Adaptive User Interface Framework: Android Mobile Platform
adaptational exploiter Interface Framework humanoid runny PlatformMr. Tulip Das twitchAdapting a graphical embrasure (GUI) to a range of resources with completely distinct capabilities is exciting topic of liquid computer. The substance ab exploiter porthole compeld for an industry ought to pass its layout and parts to the exploiter need and changes for every drug substance absubstance ab drug drug user. We propose a perplex for rambling screenings to form the user portholes adaptable for user. This identifies an set aside expertise train to a user by learning his/her history of inter solveion. Dynamic App cutoff is to be provided on Mobile Devices serving to user to swipe the separate m whatsoever time to search out the required app. The prediction model utilizes multiple options together with recency, frequence, duration, time distribution and app sequence launch.KeywordsHCI in Mobile AI and expert establishments adjustive user interface cloth k-means algorithmic rule propellent shortcuts peregrine app usage personalization.)I. IntroductionAn adjustive user interface (also known as AUI) is a user interface (UI) which adapts, that is changes, its layout and elements to the needs of the user or place setting and is similarly alterable by apiece user. These reciprocally reciprocal qualities of both adapting and being adaptable are, in a full-strength AUI, also innate to elements that comprise the interfaces brokers portions of the interface might adapt to and ingrain other portions of the interface. The user adaptation is much a negotiated process, as an adaptive user interfaces designers ignore where user interface components ought to go while affording a means by which both the designers and the user can determine their placement, often (though not al authoritys) in a semi-automated, if not fully automated manner. An AUI is primarily created establish on the features of the system, and the cognition takes of the users that entrust utilize it.Figure 1 Adaptive Graphical exploiter InterfaceThe advantages of an adaptive user interface are found inwardly its ability to conform to a users needs. The properties of an AUI allow showing only relevant instruction ground on the current user. This creates less confusion for less begind users and provides quiet of ariseing throughout a system. Depending on the task, we can increase the stability of a system. An adaptive user interface can be apply in various ways. These implementations can differ between the amount of information available to certain users, or how users utilize the application.Adaptive presentation The refinement behind adaptive presentation is to display certain information based on the current user. This may mean that users with only basic knowledge of a system will only be shown minimal information. Conversely, a user with advanced knowledge will have access to much than detailed information and capabilities. A way that the AUI can achieve this specialisation could be to hide information to be presented based on the users experience take aim. Another possibility is to control the amount of links to relevant sources on the page.Adaptive navigation Adaptive navigation intends to guide a user to their specialised goal within the system by altering the way the system is navigated based on certain factors of the user. These factors can include the users expertise level with the system/subject, the current goal within the system, and other relevant factors. Examples of adaptive navigation can be achieved in many another(prenominal) ways, similar to adaptive presentation. These can include examples such as providing links to help achieve a users specific goal, giving reference on a page to where a user is, or altering the resources available to the user.II. MOTIVATIONIn the last few years, an ecosystem of doojiggers and heterogeneous run has emerged with a huge garland of capacities and characteristi cs. These freshly devices, along with applications and services, must be utilise to enhance the quality of life, making the users occasional activities easier, as well as increasing their personal autonomy.User interfaces in mobile applications are complex since they need to provide sufficient features to variety of users in a restricted space where a small subject of components are available. When user acquires expertise in the system they expect user interfaces which satisfy their unique needs. Therefore, user interfaces in mobile applications should be sufficient to different users. Since this problem exists in various applications a general antecedent is required to make user interfaces adaptive utilize user context history.Figure 2 Different Mobile DevicesIn this sense, there is a clear need for creating interfaces that adapt themselves taking into account characteristics of the user, context, application and device. iodin of the aspects to consider when adapting interf aces is the set of preferences of the user. When using different applications or devices, each user has different preferences, generally related to their limitations.III. Problem StatementUsing mobile and its application is a personalized experience. Each user has different preferences, mainly related to their limitations. Hence it is quite essential to account characteristics of the user, context, application and device while designing a Graphical User Interface for mobile platform. It is quite difficult to manage when there are many applications (apps) installed on a mobile device, the simple task of launching an app could become inconvenient, as the user may need to swipe the screen several times to and the desired app. Hence an adaptive user interface solution for mobile devices, which uses dynamic shortcuts to facilitate app launching is needed. In this context, personalization of applications, i.e. applications that adapt themselves to users capacities and limitations is ess ential.IV. Problem modelA. OverviewRather than providing adaptive user interfaces for a specific mobile application, it is more valuable if it would be a common solution to make any UI adaptive. So it is encouraged to provide a framework which can put a common solution which can be used by all developers to create applications which provide adaptive user interfaces. This framework provides Adaptive User Interfaces based on users experience level. The experience levels are categorize by Inference Engine which is explained in the subsection Inference Engine. The system will learn the user experience level based on user actions performed on each component of the application with the algorithm.Figure 2 Concept of Adaptive User InterfaceFigure 3 mental faculty diagram for the system with Adaptive User InterfaceB. Components of SolutionThe proposed adaptive user interface is mainly focused on hiding aggroup of unwanted components for corresponding experience level of user on that app lication.The framework consists of three main phases such as1. Data preprocessing timbre2. acquirement step3. Execution and variant stepData preprocessing step1. stance Data One of the factors to adapt the UI is the location of the user. This is based on the preface that the compositors case of applications a user is expected to access when at ingleside is different from the type of applications accessed when the user is at work. The location is determined by means of the GPS sensor on the mobile device.2. Device Data turnout of other sensors on the device including the ambient light sensor (to recoup whether the user is indoors or outdoors), accelerometer and gyroscope (to say if the user is nonmoving or moving) can also be used to derive additive contextual information in order to better predict the users chosen application and modify the UI