during repetitive tasks (such as running, walking and tapping), music can effect on body movement rhythm. the purpose of this study is investigated the effect of music meter and tempo on cycling speed. therefore, seventeen female physical education students with 22.33±1.22 age, 57.23±10.30 weight, 22.09±3.5 body mass index and 160.55±4.6 height were selected and examined during four sessions (e...

a variety of anthropometric and training characteristics have been identified as predictor variables for race performance in endurance and ultra-endurance athletes. anthropometric characteristics such as skin-fold thicknesses, body fat, circumferences and length of limbs, body mass, body height, and body mass index were bi-variately related to race performance in endurance athletes such as swim...

This paper deals with the performance analysis of a proton exchange membrane fuel cell in automotive applications and especially for start/stop phases. Start-Stop cycles are one main sources degradation systems, embedded applications, among other dynamic conditions as idling, load cycling or high power. In this study, polarization curves electrochemical impedance spectra used to analyze mechani...

Degradation of polymer electrolyte membrane fuel cells (PEMFC) is investigated through an accelerated stress test (AST) consisting load-induced humidity cycling combined with open circuit voltage. This stressor-AST was designed to mimic real operating conditions. Commercially available membrane-electrode assemblies initial voltage about 0.7 V at 0.5 A cm?2 showed a performance drop 900 ?V h?1. ...

Structural rejuvenation is an effective measure to optimize the mechanical properties of metallic glasses (MGs). Sophisticated solutions include thermal cycling, laser shocking, and multiaxial stress loading. Here, we propose easy-to-operate cycling as alternative strategy tailor relaxation, deformation, structural heterogeneity MGs. in a La-based MG achieved via even at very few cycles (102 te...

Primary load-bearing members used in glass structures, such as columns consisting of panels, are frequently subjected to in-plane loading. Its allowable stress for safety design appears be a significant subject. By analyzing the results static (without repeated loading) and cycling compression loading tests, authors explore mechanical features failure mechanism tempered panels subjective loadin...
