Although traditional per-phase equivalent circuit has been widely used in steady-state analysis and design of induction motors, it is not appropriate to predict dynamic performance of the motor. In order to understand and analyze vector control of induction motors, the dynamic model is necessary. Unfortunately, the dynamic model equations are complex and there are many different forms of the mo...
Software systems with constrained and dynamic environments need to adapt to local and diverse computing environments by providing highly customized services at run-time. In order to address such dynamic changes effectively, composition models addressing complicated composition issues and supporting advanced composition features are required. In order to analyze and identify the required feature...
Dynamic panel data models include the important part of medicine, social and economic studies. Existence of the lagged dependent variable as an explanatory variable is a sensible trait of these models. The estimation problem of these models arises from the correlation between the lagged depended variable and the current disturbance. Recently, quantile regression to analyze dynamic pa...
This research aimed to investigate the relationships between psychological capital, learning empowerment, and dynamic interactions in students of Shahrood University of Medical Sciences. With regard to the ways data were collected, the present study is descriptive correlational and is specifically based on structural equitation modeling in which maximum likelihood estimation with adjusting skew...
In order for dynamic circuits to operate correctly, their inputs must be mono-tonically rising during evaluation. Blocking dynamic circuits satisfy this constraint by delaying evaluation until all inputs have been properly setup relative to the evaluation clock. By viewing dynamic gates as latches, we demonstrate that the optimal delay of a blocking dynamic gate may occur when the setup time is...
Purpose: of the most critical changes in the elderly is the weakness in keeping their balance that can expose them to severe injury risks. The purpose of this study was to evaluate the effects of 8 weeks of strength, balance, and combined (strength and balance) training programs on the dynamic and static balance of inactive older men. Methods: Forty older men, who were the members of Robat Kar...
Hedging the risk of crude oil prices fluctuation for countries such as Iran that are highly dependent on oil export earnings is one of the important subject to discuss. In this regard, the main purpose of this study is to calculate and analyze the optimal dynamic hedging ratio for Iranian light and heavy crude oil spot prices based on one-month to four-month cross hedge contracts in New York St...
To control the exponential growth of malware files, security analysts pursue dynamic approaches that automatically identify and analyze malicious software samples. Obfuscation and polymorphism employed by malwares make it difficult for signature-based systems to detect sophisticated malware files. The dynamic analysis or run-time behavior provides a better technique to identify the threat. In t...
Investigating connections between financial and oil markets is important for investors and policy makers. This knowledge allows for appropriate decision making. In this paper, we measure the dynamic connections of selected stock markets in the Middle East with oil markets, gold, dollar index and euro-dollar and pound-dollar exchange rates during the period February 2007 to August 2019 in networ...
In the stadium structure, the significant dynamic responses such as resonance or similar behavior can be occurred by spectator rhythmical activities. Thus, accurate analysis and precise investigation of stadium structure that is subjected to dynamic loads are required for practical design and serviceability check of stadium structures. Moreover, it is desirable to measure and analyze the dynami...