appropriately.3. App usage Data Logs of the past application usage, the frequency at which the particular app was accessed and th e user actions and interactions while using the app can act as another source of contextual information.4. Time Data The type of applications accessed on weekdays might be different from the applications accessed on a weekend or on holidays. Similarly, in the morning the user may access different apps than the ones they do at night. A logging service zip in the device would have to log the types of apps accessed at specific times of day or day or the week, and use it to make the appropriate UI modifications.C. Learning stepThe main purpose of induction locomotive engine is to fool the info provided by the data-preprocessing module and provide an experience level of the user according to the current user context. To infer the experience level of the user, the inference engine should behave as an intelligent system which should be apt by data related to user experience level and user interactions between the applications.Figure 4 A High level computer architecture of adaptive u ser interface frameworkExecution and description step K-means flocking engine is capable of setting the number of clusters needed. When the number of clusters is set, the engine can cluster the dataset when the squared error becomes minimized. This will give each clusters meaning points as output. Once the cluster centers are found these cluster centers will be delivered to user type chooser. User type selector will appoint each experience level to each center sent by K-means clustering engine. occurrently we have manually prescribed the experience level for identified centers using natural knowledge. As mentioned earlier who masters the system can suggest these levels for each cluster values. Current user context data will be feed into the User type selector and user type selector will infer a suitable experience level which is closest. This final output will be delivered to the execution and rendering step.D. ImplementationIn order to very much show the behavior of the frame work a proof of concept (POC) application will be developed. A simple application which can be used as an online ticket reservation system for aircrafts will be developed as the application. This application was developed in Hyper Text Markup address (HTML) and JavaScript. mechanical man platform has given enough features and Application Programming Interfaces (API) to create an Android application using HTML and JavaScript.Android web application can be created by converting a HTML page to an Android web application using WebView class. Currently there are many third party frameworks and plug-ins are available to convert HTML and JavaScript pages to Android application.This application will be connected to adaptive UI framework using a component called UIhooks. UIhooks are any(prenominal) methods which can be used by the developer during the application development. For example these methods can be used when some events are fired on UI components. When UIhooks are called they ar e developed in a way to throwaway the user actions performed on corresponding UI component and store them. For example when a UIhook method is called on a freeing on click event, the Uihooks is implemented to measure how many time the button was clicked and what is the recent time it was used. If UIhook method is called on a textbox on resign event the Uihook can inspect and store the value deferted and the count of submit action performed. This application is sent to a user study to store readying data. This is elaborated more in User study section. The accumulate data were organized and feed to inference engine as the training dataset. Inference engine learned the data as elaborated before and gave the suitable experience level. Once the experience level is feed to the rendering engine it finds the related rendering logics inside the UI clusters. For example if the experience level is provided as intermediate it checks for the corresponding rendering logics and UI clusters . If it is said as If user Type is intermediate render cluster2 it will build a new UI using what is mentioned in cluster2. Then it renders it to the user. When the user is provided with new adaptive UI a question will be provided to the user asking whether they are conform to with the new UI or they want to go back to the earlier stage. This is to measure their satisfactory level and the accuracy of the algorithm predictions.V.

ConclusionThe aim of our study was to propose a high level architecture for a framework to provide adaptive user interface for mobile applications. This fram ework includes data preprocessing step, learning step and execution and rendering step to deliver asuitable user interface. The learning is through by an intelligent system which is unsupervised and trained using user context data. This delivers k number of experience levels by clustering the serene data set using K-means and ANN algorithm. It will also allow dynamic shortcuts to facilitate app launching. Some other options to enhance the proposed dynamic shortcuts solution such as gesture based control will also be explored in the future.VIII. ReferencesAztiria, A. Castillejo, E. Almeida, A.

History of Volleyball
History of volley fruitcake gameDan GouldMr. WoodmanseeWilliam G. Morgans Minto nettte and its phylogenesis to the popular international sport, has changed in many a(prenominal) different ways to locomote the more modern day sport called, Volley clump. volleyball was founded in 1895, by a man give eard, William G. Morgan, in Holyoke, Massachusetts. It was originally called Mintonette, and was meant to be a combination of Basketball, Baseball, and Handball. withal, it was designed to be a non-contact sport so that no one got hurt. There was no limit to the number of players on a group, nor was at that place a limit to the number of contacts on each(prenominal) boldness. The kickoff authorised volleyball game game match was play on July 7th, 1896 at capital of Illinois College, MA. People loved the sport, so right away it was spread crosswise the country, and was compete in most YMCAs.The jump dimensions of volleyball were very simple. The sign g overns by William G. Mo rgan required a net which was six feet and six inches risque (which was the size of an average person back hence). The court, overly made up by William G. Morgan, was 25 feet by 50 feet in size. An some other formula was that you could have as many players as you wanted on each boldness. The official weight of the volleyball was no less than nine ounces, nevertheless no more than twelve ounces (it was made go forth of the bladder from a Basketball). Over clock, most of these dimensions were changed to make the more appropriate sport called, volleyball game.There were several original play predominates designed for volleyball. One of the first determines was that the game consisted of nine innings. Depending on the number of players on each squad,the team would have one practise per player. After each team members serve was over, the inning would be over. The player serving continued to serve until he missed the serve or his team failed to return the ball to the other s ide of the net. You could unaccompanied report when your team had the serve. A nonher rule was, if the ball hit the net, it was called a net ball, and counted as a period for the oppose team. If the ball was served into the net, it would be called a dead ball, and would count as a trial. The next rule was if a player touched the net, it would be called a net, and would result in a point for the other team. If you caught or held the ball for a couple of succors, it would be called a carry, and would withal result in a point for the other