SIR—Brooke-Wavell and Mansfield rightly point out that whole body vibration exercise may prove useful for older people who cannot perform conventional exercise [1]. Perhaps its greatest attraction to clinicians is that it involves minimal active movement by the participant, such that it has potential for use in the rehabilitation of very immobile patients who are not improving with more convent...

Supine human response and vibration-suppression during whole-body vibration." MS (Master of Science) thesis, ii ACKNOWLEDGMENTS I would like to acknowledge the U.S. Army Aberdeen Test Center (ATC) for the use of the inertial sensors, the USA Army Research Lab (USAARL) for providing the litter, Dr. David Wilder for providing the long spinal board and cervical collar, Mr. Jonathan DeShaw for assi...

fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). it is well known that the structure and prope...

Although many rail travellers use portable computers while travelling, the train environment has not been influenced by the desire to operate computers. Some trains provide power points and tables for portable computers, but an optimal design also requires understanding of how typing is disturbed by train motion. There are numerous studies of typing in static conditions and many studies of the ...

This paper presents the main findings of a field survey conducted in the United Kingdom into the human response to vibration in residential environments. The main aim of this study was to derive exposure-response relationships for annoyance due to vibration from environmental sources. The sources of vibration considered in this paper are railway and construction activity. Annoyance data were co...

In ultrasonic tube hydroforming, the tube is hydro formed while the ultrasonic vibration is applied to the die. Prior studies provide experimental proof that ultrasonic tube hydroforming reduces corner radius, improves lubrication and uniform thickness. Use of ultrasonic vibration can decrease friction at the tube-die interface. Few attempts have been made to analyze the wire drawing while the ...

Riveting tasks in aircraft manufacturing results in exposure to vibration from both rivet guns and bucking bars. Long term exposure to vibration has been associated with symptoms of vibration white finger and musculoskeletal disorders. Four different bucking bars of the same shape but different material and mass characteristics (90% tungsten, >90% tungsten, cold rolled and stainless steel) were...

Insects use airborne vibrations caused by their own movements to control their behaviors and produce airborne vibrations to communicate with conspecific mates. In this review, I use two examples to introduce how insects use airborne vibrations to accurately control behavior or for communication. The first example is vibration-sensitive sensilla along the wing margin that stabilize wingbeat freq...

The development of the muscle vibration technique in humans provides a new means for studying the role played by muscle afferents in motor control and, furthermore, the technique seems to have diagnostic as well as therapeutic applications. It is now well documented that high frequency mechanical vibration applied to any skeletal muscle in man tends to induce the following reflex response: sust...

In this paper we assess the potential of rich tactile notifications on mobile phones. Many mobile phone users use vibration output for various types of notification on their phone. Currently, tactile output in phones is limited to one single actuator that can potentially present patterns based on different vibration intensities over time. To explore the possible design space, we conducted exper...
