Electronics Laboratory Report.

Laboratory Long report. Electronic laboratory practice Abstract: The aim of this laboratory was to make us familiar with how to use the different types of electronic equipment and how to accurately use them to make measurements. The equipment used in this laboratory included: (i) the signal generator which was used to supply the power used in the various procedures, (ii) The oscilloscope which was used to view and record the waves produced from the AC currents and then make relevant calculations based on that. iii) The DC power supply was used in the first two procedures which involved using the resistors. (iv) Familiarised with the multimeter and used it to take measurements (v) the experiment board which was used to do create most of the circuits and take the necessary measurements. Procedure 1: The measurement of resistance. The resistances of the 5k? and 22k? resistors were found using the theory and by taking the actual readings. The resistances of the resistors were first measu red by comparing the colour bands on the resistors to the colour code chart provided.The procedure for this is: there are four bands on each of the resistors, and each colour on the band denotes a specific number on the resistor colour code chart, which gives us the significant figure and the multiplier which is in powers of 10. The values using the colour code were calculated and found to be as follows. * 5. 1k? with a  ±5% tolerance * 21k? with  ±10% tolerance. These nominal values are the ones that are calculated but in reality the actual values of resistance can be a bit different from the ones calculated due to impurities.The actual resistances are measured by using a multimeter, the way this is done is that the resistors are mounted on an experiment board and then the multimeter is connected right across it. The values were recorded and found to be as follows: * 5. 037k? * 21. 047k? | Nominal value| Actual value| 5k? resistor| 5. 1k?  ±5% tolerance| 5. 307k? | 22k? resis tor| 21k?  ±10% tolerance| 21. 047k| In conclusion, it can be seen that there was a difference in the calculated nominal values of the resistors and the actual ones which were calculated.But they were still within their tolerance levels; there could be plenty of reasons for that which might include different types of batteries, differences in temperature of the room, impurities in different sections of the experiment board which might have affected the readings. ’ The tolerance level is defined as an allowable variation from a predefined standard. A value from an experiment or a variance is not considered significant unless it exceeds the limit set by the tolerance limit. ’ – www. bridgefieldgroup. om/bridgefieldgroup/glos9. htm For this reason, we can assume these differences in the actual values of the resistors to be insignificant since they were within the stated tolerances. Procedure 2: The measurement of voltage. In this experiment, the principle was to create a voltage divider circuit and to carry out the required measurements were undertaken to prove the principle of the voltage divider. For that, a circuit was created where a supply voltage was applied across two resistors R1 and R2 in series as shown in the figure below.And the two equations shown below were used to make the necessary calculations. Image source: http://www. ermicro. com/blog/wp-content/uploads/2008/11/basic_r01. jpg http://diy. griffshp. com/wp-content/VoltageDivider. jpg The experiment was carried by using two resistors of values R1 equal to 5k? and R2 equal to 22k?. The resistors were mounted on the experiment board and the voltage divider circuit was created. The power was supplied using a +6v power supply and the voltages across each of the resistors was calculated using the Agilent 34401 multimeter.The values were recorded and were found to be as follows: V1=1. 1846v V2=4. 89v The total of the voltages adds up to be 6. 0167v which is roughly about 6v ( the initial voltage supplied) which proves that the voltages are within the required tolerance. To compare these measured values to the nominal values which can be found using the voltage divider equation, substitute the values of R1 and R2 and use V as 6v to find the voltages across each of V1 and V2. v1=6*55+22=1. 11v * V2=6*225+22=4. 88v | Nominal values| Actual values| V1| 1. 11v| 1. 1846v| V2| 4. 88v| 4. 89v| In this experiment it was found that the actual values and the nominal vales were not much different from each other. This could have probably been because of the resistances in the wires or loose connections. But they were both within a tolerance level of 5% which makes the difference insignificant and accountable for experimental error.The outcome of the experiment was that the voltages were shared between the two resistors and the larger resistor got the larger share of the voltage whereas the smaller resistance got the showed smaller voltage passing through it. This prove d the values that we found using the nominal calculations of the voltages. Procedure 3: current measurement. In this experiment, we use the current divider rule which is similar to the voltage divider equation except that the way the circuit is constructed is it is in parallel instead of series.The experiment was set up in the method shown below and the necessary calculations were made. The circuit was constructed as shown in the schematic above and a DC voltage of +6v was passed through it, the currents were measured in each of the resistors and found to be: * I1(current across 5k? ) =1. 182A * I2(current across 22k? )=1. 192A (Ps: The rest of the rest of the report could not be completed since the original lab was not completed on time and hence the required information was missing. ) Table of Contents: 1.

