Speed Detection of Moving Vehicles Using Doppler Effect

| SPEED DETECTION USING DOPPLER EFFECT AND RADAR | | | INTRODUCTION Although there is good road safety performance the number of people killed and injured on our roads remain unacceptably high. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The road safety strategy includes all forms of invention based on the engineering, education and enforcement and recognizes that there are many different factors that lead to traffic collisions and casualties. The main reason is speed of vehicle. We use traffic lights and other traffic manager to reduce the speed. One among them is speed cameras. Speed cameras on the side of urban and rural roads, usually placed to catch†¦show more content†¦Doppler Effect: the principle of this effect is well known in the study of sound. It is known that if the source of sound, emitting a note of frequency v is move with a constant velocity V relative to an observers, it is found that the observer ‘p’ perceives a sound having the frequency v which differs from v, being greater or smaller according to the source is move towards or away from observers. This phenomenon in sound was first explained by Doppler and hence the name Doppler effect. But Fizeau showed that the same effect on light. Thus if the source of light is moving with a wavelength observed in the Spectroscope slightly different from the original wavelength. The principle of speed camera that is the Dopplers effect can be described by the formula fM = 2vfEcos(ÃŽ ±/c) Where fM if the frequency of the received signal v is the speed of vehicles fE if the frequency of transmitted signal ÃŽ ± is the angle between the transmitted signal and path along which the vehicle travels c is propagation speed of the signal in the air. Figure 1. The Doppler Effect From this we can deduce that sending a fixed frequency signal towards the car and then measuring the efficiency of the returning signal the can the deduce the speed of the car.The principal used for Radar in speed camera, although they have little in commonShow MoreRelatedRadar Of Radio Detection And Multiple Classification And Sub Systems Used For Processing1699 Words   |  7 Pages II.

Scrubs vs Greys Anatomy free essay sample

There have been many different medical TV shows in the years. I have watched many of them because there are enjoyable to me and many other people. The two that I watch the most are actually very different in style but still are very similar in format. Scrubs and Grey’s Anatomy are both about interns and their adventures becoming doctors, however they are different in many ways. For example, Scrubs is a comedy and Grey’s Anatomy is a drama. In this paper, I plan to show you in detail how they compare and contrast. The most obvious reason that these shows are different is the genre of the TV show. Scrubs is a laugh out loud type of comedy, where things that will never in a million years actually happen, happen in this show. Scrubs target audience is going to be different because of this as well; the target is going to be for someone with light humor mainly in my mind for teenagers to thirty-year-old men and women. We will write a custom essay sample on Scrubs vs Greys Anatomy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Many of their jokes are very elaborate and would take more time that an intern would actually have, but it is still funny. Grey’s Anatomy is a completely different genre. It is a drama that depicts much more closely, what actually happens in a hospital, going more into detail on what actually goes on with the patients. They show the more of the sad part of medicine because; it is not followed up with a joke. Because this is not a comedy like Scrubs it allows you to see how hard it is to become a doctor and the stressful lives that they have. This is one of the reasons that I enjoying watching this show, when I want see the hardships that many of Americans live with, I watch Grey’s Anatomy. When I want a good laugh, I tone into Scrubs. This makes the audience much different as well; I think the target audience is 14 and up females. Many men end up watching the show as well because their spouses watches it and they get hooked, that’s what happened to me. I enjoy watching both of these shows for different reasons because they are so different in style. Despite having the same bases for their shows, the creators of Scrubs and Grey’s Anatomy went after a different group of viewers with a very different style. With both shows, there are a group of interns that all started at the same time and they are together the majority of the show. In both shows, they become a good friend that leads them to hang out outside of work. In both of these shows as well they have become friends with other members of the hospital, their bosses, and they also hang out outside of work but Scrubs is the only one that has a member from the maintenance crew, the janitor, join them. This is just another example of how Scrubs does not depict what is really like in a hospital. I worked for the maintenance crew for a hospital just out of high school, stocking the linen closet with clean linens from the basement; I never talked to a doctor or nurse, except my step mom. When these groups of friends hang out they both go to a bar to hang out and forget about the hard job they have to do. Grey’s Anatomy is the only one that becomes friends with the bartender and uses him to talk to and vent when things go bad. The similarities here are those of many careers, and that is going to the bar after work. The bar is a place frequent by many people and many TV shows have it as a major scene. Both of these shows are no different, they both have many scenes that are in a bar. Scrubs and Grey’s Anatomy are both about interns and their adventures becoming doctors, however they are different in many ways. In this paper, I have showed you how Scrubs and Grey’s Anatomy are similar and different from an overall and detailed manor. I enjoy watching this shows even though they are so different and some much the same. I have also noticed that many of the actors that play patients in one show will also play a patient in the other show. I have noticed at least ten different actors that have played a patient on both shows.