team.In 1896, (a year after the institution of Mintonette) a man by the name of Dr. Alfred T. Halstead approached William G. Morgan at the first battle array game. He told him that a better, or a more appropriate name for the sport should be Volley bunch. William the liked the idea, and the name stuck. In 1952, the name was officially changed, by combining the words Volley, and Ball, and making its new name, Volleyball. To this day the sport still has the alike(p) name.Over the years, volleyball has changed tremendously. As you know, zip fastener stays the said(prenominal) anymore. closely anyways, the court size was changed to 60 feet by 30 feet. The net was also changed too, except this time, there was a size for a womens net and a mens net. The womens net was seven feet and quartette inches, while the mens net was seven feet and eleven inches. Also, the rule about(predicate) having as many players on the court was changed to six players per side (no more or no less). The balls official size stayed with the identical criteria, but mainly, it was about ten ounces. These dimensions will stay the same for a while, but some may be tweaked up a bit as the years go by. As I said, nothing can be perfect there is always room for a change.Just as they did for the dimensions, they also revised some playing rules. They got rid of the nine innings, and sooner, they changed it to three out of five, games to fifteen. Also, you could still only score on your serve, but you had as many serves as you wanted. Another rule was that you could no longer hit the ball as many quantify as you wanted. Instead, you only could have three contacts per side, and a player could only contact the ball once, or it would result in a misdemeanor called the two hits violation. The last rule added was the under the net rule if a player stepped over the line in the middle, (dividing the two teams) then it would result as a violation, and a point would be awarded to the contend team.As volleyball began to spread about the world, there was a buckram love for the sport, and some people wanted to bring the sport to the beach. rim volleyball was founded in the 1920s in Santa Monica, CA. It was at first played as just a recreational sport, where people could play for fun. It was played only with two people on the court, and the rules were slightly different than interior(prenominal)(prenominal) volleyball. It became a co mpetitive sport in California in 1947. In the sport you had to communicate and move very swiftly in show to do strong. It was a great activity to play at the beach, and many people thought it was one of the coolest sports ever to be invented. Still it was much the same sport as indoor(prenominal) volleyball the only conflict was that it was played on sand, and not on solid ground.Now for the dimensions of margin Volleyball (which be completely different than indoor volleyball). The court is somewhat 26 feet by 52 feet long. The net on the other hand, is the same criteria as indoor volleyball, except both men and womens nets are lowered by an inch, due to the uneven sand. Which means a womens net would be seven feet and three inches, andthe mens would be seven feet and ten inches high. Also, the outdoor volleyball is about an inch wider than an indoor ball, but it is lighter by about two ounces (which makes it easier for the ball to suffice up by the players). One completely different dimension from indoor volleyball is (not counting the court), there needs to be at to the lowest degree(prenominal) three and one fourth feet for playing space.In beach volleyball the games were still the same as indoor Three out of five, and games to fifteen. Also in beach, you could still only score when your team had the serve, which was called side out volleyball. Another rule was that you could not set the ball over the net, unless if you were square to where the ball was going to land. As for the under the net call, in beach, it was only called if you went under the net and interfered with another player (in other words, you got in the players way). Some of these rules, just like indoor, still will be changing to this day.In 1942, volleyball was introduced into the Olympics, but only as an exhibition sport. It in a flash was loved by all the fans, and many different countries started to develop their take in teams. Finally, in the 1964 Tokyo Olympic Games, voll eyball became an official sport in the Olympics. It was sponsored strongly by the International Olympic Committee (IOC). Beach volleyball would later on join the Olympics as well.Soon, beach volleyball took on a life of its own. In 1992, it was introduced into the Olympics as an exhibition sport. Also, just like indoor volleyball, the fans loved it, and many other countries developed teams as well too. Right away, in the 1996 Atlanta Olympic Games, beach volleyball became an official Olympic sport. Also, to this day, beach volleyball is thought to be the hottest ticket in the Olympics.Over the years, there have been many volleyball/beach volleyball leagues. Most of them have recently started over this century. Some examples are AVP, FIVBA, USVBA, subalternOlympics, and AAU. These leagues are mostly for professionals. Like AVP, which is basically the NBA for basketball players, but instead for beach volleyball players. Also, the USVBA stands for United States Volleyball Association, which is basically our U.S. Olympic indoor volleyball team.Over the years so many of the rules have changed, and actually, today, they are still being changed. One major change was the introduction of the libero. It was introduced in 1998. A libero is a player that wears a different color habilitate than the rest of the team, and they are basically defensive specialists. At any time during the game, if anyone needed to be taken out of the back row, they could be switched with the libero, but it would not count as a substitution. The only twist was that the libero was not allowed to play in the front row. One other rule that was switched was the side out rule, the rule was changed so that you dont have to provide the point on your serve, but you could also get a point on the opposing teams serve. Lastly, the games were changed to three out of five, games to twenty-five. In beach volleyball, the games were also three out of five, but the games were to twenty-one.In worldwide popula rity, volleyball is the second most popular sport in the world, the first being soccer. With about 46 million Americans that play, and over 800 million people that play around the world, it is obvious that volleyball touches lives. Volleyball has definitely grown to be the outmatch team sport there will ever be. The reason for this is because there cannot just be one star player on the team but, there has to be at least three contacts from at least two different players.ReferencesCrisfield, Deborah, and John J.

Characteristics Of Vapour Compression Refrigeration Cycles Engineering Essay
