Physics Laboratory Checklist Essays - Laboratories, Microsoft Excel

Physics Laboratory Checklist - Mrs. Gordon International Academyrighttop Laboratory experiences are important parts of the International Academy's physics courses. Some of these experiences will be hands on labs using the materials in the physics lab kit and everyday household items, some will be virtual labs, using specially written labs intended to model as much as possible a real life experiment. In either case, you will be conducting the laboratory experiment following a set of instructions, collecting data, analyzing your results and reporting your conclusions. Sometimes just the amount of resources, materials, and data can get overwhelming. It is important in science to make conclusions based on the data so it is equally important for you to include your data when you report your results and conclusions. Often we are simply confirming a known physics concept, but in a lab (or home) environment we rarely see what we expect. There are many reasons for that, but most importantly is the idea of experimental uncertainty and error. We will study the effec ts of these throughout our courses. This checklist (found on last page) is meant to help organize your lab data and analysis so that you get the most from the experiment and of course the highest grade possible on your lab report. We do not use traditional lab reports but instead simply ask you to answer a few questions about your lab. Because each student will have their own data, each student's answers may be very different. That does not mean anyone is necessarily right or wrong, but it does mean that it is critically important that you include your data to support your answers. You are always right if your answers are supported in this way. You are doing a lot of work so you want to get full credit for it! Explanation of Checklist Download all needed files for the lab. You can find these either in the Lesson Resources, the links within the Lab lesson slides or in the Unit resources (scroll down to the lab). Lab Instructions (only use those posted in the lesson content or the lab materials folder) Student guide Laboratory Guidelines/Safety Graded Assignment or Lab Report for Discussion (LRD) (only use those posted in the lesson content or the lab materials folder) Study Lab Lesson Slides Attend live or watch recorded Classconnect for the lab if available. Prepare Data Tables: These include all data that has been collected during the lab. You are provided data tables in your instructions. Your choices to complete them include: Type directly, then copy and paste into the lab report or lab discussion post. OrUse Excel (you can still copy and paste the tables so you have the format and columns headers). Save and attach Excel file as additional file with your lab report or discussion. OrPrint out the instructions, handwrite in the data tables, then scan (pdf or jpg), copy and paste or attach as separate file. Set up lab and conduct experiment following instructions closely.

How to Identify the Common Black Walnut Tree

How to Identify the Common Black Walnut Tree Black walnut trees (Juglan  nigra) are found throughout much of the central-eastern part of the U.S., except in the far northern and far southern part of this range, but familiar elsewhere from the East Coast into the central plains. They are part of the general plant family Juglandaceae, which includes all the walnuts as well as hickory trees. The Latin name, Juglans, derives from Jovis glans, Jupiters acornfiguratively, a nut fit for a god. There are 21 species in the genus that range across the north temperate Old World from southeast Europe east to Japan, and more widely in the New World from southeast Canada west to California and south to Argentina. There are five native walnut species in North America: black walnut, butternut, Arizona walnut and two species in California. The two most commonly found walnuts found in native locations are the black walnut and butternut.   In its natural setting, the black walnut favors riparian zonesthe transition areas between rivers, creeks and denser woods. It does best in sunny areas, as it is classified as shade intolerant.   The black  walnut  is known as an  allelopathic tree: it releases chemicals in the ground that may poison other plants. A black walnut can sometimes be identified by the dead or yellowing plants in its vicinity.   It often appears as a kind of weed tree along roadsides and in open areas, due to the fact that squirrels and other animals harvest and spread the nuts. It is often found in the same environment as silver maples, basswoods, white ash, yellow-poplar, elm and hackberry trees.   Description Walnuts are specifically deciduous trees, 30 to 130 feet tall with pinnate leaves containing five to 25 leaflets. The actual leaf is attached to twigs in a  mostly alternate arrangement and the leaf structure is  odd-pinnately  compound- meaning that the leaves consist of an odd number of individual leaflets that attach to a central stem. These leaflets are serrate or  toothed.  The shoots and twigs have a chambered pith, a characteristic that can quickly confirm the trees identification when a twig is cut open. The fruit of a walnut is a rounded, hard-shelled nut. Butternuts are similar, but  this type of native walnut has oblong  ridged  fruits that form in clusters. The leaf scars on butternut have a hairy top fringe, while walnuts do not. Identification When Dormant During dormancy, the black walnut can be identified by examining the bark; the leaf scars are seen when leaves are pulled away from branches, and by looking at the nuts that have fallen around the tree. In a black walnut, the bark is furrowed and dark in color (it is lighter in butternut). The leaf scars along twigs look  like an  upside-down shamrock with five or seven bundle scars. Beneath the tree, you usually find whole walnuts or their husks. The black walnut has a  globose nut (meaning it is roughly globular or round), while the nuts on the butternut tree are more egg-shaped and smaller.

