Dynamic Analysis of Posture Profiles in Quiet Stance on Carpets through Fractional Brownian Motion

In this study we examine the dynamic characteristics of the center of pressure (COP) profiles in quiet stance on various carpets through the framework of fractional Brownian motion. Four different carpets plus the force platform (which served as a control floor) were tested. Six healthy young subjects stood stationary in bare feet on each..

Prediction of Mechanical Properties of 3-D Braided Composite using CAD system

The geometrical and mechanical properties of three-dimensionally braided glass/epoxy composite were investigated using the CAD system. The three-dimensional (3-D) yarn path was described using third order spline curves referring to our previous work about the circular braided preform. The CAD system for the flat plate-shaped composite was..

Efficiency of Vacuuming for the Removal of Cat Allergen (Fel d 1) from Worn and Unworn Wool Carpets of Different Construction

Exposure to cat allergen (Fel d 1) has been associated with immune responses and exacerbation of asthma. As such allergen can accumulate in carpet, we sought to determine the influence of carpet pile conformation (loop vs. cut) and degree of wear on the levels of Fel d 1 present before and after different cleaning processes. Tufted wool c..
