This article details the design of six-port direct conversion front-end module for dual-band (1.575GHz and 2.680GHz) applications. Proposed planar architecture consists of single-stage (1:2) Wilkinson Power Divider and three numbers of quarter-wave 3-dB branch-line couplers working simultaneously at dual band of frequencies. Present article describes the designing of each building block and fin...

With the industrial demand caused by multi-sensor image fusion, infrared and visible fusion (IVIF) technology is flourishing. In recent years, scale decomposition methods have led trend for feature extraction. Such methods, however, low time efficiency. To address this issue, paper proposes a simple yet effective IVIF approach via feature-oriented dual-module complementary. Specifically, we ana...

let a be a banach algebra and e be a banach a-bimodule then s = a  e, the l1-direct sum of a and e becomes a module extension banach algebra when equipped with the algebras product (a; x):(a′; x′) = (aa′; a:x′ + x:a′). in this paper, we investigate △-amenability for these banach algebras and we show that for discrete inverse semigroup s with the set of idempotents es, the module extension bana...

let $r$ be a commutative ring with identity and $m$ be a finitely generated unital $r$-module. in this paper, first we give necessary and sufficient conditions that a finitely generated module to be a multiplication module. moreover, we investigate some conditions which imply that the module $m$ is the direct sum of some cyclic modules and free modules. then some properties of fitting ideals of...

a module $m$ is called $emph{h}$-cofinitely supplemented if for every cofinite submodule $e$ (i.e. $m/e$ is finitely generated) of $m$ there exists a direct summand $d$ of $m$ such that $m = e + x$ holds if and only if $m = d + x$, for every submodule $x$ of $m$. in this paper we study factors, direct summands and direct sums of $emph{h}$-cofinitely supplemented modules. let $m$ be an $emph{h}$...

Let R be a ring with identity, M right R-module and F fully invariant submodule of M. The concept an F-inverse split module has been investigated recently. In this paper, we approach to different perspective, that is, deal notion F-image M, study various properties obtain some characterizations kind modules. By means modules focus on in which submodules are dual Rickart direct summands. way, co...
