M1A3 - Organizatinal Behavior Research Paper Example | Topics and Well Written Essays - 750 words

M1A3 - Organizatinal Behavior - Research Paper Example In addition, mental models and shared vision become the third and fourth parts of the process respectively. The former are the personal assumptions within an individual about the company while the latter is the common goal shared by all members of staff9 (Sessa & London, 2006). Lastly, the team learning aspect becomes the fifth key pillar in this organization that is mainly the collective pooling of individually learnt aspects drawn from other members of staff (Marquardt, 2011). Objectively, this paper will give the name of a company in which transformation will aim at by including the intended broad principles. Further, it will include recommendations to the chosen learning organization that may include motivation, team management, culture, ethics, and empowerment. The learning organization chosen would be General Motors Corporation. Brief overview of General Motors General Motors is a name commonly associated to remarkable car brands in the world. Arguably, GM is the leading multi- state car manufacturer with its headquarters in Detroit, Michigan in the United States. Globally, it has establishments in a hundred and fifty seven countries spread across several continents. It has over two hundred thousand employees under its wing by either employing them directly or indirectly. GM has four regional clutters namely, GM South America, GM Europe, GM North America, lastly GM International Operations. Each of these segments is charged with organizing their designated world regions in sales, production, marketing, and development of products. The fifth and key pillar of the General Motors Company is the General Motors Financial that is in charge of the primary financial matters of the company. However, in June 2009 General Motors started experiencing financial strain (Kolb, 2011). The government of the United States intervened through the Chapter 11 accord in which the government-sought to protect the Company’s assets after bankruptcy declarations (Weston, 201 2). With this move, General Motors shareholders could not access their assets in Asia and Europe during this crisis. Remarkably, it experienced a relisting to the stock markets in 2010 following a successful public offering of preferred shares. Sequentially, the U.S Treasury let go of thirty-five percent of its shareholding rights to a minimum of twenty-six percent after the 2010 initial public share offer. Treasury had acquired this stake when it sought to save the company from economic plummet. GM as a transformed organization In order for GM to make substantial transformation, a number of aspects have to come in to play. For a start, the main reason that led to the economic fall of this market giant was the hefty allowances that it paid its managers during that time. The managers of the company across the globe took home unnecessary large pay, which the company struggled to effect. Therefore, the transformation process for this company would start by reevaluating the pay for its managers to suit the current economic times. Ideally, it is not morally up right to pay people heftily when a company as it its dismal performance. Secondly, the Company experienced economic struggle because of the high amounts of money that they injected in to the pension scheme for their retired

In western schools, these empires usually consist of empires such as Alexander the Great’s, the Roman Empire, and even the British Empire of the Victorian Age. These empires are all seen as major forces in the field of history, but there is often a great empire that has been overlooked. This overlooked empire once amassed about half of the world’s land. Its territories once included China, Persia, and even Eastern Europe. The empire is known as an empire that virtually had the world trembling in their boots. The empire is the Mongol Empire, and the question is how does an empire of nomads end up drastically changing the geography of the world and scaring the living daylights out of those who were in soon to be conquered areas.

Please note that this Assessment document has 3 pages and is made up of 3 Sections. Name: Section 1 – Understand why change happens in a business environment 1. Explain why change happens in a business environment. You should include at least three reasons in your answer. There are few factors which constantly pressure organizations to adapt and they force change in a business environment. We can apply here PEST acronym, it means that changes in business environment happen for political, social or technical reasons. Political changes are out of business’ control. They need to adapt to the all law changes. If not, they can even be prosecuted. Economic changes are dependable i.e. from the exchange rate due to its high influence on import and export. Economic change is also a change forced by a competition on the market. Products or services need to be competitive in price or/and quality, otherwise company will not prosper well. Social change comes from customer’s attitude and buying preferences. It can be shaped by media and big events. Technical change is forced by new technologies. To be competitive, and to be ahead of the competitors means, that company has to be up to date with modern solutions. Section 2 – Understand the purpose of supporting change in a business environment 1. Identify the main reasons for reviewing working methods, products and / or services in a business environment. Business environment is very changeable. Services or/and products have to be constantly efficient, so they have to be continuously reviewed. It ensures that company stays competitive and meets the targets. One of reasons of reviewing working methods is a change in a service/product. All related procedures need to be updated to be sufficient. Company has to make sure that all methods are updated and best possible from currently known. They has to agree with all standards. In ensures, that company is competitive and meet customers’ requirements. 2. When a business is going through change: a) Describe the different types of support that people may need. There are people, who can adapt to change really well and those, who can not. It is really important for company to make sure, that all employees feel comfortable with new changes. There are some universal ways of supporting people within a business change: Effective planning helps to avoid a chaos during the change. It shows all employees that everything was well planned and considered. Participation makes it easier to adapt. It is very important for team members to feel valued part of change. Clear communications and expectations. People have to be well informed and know what is happening, why and how things will look like after. Training or  retraining. There will be new work methods, new equipment, procedures. Employees need to receive training to be able to work effectively. Encouragement and other supportive behaviours are important for team members. Positive attitude is needed, smiling, encouragements and understanding. b) Explain the benefits of working with others. Working with others gives a wide range of different ideas and opinions. Different people will have different approaches to same problem. Different skills are brought to one project by all the team members. In time of change working with others may be really helpful, team members know each other and can help one another when it is necessary. When we do not work as a part of a team communication an relations get worse. The team is unsuccessful as well as individuals. Such a behaviour does not benefit anyone. Section 3 – Understand how to respond to change in a business environment 1. In relation to your current business environment (or one that you are familiar with): a) Explain why you should respond positively to changes in working methods. Changes happen for a reason and are unavoidable if a company wants to remain successful. It is very helpful to keep positive attitude in all this situation. Positive approach will help us to adapt faster and will influence other team members. Negative response will create difficult environment to work in by financing others in a bad way. b) Explain why you should respond positively to changes in products or services.

