The main purpose of this study is to provide three simulation-based risk management models for optimal placement of wind turbines in Khodabandeh city (located in the south of Zanjan province) taking into account the wake effect and uncertainty in wind speed and direction. For this purpose, wind speed and direction data were collected, then wind speed and direction uncertainty was modeled by Mon...
Wind Power generation integrated in electrical power system can cause of variation and uncertainty which must be considered in process of generation expansion planning (GEP). The goal of this study is to model the GEP problem integrated with wind power generation and introduce the fuzzy-probability model to consider variation and uncertainty of wind power generation. To verify and optimize the ...
The result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. The Khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of Dasht-e-kavir. It is evident that the ecosystem balance of t...
With the relocation of the Fatimid caliphate to Egypt during the Islamic Middle ages, Iranian agents who were active in da'wa (invitation) organization as the religious rank of Dā'ī al-Du'āt and Hojjat (proof), started to promote and propagate inside and outside of the territory. Through scientific contribution in distribution and consolidating Fatimid’s religious and political power, Iranian d...
air pollution is a problem in kathmandu, nepal. particulate matter concentrations often exceed threshold values at which human health is severely affected. the problem is serious since it is in the valley topography wherein the meteorological parameters role is significant. this study addresses the linkages between meteorological processes and air pollution in the lower atmosphere of the kathma...
Giant-cell arteritis (GCA) has been considered a paradigm of glucocorticoid-responsive disease because the majority of patients experience substantial relief of their symptoms with high-dose glucocorticoids (GC). However, GC may not completely suppress crucial immunopathogenic pathways, eventually leading to disease recurrence1,2. GCA has been largely recognized as a relapsing disease. However,...
the shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. in reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a s-shape profile. the pr...
wind regime and sand grain size are two of the factors that determine the morphology and dynamics of sand dunes in desert areas. regarding the importance of wind effects on sand dunes especially in iran, in this study, khartooran erg was analyzed to determine wind direction and to detect sand source sites. khartooran erg is located on eastern north of iran and lies in khorasan razavi and semnan...
Soil erosion by wind is a widespread problem in the arid lands of Iran. This research estimated and assessed the severity of wind erosion in Segzi desertification hotspot located in the eastern part of Isfahan township, focusing on criteria used in the IRIRF (Iranian Research Institute of Forest and Rangelands) model. Bayesian belief networks (BBNs) were also used to convert the IRIFR model to ...
In recent years, wind energy has a remarkable growth in the world, but one of the important problems of power generated from wind is its uncertainty and corresponding power. For solving this problem, some approaches have been presented. Recently, the Artificial Neural Networks (ANN) as a heuristic method has more applications for this propose. In this paper, short-term (1 hour) and mid-term (24...
