The Research Project - Assignment Example The rate of usage or even its rate of vacancy is a vital variable for the industry of hospitality. Just the way the owner of a company would wish that a productive tool is put into use as much as possible (unlike the paying of fixed costs whereas the company is not productive) so do hotels, restaurants and theme parks try to capitalize on the number of clients in all sectors. This resulted in the establishment of services with the objective of increasing the rate of usage offered by the consolidators of hotels. Information regarding the provided or needed items is brokered on the networks of business that are used by sellers and buyers. The objectives of this research are establishment of the evolution and growth of the industry of tourism, and its trends. Rationale The study of tourism as a field of academics is a recent matter, and has over the last few years seen rapid developments in the research focus together with methodological sophistication. The tracking of these changes off ers insights into the development and growth of research in the field, and citing the areas that require further focus. The industry of tourism and hospitality in the United Kingdom has come up as one of the major industries that drive the growth and development of the services sectors in the industry (Pechlaner et al., 2009). Tourism in the United Kingdom and the world as a whole has seen considerable development in the recent years and the nation has serious potential of becoming a major destination for tourists. The tourism industry of the country is doing well because of a rise in the number of tourists that come from abroad and greater number of the citizens that travel to the domestic destinations to view various attractions. Over the past few years, the actual growth has come from within the local sector since more than ten million people from within the country travel to see the attractions in a year. This consequently leads to a growth in the per capita income and improved lifestyles. This research therefore intends to establish the evolution and growth of the industry of tourism, and its trends. Research Ethics The researcher will apply Human Research Ethics for the use of questionnaires and semi-structured interviews. The major concern for this research will be the safety of the participants. This will be attained by assessing the risks and possible gains of the research and by using the information available for monitoring the progress of the project. Participants’ written approval will be sought and they will be informed that the information gathered for the research project will not be used for any other purpose than the intended. Care will also be taken to protect confidential and sensitive information and participants will be informed of any unanticipated findings that may affect them. Literature review According to Dann et al (2008), taking a look at different industries, we find that barriers to entry by the new entrants and competitiv e advantage between the existing players are very fundamental. Among some other things, the players in the industry of hospitality and tourism find benefits in the old classics (site), initial and continuing support on investment (which is reflected in the facilities material maintenance and the luxuries situated within), and specific themes of promotion arm that the

The Influence of Information Literacy on Scholarship, Practice, and Leadership Essay Example for Free

The Influence of Information Literacy on Scholarship, Practice, and Leadership Essay Information Literacy is a crucial portion of the scholarship, practice, and leadership model. Information Literacy that is utilized in a clinical setting by Physicians, Physician Assistants, and Nursing staff help to determine the type of care that is provided to patients. â€Å"Information competence is a basis for long-life learning competence and is necessary in any way of learning† (Tursheva, 2009, p. 127). As a scholar, practitioner, and leader, one must possess the knowledge and the ability to access various types of information. At the VA Hospital medical staff must all be knowledgeable of software that allows them to access the numerous amounts of patient data the assists them daily in performing their medical duties. Access to the internet or taking a trip to the local library is an everyday occurrence in the life of a medical student. Because of their career choice, they are constantly on a quest for new and vital information. We live in an information society. All individuals have the opportunity to enhance their way of thinking and change their lives personally or professionally. â€Å"Often information competence is defined as a skill of searching, evaluating, using, and distributing all kinds of information, which is developed during our whole life† (Tursheva, 2009, p. 127). Throughout hospitals in today’s society, there are medical libraries and journals available for medical students to use to broaden their knowledge as it relates to providing the proper treatment for their patients. Medical students serve as scholars. They continue to look for new and improved ways to enhance their knowledge in the medical field. The information they obtain is crucial for their development. Information literacy must continue throughout their careers. â€Å"Information literacy is not remedial, it is foundational† (Badke, 2009, p. 49). See more: how to write a scholarship essay for study abroad In a clinical setting, medical information changes on a daily basis. Physicians serve as practitioners in the medical community. They provide key information to medical students, residents, as well as nursing staff that help with their growth and development. Simons, Morgan, and Davidson (2012) stated, â€Å"in order for physicians to practice medicine successfully and become learners for life, they need to know how to search and manage the medical information they discover within their patient-centered context.