Introduction Of Fiber Optics Essay Example For Students

Introduction Of Fiber Optics Essay Fiber OpticsAssignmentMany modern medical materials and equipment work on a principle which isbeyond the capacity of human transducers. Comment and discuss the working principles of an endoscope, uteroscopeor a rectoscope showing the illuminating path, the image path, transmission pathand the liquid transfer or operating instrument ducts, showing the position ofsuitable valves. This will therefore explain how light travels through an optical fibreand show how such fibres are used in medicinal equipment either to transmitlight or to bring back images from within a patient.

The clear advantages of fibre optics are too often obscured by concerns thatmay have been valid during the pioneering days of fibre, but that have sincebeen answered by technical advances. Fibre is fragileAn optical fibre has greater tensile strength than copper or steel fibres of thesame diameter. It is flexible, bends easily, and resists most corrosiveelements that attack copper cable. Optical cables can withstand pulling forcesof more than 150 pounds. Fibre is hard to work withThis myth derives from the early days of fibre optic connectors. Earlyconnectors where difficult to apply; they came with many small parts that couldtax even the nimble fingered. They needed epoxy, curing, cleaving and polishing. On top of that, the technologies of epoxy, curing, cleaving and polishing werestill evolving. Today, connectors have fewer parts, the procedures for termination are wellunderstood, and the craftsperson is aided by polishing machines and curing ovensto make the job faster and easier. Even better, epoxyless connectors eliminate the need for the messy and time-consuming application of epoxy. Polishing is an increasingly simple,straightforward process. Pre-terminated cable assemblies also speedinstallation and reduce a once (but no longer) labour-intensive process. Fibre Optic BundlesIf light enters the end of a solid glass rod so that the light transmitted intothe rod strikes the side of the rod at an angle O, exceeding the critical angle,then total internal reflection occurs. The light continues to be internallyreflected back and forth in its passage along the rod, and it emerges from theother end with very little loss of intensity. This is the principle in fibre optics of which long glass fibres of very smallcross-sectional area transmit light from end to end, even when bent, withoutmuch loss of light through their side walls. Such fibres can then be combinedinto bundles of dozens to thousands of fibres for the efficient conveyance oflight from one (often inaccessible) point to another. If the glass fibre comes into contact with a substance of equal or higherrefractive index, such as an adjacent glass fibre, dirt or grease, then totalinternal reflection does not occur and light is lost rapidly by transmissionthrough the area of contact. To avoid such leakage and to protect the fibres,they are clad in glass skins of refractive index lower than that of the fibrecore. As the angle of incidence I increases, Rincreases and O ( = (n/2) -R)decreases. Eventually, O reaches C, the critical angle, and any furtherreduction in O results in transmission through the side wall. The expression n0 sin Imax is called the numerical aperture of the fibre. Atypical value for this might be 0.55, making Imax about 33o in air. SometimesImax is referred to as the half-angle of the fibre, since it describes halfthe field of view acceptably transmitted. The numerical aperture (and henceImax) can be increased by using a core of high refractive index. However, theseglasses have a lower efficiency of transmission, especially at the blue end ofthe spectrum, and are not commonly used. .u0b218f752235a9266fd3d91d66934ca9 , .u0b218f752235a9266fd3d91d66934ca9 .postImageUrl , .u0b218f752235a9266fd3d91d66934ca9 .centered-text-area { min-height: 80px; position: relative; } .u0b218f752235a9266fd3d91d66934ca9 , .u0b218f752235a9266fd3d91d66934ca9:hover , .u0b218f752235a9266fd3d91d66934ca9:visited , .u0b218f752235a9266fd3d91d66934ca9:active { border:0!important; } .u0b218f752235a9266fd3d91d66934ca9 .clearfix:after { content: ""; display: table; clear: both; } .u0b218f752235a9266fd3d91d66934ca9 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u0b218f752235a9266fd3d91d66934ca9:active , .u0b218f752235a9266fd3d91d66934ca9:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0b218f752235a9266fd3d91d66934ca9 .centered-text-area { width: 100%; position: relative ; } .u0b218f752235a9266fd3d91d66934ca9 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0b218f752235a9266fd3d91d66934ca9 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0b218f752235a9266fd3d91d66934ca9 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u0b218f752235a9266fd3d91d66934ca9:hover .ctaButton { background-color: #34495E!important; } .u0b218f752235a9266fd3d91d66934ca9 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0b218f752235a9266fd3d91d66934ca9 .u0b218f752235a9266fd3d91d66934ca9-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0b218f752235a9266fd3d91d66934ca9:after { content: ""; display: block; clear: both; } READ: Marvell vs Herrick EssayThe above analysis applies only to a straight line fibre.

