background: physical wedges are still widely used as beam modifiers in external beam radiotherapy. however the presence of them in the beam trace may cause beam hardening which may not be considered in many treatment planning systems. the aim of this study is to investigate the beam hardening effect generated by physical wedges via different beam quality indexes as photon spectrum, half value l...

ابتدا مروری بر انواع خودروهای بدون سرنشینuvs)) صورت خواهد گرفت. سپس الگوهای تولید مسیر(trajectory planning) ومشخصات آنها در محیطهای استاتیک ودینامیک مورد بحث قرار خواهند گرفت. محیط استاتیک به این معناست که اشیاء (که می توانند مانعی برای uvsباشند) ساکن هستند ودر محیط دینامیک موانع می توانند متحرک باشند. یکی از چالشهای مربوط به انجام ماموریت یک خودروی بدون سرنشین درهرمحیطی اعم از استاتیک یا دینام...

Due to the complexity of assembly processes, a high ratio of tasks is still performed by human workers. Short-cyclically changing work contents due to smaller lot sizes, especially in the varied series assembly, increases both the need for information support as well as the risk of rising physical and psychological stress. The use of technical and digital assistance systems can counter these ch...

This study tested several relationships predicted by the Health Action Process Approach (HAPA) in a sample of 175 generally healthy, inactive, middle-aged women (40-65 yrs old) over a 12 week period. Participants' physical activity, risk perceptions, outcome expectancies, action self-efficacy and intention were measured at baseline. Planning and maintenance self-efficacy were measured 4 weeks l...

Introduction: In this regard, one of the priorities of urban planning is improving citizen security. According to fast urbanism development, one of the managers and urban planners' concerns is increasing citizen sense. Sometimes physical proceedings such as protection, guarding, control are planned in urban spaces to achieve and intensification urban security, whereas increasing citizens' secur...

 The purpose of this study was to prioritize the factors affecting the management information system (MIS) in the productivity of the physical education department of the Islamic Azad University of Isfahan. The research method is descriptive, applied based on the purpose and applied with a survey approach. The statistical population of this study includes all heads, principals and directors of ...

Many real-world problems can be expressed in terms of states and actions that modify the world to reach a certain goal. Such problems can be solved by automated planning. Numeric planning supports numeric quantities such as resources or physical properties in addition to the propositional variables from classical planning. We approach numeric planning with heuristic search and introduce adaptat...

Robotic manipulation is important for real, physical world applications. General Purpose manipulation with a robot (eg. delivering dishes, opening doors with a key, etc.) is demanding. It is hard because (1) objects are constrained in position and orientation, (2) many non-spatial constraints interact (or interfere) with each other, and (3) robots may have multidegree of freedoms (DOF). In this...

A recent legal trend involves the resolution of disputes between health plans and nonparticipating providers. These individuals have not entered into a formal participation or services agreement with the health plan, but they may be eligible for and legally entitled to reimbursement for services rendered to plan participants. Resolution of these disputes can hinge on a number of factors, includ...
