leishmaniasis has long been known as a significant public health challenge in many parts of iran. phlebotomus papatasi and p. sergent i are the vectors of zoonotic cutaneous leishmaniasis and anthroponotic cutaneous leishmaniasis respectively, and 5 species of sand flies including p. kandelakii , p. neglectus , p. perfiliewi , p. keshishiani and p. alexandri are considered as probable vectors...
Matrix Converter (MC) is a direct energy conversion device with high input power factor. In the Direct Matrix Converter modulation, the Space Vector Modulation (SVM) method by simultaneous control of the input current and output voltage is used. In this method sum of the phase voltages in the central point of load is nonzero, then nonzero Common-Mode Voltage (CMV) in central point is produce...
this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
in this paper, rstly, it is proved that, for a fuzzy vector space, the set of its fuzzy bases de ned by shi and huang, is equivalent to the family of its bases de ned by p. lubczonok. secondly, for two fuzzy vector spaces, it is proved that they are isomorphic if and only if they have the same fuzzy dimension, and if their fuzzy dimensions are equal, then their dimensions are the same, however,...
درایوهای بدون جاروبک dc با توجه به بهره وری بالا، چگالی توان بالا، سهولت کنترل و نگهداری راحتتر، به طور گسترده ای در وسایل نقلیه الکتریکی و برنامه های کاربردی خودرو به عنوان موتور یا ژنراتور استفاده می شوند. ابتدا، این پایان نامه مروری بر جنبه های مختلف موتورهای bldc شامل ویژگی ها، مدل سازی، اینورترهای مورد استفاده و تحلیل روش های مختلف کنترلی و بیان نکات پیاده سازی درایو موتور bldc می پردازد....
zoonotic cutaneous leishmaniasis (zcl) is an increasing and important public health problem in iran. the use of repellents is recommended as one of the important means of personal protection against vectors of zcl. this paper reports the repellency effect of the plant myrtle, myrtus communis (myrtaceae), essential oil for protection against 3-7-day-old unfed females of the sandfly, phlebotomus ...
