With the large-scale density stratified tank and numerical flume proposed, series of cases in line with experiments are carried out to investigate interaction between tension leg platforms (TLPs) internal solitary waves (ISWs). The waveforms, loads torques on TLP obtained by simulations agree well each other. Experimental results show that amplitudes dimensionless horizontal force torque linear...

The temporal sequence of mechanoreceptor input arriving at the motoneuron level in the central nervous system (CNS) after distal mechanical contact was studied for the locust middle leg. Different types of afferent information from potential contact areas after selective stimulation showed propagation times of no less than 8 ms from mechanosensory hairs, campaniform sensilla (CS) and spurs of t...

A N−1 wire-driven parallel robot is a robot for which all the N ≥ 3 wires are connected at the same point of the platform, allowing to control the location of this point. We are interested in the positioning accuracy of such a robot. If the wires are not elastic we show that the influence on the accuracy of the co-location errors of the wire anchor points on the platform is moderate, although a...

Any set of two legs in a Gough–Stewart platform sharing an attachment is defined as a ∆component. This component links a point in the platform (base) to a line in the base (platform). Thus, if the two legs, which are involved in a ∆ component, are rearranged without altering the location of the line and the point in their base and platform local reference frames, the singularity locus of the Go...

PURPOSE Recent in vitro research has suggested that anterior cruciate ligament (ACL) reconstruction does not restore control of tibial rotation. The purpose of this study was to explore these findings in vivo and investigate rotational knee stability during landing and subsequent pivoting. Such an activity places higher demands on the knee, almost similar to those found during high-level sports...

Robots that can move over rough terrain with active body leveling are now in strong demand. Such a robot can have a variety of uses, such as carrying packages, assisting people who have difficulty in walking, and safety monitoring outdoors. Many robots capable of moving over rough terrain exist as research tools; however, few are suitable for practical use. These robots can be generally classif...

This study was conducted to determine if VO, of stepping in children is affected by altering the step platform height based on leg length. The effect of leg length on VO, and heart rate (HR) during stepping was examined in 19 children, ages 8-17, who stepped onto 5 different bench heights that corresponded to hip angles of 65", 73", 82", 90°, or 98". VO, and HR response to a work load of 8 m . ...