Favourite Book Essay

The best book ever is German First of all I have to admit that I’m not a great book-lover, I don’t read a lot and this is a pity as I know I could improve my knowledge, my vocabulary, my ability in speaking and my fantasy too, but unfortunately I can’t find lot of free time to dedicate to books. Or, when I find it, I get tired soon and I can’t stay concentrate for a long time. Sometimes I re-discover the pleasure of reading especially when I find a book –or an article- that captures me. This has been the case of Christiane F.- Wir kinder vom Bahnhof Zoo, an extraordinary book I read twice (never happened before) that I can consider my favourite book at all. Christiane is a girl who lived the crazy Seventies in Berlin; in this autobiographic book she tells her unregulated life from the difficulties of the childhood to the age of twenty, when she had just came out of the tunnel of drug. Her rough father divorced from her careless mother and Christiane, with her little sister, had to move to Gropiusstadt, where she met the degrading side of life. When she was 12 she smoke marijuana for the fist time, following with LSD, ephedrine, mandrax, until she turned 14 and took Heroine. Since then, she had been taking drugs almost everyday, earning money with prostitution and little robberies. Her mum, after having found the girl fainted in the bathroom with a syringe in a vein, tried every possible rehab but she succeeded only at the age of 17. Christiane still lives in Berlin, has a child and she has had some relapses, but she never forgets her story, also made of friends who died for overdose. I think her life is told in a super-realistic way, full of passions, feelings and emotions that the reader can sense in first person. I loved so much this book that I went to Berlin and I visited Christiane’s places trying to imagine what was the context like at her age. I have hundreds of thing to add, but I must finish here, so I recommend this book with all my heart !

People Led District Disaster Management Essay

Soon after the Orissa Cyclone and thereafter the Gujarat earthquake the Government of India prioritized a national policy on disaster management and advocated a change of direction from a post disaster reactive approach to a proactive stance before the occurrence of disasters, provided a new legal framework and greater harmonization of disaster management efforts. The policy set forth principles (including significant community role and active civil society participation), objectives (including emphasis on prevention, DRR and promoting regional and national cooperation), strategies and provisions for promoting inter-sectoral complementarities. The Disaster Management Act 2005, mandates National, States and district authorities to develop policy, guidelines, plans for proper implementation of Disaster management plans to reduce adverse impact on communities and to facilitate timely and effective response. It stresses upon inclusion of mitigation, preparedness and DRR measures into development. As a result SDMAs in various states initiated development of district disaster management plans. However, some plans were merely a collection of contact phone numbers of important authorities and departments from the district. There were significant gaps in these operational plans mainly due to non availability of a standard framework, lack of expertise and dedicated resources. Lack of community participation and that of relevant stakeholders in the preparation process has resulted in lack of ownership among intended users and beneficiaries. Disasters tend to happen to people at risk. People are at risk because they are vulnerable to hazards. This vulnerability can be best reduced by increasing people’s capacities to deal with underlying social, cultural and physical factors. The key to successful disaster management plan is to ensure involvement of people who are victims and who are at risk or could be potential victims. If this is not practiced it is often unsustainable, costly and ineffective. Most DDMPs in the country lacked participation of affected communities and civil society. A participatory community level disaster management involves a cross section of people in the design and development process of the plan. When local people develop these plans there is more interest, greater ownership and understanding resulting in successfully reducing suffering and losses. The key principles of this approach thus are: * Community themselves are best placed to prioritize threats and take effective risk reducing actions. The best time to reduce the impact of disasters is before the next disasters occur. Hence, preventive actions should be integral part of the effective disaster management plan. * The identification and mapping of hazards along with who and what may be affected is necessary before risk reduction plans can be made. * Progress has to be well publicized to maintain interest and strengthen the culture of disaster reduction. An example of this is found in the recent NDMA/SDMA collaboration with civil society coming together to develop community led DDMP in Madhubani. One of the basic highlights of the Madhubani DDMP process is that though it oriented towards response but it also incorporates reduction and prevention thrust. Incidentally, prevention has been recognized as an important aspect of DDMP by the district and state/SDMA but also in the poverty reduction strategy. As a result of DDMP several agencies/departments in Madhubani have shown willingness to incorporate prevention measures in their regulations, such as the building codes by the town planners that regulate development of settlements. It was encouraging to note high level of commitment from various stakeholders to improving DRR mechanism. Tearfund has been working along with its partners to lobby with governments at all levels for influencing the policies and development of effective people friendly plans. The Madhubani DRR project implemented by its partner organisation EFICOR in 30 villages in Madhubani was instrumental in development of pilot District Disaster Management Plan (DDMP) along with support from SPHERE India. The strength of this pilot has been the process it has embarked upon wherein involvement and participation of all level of stakeholders from community to district/state/national government authorities in development process of this DDMP. In view of intensive involvement of all relevant stakeholders the pilot has received good response and acceptance from the NDMA and SDMA. This is considered as the first ever attempt in developing a DDMP which has come up from the active involvement of first respondent in any natural disasters. As mentioned above the thrust of development of DDMP is that it is being developed involving affected community, hence, the approach has been bottom-up, however at the same time, all relevant stakeholders, be it government departments or the NGOs and other actors have been involved and participated at all stages of development of the plan. This is truly a plan developed by the people and for the people. This plan has also influenced many other civil socieities to take up similar preparations for other districts and states with the support of NDMA.

