How Homework can Help with Your Academic Success Essay Example for Free

How Homework can Help with Your Academic Success Essay Homework is an important part of the academic curriculum and it also plays a major role in ensuring academic success for the students. Let us talk at length about how homework can help in bringing about academic success. Homework primarily helps in building five skills which assist in attaining academic success. Those skills are as follows: Organization: Being organised is an essential ingredient in the recipe of academic success. One has to be meticulous in planning a study routine to ensure that all topics of all subjects are paid equal attention. Also, enough time for practice should be baked in the routine. It is this aspect that homework helps with and gives enough opportunity to a student to practice his/her lessons, which then paves the way of gaining mastery over a topic or subject. In addition keeping track of one’s homework makes a student more organized. Time management: Optimum utilization of time is the key to success in the field of academics. Often at times, one feels flustered and overwhelmed with the vast study syllabus or curriculum. Therefore, dividing one’s time efficiently and as per one’s strength and weakness is a matter of great importance. Homework provides the student with an opportunity to manage time. While doing the homework of a subject which is one’s weak area, he is devoting more time to that subject, which will help him in understanding the concepts better, thereby saving the student’s time as he need not revisit this subject again and can spend the rest of his time in doing other activities or can devote to other subjects. In addition, learning to plan his work well in order to submit the assignment or homework on time will help him/her build time management skills. Prioritization: The skill of being able to prioritize one’s task does not only help with academic success, but is a skill which will come handy throughout your life. If a student is confronted with multiple assignments or homework in multiple subjects, he/she needs to prioritize it based on some factors like submission date, the complexity level of the work, his/her proficiency level with the subject etc. While doing so, they will learn to identify elements based on the urgency and importance levels. Concentration: Undivided attention and wholehearted commitment to one’s study time are per-requisites for academic success. While doing one’s homework with complete focus, a student has to ensure that he is cut off from any kinds of distractions or interruptions and should devote all his stamina and attention in completing the homework effectively. Such single minded focus on completing one’s homework helps a student build his concentration, which proves to be very useful while studying during the time of the assessments or exams. Motivation: A student has to believe in self and has to remain motivated all the time to be successful in academics. Self-confidence is of prime importance for academic success and it can be built and retained only if an individual is motivated to achieve success. If one does his/her homework successfully and wins accolades for the same back in school, then he/she will be motivated to do well consistently, as nothing attracts success more than success itself. To summarize, if homework is done with seriousness and sincerity, then it can prove to be a very useful tool in achieving academic success.

Analysing The Performance Of Aegon Group Business Essay

Analysing The Performance Of Aegon Group Business Essay AEGON Group is world leader in financial services business which provides life insurance, pensions, long term savings funds and investment services and products. AEGON Group has 30000 employees and serving over 40 million customers globally. AEGON Group provides services and products over twenty five countries globally United States, United Kingdom, Europe and Asia. By 1994 AEGON started relationship with Scottish Equitable, which was very popular and well known name in the United Kingdom as a financial service industry. Scottish Equitable founded in 1831. By 1998 AEGON had taken complete control of Scottish Equitable and Scottish Equitable was rebranded as AEGON Scottish Equitable in 2006. After two years the Group extended its businesses in the United Kingdom and bought life insurance operations of Guardian Royal Exchange. AEGON main customers are United States, United Kingdom and Netherland. AEGON withdrew some business from Belgium and Greece, also general insurance from the Unit ed Kingdom market and healthcare sector from Netherland. The Group also sold its stake in FGH Bank and merchant bank Labouchere. The result was a more efficient and better concentrated organization. AEGON playing very important role in its markets just not in United Sates, Netherlands and United Kingdom but also in new markets of Asia, and central part of the Eastern Europe as well. AEGON is listed on the stock exchanges of Amsterdam, London, New York and Tokyo. Task -1: Explore the background to change affecting the current organization. P -1.1 Discuss the background to change that exists in today economy. Change is a powerful force or an engine that drives many segments of our economy. Mostly forces of change provide us as contractors with new projects to build and older buildings to modify or amend. Changing is truly the lifeblood of our businesses and our economy. The forces of change are also more subtle and pervasive as its affect our economy, our businesses, our jobs and even our daily lives as well. We might easily recognize changes as progress in physical world of production, but maybe we fail to recognize other forces in our economy, our businesses, our jobs and even our personal lives. Failure to recognize force of change can only lead in downward spiral to lower efficiency, lower profitability, lower productivity and lower personal in-effectiveness. Change is continuous adoption of organization strategies and structures to changing external environment. Today change is ongoing process in our economies, our businesses, and our lives. Change that exists in todays economy The competitive pressure forced the changes bring into our economy. There are several major forces for changes that exist in today economy and financial sectors. These forces are: Bureaucracy Environment changes Climate change Economics changes Political changes Technological changes Personal behaviours changes Changes in turn started the industry globalization We can see incidents in past changes the businesses and economic environment which is responsible for changes exist in current economy. Bureaucracy effect in our organization and economy because management were use resources to person needs rather than organization goals. Max Weber saw bureaucracy as the most rational and effective mode of organizing the activities of large numbers of people because it ensured decision-making according to general rules rather than the whims of officials, cultivated trained experts, and reduced the possibilities of corruption and nepotism. Weber, M., (1979): Economy and Society, in: Journal of an Outline of Interpretive Sociology, Volume 2 The global economic crisis that started in the US in 2007 and spread around the world in 2008 was preceded by large imbalances in global capital flows. The economic crisis has changed world economy during the past year alone, slowdowns economic growth. The IMF says this represents By far the deepest post-World War II recession with an actual decline in output in countries making up 75% of the world economy BBC News. (April22, 2009): (Online). Available at: www.bcc.co.uk The evidence shows that ignoring climate change will eventually damage economic growth. Our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century. And it will be difficult or impossible to reverse these changes. Tackling climate change is the pro-growth strategy for the longer term, and it can be done in a way that does not cap the aspirations for growth of rich or poor countries. The earlier effective action is taken, the less costly it will be. NICHOLAS STERN, STERN REVIEW: THE ECONOMICS OF CLIMATE CHANGE LONG EXECUTIVE SUMMARY ii (2006) Economy growth slowdown, unemployment is up, house price fall down and these changes, changed people mindsets and their spending habits in order to survive this difficult time. Managers across the UK, meanwhile, have accepted their own redundancy as inevitable, according to the Chartered Management Institute. Those factors are cause to a lot of stress for us all our society and individually. There also In near past the world economy was not good even before September 11.Synchronized growth slowdowns and in the case of recession in Japan were already under Way in the US, Europe and Japan, while developing countries were facing weaker export demand and increasingly difficult financing conditions. After the shock of September 11 have changed the picture, increasing the already significant downside risks to world growth Fischer, S., October 18, 2001: International Monetary Fund. 32nd IAFEI World Congress, Cancun, Mexico The Changes in the political environment is also one factor to change in today economy. It is difficult to say that these changes are simply short-term reactions to a major shock or amount to new and worrisome trends. At the very least, the balance between political and economic forces has been significantly altered. Because political support for globalization was at best shallow while the global economy was in a buoyant state, this suggests