system. As celebrated earlier, woods are home grounds of wild animate beings, and birds. Destroying woods will take to the decease of some of these animate beings, because they may non happen other home grounds. The devastation of woods is non the lone negative environmental harm that population growing causes. Due to the high figure of people, there is the overconsumption of natural resources such as H2O, oil, nutrient, and even land ( Imanaka, 1997 ) . This consequences to doing these resources scarce. Scarcity of these environmental resources might take to unhealthy competition amongst people, in order to entree the resources under consideration. Peoples besides emit waste merchandises, because of their ingestion activities. This includes H2O, and air pollutants, toxic waste stuff, extra foods, and green house gases. Waste substances such as untreated sewerage may take to the devastation of an individual’s wellness. Other waste merchandises, such as inordinate N have an impact of doing the blooming of algals, in H2O supplies. This will take to the depletion of O, taking to the decease of marine animate beings such as fish ( Calhoun, 2005 ) . To protect the environment by restricting the growing of the environment, states such as China have adopted the one kid policy. This is whereby all twosomes are forced to bear to give birth to merely one kid. India besides has such sort of a policy, and the chief purpose of presenting these types of policy is to cut down the population growing of persons(Environmental issues. 2010 ). There has besides been some unreal method of commanding population growing, and this includes the usage of household planning methods ( Chancellor, 2009 ) . As a method of commanding the population growing in their states, authorities normally promote the usage of household planning methods. Poverty: Poverty is besides another factor that makes people to destruct the environment. In most states of the universe, specifically in the development states, there is the devastation of croping lands, dirt and woods because of over graze. These methods are ever efficient in commanding the population of a province, and therefore protecting an environment. As the growing rate of poorness additions, people destroy the environment faster, and more rapidly. The people over use the environment, such as dirt, land and woods, because they do non hold other beginnings of income, except by utilizing the natural resources under their range ( Harper and Fletcher, 2011 ) . It is of import to denote that because of poorness, the hapless will utilize the natural resources under their range for intents of fulfilling their footing demands. This will include fetching and utilizing firewood to cook, overdriving land for agricultural production, and usage of wild workss and H2O for medical specialty ( Canava ri and Food, 2002 ) . Poor people lack good and better instruction which can assist them to procure good occupations and beginnings of income. On this footing, they lack the quality of life that can do them to utilize electricity for cookery intents, or for other sectors of their domestic life ( Michna, 2010 ) . Electricity can assist in restricting the firewood concern that these people engage in. This is because persons will non depend on firewood as their beginnings of energy. To undertake poorness, the assorted authoritiess need to ordain policies aimed making employment, and bettering the instruction system of a province. The authorities can promote the usage of their trade accomplishments in assisting the hapless to gain income ( Hambler, 2004 ) . But this should happen in a mode that is suited for the saving of the environment. To cover with poorness, policies from the authorities are non sufficient. The authorities needs to spouse with private establishments and non-governmental organisations for intents of promoting them to educate people on the assorted ways of undertaking poorness ( Takeuchi, 2006 ) . This will be effectual because non-governmental organisations usually have an entree to the people, because of their grass root connexions. The hapless can be educated on the importance of continuing the environment ( Graetz, 2011 ) . This will do the hapless to hold knowledge on the benefits of the environment, doing them to utilize the natural resources under their range in a sustainable method. Decision: In decision, poorness, hunt for income, and population growing are some of the factors that encourage people non to prosecute in pro-environmental steps. As discussed in this paper, due to poverty, people will seek to unsuitably utilize the environment for intents of prolonging themselves. This includes film editing of woods for intents of acquiring lumber, over-using the land resource under their ownership, for agricultural intents, and over-grazing. However, with the usage of appropriate authorities policy, it is possible to cut down the degrees of poorness within a province. Search for income is another ground for depletion of the environment, and this usually takes the signifier of geographic expeditions and excavation. This is a really hard issue to work out, because authoritiess are ever in a quandary. That is, whether to halt the geographic expeditions or whether to go on with the geographic expeditions. Stoping the geographic expedition will intend losing a beginning of gross, while go oning with the geographic expedition will intend destructing the environment. Population growing on the other manus is easy to work out. All that a province demands to make is to make a policy restricting the figure of kids an person can give birth to. Mentions: Brooks, J. S.

Mexican Immigration in Los Angles 1990's Essay Example | Topics and Well Written Essays - 2000 words

Mexican Immigration in Los Angles 1990's - Essay Example In this new political and economic context, the 1982 and 1994 financial crises have contributed to a redefinition of the relations between unions and the state, especially with regard to labour market deregulation, but also regarding capital-labour relations (Zapata 6-10; Delgado 1-19). The direct effect of the new economic and labour context has been to make employment more precarious, with a general reduction in wages. This has been going on for nearly 20 years (Cortes 12-19). Income levels, already low in 1980, declined even further in the next few years. For example, the minimum wage shows an uninterrupted tendency to fall steadily over the last 20 years, and by 1998 it was worth only 31 per cent of its 1980 value. Average working incomes have also been badly hit and have continued to go down during this period. In the first half of the 1990s there was some improvement in average incomes, but not enough to restore wages to the values they had in the early 1980s. The crisis of December 1994 reduced salaries again, and this state of affairs has continued pretty much up until now (2002). The current value of average working incomes is still about 25 per cent less than it was at the start of the 1980s (see Figure 1). In addition, the number of people earning less than the minimum wage has increased, from 27.7 per cent of the working population in 1990 to 32.5 per cent in 1995 and 37.5 per cent in 1997. The proportion of those receiving between twice and five times the minimum wage has remained stable over the decade. Those who earn more than five minimum wages are in the curious position of having increased in number in 1995 only to go back to representing the same proportion of the workforce as in 1990 (see Table 1). In spite of this, the most important fact to emerge from the figures is that for the entire 1990s a third of the working population earned less than the minimum wage established by law, which is itself very meagre and insufficient to cover even basic needs. Furthermore, an additional 30 per cent of the working population earned between 1 and 2 minimum wages. This means that two-thirds of the workforce have been exposed to a precarious and vulnerable situation in which the movement of their wages has been, in fact, downwards. The persistence of this pattern of income inequity and insecurity for more than 20 years has made migration a real alternative for many. International migration (and remittances) has become a more attractive option than working in new industrial zones or in cities in Mexico, although job opportunities in urban areas are far superior to the limited chances in the Mexican countryside. As Figure 2 shows, the average amount sent back in remittances to Mexico by each migrant worker from 1995 onwards is 2.4 times the official minimum wage, which is two-thirds of the average working income in Mexico. In other words, migrant workers were able to bring to the family income as much money as

