It is recently shown in [1, 2] that the exact analytical solution of a rigid body controlled by a linear feedback law may directly be written down in terms of eigenvalues and eigenvectors. However, this control has been computed in previous work [3] for the regulation of satellite angular momentum when the flywheels are at rest. Therefore, the method will here be extended to deal with the struc...
کشف ابر تقارن یکی از اهداف اصلی lhc، برخورد دهنده هادرونی بزرگ ساخته شده در cern است. در اینجا یک سناریوی بسیار مقید را در نظر می گیریم که گرانش، مسئول اصلی شکست ابر تقارن می باشد. توانایی cms برای پیدا کردن ابرتقارن با جرم کم در رویدادهایی با یک کوارک سر در حالت نهایی، به وسیله شبیه سازی مطالعه شده است. یک برازش جنبشی با دو قید برای استخراج کوارک سر برای هر دو حالتی که جت b قابل شناسایی باشد ی...
Safflower (Carthamus tinctoius L.) is an Iranian native crop that is adapted to different environmental conditions of this country. Sixteen safflower varieties/lines were spring-planted in 6 research stations including Sararood (Kermanshah), Maragheh, Ghamlo (Kordestan), Khodabandeh (Zanjan), Shirvan (North Khorasan)and Khohdasht (Lorestan) with and without drought stress conditions each in a R...
The design of dual axis microengineered comb-drive electrostatic actuators is investigated. Experimental measurements of diode-isolated bulk micromachined x–y stages with a folded, single-flexure suspension show the presence of unwanted two-dimensional vibrational mode patterns. A combination of coupled-mode and finite-element analysis is used to explain the existence of the spurious modes, and...
In this paper, a recently suggested general procedure which leads to an eigenvahre eqnation for apertnre problems is specialized to the range of frequencies for which the maximnm linear dimension of the aperture [ is much smaller than the wavelengths, known as the Rayleigh region. As kl asymptotically approaches zero, we arrive at a set of two eigenvahre equations which aided by the edge condit...
Colistin, also known as polymyxin E, a polymyxin antibiotic, comprised of colistin E1 and colistin E2, has good inhibitory effect for pathogen infection [1,2]. The characteristic lariat structure of colistin E1 was proven necessary for antimicrobial activity [3]. Since the sulfate polymyxin compounds were separated from different types of bacillus polymyxa in 1947, they have been tested by vitr...
An iterative algorithm is adopted to construct approximate representations of matrices describing the scattering properties arbitrary objects. The method based on implicit evaluation responses from iteratively generated excitations. does not require explicit knowledge any system (e.g., stiffness or impedance matrices) and well-suited for use with matrix-free full-wave solvers, such as FDTD, FEM...