† As a practitioner, physicians understand that these skills are necessary in order for their medical students and other medical staff becomes experts in their chosen field. As a scholar and leader in the area of medicine, it is imperative to understand how to work as a team to provide the best possible care to patients. â€Å"Educators are responding to complexities of today’s medical knowledge by developing educational programs based on current learning theories, such as enactivism, where learning takes place within teams that are actively engaged in clinical environments† (Davidson, Morgan, Simons, 2012, p. 291). This results in more patients that can place their trust in physicians and nurses who know how to work together as a team. Leaders provide an opportunity for students to grow. Upon entering college medical students are unaware of the importance of information literacy. They fail to understand the purpose that it will serve in their everyday lives. According to Russell (2009), â€Å"today’s students don’t have a clear understanding of what it means to obtain scholarly information that is useful† (p. 92). Staff physicians at the VA Hospital serve as leaders. They are solely responsible for the medical knowledge they provide medical students and residents. Because medical information is constantly changing, as leaders, they have to be prepared to adapt. â€Å"This learning must include access to evidence-based medical literature to make informed decisions, thus making information literacy a central activity of the team responsible for the care of patients† (Davidson, Morgan, Simons, 2012, p. 291). At the VA Hospital medical literature is readily available on all of the computers as well as a plethora of other information sources for the medical residents to make the best decisions regarding patient care. Information literacy provides the opportunity to access a variety of information utilizing different sources. This information provides needed knowledge to support ideas. Information literacy skills allow the adaptation to changing environments which serves as a support tool for better decision making in everyday life.

The Several Factors Which Are Behind The Cultural Penetration Cultural Studies Essay

The Several Factors Which Are Behind The Cultural Penetration Cultural Studies Essay This research paper explains the several factors which are behind the cultural penetration of west in Pakistani Elite society. It discusses how culture has become a bond that ties and differentiates the people of various society, region and community together. The research will give awareness to the people of our society about conserving Pakistani culture; about how it plays an important role in making them united and unified. It also identifies the different segments which are behind the increased globalization that has penetrated the western culture in Pakistani society, especially through media, lifestyle, language and family systems. KEYWORDS: Culture, Globalization. THE CULTURAL INCURSION OF WEST IN PAKISTANI ELITE SOCIETY CHAPTER 1 INTRODUCTION 1.1 Background The term culture has been used by various philosophers since decades. Raymond Williams claim it to be the most difficult word in English language The word culture has different meanings to evaluate human activity (Williams et al., 1976). Culture means to cultivate (Harper, 2008). Findley and Rothney describes it as, systems of symbols and meanings that even its creator contest, it lacks fix boundaries that are completely in flux and they interact and compete with one another (Findley and Rothney et al., 2006). All these authors describe it of being system of symbols that have blur boundaries. The bottom line is that how do we recognize them as those symbols? The answer to this is provided by Williams who say they culture is what is embedded in music, scriptures, literature, lifestyle, painting, theatres and other related things (Williams et al., 1976). These symbols are somehow alike in all the cultures. Due to rapid globalization and interaction of the past, these dimensions influen ce one culture or the other. This study will discuss the impact of western culture on Pakistani culture. Cultural penetration is the incorporation of other culture and language into ones own. Cultural penetration can take the form of general attitude as well. In this study, the focus is on the Western culture penetrating inside Pakistani Culture. Western cultures have been influencing other cultures worldwide. This is so because people equate Westernization (adoption of Western customs) with Modernization (adoption of scientific development). Westernization can be defined as a process whereby societies adopt the western culture in matters of trade, machinery, political affairs, finances, law, standard of living, diet, language, belief or morals. Westernization had an enveloping and fast influence across Pakistan in the last few centuries. This ever increasing era of globalization has increased the power of western culture in Pakistan, amongst the rich especially because of their easy contact with the western foodstuffs, media and other products. Many western food chains can be seen in the major cities of Pakistan. Western dress has become a symbol of status and honor among the youth and the business industry. Families no more share the family time together they use to in the past; rather they are more cautious about their privacy. Obsession with English is the major issue. People who read and write English very well can hardly understand Urdu. Even those who cannot speak English, try doing so as to look stylish. 