Academic integrity

Professional writing involves using clear language to explain themselves to an audience. 2. ) Integrity is important in writing because you should be honest to yourself and other people whom you are writing to. I believe that being in an online class helps you understand what integrity is and helps you be honest to people while you are opening up to them. For example in our discussion questions I feel like being honest is very important because it will keep my conversation going without any lies, it would be very e to be caught lying to someone while we are having a conversation.That is why it is important to have integrity. 3. ) The easiest way to avoid plagiarism is by using your own words. Once someone understands what plagiarism is and the consequences for doing it they will understand it much better. Quotations must be used when the paragraph is about 40 words or 3 sentences long. Like I said in my first sentence using your own words is the best way to avoid plagiarism is to use paraphrase. Paraphrasing means you should put the ideas in a passage into your own words, usually following the order in which the ideas were presented in the original paper.

Leisure and technology Essay Example | Topics and Well Written Essays - 500 words

Leisure and technology - Essay Example In the contemporary world, things have taken a different direction especially after industrialization. The aspect of leisure time activities has been intertwined with technology. In most cases, the leisure-time mobility and activities have tended to develop through technology use (Castle, 2006). The technological aspects, which had previously been developed for military, scientific and commercial purposes, have shifted towards leisure-time use. Currently, new technologies concepts have a leisure-time use phase. Alternatively, technological devices tend to serve as prototypes for various models which are then adapted for leisure time use. New researches suggest that pervasive technological tools tend to be killing off leisure activities. The younger generation is the mostly affected by the aspect of technology and leisure. In most cases, students and the younger workers tend to work for longer hours hence taking shorter vacations. If they decide to go for the vacation, all they do is take their laptops, tabs and cell phones along. Most organizations also tend to encourage this aspect by recommending the use of internet to do organizational chores while on holiday. Examples of leisure activities, which have been affected by technology, include games, book reading among others. In the contemporary world, children and even the young adults prefer computer games during their leisure and not the real game on the ground (Castle, 2006). Football is nowadays played over the internet. Alternatively, people prefer to watch football or any other game on the television instead of going to the stadium to watch it live. Nowadays people do not spend their free time reading novels and magazines. With the introduction of the internet, most people prefer reading online articles and books. With modernization, traditional forms of leisure have been replaced

What are the most important present and future foreign policy Essay

What are the most important present and future foreign policy challenges and what are the possible foreign policy options for dealing with those challenges - Essay Example The question then becomes how to fight for the values we believe in. America during this period and up until the present day has been trying to find foreign policy options that allow it to fight for what is believes in. The choice in a real sense has been between soft power and hard power. America has chosen the latter, while Europe has chosen the former. The Balkan Wars were one of the first stumbling blocks to the concept of a peaceful new world order. It turned out that having the US as the lone power in the world was not a solution to problems around the world. There was simply too much to be responsible for. As was demonstrated in the Balkans in the 1990s, Europeans weren’t able to project a credible military force even within Europe. This was a painful time for Europe. Instead of solving global conflicts, they looked inward. The Europeans resorted to the only real talent they had at the time: endless diplomatic measure through international institutions such as the UN. The success of European integration and solving the "German problem" had led a lot of Europeans at the time to believe that they live in a Kantian paradise where international institutions could banish war forever. This illusion came crashing down with the Balkans, where the Europeans were powerless in the early 1990s, and Chechnya, where they chose to tur n a blind eye, intimidated by an unstable and resurgent Russia, and unable to finding a compelling political reasons to engage. The truth is that America and Europe are very different and have different foreing policy goals and different methods of achieving those goals. Indeed, they have different values. There is reason to believe that the Americans and Europeans act differently. Americans are big and strong (both economically and militarily) whereas Europeans are relatively weak (especially militarily). This influences the way they see the world in a very profound sense. This means that America has to

