In this study, it is experimentally investigated that the surface generation process in the cross axis grinding method with small diameter grinding wheel. In this grinding method, workpiece surface speed and sum of both wheel working surface speed and wheel feed rate crossed each other. Therefore, it is the largest characteristic that the cross angle, which is defined as the angle between the w...

This paper outlines the historical development of the wheel and rail profiles currently used on railway vehicles. It also presents the key damage mechanisms involved in wheel-rail contact and summarises the methods that have recently been developed by railway engineers to predict the level of wheel and rail damage from these mechanisms. Tools for predicting the key damage modes of wear and roll...

The authors investigated the effect of the opioid antagonist naloxone on wheel-running behavior in Balb/c mice. Naloxone delayed the acquisition of wheel-running behavior, but did not reduce the expression of this behavior once acquired. Delayed acquisition was not likely a result of reduced locomotor activity, as naloxone-treated mice did not exhibit reduced wheel running after the behavior wa...

A Rover’s wheel performance is one of the limiting factors in its ability to successfully traverse other planets. More research focusing on wheel materials, design, and optimized tread patterns needs to be conducted so that a rover can reach more of its potential. A wheel test bed is being fabricated to test new wheel designs and to collect data which will be used to map the relationship betwee...

This paper illustrates the use of the envelope theorem for the geometric design of a cycloidal speed reducer. Specifically, it proposes two designs for a mathematical model with tooth differences: a pin wheel epitrochoid meshing which is a cycloidal wheel (internal rotor) profile equidistant to an epitrochoid (or extended epicycloid) curve and a cycloida! wheel is generated by a pin wheel (exte...

Mobile Robots are used to venture through types of environments where wheel slip is a threat. Wheel slip is a hazard to mobile robots in that it introduces error in dead reckoning measurement and in some instances causes the robot to halt is forward progress. To compensate for traction loss several methods are used to determine the terrain characteristics. One of these methods is Pacejka’s Tire...

The onset of the daily wheel running bout precedes dark onset by several hours in the early runner genetic variant of mice. Here, we test the hypothesis that timed daily administration of a melatonin agonist, ramelteon, or a benzodiazepine, triazolam, normalizes the timing of daily wheel-running rhythms in early runner mice. The daily profiles of wheel-running activity of early runner mice were...
