Research ArticleOpen accessIn the author namesAnalysis of Trends in Daily and Overnight Temperature Over Iran's Zayanderud River BasinAli Zahraei, Sara Saadati, Saeid Eslamian, Kaveh Ostad-Ali-AskariDaily and overnight temperature trends in annual time-scale for Zayanderud river basin using 37 meteorological stations were studied. According to the results the majority of trends in the time series of daily and overnight temperature were increasing. Warming trends in the overnight temperature were stronger than those in the daily temperature. The average of all stations in the daily and … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 4 Aug 2020 · 6,960 accessesView PDFCite
Research ArticleOpen accessIn the author namesSolutions to Managing Drought and Reducing DemandsSaeid Eslamian, Saleh Tarkesh Esfahani, Kaveh Ostad-Ali-AskariConserving and saving water during droughts need a special attitude and great attention. Because according to a variety of studies conducted, nowadays our demand and need for water far exceed the amount of water resources available in different areas. As a result, in order to cope with this crisis, it is necessary to use water-recycling systems, reduce demands, employ optimal … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 29 Jul 2020 · 6,973 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Multiple Tuned Mass Damper for Passive Control of Structures by Cuckoo AlgorithmHamid Jafari Nia, Amir Hossein Heidari, Hamid Reza Babaali, Kaveh Ostad-Ali-AskariAdjustable mass dampers are recently used to reduce seismic vibrations of engineering structures. Function of these types of systems requires a suitable setting of their parameters. In this study, a practical method to design Multiple Tuned Mass Dampers (MTMD) has been proposed to minimize the maximum displacement of roof, acceleration of roof and TMDs displacement to reduce the seismic response … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 16 Jul 2020 · 7,392 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvolutionary Structural Optimization of Wind Bracing Connection Plates in Steel StructuresReza Kasiri, Saeid Eslamian, Theodore C. Crusberg et al.Evolutionary Structural Optimization (ESO) is one of the rules in structural engineering which has received much attention by the researchers.
