Investors use different approaches to select optimal portfolio. so, Optimal investment choices according to return can be interpreted in different models. The traditional approach to allocate portfolio selection called a mean - variance explains. Another approach is Markov chain. Markov chain is a random process without memory. This means that the conditional probability distribution of the nex...
یکی از مهمترین بلایایی که مناطق خشک و نیمه خشک را تحت تاثیر قرار می دهد و در زمره عوامل تهدید کننده حیات بشری و تخریب منابع طبیعی محسوب می شود بیابان زایی است، بنابراین شناخت و پیش بینی این پدیده از اهمیت بسزایی برخوردار است. در این راستا به منظور بررسی وضعیت بیابان زایی منطقه شرق و جنوب اصفهان از تصاویر ماهواره لندست 4 و 7 و 8 در 5 دوره 1986، 1994، 2000، 2008 و 2016 استفاده گردید. شاخص ndvi بر...
conclusions the use of sof + pr regimen or ldv/sof can significantly reduce the incidence of complications associated with the disease. for example, short and long-term outcomes are better than the current drug regimens for hcv genotype 1 patients in all stages of the disease. objectives this study is aimed to assess the cost-effectiveness of the three drug regimens of pegylated interferon and ...
in this paper, first a great number of inverse problems which arise in instrumentation, in computer imaging systems and in computer vision are presented. then a common general forward modeling for them is given and the corresponding inversion problem is presented. then, after showing the inadequacy of the classical analytical and least square methods for these ill posed inverse problems, a baye...
Background: The liver is the largest internal organ and the most important organ after heart and brain in the human body without which life is impossible. Diagnosis of liver disease requires a long time and sufficient expertise of the doctor. Statistical methods can be classified as an automated forecasting system and help specialists for quickly and accurately diagnose liver disease. Hidden Ma...
Planning for supply water demands (drinkable and irrigation water demands) is a necessary problem. For this purpose, three subjects must be considered (optimization of water supply systems such as volume of reservoir dams, optimization of released water from reservoir and prediction of next droughts). For optimization of volume of reservoir dams, yield model is applied. Reliability of yield mod...
State wide variant topographic features in North Carolina attract the hydro-climatologist. There is none modeling study found that predict future Land Cover Land Use (LCLU) change for whole North Carolina. In this study, satellite-derived land cover maps of year 1992, 2001 and 2006 of North Carolina were integrated within the framework of the Markov-Cellular Automata (Markov-CA) model which com...
