nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
در حالت کلی معادلات دیفرانسیل با مقادیر اولیه را نمی توان دیفرانسیل می توان جواب طیف وسیعی از مسائل کاربردی را مشخص نمود با روش های تئوری حل نمود، لذا با حل عددی معادلات یک حالت خاص از مسأله مقدار اولیه، مسأله ای به فرم: y^=f(x,y) , y(a)=?, y^ (a)=?^^ است که مشتق اول در آن ظاهر نمی شود. این معادلات طیف وسیعی از پدیده های اطراف ما را شامل می شود، مثلاً معادلاتی که دارای جواب نوسانی هستند از ...
Introduction: Resuscitation self-efficacy is defined as a judgment of perceived capability to organize and execute the process of care during cardiopulmonary resuscitation. It is believed to be an important factor in teaching vital nursing skills especially cardiopulmonary resuscitation. Therefore, this study aimed to investigate the impact of mannequin-based simulation and computer-based simul...
Automated office systems are emerging as an interdisciplinary research area with a strong computer science component. In this paper we define office information systems as entities which perform document storage, retrieval, manipulation and control within a distributed environment. Some state of the art implementations are described. We relate the research to different areas of computer science...
High power densities in current SoCs result in both huge energy consumption and increased chip temperature. This paper proposes a temperature-aware dynamic voltage selection technique for energy minimization and presents a thorough analysis of the parameters that influence the potential gains that can be expected from such a technique, compared to a voltage selection approach that ignores tempe...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