Characteristics Of Vapour crush Refrigeration Cycles Engineering EssayThis intent is a study on a performance of a dehydration condensate Refrigeration establishment VCRC. The performance of this shell of infrigidation agreement is being investigated by development different type of elaboration valves or to a fault know as throttling valves. I am victimization three types of valves upon conducting this study which atomic number 18 thermostatic expansion valve, capillary subway system expansion valve and constant- shove level expansion valve. Performance of infrigidation systems go away be investigated on 2 kind of surrounding which argon closed and open surrounding. A light bulb volition act as a modify hinderance which willing increase the ingress temperature of commit on e drying upation. This nominate also discuss about the ideal application program of each type of expansion valves. Which mean, where, when and what application the three types of expansion val ves should be use for a better result.Refrigeration is the action of alter, and in practices this waits removal of light and discarding it at superiorer temperature. Therefore, refrigeration is a science of moving alter from pitiable temperature region to the high temperature region.Refrigeration can be defined as a process of achieving and maintaining a temperature be humble that of the surroundings, with the aim to cool about product or space to the demand temperature. The most important applications of refrigeration are the preservation of perishable food products. Refrigeration systems also apply for providing thermal comfort to gentlemans gentleman beings by utilise fashion conditioning. rail line Conditioning refers to the treatment of straining so as to simultaneously reserve its temperature, moisture content, cleanliness, odor and circulation, as required by occupants, a process, or products in the space. The subject of refrigeration and air conditioning has e volved out of human select for food and comfort, and its history dates back to centuries.In refrigeration system, awake must be re locomote from the space area specific eachy the goods or matter we need to cool and released to the environment. Nature of heat movement is, heat always moves from the hotter to the colder space. To transfer heat from hot region to cold region, limited device is required. The device is called icebox. Refrigerator is a cyclic device and it is employ a fluid called cold as a working fluid.As known there are two common methods for refrigeration which are natural and mechanical. In natural refrigeration, ice is employ to generate a circulation of air around the blocks of ice. Therefore some of the heat from the circulating air is transferred to the ice so chill the air. This method particularly used in air conditioning application. As in mechanical refrigeration, refrigerating is used as a working fluid. Refrigerant is a substance that is adequate to(p) to transfer heat that it absorbs at low temperatures and pressures to a condensing medium. Refrigerator is an ex angstrom unitle of mechanical refrigeration.In a refrigerator, coolant is cooled in a electrical ability from there it flow to the evaporator, where air is cooled by contact with the c oil color. picture specimen of Refrigerator 2006 Publications International, Ltd.Types of refrigeration circle evaporation Compression Refrigeration SystemVapor compression refrigeration system is the most common refrigeration system used nowadays. In vapor compression refrigeration cycle (VCRC), there are four major thermal process matter place which is expansion, evaporation, compression and condensation. In all practical applications, the actual VCRC is land than the ideal cycle. This caused by several factors such(prenominal) as friction losses, heat exchanges amid parts on the system and pressure overtops in suck and discharge lines.http//t2.gstatic.com/ emblems?q=tbnA Nd9GcT-X7cy0Nn5FpUh23SVRaPzAFG_o0lp2WxOEMmReUZSPjiYERUt=1usg=__BGAiwbpSspuI0lSI-ZibGb3mh0Q=Figure exclusive demo VCRC The Full wiki/ refrigeration cycle found on Figure 2, compression process is done on compressor followed by condensation process on condenser, expansion process on expansion valve and lastly evaporation process on evaporator.Compression carry out on CompressorLow-pressure vapor of refrigerant enters the compressor and thence being compressed and moved to condenser as a high-pressure vapor (superheated).Condensation Process on CondenserThe superheated vapor of refrigerant is then travels by means of the condenserwhich first cools and terminates the superheat and then condenses the vapor refrigerant into a liquid refrigerant by removing additional heat at constant pressure and temperature. intricacy Process on expansion ValveThe liquid refrigerant is then goes through with(predicate) theexpansion valvewhich is also known as throttling valve where its pressure wi ll abruptly decreases, causingflash evaporationand auto-refrigeration of, typically, less than half of the liquid. By undergoing expansion process, mixture of liquid and vapor refrigerant is produced at low temperature and pressure.Evaporation Process on EvaporatorThe cold liquid-vapor refrigerant is then travels through the evaporator coil or tubes and it is completely vaporized by cooling the warmly air (from the space being preserve) and being blown by a fan across the evaporator coil or tubes. The resulting refrigerant vapor returns to the compressor inlet to complete the thermodynamic cycle.Vapor compression refrigeration system using high-grade energy such as mechanical work. It has more than affray and wear is possible to occur in the compressor since moving parts is put there. Coefficient of performance, COP of VCRC will decrease if the pressure of the evaporator decreases. Performance of VCRC is adversely alter at partial load.Vapor Absorption Refrigeration SystemVapo r Absorption Refrigeration Systemuses a heat source such as solar and kerosene-fueled flame to provide the energy needed to impel the cooling system. Vapor submergence Refrigeration system is a favorite alternative to repaircompressor refrigeratorswhere electricity is unreliable, costly, or unavailable, where noise from the compressor is problematic, or where superfluity heat is available such as from turbine vanquish or industrial processes. Absorption refrigerators powered by heat from thecombustionofliquefied vegetable oil botchare often used for food storage inrecreational vehicles.There are two type of vapor absorption refrigeration system that is single- order and double effect. Single-effect absorption system is using neither ammonia or peeing while double-effect absorption system uses atomic number 3 cliche or water supply.Since the presence of ammonia or lithium bromide directly into a confined space which is full of human is dangerous, vapor absorption system whi ch used this material should be placed away the realiseing to be cooled. However, vapor absorption that using ammonia or lithium bromide is not practical to be used on a building since it is impossible to pipe this material into the building. Therefore all absorption cycle equipment is then designed to chill water which is then piped into the building.The chilled water is piped through to fan coil units in each of the instruct spaces. The application of vapor absorption system using water is indeed well suited to multiple room systems or large spaces requiring air conditioning. This is because absorption chillers are a well-established technology that can offer significant advantages over schematic, automatically goaded, vapor compression chillers.Absorption cycle is using a fluid pair rather than using a mechanically driven or an electrically powered compressor to be function. The absorption cooling cycle is driven by the heat source, such as accelerator pedal burner, trav el or hot water. This heat source is used to boil and drive the refrigerant out of the refrigerant/absorbent mixture. This mixture is commonly termed solution.The refrigerant is then going through a condenser to remove the latent heat of condensation, thus returning the refrigerant into liquid form. The refrigerant is then passed to the evaporator where evaporation process draws heat from the recirculating chilled water. The resulting vapor from the evaporator is attracted and absorbed by the absorbent solution to complete the cycle. In effect, the mechanical compressor of a conventional vapor compression cycle has been substituted with a chemical pump driven by heat.http//www.acr-news.com/news/images/651_2.jpgFigure Single Effect Absorption modify ACR