In this paper, we present a simple method to almost quadruple the spatial resolution of aliased images. From a set of four low resolution, undersampled and shifted images, a new image is constructed with almost twice the resolution in each dimension. The resulting image is aliasing-free. A small aliasing-free part of the frequency domain of the images is used to compute the exact subpixel shift...
در این پایان نامه روش های خطی عمومی (glms) را برای حل عددی معادلات انتگرال ولترا از نوع دوم که به صورت egin{equation*} y(t)=g(t)+int_{t_0 }^{t} k(t, au,y( au))d au , ;;;; tin[t_0 ,t] end{equation*} می باشد، بررسی می کنیم. رده ای از این روش ها را با مرتبه $p$ و مرتبه مرحله ای $q=p$ به کار می بریم. ویژگی مهم این رده از روش ها داشتن مرتبه بالا از مراحل داخلی است که از وزن های ا...
The quality of electron bunches accelerated by laser wakefields is highly dependant on the temporal and spatial features driver. Analysis experiments performed at APOLLON PW-class facility shows that instabilities focal spot, such as shot-to-shot pointing fluctuations or asymmetry transverse fluence, lead to charge energy degradation bunch. It shown PIC simulations can reproduce experimental re...
A practical compact antenna test range (CATR) requires good quiet zone quality for characterization. This paper addresses the phase profile of CATR from known intensity pattern spatial domain and Fourier based on a combined alternating projection algorithm. The proposed algorithm is composed Gerchberg–Saxton (GS) Hybrid Input–Output (HIO) algorithms two with perturbation (SPP) work collaborativ...
Weak geodesic flow on a semidirect product and global solutions to the periodic Hunter–Saxton system
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
Vinblastine is a powerful antitumor drug in widespread use in cancer chemotherapy. The mechanism by which vinblastine effects its unusually potent antiproliferative action is by inhibition of mitosis (Jordan et al., 1991), and often has been ascribed to its capacity to depolymerize mitotic spindle microtubules (e.g. Malawista et al., 1968; Wilson and Bryan, 1974). However, in recent studies we ...