the pendulum is now swinging in the opposite direction. Against this background, two lessons from history are worth keeping in mind. One, dismantling protections takes time. It took several decades for many of the trade barriers erected during the interwar period to be brought down. Second, even if a important part of the progress in liberalizing trade in recent times has been institutionalized and strong reversals à   la 1930s are not likely, the downward spiral of protectionism acts fast. Ferry.P.J Santos.I, (March2009). FD: Volume46, Number1 The technology is posing major challenge to todays economy that is information technology. The information technology of the computer and internet services has and will continue to changes the economy. In the world of economics, globalization is reflected in the increasing the acceptance of free markets and private enterprise as the principal mechanisms for promoting economic activities. Its growing importance is captured in such indices as trade in goods and services, private capital flows in different forms, foreign investment, information technology transfers, operations of transnational enterprises, business travel and communication, and migration and remittances Dunning, J. H. (1993): The Globalisation of Business. Routledge, London. As Labovitz Rosansky point out personal behaviour Psychologists have long recognized that human beings like people who are like themselves and tend to reject people who are different from them. So far organizations continue to create changes between people interest of efficiency. Line versus staff, management versus labour, field versus corporate, internal versus domestic, East versus West, accounting versus sales- the list goes on. No wonder it so hard to focus people around familiar goals when they are so different from each other simply by virtue of what they do and where they do it. Specialization and knowledge can be a wedge that drives people future apart and makes it difficult for them to work together Price, A., (2007): Human Resource Management. 3rd Ed, p281 Several commentators have drawn attention to the analogy with the effects of natural disasters like the Kobe earthquake in Japan that barely show up in the national accounts. It is the indirect effects that will matter most, in particular, in the short-term much depends on the effects on consumer and investor confidence and spending, which were already under strain and have been strained further by the attacks Fischer, S., October 18, 2001: IMF, 32nd IAFEI World Congress, Mexico. AEGON UK chief executive Otto Thoresen says The economic environment is challenging but we have a strong team to take us forward through the next phase of our development Many changes affected the AEGON, UK environment in recent years. These are few changes; External factors In the UK, life expectancy has increased in recent years hence people can expect to be retired for longer. In many cases, individuals have not planned properly for retirement and there may be a shortfall in the amount of money available. AEGON UK have introduced new less expensive pension schemes or insisted on employee pension contributions where they did not in the past. In an economy closed to external equity investors, such as the UK before 1979, the decline of defined benefit pensions would have been a disaster. The cost and availability of equity capital would have reflected the reduced flow of funds into the equity market. This potential concern became irrelevant as a consequence of the lifting of exchange controls and the globalisation of capital flows, which made the market more efficient while putting downward pressure on the cost of capital. Plender, J., (2010): The pensions shake-up heralds equity demand change. The Financial Times Private pensions The government pensions were very small and also government want to decrease the dependency on the state in old age. The government also have introduced private pension schemes to deceased the dependency on the state. Pension funds are increasingly being asked by politicians, non-governmental organizations, campaigners, and pressure groups to mobilize their financial clout more actively and to take their responsibilities as corporate owners more seriously. The chances are it could change from being asked to being required. Fraser, I., (2010): Pension funds search for climate change risks and opportunities Falling vales of shares The current economic downturn situation affected the company shares values, which reduce the returns on the customers investment. Customers getting less than they were expected for their investment, also people had a negative impact on pensions as well. Competition AEGON is in competition with other organisations which are selling directly to customers and those competitors also well known in United Kingdom. Also AEGON has had very poor reputation in the insurance and pensions industry in recent years. P -1.2 Evaluate the strengths and weakness of the organization. Strengths The strengths of an organization are those things that it does particularly well, especially when viewed against the operations of its competitors and also its weakness areas in which it is less strong than the competition.  ¨ AEGON had historically been successful AEGON had historically been successful but government imposed price controls had reduced profitability. Compared to its competitors, AEGON was not well known by consumers. It had developed good products and services and had a good reputation with distributors, particularly in the area of pensions which were a key strength of Scottish Equitable.  ¨ Developed good products/services AEGON developed a range of products and services to individuals, corporations and institutions. Most of these products and services fall into one of the following three categories: Life insurance Pensions Long-term savings and investments products  ¨ Good reputation with distributors Compared to its competitors, AEGON is well known and had a good reputation with distributors, particularly in the area of pensions which were a key strength of Scottish Equitable.  ¨ Customer focused organisation AEGON UK is a customer focused organization as AEGON CEO (Otto Thoresen, 2009) pointed out that We work to help keep customers needs /wants at the heart of all developments and to make sure that financial service industry works with customers to give them what they want/need and we offer the best products and services from their point of view.  ¨ Reflecting local knowledge and global power Scottish Equitable is now AEGON Scottish Equitable reflecting both local knowledge and global power. All the brands now bring a new common look which is refreshing and different.  ¨ AEGON provide the levels of return promised AEGON UK Ltd is also providing the levels of return promised and being responsible for any risks associated with doing so.  ¨ Provide products/services different levels of income for the consumers AEGON Ltd have contractual measures in place to help those customers who find themselves on low incomes and, often through no fault of their own, are unable to maintain premium payments. These measures include introducing lower premium payments, grace periods and loans or, in some cases, reducing the coverage offered by a particular policy. Weaknesses The weaknesses of the organisation are matched to the opportunities and threats that may affect the organisation and which come from the external environment.  ¨ Not well known by consumers in the UK AEGON was not well known by consumers. It had developed good products and services and had a good reputation with distributors, particularly in the area of pensions but not well known directly by consumers.  ¨ Had poor reputation in life insurance and pensions industry The insurance and pensions industry, in which AEGON operates, has had very poor reputation in recent years.  ¨ Not providing consumers with best products for their needs The AEGON Ltd is not providing the products and services in a way that genuinely meets consumer needs/wants, and also not regulator by government.  ¨ Difficult to understand financial services products Financial services/products are hardly to understand. People do not always feel which range of financial products/services they need and also are not sure where to seek support and advice.  ¨ Wide problems to remain competitive The insurance and pensions industry have been characterised by intense competition. AEGON is in competition with other organisations which are selling directly to consumers and which are also better known in the UK.  ¨ Not selling directly to customers AEGON Ltd not sells product direct to consumers, they sells products/services via salesmen, agents or brokers which sometime involves mis-selling of its products/services. P -1.3 Compare alternative forms of organizational development. When we promote the idea of making consumer aware of the organizational change, it becomes organizational development. Generally, the organizational development is considered as a method of arrangement, suitable with the contemporary requirements of the organization and also being able to fulfil the future requirements that cannot be distinguish. After reading the case study of the AEGON Ltd, The plan appears to be the organizational efficiency and effectiveness from top to bottom level. The company led by its new CEO has new objectives such as: Defining the view of where company stand. Defining how the company will stand in the future. Defining the policies and standards to reach the future goals and objectives. The purpose of the company was self analysis by defining goals, targets and objectives, how to reach them and what the management is doing to achieve these goals and objectives. AEGON took a brand audit to find out the answers of these questions and the result of the audit reveals two steps How was the company positioned? How was the competitor of the company positioned? By the audit, the new CEO came to know that there is a need for formation of the new approach (play in the market). The staffs were adopted with the innovation and well organized communication system. Additionally, self analysis has helped new CEO to position a fresh plan to craft progress. The new plans resulted for the organization to involve in the following strategy steps: Simplify financial service and provide more focus. It was important that consumers understood more precisely what they were buying as well as the benefits and services they received. By making products and services clear to the consumers, to many of goal organization achieved and too many very important stakeholders introduced to the change. Both of the stakeholders (government and consumers) are aware and happy, because of services provided by AEGON, these steps were taken for the customer to make them aware and solve problems. Develop the workforce. The objective was to develop the skills, needed within the business and to involve the stakeholders in process of change, by providing them training and skills. Therefore, AEGON also created new opportunities for stakeholder to progress from one job to another job by developing and promoting the careers of work force. This helps AEGON to attract more customers and have competition. Organizational culture may include such things as, confidence to innovation, decisions and trust for production and quality. The model, implemented by new CEO of the AEGON, brought positive change in the organization and gave new direction to the company. Fundamentally, representation of simplify system with regard to the AEGON can be evaluated as follows; Analysing the factor affect the organization Organizational performance and future plans are constantly affected by the external and internal environmental factors. For success in the present world, one need to consider not only the internal environment of the organization consisting of its resources and employees, but needs to consider the external factors as well. These facts cannot be stopped but can adjust accordingly as per the changes in the political, economical or social pressures. These are the external aspects which consist of: Competitors or Opponents The change in the economic structure The Impact of the society/culture Financial agreements Political or Legal system Impact of the environment Analysing the weakness and strength of the organization A range of organization functions which determine an organization strength and weaknesses include production function, management function, Research and Development, marketing function, sales function, HR function, procurement function, logistics function, and various other departments within the organization. For example, organization strength can be derived from the excellence human resource in the organization which might not be present in some of the competitors in the insurance and pensions industry. One more example includes marketing function i.e. if an organization is not effective in marketing efforts, competitors may take advantage of the firms weakness. So AEGON Ltd need highly competent in achieving competences in all these areas of business in order to be successful in the business environment. Determine the goals and objectives of the organization It aims to boost organizational performance by aligning goals and objectives throughout the organization. Ideally, employees get key input to identify their objectives, time lines for completion etc. Management by objectives to be effective, individual managers must understand the specific objectives of their job and how those objectives fit in with the overall organizational objectives set by the board of directors. Involving the stakeholder to process of change Involving the stakeholder, how well does the organization Involve stakeholders in problem solving? Keep stakeholders informed of status towards organizational objectives? Act on feedback from stakeholders? Mobilize the right resources at the right time to adopt the implementation initiative? Create a critical mass of effort by impacted groups to propel the change? Strength Risk Dr. Baba, M., (2005): Change Management. The Defence Logistics Enterprise. Transforming Organizations in the Information Era. Enterprise Integration Group Creating new culture in organization Changing culture in organization helps to improvement organizational objects. Changing culture involves changing the basic values, beliefs, norms, etc., with the individuals of the organization in order to improve overall organization performance. Whether or not it is possible to fully manage change, we believe that being very clear about what changes are required and being very intentional about building a culture that supports the new mission, goals, strategies and practices increases the probability of success exponentially. This necessarily involves a large cross section of the organization in assessing the current system of norms and beliefs, determining what changes are needed, and designing an implementation plan ( Shorb, J.K and Jones, M.D. 2009 ). The result of the change was increase in the efficiency and effectiveness, the company improve its strengths and over comes its weaknesses, the pattern of the behaviours and business culture was developed in the organization and base of the organization to learn from its experiences was forms. Task -2 Develop systems for understanding and involving others in the process of change. P-2.1 Identify systems to involved appropriate stakeholders in the introduction of change. Stakeholder is someone who has some stake or interest in the changes and development of the organization, such as share holders, employees, government and customers. The new CEO consulted with different stakeholders of the company and then formulates a plan of action which includes following aspects: Simplify to financial services and customer focus It was important that consumers understood more specifically what they were buying, as well as the benefits and services they received. The new CEO make understandable to customers, what were company services and products, and what we going to invest and also what will possible to investment returns. Both of the stakeholders and government were unhappy because services and products were not good but after this step taken by new CEO to clarify methods and they become more aware to this regard and problem has been solved. Developing the workforce The purpose was to develop the  skills  needed within the company to help it change. AEGON also created opportunities for progression from one job to another job and usually one service to another service. Creating a distinct market place for the organization Create a more different presence within the marketplace. This involved refreshing the AEGON  brand in a means that made it more distinctive from its competitors and more attractive to his  consumers. The new CEO has taken some steps in following ways. External promotional: External promotional campaigns emphasised the relationship between Scottish Equitable and AEGON. This helped to support the local familiarity and the global power of the Organization in UK. The CEO talked to media: The new CEO talked to media about the refreshing of the brand internally and externally resulted in strong positive response. AEGON has launched new and innovative products: AEGON has launched new product e.g. the five for life pension has helped to change the way in which consumers can look at their retirement income. AEGON provide more certainty about the levels of income for customer, with providing the levels of return promised. P-2.2 Analyse and evaluate these systems. The change in the system of the organization brought positive influence internally and externally. The big challenge was to convince the stakeholders, the importance of the change in the organization. For the achievement of this objective, new CEO manoeuvre from improving skills of the workforce, he linked this growth to certain behaviours: These eight behaviours are; Think customer Embrace change Encourage excellence Act with integrity Decisive action Work together Learn and grow Relate and communicate Customers less awareness is one another reason of the change in the organization, this was also reason of the government increased tax impositions. As result of this, the company was losing customers. Knowledge of the service and product was made available through AEGON information system. Training and retraining of the employees was another aspect of the change. Finally, the company has to regain its reputation and built a brand name for its stakeholders, and the CEO responded to this challenge by bringing well known brand shares which recognise AEGON in front of its stakeholders. Furthermore, AEGON moreover revive its brand name to hold its market position though merger with Scottish Equitable (now known as AEGON Scottish Equitable), which gave company a new look. Task- 3 What were the models implemented for ensuring ongoing change. P-3.1 Adapt an appropriate model for change. The model, implemented by new CEO, brought positive and contrastive change and gave company new direction. The CEO already mentioned the performance of company through reforms in culture. As mentioned previously, both of the stakeholders (government and consumers) are aware and happy because of services provided by AEGON. These steps were taken for the customer to make them aware and solve problems. With regard to AEGON model, implementation will bring some changes which can be categorised: Analysing the factor affecting the organization. Analysing the weaknesses and strengths of the organization. Determine the goals and objectives of the organization. Involving the stakeholder to process of change. Creating new culture in organization. As Kotter, (1995) describe in Leading Change helpful model outlines an eight step process with suggestions to help organizations transform. Kotter model is useful in understanding that the change process takes time and is not something that happens immediately. It is important for program leaders and communications staff to understand that the steps needed to support any transformation plan takes place during all stages of project. Each step acknowledges a key principle identified and people can see changes, feel the changes. These eight steps: Increase Urgency AEGON pensions provider has suggested that the issue of the government helping public to put money away for retirement is of greater urgency now than it ever has been. (AEGON UK chief executive Otto Thoresen. 