in this article, the causative alternation in persian is discussed. first, it is shown that persian anticausative verbs involve a cause component and an implicit external argument. second, we claim that causative alternation arises when a single change-of-state verb invokes more than one semantic frame (fillmore, 1985): causative frame and anticausative frame. these semantic frames are the resu...

Abstract In this paper we consider the motion segmentation problem on sparse and unstructured datasets involving rigid motions, motivated by multibody structure from motion. particular, assume only two-frame correspondences as input without prior knowledge about trajectories. Inspired success of synchronization methods, address introducing a two-stage approach: first, is addressed image pairs i...

this study contains the identification of modal dynamic properties of a 3-story large-scale steel test frame structure through shaking table measurements. shaking table test is carried out to estimate the modal properties of the test frame such as natural frequencies, damping ratios and mode shapes. among many different model structures, arx (auto recursive exogenous) model structure is used fo...

dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

this paper deals with continuous frames and continuous riesz bases. we introduce continuous riesz bases and give some equivalent conditions for a continuous frame to be a continuous riesz basis. it is certainly possible for a continuous frame to have only one dual. such a continuous frame is called a riesz-type frame [13]. we show that a continuous frame is riesz-type if and only if it is a con...

رابطه‌­ی شدت ترمولومینسانس براساس مدل سینتیک مرتبه‌­ی اول بدون در نظرگرفتن اثر فروکشی دمایی مورد استفاده قرار می‌­گیرد. این حالی است که به عنوان یک واقعیت فیزیکی باید روابط بیان‌­کننده‌­ی توجه گیرد. کار با نظر گرفتن برای اول، تابع جداسازی منحنی تابش جدیدی برحسب و دمای قله دست آمد. نحوی جدید حذف مشخصه‌­های دمایی، همان قبلی خود تبدیل می‌­شود. دزیمتر (400TLD-) :Mn2CaF بررسی گرفت. این‌­که ­شدت طبق ...
