Wind is the world’s fastest growing electric energy source. Because it is intermittent, though, wind is not used to supply baseload electric power today. Interconnecting wind farms through the transmission grid is a simple and effective way of reducing deliverable wind power swings caused by wind intermittency. As more farms are interconnected in an array, wind speed correlation among sites dec...
Dust storms and high winds is a natural process that occurs in everywhere of arid and semi-arid land in the world. The phenomenon of dust is one of the most important consequences of the desertification that cause different damages. The aim of this study was to analyze the occurrence of dust in the city of Bandar Abbas. First, the frequency of monthly and annual dust from 1985-2005, in the city...
The Long-Term Inflow and Structural Test (LIST) program is gathering inflow and structural response data on a Westinghouse 600-kW wind turbine located at a test site near Boulder, Colorado. Data from 1043 ten-minute time segments are analyzed here to determine the dependency of fatigue and extreme loads on inflow parameters. Flap and edge bending moment ranges at the blade root are studied as t...
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
The present studies were aimed to evaluate 490 maize entries for resistance against turcicum leaf blight (TLB) disease in randomized block design using a check at Agricultural Research Station, Karimnagar, Telangana State, India during rabi (November,2021 Febrauary,2022) and kharif (July,2022 October,2022). Out of 213 lines 2021−2022,16 promising viz.,KML-21,KML-24,KML-33,KMH-388,KMH-275,KMH-37...
Introduction: The present study aimed to investigate the change of air pollutants in 2020 in Qom compared to the same period in 2019 in five scenarios. Materials and Methods: The hourly air quality data was obtained from air quality monitoring stations of Qom Environmental Protection Organization (EPO). The meteorological parameters were obtained from Iranian Meteorological Organization websi...
as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...
Dust uplift is a nonlinear thresholded function of wind speed and therefore particularly sensitive to the long tails of observed wind speed probability density functions. This suggests that a few rare high-wind events can contribute substantially to annual dust emission. Here we quantify the relative roles of different wind speeds to dust-generating winds using surface synoptic observations of ...
since the emergence of human civilization, drought has had extreme and sometimes catastrophic effects on human livelihoods. although drought itself is not a disaster, its impact on people and the environment may sometimes yield disastrous consequences; so a primary requirement is to better understand the natural and social dimensions associated with drought (wilhite 2000). given that drought i...
