Abstract The frequency and severity of climatic extremes is expected to escalate in the future primarily because increasing greenhouse gas concentrations atmosphere. This study aims assess impact climate change on extreme temperature precipitation scenarios using indices Kashmir Himalaya. analysis has been carried out for twenty-first century under different representative concentration pathway...
InterWeave is a distributed middleware system that attempts to do for computer programs what the World Wide Web did for human beings: make it dramatically simpler to share information across the Internet. Specifically, InterWeave allows processes written in multiple languages, running on heterogeneous machines, to share arbitrary typed data structures as if they resided in local memory. In C, o...
Quantitative analysis of changes in Lhasa River runoff components was significant to local water resources management. This study constructed the spatial processes hydrology (SPHY) model Basin and optimized model’s parameters using hydrograph partitioning curves (HPC) method. The Basin’s precipitation temperature were forecasted for 2020 2100 statistical downscaling (SDSM) two scenarios from fi...
The analysis and visualization of weighted networks pose many challenges, which have led to the development of techniques for extracting the network’s backbone, a subgraph composed of only the most significant edges. Weighted edges are particularly common in bipartite projections (e.g. networks of coauthorship, co-attendance, co-sponsorship), which are often used as proxies for one-mode network...
Flood is one of the most calamitous natural disasters that causes extensive property and life damages across theworld. It however, could be a blessing due to its special natural water resources recharging value. By simulating themagnitude of probable floods considering the anthropogenic and natural effects and implementing contingency plans,their damages could be reduced. In this paper, the Gen...
Background and purpose: Jajrood River is one of the major drinking water supply rivers in Tehran, so, the effects of climate change on its quantitative and qualitative resources are highly important. This study aimed at investigating the effect of climate change on organic carbon removal in Jajrood basin. Materials and methods: In this descriptive cross-sectional study, CanESM2 general circula...
The agriculture sector in Africa is dominated by small-scale farmers who account for about 80% of the total farms. However, are vulnerable to climate change and variability. Their high susceptibility emanates from their inadequate ability adapt change. As a result, generally adversely impacted due over-reliance on rainfed natural resources. This exposure susceptibility, however, differ across r...
در این پژوهش نتایج سه مدل ریزمقیاسنمایی SDSM، شبکة عصبی ANN، و مدل مولد آبوهوایی LARS-WG در شبیهسازی پارامترهای اقلیمی بارش روزانه، کمینه، و بیشینة دمای روزانه در منطقة شمال غرب ایران مقایسه شده است. منطقة مورد مطالعه شامل دوازده ایستگاه هواشناسی است که دارای آمار بلندمدتاند. از دادههای دما و بارش روزانة ایستگاهها در دورة 1961 ـ 1990 به عنوان دورة پایه در مدل و دورة 1991 ـ 2001 به عنوان ...
Soil erosion is an increasingly issue worldwide, due to several factors including climate variations and humans’ activities, especially in Mediterranean ecosystems. Therefore, the aim of this paper is: (i) quantify predict soil rate for baseline period (2000–2013) a future (2014–2027), using Revised Universal Loss Equation (RUSLE) Water Assessment Tool (SWAT) model R’Dom watershed Morocco, base...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
