Voice over Internet Protocol(VoIP) By: Michael Johnson VOICE OVER INTERNET PROTOCOL (VoIP) INTRODUCTION: In the eyes of most, all packets are created equal. One of the most active areas of telecommunications today is in the area of Voice over Internet Protocol (VoIP). The logic behind this trend makes perfect sense. If we have invested heavily in an Internet Protocol (IP) network, why can’t we make full use of it? This is a question posed by many managers and Information Technology (IT) professionals in a wide range of businesses. Many businesses would prefer to have one network in and out of their business for reasons ranging from cost effectiveness to manageability. IP telephony offers a promise of consolidation. This will allow an enterprise to converge its traditional phone system and newer data network for greater efficiency. Arieh Dranger, president of neXTel Systems LLC says, â€Å"I don’t think it’s a question of whether we need VoIP, but when it will come together, because it represents a natural progress o f integrating data- period. The IP protocol is probably the most efficient at combining a universal communications network.† Basically, IP telephony is taking the telecom world by storm. It has evolved from a little known and used application in 1995 to an application that is poised for global adoption. But as with all technology, there is a price to be paid, and several entities vying for a piece of the pie. WHAT IS VoIP and HOW DOES IT WORK? To put it simply, VoIP means Voice over Internet Protocol. It’s a technology that allows network managers to route phone call over the network they use for data transmission. A voice travels over a corporate Intranet or the Internet instead of the public telephone system. Special gateways installed at both the sending and receiving end of a communications channel converts voice to IP packets and back again to voice.

These are the very best guides available on boosting your SAT score, section by section. They're written by Harvard grads and perfect SAT scorers. Don't disappoint yourself - read these guides and improve your score today. Step 1: Identify Challenges Before you get started with astudent you need to make sure you're genuinely going to be able to help your student and determineif there will beany special challenges you'll face. Make Sure You're Qualified Don’t assume that because you’re older than your student, you automatically know more about the test than she does. You probably took the SAT at least five years ago, while she took it a few months ago. If you want to be an effective tutor, you'll have to take the time to really understand the SAT (see the next stepfor more on how to do so). Think of it this way: you won’t be able to explain why an answer is wrong to your student if you don’t understand it yourself. Worse, you won’t be able to figure out why your student is missing the question in the first place. A good rule of thumb is that you should be scoring at least 4 points higher than your student. If she's already high-scoring you’ll want to be at or near perfect. Motivating Your Student One of the biggest challenges of tutoring is convincing your student to put in the work needed to improve. The single biggest key to raising standardized test scores is practice. Part of your job is convincing your student toput in the work to raiseher score. If your student is strugglingto motivate, try discussingthe tangible benefits of a higher SAT score withher. Motivating your student can be especially challenging if you’re working with a family member or friend. This kind of tutoring generally works best when the student is still quite young or is independently motivated and simply coming to you for extra help. Step 2: Study the Test As I mentioned above, in order to be a helpful tutor, you have to know the material you're tutoring: that means learning as much as you can about the SAT. Learnthe Format Though it may not seem important, you should start by making sure that you understand the basics of the SAT: how long it is, how many questions it has, and what the different sections are. Keep in mind that the SAT has changed quite a bit over the past decade, so even if you think you know it well from taking it in high school, make sure to review the current version of the test. It’s important to know exactlywhat your student can expect tosee on the SAT. You need to have a solid grasp onboth the different question formats and the material covered by the test - check out our guides to what's actually on each section of the test if you have questions. Reading Math Writing Understand the SAT's Unique Logic The SAT is very different from the kinds of tests students take in their classes. You’ll need to help your student understand these differences and how to use them to her advantage. First of all, remember that the SAT is overwhelmingly a multiple-choice test: it doesn’t matter how your student gets the right answer, just that shedoes. There are a lot of helpful strategies and shortcuts that can help students get to the answer more quickly. Another key point to remember is that SAT questions often include traps meant to trip up the test taker. Work with your student to help her practice reading questions carefully and resisting makingassumptions about what shethinks a question should be asking. Finally, never forget that the SAT is standardized: no matter how there is only ever one right answer and it is indisputably correct. Make sure you can explain not just why an answer is correct but why the other choices are wrong. Before you can be an effective teacher, you have to study up on the material yourself. Step 3: Set Goals Once you feel prepared, it's time to get started with your student, which means you need to establish exactly what she's hoping to get out of tutoring. You'll need to ask her about her personal aimsand the schools she's considering applying to so you can help her determine an appropriate score goal. Determining a Score Goal It’s easy to assume that you just want to get your student’s score as high as possible, but it’s better to have a specific score in mind. Not every student needs a 2400, and setting an achievablegoalgives your student something concrete to work toward. What the goalscore is will depend on what grade your student is in and what schools or programs she wants to apply to. Assuming your student is a junior or senior applying to colleges, you can use our method, which is based on the SAT scores colleges expect from applicants, to calculate a target. Narrowing Your Focus (If Necessary) Keep in mindthat your student mayneed to focus specifically on raising her score on one or two sections. A particularly low score on one section (especially math or reading) can count against an application, and some schools and programs have a cut off score for certain sections. Another consideration iswhether schools superscore, i.e. count only the highest score on each section.If your student is only applying to schools that superscore and already has a solid score on one of the sections, she may want to focus primarily on the others. Step 4: Gather Great Resources Before you get started with tutoring, you need to make sure you have high-quality practice materials to use with your student.When practice questionshave errors or look nothing like the the questions on the actual SAT, students end up confused or frustrated and, even worse, lose some of their trust in you. Let's go through where you can find some of the most helpful resources for the SAT. Official Tests The best practice materials are official ones, since practicing with real tests will give your student the best idea of what to expect on test day. You want to find and use as many of these as possible. Free practice test and questions for the newest version of the SAT Free old official practice tests (If you want paper copies of the free official practice tests) The Official SAT Study Guide, currently $21.00on Amazon General Strategies Practicing with real SATs is the best way to learn the format and logic of the test, but your student may still need some extra help with strategies for the most effective ways to approach the different types of questions. The following resources can help you find the most effective strategiesfor your student to take. SAT Prep Black Book, Second Edition by Mike Barrett and Patrick Barrett PrepScholar's Ultimate SAT StudyGuide 21 Top SAT Tips Alternative practice materials Subject-Specific Materials Another vitalpart of studying for the SAT is reviewing the content it tests.