Last Game (Narrative) Essays - Baseball Rules, Origins Of Baseball

Last Game (Narrative) To be given the chance to play little league was one of the greatest times of my life. I played little league for four years, and every year I made the all-star team. My best friend and I played on every regular season team and every all-star team together. The final game of our career was unforgettable. It had been 4 years of great enjoyment with my best friend, Cody Smith. We always clowned around in practice, but when the game would start we had a high intensity. Cody would pitch, and I would play second base. When he wasn't pitching, I would, and he would play third base. We were the top players in little league, or so we thought. Our all-star team had made it to the championship of our state tournament. Before our team took the field our coach John Zamouski gave us a talk. He said, ?Well men, we've came a long way. Today's the day we've all practiced so hard for, but I want to have fun with it. Lets treat this like every other game we have won. You're all winners, win or lose. I want you all to know that I feel privileged to have coached such a fine bunch of men. So lets go out and play this game as hard as you can. What do you say, lets go have FUN.? We all got up and yelled, ?YEA.? ?Let's play hard.? ?Yea? As we all got more pumped up. ?Who are we ?N.I.? As we got more loud and more intense. Coach said, ?Bring it in. Win on 3. One, two, three? as we all yelled together ?WIN.? As I ran on to that field I recalled all the practicing I had done, and I knew I owed most of it to my father. He started me throwing and hitting when I was about four-years-old. As my passion grew more and more I wanted to go practice all the time. So I would ask my father to practice with me. Even though my father was tired or in the middle of a good TV show he would practice with me. I remembered my father sitting on an old milk crate while I pitched to him. This made me chuckle a little because I would throw a low wild pitch on accident that would hit him in the legs, but he kept positive. Cody was pitching a 3 hitter and I was playing well too. The score kept going back and forth. There were a lot of errors because the field was all dirt and felt like concrete, the ball was taking bounces I had never seen before. The final inning came around and we were down by 1 run with 2 outs when I came to bat. There was no one on base and the pitcher had 2 strikes on me. The next pitch seemed like it took forever. The pitcher pitched the ball right down the middle of the plate. I waited on the ball and hit a screaming line drive into left-center for a stand up double. Then Cody came up and hit the first pitch for a 2-run homerun for us to take the lead by 1. The next batter grounded out to end the inning, but the damage had already been done. We took the field and Cody was still pitching. The first batter hit a double and then stole to advance to third base. Cody then struck out the next two batters. Their were two outs and a runner on third base. Before Cody pitched that next b all I knew every player on our team told themselves that they would do whatever it took to get that next out. So when the ball was pitched and hit to me I was determined to get the out. The ground ball took a bad bounce and hit me square in the ribs. I picked up the ball, which was to the left of me. I spun around and threw that ball with all my power to first base. The ball reached the first basemen's mitt a half step before the runner made it to the base for the third out

Simple Distillation Lab Report Essays

Simple Distillation Lab Report Essays Simple Distillation Lab Report Paper Simple Distillation Lab Report Paper Essay Topic: Simple Fractional distillation is almost the same as the simple distillation, the only preference is that in a fractional distillation, fractionating column is used which is attached at the top end of the pear-shaped flask and it is connected to the condenser as well. Vacuum distillation is a process used to reduce the pressure to a lower boiling point. In a vacuum distillation, the solvents boiling point should be over OFF or ICC. This distillation method is used to recuperate the solvents higher boiling point. Finish Thompson Inc. ) In a steam distillation process, the main objective is to separate the two components in a temperature that is lower than their decomposition point. Steam distillation is process of separation to separate natural aromatic compounds. In order for the boiling point of the mixture to subside, steam or water is to be put in the distillation apparatus. (Helplessnesss, 201 3) The group performed simple distillation in order to separate the al cohol content of vodka from the solution. The objective of this experiment was to separate the alcohol component in the Vodka (Antonio) and to compute for its percentage of ethanol. MATERIALS AND METHODS A. Materials The materials the group used in this experiment are Vodka (Antonio), boiling tones, alcohol lamp and the quick-fit apparatus which consist of the following: iron stand, iron ring and iron clamp for support, pear-shaped distilling flask, distillation head, thermometer, thermometer adapter, condenser, vacuum adapter and test tubes. B. Methods The very first step in this experiment was to make the simple distillation set-up. The iron clamp attached to the iron stand became the supporting apparatus for the distillation head, which was connected to the pear-shaped flask and another iron clamp attached to the iron stand was supporting the condenser, which a art of the distillation head and the vacuum adapter was connected to. The thermometer was attached at the top end of the distillation head together with the thermometer adapter to see the regulation of the temperature. The group prepared 20 test tubes and it was calibrated to ml, marked the lower meniscus of it using a marker and labeled it accordingly. The group placed at least three boiling chips/stones into the pear-shaped distilling flask and added ml of Vodka (Antonio) inside the said flask. Boiling chips were placed inside the pear- shaped distilling flask in order to avoid bumping of molecules and prevention of avian a contamination. Alcohol lamp was used as the heat source. The group rotated it under the pear-shaped distilling flask in order for the liquid mixture to boil. Each of the calibrated and numbered test tubes, the group collected 0. Ml of distillate and while collecting the distillate, the temperature at which the distillate was collected was recorded.