Advanced Business Finance and Advanced Financial Management Essay

Advanced Business Finance and Advanced Financial Management - Essay Example Ciana, (2011, p. 34) argues that when investor points at reliable quotation in a potential market, the entire data on the key traits that shall promote success in such an investment usually go unnoticed as price-to-earnings ratio, volume and size of the market, or even ex-share date targeted as priority. Previous studies on fundamental and technical analysis framework has created sizeable prove on their respective capabilities to discuss the arena of stock prices or to predict future variation of the share value. Despite this achievement, the literature has been silent on developing a reliable approach of integrating both technical and fundamental analysis methods in determining equity valuation as well as reaching to an investment decision. The current study utilizes fused fundamental framework whereby objective analysis of the share value is integrated with the technical analysis of the past returns and value in the stock market. More specifically, the report focused on the share values in banks, supermarket, telecommunication companies and RandGold Resource limited. The technical information in UK stocks has been utilized frequently by the investors to make decision pertaining which industry they should invest in. Generally, the technical information focuses on the shares’ price over a short term as well as the returns attained from sale volume information. Even when the stock price strays, the arbitrager can end up acquiring excess simultaneous returns in the market. A notable business research based on technical information in the UK stock price is the momentum investment approach (Konecny, 2013, p. 175). Along with the increase of the abnormal phenomena, attempted exploration on feasibilities of UK stock market anomalies stretch out to shaping investment behavior on account of the financial capacity. For instance, the investor applies heuristics to cement subjective marks and regarded as crucial decision criteria to attain abnormal

BIOL 232 Human Physiology - assignment Essay Example | Topics and Well Written Essays - 1000 words

BIOL 232 Human Physiology - assignment - Essay Example The ACE inhibitor corrects this problem by inhibiting angiogenesis-converting enzymes, which in turn lower the activity level of the renin-angiotensin-aldosterone system (RAAS). This allows renin from the juxtaglomerular apparatus to produce angiotensin, which tells the adrenal glands to produce aldosterone. The ACEI tells the body to do this, thus keeping the blood pressure under control. If the woman was to start taking this, and blood and urine samples were taken, I would see an abnormal level of both sodium and potassium. The woman’s sodium levels would be higher, due to the fact that by using angiotensin produced by the body via the ACEI, it will create more aldosterone, which in turn will cause her kidney tubules to retain more sodium ions. For the same reason, her potassium levels would be lower, as the aldosterone causes kidney tubules to excrete potassium. The ACEI will affect the woman’s cardiac cycle by constricting her arterioles. This will cause arterial bl ood pressure to rise, while decreasing the blood flow. Regardless of the dosage, the woman will have an increase in myocardial capillarization. The glomular filtration rate is the same, which in turn increases her capillary filtration, in spite of lowered kidney blood flow. ... Explain in detail how this weapon would affect the following: a) heart rate, b) kidney function, c) absorption of nutrients following digestion. This weapon would affect the Na/K pump’s action by raising the person’s heart rate, as the Na/K pump’s action would reduce. In addition, it would increase the person’s atrial fibrillation, chances of heart failure, and atrial fluttering. The Na/K pump would no longer be able to assist with myocardial contractility, increasing stroke possibility, decreased tissue perfusion, lowered hemodynamics and worsening of the ventricular function curve. The weapon would affect the kidney function by decreasing renal blood flow, thus raising the glomular filtration rate, which decreases capillary filtration. This in turn will reduce to amount of aldosterone secreted by the body, decreasing sodium absorption and increasing potassium ions within the body. This is because the aldosterone has been reduced; therefore, the kidneys d o not secrete enough potassium. This lowers blood volume and lowers blood pressure. Finally, the weapon would affect nutrient absorption in the rumen of the small and large intestines due to a decrease of cellular sodium levels due to the reduced activity of the Na/K pump. This lowers sodium instability in the gastrointestinal system, lowering the body’s ability to absorb nutrients properly. Question 3. Organophosphates are chemical agents that bind to and inhibit acetylcholine esterase. Explain the effects of exposure to high levels of organophosphates on the somatic nervous system and the parasympathetic division of the autonomic nervous system. Be sure to explain the physiological mechanisms behind these effects. Explain why a person who has

Assignment Essay Example | Topics and Well Written Essays - 2500 words - 4

Assignment - Essay Example There is an established communication between Adam (man) and God (divine). Adam is seen stretching his hand reluctantly and loosely to receive what God is presenting to him. God is trying to transmit some sought of divinity to man. This is being attempted by bringing their fingers as close as possible but it is clear the fingers do not establish a contact. This could be the impossibility of God and man being into contact. The story is biblical though and it has it that after Creation of Adam, God breathed life into him. In the bible there is nowhere we are told that there was a lot of resistance in the process. However, in the creation of man, the work presents an interesting fact (Kleetus, 2005). God is seen trying to reach Adam with all his might. He is stretching his index finger to touch that of Adam. It seems there is a resistance in form of a wind, which is trying to deny him a chance to communicate to his creation. The presence of a wind-like force is depicted in the direction of God’s legs and those of the angels surrounding him. The implication from the figure here is that God is trying with all his might to touch and transmit his mightiness to hid creation amidst a strong opposing force. On the other hand, dam does not seem to have the energy and effort to reach to God. Adam is relaxed and while God is using his right hand to reach him, Adam is using his right hand to support his lazily leaning body and reluctantly uses his left hand to respond to God’s attempt to reach him. The left hand has to be supported by his left leg knee for that case. Adam’s body is leaning against God and it seems he is not willing enough or putting enough effort to make the divine connection with God. The body language of the two is totally different and while one is responding with strength to establish a connection, the receiver is not so much putting an effort to receive. A closer look at the index fingers of the two subjects in

Advance managerial accounting Report Essay Example | Topics and Well Written Essays - 500 words

