Conventional education results in unsatisfactory morphological understanding of acetabular fractures due to lack of three-dimensional (3D) details and tactile feedback of real fractures. Virtual reality (VR) and 3D printing (3DP) techniques are widely applied in teaching. The purpose of this study was to identify the effect of physical model (PM), VR and 3DP models in education of morphological...

Yoshihiro Sukegawa Kazuhiro Oryoji Eiji Ishii, Dr. Eng. OVERVIEW: Improving the fuel economy and emissions of vehicle engines requires a detailed understanding of the various physical processes taking place inside the engine so as to identify optimal combustion control techniques and engine component designs. Based on numerical techniques established by its power plant business for the analysis...

this paper presents the kinematic analysis and the development of a 4-degree-of-freedom serial-parallel mechanism for large commercial vehicle driving simulators. the degrees of freedom are selected according to the target maneuvers and the structure of human motion perception organs. several kinematic properties of parallel part of the mechanism under study are investigated, including the inve...

OBJECTIVE Examine after-school activity patterns, eating behaviors, and social environment of overweight and normal weight middle school students. DESIGN Eating and physical activity behaviors of 141 students, ages 10-14, were monitored. Students completed a diary documenting type of activity, location, adult supervision, accompanying participants, and eating habits from 3:00 pm-12:00 am. S...

We present a stochastic computational model to study the mechanism of signaling between a source and a target ionic transporter, both localized on the plasma membrane (PM). In general this requires a nanometer-scale cytoplasmic space, or nanodomain, between the PM and a peripheral organelle to reflect ions back towards the PM. Specifically we investigate the coupling between Na(+) entry via the...

In order to perform Preventive Maintenance (PM), two approaches have evolved in the literature. The traditional approach is based on the use of statistical and reliability analysis of equipment failure. Under statistical-reliability (S-R)-based PM, the objective of achieving the minimum total cost is pursued by establishing fixed PM intervals, which are statistically optimal, at which to replac...