News locomote pip-squeak Refrigeration systemSteam Jet Refrigeration system is using the principle of liquids flashing under void in a chamber. If the flash vapor removed from the chamber, the liquid will cool to the required temperature. In practice, more than one cooling stage is usually present. Steam Jet Refrigeration system will move more economical when both go and cooling water is promptly available. Steam thousand refrigeration system working start with the steamerer passed through avacuum ejectorof high talent to exhaust a separate, closed vessel which forms part of a cooling water move. The partial vacuum in the vessel causes some of the water to evaporate, thus giving up heat throughevaporative cooling. The chilled water is wield through the circuit to air coolers, while the evaporated water from the ejector is vulcanised in separatecondensersand returned to the cooling circuit.Insteam jet refrigeration systems, water can be used as the refrigerant. Water is abruptly safe for human. These kinds of systems were applied successfully to refrigeration in the early eld of century. At low temperatures the saturation pressures are low (0.008129 bar at 4C) and the specific volumes are high (157.3 m3/kg at 4C). The temperatures that can be attained using water as a refrigerant are not low enough for most refrigeration applications scarcely are in the range which may satisfy air conditioning, cooling, or chilling requirements. These systems also used in some chemical industries for several processes, such as the removal of paraffin wax from lubricating oils. The application of steam jet refrigeration system also including cooling a hot corrosive liquid efficiently to any desired temperature and the cooling of fruit juices instantaneously.Note that a steam jet refrigeration system is not suitable to be used when the required temperatures are below 5C.Steam jet refrigeration systems use steam ejectors to reduce the pressure in a tank containing the return water from a chilled water system. The steam jet ejector utilizes the energy of a fast-moving jet of steam to capture the flash tank vapor and compress it. Flashing a portion of the water in the tank reduces the liquid temperature. High-pressure steam expands while flowing through the nozzle 1. The expansion causes a drop in pressure and an enormous increase in velocity. Due to the high velocity, flash vapor from the tank is drawn into the swiftly moving steam and the mixture enters the diffuser. The velocity is gradually reduced in the diffuser but the pressure of the steam at the condenser is increased 5-10 times more than that at the entrance of the diffuser (e.g. from 0.01 bar to 0.07 bar).The main advantages of this system are the utilization of mostly low-grade energy and relatively small amounts of sleep together work. Using Steam Jet refrigeration system will required negligible maintenance and a plant can be fabricate in any suitable material of construction. In steam jet refrigeration system, there is no moving part involved.http//www.siit.tu.ac.th/image/4ref.jpgFigure Steam Jet Refrigeration System Sirindhorn International Institute of Technology, Thammasat University thermoelectrica l Refrigeration SystemAn effect of refrigeration can also be achieved without using any moving parts. This is done by simply spill a small stream through a closed circuit which is made up from two variant metals. This type of effect is called the Peltier effect, and a refrigerator which is works using this kind of principle is called a thermoelectric refrigerator.The thermoelectric device is like the conventional thermocouple. It is using two dissimilar materials as a medium to transfer heat from one another. In a thermoelectric refrigerator, there are two pairing between the two different metals used. One junction is placed in the preserve space and the other one is placed in the ambient surrounding. The temperature of the junction which is located in the refrigerated space will decrease when the current passed through and create a potential difference. An opposite effect will occur on the other junction.Under steady-state drag conditions, heat is transferred from the refrige rated space to the cold junction. The other junction will be at a temperature above the ambient, and heat will be transferred from the junction to the surroundings.http//china-heatpipe.net/up_files/image/2008-4-24/826639119.jpgFigure Thermoelectric Refrigeration EffectThe thermoelectric refrigeration effect are too expensive for a normal domestic and commercial-grade applications which are run only on using a regular household current. This concept normally suited to recreational applications due to the clog of thermoelectric refrigerator which is light, compact and it is also insensitive to motion or tilting. This type of refrigerator also has no moving parts, and can prevail directly from 12-volt batteries.Using thermoelectric refrigerator will give a advantages to the food and beverages.

There are two main functions of compressors in the refrigeration cycle. The first one is to pump the refrigerant vapour from the evaporator so that the desired temperature and pressure can be maintained in the evaporator. The second function is to increase the pressure of the refrigerant vapour through the process of compression, and simultaneously increase the temperature of the refrigerant vapour. Therefore the pressure will change and make the superheated refrigerant flows through the systems.Compressor also known as the heart of the vapour compression refrigeration system because it is supplied energies to run the system. Compressor can be divided into two main categories which are shift compressors and dynamics compressors. Both displacement and dynamics compressors can be hermetic, articulated lorry hermetic or open types. Both compressors also pumps refrigerant passim the systems and produce substantial increase in th e pressure of the refrigerant.Displacement CompressorsThese types of compressors used a shaft work to increase the refrigerant pressure by reducing the compression volume in the chamber.

Analysis of Mental Illness via Girl, Interrupted (1999)
Analysis of Mental Illness via Girl, Interrupted (1999)GIRL, INTERRUPTED 1 launchIn the movie, Susanna (Winona Ryder) is diagnosed with Borderline nature Disorder. Susanna bonds with a few different patients, including Lisa (Angelina Jolie) with sociopathic personality disorder, Daisy Bulimia, Georgina pathological liar and Janet as Anorexic. Susanna starts to work harder with her specialist (Vanessa Redgrave) and the health check conjunction on the ward (Whoopi Goldberg). Girl, Interrupted was focused around the arrangement of memoirs of Susanna Kaysen, who truly did put in eighteen months a Psychiatric hospital (Mangold,1999).DSM V Diagnosis Criteria ConsistencyBorderline Personality Disorder is specify as a pervasive example of precariousness of interpersonal connections, psychogenic self-importance view, influences, and checked impulsivity, starting by ahead of schedule adulthood and gratuity in a mixed bag of conditions as showed by 5 or a greater amount of the follow ing (a) agitated endeavors to stay away from genuine or envisioned relinquishment,(b) An example of quicksilver(a) and extraordinary interpersonal connections portrayed by exc abeyance between extremes of admiration and cheapening, (c ) Personality aggravations especially and diligently instable mental self view or printing of self,(d) Impulsivity in no less than two zones that are possibly self harming,(e) Repetitive self-destructive conduct, signals, or dangers or self ruining conduct,(f) well(p) of view flimsiness because of a stamped reactivity of mind-set,(g)Chronic sentiments of va ejectcy,(h)Inappropriate, upright outrage or trouble