this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
During the past 50 years, a number of paradoxes have led to the downfall of expected utility theory as a viable description of decision making. Recently, rankdependent theories (e.g. cumulative prospect theory) have arisen as the ―leading‖ descriptive approach. A key component of these theories is the decision weight that reflects the importance of consequences when evaluating an action. Severa...
In this paper, we develop an aggregation procedure using time-varying weights for constructing the common component of international economic fluctuations. The methodology for deriving time-varying weights is based on some stylised features of the data documented in the paper. The model allows for a unified treatment of cyclical and seasonal fluctuations and also accommodates the dynamic propag...
همطالعه حاضر به ارائه مدلی برای آموزش موثر زبان انگلیسی می پردازد. مدل حاضر از سه عامل تاثیر گذار در کارایی تدریس معلمان زبان انگلیسی بهره می برد. این سه عامل شامل سبکهای اسنادی، خود تنطیمی و فرسودگی شغلی معلمان ایرانی زبان انگلیسی می باشد. رساله مورد نظر درچهار فاز طراحی شده است: فاز اول شامل طراحی و رواسازی پرسشنامه سبکهای اسنادی معلمان زبان انگلیسی و فاز دوم شامل استفاده از این پرسشنا...
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
The risk of forest and pasture fires is one the research topics interest around world. Applying precise strategies to prevent potential effects minimize occurrence such incidents requires modeling. This was conducted in city Sanandaj, which located west province Kurdistan Iran. In this study, fire assessed using weights evidence (WoE) statistical index (SI) models. Information about Sanandaj (2...
Background: It is critical to understand how accurately physicians can estimate the importance of each clinical finding in estimating the probability of a specific diagnosis in the process of clinical decision making. This study aimed to investigate whether physicians’ estimates of the importance of various clinical findings of ascites correlated with the positive likelihood ratios of the...
an adaptive input-output linearization method for general nonlinear systems is developed without using states of the system. another key feature of this structure is the fact that, it does not need model of the system. in this scheme, neurolinearizer has few weights, so it is practical in adaptive situations. online training of neurolinearizer is compared to model predictive recurrent training...
