در این تحقیق به مکانیزم انتقال حرارت کابل های نصب شده در زمین، روش های حل عددی این معادلات مانند روش المان محدو و روش حجم محدود پرداخته می شود.در این پروژه اثر عمق نصب کابل های زمینی، مشخصات فیزیکی خاک در برگیرنده کابل نظیر مقاومت حرارتی و اثر ناهمگنی توسط روش های حل عددی معادلات حرارت، بررسی می گردد.

افزایش هزینه یکی از مباحثی است که همواره بر موفقیت پروژه اثر منفی داشته و به دو قسمت سرریز هزینه و اتلاف مالی تقسیم میشود. سرریز هزینه به معنای تفاوت حاصل از قیمت واقعی و قیمت تخمینی پروژه می باشد و منظور از اتلاف هزینه، هزینه هایی است که در قبال فعالیتها و رخدادهایی داده می شود که هیچ نقش مثبتی در فرآیند پروژه نداشته و ارزش افزوده ای ایجاد نمی‌کنند. این پژوهش به مقوله دوم یعنی اتلاف هزینه در س...

Background: The Pabon Lasso graphical Model is a method to determine hospital efficacy as one of the most important part of health system in developing countries. This study aimed  at assessing the efficacy analysis using Pabon Lasso Model and comparing with national standards of educational hospitals affiliate to Qom University of Medical Sciences. Materials and Methods: This descriptiv...

Background and Aim: All hospitals need to be monitored and continuously evaluated. Pabon Lasso graphical model assesses the efficiency of hospitals using a combination of their input data and performance indicators. The aim of this study was to determine the effects of Iran Health System Evolution Plan on Tehran University of Medical Sciences (TUMS) hospitals’ performance indicators using the P...

Background and Aim: In the field of health, due to the limited resources and sensitivity of the subject of treatment, performance evaluation gains more importance. The main objective of this research was to evaluate the performance of two hospitals in Torbat Heydarieh city based on the PABON LASSO model and to compare the performance indicators with national standards during 2014-2015. Methods...

Background and Objective: The evaluation of the hospitals performance in order to improve the quality of services provided is of great importance. This study aimed to evaluate the performance of teaching hospitals affiliated to Shiraz University of Medical Sciences (SUMS) using Pabon Lasso graph before and after the implementation of the health system transformation plan. Materials and Metho...

Introduction: Efficiency indicators are the most important ways to measure hospitals performance, but the individual application of these indicators can result in misleading hospital performance measurement. The application of simultaneous indicators can eliminate many problems in the case of hospital performance measurement therefore, through using Pabon Lasso Model, the indicators at universi...