Download this free SAT guide now: Step 5: Lay Out a Plan As a tutor, one of your most important roles is making sure your student stays on track. Let's go over some ways you can help your student meet her goals by her test date. Set a Schedule It’s vital that you have a set schedule for tutoring. Without one, it’s easy for students to procrastinate and fall behind. Start by determining when your student will take the test and then plan out how you’re going to cover everything between now and then. Generally speaking, students should shoot for roughly 40 hours of prep, although that timewill be split between tutoring and independent work. Try to set a specific time for your lesson each week. I prefer to meet with students once a week, but if you're on a tight schedule you can certainly do twice a week. With more than two lessons per week, most students will quickly get burned out and frustrated. Analyze Weaknesses Before you start, spend some time determining what your student needs the most help with. If she’s taken the test before, take a look at her scores. Then, if possible, have her take a full practice test before you get started. Going over it together will help you see why she's missing questions and allow you to focus your efforts on the strategies and content review that will be most helpful for her. From there you can plan out what order you’ll cover the material in. I usually start with a student’s weakest areas and then work through everything until I get to her strongest, revisiting the early concepts occasionally to review. Give Homework As I mentioned above, practice is key to improvement on the SAT. You’ll need to give your student practice questions to do or content to review between lessons. Ideally, you’ll also want to have them complete at least three full officialpractice SATs that simulate actual testing conditions. If you’re a parent or sibling rather than a professional tutor, you probably won't be able to convince your student to do extra homework. Instead, try setting aside an extra time during the week for them to study on their own. Good advice! Step 6: Teach the Big Picture When students sign up for tutoring, they often expect to learn tricks that help them instantly raise their scores. There aren’t really any such simple tricks, but there are helpful strategies that, when used consistently, can make a big difference in students’ scores. You may also need to provide content review for your student, depending on their strengths and weaknesses. The following resources offer ideas for specific strategies you can use with your student (most of which are also included in the more overall guides from the previous section). Reading How to read SAT Readingpassages:This guide explains the reading passageapproachthat we recommend for most students- have your student try it and then tweak the approach as needed. How not to run out of time on SAT Reading: Timing can be a big struggle on SAT reading. This guide will give you ideas on how to help your student pace herself. #1 secret of SAT Reading: The SAT Reading often seems more complicated than it is. This guide will help you and your student understand the logic of the test. Math 21 must-know formulas: Although the SAT provides test takers with some basic geometry formulas, there are other formulas your studentwill need to know. How not to run out of time on SAT Math: For advice on how to help your student get through all the question on the math sections efficiently, check out this guide. How to plug in answers:Make sure your student understands the most efficient way to plug-and-chug, especially if she struggles with solving algebra questions quickly. How to plug in numbers: This strategy will help your student approach questions that ask about abstract variables and unknown quantities. Writing Secret to SAT Writing: The SAT Writing section has its own unique quirks. Make sure you understand them so you can help your student adjust her approach accordingly. How to approach SAT Writing passages: All of the SAT writing questions are presented in context. That means your student needs a strategy for tackling the passages! Step 7: Analyze Mistakes SAT questions follow certain patterns, and the best way to get a feel for the style of the questions is to do a lot of practice. As such, regularly practicing with real SAT questions is one of the most important part of studying for the test, and as a tutor you shouldassign a lot of official practice questions. However, it's not enough to simply give some practice passages to your student, you also need to carefully reviewthe questionsshe misses. Don’t stop at saying, "B is the right answer"- really dig in and help your student understand why shegot the question wrong and how shecan avoid missing similar ones in the future. This process is key to helping your student improve and why it's so important that you understand the test yourself. For more details on how to effectively go over missed questions, take a look at our guide to reviewing mistakes. (Bro. Jeffrey Pioquinto, SJ/Flickr) Review: 3 Key Tutoring Tips The steps above offer a general outline to becoming an effective tutor: what exactly you cover and how you work on it will depend a lot on you and your student. Nonetheless,there are a few big picture ideas that every tutor should keep in mind. Be Prepared Your student will know if you’re not invested in the tutoring process: don't try tobluff your way through with a vaguerecollection of taking the SAT in high school - it won't work. Take the time to familiarize yourself with the test and work up an individualized improvement plan for your student. The more you know about the test the better you'll be able to understand your student's unique needs and the more effective you'll be as a tutor. Focus on Motivation Students who don't put in the work don't improve - it's as simple as that. As such, a big part of your role as a tutor is to set expectationsand encourageyour student to study and practice.In some cases, motivating your studentwill be simple(I've had students who actually requested extra homework), but in others you will need to really emphasizewhy the practice is important and how it will help your student reach her goals. Remember that the SAT Is a Standardized Test Always keep in mind that the SAT tests the same simple rules over and over again, just in slightly different ways. Really knowing the test will be your greatest asset as a tutor. Even if you're just starting out, and aren't that familiarwith the test yet,you can use the fact that the SATis standardized to your advantage. Go over official tests carefully and look for patterns in the questions. Remember that because the test is standardized there is only ever one indisputably correct answer. Help your student understand both what will and whatwon't be covered by the test. Bonus: Want to get a perfect SAT score? Read our famous guide on how to score a perfect 1600 on the SAT.

