Quantitative Techniques - Essay Example The social and economic scenario is in the constant process of undergoing change and is influenced by a number of external factors. As such, there are numerous controllable and uncontrollable parameters that today’s decision makers need to take care of in order to prepare a careful course that can navigate through all idenfied obstacles. If adopted, qualititative, well-structured and a well-planned business forecasting effort can yield the desired results. As such, apart from feeling the need to forecast, it is also very important to plan the forecasting process with great precision (John E. Hanke, Arthur G. Reitsch, 1989). The rise in the growth and use of computing power to perform calculations has gained immense popularity among users. As such, with a good forecasting plan, one can easily perform the required analysis in a short time. Forecasting is used to identify a number of patterns that are deemed important to a company’s interests. It could include attributes such as the performance of stocks over a time period, pattern of sales, prices of essential raw materials, employee satisfaction surveys etc. a company can immensely benefit from business forecasting as these enable it to analyze its performance across various domains and also helps it compare itself amongst other competitors in the market. It enables the company to identify the segments that are not performing according to expectations and paves the way for adopting suitable solutions to overcome them. As the economy is dynamic in nature, there is an ncreasing need to prepare the future map in advance, which emphasizes the need fo r business forecasting. In the recent years, business forecasting has adopted an extensive scientific flavor that includes the fusion of various business theories and techniques to forecast specific types of data. It can involve procedures as simple as spreadsheets to massive database networks that are performing trillions of

Analog Circuit Computer Aided Design (CAD) Essay

Analog Circuit Computer Aided Design (CAD) - Essay Example This section deals with the existing literatures related to analog circuit optimization. It outlines a summary of all the resource materials, authorial credentials, content credibility, source credibility, text credibility- Fluid integration of the source evaluation. A true literature review gives the proper sense of works that technology has achieved till date into that specified topic which helps one researcher to bring down his own research problem. Han Young et al. (1990) developed an analog silicon compilation system for CMOS op amps (OPASYN). The synthesis starts from a certain specification. From its database, program selects op amp topology that suits most with the given specification. Using parametric optimization the circuit then determines optimal value for its parameters. It also produces Design-Rule-Correct compact layout of the optimized op amp. Yang et al. (1995) proposed a Simulated Annealing (SA) algorithm for topology selection and sizing. In analog cells, topology choice and sizing simultaneously is efficient than normal two step mode synthesis. Basic problem with that approach is that super circuits must be worked out for each sort of analog cells. Chen et al. (2000) placed an iterative optimization idea for improving delay in digital circuit. Instead of only adjusting that gate sizes to reduce delay, they adjusted wire loads of the gates by repositioning them using geometric program. It gave better result in deep sub-micron design where the effect of interconnect delays dominates Mandal P and Visvanathan V (2001) devised an efficient technique for sizing of op amp by sequential convex optimization problem. This method then prototyped in MATLAB to apply into CMOS two stage op amp.