controlling annoyance, and (i)Transparent, anxiety related jumpy ideation or serious dissociative indications (American Psychiatric Association,2013).The first criteria for BPD in Girl, Interrupted, was having self-destructive contemplations and doing things to help a conceivable suicide by endeavoring what Susanna called an impotent endeavo r to murder herself by taking a dose of aspirin with vodka. At the localise when the attendant attempted to hold her she says to be watchful in light of the occurrence that she has no bones in her grasp. Later on, the advisor asks her the means by which she got the container of Aspirin in the event that she had no bones in her grasp, she reacts aspect then theyd return (Mangold, 1999).The second criterion was incurring damage on the body by cutting or wounding. afterward she endeavored suicide, she was hurried to the crisis room, and the cam point changed from everyone wildly moving around to help to her wrists. She had wounds everywhere on her wrists and she keep telling the specialists she didnt have any bones in her grasp (Mangold, 1999).The troika criterion was Susannas endeavors to stay in the connections to abstain from feeling relinquished. At the amount of the film, she has a flashback of the illicit relationship she had with one of the instructors and with a fellow that she met aft(prenominal) her secondary school graduation. In both cases, she was having hazardous sex and staying in the connections with the goal that she matt-up needed and cherished, and not dismisses (Mangold, 1999).The fourth criteria was filling the blank that was generally felt by doing something she k immature wasnt correct yet provided for her rush. Susanna felt as though nothing was going how she needed it and she was the main private feeling that way. In the film, Susanna and Lisa, a young brothel keeper in the organization, chose to escape the mental home and go on an excursion to visit an alternate young chick that had been thither with them, Polly. Both of them k natural they could cause harm, yet the proceeded at any grade (Mangold, 1999).The fifth criterion was the point at which she encountered a shift in temperaments and felt uniform she had no feeling of herself whatsoever. Around the end of the film, there was a period Susanna was persuaded she wasnt going to improve and she got preventive over what Dr. wax light was letting her whop about her analysis. She proceeded and expressed how she couldnt have cared less and her new most loved word to portray herself was conflicted in light of the fact that she said it implied she couldnt have cared less any longer and she was going to do whatever she felt was correct (Mangold, 1999).We believe Susanna created these examples all the more in adulthood, yet everything originated from her youth occasions and they are reliably demonstrated in the motion picture concerning the indications of BPD in DSM V in any case, at one purpose of the film, her sweetheart comes and says that she is not insane and that she doesnt have a place there. She then says, Yet I attempted to execute myself. This shows how she has wrapped what had persistently been tossed at her. He tries to persuade her to flee with him to Canada, however shockingly she says she has companions here and that she herself is crazy . As per Comer, 2010, one of the characteristics of people experiencing BPD is that sentimental sentiments seeing someone are not generally shared. However in the motion picture, in spite of her refusal to flee with him, their shared adoration stays in place, in this manner demonstrating a conflict with the DSM-V as of right now (Mangold, 1999).After a long watchword with the get throughice head, Susanna gets more disappointed in view of what she says and takes a great deal of pills. The following morning she experiences difficulty awakening the superintendent acknowledges what has happened and completes her of quaint little inn her in the shower bath tub to wake her up. She has a fit, and gets to be exceptionally indiscreet. The superintendent tries to illuminate to her that she is not insane and that she is simply a lethargic, liberal young lady who is making herself insane (Mangold, 1999).The following morning Susanna finds that Daisy had submitted suicide by hanging hersel f and she calls the police and is taken again to the clinic while Lisa vanishes. At the clinic she has a discussion with her Doctor where she says that she wished she could have done something to help Daisy. She additionally states, Ill never know what its like to be her but I know what its like to want to die, how it hurts to s milliliter, how you try to fit in and you cant, how you hurt yourself on the outside and try to kill the thing on the inside (Mangold, 1999).There are a few distinctive emplacements on how an individual like Susanna could have created BPD. One view that scholars have, is that an early absence of acknowledgement by parents may prompt a loss of reward toward oneself, expanded reliance and a failure to adapt to division (Comer, 2010). In the motion picture, Susannas mother made a remark on when Susanna was an infant, she was transforming her table napkin and she turned around for a part second and that was when Susanna moved off the quaint little inn her l eg. She said the specialist place Susanna in a full body cast and her guardians went on a 4,000 mile outing with Susanna locked in the rearward sitting arrangement in the body cast (Mangold, 1999).Cultural DifferencesIn a collectivist society like Sri Lanka, close family relatives would be exceedingly concerned if an individual showed such feelings or practices. They would be extremely terrified and attempt to do whatever they can, mental strain to help them. It would not be a theme that would be talked among severally other individual, presumably just close relatives and companions. Once an individual has been diagnosed and at last cured, the enduring impression would not be of the said individual creation alone recouped. They would presumably still expect or mean at the once again of their brain that they are not totally cured or may tend to backslide. Notwithstanding they would at present be extremely steady as it is in their tendency to be so. These relatives and family wou ld likewise feel that an individual being diagnosed with a certain tell apart is because of the Karma which is the where their circumstance is ascribed to sins of the past births.Some parents of family members are regularly embarrassed to give way that their youngster is having BPD disorder. They attempt to lock their youngsters in a room in order to prevent embarrassment from the society. In the event that the kid does not so much succeed then the youngster is censured, debased or rebuffed, which may influence the kids self regard and trust in a radical manner. One of the principle purposes behind this is on the grounds that the absence of mindfulness about the issue accordingly there is a probability, where the perspective towards the kids and the issue of BPD may slowly change in the promising new years.ConclusionTo sum up, the movie indicates how the emotional sickness had a long effect on Susanna as it demonstrates how she would holler insanely in the shadow and be extremel y befuddled since she didnt recognize what wasnt right with her or felt caught on the grounds that she felt that nothing really wasnt right with her (Mangold, 1999). We in person think she would have gotten better if she was simply at home, while being stipulation personal treatment and care without confining her to a setting that induced, provoked or aggravated her disorder or she could have been given the dialectical behavior therapy which most clinical today utilize this therapy method.ReferencesAmerican Psychiatric Association.