1.2 Statement of the Problem The study identifies the factors behind the cultural penetration of West in Pakistani Elite society. It has been observed that people of Pakistani society feel pride in exercising westernized culture and tradition. They are being deviated from their own cultural norms and are adopting a more westernized approach. The main role played in increasing such behavior is because of the media, which is spreading the norms of the west. Pakistani societys lifestyles, family relations, dressing, education has changed drastically and is not what it used to be some years back. 1.3 Purpose of the Problem The study targets the characteristics which plays a significant role on the influence of western culture into Pakistani culture. 1.4 Research Question What are the main factors behind cultural penetration of west which are influencing Pakistani Elite society? 1.5 Justification of the problem The study can give awareness to the people of our society about conserving Pakistani culture; about how it plays an important role in making them united and unified. It can help people to understand the urgency to preserve Pakistani culture by providing a documented form of material that highlights the good and bad effects of adopting western culture. Fundamentally, culture makes use of artifacts and rituals to pass on notions of identity, which is observed to be missing in the Elite class of our Pakistani society. 1.6 Scope and Limitations Due to limited time span and shortage of research tools available the research was conducted only by the help of BBA and BSSS first and second year students who targeted the questionnaires on the elite class of Karachi. Chapter 2 Literature Review Culture is the awareness of traditions, ethics and way of life of a group of people. It is represented through various customs and traditions, arts, literature and costumes. Culture exists in different forms in different parts of the world. The surroundings greatly influence the lifestyle of people in that region, indirectly shaping cultures. (Manali Oak, Nov 15 2008). In Oaks et al., (2008) article she states that culture is the one common link that connects people of different religions or communities together. The traditions a group of people follow, the events they celebrate, their attire, food and above all the cultural beliefs they share, bring them together. Cultures are affected by people who accept its change and who resist them too. All these cultural ideas and beliefs for a matter of fact can change. Communal argument and the developing technologies give rise to changes within a society by altering social dynamics and advancing new cultural models or giving way to them. These social shifts are accompanied by ideological models and other cultural variations, for instance, people observing western cultures through media and then exercising them in their lives. Most prominently, western influence is observed to be seen in the Pakistani elite society. Their complete lifestyle and mentality is of the west and they, in no manner represent to be Pakistani. It can be seen clearly that how Pakistani elite class is discouraging their own culture to adopt modernization. (Dr Manzur Ejaz). The influence of west on the elite is basically being transferred through media. Media is playing a very vital role in portraying western culture, which is seemingly very attractive. Media is an agent of socio-political, cultural and economic change in our age and can strengthen or destabilize a society. The elite families of Pakistan can afford to live such a life which is full of westernized culture. They are moving away from their own culture (Muhammad Abbas, 2003). Muhammad Abbas et al., (2003) stated that its high time to fortify our socio-cultural practices. Our values are being invaded by the west through Cable TV. Media should lay their role in constructing faith and pride in our wonderful past, our values and the way of living. We have glorious norms and social strata which ought to be preserve, strengthen and encouraged. He emphasized on the fact that media can remove the negativity from Pakistani elite class because they are in transition. Their lifestyle is changing becau se of media and education and this particular change needs to smooth the progress in a positive manner. The elite families in Pakistan live a life closely similar to western families. for example the concept of family is different in west as compared to other Asian countries. Most western families consist of parents with average of 1-3 children. It is very common that parents are employed full time and are at work while their children are at school or daycare facility. Same is the case with Pakistani society. The children are now use to of living alone and independently without their parents at home. S, Venier (2004) stated that the American culture moves through every communicating medium. English as an international language for trade and politics is the strong tool for transmission of western culture. As English makes it way becoming a global language, it also becomes clear that although the forces driving the language and culture differ greatly but the two cannot be separated. Journalist S.M Hussain states that due to the increasing globalization; it is difficult to predict the impact of western culture on eastern cultures lifestyle in the future. Due to all of this Pakistanis have opened themselves up. Scholars in Pakistan admit in Daily Times Monitor (2008) that the extreme