What Is Globalization

Globalization is a term that includes a wide range of social and economic variations. It can encompass topics like the cultural changes, economics, finance trends, and global market expansion. There ought to be positive and negative effects of globalization – it all comes as a package. Globalization helps in creating new markets and wealth, at the same time it is responsible for extensive suffering, disorder, and unrest. The great financial crisis that just happened is the biggest example of how negative globalization can turn. It clearly reveals the dangers of an unstable, deregulated, global economy. At the same time, this gave rise to important global initiatives, striving towards betterment. Globalization is a factor responsible for both repression and the social boom. What happens when there is a growing integration of economies across the globe? Majorly there have been positive impacts of this global phenomenon – through liberalization, privatization and globalization (LPG). Due to globalization, there has been significant flow of inward foreign direct investment. MNCs are getting a chance to explore various different markets across economies and explore the untapped potential. IMPACT OF GLOBALIZATION It was in July 1991, when foreign currency reserves had tumbled down to almost $1 billion; inflation was at a soaring high of 17%, highest level of fiscal deficit, and foreign investors loosing confidence in Indian Economy. With all these coupling factors, capital was on the verge of flying out of the country and we were on the brink of become loan defaulters. It was at this time that with so many bottlenecks at bay, a complete overhauling of the economic system was required. Policies and programs changed accordingly. This was the best time for us to realize the importance of globalization. MEASURE OF GLOBALIZATION Devaluation: The first initiative towards globalization had been taken the moment there was an announcement of devaluating the Indian currency by a hoping 18-19% against all the major global currencies. This was a major initiative in the international foreign exchange arena. The Balance of payment crisis could also be resolved by this measure. Disinvestment: The core elements of globalization are privatization and liberalization. Under the privatization scheme, bulk of the public sector undertakings have been/ and are still being sold to the private sector. Thus the concept of PPP (public private partnership) came up. Allowing Foreign Direct Investment (FDI): Allowing FDI inflows is a major step of globalization. The foreign investment regime has been quite transparent and thus the economy is getting boosted up. Various sectors were opened up for liberalizing the FDI regime. For successful globalization countries need to chalk out strategies and policies to open up the doors for the inflow of foreign direct investment (FDI). The FDI by the MNCs brings with it flow of foreign capital, inflow of technology’ real capital goods, managerial and technical skills and know-how. Globalization can easily promote exports of the country by exploiting its export potentials in a right way. Globalization can be the engine of growth by facilitating export-led growth strategy of a developing country. ASEAN countries such as Indonesia, Malaysia and Thailand have demonstrated their success of export-led growth strategy supported by the FDI under globalization approach. Globalization can provide sophisticated job opportunities to the qualified and also check ‘brain drain’ in a country. Globalization would provide varieties of products to consumer at a cheaper rate when they are domestically produced rather than imported. This would help in improving the economic welfare of the consumer class. Under globalization, the rising inflow of capital would bring foreign exchange into the country. Consequently, the exchange reserves and balances of payments position of the country can improve. This also helps in stabilizing the external value of the country’s currency. Under global finance, companies can meet their financial requirements easily. Global banking sector could facilitate e-banking and e-business. This would integrate countries economy globally and its prosperity would be enhanced. DEMERITS OF GLOBALISATION: Globalization is never accepted as unmixed blenings. Cities have pessimistic views about its ill-consequences. When a country is opened up and its market economy and financial sectors are well iberalized, its domestic economy may suffer owing to foreign economic invasion. A developing economy when lacks sufficient maturity, globalization may have adverse effect on its growth. Globalization may kill domestic industries when they fail to improve and compete foreign well-managed, well-established firms. Globalization may result into economic imperialism. Unguarded openness may become a playground for speculators. Currency speculation and speculators att acks, as happened in case of Indonesia, Malaysia Thailand, Philippines etc recently may led to economic crisis. It may lead to unemployment, poverty and growing economic inequalities. Despite its some shortcomings, benefits of globalization are likely to outweigh their drawbacks. Globalization essentially provides greater opportunities for the faster growth and economic development of the country and improve economic welfare. It provides wider and large-scale economic activities and employment opportunities. In a planned economy such as India, an indicative planning of desirable globalization process can be great use. India’s perspective planning for foreign investments and entry of MNC’s should be positive towards modernization of India. Besides, Research and Development (R&D) as well as technological up gradobious should be an integral part of India’s liberalized planning towards market economy. In short, globalization implies undeterred business activities and interaction among the firms and people with a global approach. It needs change in the outlook. It requires relaxing of control and regulations. It is heartening to note that an awareness of the government in India is on this line. Relief to foreign investors, new industrial policy, new trade policy, new fiscal policy, banking reforms, FERA and MRTP relaxation, acceptance of WTO agreements etc all suggest a positive out look of Indian policy-makers towards globalization. Indian government has assumed the role of promoter, care taker and regulator of market economy in the country in a desirable manner. Journey has begun. Destination is yet far. Perspective Although the social science literature on globalization has proliferated, social policy and social work scholars have not adequately debated the consequences of globalization for social welfare and social justice. Drawing on different social science interpretations of globalization, four major perspectives that offer different analytical and normative insights into globalization are identified and their implications for social welfare and social justice are briefly examined. The implications of these perspectives for social policy and social work scholarship are also considered. The concept of globalization is widely used today not only in the social sciences but in journalism and popular discourse. However, it is still poorly defined. Although loosely employed to connote the processes of social change that are affecting social relations between people living in the world's different nation states, the nature of these processes and their effects are widely debated and contested in the social sciences today. Nevertheless, these processes are said to be qualitatively different from earlier forms of international exchange in that they are more complex, intense and volatile. They are also believed to be fostering a historically unique interdependence between the people and nations of the world that will ultimately result in the integration of economies and societies. Of course, this interpretation has been disputed and an alternative view that defines globalization as no more than the acceleration of historic patterns of international exchange has also been formulated. Different interpretations of the nature of global change reflect different disciplinary social science perspectives. While economists view globalization as the creation of a world economic market, sociologists place more emphasis on the role of international social relations, communications and population movements in fostering space-time compression, post-modernity and cultural diffusion. In turn, political scientists stress the way power relations operate internationally to foster new systems of global regulation and governance. These diverse disciplinary perspectives have different normative implications that not only evaluate globalization differently but inspire different policy perspectives on how the process of globalization might and should be molded. These normative dimensions are of obvious interest to scholars in the fields of social policy and social work. However, as will be shown, different social science interpretations reach very different conclusions about globalization's consequences for welfare and justice. This article outlines four major perspectives which offer different analytical and normative insights into this issue and then considers the social welfare and social justice implications of these different perspectives. But first, it provides a brief discussion of the emergence of the concept of globalization and its social science usage.

