The Nyström sampling provides an efficient approach for large scale clustering problems, by generating a low-rank matrix approximation. However, existing sampling methods are limited by their accuracies and computing times. This paper proposes a scalable Nyström-based clustering algorithm with a new sampling procedure, Minimum Sum of Squared Similarities (MSSS). Here we provide a theoretical an...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
در گذشته تمرکز مطالعات دگرآسیبی بیشتر بر روی ارزیابی فعالیت سمیتی بقایای گیاهی و عصاره های آنها صورت می گرفت اما در سال های اخیر از طریق تاسیس و توسعه موسسه های علمی در سرتاسر جهان، پیشرفت های تکنیکی در زمینه این تحقیقات صورت گرفته و دانش دگرآسیبی طی دو دهه اخیر به علت ابداع روش های پیشرفته و همچنین همکاری بین دانشمندان و دستیابی به زیست آزمونهای مناسب، پیشرفت چشمگیری داشته است. از جمله روش های...
Most advancement in image de-noising algorithms are involving relatively poor numbers of patches and exploiting its similarity. These patch-based methods are completely based on matching of patches and their performance is restricted by the ability to dependably find suitably parallel patches. As number of patches grows, studies show that a point of retreating returns is reached where the perfo...
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
THE EFFECTIVE management of massive pulmonary embolism remains a challenge. The successful treatment rests primarily upon early operative intervention and survival without surgery is extremely low. In the series of sixty-five patients of Hampson, Milne & Small (1961) all but nine died immediately. Donaldson et al. (1963) reviewing 271 cases of massive pulmonary embolism, proved at autopsy, reve...
Several programming languages are beginning to integrate static and dynamic typing, including Racket, Microsoft’s C# 4.0 (Hejlsberg 2010) and TypeScript (Hejlsberg, 2012), Facebook’s PHP (Verlaguet, 2013), and the research languages Sage (Gronski, Knowles, Tomb, Freund, and Flanagan, 2006) and Thorn (Wrigstad, Eugster, Field, Nystrom, and Vitek, 2009). However, an important open question remain...