Words for Extreme Weather Events

Words for Extreme Weather Events Words for Extreme Weather Events Words for Extreme Weather Events By Mark Nichol What’s the difference between a hurricane, a typhoon, and a tropical storm? The first two types of weather events are cyclones that sustain surface winds of at least 74 miles per hour- faster than virtually any highway speed limit in the United States. The term â€Å"tropical storm† refers to a degraded hurricane or typhoon. And why are there separate designations for hurricanes, typhoons, and cyclones, which are essentially identical weather events? Hurricanes are storms that develop east of the International Date Line, which runs north to south through the middle of the Pacific Ocean. Hurricane is derived from the aboriginal Taino language’s word hurakn, which was borrowed into Spanish as huracn and thence into English. Taino was spoken throughout the islands of the Caribbean Sea, so it is natural that the language would inspire present-day usage. (A number of other words survive by assimilation from that dead language into English, including barbecue, hammock, and tobacco.) Typhoon, by contrast, stems from Greek, although it refers primarily to storms occurring in the vicinity of China and the Philippines, on the other side of the International Date Line. What’s the connection? The Greek term typhon was appropriated by the Arabs and thence found its way into Chinese, influenced by a similar-sounding Chinese word for â€Å"big wind.† And cyclone, also from Greek (ultimately from kyklos, also the origin of circle and cycle), is used popularly in the South Pacific Ocean, though scientists worldwide use the term when speaking or writing in English. Why do we capitalize names of hurricanes, typhoons, and tropical storms, and why are they assigned people’s first names? These are conventions established in the early 1950s by the scientific community to distinguish between two or more weather events occurring at or near the same time. (For the first quarter-century, only female names were used, following an alphabetized list. Starting in 1978, male names were used as well.) The tradition of assigning personal names to severe storms actually goes back hundreds of years, however; Caribbean hurricanes were named after saints based on which saint’s day the storm occurred, and the assignment of women’s names dates to the late nineteenth century. Some eighty names have, because of the catastrophic severity of the event, been retired from the list, an average of more than one a year; in 2005, Hurricane Katrina was only one of five storms whose names were retired because of the especially devastating nature of the storm. The score given to quantify a hurricane’s strength is also capitalized; the highest level is Category 5. Todays YouTube video: Inquire vs. Enquire Want to improve your English in five minutes a day?

Effect of Teaching Style on Students Scores Essay

Effect of Teaching Style on Students Scores - Essay Example The results revealed no significant changes between the two groups of students when using the ANOVA but depicted elevated levels in 2009 using the MRT. The PCC test revealed some positive correlation between the sampled assessment test scores. Therefore the study demonstrates that teaching styles are correlated to the final scores among students hence innovative teaching style has a favorable consequence among the learners’. Conventional teaching techniques are increasing being viewed as deficient in terms of upholding extensive scholarship and lasting preservation of essential educational concepts. Additionally, these teaching processes are alleged of encouraging quiescent rather than active interactive scholarship (Meyers & Jones, 1993). The advent of sophisticated ICT learning tools has compelled hitherto conservative educationalists to adopt modern methods of teaching especially in the scientific fields of study of science, mathematics, engineering, and technology educatio n. Considerable research has proven the wisdom of assimilating these innovative techniques, as growth have been demonstrated in the education milieu particularly in adult education (Hein & Irvine, 2004). Kolb (1985) in his pragmatic learning cycle claimed that a learner undergoes various stages of knowledge sequence; whereby there is a certain foremost useful stage that is conducive to instruction and understanding. DePorter (1992) further observed that perceived disparities in a student learning style are often caused by ‘a conflict.