About movieHome Alone - Essay Example The 103 minutes long movie is highly entertaining and justifies its tremendous success with its top position in the box office rating for 12 straight weeks. The plot is a dream come true fantasy for children. Kevin McCallister is accidentally left behind during the Christmas when his family rushes to catch their flight for Paris where they are to celebrate Christmas with friends and relatives. While the family realizes the faux pas only when they are airborne, Kevin is delighted to find himself all alone at home. His mother, Kate remains at Paris airport to catch the first flight for home and after much ado she finally reaches Chicago to be reunited with her son. Meanwhile, Kevin is having a gala time, enjoying all the things which were earlier forbidden like watching TV, eating junk food etc. The movie takes a turn for more riotous comedy when Kevin thwarts the intentions of two burglars who come to rob the McCallister home by playing mischievous pranks which are the highlights of the film. The film is a light comedy which a family can enjoy with unadulterated fun. It is realistic in the dreams that children would like to come true because all children just wish that their parents would disappear so that they can do what they want and have fun all day without any parental control. At the same time, it must have been nostalgic for some adults who had such fun playing pranks as Kevin had done in the film. At the same time, the elaborate planning and booby traps made by eight year old Kevin look too good to be true (Goldberg, 2000). But overall, the film was a huge success because it was fantasy filled comic play of shenanigans that children love. Even though the mischiefs are a little overboard, the director had succeeded in capturing the attention of the target audience. Smith (2013) has correctly summed up the film as it ‘showed kids an irresistible world stripped of parental control’. It was

Despite the criticisms often levelled at the Community institutions Essay

Despite the criticisms often levelled at the Community institutions and their powers to legislate, it should be remembered that ultimate power still lies with t - Essay Example The legal scheme said to be designed by the Treaty at the outset has been assessed as having shortfalls in its objective of ensuring that the EC law be properly applied by the Member States. Article 169 procedures as a legal instrument in fighting against all the failures to fulfill obligations accordingly is not appropriate. This implies the need to create additional means to enforce and supervise the EC law (Gil Ibà ¡Ãƒ ±ez, 1997). To date, the Community and its underlying legal order can only hold on if that legal order is safeguarded and complied with and the Community law directly applied, with its primacy over national law (ABC of community law, 2004). For all its imperfections, however, the European Community legal order is said to have greatly helped in solving the political, economic and social problems of the Member States (ABC of community law, 2004). But there is yet the tag and pull when it comes to location of power in most aspects. Different institutions cooperate and govern the European Union and the most important of these are the Council, the Commission, the European Parliament and the Court of Justice. (EU Law, n.d.). With its own set of legislation, the European Community also has the laws of its member states. EC Law is concerned with treaties, regulations, and decisions of the European Court of Justice (Ibid). Made within the part of the European Union called the European Communities (EC), the EC Law is only the legislation that is applicable, hence called EC law. Based on the Treaties, it is the fundamental rules of the EU serving as agreements between the Member States. EC law comprises four different fields, namely primary law (the Treaties and the accession treaties of the new Member States), secondary law (all existing legal acts accepted by institutions of the European Union), international agreements between the European Union and

