abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
control of three phase inverters has been an important issue in recent years. this paper proposes active disturbance rejection control (adrc) scheme for controlling three phase inverters. the main advantage of adrc that motivated us for using this controller for inverter is that it is model independent. this controller is used in a double loop structure including an inner current loop and oute...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
abstract english language learning in iran has become significant in recent years, and english has been included in the curriculum of iranian schools and universities, and considerable attention has been paid to this language in our society. nevertheless, teaching and learning english in iranian schools has not been able to satisfy the specified goals, so different efl institutes have been est...
abstract in recent years, many researchers have attempted to estimate the soil hydraulic functions (e.g. soil moisture characteristics curve, and hydraulic conductivity function) using particle-size distribution (psd) curve. in these studies, an accurate mathematical representation of psd is required for fitting the observed data. so far, some mathematical models were developed with different l...
background: the present study aims to evaluate the cost-effectiveness of dynamic interspinous spacer (coflex®) and static spacer (x-stop ®) compared to laminectomy (lami) in patients with lumbar spinal stenosis. methods: a decision-analysis model was developed to estimate the cost-effectiveness. the effectiveness parameters were obtained from a systematic literature review in relevant databas...
methodology non-native participants in this study were sixty ba students majoring in english literature and teaching english as a foreign language at khayyam university of mashhad. they were senior students, between 21 to 24 years old, who had studied english for at least three and a half years and had passed several courses including grammar, reading, conversation, and writing. this was assum...
Introduction Selection the appropriate statistical model for the response variable is one of the most important problem in the finite mixture of generalized linear models. One of the distributions which it has a problem in a finite mixture of semi-parametric generalized statistical models, is the Poisson distribution. In this paper, to overcome over dispersion and computational burden, finite ...
background: routine reporting of sexually transmitted infections (stis) in iran is one of the main information sources on stis, endures some diminution under influence of several factors. we aimed to adjust registered sti data with a model-based approach and estimate the incidence and prevalence of stis in iran. methods: in this cross-sectional study, we developed a stochastic compartmental mod...
The optimal barbell trajectory for snatch weightlifting has been achieved empirically by several researchers. They have studied the differences between the elite weightlifters’ movement patterns and suggested three optimal barbell trajectories (type A, B, and C). But they didn’t agree for introducing the best trajectory. One of the reasons is this idea that the selected criterion by researchers...
