For the successful tree establishment, an evaluation of land suitability is necessary.In this paper, we demonstrate how to implement fuzzy classification of land suitability in aGIS environment for afforestation with Juglans regia in Gharnaveh Watershed of GolestanProvince in Iran. Juglans regia is one of the most important agro-forestry species in manyrural parts of Iran. Relevant criteria for...

Water resources suitability is one of the most important factors to sustainabilityutilization of natural potential by rangeland grazing suitability. To determine this factor inshort time, low cost and high accuracy are most challenges of experts and ranchers. Usingsuitable technique for this subject can be sustainable utilization comprising from rangelandecosystems according to its degradation ...

Bioclimate envelope models have been widely used to illustrate the discrepancy between current species distributions and their potential habitat under climate change. However, the realism and correct interpretation of such projections has been the subject of considerable discussion. Here, we investigate whether climate suitability predictions correlate to tree growth, measured in permanent inve...

electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. the results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. in addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobarbitu...

In this paper, using Thevenin’s theorem and also nonlinear Lambert W function, a novel two-diode model of photovoltaic cells is presented in mathematical explicit manner. In comparison with existing explicit models in the literature which are valid exclusively for n2=n1 and n2=2n1, this model includes a wide range of silicon-based cells with arbitrary diodes ideality factors. Acquiring regulati...

در تعیین مناسبت کاربری اراضی شهری (urban land use suitability)کنونی به لحاظ دخیل بودن معیارهای مختلف، پیچیدگی (complexity) محیط پیرامون و عدم قطعیت uncertainty)) در اطلاعات به نظر می رسد استفاده از یک سیستم خبره مکانی فازی (spatial fuzzy expert system ) دارای انعطاف بیشتری نسبت به روشهای عددی مرسوم می باشد و هوش و نبوغ انسانی را در تصمیم گیریها بهتر منعکس کرده و نتایج مفیدی را در پی خواهد داشت....

Efficient management and prevention of species invasions requires accurate prediction of where species of concern can arrive and persist. Species distribution models provide one way to identify potentially suitable habitat by developing the relationship between climate variables and species occurrence data. However, these models when applied to freshwater invasions are complicated by two factor...