Advance managerial accounting Report - Essay Example This implies that data turns into information for purposes of making decisions. In the same way, Ferrara’s article â€Å"21st Century Paradigm,† the focus is on cost especially concerning industrial engineering. When Ferrara says that the volume of activity is still a problem as fixed costs grow depending on variable costs, the main point is that profitability is dependent costs. Just like Drucker, Ferrara proposes that costs affect the number of products. This is what he refers to as activity costing. In the two articles, authors clearly bring out the issue of marginal changes ignoring the impact of accounting. Data, therefore, is imperative in the two cases for continuous improvement like cutting down on the selling over a period. At the final stage, Drucker and Ferrara establish that information is crucial in any accounting system, whereby it should deal with the two issues of assigning costs between and within product lines. The next articles as well focus on utilizing costs to make decisions. Cooper and Kaplan, for instance, examine how important products are critical in controlling the costs within the market. They, at first, agree with Ferrara that costs are becoming less variable. This implies that they are the dependent factors transferring products to be independent. Cooper and Kaplan reveal that most costs change depending on the shift and diversity of products within the economy as opposed to the number of products produced (Kaplan and Atkinson 2). With reference to what Drucker tries to bring to surface on accounting systems and information, Cooper and Kaplan tend to agree with him that conventional accounting systems make more products appear more expensive than they really are. The clearest point that brings all the articles together is that management decisions vary depending on the number of product complexity as opposed to the amount. Cooper and Kaplan as well

How convincing is Durkheim's arguement that organic solidarity is a Essay

How convincing is Durkheim's arguement that organic solidarity is a normal development of the division of labour in society - Essay Example According to Durkheim, certain social facts such as family norms, formal laws and regulations exercise a form of coercive power on the members of a society, and these exist independently from its members (Martin & McIntyre 1994, p.433). Presented as thus, these social facts are a part of society which are functional but objectively self-existent within a society. In The Division of Labour, Durkheim explored the way in which a society shifts from its more primitive state to a modern society; through the content of its moral rules and stances, and also through the solidarity of its nature. In relation to the former shift, he expressed law as an assurance of a society’s fundamental values, as the moral values attached to individuals by individuals borne of human dignity. He assigned law the unifying value of society, calling it a ‘glorification†¦of the individual in general†¦sympathy for all that is human’ (Individualism and the Intellectuals 1889, p.273). As a form of coercive power in society, law depicts society as a moral unit, and we feel the force of this coercive power when we deviate from it. This is not to say that we are constantly aware of the coercive power within society; through the sharing of similar beliefs and goals, we as individuals are able to create the impression that such collective beliefs a re our own. Yet how can the members of a society co-exist with a set of moral values which are not a sum of its members individual values? It is as though Durkheim describes us a blank slates, upon which our entering into society is drawn a set of moral values by this separate entity – does this not undermine any autonomy that we could possess as individuals? Just because moral rules are obligatory does not mean that they are not a creation of the collective values and beliefs of its individuals. How can it be a ‘collective common conscience’, (Division of Labour in Society 1893,

The stochastic Poisson model Essay Example | Topics and Well Written Essays - 1000 words

The stochastic Poisson model - Essay Example The Poisson process is a stochastic process, which describes events that occur independently from one another and continuously. Stochastic processes are part of probability theory and are used to describe random processes. They are based on a level of indeterminacy, which means that the final outcome is unknown although some paths and outcomes are more likely than others. (Doob, 1953) The Stochastic Poisson model has been used to describe processes like rainfall, the telephone calls that arrive at a switchboard, radioactive decay of atoms, and the page views of a website. Its use to describe the decision making of a juror is a relatively new and exotic application. When applied to decision making a Poisson process can be catalogued as special case of renewal theory (Cox, 1962). This model was proposed by Thomas and Hogue (1976) as a descriptive model in juror decision making. The model describes the jurors choice making as a two step process. In the first place the juror must consider the evidence to create a final estimate of the weight of the case against or for the defendant. Secondly, each juror has an individual decision criterion that allocates the apparent weight of evidence into "for" and "against" decision zones. According to this model a juror will only decide against a defendant if the weight of evidence exceeds his personal decision criterion. This means that the confidence of a juror in any particular decision will be a mathematical function of the distance between the apparent weight of the evidence and their personal decision criterion. The further away these parameters are the stronger the confidence of the juror in a particular decision. The indeterminacy of this process lies in the assumption that the apparent weight of evidence, or the perception of the weight of evidence, is randomly distributed among jurors. Thomas and Hogues (1976) decided to use an exponential probability density function to describe the way jurors arrived at a

Select a country and analyze the recent state of their fiscal policy Research Paper

Select a country and analyze the recent state of their fiscal policy - Research Paper Example To ask which comes first is like asking the perennial question, â€Å"Which comes first, the chicken or the egg?† On the one hand, there is the leisure and pleasure travelers who come from around the world come to enjoy its pristine beaches and breathtaking coral reefs. Then while there, they make a little side trip to the business center to open an offshore bank account, invest in the stock market or buy the nice lot they have spotted while trekking. On the other hand, there are the business people on their nth business trip to the Caribbean islands to have their corporation or business registered. They are also there to buy stocks, invest in trust and mutual funds, or open an offshore bank account. And while waiting for their business to get processed, they check-in into a resort and go scuba diving on one of the island’s amazing reefs. Aside from its natural wonders, the government of this three-island country lures investors with its zero direct taxes. Yes, you hear d it right. The 57,000 Caymanians pay no direct taxes to the government. There is no tax on income, donation, and inheritance. Capital gains tax and corporate taxes are also unheard of in this Caribbean haven. Finally, there are no property taxes in Cayman Islands. At most the government collects a six percent to seven and a half percent (6% to 7.5%) stamp duty for the sale of real property, which is based on its value at the time of sale. There is also a one percent to one and a half percent (1% to 1.5%) fee that is collected for mortgages of real property (Cayman Islands Government FAQ). Simply put, for the Caymanians, it means that there is no need to declare your income, what your properties are, or any other assets for that matter (Cayman Islands Chamber of Commerce). The government does not collect data how much you earn, how much you spend or how much you owe. The government is not interested to know how you earned your wealth. They don’t care if you worked for it, inh erited it or received it as a gift. For the foreigners, zero direct taxes means there are no restrictions on land ownership. Foreigners can purchase land for as much as they can afford. There are no limits on investment opportunities. The government does not want to know what you invested into and how much money you put in a certain business. Foreigners can open as many bank accounts as they like. As a matter of fact, if you show up in person and present yourself for interview by the bank, you only need to present your passport to open an account. No certification of identification is necessary (Investing in Cayman) As a matter of fact, this zero direct tax system is the country’s major selling point to investors who are always on the lookout for better terms for their money. The primary industry of financial services, together with its allied professional services industry which includes lawyers, bankers, accountants, and financial advisors account for 55% of the countryâ₠¬â„¢s Gross Domestic Product (Teather 11). More specifically, this industry provides 12,500 jobs which is 36% of the employment rate of Cayman Islands. The 55% GDP actually account for 40% of the total revenue of the government. Finally, financial service is what brings in 30,000 visitors annually to the three islands of this Caribbean nation. I have focused my research and discussion on the zero direct tax rates in Cayman Islands because I

