混合动力车辆的电磁兼容试验

随着混合动力车辆（HEV）的日益普及应用，产生的电磁兼容（EMC）问题逐渐引起了人们的重视。HEV 内部集成了大量的高压、大功率电子器件，采用传统燃油车的EMC 试验方法并不完全适用于HEV 的测试。本文提 出了HEV 测试的基本试验配置，以关键部件电源逆变器、电机为例，对测试配置进行了详细的说明。最后，谈到了 负载和转速变化的瞬态过程测试，以及人工电源网络（AN）在HEV 试验中遇到的问题。     

Dihydropyrazole and dihydropyrrole structures based design of Kif15 inhibitors as novel therapeutic agents for cancer

Mitotic Kinesin motors, Eg5 and Kif15, have recently emerged as good targets for cancer as they play an inevitable role during mitosis. But, most of the Eg5 inhibitors were found ineffective when the cancer cells develop resistance to them by escalating the expression of Kif15 as alternative to Eg5. Therefore, the drugs that target Kif15 became necessary to be used either as a single or in combination with Eg5 inhibitors. The present study used 39 dihydropyrazole and 13 dihydropyrrole derivatives that were having in vitro inhibitory potential against kinesin motors to develop a common pharmacophore hypothesis AHRR and atom-based QSAR model. The model was used for virtual screening of ZINC database and the resultant hits were docked against Kif15. The four drug candidates with high docking score were examined for their activity and pharmacokinetic behaviour. Based on the results these drugs could be considered as lead candidates in further drug development for cancer.     

Specific accelerating factor: One more tool in motor sizing projects

This work is focused on improvement of motor sizing methods based on the accelerating factor [4]. This quantity is used to seek commercial motor–gearbox couples for mechatronics; unfortunately, it does not allow comparison of different acceptable solutions. The designer must therefore make a choice based on experience, instinct and poor data of catalogues. A per-unit-length value of the accelerating factor (specific accelerating factor) gives instead a rough but consistent idea of a servo-motor quality, for a more systematic and thoughtful selection. The specific accelerating factor represents a “benchmark” for a motor, it’s easy to calculate from datasheets and was defined using well known notions of electromechanical design (under certain assumptions).
