background:the different duration of delay to first contact with a psychiatrist in depressive disordered patients has been observed in western and non western cultures. this study aimed to examine the duration and predictive factors of delay in contact with a psychiatrist in depressive patients in isfahan city of iran. methods:in this cross sectional study 156 depressive patients were recruited...
In this paper a Model Predictive Method based controller is proposed to control a satellite. Model Predictive Control (MPC) has been well known as a practical control method for various systems in industry. A problem with this method is its computational effort and time consuming. To reduce computational load Laguerre functions have been proposed in this literature. Simulation results are...
Background and Objectives: Pneumothorax is a life-threatening complication and the most common cause of which is trauma. Early diagnosis and treatment of Pneumothorax are very important. The aim of this study was to compare the diagnostic values of four-point and double-point ultrasound versus CT scan in determining pneumothorax in Rasul-Akram and Hafte-Tir Hospitals during the years 2015 - 201...
A nonlinear model predictive control (NMPC) algorithm based on neural network is designed for boiler- turbine system. The boiler–turbine system presents a challenging control problem owing to its severe nonlinearity over a wide operation range, tight operating constraints on control move and strong coupling among variables. The nonlinear system is identified by MLP neural network and neur...
the human major histocompatibility complex (mhc) plays a crucial role in transplantation, transfusion, paternity test and assessment of susceptibility to some diseases associated with hla-b27. three of the most fashionable methods for determination of hla antigens in clinical and research laboratories are microlymphocytotoxicity (mlct), flowcytometry and polymerase chain reaction (pcr). the pur...
on the substantive and predictive validity facets of the university entrance exam for english majors
this study examined the substantive and predictive validity facets of the university entrance examination for english major (ueeem) students. to that aim, 111 english major students were recruited to report their scores on each of the subtests of the test as well as their grade point average. sequential multiple regressions and factor analysis were used in the analysis of the data. results ackn...
پدیده ی تشکیل رسوب واکس در مخازن نفتی در مراحل مختلف تولید، انتقال و فرآوری مشاهده می شود. رسوب واکس منجر به گرفتگی خطوط لوله و تجهیزات عملیاتی، افزایش افت فشار، افزایش ویسکوزیته ی مایع و به تبع آن افزایش هزینه های پمپ کردن می شود.علاوه بر این، توقف فرآیند جهت حذف واکس های رسوب کرده باعث اعمال هزینه های سرسام آوری به واحد می گردد. لذا جلوگیری از تشکیل رسوب واکس از اهمیت به سزایی برخوردار می باش...