Educating Rita by Willy Russell Essay Example for Free

Educating Rita by Willy Russell Essay Rita, Frank and their relationship change throughout the play. Ritas education and confidence both grow as the story progresses. Franks attitude towards life declines dramatically en route for the middle of the play but there is hint of improvement at the end. Their relationship undergoes many changes during the play. They grow apart, slowly and eventually reach a point where their separation is much needed and inevitable, although their feelings towards each other are of affection once again. At the beginning of the play Rita is a stereotypical working class girl, with little education and a lot of determination. She uses a lot of slang and colloquial language, stupid bleedin handle and off me cake, which shows her lack of education and her class. Rita appears ro be a confident girl, but she uses humour to cover up her nerves, thats what I do. Y know when Im nervous. Rita is also a lively, talkative person and very blunt and forthright. She shows this when she takes the pencil from Frank and scribbles out the letter S. Rita has a particularly determined character. At the start of the play she knows that she wants an improved life, with choices and she knows an education will give her that. So she is making sure she is going to get it, even at the cost of her marriage. When Rita leaves Denny she still wants to learn and discuss her Macbeth essay immediately. At the beginning of Act 2 Scene 2 Rita is seen oiling Franks door. This shows her determination and that she follows through her word, does what she says she will. Russell uses stage directions to show Ritas energy, the door bursts open and Rita flies in. The words flies and burst convey bubbly, lively movements and therefore her energetic character. At the start of this play Frank is a stereotypical upper-middle-class man. He is apathetic sarcastic and relatively independent. Frank uses Standard English and Received Pronunciation, showing his high class and good  education. He asks pardon? instead of what? and explains that the Open University is supposed to embrace a more comprehensive studentship. Frank is not dependant on anyone, but he drinks a lot and I think that he relies on alcohol a great deal. Therefore I would not say he is totally independent. Frank is very sarcastic and quick witted. He uses his sarcasm as a defence mechanism, or to make a point. He doesnt use it nastily or to hurt anyone. I sometimes get an urge to throw something through ita student usually. This shows him using sarcasm for humour but it also shows his disinterested, lazy attitude to life. Frank is bored of his life but, unlike Rita, he cannot be bothered to change it. He finds himself dull and tells Rita that she is the first breath of air thats been in this room for years. He does not want Rita as a student as he sees her as a lot of work, this shows his lazy attitude. However, the audience could also see this as a selfless and considerate moment. He does not want to take Rita on as a student as he does not think he is capable of teaching her. Frank is extremely clever and refers to high culture, such as T.S Elliot and Yeats, showing his high education and understanding. At the start of the play Frank is bored, funny, sarcastic, clever and shrewd. Frank and Rita get to know each other well and are very close, at the beginning of the play. They flirt and compliment each other, he doesnt half get on my tits/Frank: Good. Youll have to show me some evidence/Rita: Y dirty sod. And Right now theres a thousand things Id rather do than teach, most of them with you my dear. They trust one another and show this through discussion of their personal issues, I live with a girl. Ex-student. Shes very caring, very tolerant, admires me tremendously and spends a great deal of time putting her head in the oven. They then go on to discuss Julia and Franks relationship. Their ability to talk freely to each other shows that they are at ease in each  others company, relaxed and confident around one another. Nevertheless, their relationship is not always easy. It is hampered by their different frames of reference. At one point Frank thinks Rita is joking about T.S Elliot the poet, when in fact she is referring to Elliot Ness, y know, the famous Chicago copper who caught Al Capone. At another point Rita is calling Frank a Flora man from the advert for the butter: flora. Frank assumes she means flora as in flowers. However, Frank and Rita have a mutual understanding of each other, which helps them