World War Ii and Military Organized Women Essay Example for Free

World War Ii and Military Organized Women Essay 1. The reason for mentioning WWI soldiers is during The Depression soldiers from WWI wanted a bonus that was promised them but wanted it early since they along with millions of others were facing desperate times. Not only did the government refuse to pay them but also the protest marches by the former soldiers were broken up and the camps they slept in burned. The song in general refers to how people were well employed building the country up before the economic collapse ended up literally begging for money or food just to survive. 2. Relief: Immediate action taken to halt the economies weakening. FDR authorized almost $5 million to implement work-relief programs. Hoping to lift the country out of the crippling Great Depression, Congress allowed the president to use the funds at his discretion. The act was unparalleled and remains the largest system of public-assistance relief programs in the nation’s history. Recovery: Temporary programs to restart the flow of consumer demand. FDR created programs focused on stabilizing the economy by creating long-term employment opportunities, decreasing agricultural supply to drive prices up, and helping homeowners pay mortgages and stay in their homes, which also kept the banks solvent. Reform: Permanent programs to avoid another depression and insure citizens against economic disasters. Reforms targeted the causes of the depression and sought to prevent a crisis like it from happening again. In other words,  financially rebuilding the U.S. while ensuring not to repeat history. 3. For African Americans during the war, businesses were beginning to boom at the time. Because very small percentage of African Americans fought in the war, it made jobs available. After WWII African American business owners and families had enough money to move out of crowded inner cities and into the suburbs. Of coarse, the migration of African American families to suburban areas led to white families relocating, which led to vacant homes resulting in lower property value in neighborhoods. This had social-economic impact on African American communities as the racial attitudes of the time still persist. Women: it gave them the ability to join the work force. Prior to WWII, women stayed home and took care of domestic affairs, or worked as nurses, secretaries, or teachers. Women during the war had to replace male workers who fought. When the men returned home women commonly went back to their traditional roles, while some remained at their jobs. Although, it still wasnt acceptable for women to work jobs typically done by men, the war allowed women to prove that they can. Japanese Americans were ostracized and put into concentration camps during WWII. After the war many people distrusted the Japanese and other Asian ethnicity in America for a while, which made it hard for them to advance. The treatment of Japanese Americans during and after the war isn’t our proudest moment and is seldom mentioned in our countries history. 4. Foreign Policy: Harding spurned the League of Nations and negotiated peace treaties with Germany and Austria. His greatest foreign policy achievement came in the Washington Naval Conference of 1921–22, in which the worlds major naval powers agreed on a naval limitations program that held sway for a decade. Xenophobia: Harding believed that the less we were involved in foreign  affairs the better. While he did deviate from this on several occasions his foreign policies were always directed towards reducing the chances of being involved in another conflict. Business in America: Harding followed a predominantly pro-business, conservative Republican agenda. Taxes were reduced, particularly for corporations and wealthy individuals; high protective tariffs were enacted; and immigration was limited. Harding signed the Budget and Accounting Act of 1921, which streamlined the federal budget system and established the General Accounting Office to audit government expenditures. Section 2: The war had a dramatic impact on women. The sudden appearance of large numbers of women in uniform was easily the most visible change. The military organized women into auxiliary units with special uniforms, their own officers, and, amazingly, equal pay. By 1945, more than 250,000 women had joined the Womens Army Corps (WAC), the Army Nurses Corps, and Women Accepted for Voluntary Emergency Service (WAVES), the Navy Nurses Corps, the Marines, and the Coast Guard. Most women who joined the armed services either filled traditional womens roles, such as nursing, or replaced men in non-combat jobs. During World War I, the first demonstrations were held to give women the right to vote. Women also substituted for men on the home front. For the first time in history, married working women outnumbered single working women as 6.3 million women entered the work force during the war. The war challenged the conventional image of female behavior, as Rosie the Riveter became the popular symbol of women who abandoned traditional female occupations to work in defense industries. Social critics had a field day attacking women. Social workers blamed working mothers for the rise in juvenile delinquency during the war. On top of everything else there were shortages: food, clothing, transportation, cosmetics and eligible men. There were long hours of hard work, there were sons, husbands and fathers to bury. Women had their share of problems, but they survived and persevered. In closing the world wars changed America in many ways. Both the roles of men and women changed drastically and still to this day most of those changes are still taking affect in society.