westernization has swept Pakistani culture. The extended family system, a feature of Pakistani cultural society has died away, especially amongst the elite classes who are exposed to American culture and now care more about their privacy. The young generation now seldom cares about their elders. Meal choices changed from Rice and Chapatti to KFC, McDonalds and Pizza Huts. Traditional drinks have switched to Coke and Pepsi. They feel pride in speaking English than Urdu. Dr. Ahmed Rashid Malik (2009) states that perhaps it is some colonial chip we are carrying on our shoulders, which focuses on us to acknowledge the western culture as cool and hip. Perhaps, we are still so much in awe of the white men that we cannot even see their faults and our own virtues. It is not as if it is just one area of the city that is affected by this, day by day it is seen that the entire place divided into little elite clutches of people is affected by this westernization. The influenced drive the latest cars, chatter away on their latest cell phones and wear designer Italian clothes, no matter if they do not even know how to pronounce their names properly. Hence we are a race of people with a culture that spans generations of grandeur, yet we want to throw that all away for just a small place in our minds that resides as pro-western elite. (Hussain, S.M) CHAPTER 3 3.1 FINDINGS AND ANALYSIS This study describes the important factors which are playing a significant role in bringing change to the mentality and lifestyle of the Pakistani elite society. 75 questionnaires were filled and analysis was concluded. The sample size was of 75 persons, out of which 34 were female, representing 45.3% and 41 male who are 54.7% of the total population. The age is dispersed from 18 to 62. Majority of respondents lie in the age group of 20 to 26. Respondents agreed that media is playing an important role in bringing western approaches. They justified that family relation is the segment of life which is affected the most by western culture. It has been proved that western incursion does exist in the Pakistani elite society. People of elite society are in many forms and segments of life adopting western ideology. There is a crisis of self identity prevailing within the people. It is revealed by the research that educational sector is the least affected segment of life by the western cultural penetration. The greatest change brought about by the western incursion is on the lifestyle of the elite Pakistani people. It is exposed after the research that family values are at stake because of the cultural penetration. Individual ambitions and benefits are more prioritized over mutual goals. Urdu being the national language is undermined and English is given more encouragement officially and unofficially. American lifestyle is commonly believed to be the most fascinating and appealing lifestyle, which is taken as most trendy and popular. 3.2 RECOMMENDATIONS AND SOLUTIONS As it is revealed to us that western cultural penetration exists in our society, there lie some responsibilities for us to undertake. Since it has rooted underneath the surfaces so immensely, it will not be easy to remove it from the society in a short span of time, for it requires much of hard work and struggle from everyone. Firstly, it is the job of the parents of our society to give correct guidance from the very beginning to their children so that they learn to appreciate their own culture. It is very important to differentiate between the cultures and to accept what is ours and like it from within. Secondly, all the educational institutions must also encourage their students to celebrate the national and traditional customs and festivals, rather than celebrating foreign ones. These institutions should also try to preserve the true value of Urdu as our national language. They must struggle to maintain the level of Urdu in the eyes of the students and to make them understand that it is good to speak English but Urdu must never be forgotten. Thirdly, the responsibility lies in the hands of each individual. Every one of us should encourage and appreciate our own Pakistani culture and should feel pride in doing so. We all should try to make people the importance of being under the label of ones own culture and country. As media is approached by everyone, it plays a very important role in portraying our culture. It should promote and preserve Pakistani culture in all the ways possible. Media should discourage the portrayal of those programs which in any way harms our culture. When lifestyle is considered, it is good to be advanced and technologically developed but we do not need to adopt those segments of lifestyle which deviate us from our culture and religion. Because one can only look best in exercising own culture and lifestyle. To cope up with the identity crisis, it is important to make the victims understand that following others just for the sake of fashion is no good to anyone. One should always be confident about his/her own talent and abilities and never under estimate oneself. 3.3 CONCLUSION It has been observed that the elite society in Pakistan are opposing their own culture and are more interested to follow western culture in their daily life. This can be called upon as western cultural penetration, which is slowly eroding Pakistani culture unnoticeably. This is referred as a problem because in the cycle of the society the new traditions are set from the upper social class and then followed by the lower social classes. Therefore it is very necessary that the elite class should be very conscious towards this social issue and takes care of what they think as culturally acceptable tradition.