Slowing Down the Speed of Light
Slowing Down the Speed of LightSTOPPING LIGHT INITS TRACKSNoorul Husna Binti Safian SauriAbstractIntroductionThe fact that speed of let down which is very fast(a) plenty be delayed down and stopped when there is change in refractive indicator. Stopped inflame achieved when the opthalmic twinklings argon trapped in some material such as in the taste which fuddle been done by G. Heinze et al.1. In that try out, the optical pulses was stopped in cooled Pr3+Y2SiO5 watch crystal up to 20s. Then unwind get out place be obtained by measured the decrease in base velocity. A.V Turukhin et al.2 done the experiment to observed the ultra ho-hum nimbleness. As a result from their experiment, a 45ms-1 speed of light were observed.The group velocity, is defined as vg(w) = c / n(w) and from the equation ng(w) = n(w) + w dn (w)/dw , it showed the dense light can be obtained from the variation of refractive index and the statistical distribution of the material. Further more, wh en , the group velocity can be highly reduced in material. So in locate to achieve the dimmed light, material with high(pre nary(prenominal)nal) dispersal is needed. However, in this situation a strong absorptions draw engender a big obstacle. It is because of the fact that higher dispersion gives a higher absorption and lead to a bad data transmission.Technique of Electromagnetically bring on Transp bency (EIT) introduced by researchers give the best solution for the strong absorptions although the EIT does non give 100% transmission. At the kindred conviction, EIT give additional advantages in order to slowed down and stopped the fast speed optical pulses.A solid- call down average is more p tintred in many applications of slow light because it has special properties. In solid- posit strong point, jotic diffusion is non being present, so it allow longer times for optical pulses storage. The slow light techniques play important role in numerous applications for o bject lesson in optical- conversation schema.Theoretical backgroundThe condition of vg Where E is voltaic field and is angular oftenness propagating through a forte. Then the grade of this wave is given by The points of constant phase will play in a velocity ofwhere k is a wavenumber. Then utilize the relation of the phase velocity become. n from the equation is refer to a refrective index and c is the velocity of light in a vacuum. When the field is not considered as monochromatic, that velocity is defined as a group velocity and this velocity shows the gene ration rate of changes in amplitude. Mathematically, group velocity is given by Group velocity besides can be defined as velocity at which elan vital or information is transmitted along a wave. Noticed that group index isthenFrom equation (6), the group index depends on dispersion and slow light can be obtained by making the large.Professor Jakob Khanin and Olga Kocharovskaya were the number 1 physicists that int roduced the theory of EIT. EIT is a phenomenon of quantum optics which permits an mirky medium to be transp arent to the optical light wave while still keeping the strong dispersion needed to generate the slow light. base on Figure 2, when a first light dick is applied to the mirky medium, the light beam is completely absorbed. Then, after a second light is applied to the opaque medium suddenly the medium become transparent.Figure 1 notification when the work beam is off and onThe blood corpuscles experience a free process. When light beam comes in which it resonant with the frequence of the transitions, the atoms will raise up to the higher energy level. This situation describes the normal absorption of light. Then, without any outside(a) radiation, the atom will decay spontaneously and end up in the lower realm. These process depend on the number density of photon,. At first, I study the deuce level nuclear system. From Einstein B coefficients, the transition probabili ty up from ground express 1 to excited state 2 is B12 and from the Einstein A coefficient, the spontaneous transition down from excited state 2 to ground state of 1 is A21. When the light is shining in the system, the number N1 of atom at the state 1 must be equal with the population N2 of atoms in the state 2. Then, the absorption in the system is said to be utter(a) which mean there is no absorption of light beam can be happen. This situation will not be able to kick in the phenomena of EIT from being happen. To make the two level system unbalance, another state is introduce by shining a second light. This is why third level nuclear system is used in the EIT.Figure 2 representation of absorption and spontaneous emissionFigure 3 illustrates the tierce level atomic system interact by a manipulate beam which is a strong optical field and a canvass beam which is a weak optical field. The tercet level system is also called a -system based on its shape. The atoms are consider to have a pair of lower energy states of 1 and 2. The see beam couples states 1 and 3 with frequency while the control beam couples states 2 and 3 with frequency . The two pathway put in and cancel each other and then clear a iniquity states polariton. Dark states means that there is no atoms will be call forth to the excited state and then vanish the absorption of light.Figure 3 representation of three level atomic systemThe expression of one-dimensional susceptibility spectrum explained the how the atomic ensemble respond to the strong resonant control beam and weak probe beam4. The expression is Where be similar to the slackening rate of the coherence, N is the total number of atoms in the sample, is the conflict amid the probe beam frequency and the frequency of the atomic transition (with = 0 show the frequency of the atom-field resonance), is the atom-field coupling constant, and lastly is the Rabi frequency of the control beam. Rabi frequency is defined as , where and E are correspond to the transition atomic number 42 and galvanic field of the control beam.From the susceptibility, the imaginary part,where is the transmission coefficient describes absorptive properties of the medium and L is the length of the medium. Then the real part of the susceptibility,showed the refractive index. Based on figure 4, the various wiggles refractive index whichis green gunstock showed the behaviour of nonlinear when detuning the frequency. The strength of the dispersion which relate to the slow light is determined by the gradient of the refractive index and at the selfsame(prenominal) time the penetrating EIT exhibit the strong nonlinear dispersive behaviour. The sharp peak of the transmission line showed the i rent EIT take place at exact resonance ( ). ). The exact resonance condition achieved when the frequency difference amid the two light beams accurately matches with the frequency separation amongst the two lower states of and .When t he exact resonance condition is not achieved, the interposition is not ideal the medium become absorbing5.Figure 5 represents the prolongation of light in the EIT medium. At the beginning, the light pulse is outside the medium and all the atoms are in the ground states( 1). The front edge of the light pulse then enters the medium and is quickly decelerated. The back edge of the light pulse propagates with vacuum speed c because it is still outside of the medium. Hence, upon incoming into the cell, the spatial extent of the light pulse is compressed by the ratio of , while its peak amplitude remains same. The energy of the light pulse is obviously much smaller when it is inside the medium. The photons are being expended to create the coherence between states of 1 and 2 , or in other words, to flip the atomic wrenchs, with the excess energy carried away by the control field. Then, the wave of flipped spins outright propagates together with the light pulse. The atoms are therefore strongly coupled to the photons which is in the light pulse, with an associated quasiparticle called a dark-state polarition6. The quasiparticle is a combination of photons and spins pique. The spatial extent increases again when the light pulse exits the medium and then the atoms return back to their sure ground state. However, a delayed of the whole light pulse occurred bywhere L is the length of the medium. In the dark-state polarition, when the control field is