Dual Trapezoidal Fuzzy Number and Its Applications

Dual Trapezoidal Fuzzy Number and Its Applications Jon Arockiaraj. J, Pathinathan.T, Revathy.S Abstract: In this paper, we introduce Convergence of ÃŽ ±-Cut. We define at which point the ÃŽ ±-Cut converges to the fuzzy numbers it will be illustrated by example using dual trapezoidal fuzzy number and Some elementary applications on mensuration are numerically illustrated with approximated values. KeyWords: Fuzzy number, ÃŽ ±-Cut, Dual trapezoidal fuzzy number, Defuzzification. Introduction: Fuzzy sets have been introduced by Lotfi. A. Zadeh (1965). Fuzzy numbers were first introduce by Zadeh in 1975.There after theory of fuzzy number was further studied and developed by Dubois and Prade, R.Yager Mizomoto, J.Buckly and Many others. Since then many workers studied the theory of fuzzy numbers and achieved fruitful results. The fuzziness can be represented by different ways one of the most useful representation is membership function. Also depending the nature and shape of the membership function the fuzzy number can be classified in different forms, such as triangular fuzzy number, trapezoidal fuzzy number etc. A fuzzy number is a quantity whose values are imprecise, rather than exact as is the case with single valued number. Fuzzy numbers are used in statistics computer programming, engineering and experimental science. So far fuzzy numbers like triangular fuzzy number, trapezoidal fuzzy numbers, pentagonal, hexagonal, octagonal pyramid and diamond fuzzy numbers have been introduced with its membership functions. These numbers have got many applications like non-linear equations, risk analysis and reliability. In this paper, we introduce Dual trapezoidal fuzzy numbers with its membership functions and its applications. Section one presents the introduction, section two presents the basic definition of fuzzy numbers section three presents Dual trapezoidal fuzzy numbers and its applications and in the final section we give conclusion. 2. Basic Definitions Definition 2.1: (Fuzzy set) A fuzzy set A in a universe of discourse X is defined as the following set of pairs A= {(x,  µA(x)): xX} Here  µA(x) : x is a mapping called the degree of membership function of the fuzzy set A and  µA(x) is called the membership value of xX in the fuzzy set These membership grades are often represented by real numbers ranging from [0, 1]. Definition 2.2: (Fuzzy Number) A fuzzy set A defined on the universal set of real number R is said to be a fuzzy number if its membership function has satisfy the following characteristics. ( i) ÃŽ ¼A (x) is a piecewise continuous (ii) A is convex, i.e.,  µA (ÃŽ ±x1 + (1-ÃŽ ±) x2) ≠¥ min ( µA(x1),  µA(x2)) É  x1 ,x2R É  ÃŽ ±[0,1] (iii) A is normal, i.e., there exist xo R such that  µA (xo)=1 Definition 2.3: (Trapezoidal Fuzzy Number) A trapezoidal fuzzy number represented with four points as A = (a b c d), Where all a, b, c, d are real numbers and its membership function is given below where a≠¤ b≠¤ c≠¤ d  µA(x)= 3. DUAL TRAPEZOIDAL FUZZY NUMBER Definition 3.1: (Dual Trapezoidal Fuzzy Number) A Dual Trapezoidal fuzzy number of a fuzzy set A is defined as ADT= {a, b, c, d (ÃŽ ±)} Where all a, b, c, d are real numbers and its membership function is given below where a≠¤b≠¤c≠¤d  µDT(x) = where ÃŽ ± is the base of the trapezoidal and also for the inverted reflection of the above trapezoidal namely a b c d Figure: Graphical Representation of Dual Trapezoidal fuzzy Number 3.2 DEFUZZIFICATION: Let ADT= (a, b, c, d, à °Ã‚ Ã¢â‚¬ ºÃ¢â‚¬Å¡) be a dual trapezoidal fuzzy number .The defuzzification value of ADT is an approximate real number. There are many method for defuzzification such as Centroid Method, Mean of Interval Method , Removal Area Method etc. In this Paper We have used Centroid area method for defuzzification . CENTROID OF AREA METHOED: Centroid of area method or centry of gravity method. It obtains the centre of area (X*) occupied by the fuzzy sets.It can be expressed as X* = Defuzzification Value for dual trapezoidal fuzzy number: Let ADT= {a, b, c, d (ÃŽ ±)} be a DTrFN with its membership function  µDT(x) = Using centroid area method +dx+++dx = + + + + + = = = ++ dx+++dx = = = c + d – a b Defuzzification = = = 3.3 APPLICATION In this section. We have discussed the convergence of à °Ã‚ Ã¢â‚¬ ºÃ¢â‚¬Å¡-cut using the example of dual trapezoidal fuzzy number. CONVERGENCE OF ÃŽ ±-CUT : Let ADT = {a, b, c, d, (à °Ã‚ Ã¢â‚¬ ºÃ¢â‚¬Å¡) } be a dual trapezoidal fuzzy number whose membership function function is given as  µDT(x) = To find à °Ã‚ Ã¢â‚¬ ºÃ¢â‚¬Å¡-cut of ADT .We first set à °Ã‚ Ã¢â‚¬ ºÃ¢â‚¬Å¡ [0,1] to both left and right reference functions of ADT.

Centroid area method: X* = = = = = 34 The approximate value of the perimeter of the rectangle is 34 cm. 2.Length of Rod: Let length of a rod is a positive DTrFN ADT = (10cm,11cm,12cm, 13cm). If the length BDT = (5cm, 6cm , 7cm, 8cm), a DTrFN is cut off from this rod then the remaining length of the rod CDT is [ADT(-)BDT] The remaining length of the rod is a DTrFN CDT = (2cm, 4cm, 6cm, 8cm) and its membership function  µDT(x) = The remaining length of the rod is not less than 2cm and not greater than 8cm.The length of the rod takes the value between 4cm and 6cm. Centroid area method: X* = = = = = 5 The approximate value of the remaining length of the rod is 5cm. 3.Length of a Rectangle: Let the area and breadth of a rectangle are two positive dual trapezoidal fuzzy numbers ADT=(36cm,40cm,44cm,48cm) and BDT=(3cm,4cm,5cm,6cm) then the length CDT of the rectangle is is ADT(:)BDT. Therefore the length of the rectangle is a dual trapezoidal fuzzy number CDT=(6cm,8cm,11cm,16cm) and its membership functions  µDT(x) = The length of the rectangle is not less than 6cm and not greater than 16cm .The length of the rectangle takes the value between 8cm and 11cm. Centroid area method: X * = = = = 10.38 The approximate value of the length of the rectangle is 10.38cm. 4. Area of the Rectangle: Let the length and breadth of a rectangle are two positive dual trapezoidal fuzzy numbers ADT=(3cm,4cm,5cm,6cm) and BDT=(8cm,9cm,10cm,11cm) then the area of rectangle is ADT(.) BDT Therefore the area of the rectangle is a dual trapezoidal fuzzy number CDT= (24cm, 36cm, 50cm, 66cm) and its membership functions  µDT(x) = The area of the rectangle not less than 24 and not greater than 66.The area of the reactangle takes the value between 36 and 50. Centroid area method: X * = = = = 44.167sq.cm 4.CONCLUSION: In this paper, we have worked on DTrFN .We have define the Convergence of ÃŽ ±-Cut to the fuzzy number. We have solved numerically some problems of mensuration based on operations using DTrFN and we have calculated the approximate values. Further DTrFN can be used in various problem of engineering and mathematical science. 5.