Fizzy Sparkling Lemonade Made With Science

Fizzy Sparkling Lemonade Made With Science Relax and enjoy a refreshing glass of lemonade while doing science! Heres an easy way to turn ordinary lemonade into fizzy sparkling lemonade. The project works on the same principle as the classic baking soda and vinegar volcano. When you combine an acid and baking soda, you get carbon dioxide gas, which is released as bubbles. The acid in the volcano is acetic acid from vinegar. In fizzy lemonade, the acid is citric acid from lemon juice. Carbon dioxide bubbles are what gives soft drinks their fizz. In this easy chemistry project, youre simply making the bubbles yourself. Fizzy Lemonade Ingredients You could do this project with any lemonade, but if you make your own it wont end up insanely sweet. Its up to you. For the lemonade base you need: 2 cups water1/2 cup lemon juice (contains citric acid and a smaller amount of ascorbic acid)1/4 cup sugar (sucrose) Youll also need: sugar cubesbaking soda (sodium bicarbonate) Optional: toothpicksfood coloring Make Homemade Fizzy Lemonade Mix together the water, lemon juice, and sugar. This is tart lemonade, but youll sweeten it in a bit. If you like, you can refrigerate the lemonade so you wont need to add ice to chill it later.For kids (or if youre a kid at heart), draw faces or designs on sugar cubes using toothpicks dipped in food coloring.Coat the sugar cubes with baking soda. You can roll them in the powder or shake sugar cubes in a small plastic bag containing baking soda.Pour some of your lemonade into a glass. When youre ready for the fizz, drop a sugar cube into the glass. If you used food coloring on the sugar cubes, you can watch the lemonade change color.Enjoy the lemonade! Expert Tip Another option, besides food coloring, is to paint the sugar cubes with an edible pH indicator. The indicator will change color according to whether its on the powdered sugar cube or in the lemonade. Red cabbage juice is a good choice, but there are other options you can find in your kitchen.Any acidic liquid will work for this project. It doesnt have to be lemonade! You could carbonate orange juice, limeade, grapefruit juice, or even ketchup (maybe not so tasty, but it makes a nice volcano). Got another lemon? Use it to make a homemade battery.

Existentialism Therapy

Existentialism Therapy Free Online Research Papers Existential therapy is aimed at dealing with people and their existence and letting them have the freedom to make choices in shaping their life. This type of therapy tries to help the client improve their self-knowledge and then helps them to make their own decisions about life (Szasz, 2005). The therapist makes the client aware that they are responsible for their own life. Existential therapist are also more focused on the present and the future and do not focus as much on the past. Although they may talk about the past, it is more as a reference to help the client learn from the past so that they can improve their present. There are six main concepts that existential therapy try to address with clients: self-awareness, freedom and responsibility, identity and relationships, anxiety, feeling of meaninglessness, and death (Szasz, 2005). When the client learns to increase their self-awareness they learn that they chose their actions so they can basically create their own destinies. Also they become aware that they have the potential to act or not to act, it is a decision that they have to make. Some of the awareness that the therapist helps the client realize is that they are not living in the present because they are preoccupied with the past (Corey, 2005). Which in return they come to the conclusion that they are not condemned to a future similar to the past. They have to use the past and learn from it and that is the awareness that the therapist tries to show their client. The next concept to be talked about is freedom and responsibility of the client. In existential therapy the client has full freedom to do what they may, but they also learn to take the responsibility for their actions. Clients who refuse to accept responsibility by blaming others for their problems will not profit from therapy (Szasz, 2005). The client has to learn that they shape their own lives and they are the ones making decisions for them and therefore they are responsible for what happens. The therapist is there to talk to the client about how others may influence the client’s decisions and encourage them to move towards make their own choices (Corey, 2005). Everyone is trying to make their own identity and be someone who is unique. People also make relationships because we are naturally driven to connect with others, but we must open up to others and also care for them too or else the relationship will not last (Corey, 2005). This is where existentialist talk about loneliness because clients may see themselves as failures if they cannot develop relationships. The trouble with relying too much on relationships is that people may learn to trust their directions, values, or beliefs instead of trusting in themselves to find their own answers or values (Corey, 2005). Existential therapy can really help clients challenge the meaning of their lives. Meaninglessness in life leads to emptiness and hollowness, or a condition that Frankl calls the existential vacuum (Corey, 2005). When dealing with a client and trying to help them with having feelings of meaninglessness, the therapist’s trust is important in teaching clients to trust their own capacity to discover a new source of values. The client may experience some major anxiety when dealing with getting rid of or altering old values. This anxiety may even get worse if they do not find appropriate ones to replace them with (Corey, 2005). Anxiety is one of the major concepts that existential therapist’s deal with. Anxiety arises from personal strivings to survive and to maintain and assert one’s being. The feelings anxiety generates are an inevitable aspect of the human condition. Existential therapists differentiate between normal and neurotic anxiety. Normal anxiety is an appropriate response to an event being faced. Existential anxiety is a constructive form of normal anxiety and can be a stimulus for growth (Corey, 2005) . Existentialist’s do not view death negatively and think that awareness of death as a basic human condition gives significance to living. Frankl believes that death should not be considered a threat; rather death provides the motivation for us to live our lives fully and take advantage of each opportunity to do something meaningful (Corey, 2005). When people are too afraid of death it begins to run their life and they may not do something they want to because they are scared of what might happen. With existential therapy they talk to the clients and let them know that death is not something they should be scared of and it should not run their lives. Two important foundational theorists in existentialism were Viktor Fankl and Rollo May. Viktor Frankl called his form of existential therapy logotherapy, which is derived in part from the Greek word logos, which can mean to study word, spirit, God, or meaning. It is this last sense Frankl seems to focuse on the most, with his logotherapy Frankl postulates a will to meaning as the key motivation of the human being. Frankl also uses the Greek word noà ¶s, which means mind or spirit. In traditional psychology, he suggests, we focus on â€Å"psychodynamics,† which sees people as trying to reduce psychological tension. Instead, or in addition, Frankl says we should pay attention to noà ¶dynamics, wherein tension is necessary for health, at least when it comes to meaning. People desire the tension involved in striving for some worthy goal, making the bumps in the road of life worth it for the journey. (Boeree, 2006) The other important theorist, Rollo May, is for he uses some traditional existential terms slightly differently than others, and invents new words for some of existentialism’s old ideas. Destiny, for example, is roughly the same as thrown-ness combined with fallen-ness. (Boeree, 2006) It is that part of our lives that is determined for us, our raw materials, if you like, for the project of creating our lives. Another example is the word courage, which he uses more often than the traditional term authenticity to mean facing one’s anxiety and rising above it. May is also the only existential psychologist who discusses a type of staging of development. Starting with Innocence, going through rebellion, ordinary, and ending with creative. These are not stages like those of Freud or Erikson. They are different in the sense that at any given developmental stage a person may experience any of these. A child can be at the innocent, ordinary or creative stage at any given time. Existentialism deals with people and existence. The therapy is aimed at helping a client improve and enhance their hold on choice making, freedom, and their self-knowledge. Making them responsible and capable in their own lives.

