کاربرد موفقیتآمیز مدل های مفهومی بارش ـ رواناب(crr) به چگونگی واسنجی پارامترهای آنها بستگی دارد. مدل های crr عموماً دارای پارامترهای زیادی هستند که نمیتوان آنها را بصورت مستقیم اندازهگیری نمود و لازم است که آنها را در طول واسنجی مدل تخمین زد. هدف از انجام واسنجی، یافتن مقادیر آن سری از پارامترهایی است که باعث بهینه شدن معیارهای نیکویی واسنجی میشوند. با وجود عمومیت کاربرد این مدل ها، در صورتی...
طراحی بهینه سیستم پمپاژ و ذخیره آب یک مسئله غیر خطی پیچیده است. در این تحقیق مدلی بر اساس تلفیق رویکرد بهینه سازی تکامل رقابتی جوامع sce با نرم افزار شبیه سازی هیدرولیکی شبکه توزیع آب epanet,برای طراحی بهینه سیستم پمپاژ و ذخیره استفاده شده است.با توجه به قابلیت روش sce در زمینه بهینه سازی سیستم پمپاژ و ذخیره آب,مدل ارائه شده برای طراحی یک سیستم پمپاژ و ذخیره فرضی استفاده شده است.نتایج بدست آمده...
We study the e ects of communication in Bayesian games when the players are sequentially rational but some combinations of types have zero probability. Not all communication equilibria can be implemented as sequential equilibria. We de ne the set of strong sequential communication equilibria (SSCE) and characterize it. SSCE di ers from the concept of sequential communication equilibrium (SCE) d...
The genotoxicity study of ornidazole (ONZ) was carried out on human lymphocyte chromosomes, using sister chromatid exchange (SCE) and micronucleus (MN). Thirty-two patients with Entemoeba histolitica infection who received 1000 mg/day for 10 days were included in this study. SCE and MN were measured before and after therapy. A statistically significant increase was observed in the SCE (P < 0.00...
The effects of oral administration of sugar cane extracts (SCE) on Eimeria tenella oocysts infection in chickens were studied with 2 different experiments. In Experiment 1, 3-week-old inbred chickens (MHC; H.B15) were inoculated into the crop with SCE (500 mg/kg/day) for 1 day or 3 consecutive days, and then challenged with E. tenella sporulated oocysts (2 x 10(4) cells/chicken). In Experiment ...
The frequency of sister chromatid exchange (SCE) has been followed sequentially after the addition of SV40 to human diploid fibroblast cultures. The SCE frequency was nearly the same in uninfected controls and in infected cultures before they became tumor antigen positive. When cells exhibited tumor antigen, the SCE frequency increased over a wide range, and changes in chromosome number and str...
Homologous recombination involving sister chromatids is the most accurate, and thus most frequently used, form of recombination-mediated DNA repair. Despite its importance, sister chromatid recombination is not easily studied because it does not result in a change in DNA sequence, making recombination between sister chromatids difficult to detect. We have previously developed a novel DNA templa...
The job shop problem is an important part of scheduling in the manufacturing industry. A new intelligent algorithm named Shuffled Complex Evolution (SCE) algorithm is proposed in this paper with the aim of getting the minimized makespan. The sequence mapping mechanism is used to change the variables in the continuous domain to discrete variables in the combinational optimization problem; the se...