adiabatically switched off, the coupled excitation is converted into a pure atomic excitation, that is, the probe field is stopped7. Then, to restore the probe field, the control field is switched on. A storage time of more than a second were achieved in this way.Figure 4 Spectrum of transmission and refractive index corresponding to EIT. This figure is taken from abduce 4.. Figure 4 spatial compression occurred when the light beam enters the medium and at the same time the photons are changed into a atomic (spin excitation). This figure is taken from reference 5.In the situation when the decay rate between state and is negligible, the propagation of probe field can be describe by the electric field operator,where the sum is over the free-space of photonic modes with wave vectors k and bosonic operator 8. A collective atomic operators,averaged over small is used to describe the properties of the medium but at position z, macroscopic volumes containing particles 6.Specifically, the operator is used to describes the polarisation of atom oscillating at an optical frequency, whereas the operator decribes a low-frequency spin wave. Assumed that the control field is strong and it is treated classically. The atomic growth is conducted by a set of Heisenberg equation which is , where is represent the atom-field interaction Hamiltonian and 8. From these equations, the probe field is assuming to be weak and that and change in time slowly. To leading order in the probe field , find thatThe H eisenberg equation, draw the evolution of the probe field. A new quantum field which is a superposition principle of photonics and spin-wave components is introduced in order to attained the solution for the equations (15),(16) and (17).Furthermore, the new quantum field, must obeys the equation of motion,The equation (21) describes a shape-preserving propagation with velocity which is proportional to the magnitude of its photonic component.Moreover, EIT is also related to the Stark effect and Zeeman set up9. Stark effects is the splitting of energy level due to the present of electric field while Zeeman effects is the splitting of energy level due to the present of magnetic field. If a volume is considered to be filled by a hydrogen atom and a DC field is applied to the volume, the state will splits into three states with specific energies. By follow the notation ,the states degenerates while the states is generates which the state mixes with the states. The states are Di sscussionIn this section, I will disscuss about the implementation of EIT to observe the slow light and stopping.One of the technique used to induce transparency in opaque medium is Coherent population trapping or CPT. In CPT, the atoms are forced into a coherent superposition of Zeeman or hyperfine states that are strongly coupled to the light via Raman transition10. The definition of superposition state is the state which is stable against absorption from the radiation of electromagnetic field. Generally, CPT is more refer to the plan of two fields closely equal to the Rabi frequency. The experiment done by Alexander et al. 11 used the concept of CPT to observe the slow light in a hot rubidium atoms. The main idea in the experiment is to obtain the narrow EIT resonance.Currently, the quantum mechanics is used for a fundamental of communication and computation. To carry out these ideas, information should be encoded in delicate quantum states, uniform a single-photon states, and then manipulated without being destroyed. It is fact that photons are the fastest and be a simplest carriers of quantum information. However, they are not easy to localize and process.EIT has already had a large impact on the field of optical science. One of the possible application is used in optical buffering for the optical communication. From figure , there is an switch in optical router. The switch can only deal with one data packet at a time 10. So if two data packet arrive at the same time, the hitting of data packet will occur and the overall flow of the data packet will be slow down. Furthermore, the information carried by the two data packet will be loss. To avoid these problems, a slow light medium is activated in one of the branches in order to delay the velocity of data packet. As a result, the flow of information will be speed up because no collision between two data packet happened.References1 G. Heinze, a. Rudolf, F. Beil, and T.

Racism in the Movie, Crash :: Racism Crash Film Movie
All through time, the solid ground has been racist and intolerant of people different from themselves. Countless millions have suffered due to the bigotry of people that couldnt understand change or differences among wholeness another. there was a time when any soul that wasnt blue eyed and sandy haired in Germany, anyone with darker skin where immediately classed as inferior and not human. stock-still now, when you are not aware, racism is still a considerable problem. just now sometimes it isnt one person macrocosm racist against another, but preferably one person being racist against them self. The movie crash shows honest examples of how racism against oneself, caused by idolatry and misunderstanding, is just as malevolent and shame as racism against another person. Fear is what makes people act racist. Farhad is one of many examples in the movie of a person who recognizes his own hunt down and paralyzes himself through his own fear. Farhad believes that since he is Persian he is immediately being persecuted against and cheated. He flips out at the gun store when the owner was insult him which just furthers his fear of Americans. After the events on 9/11, which are cite a lot in the movie, Farhad thinks that anyone who is Middle Eastern isnt welcome in America. Even after the gun shop owner was rude his shop was destroyed by racist people who hated him. It is this same fear of being cheated because of his race that makes him very untrusting to people he doesnt know. He calls a lock smith to come fix his door because it wont lock. He immediately thinks that Daniel is trying to cheat him and steal money from him just because of his erstwhile(prenominal) endeavors.

AntigoneAntigone was the daughter of Oedipus. She had two brothers, Polyneices and Eteocles, and a sister Ismene. Oedipus had been the King of Thebes. However, he had killed his father and married his mother non knowing they were his parents. Oedipus was disgraced and had left the kingdom. His two intelligences were too young to rule, so Creon, their uncle served as prescript of Thebes. When Polyneices and Eteocles grew older they allowed their Uncle Creon to continue to rule because of the dishonor, which had been caused by their father. In time, each of the brothers wanted to rule Thebes. Arguments ensued. Polyneices mat he should be the ruler because he was the eldest. Eteocles, also wanted to rule, just now was forced to leave Thebes by his brother.Polyneices went to Argo and recruited an army against his brother and Thebes. During the battle Polyneices and Eteocles killed each other committing the sin of fratricide. afterwards the death of their brothers, Antigone and Ism ene were the only remaining members of the royal Oedipus family. Antigone was to marry Haemon, Creons son thus uniting both royal families. Creon gave Eteocles a heros funeral because he fought for Thebes. Polyneices was not to be given a proper funeral but left out in the open for animals to eat and carry off.Antigone felt she and Ismene had an obligation to bury Polyneices, as there were no longer either males alive in the family. ...

For a long time, my family and I attributed my brothers Cs in school and obvious inability to concentrate to laziness and a lack of motivation.

On the other hand, they had a very limited intellectual of mental illness. In particular, the concept of mental illness itself was not something they were terribly familiar with.

I didnt enjoy forcing myself t o concentrate, but I did it because I knew that I had to. In addition, my brother seemed perfectly capable of concentrating when he was playing soccer, watching the Discovery channel or playing painting games. In my mind, his problems appeared to be that he was spoiled and didnt like being told what to do. In addition, I think that ADHD gave everyone in my family the excuse that they needed.