Programmable Logic Controller System Plc

Programmable Logic Controller System Plc Two decades ago, machines were simple and work in factories was, for the most part, manual in nature. Machines were designed to be manually controlled. Today, if people look for around them will find many things have the control systems, which are necessary to organize the complex devices. The control system is of primary importance for devices and machines in factories, aircraft, cars, and even in some home devices. For this reason, life has become easier and production has dramatically advanced. Now, the control system is acting on behalf of humans, helping them for example to avoid risks in chemical factories, which can be extremely dangerous for humans. Today, it is difficult for people to avoid the use of control systems in the work place. Control systems control complex processes, which regulate the production in huge factories. Without automated control systems, factories face many problems, which would otherwise be very hard to find a solution to. With the beginning of the modern industries, the engineers needed systems to help them to accelerate production and to get high quality at a low cost. Electronic systems in the form of sensors and switches were invented to monitor and control manufacturing and reduce labor and production errors. Switches and sensors were needed to complement programming and hardware and to speed up the analysis of input data and obtain the results to assist the engineers in processing steps. The first system and software used in this area was the SCADA system. However, this system was complex and could not be linked with other monitoring systems. Hence, they invented the PLC, which in turn facilitated the process of programming. Also, it contained many possibilities including its ability to connect easily with other systems in production lines to assist in the development of the production process. PLC, which plays an essential part in the process of automation and control, is one of the most importa nt systems in many factory production lines, and it has more features than other systems. History of PLC Even after Programmable Logic Controllers (PLCs) were invented, a number of problems with relays remained to be worked out. Many enhancements occurred in the 1960s. In the 70s, they improved more. The ability to communicate between PLCs was added. This created a space between the controlling circuit and the machine it was controlling. Other problems had occurred in the 1980s, but they were controlled. Also during the 1980s, PLCs were made much smaller. Many more ways a PLC could be programmed were developed in the 90s. Overall, industries still use PLC in many ways and it is likely they will continue to be used for a long time to come. (Amunrud, 2002) Definition PLC stands for programmable logic controller, which is a device with many useful and helpful applications. PLCs are used in place of other electromechanical systems. In addition, PLCs can also control the systems of production, manufacturing, and semiconductor machines. PLCs can be designed to be used in extreme situations such as, high temperature, high humidity, and in conditions of extreme noise around very large machines .The data of PLCs can be very different. For example, PLCs in factories are all about speed and accuracy, so they depend on the ingredients and measures. However, PLCs used in traffic systems are all about organization (SIMATIC manual 2004). How PLC Works: A programmable logic controller (PLC) receives and collects input data from measurement devices, such as sensors and switches, then analyzes information of these input data at a high rate responding with program instructions as a process computer. After that, the PLC sends back the results as output data to the final devices, like motors, based on outcome estimated (Bern and Olsen, 2002). According to Bryan (1997), PLCs are capable of storing instructions, such as sequencing, timing, counting, arithmetic, data manipulation, and communication, to control industrial machines and processes. Reprogramming a PLC accepts changes on the functional operation of a machine system without main physical changes in the control or output system components or wiring (Cox, 2001). Therefore, a programmable logic controller needs an integrated system consisting of software and hardware. PLC hardware components A complete programmable logic controller (PLC), including all input/output (I/O) modules, is called a station. Every station has at least one module rack containing a power supply and a central processing unit module. Input/output modules create the link to the machine or plant. The parts of a station were illustrated below: Power supply (PS): it provides internal supply voltage, which is either 120V/220V AC, or 24V DC. A central processing unit (CPU): the CPU, which stores and processes the I/O data, is a memory and processer. Input and Output modules (I/O): they are receiving and sending data through network from the measurement devices to motors. Interface Module (IM): it connected the different racks with each other. A programming device: the two main things in the programming device are communicators and personal computers