Biological Versus Non Biological Parents Essay Example | Topics and Well Written Essays - 3000 words

Biological Versus Non Biological Parents - Essay Example Miserably, sometimes when a lesbian-parent household falls apart same as normal parents, the biological parent uses the homophobic lawful system to her benefit, denying visitation to the non-biological parent. A case at present in progress in New York is investigating protection procedures that at present support the biological mother. The non-biological mother has been approved temporary visitation for four hours every week until the court makes its concluding decision. Until this provisional agreement was approved just lately, the non-biological mom had not seen her children since November 2005. According to Monroe Mann from ABC News, the lawyer for the biological mother was referenced as saying, "The law in New York is very obvious. Simply a parent can get visitation. A parent is explained as either the biological or adoptive parent and [her ex-partner] is even not." Obviously, biological parents are being better then of non-biological parents, but all courts should have to be familiar with the significance of family unity, and regularly have to consider a biological father's privileges next to a child's right to have the family the child has at all times identified. The courts have routinely held that biology is not the one and only decisive factor of paternity. This is an unexpected pace that the majority of men would not take in spite of the amount of care they are offering to their kids. The court will encounter the issues regarding who has held themselves out to be the father of the child, provided support for the infant and been vigorous in the child's living. While there have been a number of victories for non-biological parents, principles differ from state to state. Last spring in 2005, for instance, the New Jersey Supreme Court settled supervision rights to a non-biological mother, stating her "psychological" parent. This occurred, though, only after a long-lasting lawful procedure. Many activists have worked to demonstrate broader society that even if laws do not value families, they will. Honoring this commitment is put to the eventual analysis when same-sex parents disintegrate. These activists give reason for the want for a document in opening that give details: "It is enormously damaging to our society and our families when we disclaim as unimportant the very relationships for which we are looking for lawful and communal admiration." Planning a guardianship agreement in the happening of a disintegration is about as fun as writing a will. But alike to having a will, such a text offers calmness. The judgments, made at a time when feelings and commonsensical are unbroken, will be conclusions based on the unsurpassed interest of the children, even if the improbable happens. Professional Problem, Concerns And Legal Rights For Non-Biological Parents According to common perceptive, adoption is the officially permitted way for non-biological parents to suppose a parent-child relationship with a child. Adoption frequently ends the

