چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Abstract Aim: The purpose of this study was to compare the efficacy of reality group therapy on irrational beliefs, psychological hardiness and academic achievement of brilliant talented students. Method: This study was a experimental, pre-test, post-test and control group with 6-month follow-up. The statistical population of the study consisted of brilliant talented students of secondar...
This paper proposes a new method for online secondary path modeling in feedback active noise control (ANC) systems. In practical cases, the secondary path is usually time-varying. For these cases, online modeling of secondary path is required to ensure convergence of the system. In literature the secondary path estimation is usually performed offline, prior to online modeling, where in the prop...
Background & Aim: Traumatic brain injury management focuses on the prevention and treatment of secondary brain injuries. The aim of this study was to adapt a clinical guideline (CG) for nursing care of secondary brain injuries in adults. Methods & Materials: This study was carried out through a multi-stage evolutionary study at Isfahan University of Medical Sciences in 2017. Based on the opini...
The purpose of this paper is to analyze the flow field structure in transient state and performance of secondary injection system for thrust vectoring in divergent section of a two-dimensional nozzle. Secondary injection for thrust vectoring in a two-dimensional nozzle is studied by solving three-dimensional Reynolds-averaged equations by means of fluent solver. Spalart-allmaras model was used ...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
the mortality associated with secondary peritonitis has been unacceptably high. this is despite improvements in diagnosis and surgical methods. the risk factors affecting outcome have been only partially elucidated the records of 303 patients with the established diagnosis of generalized peritonitis were studied retrospectively for various prognostic factors and their outcomes. the associations...
