This paper presents results from a large scale study investigating the human response to vibration in residential environments. The main aim of this study was to derive exposure-response relationships for annoyance caused by vibration experienced within residential properties from sources outside of residents‘ control. The study took the form of a questionnaire administered to UK residents in t...

abstract: in this paper, nonlocal euler–bernoulli beam theory is employed for transverse vibration analysis of an initially pre-stressed size-dependent rotating nanotube. the nonlocal eringen theory takes into account the effect of small size, which enables the present model to become effective in the analysis and design of nanosensors and nanoactuators. governing equations are derived through ...

The European Union adopted a Directive in 2002 on minimum requirements for the health and safety of workers exposed to vibration. This is known as the Physical Agents (Vibration) Directive. It builds on existing general employers' duties to manage risks to health and safety, and introduces exposure action and limit values for both hand-arm vibration and whole-body vibration, setting minimum sta...

Anyone seeking to control the risks from vibration transmitted to the hands and arms may contemplate the use of anti-vibration gloves. To make an informed decision about any type of personal protective equipment, it is necessary to have performance data that allow the degree of protection to be estimated. The information provided with an anti-vibration glove may not be easy to understand withou...

Continuously monitoring the operation of each individual fan can significantly improve the measurement quality of aerial pollutant emissions from animal buildings that have a large number of fans. To monitor the fan operation by detecting the fan vibration is a relatively new technique. A low-cost electronic vibration sensor was developed and commercialized. However, its large scale application...

BACKGROUND Tissue healing is an intricate process that is regulated by circulation. Heat modalities have been shown to improve skin circulation. Recent research supports that passive vibration increases circulation without risk of burns. Study purpose is to compare and determine effects of short duration vibration, moist heat, and a combination of the two on skin blood flow (SBF) and skin tempe...

Stewart platform is a good candidate for high speed and six degree of freedom motion control, finding its application in the area of multi-axis vibration control. The critical problems associated with Stewart platform are the high non-linearity and uncertainty in its dynamics. To model the system dynamics of the Stewart platform a simple linear model is developed, for the motion of the Stewart ...

Regular whole body vibration training, i.e. standing on a platform that vibrates at a high frequency over a small amplitude, has been reported to produce neuromuscular adaptation and increase bone mineral density in some frailer populations [1]. As such, it has attracted interest for its potential benefits regarding physical function, fall and fracture risk in older people. These potential bene...

OBJECTIVES To investigate changes in digital circulation during and after exposure to hand transmitted vibration. By studying two frequencies and two magnitudes of vibration, to investigate the extent to which haemodynamic changes depend on the vibration frequency, the vibration acceleration, and the vibration velocity. METHODS Finger skin temperature (FST), finger blood flow (FBF), and finge...
