This paper describes the application of a new fuzzy based control strategy to a three-phase shunt active power filter for harmonics minimization and reactive power compensation required by a variable non-linear load. To improve dynamic behaviour of shunt active power filter and make it robust under wide range of load variations, the value of load current is considered as an input of fuzzy contr...
There are situations in medical studies, wherein it is impossible to use the methods based on normal distribution (parametric methods). This paper objects to introduce common nonparametric methods and the inferences based on the methods in medical studies. Principles and method of calculations along with the software codes for common nonparametric methods and inference based on them were presen...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
چکیده: مقدمه:از زمانی که پرسلن لامینت ونیرها معرفی شده اند، محبوبیت آن ها افزایش یافته است. آماده سازی دندان با استفاده از این روش، محافظه کارانه بوده و همچنین این رستوریشن ها، زیبا می باشند؛ اگرچه بعضی از مطالعات مشکلاتی را از جمله عدم تطابق مارجین و failure load پایین را برای آن ها گزارش کرده اند. جهت ساخت لامینت تراش دندان باید در مینا باشد و عاج را در برنگیرد. در نتیجه محدودیت هایی درباره ...
in spite of their key role in various immunological processes occurring in the endometrium, t cells- especially + subtype- residing in this mucosal tissue, have not been extensively explored. we present here the profile of expressed genes for variable region of chain of t cell receptor (tcr) in normal endometrium as compared to peripheral blood. samples from endometrium were taken from norm...
Developable materials are ubiquitous in design and manufacturing. Unfortunately, general-purpose modeling tools are not suited to modeling 3D objects composed of developable parts. We propose an interactive tool to model such objects from a photograph. Users of our system load a single picture of the object they wish to model, which they annotate to indicate silhouettes and part boundaries. Ass...
High frequency force balance ~HFFB! measurements have recently been utilized to identify the distribution of spatiotemporally varying fluctuating wind loads on buildings. These developments, predicated on their ability to compute any response component of interest, based on actual building characteristics, attempt to offer a framework that eliminates the need for mode shape corrections generall...
In this paper we present a dynamic heuristics that allows for improving the performance of a parallel instantiator algorithm based on the DLV system. In this system, each rule is rewritten in several “splits” of the same size that are assigned to a number of parallel instatiator subprocesses. The new heuristics allows for dynamically determining an optimal amount of work that has to be assigned...
The release of arginine vasopressin (AVP) and atrial natriuretic hormone (ANH) and their involvement in renal water and electrolyte metabolism in primary aldosteronism in humans were studied. An oral acute water load (20 ml/kg body weight) was given to each of 12 patients before and after surgical removal of their aldosterone-producing adenoma(s). Plasma AVP and ANH were measured simultaneously...
