A multi-step Richardson–Romberg extrapolation method for stochastic approximation

tight frame approximation for multi-frames and super-frames

در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...

A Stochastic Approximation Method for Reachability Computations

We develop a grid-based method for estimating the probability that the trajectories of a given stochastic system will eventually enter a certain target set during a –possibly infinite– look-ahead time horizon. The distinguishing feature of the proposed methodology is that it rests on the approximation of the solution to stochastic differential equations by using Markov chains. From an algorithm...

Extrapolation Method for Fuzzy Dierential Inclusions

A multi-step centrifuge method for extraction of leucocytes and preparation of Tc-HMPAO labeled leucocytes

Background: Labeled leucocytes could be used for localization of infection foci after surgeries or in inflammatory diseases including inflammatory bowel diseases. Extraction of leucocytes needs 10% Hetastarch which is not available in Iran. We provide a method employing multiple centrifuges to extract and label leucocytes with Tc-HMPAO. Methods: The study was conducted from April to June 2018 ...