The Use of Punctuation in the Writing of Libyan Students Essay

Punctuation in English Parkes (1992), in his invaluable study of the history of punctuation, states: "Punctuation was developed by stages which coincided with changing patterns of literacy, whereby new generations of readers in different historical situations imposed new demands on the written medium itself' (p. 2). Punctuation is not a static model and even if we confine the discussion to early modern and modern English, it has changed quite considerably across time (Numberg, 1999). The uses of punctuation are conventional; they change over time and vary from language to language. There have been to be conventions or rules, for without these, punctuation would be wholly idiosyncratic and the possibilities of using it to facilitate effective communication would be either lost of severely hindered (Beard & et al., 2009). Some rules of punctuation are mandatory: if we violate them, we have made mistakes in punctuation. Others are optional: our choice is basing on the effect and emphasis we desire to deliver. To that extent, Greenbaum and Nelson (2002: 183) say â€Å"punctuation is an art.† There was a considerable debate between two schools: one believed punctuation should be based on elocution (how a sentence is spoken when it is read out aloud) and the other believed punctuation should be based on the grammar (Petit: 2003; Curtis, 2007; Hall and Robinson, 1996; Parkes, 1992). The latter (the syntactic-based approach) is the one we use today, which means the debate was won by grammar school. Recently, Dawkins (2003 and 1995) has come out with a new believe: teaching punctuation should be based on the meaning (the semantic- based approach). Dawkins (2003) assumes that writers have an intuitive sense of the independent claus... ..., p. 349). Moreover, Chiang (1999) claims that in EFL writing, the sentence(s) may appear to be appropriate order, but in incongruent places due to inappropriate use or non use of punctuation. Using the premise that students often have weak language skills, Warner (1979) surveyed 431 postsecondary students using four tools: student’s scores on an objective test, an in-class writing sample, an editing exercise, and a questionnaire about background in English and attitude toward grammar and writing. She found that the largest number of errors in the writing occurred in punctuation. She came out with: The high error rate in punctuation resulted from 1) the students not knowing the rules of punctuation, 2) knowing the rules but not being able to apply them to their own writing, or 3) constructing such poor sentences that correct punctuation was impossible (p.18).

Essay --

By now, R.K Narayan took a turn from his usual way of writing. Moving away from writing books, which were more or less auto-biographical, his exposure to foreign lands would have inspired him to move beyond his world and hone his creativity. Starting right from ‘Mr. Sampath’ (1948) to ‘The Vendor of Sweets’ (1967), this trend was seen in all books written in this period. ‘The Guide’ and ‘The Man-Eater of Malgudi’ is analyzed here, in this context. ‘The Guide’ is R.K. Narayan’s best and most famous work. A 1958 novel, it won the SahityaAkademi Award for English in 1960. It was made even more famous and popular by the on-screen immortalization by DevAnand and WaheedaRahman in the 1965 movie of the same name. Tracing the story of Raju, commonly called ‘Railway Raju’, the novel delineates his transformation from being a railway shopkeeper’s son to a sought after tour guide to later on become the country’s most famous saint. Raju, who took over his father’s shop after his death realized that taking people around the city of Malgudi as a tour guide is his forte. His life witnesses an upheaval when he is attracted to one of his customers, Rosie, a married woman who is neglected by her workaholic husband, Marco. Rosie’s potential to become a successful dancer, which is overlooked and ignored by her husband is spotted by Raju who encourages her to dance more. Following this, Rosie separates from her husband and rises to fame as a Bharatnatyam dancer with Raju’s help. A mistake by Raju, later on earns him a two-year prison sentence. On his release from prison, Raju is mistaken to be a saint. Following a series of interesting events, Raju takes on h imself a 12 day hunger-fast to pray for rains in the drought-stricken area. The story ends ... ...t manner in ‘The Man-Eater of Malgudi’. The underlying essence of the novel is based on the age-old saying which says that a man’s deed leads him to his destination. Inspiration from the Bhasmasura’s myth is also seen in the book. Vasu is compared to being a ‘rakshas’ (demon) who causes his own downfall himself. The 1954 KumbhMela stampede, which killed about 800 people seems to have affected Narayan as he mentions deaths due to stampedes in his book. While Nataraj is attempting to persuade Vasu not to create a ruckus during the procession, Vasu talks about how ‘melas’ are held to manage the population of the nation and to keep it under control. Population explosion of the 1950’s and 1960’s would have been the source of inspiration for this mention, which is taken up again in ‘The Painter of Signs’ where the female lead works on the issue of population control.

Loss of Innocence in Truman Capotes In Cold Blood Essay -- In Cold Bl

"All things truly wicked start from an innocence,† states Ernest Hemingway on his view of innocence. Innocence, what every youth possesses, is more accurately described as a state of unknowing but not ignorance- which connotation suggests a blissfully positive view of the world. Most youth are protected from the harsh realities of the adult world. Therefore they are able to maintain their state of innocence. While innocence normally wanes over time, sometimes innocence can be abruptly taken away. Some of the characters in Truman Capotes In Cold Blood lost their innocence due to the traumatic events they experienced in childhood and adulthood while some had none to begin with. Innocence can be stolen but the desire to return to the innocent state cannot. A traumatic event changes the nature of a small town, yet leaves some residents with a fervent desire to return to normalcy. An isolated city such as Holcomb is thought to be safe from the corruption and crime of city life. In 1959, the town of Holcomb was devastated by the brutal killings of a beloved family, the Clutters. This event completely changed the attitudes of most of the town’s population, which one resident, Mryt Clare, stated had turned them into â€Å"snakes†. While the once blamelessness that had been evident in most of the towns folk had disappeared, Clare had hoped the town would stop â€Å"scaring each other to death†. Clare wanted the usual kindness and innocence that drew her to the town to be restored. The deaths of the Clutter family had taken away the towns trust in one another, but the deaths of the killers and re established some of the innocence they had lost. While no one can completely recover from a traumatic event, the town of Holcomb desired to return to a st... ... become the victims. In the case there was never any innocence present in an individual, the choices they make will shape how corrupt they become. The town of Holcomb was traumatized by the unexpected murder of a respected family, which turned the community into distrusting gossipers. This event can take place in childhood, as it did for Perry Smith, who grew up with no protection from corruption by his parents and killed an entire family. Dick Hickock, impulsive and shallow, formulated a plan to rob and kill any witnesses present at the Clutter household. He was corrupt enough to go ahead with the plan and persuade Perry to kill the witnesses. Innocence must be protected to ensure that others may be kept innocent. The virtuous quality that most people have is connected to their innocence, but if their innocence is lost, their future may be condemned to sinfulness.

