Background: Noise and vibration are environmental pollutants that endanger people’s productivity sleep quality in ships, but the coupled effect ship cabins has not been studied. This study aimed to assess of noise propose a comfortable range vibration. Methods: Three different accommodation were chosen measure levels investigate their satisfaction. A revised model combining exponential membersh...

In this paper the state the art methods for Ambient (AVT) and Forced Vibration Testing (FVT) are compared. First two new methods to conduct ambient tests are introduced, which allow sensor roving of one group while measuring another group of sensors. The systems compared were concurrently used during a number of tests aimed at damage detection performed on the bridge Z24 in Switzerland. Some of...

the most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy by the effect of coupling between electric fields and mechanical variables. using piezoelectric cantilevers is the most common method for vibration energy harvesting. changing the shape of the cantilevers can lead to changing the generated output v...

and Applied Analysis 3 island of Taiwan. In this study, the chosen Kaohsiung Luchu science park is one of the major parks located in the southern part of Taiwan. This park has a total area of 571 hectares, which started construction in the year of 2001 and was completed in 2010. Various hightech industries, such as integrated circuits, precision machines, optoelectronic components, computer per...

AbstractTimber floors are prone to exhibit vibration levels, which can cause discomfort the occupants. In last 20??years, ambient tests have become very popular due many adv...

Combining shock and vibration isolation into a single isolation system package is explored through the use of an air spring in parallel with a controlled magnetorheological fluid damper. The benefits of combining shock and vibration isolation into a single package is discussed. Modeling and control issues are investigated and test and simulation results are discussed. It is shown that this hybr...
