در این پژوهش نگاشتهای حافظ تعامد وحافظ تعامد تقریبی را در دستگاههای *c- مدولها ی ضرب داخلی مورد مطالعه قرار داده ایم. به ویژه اگر a ،v,w- مدولهای ضرب داخلی روی *c-جبر a باشند و این مطلب که هر مضرب اسکالر از یک طولپای a-خطی ، یک نگاشت حافظ تعامد است، که البته عکس این مطلب به طور کلی برقرار نیست. مگر این که a شامل (c*) k(h -جبری از همه ی عملگرهای فشرده روی فضای هیلبرت h) باشد. علاوه براین تخمینی...
This paper describes the design, computational aspects and implementation of an iterative technique for measuring power system frequency. The technique provides accurate estimates to a resolution of 0.01-0.02 Hz for near-nominal, nominal and off-nominal frequencies in about 20 ms. Computation requirements are modest and the technique has been implemented on a modern digital signal processor. Th...
In sub-65nm CMOS technology, switching power and gate as well as subthreshold leakage power are the major components of total power dissipation. To achieve power-performance tradeoffs one varies different process (Tox, K, Vth,) and design parameters (VDD, W). Techniques for (i) dual-K and dual-Tox have been proposed to reduce gate leakage, (ii) dual (multiple)-Vth has been introduced to minimiz...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
A power amplifier structure is presented that has a low output variation against the load impedance at 6.78 MHz using two Class E amplifiers and λ/4 transmission line. with another high are connected in parallel phase difference of 90° Each generates same under nominal conditions to achieve maximum efficiency. The can be reduced during operation, which increases from one decreases time when cha...
In the last years, use of wind turbines for power generation has increase due to advance's technology used and stable cost. this paper, low investment in desert regions Fezouata, Ouijjane, El Ouatia, Taroudannt Morocco, we have considered resources as an ideal option. Using meteorological statistics, Weibull's distribution function was able estimate potential four various each site with nominal...
Bradley A. Minch, Chris Diorio, Paul Hasler, Carver Mead Computation and Neural Systems California Institute of Technology Pasadena, CA 91125 (818) 395-6996 [email protected] ABSTRACT In this paper, we describe a novel circuit consisting of N + 1 MOS transistors and a single oating gate which computes a soft maximumof N current inputs and re ects the result in the output transistor. An in...
the present thesis is a study of postmodern historical novel with respect to the voice of women. according to postmodern historiography,the established institution of history is one of the other manifestations of patriarchys power which has silenced women. the study analyzes angela carters nights at the circus as a postmodern historical novel which makes its female characters transgress the pat...
A 250 kW / 5 kWh engineering prototype Flywheel Energy Storage System (FESS) was designed, fabricated and component tested by Adelwitz Technologiezentrum GmbH (ATZ) and L-3 Communications Magnet Motor GmbH (MM). A heavy – load vertical 0.6 ton rotor is suspended totally magnetically by an HTS radial-passive bearing on the top together with a PM bearing at the bottom. Further features are the fl...
Wind energy is used to rotate a magnetic turbine in order to remove heat from the surface of a photovoltaic (PV) panel. A three-bladed turbine, which rotates with wind energy, has rotational motion underneath the studied PV panel in order to move Magnetic Nano-Particles (MNPs). In addition, effects of the magnetic field strength (B=450-830 mT), rotational velocity of the magnetic turbine (ω), a...