2010) Build the Guiding Team Get the guiding team to create the right vision and strategies to guide action in all of the remaining stages of change. This is a difficult and increasingly complex market in which AEGON Ltd is committed to offering adviser partners the ongoing help they require. We are confident that we have developed an investment proposition that meets the needs of advisers and their clients now and in a post RDR world. (Andy Marchant., 2009. Life and Pensions Marketing Director at AEGON) Get the Vision Right A shared sense of urgency for change may push people into action, but it is the vision that taking them in the right direction. A good vision offers a compelling, motivating the picture of the future and serves several important purposes. Communicate for Buy In Communicate changing vision and strategies to create understanding and buy-in Keeping communication uncomplicated and heartfelt not complex and technical Know what your individuals are feeling Speak to anxieties, confusion, anger, fear Empower Action Empower action mean is a deal effectively with obstacles that block action, especially disempowering bosses, the wrong performance measurement and reward systems, lack of information, and lack of self confidence. Create Short Term wins A short term win boosts employees confidence in the process, helping to make their efforts seem worthwhile, and gives the people responsible a chance to relax and enjoy their achievements and also link achievements back to the original vision, quieten the cynics and resisters and strengthen support from organization. Consolidating achievements and progressing Continuing with wave after wave of change, not stopping until the clear vision is a reality no matter how big the obstacles. Make Change Stick Change simply sticks when the people it affects are involved. All change is either rejected or embraced by the employees who have to live with its outcome. So its always better to involve those people in the process of change and pay close attention to their hopes and fears. P -3.2 How was the plan implemented, its process and outcomes. For successfully manage change processes, it is required to analyze the phases of the process. Managers want to know in which phase they have to anticipate and what types of problems. Most successful organizations are able to adjust themselves to new conditions quickly. This needs to learn planning processes that lead to improved organizational values. Consumers were confused before the model implemented what AEGON was. The outcome of model implement for change was extremely positive and successful. It helps to recognise the company strength and weakness and its also shows that global scale was important and local brand expertise as well. AEGON brand was not promoted alongside the Scottish Equitable and not well known in financial service industry. With a new Chief Executive of UK in place 2005 of AEGON put a new plan (model). The purpose of this model implement was to meet the CEO objectives and goals. Before implement to change AEGON was unknown in the United Kingdom, much less popular in consumers and product or services offer by the company not good enough. But after the implementation of changes AEGON became very popular brand in the United Kingdom and business started growing as well. Now the alliance with AEGON is much stronger. E.g. Scottish Equitable is now AEGON Scottish Equitable thus reflecting local knowledge and also global power. In order

Development of VLSI Technology

Development of VLSI Technology CHAPTER 1 1. INTRODUCTION The VLSI was an important pioneer in the electronic design automation industry. The â€Å"lambda-based† design style which was advocated by carver mead and Lynn Conway offered a refined packages of tools.. VLSI became the early hawker of standard cell (cell-based technology). Rapid advancement in VLSI technology has lead to a new paradigm in designing integrated circuits where a system-on-a-chip (SOC) is constructed based on predesigned and pre-verified cores such as CPUs, digital signals processors, and RAMs. Testing these cores requires a large amount of test data which is continuously increasing with the rapid increase in the complexity of SOC. Test compression and compaction techniques are widely used to reduce the storage data and test time by reducing the size of the test data. The Very large scale integration design or manufacturing of extremely small uses complex circuitry of modified semiconductor material. In 1959- jack St. Claire Kilby (Texas instruments) they developed the first integrated circuit of 10 components on 9 mm2. In 1959, Robert Norton Noyce (founder, Fairchild semiconductor) has improved this integrated circuit which has been developed by Jack St Claire Kilby, in 1968- Noyce, Gordon E. Moore found Intel, in 1971- Ted Hoff (Intel) has developed the first microprocessor (4004) consists of 2300 transistors on 9 mm2, since then the continuous improvement in technology has allowed for increased performance as predicted by Moores law. The rate of development of VLSI technology has historically progressed hand-in-hand with technology innovations. Many conventional VLSI systems as a result have engendered highly specialized technologies for their support. Most of the achievements in dense systems integration have derived from scaling in silicon VLSI process. As manufacturing has improved, it has become more cost-effective in many applications to replace a chip set with a monolithic IC: package costs are decreased, interconnect path shrink, and power loss in I/O drivers is reduced. As an example consider integrated circuit technology: the semi conductor industry Association predicts that, over the next 15 years, circuit technology will advance from the current four metallization layers up to seven layers. As a result, the phase of circuit testing in the design process is moving to the head as a major problem in VLSI design. In fact, Kenneth M, Thompson, vice president and general manager of the Technology, Manufactur ing, and Engineering Group for Intel Corporation, states that a major falsehood of testing is that â€Å"we have made a lot progress in testing† in reality it is very difficult for testing to keep speed with semi conductor manufacturing technology. Todays circuits are expected to perform a very broad range of functions as it also meets very high standards of performance, quality, and reliability. At the same time practical in terms of time and cost. 1.1 Analog Digital Electronics In science, technology, business, and, in fact, most other fields of endeavor, we are constantly dealing with quantities. In the most physical systems, quantities are measured, monitored, recorded, manipulated, arithmetically, observed. We should be able to represent the values efficiently and accurately when we deal with various quantities. There are basically two ways of representing the numerical value of quantities: analog and digital 1.2 Analog Electronics Analogue/Analog electronics are those electronic systems with a continuously variable signal. In contrast, two different levels are usually taken in digital electronics signals. In analog representation a quantity is represented by a voltage, current, or meter movement that is comparative to the value of that quantity. Analog quantities such as those cited above have n important characteristic: they can vary over a continuous range of values. 