Range of semiconductor devices and circuits Coursework

Range of semiconductor devices and circuits - Coursework Example A good diode should posses forward to reverse resistance ratio of 10:1 with others with the ratio up to 100:1. If a diode is open, it will show infinite resistance in both directions. On the other hand, a shorted resistance will show low resistance in both directions. The procedure for testing the diode using an ohmmeter only is as illustrated in the following steps. 1. The Ohmmeter is configured to measure on the lowest range. If it’s a digital ohmmeter, a 2-kohm range or the nearest equivalent is used. 2. The ohmmeter leads are connected across the diode with the positive red probe on the P-material and the negative black probe on the N- material as shown in the diagram below. 3. The measured resistance of the diode is measured; Rf is recorded after which the setup is disconnected. 4. After the disconnection, the leads of the ohmmeter are reversed and connected in the reverse direction i.e. the positive red probe is connected to the N – material on the diode and the n egative black probe is connected to the P – material on the diode as indicated in the figure below. 5. The measured reverse resistance RR (reverse resistance is recorded) 6. The forward and the reverse resistance ratio is calculated as RR/RF 7. If the reverse resistance ratio is equal to one or very close to one, then the diode is faulty. In the same way the polarity of the diode can be identified. When the diode shows infinite resistance the material connecting to the positive red probe of the ohmmeter is the P – material of the diode. On the contrary, the part connected to the Negative black probe of the ohmmeter is the N – material of the Diode.

Gay and Lesbian Marriage Essay Example | Topics and Well Written Essays - 2000 words

Gay and Lesbian Marriage - Essay Example This is clearly a situation where, while actions are happening on the micro level of society, the response is being created by the macro level of society. Gidden's Theory of Structuration looks in detail at how all levels of society interact and help to create the responses of the other levels. Gidden's suggests that no social structure is permanent; rather it is built upon the actions of those who reside inside of it. While society can not be explained from the macro level, it can also not be explained without it. By reviewing the concept of gay/lesbian marriage from through Gidden's theory, a clearer view of society emerges. Gidden's argues that there is a duality to social structure. While it is created by those who live in it, they are also bound to follow its' rules (Fuchs 1). While it is clearly ever changing, there are also certain areas which remain static, based upon the culture that is being reviewed. Gay/lesbian marriage is an issue that is currently affecting all cultures, causing slow changes to the status quo. In European nations, gay marriage is slowly gaining in acceptance. However, it still meets with strong disapproval in the United States. A key difference between the two societies is the religious factor. While most European countries claim Christianity as their religion, there is also a certain lax feature about religion. It is accepted that a person may or may not be religious, and that therefore not all people should be bound by religious ideals. At the same time, the United States claims

Hume's analysis of the process by which we make causal judgments Essay - 1

Hume's analysis of the process by which we make causal judgments - Essay Example This paper is going to discuss Hume’s analysis of the process by which we make causal judgments. Causality can be defined as the relationship between an object and a fact; it is among the most recognized ideas that we have. Causality is involved in almost all undertakings or human way of thinking; it is assumed in every argument and sensible actions. It is considered a beneficial idea in all areas of philosophy including philosophy science from the time of ancient Greeks to present. Hume as a philosopher, he defines causality as something that clinches things together. Knowing what causes are assists us to know how minds might or might not relate to bodies, how bodies might approach to create changes in other bodies, how thoughts might or might not influence deeds and how free they might or might not work. Therefore, all human beings are naturally attributed to certain occurrences of causal actions upon others. This means that whenever there is change in something, there is a quality that disappears, and another one appears, and the source of these changes is cause. In other wo rds, for every quality produced as a result of change, there is a cause for that. Many changes occur due to the relation between change and cause. Hence, this natural acknowledgement of the association between cause and effect to occurrences is at the forefront of all the philosophical declaration and analysis. There are characteristics that help to differentiate the causal relations in the universe, which include non- anthropomorphic, uniformity and determinism. Non – anthropomorphic, causal relation means a name given to change, and that in causal correlation wishes, purpose and desires are never mentioned. Uniformity describes causal relations as unchanging habits between facts, on the other hand, determinism characteristics emphasize that there is a connection between a cause and an effect. Meaning causality is prejudiced by the presence of other

Case Analysis of CUP - Essay Example As an advisor to Derrick Westmuller, I would gladly advice him to use the CCC or Customer Care Center. A company won’t be able to function once the flow of the customer is not good. So it is just to protect the interest, satisfaction and happiness of the customer. With this great idea, many issues will be settled and would be very helpful for the company. Though at the start, this may be tough for every branch to adopt with, the expected result is very profitable for them. In fact there will be less work for the agent and the name of company will receive good feed backs. Remember that it is not the name of the Manager, members of the board or the agents, names that are on stake but the name of the company. It is true that most clients inquire on the same issues commonly normal issues. The price or fee that people pay in acquiring contacts from the insurance company is already expected or predicted but certain matters like not being contented with the service given by the agent and not giving immediate action to complains are very critical for the company. There may be a lot of negative speculations that may come from other employees of the firm but the focus must still be in the whole company and for its good. It may be that it can create undesirable misunderstanding between the duties of the agents and the call center employees if there would be specification of work.

