due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
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...
in this paper direct proofs of some common fixed point results for two and three mappings under weak contractive conditions are given. some of these results are improved by using different arguments of control functions. examples are presented showing that some generalizations cannot be obtained and also that our results are distinct from the existing ones.
in this paper, by using four functionals fixed point theorem, we obtain sufficient conditions for the existence of at least one positive solution of an $n$th-order $m$-point boundary value problem. as an application, we give an example to demonstrate our main result.
انمی داسی شکل و ا نمی کولی جز شایع ترین بیماریهای وراثتی در انسان ها در سرتاسر دنیا بوده که هزینه های درمانی هنگفتی را بر بیماران و سیستم بهداشتی کشورها می گذارد. انمی داسی شکل اولین اختلال ژنتیکی بوده که در حدود 58 سال پیش مکانیسم ژنتیکی اش توصیف شده و اختلالش ناشی از یک point mutation در زنجیره بتای همو گلوبین می باشد که سبب dysfunction پروتین هموگلوبین شده و عامل عوارض بالینی در مبتلایان می ...

Early electroacupuncture treatment ameliorates neuroinflammation in rats with traumatic brain injury
BACKGROUND Neuroinflammation is the leading cause of neurological sequelae after traumatic brain injury (TBI). The aim of the present study was to investigate whether the neuroprotective effects of electroacupuncture (EA) are mediated by anti-neuroinflammatory effects in a rat model of TBI. METHODS Male Sprague-Dawley rats were randomly divided into three groups: sham-operated, TBI control, a...