A Christmast Surprise for Gramma Essay Example for Free

A Christmast Surprise for Gramma Essay A Christmas Surprise for Grandma by Gloria J. Shuttleworth Grandma lived on Sugar Creek Mountain all alone. It was a beautiful mountain, with tall cedar trees all over the mountain top. In the middle of the mountain was a crystal clear lake. The water in the lake was the prettiest blue youve ever seen. When the water was calm, you could see the fish swimming around in the lake. I loved sitting by the lake when I was a little girl. Grandma would pack us a lunch, and we would sit at the lake for hours on end. Hour after hour, grandma would tell me stories about her life on the mountain. I remember the day that grandpa drowned in the lake. My parents had tried to talk grandma into moving into town, but she wouldnt hear of it. My parents knew not to argue with her, because they knew that grandma was set in her ways. Ive been on this mountain for so long that Ive forgotten which is the oldest, me or the mountain, grandma had said, with a twinkle in her eyes. I knew my parents worried about her being alone, because grandma was the only person who lived on Sugar Cliff Mountain. Today I was going to visit grandma, and the excitement grew inside me at the thought of spending time on the mountain once more. After all, it had been ten years since I had seen grandma. Its hard to believe that my career had kept me away for so long. As I approached the top of the mountain, I could see grandma staring out the window of her little log cabin home. Grandma greeted me at the door with a big hug. I am so happy that you could come to visit with me, said grandma. This Christmas is going to be so wonderful! I have a special surprise for you dear. Little did grandma know that I had a very special surprise for her as well. Well, we cant stand around here all day, said grandma. Theres a lot of work to get done. I have invited the people from the village to come to my Christmas party on Saturday evening. After I had freshened up a bit, we spent the day baking all sorts of cookies and candies. Grandma had a story to tell as we baked the goodies for the party. She told me about how she used to bake apple pies for grandpa. He loved apple pies, said grandma. Those were his favorite. She said that after the pies would cool off, that grandpa would send her into the living room, under the pretense that he would clean up the kitchen. Grandma knew what he was really up to, but she never let on that she knew. Grandma would go into the living room and sit in her rocking chair. She would sing some of the songs that she knew grandpa loved. About an hour later, grandma would wander back into the kitchen. Why Henry! she said kitchen, grandma retired for the evening. I made myself a cup of tea and sat down in front of the fireplace. Sitting alone in the quiet house, I pondered my childhood memories of my grandparents. They had always been such a fun loving and happy couple. Shortly after they were married, grandpa built the log cabin home for his Little ole Emmy, as he called her. Just before Christmas, almost twelve years ago, grandpa was outside gathering firewood, when grandma heard a horrible scream and a terrible noise. She ran outside to find that an area of the ice on the lake had fallen through. She yelled for grandpa over and over but no reply ever came. They searched the lake for over a week, but no trace of grandpa could be found. Finally, they called off the search. One of the men who had helped in the search said theyd probably never find grandpa now. Just then, as my thoughts were still racing around in my head, my grandmother brought me back to reality. We have to be up very early in the morning dear, so off to bed now, she said. I slowly walked to my grandmothers room, and kissed her goodnight. Morning came early at grandmas house. As I entered the kitchen I could smell the homemade biscuits and gravy cooking on the stove. Whats on our list of things to do today? I asked. The men are coming from the village this morning to put the lights on the trees, and we have lots of presents to wrap for the children, she said. Just then, there was a knock at the door. It was the men from the village ready to start putting up the lights. Grandma was so excited as she stepped back to watch them. Lets wrap those presents now Laura, said grandma. As I watched grandma wrap the presents and tie the ribbons, I knew that so much more was being placed around them. With each piece of wrapping paper grandma was also wrapping them with love. After the last present was wrapped, we realized that wed been wrapping presents all day! It was now getting dark outside and grandma wanted to go outside to view the lights. As we stepped out onto the porch, we gasped. The sight that met our eyes was so beautiful to behold! The snow was glittering and the reflection of the lights on the snow was beyond words! It was breathtaking! That night I went to bed with a heart full of love for my grandmother. I knew that someday I wanted to be just like her, full of love for others. Saturday evening the village people started arriving just after dark. Grandma always waited until evening to have her Christmas party, because she loved the lights. All the guests gathered around in the front yard and began to sing Christmas carols. Oh, how grandma loved that! Ole Ben was a jolly fellow who worked at the village store, and he was chosen to help Santa hand out the presents. The children shouted with glee, as they unwrapped their gifts. Grandma said, Laura, come here dear, I have a surprise for you. As she handed me the present, I could see the love and pride in her eyes. I love it grandma, I said, as I bent down to kiss her cheek, I will cherish it forever. Grandma had made a quilt out of some of my dresses that I had worn as a little girl. Grandma, if you could have just one special gift for Christmas, what would it be? I asked her. Without even stopping to think, she replied, I would like t o see your grandfather just one more time, so I could feed him the apple pie that the horses quit snatching when he left us. Just then grandmas face lit up like the lights on the Christmas tree! Everyone turned to see what grandma was looking at. Walking slowly toward her, with an apple pie in his hand, was grandpa! There was two slices missing from the pie that he was holding. The village people were speechless, as they thought they were seeing a ghost. Grandpa chuckled, as he yelled out, Emmy, those darn horses snatched the pie and got away with two pieces. Difference to me, but slowly my memory started to return. I remember now going out to gather firewood. There was a nice piece of wood on the lake. I thought the lake was frozen over so I stepped out on the lake to get the piece of wood. I remember hearing the lake crackle and thats the last I remember about the accident. Laura, how can I ever thank you for bringing grandpa home to me? asked grandma. Laura replied, Seeing the happiness and the love you have for each other is all the thanks I need. As Laura retired to bed that night, she couldnt help but think about the surprise that she had given to grandma for Christmas. She knew in her heart that it was the best surprise present that grandma would ever get. What a warm and wonderful feeling came over Laura as she fell asleep, thinking of her grandparents.