that help the programmers to create and insert the programs to the PLC. Human Machine Interface (HMI): it is a display and touch panel where operators can observe and manage the critical equipments. Those PLC components are working together to reach the objective of controlling the system .The input modules, or points, used by a PLC depends upon the types of input devices used. Some input modules or points react to digital inputs, also called separate inputs, which is either 0/1, on or off statements. Other modules or inputs react to analog signals. These analog signals represent machine or process conditions as a range of current values or voltage. The primary function of a PLC that has input circuitry is to cause these various switches to convert the signals and sensors into logical signals that can be used by the CPU. The CPU evaluates the status of inputs, outputs, and other variables as it executes a stored program. The CPU then sends signals to update the status of outputs. The output modules convert control signals from the CPU into either digital or analog values that can be used to control various output devices. The programming device is used to enter or change the PLC s program or to monitor or change stored values. Once entered and programmed, the associated variables are stored in the CPU. In addition to these basic elements, a PLC system may also include an operator interface device to simplify monitoring of the machine or process. Figure 2.0 below explains how the process of how PLCs connect in industry. Figure 2.0 this figure explained the whole system work. In addition to these basic elements, a PLC system may also include an operator machine interface device to simplify monitoring of the machine or process. Example shown below, pushbuttons (sensors) connected to PLC inputs is use connected to a PLC output through a motor starter (actuator). No programming device or operator interfaces are shown in figure 3.0. Figure 3.0: It show the input, CPU and output In previous figure 3.0 it describe the input signal which is came from pushbutton and received by CPU module in PLC rack which analyzing the data and send it to the motor starter then start and stop the motor depends on the type of signal. Sensors are devices that convert a physical condition into an electrical signal, such as a pushbutton that are connected to the input of a PLC. An electrical signal indicating the order (open or closed) of the pushbutton contacts is sent from the pushbutton to the PLC. Actuators that connected to the PLC output are devices that convert an electrical signal to a physical order from a controller, such as a PLC. A motor starter is one model of an actuator that regularly connected to a PLC output. Depending on the status of the PLC output, the motor starter either supply power to the motor or prevents power from flowing to the motor (figure 4.0). Figure 4.0: more description on PLC from discrete Input to discrete output In figure, 4.0 it is described in more details when the PLC rack received the signal which is came to input module then send the signal to CPU which analyze it and send the result to the output module. PLC Programming: Numerical systems are useful in most programs, as they are when used in conjunction with Programmable Logic Controllers to make programs. The basic function of programming devices is to show, store, and operate. The numerical system is the most important element of programming a Programmable Logic Controller. The number systems usually encountered while using programmable controllers are base 2, base 8, base 10, and base 16. These systems are called binary, octal, decimal, and hexadecimal, respectively. Using a binary numerical system, which uses 2 as the base, and only allows the use of digits 0 and 1 where there are no 2s, 3s , and so on, is used in programming. In devices such as computers and programmable logic controllers, the binary system is useful. It is an easier way to design programs to deal with machines that analyze between only two entries or numbers to start or stop. For example, 0 and 1 represent on and off, respectively. The octal system acts in place of the binary n umber system by using fewer digits. The octal system uses the number 8 as a base and only allows eight digits starting with 0 and ending with 7 (0, 1, 2, 3, 4, 5, 6, 7). Also, with other systems, using hexadecimal further reduces the number of digits in the programming language and coding system (Bryan, 1997). Leader logic is the main method of programming used in PLCs. This method is used to build the whole program by using the numerical system to save the program in the CPUs memories. In this section, many programs have their own language and PLCs have their own special language, which must be expanded and developed. Programming languages helps the programmer and user to build and enter a control program into PLCs. Types of PLC languages that are used in programming consist of three types: Leader, Boolean, and Grafcet. The Leader and Boolean actually work in the same way, but they have different ways in their insurrections, which are shown and how to enter into PLCs. The Grafcet language implements control instructions in a different manner, based on steps