A principle objective of human walking is controlling angular motion of the body as a whole to remain upright. The force of the ground on each foot (F) reflects that control, and recent studies show that in the sagittal plane F exhibits a specific coordination between F direction and center-of-pressure (CP) that is conducive to remaining upright. Typical walking involves the CP shifting relativ...

A survey measuring heights and weights of 1969 schoolchildren residing on the Navajo Indian Reservation was conducted in 1989. The findings were compared with National Center for Health Statistics (NCHS) reference data and with surveys of Navajo children from 1955, 1968, and 1981. Approximately twice as many children exceeded the 95th percentile of weight-for-age (1 1 .2% of girls, 1 2.5% of bo...

A power-law scaling relationship describes tsunami runup heights at ten locations in Japan. Knowledge of the scaling law for tsunamis can be the basis for probabilistic forecasting of the size and number of future events and for estimating probabilities of extremely large events. Using tsunami runup data archived by the U.S. National Geophysical Data Center, we study ten locations where the tsu...

Hot ring rolling is a highly nonlinear, unsteady-state and asymmetry process which is affected by many parameters. The friction coefficient between the ring ,the driver roll and the idle roll is one of the problems, which has significant effect on the quality of final product. In this study, the effect of these two parameters on hot ring rolling was investigated based on a 3D coupled-thermo mec...

Rollover is one of the most dangerous events in driving Vehicles, specially the Sport Utility ones. This maneuver is the main reason for the majority of human and financial loss in transportation systems. The upcoming paper outlines the details as well as the plus points of a Fuzzy Logic Controller which is designed and simulated to reduce the rollover propensity of Vehicles, specially the ones...

The effects of the slope ground and obstacle conditions on lateral overturning/backward rollover a tractor with an implement were analyzed through dynamic simulation. implement’s 3D simulation model was constructed. As for conditions, four heights three shapes set obstacles, eight slopes to be traveled by implemented tractor. Under each condition, critical speed at which begins overturn roll ov...

Two types of high-speed twin-roll casters and a single-roll caster equipped with scraper were proposed. One the is vertical-type caster, other an unequal-diameter caster. The can cast strip at speeds up to 120 m/min. casts 60 superior point conveyance strip. A without center-line segregation 40 use copper alloy roll non-use parting material enable casting. Since loads these are smaller than 0.1...