work through and get beyond their misunderstandings. Their differences intrigue and fascinate one another. This helps keep their relationship alive and fresh. In the middle of the play we see dramatic changes in Rita. Right at the beginning of Act 2 Russell indicates a change by Rita entering wearing new second hand clothes. Rita is at a very difficult point in her change. She has come so far and cannot go back to where she used to be, but she is finding it difficult to carry on, she is half way and stuck in between two worlds. Rita chooses to persevere. Rita has much more confidence and is using humour to hide behind less. She is more educated and has been influenced by lots of people over the summer. Her confidence shows when she tells Frank about summer school. She explains how she asked a question even though everyone was looking at her and two thousand people had seen me stand up. She then goes on to say, after that I was askin questions all week. Before summer school Rita wouldnt have dared do something like that. As well as her confidence improving she is now using more Standard English, although still using colloquial language. Summer has had some less positive effects on Rita, too. She has been very influenced by Trish and although she has now got a better understanding of literature she still does not have her own views. She has merely swapped Franks opinions for Trishs opinions. Frank comes back from holiday even more fed-up with life than before. Rita asks him what France was like, marvelling at the opportunity to go abroad. Frank gives an uninterested answer of well it was rather hot. He is very dismissive, taking for granted the occasion of going abroad and his answer is slightly hostile and cold. He seems to be more apathetic and very low, not recognising that he has got so much going for him. it is indeed because I have got so much going for me that I do itI need the drink to help me step delicately through life. This comment shows that he is still using sarcasm, it shows his sad view on his life and he tells us that he needs drink. This informs us that he has become very reliant on drink. He is worse than he was before, turning up to lectures drunk and not taking anything seriously. He does not even bother to hide the drink anymore. He carries it, in his briefcase, to lectures. The briefcase symbolises work, so to carry alcohol in it shows just how little he cares. Frank now chooses to ignore his education; Rubyfruit Jungle is excellent. He is reverting to how Rita was. Whereas, Rita now has a view, shows her understanding and expresses it formally. They have echoed each other. Franks language has also changed. He is reiterating phrases from Rita, completely off me cake, and he has picked up some of her slang. He is still sarcastic, but sometimes in a hostile, jeering way, like when he shouts names at Rita Charlotte? Or Jane? Or Emily? At the mid-point in the play Frank is hopeless, he challenges Rita saying and well all live happily ever after? Saying this squashes dreams, is sarcastic and apathetic and takes a completely pessimistic outlook on life,  his decline is continuous. Their relationship dwindles when they meet again after summer. The changes in Rita have a big role to play in the downward spiral of their relationship. Rita is becoming more independent, She needs Frank less, he begrudges her this and it causes tension. Dont y like me now that the little girls grown up, now that y can no longer bounce me on daddys knee an watch me stare back in wide eyed wonder at everything he has to say? They understand each other less and know little about each others lives. It struck me there was a time you told me everything, Frank is wistful and shows a sense of longing. He feels Rita slipping away, I cant bear you anymore, he tells her, you dont have to put in a visit out of sentimentality. They no longer have a close relationship and Frank misses and feels bitter about that. They become increasingly resentful towards each other. Frank start to get jealous and resentful of Trish, this feeling fuels further conflict. Will you kindly tell Trish that I am not giving a tutorial to a Dalek. This remark shows coldness in their relationship, the warmth, flirting and friendly banter has gone. At the end of the play Rita has more choices than before, she is educated, confident and able to think for herself. Rita is undecided what the next step in her life should be, but she now has a choice and this is what she set out for: to be able to choose. I might go to France. I might go to my mothers. I