one of the most important requirements of developing appropriate strategies for international marketing is correct identification of target markets. using quantitative techniques and decision making skills will lead to better results regarding the evaluation of marketing strategies. in this study, first we have used internal factor evaluation (ife) matrix for recognizing and comparing strengths...
This study examines the accuracy and value of three different PV module performance modeling approaches by calibrating selected performance models to outdoor IV data measured on different module technologies. We compare measured and modeled IV characteristics by examining the error distributions and correlations with time varying quantities to assess the accuracy of each model for the modules t...
In order to study genetic diversity of different wheat inbred lines and grain yield modeling as well as selection of elite lines, 305 wheat lines derived from Roshan × Falat cultivar along with their parents as well as two check (Mahdavi and Shahpasand) cultivated in research field of Sahid Bahonar university of Kerman in augment design, on growing season of 2013-2014. Result of genetic and phe...
This paper presents the design and experimental evaluation of a six-cell 6-kW cellular (parallel) rectifier system which operates at nearly unity power factor. The cellular rectifier system implements both distributed load sharing and distributed ripple cancellation, eliminating the need for any centralized control. The implemented system mitigates some of the major drawbacks of its single-conv...
the present study is paid to the evaluation of the welfare program of the unemployment insurance in iran. the main purpose which was the main reason for performing this thesis, was the unemployment insurance plan’s challenges in iran such as financial problems of this plan, prolongation of the credit receipt for some insured people, unemployment slow exiting from the unemployment insurance fund...
Authentication is the preliminary security mechanism employed in information system to identify legitimacy of user. With technological advancements, hackers with sophisticated techniques easily crack single-factor authentication (username and password). Therefore, organizations started deploy multi-factor (MFA) increase complexity access system. Despite MFA increasing digital service, usable sh...
در سال های اخیر، کاربرد مدل های هیدرولوژیکی توزیعی بر پایه فیزیکی افزایش یافته است. با این حال بسیاری از سوالات در خصوص واسنجی و صحت سنجی صحیح مدل های توزیعی و ارزیابی عدم قطعیت پارامترهای تخمینی، هنوز هم ناشناخته است. به خصوص برای مدل های پیچیده، تخمین پارامترها به طور صحیح، کاهش فضای پارامتری و استفاده از الگوریتم های موثر و کارآمد به منظور کاهش عدم قطعیت و تسهیل فرآیند واسنجی امری ضروریست. ه...
در این تحقیق به بررسی پارامترهای بیلان آب حوضه رودخانه آق چای در شمال استان آذربایجان غربی، با مساحت 1440.89 کیلومتر مربع پرداخته شده است. مدل سازی بارش-رواناب با گام زمانی روزانه و با استفاده از مدل نیمه توزیعی swat و بهینه سازی پارامترهای حوضه، بررسی عدم قطعیت مدل و پارامترها با برنامه swat-cup انجام گرفته است. کاربرد الگوریتم sufi-2 در بررسی عدم قطعیت نشان داد مقدار ضریب ناش برای دوره واسنج...
Canadian and US genetic evaluations for July 1991 were combined for 3304 Holstein bulls evaluated in Canada that had US progeny or a cross-reference code. Canadian evaluations of the bulls and their sires and dams were converted to US PTA. Combined PTA were weighted averages of progeny information from both countries and parent average. Parent average was recomputed from the sire's combined eva...
