BACKGROUND Accounts of evidence are vital to evaluate and reproduce scientific findings and integrate data on an informed basis. Currently, such accounts are often inadequate, unstandardized and inaccessible for computational knowledge engineering even though computational technologies, among them those of the semantic web, are ever more employed to represent, disseminate and integrate biomedic...
The dynamic response of an RF MEMS device to a timevarying electrostatic force is optimized to enhance robustness to variations in material properties and geometry. The device functions as an electrical switch, where an applied voltage is used to close a circuit. The objective is to minimize the severity of the mechanical impact that occurs each time the switch closes, because severe impacts ha...

در این پایان نامه طراحی بهینه ای چند هدفی کنترلرهای مقاوم برای سیستم هایی با پارامترهای نامعین احتمالاتی مد نظر می باشد. برای بهینه سازی چند هدفی الگوریتم muga پیشنهاد شده است و از آن برای بهینه سازی چند هدفی چندین مورد مطالعاتی شامل سیستم دو جرم-فنر و سیستم مرتبه اول با تاخیر زمانی استفاده شده است. توابع هدف انتخابی از دیدگاه طراحی بر اساس قابلیت اطمینان (احتمال شکست توابع هدف) همانند احتمال ش...
در این پایان نامه طراحی بهینه چندهدفی کنترلرهای مقاوم برای سیستم هایی با پارامترهای نامعین احتمالاتی به کمک شبکه عصبی از نوع gmdh مدنظر می باشد. در طراحی کنترلرهای مقاوم برای سیستمهای دارای پارامترهای نامعین احتمالاتی، از دو دیدگاه طراحی مقاوم (rdo) و طراحی براساس قابلیت اطمینان (rbdo) استفاده میشود. در طراحی براساس قابلیت اطمینان احتمال شکست کنترلر نسبت به بعضی قیود طراحی(توابع حالت حدی) محاسب...
Due to the popularization of digital image capturing devices, video content is growing in volume every year. To compress the huge amount of data to much smaller capacity so that it can be manipulated with low cost for video conference, broadcasting, online video-on-demand and surveillance system, video coding technology has been developed since 1989. H.264/AVC is the latest international standa...
Today, FE-simulation of forming process has become an integral part for assessing and evaluating forming processes. The optimization, i.e. improvement of product characteristics, has been an integral part of forming simulation based virtual product development for several years now. On the other hand, the robustness of forming processes is becoming more and more focused on recently. Therefore t...
Learn about significant new improvements to MPEG-2 Video coding, how this enables more services to legacy set-top boxes and receivers, and about the revolutionary new TANDBERG EN8100 Advanced MPEG-2 Broadcast Encoder. ABSTRACT Broadcasters are required by federal regulation, and locked into in practice due to the millions of consumer digital televisions (DTVs) purchased, to use the MPEG-2 Video...
OBJECTIVE To estimate the occurrence and school-level clustering of drug involvement among school-attending adolescent youths in each of seven countries in Latin America, drawing upon evidence from the PACARDO research project, a multinational collaborative epidemiological research study. METHODS During 1999-2000, anonymous self-administered questionnaires on drug involvement and related beha...