1.3 Digital Electronics In digital representation the quantities are represented not by proportional quantities but by symbols called digits. As an example, consider the digital watch, which provides the time of day in the form of decimal digits which represent hours and minutes (and sometimes seconds). As we know, the time of day changes continuously, but the digital watch reading does not change continuously; rather, it changes in steps of one per minute (or per second). In other words, this digital representation of the time of day changes in discrete steps, as compared with the representation of time provided by an analog watch, where the dial reading changes continuously. Digital electronics that deals with â€Å"1s and 0s†, but thats a vast oversimplification of the in and outs of going digital. Digital electronics operates on the premise that all signals have two distinct levels. Certain voltages might be the levels near the power supply level and ground depending on the type of devices used. The logical meaning should not be mixed with the physical signal because the meaning of this signal level depends on the design of the circuit. Here are some common terms used in digital electronics: Logical-refers to a signal or device in terms of its meaning, such as â€Å"TRUE† or â€Å"FALSE† Physical-refers to a signal in terms of voltage or current or a devices physical characteristics HIGH-the signal level with the greater voltage LOW-the signal level with the lower voltage TRUE or 1-the signal level that results from logic conditions being met FALSE or 0-the signal level that results from logic conditions not being met Active High-a HIGH signal indicates that a logical condition is occurring Active Low-a LOW signal indicates that a logical condition is occurring Truth Table-a table showing the logical operation of a devices outputs based on the devices inputs, such as the following table for an OR gate described as below 1.4 Number Systems Digital logic may work with â€Å"1s and 0s†, but it combines them into several different groupings that form different number systems. Most of are familiar with the decimal system, of course. Thats a base-10 system in which each digit represents a power of ten. There are some other number system representations, Binary-base two (each bit represents a power of two), digits are 0 and 1, numbers are denoted with a ‘B or ‘b at the end, such as 01001101B (77 in the decimal system) Hexadecimal or ‘Hex-base 16 (each digit represents a power of 16), digits are 0 through 9 plus A-B-C-D-E-F representing 10-15, numbers are denoted with ‘0x at the beginning or ‘h at the end, such as 0x5A or 5Ah (90 in the decimal system) and require four binary bits each. A dollar sign preceding the number ($01BE) is sometimes used, as well. Binary-coded decimal or BCD-a four-bit number similar to hexadecimal, except that the decimal value of the number is limited to 0-9. Decimal-the usual number system. Decimal numbers are usually denoted by‘d at the end, like 24d especially when they are combined with other numbering systems. Octal-base eight (each digit represents a power of 8), digits are 0-7, and each requires three bits. It is rarely used in modern designs. 1.5 Digital Construction Techniques Building digital circuits is somewhat easier than for analog circuits-there is fewer components and the devices tend to be in similarly sized packages. Connections are less susceptible to noise. The trade-off is that there can be many connections, so it is easy to make a mistake and harder to find them. There are a few visual clues as result of uniform packages. 1.5.1 Prototyping Boards Prototypes is nothing but putting together some temporary circuits, or, as part of the exercises using a common workbench accessory known as a prototyping board. A typical board is shown in Figure 1 with a DIP packaged IC plugged into the board across the centre gap. This board contains sets of sockets in rows which are connected mutually for the component leads to be connected and plugged in without soldering. Apart from these outer edges of the board which contains long rows of sockets are also connected together so that they can be used for ground connections and power supply which are common to most components. Assembling wiring layout on the prototype board should be carried out systematically, similar to the schematic diagram shown. 1.5.2 Reading Pin Connections IC pins are almost always arranged so that pin 1 is in a corner or by an identifying mark on the IC body and the sequence increases in a counter-clockwise sequence looking down on the IC or â€Å"chip† as shown in Figure 1. In almost all DIP packages, the identifying mark is a dot in the corner marking pin 1. Both can be seen in the diagram, but on any given IC only one is expected to be utilised. 1.5.3 Powering Digital Logic Where analog electronics is usually somewhat flexible in its power requirements and tolerant of variations in power supply voltage, digital logic is not nearly so carefree. Whatever logic family you choose, you will need to regulate the power supply voltages to at least  ±5 percent, with adequate filter capacitors to filter out sharp sags or spikes. To provide references to the internal electronics that sense the low or high voltages and also act on them as logic signals, the logic devices rely on stable power supply voltages. The device could be confused and also misinterpret the inputs if the devices ground voltage is kept away from 0 volts, which in turn causes temporary changes in the signals, popularly known as glitches. It is better to ensure that the power supply is very clean as the corresponding outcome can be very difficult to troubleshoot. A good technique is to connect a 10 ~ 100  µF electrolytic or tantalum capacitor and a 0.1  µF ceramic capacitor in parallel across the power supply connections on your prototyping board. CHAPTER 2 2. REVIEW AND HISTORICAL ANALYSIS OF ITERATIVE CIRCUITS As a background research, recent work on iterative circuits was investigated. In this section, seven main proposals from the literature will be reviewed. The first paper by Douglas Lewin published in (1974, pg.76,277), titled Logic Design of Switching Circuits, in this book he states that quite often in combinational logic design, the technique of expressing oral statements for a logic circuit in the form of a truth table is inadequate. He stated that for a simple network, a terminal description will often suffice, but for more complex circuits, and in particular when relay logic is to be employed, the truth table method can lead to a laborious and inelegant solution. 2.1 Example: A logic system could be decomposed into a number identical sub-systems, then if we could produce a design for the sub-system, or cell, the complete system could be synthesized by cascading these cells in series. The outputs of one cell form the inputs to the next one in the chain and so on, each cell is identical except for the first one (and frequently he last one) whose cell inputs must be deduced from the initial conditions. Each cell has external inputs as well as inputs from the preceding cell, which are distinguished by defining the outputs of a cell as its state. Figure 2.1 Iterative Switching Systems The second proposal which will b reviewed was presented by Fredrick J. Hil and Gerald R. Peterson published in (1981, pg. 570), titled Introduction to Switching Theory and Logic Design, in this book, they discussed that iterative network is highly repetitive form of a combinational logic network. The repetitive structure make possible to describe the iterative networks utilizing techniques that already developed for sequential circuits, the author in this books he has limited his discussion to one dimensional iterative networks represented by the cascade or identical cells given in below figure. A typical cell with appropriate input and output notation is given in one more figure below (b). Now note the two distinct types of inputs, i.e., primary inputs from the outside world and secondary inputs from the previous cell in the cascade. And similarly and there are two types of outputs, i.e., primary to the outside world and secondary to the next cell in the cascade. The boundary input s which are at the left of the cascade denoted by us in the same manner as secondary inputs. At some cases the inputs will be constant values. A set of boundary inputs emerges from the right most cell in the cascade. although these outputs are to the outside world, they will be labelled in the same manners secondary outputs. The boundary outputs will be the only outputs of the iterative networks. The third proposal by Barri Wilkinson with Raffic Makki, published in (1992, pg. 72-4) titled -digital design principles, in this book, they discussed about the design and problems of iterative circuits and stated that, there are some design problems which would require a large number of gates if designed as two level circuits. On approach i.e., is to divide each function into a number of identical sub functions which need be performed in sequence and the result of one sub function is used in the next sub function. A design based around the iterative approach is shown in below figure. There are seven logic circuit cells each cell accepts one code word digit and the output from the preceding cell. The cell produces one output, Z, which is a 1 whenever the number of 1s on the two inputs is odd. Hence successive outputs are a 1 when the number of 1s on inputs to that point is odd and the final output is a 1 only when the number of 1s in the whole code word is odd as required. To create an iterative design, the number of cells and the number of data inputs to each cell need to be determined and also the number of different states that must be recognized by the cell. The number of different states will define the number of lines to the next cell (usually carrying binary encoded information). The fourth proposal was reviewed by Douglas Lewin and David Protheroe published in (1992, pg. 369),titled Design of Logic systems, in this book, according to them, iterative networks were widely used in the early days of switching systems when relays were the major means of realizing logic circuits. these technique fell into disuse when electronic logic gates widely available. It is possible to implement an arbitrary logic function in the form of an iterative array, the technique is most often applied to functions which are in the sense ‘regular