Operator exposure to high levels of whole-body vibration (WBV) presents risks to health and safety and it is reported to worsen or even cause back injuries. Work activities resulting in operator exposure to whole-body vibration have a common onset in off-road work such as farming. Despite the wide variability of agricultural surface profiles, studies have shown that with changing soil profile a...

OBJECTIVE This study investigated the factors that can affect the comfort of patients who underwent diagnostic fiberoptic bronchoscopy (FOB) and diagnostic endobronchial ultrasonography (EBUS) for the first time and the effect of the patients' anxiety level on their comfort during the procedure. MATERIALS AND METHODS We recorded the demographics of the patients, the medications they used prev...

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...

This work aims at presenting the experience of the authors in applying the “product sound quality” approach to the noise signals recorded at the operator station of some earth moving machines (EMMs) in order to improve the acoustic comfort for the operator. For industrial products, the concept of “product sound quality” was defined by Blauert and Jekosch as “...a descriptor of the adequacy of t...

Overall seating comfort is influenced by both static and dynamic characteristics of seat system. Therefore, the present study is an overview of work related to comfort in seat-operator interface affected by static and dynamic pressure distribution, and other related parameters involved in seat comfort, low back pain, seat design and safety in seats. A critical review has been presented on the s...
