Abstract A strong issue on the development of new vehicles is the weight reduction, required for the reduction of the fuel consumption and the CO2 emissions. The current vehicles have already a structure optimised to have low weight without reducing the required performances.

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. All too often, noise and vibration are ignored until well into the design phase, at which point incorporation of the most cost-effective solutions may not be possible. Successful noise and vibration control require consideration of both the track and the vehicle as a system, because the interaction of the wheel and the rail is responsible for the bulk of wayside noise and vibration impacts. This chapter attempts to summarize the main issues and theories related to noise and vibration production and control and the related issues concerning rail wear, identify areas where insufficient knowledge exists, and provide guidance with respect to track design for acceptable levels of noise and vibration. While many of the treatments considered here can be selected and designed by the transit track engineer, the design of some provisions, such as floating slabs or vibration absorbers, should be conducted by those who have considerable experience with designing and specifying vibration isolation systems, have an engineering or physics background, and understand the principles of noise and vibration control.

It was approved as an incorporated body of Environmental Agency of Japan the present Ministry of the Environment in Fundamental training courses and technical workshops are periodically planned every year, whereas other lecture meetings or symposia are also planned whenever necessary. Lecturers documents are available here. Power Point files of the three lectures have been uploaded with summary and reference papers on the WEB Site by courtesy of the authors. Please feel free to download those on condition you refer to the originality of the lecturers when using those in other papers or presentations. Anyone interested in noise and vibration control shall be eligible for Members of the Institute.

It seems that you're in Germany. We have a dedicated site for Germany. It is one of the author's most important goals not only to describe how the topic develops but also why a specific way is chosen. The explanations do not restrict themselves to mathematical formulas. Only the illustrative explanation relying on the reader's imagination creates comprehension. This book presents the foundations of that what nowadays seems necessary to make our environment quieter - in buildings as well as in the open air.

 Что ты говоришь? - засмеялся Стратмор.  - Что же ты предлагаешь. Открыть дверь и вызвать сотрудников отдела систем безопасности, я угадал. - Совершенно. Будет очень глупо, если вы этого не сделаете.

Он действительно это сделал. - Да. Создатель последнего шифра, который никто никогда не взломает.

Это наша главная цель. Простое число. Джабба посмотрел на таблицу, что стояла на мониторе, и всплеснул руками. - Здесь около сотни пунктов. Мы не можем вычесть их все одно из другого.

Сирены по-прежнему выли.

 - Он провел рукой по своим коротко стриженным волосам.  - Я кое о чем тебе не рассказал. Иной раз человек в моем положении… - Он замялся, словно принимая трудное решение.

 Вот что я вам скажу, - решительно заявил директор.  - Через пятнадцать минут все страны третьего мира на нашей планете будут знать, как построить межконтинентальную баллистическую ракету.

Кроме всего прочего, Хейл был настоящим ходячим несчастьем, готовым свалиться на голову в любую минуту. Из задумчивости Стратмора вывел звонок мобильного телефона, едва слышный в завывании сирен и свисте пара. Не останавливаясь, он отстегнул телефон от брючного ремня.
