در این طراحی توان مصرفی برابر p_dis=774?w، عددنویز معادل nf=0.93db، پارامتر های پراکندگی برابراند با s_11=-28.6db ، s_22=-17.6db ، s_21=28.2db و s_12=-64.6db ، بهره ولتاژ در خروجی معادل a_v=22.2db است و معیار خطینگی مدارiip_3=-12dbm و عدد شایستگی بدست آمده معادل fom=520?mw?^(-1) است.
Detection and localization performance with signal location uncertainty may be summarized by Figures of Merit (FOM’s) obtained from the LROC curve. We consider model observers that may be used to compute the two LROC FOM’s: ALROC and PCL, for emission tomographic MAP reconstruction. We address the case background-known-exactly (BKE) and signal known except for location. Model observers may be u...
While photocatalysis is considered a promising sustainable technology in the field of heterogeneous catalysis as well biocatalysis, figures merit (FOM) for comparing catalytic performance, especially between disciplines, are not established. Here, photocatalytic water splitting was conducted using semiconductor (NiO/La-NaTaO3) and bio-photocatalyst (Synechocystis sp. PCC 6803) same setup under ...
The design of unit cell metamaterial can tailor the permittivity and permeability. negative refractive index was achieved while real part permeability simultaneously or ? r ? i + < 0 conditions were satisfied, where , are permittivity, imaginary permeability, respectively. Currently, based on paper is a fascinating issue. Additional, used as dielectric due to its eco-friendly spacer. critical r...
Very small electromechanical coupling coefficient in micro-electromechanical systems (MEMS) or acoustic resonators is quite a concern for oscillator performance, specially at mmWave frequencies. This the manifestation of ratio motional capacitance to static resonators. work provides general solution overcome problem relatively high frequencies and presents analysis design techniques achieving e...
This paper presents a novel structure based on liquid crystal (LC) technology to achieve high figure of merit $(FOM)$ phase shifter that works at sub-6 notation="LaTeX">$GHz$ frequencies. The phase-shifting mechanism is enabled through the constant variation in main microstrip line, which loaded p...
We study the convergence of GMRES/FOM and QMR/BiCG methods for solving nonsymmetric Ax = b. We prove that given the results of a BiCG computation on Ax = b, we can obtain a matrix B with the same eigenvalues as A and a vector c such that the residual norms generated by a FOM computation on Bx = c are identical to those generated by the BiCG computations. Using a unitary equivalence for each of ...
An Israeli breeding line, BIZ, resistant to all four races of Fusarium oxysporum f.sp. melonis (FOM), has been characterized regarding its response to FOM race 1.2. The infection process of a FOM 1.2 strain that expresses the GFP reporter protein was monitored, suggesting the timing and sites in which fungal progression differs between a resistant and a susceptible genotype. A mapping populatio...
در این پایان نامه، به بررسی روش های مختلف جداسازی نوترون-گاما پرداخته شده است. روش های گذرازصفر و اوئن که بر اساس تبعیض شکل تپ (psd) عمل جداسازی را انجام می دهند و همچنین روش زمان پرواز که مبتنی بر زمان پرواز متفاوت نوترون و گاما بین دو نقطه در آزمایشگاه می باشد مورد آزمایش قرار گرفتند. آزمایش ها توسط چشمه am-be انجام شد و آشکارساز سوسوزن مایع به دلیل شکل خوب پالس و قابلیت بالای جداسازی نوترون...
