A new approach has been proposed for increasing astronaut comfort and speech capture. Currently, the special design of a spacesuit forms an extreme acoustic environment making it difficult to capture clear speech without compromising comfort. The current system, called Communication-Cap-based Audio (CCA), relies on a single microphone placed close to the subject’s mouth. While this results in c...

The article describes the results of the project "open source smart lamp" aimed at designing and developing a smart object able to manage and control the indoor environmental quality (IEQ) of the built environment. A first version of this smart object, built following a do-it-yourself (DIY) approach using a microcontroller, an integrated temperature and relative humidity sensor, and techniques ...

Received signal strength indicator plays a very important role in many WLAN applications. However wireless signal strength will be greatly affected by noise and disturbance. It is critical to remove the abnormal data in order to provide a reliable estimation of the received signal strength indicator. Conventional mean value based approaches require large amount of data which would lead to unrel...

We investigate strategic information transmission with communication error, or noise. Our main finding is that adding noise can improve welfare. With quadratic preferences and a uniform type distribution, welfare can be raised for almost every bias level by introducing a sufficiently small amount of noise. Furthermore, there exists a level of noise that makes it possible to achieve the best pay...

In the automotive industry, vehicle interior acoustics has become an important design criterion. Both legal restrictions and the growing demand for comfort, force the car manufacturers to optimize the vibro-acoustic behaviour of their products. The tendency to minimise the number of physical prototypes and to reduce the overall development cost and time, as well as the high performance of moder...

In this study, noise and vibration measurements were carried out on a multi-phase 12/8 switched reluctance (SR) motor and analyzed with vibro-acoustic techniques. When evaluating the behavior of electric powertrains for automotive applications, it is necessary to perform a vibro-acoustic analysis, particularly in view of the acoustic comfort perceived by the driver and passengers. High frequenc...