in that the overall function may be achieved by performing the same operation up to a sequence of a data bits. Iterative cell techniques are particularly well suited to pattern recognition and encoding and decoding circuits with large numbers of parallel inputs. The method is also directly applicable to the design of VLSI circuits and has the advantage of producing a modular structure based on a standard cell which may be optimized independently in terms of layout etc. Circuits containing any number of input variables can easily be constructed by simply extending the network with more cells. they examine the iterative circuits with some examples, although it is possible to implement an arbitrary logic function in the form of an iterative array, the technique is most often applied to functions which are in this sense ‘regular in that the overall function may be achieved by performing the same operation upon a sequence of data bits. Suppose a logic system could be decomposed into a number of identical subsystems; then if we could produce a design for the subsystem, or cell, the complete system could be synthesized by cascading these cells in series. Problem Reduced: this problem now has been reduced to that of specifying and designing the cell, rather than the complete system. The fifth proposal presented by Brians Holdsworth published in (1993, pg. 165-166) titled Digital Logic Design, stated that iterative networks widely used before the introduction of electronic gates are again of some interest to the logic designers as a result of developments in semiconductor technology. Moss pass transistors which are easily fabricated are used in LSI circuits where these LSI circuits require less space and allow higher packing densities. One of the major disadvantages of hard-wired iterative networks was the long propagation delays because of the time taken for signals to ripple through a chain of iterated cells. This is no longer such a significant disadvantage since of the length of the signal paths on an LSI chip are much reduced in comparison with the hard-wired connections between SSI and MSI circuits. However, the number of pass transistors that can be connected in series is limited because of signal degradation and it is necessary to provide intercell buffe rs to restore the original signal levels. One additional advantage is the structural simplicity and the identical nature of the cells which allows a more economical circuit layout. A book proposed by Brians Holdsworth and R.C. Woods published in (2002, pg.135), titled Digital Logic Design, in this book, the discussion on the structure has made and stated that iterative network consists of number of identical cells interconnected in a regular manners as shown in figure with the variables X1.Xn are termed as primary input signals while the output signals termed as Z1Zn and another variable is also taken a1an+1 are termed as secondary inputs or outputs depending on whether these signals are entering or leaving a cell. The structure of an iterative circuit may be defined as one which receives the incoming primary data in parallel form where each cell process the incoming primary and secondary data and generates a secondary output signal which is transmitted to the next cell. Secondary data is transmitted along the chain of cells and the time taken to reach steady state is determined by the delay times of the individual cells and their interconnections. According to Larry L. Kinney, Charles .H and Roth. JR, published in (2004, pg.519) titled Fundamentals of Logic design, in this book they discussed that many design procedures used for sequential circuits can be applied to the design of the iterative circuits, they consists of number of identical cells interconnected in a regular manner. Some operations such as binary addition, naturally lend themselves to realization with an iterative circuit because of the same operation is performed on each pair input bits. The regular structure of an iterative circuit makes it easier to fabricate in integrated circuit from than circuits with less regular structures, the simplest form of a iterative circuit consists of a linear array of combinational cells with signals between cells travelling in only one direction, each cell is a combinational circuit with one or more primary inputs and possibly one or more primary outputs. In addition, each cell has one or more secondary inputs and one or more secondary outputs. Then the produced signals carry information about the â€Å"state† of one cell to the next cell. The primary inputs to the cells are applied in parallel; that is, they are applied at the same time, the signals then propagate down the line of cells. Because the circuit is combinational, the time required for the circuit to reach a steady- state condition is determined only by the delay times of the gates in the cell. As soon as steady state is reached, the output may be read. Thus, the iterative circuits can function as a parallel- input, parallel-output device, in contrast with the sequential circuit in which the input and output are serial. One can think of the iterative circuits as receive its inputs as a sequence in time. Example: parallel adder is an example of iterative circuits that has four identical cells. The serial adder uses the same full adder cell as he parallel adder, but it receives its inputs serially and stores the carry in a flip-flop instead of propagating it from cell to cell. The final proposal was authored by JOHN F WAKERLY, published in (2006, pg. 459, 462, 756), titled Digital Design Principles, in this book he quoted that, iterative circuits is a special type of combinational circuits, with the structure shown in below figure. This circuit contains n identical modules, each of which contains both primary inputs and primary outputs and cascading inputs and cascading outputs. The left most cascading inputs which is shown in below figure are called boundary inputs and are connected to fixed logic values in most iterative circuits. The right most cascading outputs are called boundary outputs and these cascading output provides important information. Iterative circuits are well suited to problems that can be solved by a simple iterative algorithm: Set C0 to its initial value and set i=0 Use Ci and Pli to determine the values of P0i and Ci+1. Increment i. If i In an iterative circuit, the loop of steps 2-4 is â€Å"unwound† by providing a separate combinational circuit that performs step 2 for each value of i. Each of the works reviewed makes an important contribution to improve the disadvantages and problems by iterative circuits, which is lead to improving the iterative circuits, thus it is appealing me to pursue an investigation on the sequential circuits for better understanding about the iterative circuits CHAPTER 3 3. OVERVIEW OF DESIGN METHODS FOR ITERATIVE CIRCUITS 3.1 Iterative design Iterative design is a design methodology based on a cyclic process of prototyping, testing, analyzing, and refining a product or process. Changes and refinements are made, in the most recent iteration of a design, based on the results of testing. The quality and functionality design can be improved by this process. The interaction with the designed system is used as a research for informing and evolving a project, as successive versions in Iterative design. 3.2 Iterative Design Process The iterative design process may be applied throughout the new product development process. In the early stages of development changes are easy and affordable to implement. In the iterative design process the first is to develop a prototype. In order to deliver non-biased opinions the prototype should be examined by a focus group which is not associated with the product. The Information gained from the focus group should be integrated and synthesized into next stage of iterative design. This particular process must be recurred until an acceptable level is achieved for the user. Figure 3.1 Iterative Design Process 3.3 Iterative Circuits Iterative Circuits may be classified as, Combinational Circuits Sequential Circuits. Combinatorial circuit generalized using gates has m inputs and n outputs. This circuit can be built as n different combinatorial circuits, apiece with exactly one output. If the entire n-output circuit is constructed at once then some important sharing of intermediate signals may take place. This sharing drastically decreases the number of gates needed to construct the circuit. In some cases, we might be interested to minimize the number of transistors. In other, we might want a little delay, or we may need to reduce the power consumption. Normally a mixture of such type must be applied. In combinational logic design, the technique of expressing oral statements for a logic circuit in the form of a truth table is inadequate. For a simple network, a terminal description will often suffice, but for more complex circuits, and in particular when relay logic is to be employed, the truth method can lead to laborious and inelegant solutions. Iterative cell techniques are particularly well suited to pattern recognition and encoding and decoding circuits with a large number of parallel inputs, circuits specification is simplified and large variable problems reduced to a more tractable size, this method is directly applicable to the design of VLSI circuits. It should be pointed out though that the speed of the circuit is reduced because of the time required for the signals to propagate along the network; the number of interconnections is also considerably increased. In general, iterative design does not necessarily result in a more minimal circuit. As the advantage of producing a modular structure, circuits containing any number of input variables can be easily constructed by simple extending the networks with more cells. Suppose for example a logic system could be decomposed into number of identical sub subsystems, then if we would produce a design for the subsystem or a cell the complete system could be synthesized by cascading these cells in series. The problem has now been reduced to that of specifying and designing the cell, rather than the complex systems In general, we define a synchronous sequential circuit, or just sequential circuit as a circuit with m inputs, n outputs, and a distinguished clock input. The description of the circuit is made with the help of a state table with latches and flip-flops are the building blocks of sequential circuits. The definition of a sequential circuit has been simplified as the number of different states of the circuit is completely determined by the number of outputs. Hence, with these combinational circuits we are going to discuss a normal method that in the worst case may waste a large number of transistors For a sequential circuit with m inputs and n outputs, our method uses n D-flip-flops (one for each output), and a combinatorial circuit with m + n inputs and n outputs. 