Samir N.. Gerges - Federal University of Santa Catarina (UFSC)
The Laboratory of Noise and Vibration at the Federal University of Santa Catarina (UFSC) in Brazil is involved in various projects including R&D assistance to the automobile industry to adapt its products to noise and vibration standards. In addition to helping local industries, this supports academic developments in teaching and research for undergraduate and postgraduate students.
Pass-by noise tests are standardized to quantify the maximum sideline noise level during vehicle operation. The test is regulated in most countries with specific sound limits defined by relevant government agencies, typically ISO 362 – measurement of noise emitted by accelerating road vehicles. The specifications are intended to reproduce the level of noise generated by the principal noise sources during normal driving in urban traffic, typically on roads with speed limits of 50 km/h and 70 km/h. The vehicle pass-by noise test certifies that a car complies with the standard so its contribution to traffic noise is not above the permitted limit.
Many elements contribute to the total noise of a vehicle, such as the motor, exhaust, transmission, and tires. Because standard pass-by noise tests do not have the capacity to identify the sources emitting noise that leads to test failure, we needed technique a to visualize the acoustic field to identify these sources. By applying beamforming in this test, we can see which of these sources significantly contributes to the overall noise emission and has an impact on the vehicle’s pass-by noise.

Bill has a business of buying and selling old cars. They found the Martindale school-house and fell in love with is. It was forsale and they wanted to buy it. It was for sale and they wanted to buy it. Some Martindale residents were worried that they would buy their beloved schoolhouse, but the Hamiltons say the feel like its doorkeeper and love the old school.At last they bought it, They built a garden and a swimming pool behind the house. They built two kitchens, three bathrooms, four toilets, four drawing- rooms and eight bedrooms inside it. They even had a dancing-hall in the central part of the house. They repaired the playground as well. They made the old schoolhouse into their comfortable home. Most important, the schoolhouse looks almost the same it was before.Small-town life, especially living in an old school , might seem an unusual choice for the Hamltons. She works for a company and he recently retired. Before coming to Martindale, they enjoyed the good life in their beautiful, four-bedroom home in the city.So they started their new country life. Barri Hamilton says she and her husband have made many friends in Martindale. She didn’t make so many friends though she had lived in Houston for 30 years.Still, the Hamiltons care about their newcomer status. Barri says that, for some residents, buying the school was a “sensitive thing”, since so many had educated there, “it’s important that Bill and I explain to everybody that we fell like doorkeeper of this school, and that we’ll leave it in better shape when we are gone than when we found it.”1、Bill and Barri are _________.A、friendsB、a coupleC、business partners（伙伴）江苏开放大学大学英语（A）（专）形成性考核2 第 5 页D、visitors2、The Hamiltons drove to the small town__________.A、for an outingB、on business tripC、to buy a houseD、to make friends3、Some Martindale residents were worried that the Hamiltons would buy their beloved schoolhouse, but the Hamitions say they .A、feel like taking care of the houseB、want to take the house awayC、want to buy the houseD、want to sell the house4、After they have repaired the old school, it looks .A、just the same as it was beforeB、quite different as it was beforeC、more beautiful than it was beforeD、a bit smaller than it was before5、Barri Hamilton ______________.A、works for a companyB、works at a schoolC、recently retiredD、works as a housewifePassage twoTom was tired of living in his old house in the country and wanted to sell it and buy a better one.

There are times when most of us would rather eat sweets and ice cream than meat and rice. Sweets and ice cream are not bad for the stomach if we .eat them at the end of a meal. If we eat them before a meal, they may take away our appetite (胃口). It is important for us to eat our meal at the same time each day. When we feel hungry, it is a sign that our bodies need food. When we feel angry or excited, we may not want to eat. When we are worried, we may not want to eat, either. A long time ago; in England, some judges used to decide whether a man was telling the truth by giving him some dry bread. If the man could not swallow the bread, it was a sign that he wasn't telling the truth. He was telling a lie. Although this seems very strange and rather foolish, it is indeed an excellent way of finding out the truth. A man who is worrying about something has difficulty in swallowing anything dry. Because when he is worrying, he loses his appetite and does not want to eat.11. We have to develop good eating habits because .A. we want to eat moreB. we want to enjoy our mealsC. we want to be healthy and strongD. we want to save time12. may take away our appetite before we have our meal.A. Either meat or riceB. Neither sweets nor ice-creamC. Not only meat but also riceD. Both sweets and ice-cream13. We had better have our meals .A. when our work is overB. at the same time each dayC. when the meal is still hotD. when we go back home14. A man who is angry has .A. a better appetiteB. a poor appetiteC. to eat more foodD. to eat dry bread15. The judges in old England considered that a man could if he told a lie.A. swallow dry bread easilyB. eat a lot of dry breadC. drink milk or hot waterD. hardly swallow dry breadIV.