Broken Family

A vast majority of my friends, peers, and coworkers have a relationship with at least one parent. It has really caused me to question a lot about my faith, myself, and the fairness of not being able to choose one’s parents. The idea of a parent is a tough one. What does it take to make a parent? What is a good parent and what is a bad parent? Absentee parents fall somewhere in between because even if they live at the same address as their children, they’re emotionally unavailable. According to dictionary. com,  the definition for parent  is: a mother or a father. I’m no expert on the etymology of words, but I think we should redefine parents a bit. A parent is someone who loves, nurtures, and cares for their young. There are plenty of â€Å"parents† in the world who may not have bore children of their body but have certainly bore children of their heart. As a young Christian, I have been tormented by my relationship with my mother and my other family members. Over the years, my relationship with her and my siblings has deteriorated tremendously. On the one hand, Christians are told to be loving. We are to endure with one another and bare with one another. This is noble philosophy and life doctrine but implementation of it is excruciating. How do we know when to â€Å"endure with one and bare with one another† and when to draw the line to protect ourselves from mistreatment? I have grappled with this concept for years. When I have asked my friends their opinion, most of them shrug their shoulders and insist that I have to accept my family how they are. Obviously, these are individuals with relatively functional families. They have no idea what I’m subjecting myself by toughing it out and â€Å"dealing† with some of my relatives. Only until recently has God really started drawing my attention or I’ve been more attentive, to what His word says about parents and baring with them. A few days ago, I read 1 Kings 19: 20-21. It says: â€Å"Elisha then left his oxen and ran after Elijah. Let me kiss my father and mother good-by,† he said, â€Å"and then I will come with you. † â€Å"Go back,† Elijah replied. â€Å"What have I done to you? â€Å"†¦. Then he set out to follow Elijah and became his attendant. † In this verse, Elisha does not go back to his parents. Instead, he leaves his farming equipment and speeds to follow Elijah. In Hebrews 11:24, the Bible says â€Å"By faith Moses, when he had grown up, refused to be known as the son of Pharaoh’s daughter. † In reality, Moses was the adopted son of Pharaoh’s daughter but here’s where the debate on parents comes in. Pharaoh’s daughter had parented Moses as if he were her own son. But Moses refused this tie to the Pharaoh’s daughter. Similarly, Christians are free to cast down false relationship or ties to people by faith. Being cared for as a child is important but it should not be the sole reason why we keep contact with or relate to people that did so. Parenting is so much more that providing for a child. It is having a relationship with a child. I am sure that there are many people who have family problems. Not everyone needs to disown their parents and siblings to deal with it but sometimes it is necessary and even ordained by God. In Genesis 12:1, the Bible says: â€Å"The Lord had said to Abram, â€Å"Leave your country, your people and your fathers’ household and go to the land I will show you. † The very first book in the Bible contains a story where God ordains a mighty man to leave his father’s household. We are not meant to stay with our parents forever. There are plenty of stories throughout the Bible of people being at odds with family members. The story of Joseph is a prime example of sibling rivalry and dissension that leads to Joseph being betrayed and sold into slavery. His brothers were his blood kin but they did not have his best interest at heart. Maybe one way to analyze the story of Joseph is to say that God recognized the jealousy in the brothers of Joseph. Hence, he decided that it was even better for him to be sold into slavery than to live around a den of jealousy amongst â€Å"family ties†. Mothers, you can’t live with ’em and you can’t live without ’em. But God says that He will not leave us even when our mothers do. In my post:  Ã¢â‚¬Å"In my Darkest Hours†¦ â€Å", I discuss the tension that can exist between family in greater depth. That post also talks about God’s response as a loving Father and how He intervenes in these circumstances. How do you define a parent? Have you ever had a really tumultuous relationship with a parent that you couldn’t over come? If you did overcome it, how so? Do you think that God may be calling you to something greater that will draw you away from conventional family ties? When do you bare with a parent, and when is it time to walk away from emotionally abusive relationships? 1. Isang pamilyang di magkasundo o/at magkahiwalay or divorced. 2.

S Center for Marria ge and Family released a study in November 2005 that shows broken family structures consistently lead to education difficulties for children. When it comes to educational achievement,† the study says, â€Å"children living with their own married parents do significantly better than other children. † The report found that children from non-intact families (children living in a situation other than with their own married father and mother) have significantly higher rates of difficulty with all levels of education, from pre-kindergarten through to primary, secondary, and college-age levels. Each year a child spends with a single mother or stepparent â€Å"reduces that child’s overall educational attainment by approximately one-half year† suggests the report. The study, a comprehensive review of recent academic research on the relationship between family structures and children’s academic performance, compared education outcomes from children growing up with their own married parents to children in non-intact family structures such as divorced, single, remarried or cohabiting parents. Family structure was consistently found to be the deciding factor in a wide range of child behaviors that directly influence academic performance, including emotional and psychological distress, attention disorders, social misbehavior, substance abuse, sexual activity and teen pregnancy. Children from non-intact homes had higher rates of stress, depression, anxiety and low self-esteem, particularly as teenagers. The study found that preschool children from broken homes were three times more likely to suffer from attention deficit disorders than children from intact homes. Children from single-parent homes suffered from more physical health problems, as well. Pre-school children from single-parent homes were also less likely to be read to or given help with letter-recognition. A During elementary school, children from non-intact families scored consistently lower on reading comprehension and math, and had more difficulty maintaining their grade levels overall. Children from married parents had much lower rates of behavioral problems in the classroom than children who did not live with married parents. In particular, boys from broken marriages showed a higher rate of classroom misbehavior. For teenagers, students from broken homes were 30 percent more likely to miss school, be late, or cut class than students from intact homes, in part because single parents had more difficulty monitoring their children. These children were also at higher risk for smoking, using drugs and consuming alcohol. Teenagers from non-intact families were more likely to be sexually active and had higher rates of pregnancy. Girls from divorced single-mother homes were at greatest risk for teenage pregnancy. The study also found that children who were in a single-parent or step-parent home by the time they were ten were more than twice as likely to be arrested by age 14. A Children who never lived with their own father had the highest likelihood of being arrested. The study reports that a majority of U. S. children will have spent a significant part of their childhood in a one-parent home by the time they reach 18. Single parent homes in the U. S. nearly doubled in the period from 1968-2003.

Theory of Extreme Capital Structure Essay Example | Topics and Well Written Essays - 1500 words