might even have a baby. I dunno. Ill make a decision, Ill choose. I dunno. She is educated now and has passed her exam. Arguably more important is that she is no wise. She can think for herself, think logically and develop her own opinions. You woulda loved it if Id written Frank knows all the answers across me paper, wouldnt y? However, Rita did not and this shows  her education and thinking skills. She uses Standard English more now, such as scholarly neckline. Again showing her education. Rita is no longer hiding behind humour, but she is genuinely confident and still funny. Probably the biggest change in Rita from beginning to end is that she now understands Franks views and realises he was and is on her side. She places a Christmas card with the others already there. The card is a token of friendship and signifies her realisation that what she had was not all that valuable. Her realisation shows how she has matured, changed her way of thinking and now feels more kindly for Frank. Frank is now sober and hints that he will make a change in his life. There is now some optimism. He is trying to think well of his move to Australia, things are just beginning there this implies he will take this as an opportunity to start fresh, itd be good for us to leave a place thats just finishing for one thats just beginning. Frank accepts the changes in Rita and shows his thoughtful side when he gives her the dress. He also has a realistic moment and says, I was rather pissed when I bought it. He is not pretending to be a reformed character and he is reminding the audience of his drinking and old habits. Frank is now using Standard English again, metaphorically. And as it was metaphorically the sentence was reduced from the sack to two years in Australia. He is still humorous, Forsters lager they call it, and is sarcasm is still there, but it is no longer hostile. Although Frank is in a worse position than at the start of the play there is hint of improvement and a better life. Ritas response to Trishs suicide and Franks realisation of the need to change has resulted in a greater mutual understanding and a friendlier relationship. I knew how much it had come to mean to you. Frank did not like Rita in the middle of the play but understands why she was like that. They both accept the changes in each other. Rita now appreciates all the help Frank gave her, I came to tell you youre a good teacher. Frank realises her learnt a lot from Rita, too, all Ive ever done is taken from you. Ive never given anything/Frank: thats not true. Youve They understand that they have got to go their separate ways now, and move their lives on, but they part on good terms. Rita begins as a stereotypical working-class girl, with a poor education, who hid behind humour. She goes through a series of changes and ends the play as a confident, wise, educated young lady, ready to make her own choices and get on with her life. Frank begin as a upper-middle-class man, he was very sarcastic, had a poor attitude towards life and relied on drink. As the book progressed he developed a serious drinking problem, became more and more apathetic and finally reached a point where he was on the verge of being sack. He eventually starts to get things into perspective and hints at a brighter future. The relationship between Rita and Frank began well, they complimented and trusted one another. They drifted apart and argued in the middle, but reconciled their relationship and parted on good terms. I think the main change in Rita was that she started with no choices, she had a hunger for more and great determination, which resulted in her gaining the ability to choose, and to choose wisely. I think this change in Rita was conveyed very well because as the story progresses we saw her make many decisions along the way. We saw how the choices she had to make got bigger  and bigger and how her ability to deal with the choices got better and better. The book finished with her thinking about the biggest choice; whether to have a baby or not. I think Franks character was portrayed well via his language and through his drinking habits. I really enjoyed the book and thought Russell kept me interested by adding new details along the way, we learnt more about the characters private lives as the story continued and this was an added interest. I think that the book had a good ending, as it was realistic. It showed how what they had done throughout the book and what choices they had made affected their position at the end of the book. This emphasised the theme of choice again.

