Two stream instability in plasma is simulated by PIC method. The execution time of the sequential and parallizable sections of the program is measured. The sequential program is parallelized with the help of the MPI functions. Then, the execution time of the sequential program versus the number of the grid points and the execution time of the parallel program on 3 and 5 processors versus the nu...

اولین سیستمهای قدرتی که مورد بهره برداری قرار گرفتند dc بودند(.آمریکا)1882 ولی بعدازاختراع ترانسفورماتور، بتدریج سیستمهای ac جایگزین سیستمهای dc موجود شدند . امروزه نیز اکثر سیستمهای قدرت از نوع ac می باشد. ولی در موارد خاصی کاربرد خطوط انتقال جریان مستقیم اجتناب ناپذیر است . مثلا دراتصال دو شبکه با فرکانسهای مختلف یا انتقال انرژیهای بالا در فواصل طولانی و یا اتصال شبکه های ac توسط کابل از زیر ...

the nutritional requirements of mammalian embryos changes throughout pre-implantation period, coincident with changes in the secretion of the female reproductive tract. therefore, it has been suggested that sequential culture media may support nutritional requirements for optimal growth of the mammalian embryos. in this study, we investigated the effect of two different concentrations (10 or 10...

use of saline water for irrigation has shown considerable promise. however, its effect on the solubility and bioavailability of native soil nutrients is not well understood. this study was conducted to evaluate the effects of salinity on the behavior of zinc(zn) in calcareous soils. the soil samples with different physiochemical properties were collected from four locations in khorasan province...

Bounds on test sequence length can be used as a testability measure. We give a procedure to compute the upper bound on test sequence length for an arbitrary sequential circuit. We prove that the bound is exact for a certain class of circuits. Three design rules are specified to yield circuits with lower test sequence bounds.

An upper bound is given on the cutoff rate of discrete memoryless channels. This upper bound, which coincides with a known lower bound, determines the cutoff rate, and settles a long-standing open problem.

Spend your time even for only few minutes to read a book. Reading a book will never reduce and waste your time to be useless. Reading, for some people become a need that is to do every day such as spending time for eating. Now, what about you? Do you like to read a book? Now, we will show you a new book enPDFd asynchronous operators of sequential logic venjunction sequention that can be a new w...