Theory of Extreme Capital Structure - Essay Example Therefore, capital structure can be defined as the arrangement of capital. In order to analyse capital structure, we need to highlight the difference between capital structure and financial structure. The terms are interchanged in some circles to mean the same, but they are not quite the same. Financial structure is the sum of all the means the firm uses to fund its activities. Therefore, financial structure comprises of net worth and liabilities of the company i.e. short and long term. The capital structure on the other hand is financial structure excluding short term borrowing. Capital structure has already been seen as two-fold, with the finance and asset structure. The source of capital is what determines what asset will be purchased. The structure of capital is categorised as follows: 1. According to sources: The structure may either be simple or complex. A simple structure consists of a single source while the complex is where the sources are more than one. (Although retained e arnings is not considered an additional source). This mode is only possible under the fund concept because it is rare for a firm to have one asset, invalidating the asset concept. 2. According to sources This is broadly categorised into internal and external sources. Internal sources comprise of share capital (bonus issue), capital reserve, and reserve and surplus. On the hand the external sources include share capital (bonus issue excluded), share premium, forfeited shares, long term and short-term liabilities and debentures. 3. According to ownership This is either ownership capital or creditorship (debt) capital. Ownership capital includes equity share capital and retained earnings while creditorship comprises of debentures, long-term and short-term liabilities. It is agreed by all accountants where preference shares should be grouped as they have the both elements of ownership and debt. 4. According to cost behaviour This classifies the assets as either fixed cost or variable co st, depending on their expense implications. The fixed cost capital include preference share, long term debt and debentures whereas variable cost capital include equity share and short term liabilities. Firms have different capital structures depending on industry, company type, and proportion of capital contribution. The theories of capital structure try to ask the pertinent questions in leveraging, valuation, and financial balance. This involves evaluating how a firm can affect its total valuation factoring debt and equity, how debt affects the firm’s position. This is by use of accounting ratios 1  Where  is the firm’s debt yield, assuming the element of perpetuity of debt 2.  [E=EBIT-I] Where we assume 100% dividend payout and the firms earning are constant with no element of growth. Therefore, the earnings/price ratio gives the market discount rate, which equals the present value of the series of expected future dividends at the existing market value of the share. 3.  Where  is the firm’s overall capitalisation rate. It computation is normally the weighting of the cost of capital as shown below + The theories of capital structure try to explain the relationship between capital, leverage and the firm’s value. What we want to know is what happens to , and when the degree of leverage (D/V) increases or how is the value of capital

Engineering Management - Assignment EM1 Research Paper

Engineering Management - Assignment EM1 - Research Paper Example A low ratio in comparison with industry averages indicates an inefficient use of business assets. The Return on Assets Ratio is calculated as follows: Return on Assets = Net Profit Before tax / Total Assets = 1M / (1.2M + 0.7M -0.5M) = 1M / 1.4M = 0.714 Return on Investment (ROI) Ratio Return on Investment Ratio is the ratio of percentage of return on funds invested by the owners. The ROI is perhaps the most important ratio of all. The ROI should be high enough for an investor to invest in risk taking business proposition. The ROI is calculated as follows: Return on Investment = Net Profit before Tax / Net worth. (Word Count = 497) 1. (b) Do you think the above structure is satisfactory How would you change the structure and why would you change it To find answer to the above question first we have to look at what is an Organisation Structure I will just quote one, which I feel gives the essence of organization structure. 'The structure of an organization [is] the sum total of the ways in which it divides its labor into distinct tasks and then achieves co-ordination among them' (Mintzberg, 1989).' In analyzing the organization structure of Tees Valley Doors (TVD), I find that the organization structure is lacking some vital points. 1. This is a top-heavy organization structure. The total no. of employees are 70. For which there are 3 whole time Directors, 6 managers. 2. The allocation of jobs to the Directors are also not proper e.g. the Distribution Manger is having 4 assistants under him and the Warehouse manager is having 5 operators under him. I feel the posts of Managers here are superficial. It should be the job...It is calculated before income tax because tax rates and tax liabilities vary from company to company for a wide variety of reasons, making comparisons after taxes much more difficult. The Net Profit Margin Ratio is calculated as follows: This ratio reveals how well inventory is being managed. It is important because the more times inventory can be turned in a given operating cycle, the greater the profit. It is stated that inventory turn over is three times a year. This measures how efficiently profits are being generated from the assets employed in the business when compared with the ratios of firms in a similar business. A low ratio in comparison with industry averages indicates an inefficient use of business assets. The Return on Assets Ratio is calculated as follows: Return on Investment Ratio is the ratio of percentage of return on funds invested by the owners. The ROI is perhaps the most important ratio of all. The ROI should be high enough for an investor to invest in risk taking business proposition. The ROI is calculated as follows: 2. The allocation of jobs to the Directors are also not proper e.g. the Distribution Manger is having 4 assistants under him and the Warehouse manager is having 5 operators under him. I feel the posts of Managers here are superficial. It should be the job of supervisors to handle operators and assistants.

NKT cells Research Paper Example | Topics and Well Written Essays - 1000 words

NKT cells - Research Paper Example Immunologists have been striving to unearth the connection between NKT cells and the inflammatory characteristics of asthma, in a bid to design new intervention strategies. This paper will review the biology of Natural Killer T cells and the prevention strategies of asthma and allergic diseases. Biology of NKT Cells Natural Killer T cells form a subset of lymphocytes as scientists have described. Depending on the T-cell receptor repertoires, NKT cells fall into three categories. The first type of NKT cells is the classical NKT cells that exhibit conserved T-cell receptors (Akbariet al 2006). Immunologists have been described type 1 NKT cells in mice and humans, with those in humans named invariant NKT cells. Type 2 is also available in both mice and humans but have a diverse range of T-cell receptors. However, type 2 faces a restriction from CD1d. The third type forms the independent category of NKT cells characterized as expressing either Ly49 or NK1.1 (CD161 in humans). Moreover, i t proved quite difficult to isolate this type of NKT cells. Immunologists have succeeded in isolating type 1 and associating it with the development of asthma. NKT cells present numerous similarities to Th2 Cells, which trigger the processes that cause the development of asthma. ... However, the two types of cells exhibit different activation processes (Wohlleben&Erb, 2006). Processes Leading to the Development of Asthma and related Atopic Diseases Experts seeking to understand the immunologic processes that lead to the development of asthma, have described the process in detail. Asthma results from the Th2 responses taking place in the lungs. The production of Th2 responses result from the action of allergen specific CD4+. The basis of asthma development is that there must be activation of transcription factors from the downstream factors resulting to the production of Th2 effector cells. The effect of these processes is the production of cytokines such as interleukins IL-4, IL-5, IL-9, and IL-13. Moreover, these processes trigger the recruitment of eosinophils and allergen specific immunoglobulin E by beta cells (Mallevaey et al, 2006). Granulation of eosinophils and mast cells occurs with as they indulge in a cross-linking with immunoglobulin E (igE). This ca uses the production of mucous and airway hyper-reactivity and a chronic inflammation of the airway. These are the central attributes of asthma.Processes that trigger Th2 responses often lead to airway hyper-reactivity and inflammation. Immunologists have highlighted that Th1 responses do not trigger this hyper-reactivity and inflammation defining asthma and other atopic diseases. There is evidence suggesting that children contacting bacterial infections that trigger Th1 responses in their earlier years have a less likelihood of developing asthma. NKT Cells and Asthma There is evidence that NKT cells have the potential to trigger Th2 responses that often lead to development of asthma and other atopic diseases. This is because of their ability to recognize glycolipid

