development and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولStructural physiological, and biochemical gradients in tobacco pith tissue.
Explants of tobacco pith taken at various distances from the apex of a mature stem show a sharp gradient in growth potential in vitro; growth is highest in the extreme apical and basal explants, and is minimal in explants removed ca. 75 cm from the apex. Calluses produced by the vigorously growing basal explants are harder and more compact than those produced from more apical explants. The grad...
متن کاملHormonal control of tobacco crown gall tumor morphology.
The endogenous levels of auxin and cytokinin in teratoma and unorganized tobacco (Nicotiana tabacum L. var Wisconsin #38) crown gall tumor tissues were determined. Teratoma tissues contain levels of auxin and cytokinin favorable for shoot formation, whereas unorganized tumors contain levels of auxin that suppress shoot formation. This conclusion is based upon the observation that when levels of...
متن کاملCytokinin effects on growth of quiescent tobacco pith cells.
Excised pith tissue from Nicotiana glauca or the tumor-prone hybrid N. glauca x N. langsdorffii has no growth requirement for exogenous cytokinins. Addition of kinetin to cultures of these lines results in growth inhibition at a kinetin concentration 1000-fold lower than the optimal level for kinetin-requiring lines. Cytological comparison of the kinetin-inhibited 2N hybrid and glauca tissues w...
متن کاملEffectiveness of Tobacco Control Measures in Reducing Tobacco Use among Adolescents and Young Adults in Anuradhapura, Sri Lanka
Background: Sri Lanka became a signatory to the WHO Framework Convention on Tobacco Control in September 2003 and ratified in November 2003. Aiming to reduce tobacco burden in Sri Lanka, National Authority on Tobacco and Alcohol Act [NATA] No. 27 was authorized in 2006. The objective of this study was to assess the behavioral changes related to tobacco use among adolescents and young adults fol...