Company Law and the Corporate Veil

Company Law and the Corporate Veil Introduction As the day company is formed, it can be said that the company is â€Å"incorporated†. As the company uniqueness is that it provides for effective separation of resources and managements of its resources and it is further compounded on the fact that the owner of the capital can limit his or her liability to the third parties. Therefore the company is recognized as a separate entity and it is treated in its own capacity. In nowadays business companies, it can be seen that companies have both advantages and disadvantages in measuring the limited liability of the shareholders on the basis that the company is liable for its debts and obligations. Therefore, double-edged sword is created which means it has both good and bad elements. In this assignment, details about the doctrine of separate legal entity will be analyzed. Also statements of features of company as separate legal entity and circumstances the veil of incorporation will be lifted will be analyzed with reference to some cases. Doctrine of separate legal entity In company law of Malaysia, a company is treated as a separate legal entity from its members constituted in it which is its shareholders and directors. This is the doctrine of separate legal principle. The company is a different separate body from its member. Thus, the members of the company are not liable for the company debts. For instance, when a company turn into a contract, the company itself will personally liable for the contract rather than the shareholders and the directors. Therefore, a company is a corporate body. A corporation is an artificial legal person that exists independently of the individuals who at any given time are the members of the corporate body. This principle was established by the House of Lords in Salomon v Salomon Co Ltd[1]. The rule of Agency An agency is a relationship where one person consents or is deemed to have consented that the other person should act on its behalf so as to affect its relations with third parties. Features of Separate Legal Entity At the time the company is incorporated, it is a separate legal person, it brings forth some effect which can be the features of it. Under section 16(5) of the Companies Act 1965 states that, once a company had been incorporated, the company had all the ability as an incorporated company. For instances, it is means that the company can enjoys its right and function as a legal person. Company that incorporated is a legal personality that is created and recognized by the law as stated by Salleh Abbas F.J in Tan Lai v Mohamed bin Mahmud. When a company register under Companies Act, it becomes vested with corporate personality which is an independent legal person and separate from its members. For instance, the company is a legal person. In Salomon v. Salomon Co. Ltd. (1987)[2], unsecured creditors claimed that the company never had an existence of independent although it was incorporated. They claimed that it was Salomon himself trading under another name, but the House of Lords held Salomon Co. Ltd. must be regarded as an independent person from Salomon. This is because of the fact that the company was not role as an agent for the member. Thus, Salomon and the others are mere subscribers of the company although he owned all the issued shares. Hence, Salomon could enforce its rights against the company as a secured creditor. Furthermore, the company also has the ability to sue and be sued in its own name. Therefore, a company can make legal action to enforce its right. It was established in the case Foss v Harbottle[3] where action brought by the members of the company made an injury complain towards the company and it was fail. Therefore the member could not take action on behalf of the company. Besides, a company has perpetual succession which means members may join and leave, but the company will continue go on. When a company become incorporation, it will continue operate until it is dissolved according to the Companies Act 1965. Under the case of Re Noel Tedman Holdings Pty Ltd[4], the court allowed the representative personal of the deceased to appoint the directors of the company so that the directors could allow the transfer of the shares to child. This proves that although the shareholders had leave but the company is still exiting and continue go on. Other than that, a company also has ability to own property on its own name. According to section 16(5) a company has power given to own personal land and other types of property. While company is separate legal person from its member, the member has no legal right and interest with the property and it is belongs to company. In case Macaura v Northern Assurance Co. Ltd[5], Macaura owned a tree plantation which was covered by an insurance policy. Later he sold the plantation to a company which he was the only shareholder. After the sale, Macaura continued to insure the plantation in his own name. A fire broke out and the plantation was destroyed. Macaura then attempted to claim on the insurance policy but the insurance company refused to pay. The issue was whether Macaura had an insurable interest at the time of the loss. It was help that the insurance company was right in not paying. The plantation company was a legal entity in its own right, separate from its shareholders. Other than that, in a corporate body, the shareholders of the company can enjoy limited liability. While a company is a separate legal entity, the shareholders are not liable for the debts and the liability is limited by shares. Therefore, creditors have no rights to take any legal action against the shareholders. In case Ye Yut Een 1978[6], the director of the company is not