The conservation management of Coquerel's sifaka (Propithecus Essay

The conservation management of Coquerel's sifaka (Propithecus coquereli) in Madagascar. Is conservation action carried out for Coquerel's sifaka successful - Essay Example This has been attributed to depreciation in its natural habitat due to invasion of man in the forests. Fires caused by nature and man are a menace to the animal since it derives its upkeep from the very vegetation and forest that is destroyed in the process. Hunting is another threat that is posed to the species as the human populations continue to rise. The government in the island has several Nature Reserves and special reserves in place so as to conserve the most endangered ecological habitats. The two significant National Parks where these primates can be found are the Ankarafantsika National Park and the Bora Special Reserve (Wallis, 1997). Communities have also been involved in the task of trying to protect the lemurs. They have been educated on the special needs and behaviors of Coquerels Sifaka and how to coexist peacefully with them. There are various proposals by the Malagasy government that are aimed at putting structures in place to help identify the most viable and practical ways of conservation. This has led to the establishment of data pools containing information on various species, their habitats, and behaviors. In addition, the public is made aware of various development strategies instigated for those animals that may be caught. Key collaborations have been instrumental in ensuring that conservation efforts are sustained on a long term basis. This was evident in the1986 Government Conference that focused on the conservation of the diverse ecosystems present in Madagascar by devising new and effective management systems. In addition, there was a project plan in 1986 to investigate the protected areas, and come up with ways of better enhancing their rich biodiversity (Richard, 1978). The Coquerels Sifaka can be said to survive longer with the passing of generations if the above efforts continue. However, it has been reported that hunting has been in the extreme in Ankarafantsika for this

The government in the island has several Nature Reserves and special reserves in place so as to conserve the most endangered ecological habitats. The two significant National Parks where these primates can be found are the Ankarafantsika National Park and the Bora Special Reserve (Wallis, 1997). Communities have also been involved in the task of trying to protect the lemurs. They have been educated on the special needs and behaviors of Coquerels Sifaka and how to coexist peacefully with them. There are various proposals by the Malagasy government that are aimed at putting structures in place to help identify the most viable and practical ways of conservation. This has led to the establishment of data pools containing information on various species, their habitats, and behaviors. In addition, the public is made aware of various development strategies instigated for those animals that may be caught. Key collaborations have been instrumental in ensuring that conservation efforts are sustained on a long term basis. This was evident in the1986 Government Conference that focused on the conservation of the diverse ecosystems present in Madagascar by devising new and effective management systems. In addition, there was a project plan in 1986 to investigate the protected areas, and come up with ways of better enhancing their rich biodiversity (Richard, 1978). The Coquerels Sifaka can be said to survive longer with the passing of generations if the above efforts continue. However, it has been reported that hunting has been in the extreme in Ankarafantsika for this

Creating a Travel Planning ICT System Essay Example for Free

Creating a Travel Planning ICT System Essay In this project I will be creating a system to help plan the costs, amount of people and which people are going on the overnight trip. Here you will be taking the role of Sana, who is helping her French teacher (Mr Campbell) work out the costs of the week long French trip as he was experiencing some difficulty. On a day to day basis Mr Campbell has to create a letter about parent evenings for the trip, permission slips, dietary and medical requirements and remaining money. He also needs to work out the total in goings and total outgoings and make sure that the school doesnt make a loss but doesnt need to make a profit. He will also need to create a record of data about which pupils are going and arent going and how we will put this in and use this to help create letters As Mr Campbell was experiencing some difficulty working out the costs using a calculator and paper and you had suggested that you would create a system that helps him work out the cost very easily and is a very user friendly design (maybe a user guide to help those who find this system hard and need some help) and you should ensure that anybody with little knowledge of computers is able to change certain amounts e.g. amount of people to see how this affects the overall costs. Sana has also offered to create a system in which Mr Campbell can enter a pupils data, how much they have paid (deposit and other monies) and if he/her has brought in the reply slip, this system must also be able search within this data and pick out what you are asking to see. As well as creating a system that does this you must create a system that links to the list of names and using the information that you have searched for I should be able to create a letter to be sent to parents about reply slips, remainin g money etc. My user for this system is Mr Campbell and Mrs Mccloud and could be the deputy head, head teacher etc. As anyone who needs to know how many people will be missing school and how long for, other teachers will need this information to ensure that all important work is given before and after (this information could be presented in queries or reports). Many people will need to access this record or receive information about the trip so I should be able to send out pieces to teachers e.g. form, lesson etc about which dates will be missed. At the moment the business is run by Mr Campbell and he runs it by collecting information from letters and from pupils then writing it down into a log book but this way is too long and too hard so I will be creating a system which will significantly decrease the amount of time wasted by sifting through handwritten data. Sub problems involved In this task there are 4 different sub-problems within the system they are shown on the next page in the diagram with the problem being at the top and the sub problems being shown below and also how these sub problems are linked shown on the diagram. My first sub problem is my costing sheet which will work out all the separate and total costs of the trip. For this sub problem I could use Microsoft word and Microsoft excel. There are advantages and disadvantages of all of these problems and there are all listed below these will all help me to decide which would be the best method of working out these costs. I have chosen these two programs because in each one I can create tables. Different methods of tackling the problem In Microsoft word I can * Create a table * Merge cells * Change the page layout (portrait and landscape) * Change the background colour of the cells * Change the text colour of the cells * Change