What it Means to be a Global Citizen Essay Example

What it Means to be a Global Citizen Essay There is indeed too much diversity in our world today. Different races, various cultures, divided geographies and opposing beliefs separate each state or country from each other. The world is a very diverse place with a little hope to for global unity. Countries fight over territories. Leaders battle over power. Governments take advantage of their constituents. Racism raises social injustice among multiracial societies. All of these social problems create an unnecessary segregation of various groups in our planet. There is too much nationalism going on that we tend to forget what unity is all about. Upon encountering the word â€Å"global citizen†, what immediately comes to my head is the image of a person deeply concerned with the world around him as a whole regardless of race or geography. This person sees the world in one piece without any barriers such as race, culture or geography. A global citizen for me does not limit him—or herself within his or her native land or hometown. According to Elizabeth Kruempelmann, the author of The Global Citizen: A Guide to Creating an International Life and Career, â€Å"Global citizens are global-minded people like you and me who crave international experience and are passionate about living fulfilling lives† (1). She defines the term as any person who has the passion to live a diverse way of life by the involvement of different cultures, languages etc. She also added that, â€Å"The term ‘global citizen’ creates awareness of a whole category of internationally oriented people who derive satisfaction from life by discovering the world† (1).

The most significant realization here is the fact that I am and can be considered as a global citizen. I love life and enjoy traveling. I am very much concerned with how the economic, political and social circles operate in the world. I lived in Pakistan for quite a long time and studying in the United States of America have taught me how important it is to take notice of all the other countries worldwide. Most especially today when the threat of global crisis is endangering the world’s economic growth, it is the best time for each one of us to become concerned not merely as a national citizen but rather a global citizen who is determined to make a change for a better world. It is time that we stop thinking exclusively for our own nations. It is the best time for us to start anew as a citizen who is concerned for the world as a whole nation. A global citizen can either be you or me. It can be anyone who has a taste for diversity and readiness to accept differences as part of a whole. It can be an international student like me who wishes to study abroad to learn new ideas apart from my traditional education back from my hometown. It can be a traveler who enjoys discovering new places and foods which fulfills his very purpose. It can be any language teacher wanting to share his or her native language to foreign people. Most important of all, it can be everybody who wishes to make this world a better place by uniting them. Works Cited Kruempelmann, Elizabeth.

Computer Upgrade Essays - Classes Of Computers, Digital Electronics

Computer Upgrade With increasing popularity of computer games, and multimedia home PC users often need an unexpensive computer system upgrade. By building a custom computer one is able to combine componenets, and operating system to provide maximal gaming performance. Computers are often called number manipulators, because of their ability to run millions of mathematical operations per second (White 43). Computers use binary system of numbers, which allows them to operate system of microscopic switches called transistors found inside of computer chips. Binary system is defined as counting system that uses two digits one and zero (Gookin 49). A transistor is a basic building block of microchips; transistors are combined in formations called logic gates (White 39). "Transistor can only create binary information: one if current passes through or zero if current does not, to work with transistors"(White 39). Computer software uses Boolean logic, which is based on selecting true or false values used in computer programming (White 39). All personal computers have BIOS, which is an acronym for Basic Input Output System. The BIOS runs every time the computer is started, and it basically tells the computer how to act (White 19). The BIOS is a part of the boot up process, or a complex set of operations checking hardware that components are working properly. Besides BIOS and several other operations there is power?on self-test - POST being ran. POST test runs at the start up, and if it finds an error, it sends a warning message (White 5). Central processing unit ? CPU is the most important part of the personal computer, all other components work as a bridge to CPU (White 59). The speed of the processor is usually defined by using units called megahertz (MHz, also million frequency waves per second). CPUs are generally divided into two categories- CISC and RISC. CISC ? complex instruction set computing, uses many small instructions to carry out a single operations. CISC is a standard in today's processors. RISC ? reduced instruction set computing, uses less complicated instructions with simpler design. RISC microprocessors are cheaper, they produce less heat, and they are generally smaller in size compared to CISC. With less heat and smaller size RISC processors have great advantage in reaching higher frequencies with less danger of overheating. The major disadvantage and also reason why RISC microprocessors are not widely used, is less compatibility with available software. The earlier programs were written for CISC chips. In order to reach maximal speed, and compatibility the major manufacturers of microprocessors such as Intel, use some advantages of RISC technology, to improve the performance of their CISC compatible microprocessors (White 55). Computer microprocessor is the most important part of the PC, but it can not work by it self. One of the few primary components is BUS, also called a highway of the computer. BUS transports data among the processor, random access memory, and hard disk. Speed of the BUS depends on the type of motherboard where it is installed (White 119). Random access memory- RAM is also attached to the motherboard- base of all the components, but unlike BUS, RAM can be easily removed and changed. Random access memory works as a staging area for the central processing unit (White 43). Capacity of random access memory is very important for the performance of a computer. In case there is not enough RAM the software can create space on the hard drive to be used as temporary operating memory (White 31). Random means that any part of the memory can be accessed at any time, it is not necessary to read all of the memory to find one location. RAM is usually fast, temporary memory where data is saved until removed or power is turned off on the computer (White 43). "A hard drive is the workaholic of a PC system."(White 87)) It is based on using magnetic plates; spinning at extreme speeds up to 7,200 rotations a minute, which are 120 spins every second. Even with extreme speed and microscopic accuracy modern hard drives are unlikely to fail. The hard disk is a combination of electronic and mechanical portions, which makes it the one of the slowest parts of the computer (White 87). A graphic card is usually plugged into one of the expansion slots, which are metallic contacts on the motherboard (White 119). One of the most common expansion slots is PCI ? peripheral components interconnect. PCI are most commenly white slots used to attach a graphic or sound card, also modem or network card (White 120). Latest expansion slot used for