liable for the company’s debt. It is the company who had not complied with the procedures related to the retrenchment benefits. Lifting The Veil of Incorporation Although the company has privilege as separate legal entity, it must not be used for any unlawful or illegal business purposes, in case a fraudulent or dishonest use is made of the legal entity, the concerned individuals will not be allowed to take the shelter of the corporate personality. The court will disregard the corporate veil to see the real persons behind it. Generally, the law will not go behind this veil of incorporation to look at the membership of the company. But the courts will ‘lift the corporate veil’ in some exceptional cases. Salomon v Salomon Co Ltd case have decided that the members of the company are not liable for any contract that contracted by the company. This will cause they may have a chance hiding behind the veil to defraud the creditors and other parties that contracted with the company. The court will pierce the corporate veil by applying the principle known as ‘piercing the corporate veil’. When there is no entity separate from members, the court will pierce the corporate veil and take action. After that the court will make the company and its members liable for any breach of contract. The veil of incorporation can be lifted in according to situation provided under statutory provision and by judicial interpretation under the common law. For instance, section 36, Companies Act 1965 states that if the number of members of a company is reduced to below two and its carries on business more than six months, the person who is a member of the company during the time that is so carries on business after those six months, and is aware of it, the person is personally liable for all the debts that the company contracted after those six month and he may be sued therefor. According to the section 304(2), Companies Act 1965, together with the section 303(3), provide that an officers who knowingly contract a debts on behalf of the company. It means borrow money and knowing that that the company is most likely unable to pay the debt is guilty of an offence and on conviction be made personally liable to pay that debt. Under section 304(1), Companies Act 1965 provides that when a company’s intention is to purposely defraud its creditors, the veil of incorporation is lifted. In the course of the winding up of a company or in any proceedings against a company it appears to the court when hearing the application of the liquidator or any creditor or contributory of the company that any business of the company has been carried on with intent to defraud creditors of the company or creditors of any other person or for any fraudulent purpose, the court may hold any persons who were knowingly parties to the fraud personally responsible for all or any of the debts or other liabilities of the company as the court directs. Under section 365(2), Companies Act 1965 provides that any payment of dividend not from profit is prohibited. Any payment made of dividends to shareholders is personally liable by the director towards the creditors of the company when there are no profits available. There are also situations where the court thinks it is appropriate and it will lift the veil of incorporation at common law. The situation whereby the veil of incorporation is lifted where the company is acting as agent or partner of the controlling or parent company. Group of the companies the problems can be complex. Subsidiary own and fund money of a business has been held to do so as agent for the holding and parent company. So, holding and parent company actually operating business. This is applied in case Smith, Stone and Knight Ltd v Birmingham Corporation (1939)[7]. Besides, the veil of incorporation will be lifted when there is a group of companies, including holding and subsidiary company, the court can lift the veil and treat a company and its subsidiary as one economic unit. In case DHN food Distributors Ltd v Tower Hamlets London Borough Concil[8], subsidiary company owns a piece of land while the DHN which is parent company operated the business on the land. The local authority purchases the said land. The DHN claimed compensation for disruption. The local authority refused to pay the compensation on the grounds that the land did not belong to DHN. The court lifted the veil of establish that DHN is connected with the subsidiary company as treated as one economic unit, they did suffer a loss as a result of acquisition from the local authority and allowed to claim the compensation. At last, lifting the corporate veil can also assist in the prevention of fraud. In case Aspatra Sdn Bhd Ors v Bumiputra Bank Malaysia Berhad (BBMB)[9], Lorrain Osman, one of the director of Aspatra Sdn Bhd, was once a director of Bumiputra Bank Malaysia Berhad, must account for the secret profit he made in breach the fiduciary duty. To avoid detection Lorrain Osman had channeled the monies which is the secret profit he make into several companies that he controlled, one is the Aspatra Sdn Bhd. BBMB feared that the money Lorrain Osman took would leave Malaysia and applied for an injunction. The veil lifted to reveal that the assets of Aspatra Sdn Bhd belong to the Lorrain Osman and the injunction was accepted. Conclusion In conclusion, it clearly stated that the doctrine of separate legal entity have created double-edged swords to the shareholders of the company. Although it brings many features to the shareholders but it also have drawback towards the company itself and creditors in some situation. Hence, there will be some defects of incorporation. However, lifting the veil of incorporation by the court will reduce the defects of incorporation.