the justification of the cells * Make cells bold, italic or underlined * Auto fit the cells * I can sort the data * I can add formulas * Use a table auto format But using Microsoft word also has its disadvantages * Harder to change formulas * Harder to use * If something needed to be changed if would be harder for the user I think that Microsoft word isnt a very good program to use because even though you can do a lot of things with making the table and changing things within the table I dont feel that this is the right program to use as I would like a program specifically designed to do things like costing sheets as I have more experience with those so I am able to make them more user friendly and use more features on it. In Microsoft excel I can * Create a table * Merge cells * Change the page layout (portrait and landscape) * Change the background colour of the cells * Change the text colour of the cells * Change the justification of the cells * Make cells bold, italic or underlined * Auto fit the cells * I can sort the data * I can add formulas * Use a table auto format * Create graphs with data * Do auto sum * Use conditional formatting I can also do many other things that would be useful to the sub problem. The disadvantages of this is * it might seem hard to use the only problem I have with this program is that it could look hard top use but with a user guide and a colour coded system I think that that is over come easily and because I am able to do many different things with this package as I am more familiar to it and I think that that would benefit the user. Any methods of doing this would be better than handwriting it because then I would have to work everything out for each little change and keep writing out the results and this can be very time consuming so the best option is to use a computer with maybe a program that is able to create costing sheets For my second sub problem I am creating a poster to advertise this trip to France I am going to use Microsoft word, publisher or paint. I will be listing there advantages and disadvantages to help me to decide which one is more appropriate and suited to this task. Microsoft word is good because * can insert picture * can insert text * can make text boxes * can change colour, background and type and size and justification of text * can change colours etc of background * can insert tables to display data * can insert diagrams You can also do many other things with Microsoft word sop it would be a good program to use but I dont have as much freedom with the text etc then what I would have with another program in which I am able to do many more things. Paint is a good program to use because * I have a lot of freedom within this program * Can create my own lines and shapes and copy and paste parts easily * Can insert text boxes Microsoft paint also has many other good points but I still think I that this program isnt the most ideal because: * I dont now how to make it fit the whole page * Cant use word art, would have to copy and paste it There are also more problems with it and they wouldnt really influence my decision as I think that using paint is already to tedious from the above two problems so it isnt the most desirable solution. Microsoft publisher is good because * I have freedom * can insert picture * can insert text * can make text boxes * can change colour, background and type and size and justification of text * can change colours etc of background * can insert tables to display data * can insert diagrams I can also do other things with Microsoft publisher but they do not need to be stated as I dont feel that that has any tedious or major problems with it so feel that for this task it is the best piece of software to use. Using a computer and its software to tackle this sub problem rather than using a computer because it would take me a long time as well as designing it I would them need to draw and stick anything on then I would need to colour each drawing in staying within the lines and making sure the colour is even this isnt a very good thing because it would take vary long time and wouldnt look professional so for this task it is better to use a computer. For my third sub problem I am creating a record to store all the details about pupils and teachers going on this trip I will be using either of these two programs as I can use tables in both Mycroft access and Microsoft word. Microsoft word would be good to use because * I can make a table * I can sort the data * I can give the data titles The rest of what I can do with Microsoft word is irrelevant and there are too many problems to list with it because I count do much with this program and there is no use in listing it but I know for definable that I will not need to used this program as I cant even make forms or use queries. Microsoft access would be good to use because * I can create queries * Create forms * Search for and sort data * Create definite field headings for the record * Be able to mail merge this data There are also many other good points but I do not need to state them because of what is above and concerning this sub problem there arent any bad points of using this piece of software for this sub problem. Using a computer is much better than using a hand made system because in a hand made system you would have to write each one out and if any changes needed to be made I would have to re-write the whole sheet and finding data and taking parts of that data would also be very hard as I wouldnt be able to do it in a short period of time so using a computer would save time and frustration. For my fourth sub problem I am creating a letter which will need to be mail merged so I can do this quickly and efficiently. I can use two programs for this task Microsoft word pad and Microsoft word. They bother have there advantages and disadvantages and stating them will help me to decide which program is better. But I already know as I cannot mail merge in word pad and retyping this letter would take too long so I already know that Microsoft word is the best option as I can mail merge here. Using computer I much better than writing this letter out again and again or writing it out and leaving gaps for details because it is less time consuming if I do it this way sop using a computer is the much better option. Reusability Each of my sub problems can be used again. The first sub problem (costing sheet) is reusable because it is not just for one year because it can be used for later French trips or even other overnight trips because if anything needs to be changed like a cost for any one thing you can without changing any of the formulas as this costing sheet will be totally user friendly. The second sub problem (poster) will also be reusable because if you just change maybe the title and dates you will have a poster for another overnight trip or a poster for the same trip for a different year. The third sub problem (record) will also be reusable because if you were to delete the fields you would be able to reuse the system for a new year. The last sub problem (letter) will be reusable because if you were to use the record system to do this you would just need to delete previous records and put the new ones in and use it for next years and the years after trip. Testing For sub problem 1 (costing sheet) testing is needed. For sub problem 3 (record) testing is needed. For sub problem 4 (letter) testing is needed.

