Open Communications Network With PLCs Assignment

Open Communications Network With PLCs - Assignment Example These levels of communication are either open or closed. Open communication technologies using programmable logic controllers are in some instances considered to be less secure since they are prone to interference by unauthorized individuals. However, they are proffered by several companies due to their low costs (Beach, 2008). There are several devices that enable data transmission using Programmable Logic Controllers. These encompass several gateways that are hosted in different operating system development environment. Open network communication getaways use the open Linux development environment together with certified hardware to ensure secure and efficient data transmission. Using these getaways, several interfaces are employed. These include universal serials Buses (USB’s), Serial ports, secure digits cards (SD cards) and Ethernet. Also, internal peripherals such as Global position System (GPS) receivers, and cellular modems maybe used. Programmable Logic Controllers networks are equipped with several options that are designed to meet specific communication and control requirements. Some of the typical options provided include peer-to-peer communications, host computer communications among others. The vendors of this PLC devices produce unique devices with unique networking capabilities (Irwin,

RIBA Essay Example | Topics and Well Written Essays - 5250 words

RIBA - Essay Example The RIBA plan of work is prepared by the Royal Institute of British Architects in conjunction with other stakeholders to provide a regulatory framework for practitioners in the building and construction industry (Cross, 2013). The RIBA plan of work is widely used in the UK as the official guideline and directive indicating the best practices in the industry (Farrelly, 2014). The plan of work has been extremely efficient such that it has been benchmarked by numerous countries worldwide, modeling their building and construction industry regulatory framework on RIBA’s. RIBA has continued to update its plan of work since 1963 as times and circumstances change (Hopkirk, 2014). The latest plan of work was prepared in 2013 and represented a paradigm shift from the previous one prepared in 2007. The stages of work have essentially remained the same only that they have been categorised and labeled differently (Architecture.com, 2014). Instead of the eleven stages that were explicated b y the tasks to be conducted, the new plan of work has eight stages and eight task bars under each stage indicating the tasks to be conducted.

Research PaperCultural Intersections - Essay Example Since the process if bettering oneself is just that - a choice, when the black sub group chooses to pursue another cultural path within the American culture, white America often shows little tolerance or understanding. For black America, the melting pot and land of opportunity images have never been allowed to become the cultural icons with which white American's co closely identify. The black experience of American culture did not begin with voluntary immigration in the pursuit of a better life. Black American's were forcibly taken from their homes and brought to America as slaves. Black American's, while no longer living as slaves, and living in a free country, still struggle to establish a distinctly American and successful identity. Their path was forced, not voluntary. Their emigration was from freedom to bondage, while white Americans, to a great extent, left religious and social bondage to establish freedom. From these two different paradigms, two different American cultures have emerged. At the seam where these cultures meet, friction and misunderstanding are the norm. As a result, a homogeneous America currently does not exist for either group, and both sub-cultures tend to carry a chip o n their shoulder, blaming the other as the source of the discord. For both of these cultures, the idea of choice should be taken into consideration so that the individuals can begin to move past their individual ideas of how America 'should' look. White Americans and black Americans each have made choices on how to perceive their country and culture. Each has come to an individual understanding based on their choices and personal experiences. Unfortunately, at the intersection of these two paradigms, the individuals often try to justify their perceptions as something bigger than choice. White America lifts up their own experience as 'how and what America is.' America is the melting pot, the land of opportunity, and any individual or people group that does not perceive it similarly is understood as attacking America. Black America similarly can understand the country as an oppressive culture, bent on taking from them their individuality and uniqueness as it tries to squeeze them into the white cultural mold. Working under this perception, black Ame ricans can easily turn aggressively hostile to the white paradigm, which leads to conflict, and disunity. Reike and Sillars, in their work on critical decision making (1993) address this phenomenon by accurately identifying it as the product of choice. They say that our individual belief systems are made up of two components, beliefs and values. Individuals settle on core values as both an individual and as a larger group. Often these values within a culture are similar, even though they are worked out in different ways. Americans as a group tend to hold the value of independence as a universal value. Individuality is also a shared cultural value. According to Reike and Sillars, built around these core values are individual belief systems which shape and affect our understandings of our values. Belief systems are most often learned behaviors. Belief systems are based on what is important to us, our values, but they also reflect our personal experiences, and our belief systems also shape our actions. We will rarely make decisions or choose a course of action which is in violation to our belief system, even if the belief system inaccurately reflects

