Falls are unpredictable accidents and resulting injuries can be serious to the elderly. A preventative solution can be the use of vibration stimulus of white noise to improve the sense of balance. In this work, a pair of vibration shoes were developed and controlled by a touch-type switch which can generate mechanical vibration noise to stimulate the(More)
OBJECTIVE To compare the differences between advanced percutaneous vertebroplasty and routine percutaneous vertebroplasty,and evaluate the clinical application of advanced percutaneous vertebroplasty in treating senile osteoporotic vertebral compression fracture. METHODS From January 2010 to January 2011,28 patients with senile osteoporotic vertebral(More)
Electrochemical oxidation degradation of azo dyes has become a widely used method in recent years. Iron phosphomolybdate (FePMo12) was synthesized with molybdophosphoric acid and ferric salt. Morphology and microstructure of catalyst were chararerized by IR spectrometry and X-ray diffraction. The heteropolyanion showed a Keggin structure. Electrochemical(More)
In a distribution channel, channel members are not always self-interested, but altruistic in some conditions. Based on this assumption, this paper adopts a behavior gamemethod to analyze and forecast channel members’ decision behavior based on result fairness preference and reciprocal fairness preference by embedding a fair preference theory in channel(More)
In order to correct non-uniform backgrounds in thermal images of carbon fiber-reinforced polymers (CFRP), we propose a processing and analysis procedure in this paper. We apply thermographic signal reconstruction (TSR) using time-direction information to reduce noise in thermal images, followed by Whittaker smoothing (WS) to further reduce noise in(More)
Resin transfer molding (RTM) is a popular manufacturing technique that produces fiber reinforced polymer (FRP) composites. In this paper, a model-assisted flow front control system is developed based on real-time estimation of permeability/porosity ratio using the information acquired by a visualization system. In the proposed control system, a radial basis(More)
Supported phosphotungstic acid catalysts on gamma-Al2O3 (HPW/gamma-Al2O3) were prepared by solution impregnation and characterized by FTIR, XRD, TG-DTA and SEM. The heteropolyanion shows a Keggin structure. Electro-chemical oxidation of Acid Red 3R was investigated in the presence of HPW supported on gamma-Al2O3 as packing materials in the reactor. The(More)
