abstract this research has been carried out with the purpose of investigating the conditions and related elements of the employment of the educational sciences graduates of hamedan province universities in 1382-1387 academic years. it has been a descriptive research of a correlation kind, and the population number has been 1180 grduates of payam- e noor universites in asad – abaad, kaboudaraha...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
cognitive studies of translation process have recently been awarded a great deal of attention. there exists a psychological angle to almost all translation activities. the present study, thus, deals with analysing the relationships between iranian prospective translators tolerance for ambiguity (ta) and their willingness to translate (wtt). the research was conducted as a mixed methods study, d...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
هدف این پژوهش بررسی وضعیت فرایند بازاریابی براساس مدل چهارپی (4P) در کتابخانه های دانشگاهی شهر بیرجند است. پژوهش حاضر توصیفی – پیمایشی می باشد. جامعه آماری این پژوهش تا پایان دی ماه سال 1395، 50 نفر بوده است. ابزار گردآوری داده ها، پرسش نامه ای است که ضریب پایایی آن با استفاده از فرمول آلفای کرونباخ0/916 محاسبه شد. تجزیه و تحلیل داده ها با استفاده از نرم افزار SPSS نسخه 24 در دو سطح آمار توصی...
This paper presents a new nonlinear multivariate statistical process control technique for identifying and isolating the root cause of abnormal process behavior. The new technique is a nonlinear extension to the variables reconstruction technique by (Dunia et al., 1996), based on nonlinear principal component analysis (NLPCA). This work demonstrates that the variable reconstruction (i) affects ...
A strategy based on principal component analysis (PCA) is presented for detection, identification and reconstruction of faulty sensors. In this strategy, sensor fault detection is carried out by using multivariate statistics, faulty sensors are isolated using principal component score contributions and reconstruction of faulty sensors is accomplished through the analysis of fault direction vect...
Independent component analysis is a lively field of research and is being utilized for its potential in statistically independent separation of images. ICA based algorithms has been used to extract interference and mixed images and a very rapid developed statistical method during last few years. So, in this paper an efficient result oriented algorithm for ICA-based blind source separation has b...
Independent Component Analysis (ICA) is a useful extension of standard Principal Component Analysis (PCA). The ICA model is utilized mainly in blind separation of unknown source signals from their linear mixtures. In some applications, the mixture coeecients are totally unknown, while some knowledge about temporal model exists. In this paper, we propose a learning system for semi-blind binary s...