What Are Good SAT Scores for Colleges 101 Schools + Advice

What Are Good SAT Scores for Colleges 101 Schools + Advice SAT / ACT Prep Online Guides and Tips As you apply to college, it's important to understand how high of an SAT score you will need to aim for on test day. This raises the question:what aregood SAT scores for colleges? And notjust any colleges, but your colleges specifically? In this article, we’ll examine the SAT scores needed for college and how these scores can varydue todifferences in factors such as school prestige and competitiveness. We’ll then show you how to look for average SAT scores for colleges and how to set your own SAT goal score. What Are Good SAT Scores for Colleges? First off, what are good SAT scores for colleges? In reality, there's no single answer to this question because good SAT scores for universities vary depending on where you’re applying. For some schools, an SAT score of 1400 will be significantly high, whereas for others (i.e., top-20 colleges) it’ll be fairly low. As you might've guessed, ultra-competitive,top-ranked schools typically look for some of the highest SAT scores in applicants. Below is a chart containing thetop 25 US schools (as ranked by US News) and their ranges of SAT scoresfor incoming students. This data highlights the SAT score you'll need to get in order to give yourself the best shot at securing admissioninto ahighly competitive school.For each school, we give you theaverage SAT score, 25th percentile score, and 75th percentile score of incoming students. A 25th percentile score means that 25% of students scored at or below this threshold, while a 75th percentile score means that 75% of students scored at or below this threshold. Thus, the 25th and 75th percentiles represent the middle 50% SAT scores of admitted applicants- the average SAT score range for a particular school.GoodSAT scores for universities are usually those in the 75th percentile or higher (i.e., anything above the middle 50%). Note:For those curious about what kinds of SAT scores are required for Ivy League schools, I’ve bolded all eight Iviesin the table below. This should make it easier to compare the SAT scores of Ivies with those of non-Ivies.

By contrast,Caltech maintains the highest SAT scores:only 25% of incoming studentsscored at or below 1530- an extremely impressive SAT score in the 99th percentile! Even more impressive, a whopping 75% of Caltech students scored at or below a near-perfect score of 1590. Top schools are like center brownies: lots of people compete for them, but only a few will win access to one. But what if you’re not interested in applying to only top-25 schools? To lend you a hand, we've gathered SAT score information for 76 additional schools.All of the schools selected for this listare relatively well known- some more so in their respective regions- andvary from large public institutions to small liberal arts colleges. Whereas some are extremely competitive, others are more laid-back. But all are definitely worth considering for college!