Reasons for the Decline in Union Membership and Density in the 21st Research Paper

Reasons for the Decline in Union Membership and Density in the 21st Century - Research Paper Example Over the past decade, unions have used their political clout to advocate legislation and establish regulatory agencies that supersede entirely or greatly circumscribe the scope of collective bargaining on many issues of significance to employees. When deciding whether or not to form or join a union, workers balance the costs of doing so, such as union dues, against the expected benefits, such as better working conditions and pensions. While the costs of joining unions are seemingly unaffected by most labor legislation, the potential benefits of doing so decline. Because they are already buying labor protection and mandated fringe benefits with tax dollars, workers have less incentive to join unions. The political success of unions in the past has surely played some role in undermining their future prospects, as in the case of VBY union. It is no secret that labour unions have been declining in membership and influence for many years. The number of unionized workers in Europe was only 16.7 million in 1990, which is approximately 16 per cent of the workforce. This is less than one-half the per cent unionized in the mid-1950s. Some managers view the decline of unions with glee. To them unions are non-productive, combative adversaries interfering with the harmonious and efficient operation of the company. Some of them have adopted the idea that this is pay-back time for the punishment management suffered in the sixties and early seventies when rising wages, automatic cost of living adjustments, ever-increasing benefits, strikes, and Byzantine work rule arrangements seemingly were the rule.  

Breaching Experiment Research Paper Example | Topics and Well Written Essays - 1500 words

Breaching Experiment - Research Paper Example For this experiment, in which the student will assume the personality of a FaceBook creeper, the reaction to being a creeper is the most important point. If the social breach succeeds and social norms are compromised, how people react is evidence of mechanisms through which they attempt to combat the breach or make sense of the abnormal behavior (Garfinkel, 2011). Whereas it is expected that lighthearted breaches in the FaceBook creeper experiment will induce curiosity, confusion, and laughter, breaches of a more serious nature are expected to cause anger and anxiety. It was also expected that the experiment would show how uncomfortable people are about unexpected notification or information. The Facebook picture creeper experiment was chosen for this study, in which I had to go through the photo album of an acquaintance on Facebook and comment on about fifteen to twenty photos. These photos were supposed to be more than six months old and the comments were to be posted over a period of three days. In addition, the experiment required that only positive comments were written on the posts, such as â€Å"cute photo† and other positive comments. After posting, I was to check back to identify whether anyone else had commented on photo as a result of my posts and a description of the responses was to be made, as well as a description of how I felt about making these posts. For the experiment, I picked one of my friends from high school, whom I had not seen or talked to for some time and was not a friend on Facebook. I searched for her name on Facebook and identified her photo, after which I made a friend request that was accepted. Immediately after we became friends on the site, I commented on twenty of her photographs from her photo album and, as required by the experiment, I ensured that all my comments on the photos were positive. In the beginning, I commented on only a few photographs

The Basseri of Iran culture Research Paper Example | Topics and Well Written Essays - 2000 words