and actions in a graphic oriented program (Bryan, 1997). PLC programming languages are used in the SIMATIC programming languages to write a user program to control the machines or devices. Programmers have many choices of programming languages and programming methods in SIMATIC. The most useful programming language in PLCs is LAD (Ladder Logic Diagrams). Also programmers can resemble programs by using electronic circuit diagrams (Function Block Diagrams FBD). Those familiar with textual languages or coding languages can use and handle Statement List STL with many complex variables (SIMATIC, 2003). Programmable logic controllers have different languages that offer different advantages and benefits for the process engineers. Different languages in PLC applications help engineers in the complex projects that give the process engineers flexibility in determining which is the most appropriate language to use. The differences between languages in programmable logic controller are in the structure but not in the instruction. For example, LAD uses block symbols language, but STL uses coding language. Figure 5.0 below is helpful in describing the differences between the two languages (SIMATIC, 2003). Figure 5.0: it describe the differences between LAD, STL and FBD Figure 5.0 describes three different languages. The first row explains the LAD language. Element symbols, which are described NO contact, stand for normally open contact with the signal 1 (yes) if it is active and 0 (NO) if it is not active. The next symbol NC contact, stands for normally closed contact. In the second row, the FBD language blocks describe other kinds of language in same manner but in different shape. Normally open contact in FBD language appears as a box and it is possible to write the value inside the box. On other hand, normally closed contact is in the same shape of normally open contact but with a small circle by the side of input to express a closed state. STL language has a different formula but the same instruction coding system. In the development of programming, engineers can convert the program display from one language to the other to check and correct instructions. All subprograms and instructions in different languages for devices and machines could work together as one program to achieve the process needs (Berger, 2008). Advantages of programmable logic controller (PLC) PLC has many advantages that make it a unique process controller. The advantages are always increasing. Programmers, operators, and engineers prefer the PLCs over other control systems, because of their simplicity, security, and reliability. PLC Is Simple and Flexible No control systems are easy or simple, but PLCs have emerged as comparatively simple and easy to other leading process control systems. In PLC is easy to add or remove any ending device without affected the whole process. Also, PLC has the flexibility to monitor and correct the system anytime even though the plant On-line situation or Off-line situation (SIMATIC, 2003). PLC Is Distributed Allocated controlling system implicates many computers and stations on network occupied to gather. PLC is created to make allocated controlling system smooth with the networking faculty and equipments that are inseparably joined to it. PLC is considered the sender and receiver on writing network system files. Also, PLC is able to work with the hardware parts and the software side of the computer, including those operating systems Windows 95 and NT, the Macintosh, XP and Vista (SIMATIC, 2003). PLC Is Secure The security in PLC is excellent. It is one of the first control program that has the most powerful protection from risks, losing data and the damage to the users. Those features have made PLC a sophisticated and useful control program system. Comparing PLC with SCADA from the security side PLC has the greatest result (SIMATIC, 2003). PLC Is Reliable Both reliability and security are important to each control system. PLC is one example of those control systems, which have them. PLC affords multiple points of reliability measures, starting with PLC itself and ending with many of its features. For example, pointers and automatic type conversion are included in PLC . Before PLC is finished doing and start a program it has to check if there is any mistake that it can fix by itself or ask the user about it (SIMATIC, 2003). Conclusion Programmable logic controller (PLC) language has helped develop the control system, and it has become the most useful language. Programmable Logic Controllers have become the language that most companies and factories use. They supply and support engineers with what they need and they keep operators protected from hazardous machines. The potential of programmable logic controllers in controlling systems is almost limitless. Programmable logic controls have fed and supported control systems in many ways. Most process computers utilized in factories with humans have more advantages than disadvantages as a secure system when dealing with complex process. Programmable logic controllers have proven to be an effective and helpful tool in many industries in the past. With their many advantages, they will continue to be useful in the future as well.