Guilty Conscience in Macbeth :: essays research papers

In my opinion, the statement â€Å"If you commit a crime and don’t get caught, it doesn’t really matter because your guilt over what you have done will destroy you in the end† is true and happens in reality. What is a crime? It is an evil act that breaks the law or the basic values of the society, harming the individuals of the society. So if you commit a crime, and don’t get caught the fact that you have committed a crime and your heart knows will haunt you forever and make you feel guilty. If you know that the act you did was wrong, but you did it anyways ignoring what you knew will definitely lead to your destruction. Even though, you would appear to be confident to others, after committing the crime, but your inner conscience will always curse you and will eventually destroy you. This is what happened to Lady Macbeth in the play written by William Shakespeare, â€Å"Macbeth†. When Macbeth informed Lady Macbeth of the witches’ prophecy of him being the king of Scotland, she incited him to kill Duncan (because of her desire or ambition to rule Scotland). She could not kill Duncan herself, so she told him to slay Duncan. Even though, Lady Macbeth did not kill Duncan, she knew it was because of her provocation that Macbeth was forced to take this step. In the beginning of the play, she is blood thirsty and cruel. In the middle, when she had to hide Macbeth’s hallucination of seeing Banqous ghost, she said â€Å"Good friends, think of this as nothing more than a strange habit. It's nothing else. Too bad it's spoiling our pleasure tonight† (III, iv, 101-103). She is still confident and is trying to stabilize Macbeth’s thoughts. Till this point she is not shown to be guilty of her act but confident. Gradually, as the play progresse s we hear about Lady Macbeth’s condition from her maid, who says to a Doctor â€Å"Since his majesty went into the field, I have seen her rise/from her bed, throw her nightgown upon her, unlock her/closet, take forth paper, fold it, write upon 't, read it,/ afterwards seal it, and again return to bed, yet all this/while in most fall asleep† (V,I, 3-8). Then Lady Macbeth says while sleep walking â€Å"Out, damned spot! Out, I say!—One, two. Why, then, 'tis time to do 't/. Hell is/murky!—Fie, my lord, fie! A soldier, and afeard?