3.4 Iterative Circuits-Example An iterative circuit is a special type of combinational circuit, with the structure shown, The above diagram represents the iterative circuits and this circuit contains ‘n identical modules each of which has both primary inputs and outputs and cascading inputs and outputs. The left most cascading inputs are called boundary inputs and are connected to fixed logic values in most iterative circuits. The right most cascading outputs are called boundary outputs and usually provide important information. Quiet often in combinational logic design, the technique of expressing oral statements for a logic circuit in the form of truth table is inadequate. Iterative circuits are well suited to problems that can be solved by an algorithm i.e iterative algorithm Set C0 to initial value and set i to 0. Use Ci and Pli to determine the values of P0i and Ci+1. Increment i. If i In an iterative circuits, the loop of steps 2-4 is â€Å"unwound† by providing a separate combinational circuit that performs step 2 for each value of i. 3.5 Improving the testability of Iterative Circuits As stated by A.Rubio et al, (1989, pg.240-245), the increase in the complexity of the integrated circuits and the inherent increase in the cost of the test carried out on them are making it necessary to look for ways of improving the testability of iterative circuits.The integrated circuits structured as iteration of identical cells, because their regularity have a set of advantages that make them attractive for many applications. Among these advantages are their simplicity of design, because the structural repetition of the basic cell, manufacturing, test, fault tolerance and their interest for concurrent algorithmic structure implementation. Here in this journal we also study about the testability of iterative circuits the below figure illustrates the typical organization of an N-cells iterative unidimensional circuit (all the signals go from left to right); however the results can be extended to stable class of bilateral circuits. The N cells have identical functionality. Every cell (i) has an external input yi and an internal input xi coming from the previous cell (i-1). Every cell generates a circuit output signal yi and an internal output xi that goes to the following cell (i+1).The following assumptions about these signals are considered below All the yi vectors are independent. Only the x1, y1, y2.yn signals are directly controllable for test procedures. Only the y1, y2 yn signals are directly observable. The xi and ^xi signals are called the states (input and output states respectively) of the ith-cell and are not directly controllable (except xi) neither observable (except xn). Kautz gives the condition of the basic cell functionality that warrants the exhaustive testing of each of the cells of the array. These conditions assure the controllability and observability of the states. In circuits that verify these conditions the length of the test increase linearly with the number of cells of the array with a resulting length that is inferior to the corresponding length for other implementation structures. A fundamental contribution to the easy testability of iterative circuits was made by Freidman. In his work the concept of C-testability is introduced; an iterative circuit is C-testable if a cell-level exhaustive test with a constant length can be generated. This means the length is independent of the number of cells composing the array (N). The results are generalised in several ways. In all these works it is assumed that there is only one faulty cell in the array. Cell level stuck-at (single or multiple) and truth-table fault models are considered. The set T of test vectors of the basic cell is formed by a sequence (what ever the order may be) of input vectors to the cell. Kautz proposed the cell fault model (CFM) which was adopted my most researchers in testing ILAs. As assumed by CFM only one cell can be faulty at a time. As long as the cell remains combinational, the output functions of the faulty cell could be affected by the fault. In order to test ILA under CFM every cell should be supplied with all its input combinations. In Addition to this, the output of the faulty cell should be propagated to some primary output of the ILA. Friedman introduced c-testability. An ILA is C-testable if it can be tested with a number of test vectors which are independent of the size of the ILA. The target of research in ILA testing was the derivation of necessary and sufficient conditions for many types of ILAs (one dimensional with or without vertical outputs, two-dimensional, unilateral, bilateral) to be C-testable. The derivations of these conditions were based on the study of flow table of the basic cells of the array. In the case of an ILA which is not C-testable modifications to its flow table (and therefore as to its internal structure) and/or modifications to the overall structure of the array, were proposed to make it C-testable. Otherwise, a test set with length usually proportional to the ILA size was derived (linear testability). In most cases modifications to the internal structure of the cells and/or the overall structure of the ILA increase the area occupied by the ILA and also affect it performance. ILA testing considering sequential faults has been studied, sequential fault detection in ripple carry adders was considered with the target to construct a shortest length sequence. In sufficient conditions for testing one dimensional ILAs for sequential faults were given. It was not shown that whenever the function of basic cell of an ILA is bijective it can be tested with constant number of tests for sequential faults. To construct such a test set like this a procedure was also introduced. The following considerations from the basis of our work. Many of the computer aided design tools are based on standard cells libraries. While testing an ILA, the best that can be done is to test each of its cells exhaustively with respe

Al Capone :: essays research papers

The Rise and Fall of Al Capone Alphonse Capone was born in New York City by two parents Gabriel and Teresa Capone. Capone's parents immigrated to the United States in 1893 from Naples, Italy. Capone came from a large family and was the fourth oldest of nine children. (Kobler 10). As a child, Capone was very wise when it came to living on the streets of New York. He had a clever mind when it came to knowing his environment. Capone was not very bright when it came to school. Capone was an illiterate. He came from a poor neighborhood in Brooklyn, so education was not a priority. At about the age of eleven Capone became a member of a juvenile gang in his neighborhood. Al Capone's philosophy was that laws only applied to people who had enough money to live by them.   Ã‚  Ã‚  Ã‚  Ã‚   The name of the gang Capone became a member of was called the â€Å"Bim Booms† gang. In this gang, Capone was taught how to defend himself with a knife, and with a gun. By the time Capone reached the sixth grade he had already become a street brawler. Capone never responded well to authority and for this very reason his schooling would soon come to an end. While attending school, Capone was responsible for beating a female teacher and knocking her to the ground. The principal of the school rushed in and punished young Capone and for this very reason he would never return to school again. (Sifakis 603) After dropping out of school, Capone took up jobs such as working as a pin-setter at a bowling alley, and working behind the counter at a candy store. Capone was terrific at pool, winning every eightball tournament held in Brooklyn. He also became an expert knife fighter. Although the â€Å"Bim Booms† gang was the first gang Capone ever entered, he was quickly picked up by the â€Å"Five Pointers†. The â€Å"Five Pointers† was the most powerful gang in New York city. The gang was headed by Johnny Torrio, and was made up of over 1,500 thugs who specialized in burglary, extortion, robbery, assault, and murder. While working as a strong arm enforcer under Torrio, Capone learned all the lethal tricks that would help him reach a pinnacle point in organized crime. Capone was very grateful to Torrio. Torrio first set Capone out to do all of his â€Å"dirty work†.