A Holiday Deconstruction :: essays research papers

A Holiday Deconstruction By RA   Ã‚  Ã‚  Ã‚  Ã‚  Everyone looks forward to holiday entertainment. Jordan has faithfully kept the tradition of mounting a holiday show for the entertainment of the student body, staff, and students parents. Notice how à ¢Ã¢â€š ¬Ã…“communityà ¢Ã¢â€š ¬? does not follow à ¢Ã¢â€š ¬Ã…“staff.à ¢Ã¢â€š ¬?   Ã‚  Ã‚  Ã‚  Ã‚  Anyway, after watching the show A Holiday Celebration I was appalled by the misuse of Christmas themes. So many things were wrong with the show. First off, the Ghetto Holiday Skit: ità ¢Ã¢â€š ¬Ã¢â€ž ¢s starts off as a predictably funny opening between two half-witted burglars who take too long too enter the damn house, and when they do, they have the audacity to continue (discussing) or alluding the window. What completely destined a potentially comical skit was the sexual insinuation that shamelessly demoted those with an alternate lifestyle to objects of derision if anyone with a social conscious saw the skit; they had to notice the aforementioned.   Ã‚  Ã‚  Ã‚  Ã‚  Secondly, the Santa Claus bit: Okay, I will give you this: we all need comedy in our lives. However, do we need comedy at the expense of other? Ask yourself this, how did overweight people feel about being made fun of? à ¢Ã¢â€š ¬Ã…“Damn these childrenà ¢Ã¢â€š ¬? Do we need children to be damned more than they already are. I mean, what is wrong with this? We grow up believing St. Nick exists but do we need to also believe that he is a drunk who holds grudges against kids? Think about it.   Ã‚  Ã‚  Ã‚  Ã‚  Third, the models: lack of professionalism on their part. Who models their own style? (Own clothes) But hey, at least they incorporated à ¢Ã¢â€š ¬Ã…“bigà ¢Ã¢â€š ¬? people.   Ã‚  Ã‚  Ã‚  Ã‚  The two main problems with the show or any Jordan shows is the lack of diversity. Jordan is a tapestry of diverse cultures, yet only one is predominantly represented onstage. If youà ¢Ã¢â€š ¬Ã¢â€ž ¢re intelligent, you might figure which group of people! If we preach diversity, lets practice it, please. The other problem is the gospel singing.

polymers :: essays research papers

Cornstarch is an example of a polymer. Polymers are long strains of molecules that keep repeating and have different properties of the original single molecule group. A single section of a polymer is called a monomer. It resembles the simplest form of the repeating portion of the entire polymer. These polymers may get stretched when you make a mixture such as cornstarch and water. This mixture behaves a certain way. There are many theories on why this may occur. One theory is because the strands get tangled, making it hard for them to slide against each other. Stretched molecules would offer more resistance to movement, like the resistance of a stretched rubber band. However, this argument does explain why rapid motion (stirring, shaking, etc.) increases viscosity, which is the property of a fluid that offers resistance to flow. Cornstarch and water is a non-Newtonian, organic fluid. Fluids can fall under different sub groups. They are either Non-Newtonian or Newtonian. They can also be either organic or non organic. Non﷓Newtonian Fluids are a group of liquids that change viscosity when they are stirred, shaken, or otherwise agitated. Cornstarch and water acts differently depending on whether it is still or agitated. This kind of fluid is called a dilatant. It becomes more viscous (has a relatively high resistance to flow) when agitated or compressed. The viscosity of a non-Newtonian fluid is also dependant on temperature. Cornstarch would decrease in viscosity if put in a boiling pot (it would become thinner). Examples of Newtonian fluids include motor oils, mineral oils, gasoline, kerosene, and most salt solutions in water.   Ã‚  Ã‚  Ã‚  Ã‚   The most popular explanation for the behavior of cornstarch and water is that when sitting still, the tiny grains of starch are surrounded by water. The surface tension of the water keeps it from completely flowing out of the spaces between the grains. The lubrication of water allows the granules to move freely. However, if the movement is abrupt (shaking, stirring, poking, slapping, etc.) the water is squeezed out from between the granules and the friction between them increases dramatically.   Ã‚  Ã‚  Ã‚  Ã‚  Other examples of polymers are present in our everyday lives. Water-resistant paints and varnishes derive from a family of synthetic polymers called acrylics. Polystyrene foam, or styrafoam, is used when making cartons to protect eggs, or making packing peanuts to cushion fragile objects for shipping. It insulates, so people put drinks in foam cups and coolers to keep the warm ones warm and the cold ones cold.
