this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.
یکی از ویژگی های اساسی مواد هادی مقاومت الکتریکی آن هاست که با داشتن تعداد الکترونهای آزاد لایه ظرفیت می توان مقاومت الکتریکی آن ماده را پیدا نمود. با اندازه گیری مقاومت الکتریکی مواد می توان ویژگیها و مشخصات ماده را تعیین نمود. در این پایان نامه بنا داریم به اندازه گیری مقاومت الکتریکی با استفاده چهار پراب همراستا با فاصله ثابت از هم که در تماس با سطح یک ویفر سیلیکونی هستند اقدام کنیم. در عم...
یک کنترل کننده pid ( تناسبی- انتگرال گیر – مشتق گیر) یک ابزار متعارفی است که در کاربردهای کنترل صنعتی استفاده می شود. یک کنترلکننده pid می تواند برای تنظیم سرعت، دما، جریان، فشار و سایر پروسه های متغیر استفاده شود کنترل کنندهpid می تواند نزدیک سنسور (حسگر) با وسیله تنظیم کنترل جاسازی شود وبا استفاده از سیستم اسکادا (scada)به طور مرکزی از طریق مانیتور کنترل شود . یک کاربرد نوعی (typical) کنترل...
for the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. when the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. in this paper we will consider the polynomial planar vector fields ...
abstract al- muntazam by ibn al -jawzi is one of the greatest the book ancient book of texts on history of islam in the 6th century.it is very important one;because of including rare reports which are not found any where.in addition to historical reports,his outlook , in which embodies information on mythologies, milal wa nihal (sects and creeds), geography, and political, social and religiou...
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.
