The aim of this paper is to introduce - by general analytical nonlinear and then optimal design with vector control a hybrid electric and electric vehicles (HEV/EV) electric propulsion system for 50/100 kW, 1350-7000 rpm (600 Nm peak torque/40 kg) at above 91% overall efficiency 300 Vdc battery for a peak phase current of 520 A. After searching quite a few(More)
The goal of this work was to identify the biotechnogical conditions (i.e. inoculum concentration, nutrional sources (carbon and nitrogen), pH and time of cultivation) for improving the yield of biomass production of Pleurotus ostreatus by cultivation on submerged culture conditions. The submerged cultivation was done in Erlenmeyer vessels in rotary shaker(More)
A convenient way of controlling the magnetic anisotropy of electrodeposited cobalt nanowires was studied. The nanowires were grown by electrodeposition into the cylindrical pores of a polycarbonate membrane. Using ferromagnetic resonance and transmission electron microscopy, it was demonstrated that changes in the two main electrodeposition parameters(More)
Micro Raman spectroscopy was applied to investigate the speciation of heteropoly and isopoly molybdates in 0.05 and 0.005 M aqueous solutions of 12-molybdophosphoric acid at pH values between 1 and 6. For comparative purposes, (31)P NMR spectroscopy was applied too. It is shown that stability of Keggin anion is influenced both by pH and concentration of(More)
