Simulation and evaluation of a high resolution VIP PEM system with a dedicated LM-OSEM algorithm.
Over the last two decades there have been a growing number of designs for positron emission tomography (PET) cameras optimized to image the breast. These devices, commonly known as positron emission mammography (PEM) cameras allow much more spatial resolution by putting the photon detectors directly on the breast. PEM cameras have a compact geometry with a restricted field of view (FOV) thus ex...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

این پایان نامه کتاب زبان انگلیسی پایه هفتم(پراسپکت 1) را بر اساس چک لیست کانینگ ورث (1995) مورد ارزیابی قراردهده و نقاط قوت و ضعب کتاب مذکور را بررسی می نماید. در گام دوم نیز از طریق مصاحبه با تعدادی از دبیران زبان انگلیسی که کتاب مورد نظر را تدریس می کنند، نظر دبیران را در مورد پراسپک 1 جویا می شود.
Energy Management Simulation in a PEM Fuel Cell System
In this research the simulation of an air independent Proton Exchange Membrane Fuel Cell (PEMFC) propulsion system was taken into consideration. The system consists of several parts including PEM fuel cell stack, metal hydride and liquid oxygen (LOX) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. The heat recovery...