YouTube’s Effect on the Music Industry Essay -- digital media, innovati

Digital media has had a vast effect on American society, and it continues to revolutionize the way things work. One of the main outlets for innovation in digital media is the website, YouTube. It has paved a way for the sharing of videos to a multitude of audiences. More specifically, it has profoundly affected the way the music industry works, by providing independent artists a way to release and share their music to a mass audience without the help of a major record label. Often called â€Å"The YouTube Effect,† it has become a phenomenon in the music industry. Bindu Swetha (2013) noted, â€Å"YouTube was launched in 2005 by former PayPal owners Chad Hurley, Steven Chen and Jawed Karim. Prior to YouTube, there was no website that enabled users to share their favorite videos on a website† (para. 1). The fact that YouTube was the first website to allow people to post and share videos is one of the reasons YouTube has had so much success. YouTube users can upload content to the site and share it for millions to see. Christopher Cayari (2011) found that, â€Å"YouTube has become the third most visited website in the world – behind Google and Facebook† (YouTube Has Affected Music section, para. 2). In October 2008, YouTube attracted 100 million American viewers a day, estimated to be over two-thirds of the Internet users in the United States (comScore, 2008). Cayari (2011) said that YouTube is a technology that challenges the way we perceive music, musician and audience (YouTube Has Affected Music section, para. 3). When you take a look at the number of musicians who have gained recognition simply by using YouTube, you can see the truth in Cayari’s statement.