Finance Accounting Essay Example | Topics and Well Written Essays - 1000 words

Finance Accounting - Essay Example The accounts above are made in light of portraying a true picture to the shareholders as well as any investors interested in the company. The true and fair view concept has been at the heart of financial reporting in the UK for over forty years. In recent years there has been a major increase in the international importance of this concept. This has come about with its adoption by the European Community in the Fourth Directive on company law and its implementation in all Community countries. However, this concept has never been defined in UK legislation, and a variety of meanings can be attributed to it. In view of the recent international developments and given that the UK is the source of the concept, this study sought to elicit the views of senior UK practitioners on the true and fair concept. The FRC has laid three points: that the concept of the 'true and fair view' remained a cornerstone of financial reporting and auditing in the UK; that there had been 'no substantive change in the objectives of an audit and the nature of auditors' responsibilities'; and that the need for professional judgement 'remained central to the work of preparers of accounts and auditors in the UK'. To support the application of the "true and fair view", accounting has adopted certain concepts and conventions which help to ensure that accounting information is presented accurately and consistently. The most commonly encountered convention is the 'historical cost convention'. This requires transactions to be recorded at the price ruling at the time, and for assets to be valued at their original cost. This is applicable when the calculations were made for the fixed assets of plant and machinery, fixtures and fittings and buildings.

Under the "historical cost convention", therefore, no account is taken of changing prices in the economy. The other convention used is the monetary measurement concept.

Corporate social responsibility (with an example) Research Paper

Corporate social responsibility (with an example) - Research Paper Example It is not right to say that Corporations are excluded from societies; they are part of it and hence have a role to play within in the society circle. It is the society which gives them the name and recognition, and in return there is much to be given back to the society as well (Asongu, 2007). A society could be broad in the spectrum like an oil company whose impacts are there for entire environmental system, similarly a society could be small like for a grocery store whose items are only benefited to the specified group of people. Hence Corporations are part of societies and to survive in business they have to understand the societal norms and responsibilities (Horrigan, 2010). Analysis based Point of Opinion According to scholarly literature, it can be indicated that corporate social responsibility is a modern concept and has been compiled from various definitions. According to modern literature, corporate social responsibility is a business norm that includes all the business comp onents in one domain, like it includes buyers, consumers, share holders, employees, and communities which have to be served in one system (Asongu, 2007). Hence CSR is a broad concept, a concept that reaches out to each component attached to its system (Asongu, 2007). ... In Worlds tropical regions like South Africa and North India, there have been infectious disease spreading, like malaria and leishmaniasis for which there is no cure provided just because of high poverty and fewer paybacks to the pharmaceuticals (Hirsch, 2008). On the other side, there are no cures for chronic diseases (tuberculosis) as pharmaceuticals have forgotten the moral responsibility and have prioritized wealthy attainments than society. The cures are there but the will is not and due to economic reasons and not scientific, pharmaceuticals have stopped to research and develop. It is all because the priority is wealth and money, so the norms of society, virtuousness and morality have got disappeared in the tropical regions (Hirsch, 2008). From the modern perspective, it is not wrong to say that virtue and social responsibility are just matters of the book and scripture and not more than that. According to Lynn Payer (author of Disease-Mongers, 1992) medicine industry has been dominant due to several reasons, one of the main reason is disease mongering, a concept that brutally destroys the notion of corporate social responsibility (Dossey, 2010). In the modern system, medicine industry (pharmaceuticals) generates more than one trillion dollars each year. One of the secrets for such dominating figures on revenues is disease mongering â€Å"expanding diseases and developing the demand† (Dossey, 2010). Out of the trillion, billions are spent on advertisement and marketing campaigns, which is all to bring response and acceptation from the customer. One harsh fact is that patients are customers, customers that bring demand for the industry. Hence it is not harsh to say that the system of 21st century itself is violating the