Case Study on Pregancy Pain :: essays research papers fc

Case Study #7 A pregnant (5 mo.) woman is reporting pain and an enlargement in her lower right quadrant comes to seek advice on different ways of imaging the area without endangering her baby. What do you explain and advise?   Ã‚  Ã‚  Ã‚  Ã‚  I would also ask questions as to whether or not she is suffering from any other symptoms. Ordering blood and urine work on her is also an excellent idea. In Amanda’s case study she suggested the pelvic ultrasound. I would take it even a bit further. It is called a â€Å"transvaginal ultrasound†.   Ã‚  Ã‚  Ã‚  Ã‚  I would explain to her the benefits and/or risks of using this remarkable device. The ultrasound has been around since the 1950s and is considered safe and non-invasive. However, a transvaginal ultrasound is. (3) Transvaginal ultrasound is a method of imaging the genital tract in women. The ultrasound machine sends out high-frequency sound waves, which bounce off body structures to create a picture. With the transvaginal technique, the ultrasound transducer (a hand-held probe) is inserted directly into the vagina and is, therefore, closer to pelvic structures than with the conventional transabdominal technique (with the probe on the skin of the abdomen), providing superior image quality. This test can be used during pregnancy. A transvaginal ultrasound takes it a bit further than a regular pelvic ultrasound. In this way, it rules out things like ectopic pregnancy, ovarian cysts, fibroid tumors and other abdominal/pelvic diseases like PID (pelvic inflammatory disease). The transvaginal ultrasound is even better than the pelvic ultrasound. Doing her ultrasound this way will better pick up any potential problems too small enough for the pelvic ultrasound to catch. I would prefer it this way myself. Ovarian cysts occur when there is a lot of fluid swelling inside the ovary. However, they usually will dissolve on their own. If an ovarian cyst does not dissolve after the next 1-2 menstrual cycles, the doctor would usually try to monitor their activity. If it enlarges, the doctor may suggest removal of the cyst(s). (1) Fibroid tumors are usually benign (non-cancerous) tumors found, most often, in the uterus of women in their 30's and 40's, although they occasionally develop on other organs which contain smooth muscle cells. Fibroid tumors are solid tumors, which are made of fibrous tissue, hence the name 'fibroid' tumor. Most often fibroids occur as multiple tumor masses, which are slow-growing and often cause no symptoms. The size of fibroids varies immensely among women and some are so small that a microscope is required to see them.

Physical books Essay

The answer to this question is a simple yes. We shall prove in our discussion why we have chosen this answer. With advances in technology the word ‘paper’ no longer implies a material made of cellulose pulp, derived mainly from wood. As we make further advances, we see that the definition of paper has changed. Physical books that were made of paper have morphed into digital copies called e-books that are available over various mediums of communication such as the Internet or even our very mobile phones. We know that everything has a certain shelf life and if continue to use it beyond that period we will cause ourselves harm, this is also true for physical paper books, time has come to move over the paper books and to enter the world of e-books. Two of the most important factors supporting the cause of the e-book are that it saves: 1. Time and 2. Money 1. Time: In this rapid moving world we are all constantly on the move and we require information immediately, with e-books we can find the information we want immediately. Money: We all want to save money; e-books will be available at only a fraction of the price of the paper books since it will be cheap for the publishers to produce and this benefit will in turn be passed on to the consumer. Reasons for decline of paper books and the popularity of e-books are obvious: 1. E-books can be view almost instantaneously: One can browse through the thousands of e-books available on the Internet by just typing the keywords and purchase the e-book we want by using our credit cards and download the e-book immediately, thus we are saving a lot of overhead costs. 2. E-books cheaper for the publisher to publish as various overhead costs are minimized: Various overheads costs such as huge and expensive printing machinery and their maintenance will disappear; also there will not be need of a large work force to manufacture e-books. 3. E-books cheaper for the consumer to purchase than physical paper books: Since the manufacturing costs of the publishers will be minimized, this will be passed down to the consumer. Thus the consumer will enjoy great savings. 4. E-books can reach a much larger audience worldwide: E-books can be launched instantaneously through out the world; there will be no waiting to buy our copy of the e-book. Also many times a physical paper book is not available in all parts of the world, but this will not be a problem with e-books. 5. E-books are environment friendly: Unlike physical books made from paper, which is derived from timber, e-books don’t need the resources of nature to be made. Thus we will be saving thousands of trees every year and thus reducing the greenhouse effect and making the earth a green place to live in. 6. We can have thousands e-books in our digital device: We can literally have thousands of e-books in our digital device such as a laptop or a computer. The number of e-books is only limited by the storage capacity of our computer or laptop. This is impossible with physical paper books. Can you imagine a person moving around with a library of paper books? But we can move around with our library of e-books on our laptop anywhere! Conclusion: We as humans should be ready to accept the change of books from the physical to the virtual. Are we truly ready to leave the paper copies of the great novels and instead view them as e-books? Some have even said that if we do this we’ll be disrespecting the great authors and poets, but as we wait, the world around us rapidly changing. In the end we may have no choice but to accept the e-book as it gains popularity and following every passing day. This it’s only a matter of time before the paper books are replaced by e-books. Thus we have observed and noted from the above examples that the books made of paper are on their way out and the time of the e-book has arrived. (Sam Kleinman 2007) Works Cited 1.

Shortage of Water in Pakistan

Shortage of water in Pakistan As we all know, Pakistan is facing severe shortage of water. There are two main reasons, one due to persistent droughts—which is beyond the control of a man, and the other due to miss-management of water resources. Impact on economy / society * Less water means less agricultural yields, meaning they cannot fulfill the food requirements of the nation, so they need to be dependent on other countries.