An Analysis of the Epic Poem, Beowulf - The Character of Beowulf :: Epic Beowulf essays

The Character of Beowulf When he arrived at the Danish land, Beowulf was a young man seeking adventure and glory. Beowulf was distinguished among his people, the Geats, for his bravery. As a young man Beowulf fought in many battles and as a result showed his great character to others. Beowulf had many characteristics which helped him to succeed in battle. As a young man, Beowulf was known as the strongest man alive. His strength allowed him to dominate in battle. If it were not for his pure strength, he would not have been able to defeat Grendel, for weapons would not work. By fighting Grendel without weapons, he opened himself up to greater glorification. Beowulf's strength could not be seen as a disadvantage, while the results of his strength could. Beowulf's strength allowed him dominance in battle, but it also made him cocky. While his cockiness allowed Beowulf to be sure of himself in battle, some of his peers found it to be a character flaw. Ecglaf, in particular, saw Beowulf as cocky and vain, questioning, "Are you the Beowulf who competed with Breca...swollen with vanity..." So, while his cockiness was a flaw in the eyes of others, Beowulf saw it as self assurance and used it to his advantage. Beowulf also had a strong spirit of adventure. His spirit of adventure was part of the reason that Beowulf went to fight Grendel. Beowulf's strength and spirit of adventure had also led him to glory in many battles, including that with Grendel. Beowulf used his glory in previous battles to justify himself when coming to help Hrothgar. In addition, his self assurance, and known bravery probably guided his decision. Beowulf's spirit of adventure gained him a lot of glory, however, it could have gotten him into trouble, if he were to have taken an adventure too far. While in his young age, Beowulf used his strength for glory and recognition. As he became older his great strength was taken away from him, and Beowulf found himself without one of his greatest abilities. Beowulf then was king of the Geats, and when a dragon attacked his land, it was his responsibility to protect his people.

Nature Imagery in Othello

Nature imagery in Othello There are quite a few imageries about nature in the book written by William Shakespeare named Othello, were the two male leads named Iago and Othello are the ones who use them the most, Iago talks about how people are gardens also how easy it is to manipulate other peoples garden and he also uses poisonous plants to explain how much harm he has done, while Othello talks about how flowers represent his wife and how they die once they are plucked just like his lover for her.Iago in one of his most famous speeches in the book while having a conversation with Roderigo â€Å"Our bodies are our gardens, to the which our wills are gardeners: so that if we will plant nettles, or sow lettuce [†¦] either to have it sterile with idleness, or manured with industry, why, the power and corrigible authority of this lies in our wills. † He uses imagery to explain that people and he are gardens, the things we do and think are what we plant in it, it also takes ti me to take care of it you need to have patience and plant everything, people can manipulate it and it’s up to us to take care of it.He also says this during another conversation with Roderigo â€Å"Though other things grow fair against the sun, / Yet fruits that blossom first will first be ripe† which goes back to referring to his garden, that even after he plants multiple things the first thing he plants will always come first, which refers to Othello and the revenge Iago wants from him after taking the spot he has been working on since he started and he just came in and snatched it from him. The last imagery used by Iago says â€Å"The Moor already changes with my poison. Dangerous conceits are in their natures poisons, / . . . / . . . Not poppy nor mandragora / Nor all the drowsy syrups of the world / Shall ever medicine thee to that sweet sleep† He is saying that he has corrupted Othello so much that not even poppy or mandragora/mandrake, mandrake was used t o cleanse the body, could heal him from all the corruption he has put in Othello. â€Å"O thou weed,/ Who art so lovely fair and smell’st so sweet/ That the sense aches at thee, would thou hadst ne'er been born! Othello compares Desdemona with a weed since he has been deceived by Iago making him think that Desdemona cheated on him with Cassio and since he thinks this way about Desdemona now he decided to compare her to a weed that is so beautiful when in reality it’s the opposite and know that Othello knows the â€Å"real† Desdemona she will now wish she was never born since Othello is going to get revenge from all the â€Å"wrongs† she did to him.On the last scene where Othello kills Desdemona he comes to her chamber and sees her sleeping, he tells her â€Å"When I have plucked thy rose/ I cannot give it vital growth again,/ It must needs wither† What Othello means is that after he kills her there is no going back, he uses a rose that once that r ose is plucked it starts to slowly die and there is no way for the rose to stop from dying which is what is happening here.This can also signify the love that he has lost for Desdemona since she cheated on him with Cassio, when Othello plucked Desdemona’s love from his heart and it can never grow back again, since he doesn’t want for her to do this again he decides to kill her just like a flower will die from being plucked.The night that Desdemona was going to be murdered by Othello she sang the willow song â€Å"The poor soul sat sighing by a sycamore tree, Sing all a green willow: Her hand on her bosom, her head on her knee, Sing willow, willow, willow: The fresh streams ran by her, and murmur'd her moans; Sing willow, willow, willow; Her salt tears fell from her, and soften'd the stones; Lay by these:– Sing willow, willow, willow; Prithee, hie thee; he'll come anon:– Sing all a green willow must be my garland. Let nobody blame him; his scorn approve,- Nay, that's not next. -Hark! who is't that knocks? † Willow trees are often associated with mourning and grief, which is why they are often called weeping willow, which fits perfectly to what Desdemona is feeling. Desdemona singing this song reflects how she is feeling about Othello, even though she is being accused for something that isn’t true she doesn’t say that he is wrong, even when she knows that he is, she goes along with what he says because she loves him so much, even though it hurts her to be thought like that by the love of her life.When I first read the book Othello, I didn’t pay attention to the references about nature that William Shakespeare used in this particular text, after reading it and getting this assignment I decided to go back and re-read it on my own. After reading the book I noticed that the main characters used plants to explain what they were feeling or going through, for someone to be able to understand and catch on to all of this one needed to be very oriented in nature.