Protein Article Research

Protein Article Research Sara Langrell December 15, 2011 Nutrition SCI/241 Dr. Venessa Lee Abstract: Athletes have been searching for years for a way to reduce the amount of recovery time between work outs. Based on this issue there has been quite a lot of research conducted to find out what can be done, if anything, to either reduce or eliminate recovery time. One of the theories is to increase protein intake above the daily recommended amount, thereby providing the body with additional amino acids that promote recovery. Although this seems like the perfect solution, there are some flaws. It would appear that not only do you need additional proteins but an additional source of fuel to allow the proteins to do their job, therefore all in all a balance must be struck. The recovery time needed from an intense work out is a direct result of the lengthening, or even sometimes, tearing of muscles. If the work out is too intense muscles can actually be damaged. The damage can be classified into three different categories: Type I, Type II and Type III. Type I muscle damage is classified as the soreness that occurs 24-48 hours after unaccustomed exercise. Type II is classified as an acute disabling pain either from the complete tearing of the muscle and facia or the disruption of a few fibres with the facia remaining intact. 1 Type III is classified as a cramp or soreness that occurs either during or directly following a workout. 1 Because of these issues, many hours of research have been conducted to try to determine if there is anything that can be done to slow or even elimi nate the damage done to the muscle during exercise. When muscles are stretched or damaged proteins are both broken down and synthesized all at the same time. The breakdown is not all bad for the body, as it regulates potentially damaging and dysfunctional proteins. 2 In direct response to the breakdown, the synthesis that occurs would seem to be good for the body; however it can cause an imbalance in muscle proteins. 1 Based on research it has been determined that replacing amino acids during and after exercise helps to balance the protein deficiency and assist in the repair process. Many of the recommended ways to do this is to increase protein intake or possibly opt for an amino acid replacement supplement. Dependent upon the type of exercise you are prone to will determine the type of supplement that would be recommended. Checking with a physician would be the best bet before beginning any type of therapy.

Protein Article Research Anonymous Dr. Louis Cohen SCI/241 Protein Article Research January 3, 2012 According to Centers for Disease Control and Prevention, protein is found in every cell in the body. Protein provides our bodies with energy that is ready to be used. After it is digested, it becomes amino acids. There are 23 amino acids which are very essential to the body and are needed for the body to function properly. Amino acids are needed in order to build muscle strength. Protein can be found in animal foods, and it can also be found in plant foods.Animal foods such as meats, cheeses, and dairy products are complete sources of protein, while plant sources are an incomplete protein source because they are low in at least one of the essential amino acids. Plant sources need to be consumed with a complementary protein source in order to be certain that protein needs are being met. For example, if you eat chicken, that would be a complete source of protein, whereas if you eat rice for a meal, you should ad d beans to make the protein consumption complete. A few examples of plant sources or an incomplete protein source is as follows: corn, tofu, grains, some vegetables and fruits.Because I am a 19 year old woman, I need 46 grams of protein a day. I can easily meet and exceed the amount that is necessary by eating all of my meals in a day and by consuming all other essential nutrients. Although getting just the right amount of protein is healthy for the body, getting too much can be harmful. When people consume too much protein, they increase their risk of weight gain. Also, high protein diets can put a strain on the kidneys because they rid the protein from the blood, may contribute to cancer because it increase blood levels of IGF-1, and may cause nutritional deficiencies.Just as high protein diets can cause medical illnesses, low protein diets can do the same. A diet with a lack of protein can cause skin pigmentation, diarrhea, swollen bellies, rashes, and change in texture or color of the hair. Protein is on the body’s essential needs, however, too much or too little of any nutrient that is essential can harm the body. It is vital that people learn the amounts of nutrients their body requires in order to become or remain healthy.

Feminist Times: a Jury of Her Peers Essay

Susan Glaspell was born in 1882; she wrote a short story called â€Å"A Jury of Her Peers† based on her play Trifles. Susan Glaspell received a degree in philosophy from Drake University. She became a newspaper reporter in Des Moines. The writer married a freethinker who believed in free love. In 1916 the author was inspired to write the play Trifles based on a murder case she covered on the job. One year later in 1917, she creates the short story. Mrs. Glaspell has stated that promotes all progressive movements. Her short story â€Å"A Jury of Her Peers† is very touching and judgmental. In her story she is revealing moments that define the women’s personalities and lives. This short story is symbolizing how the women felt, what roles they play in society, and what the women saw as a worry was considered little to none importance by men. In this short story, how women felt was of no matter. For instance, Minnie Wright’s life was compared to the life of a bird in a cage. Mrs. Wright’s life was full of loneliness with nowhere to go. She was trapped in a cage just like the bird. Mrs. Hale remembered Minnie Wright as Minnie Foster before she got married to John Wright. Mrs. Hale states that Minnie Foster once had a beautiful voice just like the bird once had one too. â€Å"I wish you’d seen Minnie Foster when she wore a white dress with blue ribbons and stood up there in the choir and sang.† (Glaspell, Page 264) The beautiful voice of both Minnie Wright’s and the birds was taken away by a heartless man. Men in those times had no respect for how women felt. John Wright was a cruel man who killed the bird with disregard to her feelings. As the bird died, a piece of her heart died as well. â€Å"She was going to bury it in that pretty box.† (Glaspell, Page 264) Her only friend and connection to the world was taken away. As a consequence, Mr. Wright’s life was taken.   During the old time, the role that women played in society was based on their husbands. For example, Mrs. Hale was married to Mr. Hale who was a farmer. She was known as the farmer’s wife. Mrs. Peters was married to Mr. Peters who happened to be the sheriff. In the eyes of society she was known as the lady married to the law. In the book Mr. Peter’s states â€Å"Married to the law!† (Glaspell, Page 265) These women have no individual identity. Who they were, was determined by their husbands. The women were never called by their first names. They were called by their husband’s last name. In those days, women had no say or opinion. They had to do what their husbands would tell them to do. Who they would be for the rest of their life was established by the man they married. Decades ago, what women saw as a worry was considered little to none importance by men. Men back then were ignorant to what was obvious and right in front of their faces. The women saw the small details of what was happening or did happen. They put those small details together and found the motive as to why Mrs. Wright killed her husband. In the story â€Å"A Jury of Her Peers,† Mrs. Hale and Mrs. Peters noticed all the small details that were clues. When Minnie asked that they check on her preserves. Mr. Hale commented â€Å"women are used to worrying over trifles.† (Hedges, web)The quilt was one of the clues that gave the ladies a scare. They were trying to figure out why the quilt was done so well, but towards the middle looked wrong. The ladies were puzzled as to if Minnie Wright was going to knot or quilt it. They understood that it described Minnie’s life. It looked nice and pretty on the outside, but on the inside her life was mess. The men didn’t see or understand it. Mr. Henderson the county attorney made a brief smirk about the ladies wonders. â€Å"They wonder whether she was going to quilt it or just knot it!† (Glaspell, Page 260) The ladies knew something was very wrong. The men saw it as nothing. The women found a beautiful little box at the bottom of the sewing basket. In the box they found a dead bird, but did not mention it to the men. The men were too busy looking for the big clues that they found nothing. All the small details that would convict Minnie Wright were in her personal belongings. Everything that had to do with her everyday life was considered small details or of no value in the men’s eyes. In reality, it was all the clues they needed, but overlooked. The small worries of women should never be underestimated and should be considered when trying to understand them. A woman’s small worries are the clues to discovering the answers. In this mystery of finding all the right clues, the two ladies found them all. This story shows that women are just as smart as men. Sometimes women are even smarter. These two ladies read between the lines and figured out Minnie Wright’s life story in just a short period of time. â€Å"For these women, solving the murder is not a disinterested act, but a cooperative endeavor which leads them to a knowledge essential for their survival as females in a hostile or indifferent world.† (Ortiz, web ) As the men searched for big clues, they found nothing. The women understood what Minnie had endured in her life and choose not to tell the men about the clues. It was their choice not to tell the men and none of them would ever know that the ladies had defied them that day. It was one step closer to gaining their rights.

