This paper focuses on the large-scale experimental investigation of a novel, highly efficient, low-cost and easily constructible seismic isolation system, defined as PVC-Rollers Sandwich (PVC-RS) isolation. The proposed system is based placement spherical roller bearings between two PVC surfaces in sandwich configuration. configuration triggers desirable rolling behaviour rollers surfaces, thus...

Myofascial releasing rollers are muscle massage devices used by athletes, fitness enthusiasts, and those recovering from injury to enhance functional ability. OBJECTIVES: The purpose of this study was to assess the acute effects of self myofascial releasing rollers on muscle strength, power, and flexibility compared to static stretching and control. STUDY DESIGN: Thirteen adult recreationally t...

Hydrodynamic effects are known to significantly affect the collective behavior of wet active matter systems. However, non-linear many-body nature these interactions makes them very challenging analyze, particularly in dense suspensions. Quincke rollers one canonical examples artificial microswimmers. These particles that move freely above a plate due torque generated by uniform DC electric fiel...

In this study, heat transfer behavior in a rotating annular flow field is investigated via computational fluid dynamics. The subject to the study cylinders (rolls) widely used different fields of industry. heating or cooling function rollers provided by work moving area section under roller surface. working conditioned channel geometry directly related thermal performance roller. purpose invest...

This study aimed to determine the effect of angle changes on primary fixed sheave and roller mass torque, acceleration, engine power, top speed automatic motorcycles. type research is experimental research. The subjects in this were 125 cc motorcycles modified at rollers. angles change 14.5˚, 13.5˚, 12.5˚; while was 14, 13, 12 grams. testing began with tuning up motorbike, then installing units...

Response of a fabric to applied forces normal to its plane is known as fabric compressional behavior. It is one of the important properties that determine fabric performance in many applications. The principle of a system used to measure fabric compressional characteristics, online, is proposed in this paper. A controllable nip formed by a pair of rollers is employed to apply compressional defo...

In this paper, we purpose a new holonomic omni-directional mobile robot that can move on not only flat floors but also uneven environment. A prototype robot can move in omni-direction, run on the uneven floors and slopes, and pass over large steps. The robot has seven universal wheels that have twelve cylindrical free rollers. We adopt a passive suspension system that enable the robot to change...