Willis Carrier and the Invention of Air Conditioning

I fish only for edible fish, and hunt only for edible game, even in the laboratory, Willis Haviland Carrier once said about being practical. In 1902, only one year after Willis  Carrier graduated from Cornell University with a Masters in  Engineering,  his first air conditioning unit was in operation. This made one Brooklyn printing plant owner very happy. Fluctuations in heat and humidity in his plant kept causing the dimensions of his printing paper to alter and create misalignment of the colored inks. The new air conditioning machine created a stable environment and, as a result, aligned four-color printing became possible – all thanks to Carrier, a new employee at the Buffalo Forge Company who started working for a salary of only $10 a week. The â€Å"Apparatus for Treating Air† The â€Å"Apparatus for Treating Air† was the first of several patents awarded to Willis Carrier in 1906. Although he’s recognized as the â€Å"father of air conditioning,† the term â€Å"air conditioning† actually originated with textile engineer Stuart H. Cramer. Cramer used the phrase â€Å"air conditioning† in a 1906 patent claim he  filed for a device that added water vapor to the air in textile plants to condition the yarn. Carrier disclosed his basic Rational Psychrometric Formulae to the American Society of Mechanical Engineers in 1911. The formula still stands today as the basis in all fundamental calculations for the air conditioning industry. Carrier said he received his â€Å"flash of genius† while he was waiting for a train on a foggy night. He was thinking about the problem of temperature and humidity control and by the time the train arrived, he said he had an understanding of the relationship between temperature, humidity and dew point. The Carrier Engineering Corporation Industries flourished with this new ability to control the temperature and humidity levels during and after production. Film, tobacco, processed meats, medical capsules, textiles and other products gained significant improvements as a result. Willis Carrier  and six other engineers formed the Carrier Engineering Corporation in 1915 with starting capital of $35,000. In 1995, sales topped $5 billion. The company was dedicated to improving air conditioning technology. The Centrifugal Refrigeration Machine Carrier patented the centrifugal refrigeration machine in 1921. This centrifugal chiller was the first practical method for  air conditioning large spaces. Previous refrigeration machines used reciprocating piston-driven compressors to pump refrigerant through the system, which was often toxic and flammable ammonia. Carrier designed a centrifugal compressor similar to the centrifugal turning blades of a water pump. The result was a safer and more efficient chiller. Consumer Comfort Cooling for human comfort rather than industrial need began in 1924 when three Carrier centrifugal chillers were installed in the J.L. Hudson Department Store in Detroit, Michigan. Shoppers flocked to the â€Å"air  conditioned† store. This boom in human cooling spread from department stores to the movie theaters, most notably the Rivoli Theater in New York whose summer film business skyrocketed when it heavily advertised cool comfort. Demand increased for smaller units and the Carrier Company obliged. Residential Air Conditioners Willis Carrier developed the first residential â€Å"Weathermaker† in 1928, an air conditioner for private home use. The Great Depression and  World War II slowed the non-industrial use of air conditioning, but consumer sales rebounded after the war. The rest is cool and comfortable history.