Definitions of Optical Coupler, Resistor and Transistor

Optical coupling is a portion that exchanges electrical flags between two separated circuits by using visible radiation every bit indicated as a portion of Fig.6.4. It keeps high electromotive forces from act uponing the model accepting the mark. Industrially accessible opto-isolators with stand information to-yield voltages up to 10 kilovolts and electromotive force homeless people with gaits up to 10 kV/ & A ; mu ; s. A typical sort of opto-isolator comprises of a Drove and a phototransistor in the same package. Opto-isolators are by and large utilized for transmittal of advanced ( on/off ) marks, nevertheless a few schemes permit use with simple ( matching ) marks. An opto-isolator contains a beginning ( emitter ) of visible radiation, rather frequently a close infrared Light-Emanating Diode ( Drove ) , that changes over electrical information signal into visible radiation, a unopen optical channel ( to boot called di-electrical channel ) and a exposure detector, which distinguishes nearing visible radiation and either creates electric verve specifically, or regulates electric current sloping out of an outer power supply. The detector can be a exposure resistance, a photodiode, a phototransistor, a Silicon-Controlled Rectifier ( SCR ) or a triac. Since LEDs can feel light notwithstanding radiating it, development of symmetrical, bidirectional opto-isolators is imaginable. An opto-coupled strong province hand-off contains a photodiode opto-isolator which drives a force switch, usually a correlate brace of MOSFETs. An opened optical switch contains a wellhead of visible radiation and a detector, nevertheless its optical channel is unfastened, all owing ordinance of visible radiation by outer points hindering the manner of visible radiation or reflecting visible radiation into the detector A resistance is a two-terminal electronic section intended to curtail an electric current by making a electromotive force bead between its terminuss in extent to the present, that is, as per Ohm & A ; apos ; s jurisprudence. Resistors are utilized as a constituent of electrical systems and electronic circuits. They are to a great degree typical in most electronic cogwheel. Handy resistances can be made of different mixes and films, and in add-on opposition ( wire made of a high-resistivity complex, for illustration, nickel/chrome ) . The indispensable properties of resistances are their opposition and the force they can circulate. Different attributes integrated temperature coefficient, blare, and induction. Less no uncertainty understood is know aparting opposition, the quality beneath which control airing restrains the greatest allowed current watercourse, or more which the breakage point is connected electromotive force. Basic opposition relies on the stuffs representing the resistance and its physical measurings ; its controlled by constellation. Resistors can be incorporated into mixture and printed circuits, and coordinated circuits. Size, and place of leads ( or terminuss ) are of import to gear conceivers ; resistances must be physically sufficiently expansive non to overheat when scattering their energy. Variable resistances are movable by altering the place of a contact on the resistive constituent, for illustration, with a versatile skiding contact, known as a potentiometer. There are extraordinary kinds of resistance whose opposition alterations with different sums, the bulk of them have names, and articles, they could name their ain: the opposition of thermal resistors displacements tremendously with temperature, whether exterior or because of airing, so they can be utilized for temperature or current detection ; metal oxide varistors drop to a low opposition when a high electromotive force is connected, doing them suited for over-voltage confidence ; the opposition of a strain pot differs with mechanical load ; the opposition of exposure resistances fluctuates with enlightenment ; the opposition of a Quantum Burrowing Composite can differ by an component of 1012 with mechanical weight connected ; etc. The appraisal of a resistance can be measured with an ohmmeter, which may be one capacity of a multimeter. Normally, trials on the coatings of trial leads interface with the resistance. A gate driver is a power amplifier that accepts a low-power input from a accountant IC and engenders a high-current thrust input for the gate of a high-octane transistor such as an IGBT or power MOSFET. Gate drivers can be provided either on-chip or as a distinct faculty. In kernel, a gate driver consists of a quality shifter in pile with an amplifier. It is frequently verbalized that transistors such as MOSFETs with stray gate electrodes can be driven without a authority beginning, which is non real. In contrast to bipolar transistors, MOSFETs do non necessitate changeless power input, every bit long as they are non being switched on or off. The stray gate-electrode of the MOSFET forms a capacitance ( gate capacitance ) , which must be charged or discharged each clip the MOSFET is switched on or off. As a transistor requires a peculiar gate electromotive force in order to exchange on, the gate capacitance must be charged to at least the needed gate electromotive force for the transistor to be switched on. Similarly, to exchange the transistor off, this charge must be dissipated, i.e. the gate capacitance must be discharged. When a transistor is switched on or off, it does non instantly exchange from a nonconductive to a conducting province ; and may transiently back up both a high electromotive force and carry on a high current. Consequently, when gate current is applied to a transistor to do it to exchange, a certain sum of heat is engendered which can, in some instances, be plenty to harry the transistor. Therefore, it is indispensable to maintain the switching clip every bit abruptly as possible, so as to minimise switching loss. Typical shift times are in the scope of microseconds. The switching clip of a transistor is reciprocally relative to the sum of current used to bear down the gate. Therefore, exchanging currents are frequently required in the scope of several hundred mill-amperes, or even in the scope of amperes. For typical gate electromotive forces of about 10-15V, several Watts of puissance may be required to drive the switch. When astronomically huge currents are switched at high frequen ces, ( e.g. in DC-to-DC convertors of sizably voluminous electric motors ) , multiple transistors are sometimes provided in parallel, so as to supply sufficiently high exchanging currents and exchanging authority. The switching signal for a transistor is conventionally engendered by a logic circuit or a microcontroller, which provides an end product signal that typically is constrained to a few mill-amperes of current. Consequently, a transistor which is straight driven by such a signal would exchange really bit by bit, with correspondingly high power loss. During exchanging, the gate capacitance of the transistor may pull current so efficiently that it causes a current over draw in the logic circuit or microcontroller, doing overheating which leads to dateless harm or even masterful ravagement of the bit. To debar this from transpirating, a gate driver is provided between the microcontroller end product signal and the authority transistor Each MOSFET is bulwarked against dv/dt and di/dt rampart as shown below

Business Model Comparison Most small businesses require some outside funding. Not many entrepreneurs have enough personal capital to open and maintain funding for a business. To attract investors and attain partnerships, a business owner should consider a business model necessary. This paper will compare two restaurant businesses, identify the business model and forms of ownership for each business by completing a Comparison of Business matrix, describe benefits by building a sustainable competitive advantage, and giving advantages and disadvantages of each business ownership. Great introduction. You state the purpose and what you plan to address! McDonald’s restaurants are among the most recognizable in the world. Their quintessential arches can be identified in almost every country. This fast-food mogul is one of the biggest and most profitable corporations in the industry (what industry?