The Basseri of Iran culture - Research Paper Example The kinship factors include the patrilineal, the marriage and the divorce aspects of the Nomadic tribe of Basseri and the way it is different to the cultural values to the rest of the country. The social organizational factors is a combination of a number of factors that include the rite of passage in the nomadic society, the headmen that lead the tribe and the Khan who is usually a wealthy person having a number of followers of his own that makes him strong enough to head the society. Economic Organization Nomadism The Basseri Nomads of Iran are the tent-dwelling pastoralists who are under a chief and politically centralized. It is officially stated that the Basseri are Shitte Moslems but such a religious affiliation does not exist to a very big extent among these people. These people seem to be very uninterested in religion generally. The ritual activities of these people are very few as they offer no communal prayer and are more likely to ignore the Islamic feast days. Even the ho ly month of Ramadan seems to be a very unlikely proposition for most of the people. It is concluded that because of the migration that these people had to do early in their history, there was progressively built tension and excitement and most people were confused whether the economic activity was a religious one or not. These tribes responded more to the movement that was in a more dramatic form rather than considering the utilitarian aspects of the whole movement. There was highly complex essence of tribal organization in Iran that was centralized Uymaq system. The Uymaqs were not only the pastoral nomads but were a combination of three economic forms, the pastoral, the commercial and the agricultural. Importance of Livestock The individual households of the Basseri of Iran hold usually herd their animals together in one or even more than one flock of 400 to 600 animals. This figure limits the number of households that are grouped together. The members of the camp are usually are widely drawn from both consanguineal and affinal groups. Some of the members are not even the immediate groups of these people in the society. The shepherds are usually hired by the members of the camp for the service contracts of one year so that they can care for a single flock of 400 to 600 goats and sheep. For every ten lambs that are born in the spring, they receive one lamb for their work all the year. Even if they quit a bit earlier, there is no pro-rated agreement as the lambs have not been born yet. All of the households owns and milks its own animals separately even though they are gazed together. Also, different households pay, give food and other materials needed by the shepherds in their contribution depending on the number of animals that they own with the addition of the two assistants that the shepherd usually has. Environmental Adaptation The major concentrations of the population of the vertical nomads in Iran occur during the summer. The camps are usually composed of as many as fifty tents during that period of the year. However, during the winter migrations, the camps are composed of as many as twelve tents and as few as one tent. The camps are usually separated by an hour long walk from the neighboring camps and also the pasture areas. However, the visiting between people from one camp to the other and staying connected with each other is a regular activity of the nomads in Iran.

Importance of International Trade Essay Example for Free

Importance of International Trade Essay The buying and selling of goods and services across national borders is known as international trade. International trade is the backbone of our modern, commercial world, as producers in various nations try to profit from an expanded market, rather than be limited to selling within their own borders. There are many reasons that trade across national borders occurs, including lower production costs in one region versus another, specialized industries, lack or surplus of natural resources and consumer tastes. One of the most controversial components of international trade today is the lower production costs of developing nations. There is currently a great deal of concern over jobs being taken away from the United States, member countries of the European Union and other developed nations as countries such as China, Korea, India, Indonesia and others produce goods and services at much lower costs. Both the United States and the European Union have imposed severe restrictions on imports from Asian nations to try to stem this tide. Clearly, a company that can pay its workers the equivalent of dollars a day, as compared to dollars an hour, has a distinct selling advantage. Nevertheless, American and European consumers are only too happy to lower their costs of living by taking advantage of cheaper, imported goods. Even though many consumers prefer to buy less expensive goods, some international trade is fostered by a specialized industry that has developed due to national talent and/or tradition. Swiss watches, for example, will never be price-competitive with mass produced watches from Asia. Regardless, there is a strong market among certain consumer groups for the quality, endurance and even snob appeal that owning a Rolex, Patek-Philippe or Audemars Piguet offers. German cutlery, English bone China, Scottish wool, fine French silks such as Hermes and other such products always find their way onto the international trade scene because consumers in many parts of the world are willing to foster the importation o f these goods to satisfy their concept that certain countries are the best at making certain goods. One of the biggest components of international trade, both in terms of volume and value of goods is oil. Total net oil imports in 2005 are over 26 million barrels per day (U.S. Energy Information Administration figures) (Note: Imports include crude oil, natural gas liquids, and refined products.) At a recent  average of $50 per barrel, that translates to $1billion, three hundred million, PER DAY. The natural resources of a handful of nations, most notably the nations of OPEC, the Organization of Petroleum Exporting Countries, are swept onto the international trade scene in staggering numbers each day, and consumer nations continue to absorb this flow. Other natural resources contribute to the movement of international trade, but none to the extent of the oil trade. Diamonds from Africa, both for industrial and jewelry use, wheat and other agricultural products from the United States and Australia, coal and steel from Canada and Russia, all flow across borders from these nations that have the natural resources to the nations that lack them. Despite complaints about trade imbalances, effects on domestic economies, currency upheavals, and loss of jobs, the reality of goods and services continually crossing borders will not go away. International trade will continue to be the engine that runs most nations. Information is for educational and informational purposes only and is not be interpreted as financial advice.
