IT has been frequently observed that in some series of kindred reactions the activation energy of the process appears to be functionally related to the respective frequency factor A . For example, when one investigates a reaction taking place in various solvents, one often finds that E (the ...
Energy expenditure and wing beat frequency in relation to body mass in free flying Barn Swallows (Hirundo rustica) 来自 掌桥科研 喜欢 0 阅读量: 46 作者:CA Schmidt-Wellenburg,H Biebach,S Daan,GH Visser 摘要: Many bird species steeply increase their body mass prior to migration. These fuel ...
This paper mainly deals with the relation between energy efficiency and parameters of rare earth permanent magnet synchronous motor (REPMSM)operating under periodical load. The optimal parameters of the motor objected to the apparent efficiency by Powell method are obtained. The reseach provides theoreti...
The M-MSCs exhibited an areal capacitance of 153 lF cm-2 and a frequency characteristic (f0) of 5.6 kHz in aqueous electrolyte. Moreover, by employing suitable ionic liquid as electrolyte, the voltage window was expanded to 2 V and the f0 could be pushed to 6.6 kHz relying on the ...
Optimal frequency for flow energy harvesting using flapping foils and its relation with wake instability Inspired by the correlation between the propulsion efficiency of a flapping foil propeller and stability of the wake behind it (which leads to the optimal Strouhal number for propulsion), we numeri...
