Background and Objectives: The Health System Evolution Plan was developed to improve quality and accessibility of health care services and reduce the costs to protect people from catastrophic out of pocket payments. The aim of current study is investigatation of Health System Evolution Plan effects on performance indices of governmental hospitals affiliated to Iran University o...

Introduction: The selection of suitable beam angles and weights in external-beam radiotherapy is at present generally based upon the experience of the planner. Therefore, automated selection of beam angles and weights in forward-planned radiotherapy will be beneficial. Material and Methods: In this work, an efficient method is presented within the MATLAB environment to investigate how to improv...

Introduction: Appropriate definition of the distance measure between diffusion tensors has a deep impact on Diffusion Tensor Image (DTI) segmentation results. The geodesic metric is the best distance measure since it yields high-quality segmentation results. However, the important problem with the geodesic metric is a high computational cost of the algorithms based on it. The main goal of this ...

in this paper, we have tried to analyze and asses the process of formation and spatial – structural evolution of iranian-islamic cities through tehran case study as well as how to organize and effecting different factors specially modernism on urban elements. also we have discussed about formation and emergence of tehran and the effect of different pre modernism and postmodernism socio-economic...

this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...