The Hazard of Bulglarly Essay -- Papers

The Hazard of Bulglarly The hazard of burglary has significant impacts on people and the environment in which they live, and these can be identified easily. Consequently this hazard can be prevented and/ or managed effectively. A hazard is an event that affects or threatens people or property. Burglary is a common, frequently occurring hazard. Burglary is the unauthorised entry into a building as a trespasser in order to steal. An offence of burglary is recorded by the police if a person enters any building as a trespasser with intent to commit an offence of theft, rape, GBH, or unlawful damage. Burglary does not necessarily involve forced entry. The 2001 British Crime Survey (BSC) estimates that there were a total of 1,063,000 burglaries against domestic properties in the year 2000. The majority of burglaries occur in urban areas and are less frequent in rural areas. Burglary has many different types of impacts on people and the surrounding environment, these are not always easy to identify as people are reluctant to admit any emotional upset, especially males. One of these impacts is the cost of burglary. The mean cost of burglary in 1998 was  £1416. The factors that affect this cost the most are property stolen, damage to inside of property and damage to outside of property. Burglary also increases the cost of the individuals home insurance and if the problem is reoccurring the insurance premiums for the whole area will increase as a result of this. The most common goods to be stolen are electrical goods and cash, one of the main effects of burg... ...vents per dwelling in the SBD sample of 660. Finally marking property with a pen which can be read under ultraviolet light is an effective way of increasing the chance that stolen property may be returned to the owner if recovered by the police. Simple common mistakes are also a cause of burglary which can easily be prevented such as having large amounts of cash on display or within the property, leaving car keys on display and leaving doors unlocked. These can easily be avoided and will prevent a sneak-in burglar from easily removing expensive property such as cars. Overall burglary is a common problem which can be managed and even prevented by spending a small amount of money on security devices such as a burglar alarm and strong door locks. Increasing awareness of the problem also decreases burglary numbers.

The range of normal resting CO is between 4.2 L per minute and 5.84 L for these subjects. Did average CO increase, decrease, or not change with exercise? increase Discussion 1. What caused the change in HR with exercise? Muscles use more oxygen and  glucose from the blood with increased movement. This produces wastes that decrease blood pH below the normal range causing an increase in heart rate. The heart rate increase delivers blood to the lungs and kidneys more quickly so these organs can remove the wastes from the body. The faster the muscles use energy and create waste, the faster the heart must pump blood. 2. Discuss the effect of venous return and heart rate on exercise EDV. Exercise increases venous return by forcing your body to add and enlarge blood vessels. In addition to circulatory improvements, exercise helps muscles and tissues become conditioned to allow them to overcome the stresses of working out. During exercise, the body demands additional oxygen and requires removal of extra carbon dioxide increasing the heart rate. EDV is increased with exercise 3. What caused the change in ESV volume with exercise? ESV decreases with exercising so that there is less resistance for the blood to flow to increase cardiac output. 4. Why did SV change with exercise? SV increase during exercise because an individuals body needs more oxygen and nourishment that are both received from the pumping of blood. The level of increase of SV is also depends on the type of exercise 5. Discuss the importance of the change in CO with exercise? When the body is in rest cardiac output is lower as the demand in oxygen is low. During exercise heart rate and stroke volume increase which results in an increase in cardiac output 6. Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving supporting data from your experiment that supports your corrections. My prediction were correct Application 1. We measured the stroke volume of the left ventricle. What was the average stroke volume of the right ventricle at rest and after exercise? 69 resting 104 exercising 2. Assume that for one beat, the stroke volume of the left ventricle is greater than that of the right ventricle. Explain why in a normal heart this would be corrected on the next beat. blood would be transferred from your systemic circulation into you pulmonary circulation. Pressures throughout your pulmonary circulation would begin increasing. As soon as small amount of blood is transferred from the systemic to pulmonary circulation, the pressure in the pulmonary veins and left atrium increases a  little. This increases the filling of the left ventricle, and the resulting increase in its end-diastolic volume increases the stroke volume, correcting the problem 3. Explain why elite athletes have a lower than normal heart rate, yet have a higher than normal ability to increase cardiac output. An athlete has a larger stroke volume, which means a greater volume of oxygen is delivered to the body per heartbeat.They usually have larger heart that results in higher cardiac output, as more blood is pumped out with each beat. The raised cardiac output allows the heart to beat more slowly
