accurate and correct performance of controller in cruise control systems is important. hence, in such systems, controller should optimize itself against noise and probable changes in system dynamic. as a matter of fact, in this article three approaches have been conducted to-ward this purpose: mit, direct estimation and indirect estimation. these approaches are used as controllers to track refe...
در این پایان نامه به مسئله شبیه سازی حرکت هواپیما توسط یک رباط موازی پرداخته می شود. جهت دستیابی به هدف مذکور ابتدا حرکت هواپیما را شبیه سازی می کنیم. برای شبیه سازی حرکت هواپیما، معادلات دینامیکی حاکم بر هواپیما را بطور عام استخراج می نماییم. نیروها و ممان های وارده بر هواپیما در معادلات دینامیکی مذکور، شامل نیروها و ممان های وارده بر هواپیما در معادلات دینامیک مذکور، شامل نیروها و ممان های آئ...
هدف: در این مطالعه به بررسی رابطه درد پستان و سرطان پستان در خانم های ایرانی در سال های 90-1389 پرداختیم. روش مطالعه: این مطالعه به صورت یک بررسی مشاهده ای (observational) طولی (longitudinal) از نوع مورد - شاهدی (case-control) انجام گردیده است. جامعه مورد بررسی شامل 96 نفر بود که 48 نفر مبتلا به سرطان پستان (گروه مورد) و 48 نفر غیرمبتلا به سرطان پستان (گروه شاهد) بودند. نتایج: 80 درصد از افرا...
Introduction The public highway systems are used to transport a constantly increasing number of goods and people. In spite of that high increase in traffic, the number of fatal accidents is falling yearly, because of the ever increasing use of technology to develop safer vehicles. Meanwhile, the environmental impact of each vehicle decreases proportionally in that technology partly compensates ...
This paper describes the design, fabrication, and analysis of an experiment that demonstrates the stability and control system characteristics of an aircraft constrained at the center of gravity in an air flow field. Given a set of basic requirements, the physical system (including the airframe, wings, tail, and mounted ball bearing) was designed, modeled, and manufactured. With the aircraft pl...
In this paper a control system has been designed to improve traffic conditions in car following maneuver. There are different methods to design a control system. In this paper design approach is based on the Fuzzy sliding mode control (FSMC) system. The aim of designing FSMC system is to achieve safe and desire longitudinal distance and less lateral displacement. In orde...
Self-regulatory processes are believed to be critical to early personality and behavioral adjustment. Such processes can be observed on multiple levels, including the physiological, attentional, emotional, cognitive, and interpersonal domains of functioning. Data from several longitudinal studies suggest links between early temperamental tendencies such as behavioral inhibition and frustration ...

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