Assignment On Aircraft Power Systems

Assignment On Aircraft Power Systems In this assignment, I intend to provide a brief presentation about the principle of operation of the aircraft electrical power systems, specifically, Integrated Drive Generators (IDG) in a modern aircraft. I will compare and contrast the fluid and electrical methods of power generation and give a brief on the safety precautions to be followed when handling aircraft electrical power supplies and during a functional test. There are various kinds of power generation on an aircraft, namely electrical (generators batteries), fluid (hydraulics pneumatics). Depending upon the application, the power sources may vary. AIRCRAFT ELECTRICAL SYSTEM The main function of any aircraft electrical system is to generate, regulate and distribute the electrical power in the aircraft. Modern aircrafts use more electrical power as they are equipped with more Electronic Flight Instrument System (EFIS). This is done so as to reduce pollution in the environment, for a clean and safe flight. Electrical power is used to operate: Aircraft Flight Instrument- Electronic Centralized Aircraft Monitoring (ECAM) Essential Systems- Primary Flight Display (PFD), Navigation Display (ND) Passenger Services- In-Flight Entertainment (IFE) Most of the aircraft systems use a power standard of 115 [emailprotected] 400Hz; 28VDC. There are various electrical power sources on the aircraft: Engine Driven AC Generators (EDG) Auxiliary Power Units (APU) Ram Air Turbine (RAT) Battery Supply External/Ground Supply (Spoor, 2012) Components in an electrical system include: AC Generator/Alternator produces AC power. Constant Speed Drive Unit (CSDU) regulates the rotating speed (input) to deliver a constant output from the engine to the generator. Integrated Drive Generator (IDG), Generator and CSDU connected either coaxially or side-by-side. Mostly coaxial connection. Transformer Rectifier Unit (TRU) converts the AC power to DC power Generator Control Unit (GCU) monitors and controls the generator output. Each engine powers up one or more generators. Airbus A380 has four engines and four generators. Whereas, Boeing 777 has two engines and two generators. The power produced by these generators is used to power up the entire aircraft. (Boeing, 2012) All the other power sources, except external supply, are used in case of emergencies only. External power supply is used on ground when the engines and the APU are not running. It is supplied via Ground Power Unit (GPU). GPU can be portable or stationary and they provide AC power through the external plug on the nose of the aircraft. They can be used to power up an entire aircraft or a specific area in the aircraft. (Spoor, 2012) Figure : Aircraft Electrical System (Classic Jet Sims, 2012) AIRCRAFT HYDRAULIC SYSTEM The principle of a hydraulic system is to convert fluid power into mechanical power and then use it for various applications on the aircraft, such as extension/retraction of landing gears, flaps, and speed and wheel brakes. The power source here is the hydraulic fluid. The pressure for generating the hydraulic power is supplied by the Engine Driven Pump (EDP) and the Electric Motor Driven Pump (EMDP). They are both mounted on the engines. Commonly used hydraulic fluids on the aircraft are: MIL-H-5606 (Mineral Based Fluid) MIL-H-83282 (Synthetic Hydrocarbon Based Fluid) MIL-H-87257 (Same as MIL-H-83282, but it has been improved in its low temperature viscosity) MIL-H-8446 (Phosphate-Ester Based Fluid) (Wikipedia, 2012) Special care must be taken when handling the hydraulic fluid. Some of the hydraulic fluids are skin/eye irritant. Also it is extremely important for the fluid to be free from any contamination for flight safety. Advantages of the hydraulic system as a power source includes: Lightweight Easy installation Simplified Inspection Minimum Maintenance Approximately 100% system efficiency, with only negligible loss due to friction. (EAC, 2012) Figure : Basic Hydraulic System (Free Online Private Pilot Ground School, 2006) COMPARISON OF AIRCRAFT ELECTRICAL AND HYDRAULIC SYSTEM FEATURE ELECTRONIC HYDRAULIC Construction Power is generated by the engine, by rotation of turbine shaft. Power is generated by incompressible hydraulic fluid. Pressure for hydraulic actuation is supplied by EMDP and EDP. Similar to that of an electric circuit. Components include: Generators/Alternators, Batteries, Switches, Bus bars, Fuses, Circuit Breakers, Voltage Regulators, Ammeters, and Wires. (Free Online Private Pilot Ground School, 2006) Components include: Reservoir, Pump, Hydraulic Fluid, Accumulators, Actuators, Filters, Hydraulic Fuses, Tubing, Pipes, Valves, and Seals. Uses Lights, Radio Equipment, Indicators, Warning Systems, Heaters, Starting motor. (FlightLearnings, 2012) Extension/retraction of landing gears, flaps, and speed and wheel brakes. Principle of Operation Generate, Regulate and Distribute electrical power generated. Work is done by moving an incompressible fluid, Pascals Law. (EAC, 2012) EMERGENCY DEPLOYMENTS IN EVENT OF GENERATOR(S) FAILURE In case of main engine driven generator (EDP) failure, there are various methods to ensure continued power supply for safe landing: Auxiliary Power Unit (APU) Ram Air Turbine (RAT) Battery When the main engine generators fail, APU or RAT is deployed. When the secondary methods fail, batteries are used as the last resort for a safe landing and evacuation. AUXILIARY POWER UNIT (APU) Auxiliary Power Units (APUs) is a small gas turbine engine which provides electrical, hydraulic and pneumatic power (depending on the design) for ground or in-flight operations. It is also used as a backup source in emergency situations. It is commonly found on large aircrafts. It is usually located in the tail end of the aircraft. When started, it normally runs on 100% speed. It produces 115VAC @ 400Hz. Some can also generate 28VDC. The main purpose of the APU is to start the engines in the aircraft. This is because the engine requires high rotational speed for its self-sustaining operation. In this case, APU is started by battery or hydraulic accumulator and then used to generate the necessary rotational speed. It is also used to run the equipment when the engines are shutdown. This is used for air conditioning for the passengers prior to engine start. However, it can also be connected to a hydraulic pump to power up hydraulic equipment (flaps and flight controls). (Wikipedia 2012) RAM AIR TURBINE (RAT) Ram Air Turbine is a small airflow driven turbine that is connected to either a hydraulic pump or an emergency alternator or a main generator. In normal flight, it is stowed away in closed compartment in wing or fuselage. It is deployed only when there is total power loss due to engine failures. It provides enough power to run the critical systems, such as, flight controls. The power generated by the RAT depends on the airspeed. More the speed, more the power generated will be. Some aircrafts use RAT in normal operation. For example, in crop dusting RAT is used to power up the chemical sprayer. (Wikipedia, 2012) BATTERY Aircraft batteries are used to start the engines or the APU. But they are also used in emergency situations as a last resort for safe landing. There have been cases where it has been used to restart the engines even after engine flame-out. They also act as a buffer for the DC connections. It regulates the voltage to ensure the power quality for the equipment connected to it. Two types of batteries are used in aircrafts today, Lead-acid and Nickel Cadmium (Ni-Cd). Lead-acid batteries are either valve regulated or vented. They are used in light and general aircrafts. Ni-Cd batteries are used in larger aircrafts. Lead-acid batteries are generally heavier and have less capacity than the Ni-Cd ones. (Dr. Thomas, 2010) Figure : Lead-Acid Battery (Chief Aircraft, 2012) Figure 4: Nickel-Cadmium Battery (Surplustraders.net, 2012) AIRCRAFT ELECTRICAL SYSTEM USING FREQUENCY WILD AC GENERATOR From 1950s to early 1960s some turboprop aircrafts used frequency wild, now Variable Frequency (VF) system. Airbus A380 and Boeing 787 Dreamliner are some of the modern civil aviation aircrafts that have adopted the VF system again. Figure : Simplified Frequency Wild System (Scribd, 2012) CONSTRUCTION As shown in Fig.4, the Variable Frequency Generator (VFG) is directly connected to the engine gear box. (Langlois, 2004) states: VFG is a conventional wound rotor synchronous alternator. There is no CSD or IDG in this system. This is done so as to improve the reliability of the system and also to reduce the weight of the aircraft. Airbus A380 uses aluminium cables instead of copper for weight reduction. The system is also fully computerized. Contactors and Breakers have been replaced by solid-state devices for increased reliability and performance (Global Aircraft, 2012). OPERATION Frequency Wild AC power can only be supplied to the resistive circuits such as the electrical heater, engine de-icing heaters, windshield heating, etc. as shown in Fig. 4. The AC power generated is sent to the TRU where the voltage is stepped down from 360Hz-760Hz (Langlois, 2004) to 28V and then rectified to DC voltage. Then it is used by the DC components. CONTROL PROTECTION A traditional Constant Frequency unit has only a constant frequency of 400Hz voltage supply. A constant speed drive unit drives the generator. It is also expensive and not easy to maintain. A VFG is flexible as it can handle a range of frequencies rather than a constant one. In this unit, there is no CSD or IDG. It is more advantageous over Constant Frequency Unit because: It has low maintenance Long lifespan Cheaper Process temperature is controlled within VFG itself. Equipment protection from excess torque damage The variable frequency generator (VFG) is used on applications with a high percentage of resistive AC or DC loads and provides power to many of the next generation aircraft. Hamilton Sundstrands variable frequency starter generator (VFSG) and motor controller system provides main engine start and control. The voltage is controlled around the generator. This is done by controlling field strength of the AC generator by feedback signal from the voltage regulator, which keeps the voltage constant irrespective of the speed and load variations. VFGs are preferred over DC systems because they were much less affected by poor brush performance at higher altitudes and they had better power to weight ratio. AC/DC ELECTRIC MOTORS AND ACTUATORS PERFORMANCE DC actuators are typically high-speed reversible series-wound motors. Their output is converted to driving torque using step-down gearbox. These motor actuators are self-contained units, as they combine both electrical and mechanical devices. They can exert linear thrust over a short distance. AC MOTOR DC MOTOR