Choose one example of a real protectionist policy that has been Essay

Choose one example of a real protectionist policy that has been implemented by the government of some country and discuss the is - Essay Example Under non-automatic licensing requirements importers need to approach authority for the pre-registration and pre-approval of all imports into the country (USTR, 2012). Over time, rather than eliminating these measures, Argentina brought almost 600 items that include textiles, consumer electronics, bicycle parts, glass, metallurgical products and many more under the ambit of non-automatic import licensing procedures from February 1, 2012. The new requirement served two purposes: firstly, discouraging importers with lengthy and expensive customs procedures and secondly, strengthening domestic economy by supporting local producers. This has impacted many countries worldwide including European Union, the US, Japan, Mexico for they will not be able to export goods to Argentina. Arguments for Setting Such Policy It is important to note that Argentina, apart from being a WTO member, is also a member country of the Mercosur Customs Union and cannot arbitrarily change its tariffs. That is why it has resorted to a novel practice of imposing non-automatic import licensing system for all goods precisely to circumvent WTO and Mercosur free trade rules (Bendini, 2012). Mercopress (2012), a south Atlantic News Agency, reports that Argentina has imposed new restriction on imports in the garb of non-automatic import policy to safeguard domestic producers of the country. European Union Substantially Impacted The European Commission is of the view that licensing procedures adopted by Argentina are cumbersome, lengthy taking more than six months or longer (WTO prescribes 60 days) to complete. It also lacks transparency. Even goods that are not subjected to non-automatic import licensing procedure need to pass through a long and tiresome preapproval import procedure. In 2011, European Union export to Argentina was valued at EUR8.3 billion. Obviously, EU has been impacted significantly due to this protectionist policy of Argentina to curb imports (Bendini, 2012). According to Europe an trade commissioner, Karel De Gucht, the Argentine restrictions on imports have impacted a wide range of European exports of products such as mobile phone, laptops, cars and household appliances. De Gucht argued that as many as 19 WTO members have raised concerns against protectionist policies of Argentina and they would initiate a consultative process to solve the issue and if not resolved, then the EU would approach WTO to establish a panel of arbitrators to decide on the legality of Argentine action (Moss, 2012). Several Other Countries also Affected It is pertaining to note that Mexico, Japan, and the US have filed their separate complaints with the global trade arbiter regarding Argentina's new import policies (ICTSD (2012). In April 2012, at the Import Licensing Committee Meeting of WTO, several member countries that included Japan, Australia, the EU, Turkey, Thailand, Norway, the US, Costa Rica, New Zealand, Colombia, Peru, Chinese Taipei, Korea, Canada and Switzerland comp lained that their exports to Argentina had gone down due to Argentina's licensing requirements. They further complained that Argentinean government had put almost 600 products under a list that required individual approval for import (WTO, 2013). In 2012, similar

SWOT Analysis Research Paper Example | Topics and Well Written Essays - 1000 words

SWOT Analysis - Research Paper Example The airline is known for embracing inventive technology to advance the client experience. The company traces its origins back to 1932; an amalgamation with Star Air service in the year 1934 established the biggest airline in Alaska, which ultimately became Alaska Airlines. Contrasting the rest of the economy, Alaska has been experiencing increasing important revenues from oil dealings and tourism. Air travel is Alaska’s largest type of transportation due to the natural features of the region and weather. Alaska has above one thousand airports along with 3000 avenues of landing. The airline immensely contributes to the state’s economy through air travel because Alaskan travels constitute a large percentage of overall air travelers in the United States. Alaska Airlines is committed towards offering convenient, quality and affordable air transport services to its clients as well as service to the state, nation and vast society. Values of commitment, ethics, integrity and q uality govern the operations of the airline company and are the reasons behind its huge successes. II. Organizational Strengths and Weaknesses Alaska Airlines has a strong and reliable customer base in Alaska State, where it is a dominant player. This is among the strengths that the airline company has in the sense that the company can rely on its vast customer base to expand and introduce new products, which will be readily acceptable in the market (Gates, 2006). A strong customer base is a distinctive strength because it positions a corporation so that it can operate in the market better. Customers are the essence of any company, and a reliable pool of customers who are loyal to a company is good for the firm. Therefore, Alaska airlines can benefit from its large customer base by expanding its operation to serve other regions and countries as well as introducing new services and products. In fact, the most credible significance of this strength is that Alaska airlines can utilize customer feedback to launch its strategies and products. Alaska Airlines is a huge contributor to the economy of Alaska State – this could be another major strength of the company in the sense that it endears the airline company to the government. As a result, the airline can obtain better services. It can be considered a distinctively competent strength because it can propel the company to greater heights in the market. For instance, the airline can benefit from government support in line with its great contribution to the economy. Alaska airline has several weaknesses, which ought to be addressed to avoid any inconveniences in the process of its business operations. The airline relies so much on the geographical and climate conditions, and a majority of its customers hail from the state of Alaska. This is considered as a weakness because should other airline companies venture into Alaska, the company may lose its market share, which is primarily based in Alaska. The organiz ation can minimize this weakness by expanding into other states and countries (Ritcher & Pahl, 2009). The strategy of Alaska Airlines is targeting the passenger traffic as an indicator of its corporate success. This is considered a weakness because it could trigger an organizational failure due to lack of broader strategic planning. In essence, passenger traffic is not