How to Find Average SAT Scores for Colleges With these two charts, we've given you- in addition to the 25th and 75th percentile SAT scores for each school- the average SAT scores of admitted applicants. These averages tell us what kinds of SAT scores you shouldaim for in order to match (or even possiblyexceed!) the qualifications of previously admitted students. But where can you findaverage SAT scores for colleges? The two best resources to look for SAT averages are ourPrepScholar database andofficial school websites. Method 1: Use the PrepScholar Database We at PrepScholar maintain a robust databaseyou can use to get more information onthe SAT scores needed for college. Start by typing in "[School Name] PrepScholar"or "[School Name] PrepScholar SAT"on Google. For example, here's the page I got when I searched for "university of oregon prepscholar": Click the link to either your school'sAdmission Requirements page orSAT Scores and GPA page in our database. I decided to look at the University of Oregon's Admission Requirements page(the first link in the screenshot above). Once on your school's PrepScholar page, scroll down to look for a section about its SAT scores. Straight away, you should be able to spot your school'saverage SAT score in a blue banner: If you'd like to see the 25th and 75th percentile SAT scores for your school as well, simply scroll down to look at the percentile chart: This is all you need to do to find the average SAT scores for colleges. However, if you’re having trouble locating a specific school in our PrepScholar database, move on to Method 2. Method 2: Use Official School Websites This method involves lookingfor SAT score information on aschool's official website.The easiest way to do this is to hop on Google, search for "[School Name] average SAT scores," and then click any links to official pages discussing SAT scores for your school. Another (slightly less convenient) method is tobrowseyour school'swebsite and intermittently usectrl + F to look for anymentions of SAT scores. The best pages to searchare those offering information onadmission statistics, the new freshman class, and facts and figures. That said, not allschools report average SAT scores. Whereas some won't release any SAT score information at all,other schools might report SAT scores of admitted applicants in the form of 25th and 75th percentile scores. One example of this is Princeton, whichoffers middle 50% SAT score ranges for both sections on the SAT. According to this Ivy League school, the middle 50% is 730-790 for Math and 700-770 for Evidence-Based Reading and Writing. In other words,25% of students scored1430 or below and 75% of students scored 1560 or below. Although this range isn’tthe same as an average, it does give us the information we ultimately want to know:what kind of SAT scores are considered better than average (and below average) at this particularschool. This freakishly beautiful kitten is anything but average. How to Set an SAT Goal Score We've seen how widely SAT scores for universities can vary; now, it’s time to figure out what score you'll need for your colleges specifically. In other words, what shouldyourSAT goal score be? A goal score is the SAT score most likely to get you into at least one of the colleges you're applying to (excluding safety schools). Ideally, it'll get you into all of them! Because SAT expectations can vary greatly by school and because there's such an enormous array of colleges you can apply to,your SAT goal score will be yours and yours alone.Other students might have higher or lower goal scores than you- but none of that matters. In the end, what does matter is your goal score’s likelihood of getting you into the college of your dreams! To find your SAT goal score, follow these three simple steps. Step 1: Make a Chart First off, make a table for the schools you're applying to and their 25th/75th percentile SAT scores. You may download our worksheet or draw a table similar to the one below. On the left, list all the schools you plan to apply to (excluding any safety schools you’re about90% certain you’ll get into). Here's an example: School 25th Percentile 75th Percentile UT Austin Texas AM Baylor TCU Step 2: Find SAT Score Info Online Your next step is to look for SAT score information for each of the schools in your table.To do this, follow the same steps as outlined in Method 1 for finding average SAT scores for colleges. Once again, here are the steps you'll need to take: Step 1: Search for "[School Name] PrepScholar SAT" on Google and click on the PrepScholar page for your school (either the Admission Requirements page or SAT Scores and GPA page will work). Step 2: Scroll down to the SAT section on this page to find a chart listing the 25th percentile, 75th percentile, and average SAT scores for this school. Step 3: Recordthe 25th and 75th percentile scores in your chart. In addition to using our database, you can search for "[School Name] SAT scores" on Google and look for official web pagesfor your school. Many schools will report either average SAT scores or the middle 50% of SAT scores(which is what you'll want for your chart). As a reminder, the minimum score in a 50% range is the 25th percentile, and the maximum is the 75th percentile. Once you've found SAT score information for all your schools, your chart should look like this: School Name 25th Percentile 75th Percentile UT Austin 1160 1390 Texas AM 1140 1360 Baylor 1190 1360 TCU 1130 1330 Step 3: Find Your Target Score Now, you’ll use the information in your chart to findyour target SAT score. To do this, simply look for the highest 75th percentile score in your chart.This will be your SAT target score. You must hit this (or near this) score in order to give yourself the best chance of admission to all the schools you're applying to. In this case, my goal score would be 1390 (for UT Austin), as this is the highest score in my chart. To figure out your (estimated) goal scores for each section (Evidence-Based Reading and Writing + Math), you candivide your goal score by 2.So a composite 1390 goal score would come out to a 690-700 EBRW goal score and a 690-700 Math goal score. My goal score? 100% completion in Breath of the Wild. (Brett Chalupa/Flickr) Summary: What Are Good SAT Scores for Colleges? Simply put, there is no one definition for good SAT scores for colleges.