Benefits To Building A Competitive Advantage When evaluating the benefits of each business, it is important to consider the size of each business. As an example, both sole proprietorships and partnerships are relatively small in size and may perhaps provide more personalized service to each of their clients. In many businesses, customers appreciate personalized service and may in turn hire small businesses for that service. On the other hand, a larger business, like McDonald’s, typically is composed of more resources and may offer the prospective customer a lower price. Another competitive advantage of a smaller business, like Datillo’s, is the ability to provide customers with a higher level of quality. Because customers of small businesses deal more closely with a ‘tight nit’ group of employees, the quality and service provided to the customer is much greater than a larger corporation composed of numerous locations. Both small and large businesses each have distinct advantages that enable them each to thrive. Although some customers may appreciate the more personalized service of small businesses, others may prefer a lower price and a larger name brand. Make sure paragraphs are a minimum of 3 sentences!

Art in the field - Assignment Example Initially designed to serve as a private get-a-away for the family that bought the area, the Hakone Garden was influenced by the family’s visit to Japan and their admiration for the local architecture and landscaping present there. Japanese landscape artists and architects helped to bring their vision to reality while maintaining an air of authenticity for the garden. The garden is set in layers which allow the visitor to experience each different section in leisure and to really absorb their charms. Though the Garden is smaller as compared to other national or specialty parks this works to bring to a picturesque quality to the whole setting and for those who are truly looking to experience the Japanese ‘art’ it is very easy to spend hours just strolling among the landscape. Personally the section which attracted me the most was the Bamboo garden. These tall ‘grass’ are an oddity when compared to the natural forests we are used to; the long and slender stalks reaching up to meet the sky create a very unique world to walk through. There is a strength depicted in the garden where so many bamboos stand together to create a curtain of green and it can be intimidating in a sense. The serenity of the place when combined with this deeper strength creates two layers of meaning to the section and this is why I felt most attracted to it. The Koi pond was a beautiful and the fish in no little way contributed to that. The flashing red of the fish when contrasted with the blue flowing water made for a very eye-catching combination. At the time of my visit, preparations were going on for a wedding to be held in the afternoon. The beautiful backgrounds make for a unique photo shoot, and many people admire the opportunity to indulge in a different culture while celebrating their special days. The garden presents a window into the heritage of the

Control a People's Language - Essay Example Instead, they start by using sign language to communicate with their significant others. They learn such signs from the people who take care of them, thus highlighting their dependence on such individuals. Consequently, the caregivers of such children have the capacity to control the children as they take charge of their language. A look at the deaf community also highlights this important aspect. When children are born deaf, their caregivers take up the role of using signs that the young ones can use as their language of communication. Therefore, the caregivers control the deaf children as they teach them a unique and informal language unknown to other people. This creates a form of control since other people outside the circle of the caregivers may not understand the language. At the national and international levels, the people in charge of formulating such languages as the American Sign Language also control the communities that use the sign language. This is because the people invent signs that apply on a national level. Consequently, the deaf community, for instance, is compelled to use the language for them to contribute to nation building. The most conversant people in this language also possess the ability to advocate for the rights of such people. They can do this by raising awareness of the challenges faced by such people, thus promoting their voice in the nation. Such actions lead to greater recognition of the deaf communities, and may stop them from being classified as minorities (Jaspers, Verschueren & Ostman, 2010). P. 187. On the other hand, the people who possess such skills, as well as the ability to advocate for the rights of the deaf can choose to keep silent, thus hindering the ability of the deaf to get equitable opportunities. This explains that being in control of a people’s language leads to their control as the people get to decide what is to be done, and what should not be done. In