Racial disparity Essay

Prevalence of racial disparity in the criminal justice system is most troubling and critical problem for criminal justice executives as it directly affects the people. The safety and liberty of American people depend on integrity of American justice system but racial discrimination in the criminal justice system impairs this integrity, which in turn harms American people directly. So this is the most critical dilemma facing the criminal justice system managers at present. The causes of this racial discrimination are both subtle and intricate and are not easy to locate. However it is obvious that fault does not lie with American criminal laws but these are implemented in a manner that is substantially and pervasively biased. Certain factors external to American criminal laws like personal discretion, natural proclivity and mental approach of the people that responsible to implement these laws, also collaborate rendering distortion of these laws. This institutional materialization of racial discrimination in the justice system is the most critical people predicament facing mangers of American criminal justice system. Although certain legal reform has been suggested by various sector but past history manifests that criminal justice manager cannot simply legislate to put an end to this problem. Some concrete measure should be undertaken by criminal justice manager to solve this problem rather than redefining criminal justice system.

My Thoughts On Ethnicity and race Essay

Race and ethnicity is a very interesting topic to think about. The distinction between race and ethnicity is not always clear to a lot of people. To me race is your physical appearance and ethnicity is your cultural background. My race is white but my ethnicity is Irish and scottish. Although my race is white and someone who is polish might also be white our cultures are not the same. When you are asked to specify race/ethnicity on a form i think it is not fair because there are thousands of things you could potentially be that dont neccesarily fit into the small choice of boxes they give you. I think a lot of people don’t know the difference because race and ethnicity are often listed together leading people to think that they are the same thing I don’t think race and ethnicity should be an issue. Any one person no matter what background they are from was born and will die just the same. It is natural for people to want to group themselves with others who look, speak or behave in similar patterns. Essentially humans are animals and most animals are more comfortable with the familiar. Athough it is natural to group ourselves organically in this way, i dont think having to catogorize yourself into a group on forms and surveys is ever going to help anything. Throughout my life I’ve had a lot of contact with many different ethnicities and races. I went to school where the i was not part of the majority. I was one of the few white people in my class and it was a big issue for me then because being the minority i was treated differently. I was frequently called â€Å"the white girl† by my classmates. At first it bothered me but I became more comfortable. I think being the minority in school helped me learn how to get along with people from different backgrounds. My ability to get along with almost anyone i can attribute to my experience in school. I have also gained a soft spot for anyone getting treated differently for their race or ethnicity. I have heard friends and family make remarks about race but it isnt often that they are positive. A nearby neighborhood is going through a gentrification. The rents in the area have incresed leading people in the area to move into my neighborhood. The people moving in are mostly black and hispanic. Many people are attributing the rise in crime in the area to the people that have been migrating in. Before this migration the neighborhood was mostly Italian, Irish and german. I dont know what to think about this development but i hear a lot of predjudiced things being said that i dont agree with. I think most negative comments come from learned steriotypes. These things can be learned from family, friends or even the media. Many people have the potential to be predjudiced to a certain degree but for the most part i think it is a learned behavior. I believe in the future as races and ethnicities become more and more mixed that prejudice will decrese drastically. Any advantages of stressing these racial and ethnic issues i believe is to try to be fair. One of these advantages is the government requires some companies and schools to hire/accept a certain quota of minorities. This is good because it gives a lot of people opportunities that they might not have gotten because of someone being prejudiced against them. I also think it could be a litte unfair because someone more qualified might not get a spot because of these quotas. I think how you turn out socially, economically, and morally is attributed to your family. If you are from a rich family you are born knowing what having money is like and how to manage it. If you are born poor it is much more difficult to move out of the cycle of poverty. It is because of this that some people see minority communities in a bad light but i just think they are stuck in the cycle of povery. Minority families not so long ago were kept down by racism. Most politicians are prodominantly white at the moment. Once politics become more diverse i think the balance of wealth will begin to shift and ethnicity/race will become less important. Ethnicity and race is a topic of great interest to many people. It affects our laws, advertizing and a plethora of other things. I personally dont feel like it should matter at all what you are on the outside or what culture you have. We are all people and i hope one day that everyone can just treat everyone the same regardless of race or ethnicity.
