in this paper, we nd the relationships between module contractibility of abanach algebra and its ideals. we also prove that module contractibility ofa banach algebra is equivalent to module contractibility of its module uniti-zation. finally, we show that when a maximal group homomorphic image ofan inverse semigroup s with the set of idempotents e is nite, the moduleprojective tensor product ...

let r be a ring, m a right r-module and (s,≤) a strictly ordered monoid. in this paper we will show that if (s,≤) is a strictly ordered monoid satisfying the condition that 0 ≤ s for all s ∈ s, then the module [[ms,≤]] of generalized power series is a uniserial right [[rs,≤]] ]]-module if and only if m is a simple right r-module and s is a chain monoid.

Let $A$ be a Banach algebra and $E$ be a Banach $A$-bimodule then $S = A oplus E$, the $l^1$-direct sum of $A$ and $E$ becomes a module extension Banach algebra when equipped with the algebras product $(a,x).(a^prime,x^prime)= (aa^prime, a.x^prime+ x.a^prime)$. In this paper, we investigate $triangle$-amenability for these Banach algebras and we show that for discrete inverse semigroup $S$ with...

the concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. the notion of free fuzzy modules was introducedby muganda as an extension of free modules in the fuzzy context. zahedi and ameriintroduced the concept of projective and injective l-modules. in this paper we give analternate definition for projective l-modules. we prove that e...

Abstract Aiming at the disadvantage of high-power consumption and a long start-up time traditional Pearce driver circuit, 32.768KHz crystal circuit is designed, which can effectively reduce power ensure fast start. The simulation results show that, under voltage 1.1 V, vibration 0.5 ms, output amplitude about 250 mV, static current 48.6 nA, 53.5nW. This drive has characteristics start, stable o...

For potatoes, a crop with specific plant spacing and large row spacing, continuous spray has problems including low spraying accuracy washability. In order to improve the utilisation of this crop, manuscript designed targeted variable sprayer. To ensure that function is achieved, design verification vehicle body targeting device sprayer were carried out. guarantee automation precision are impro...

The purpose of this research was to determine the performance AZO and MCCO materials as constituents thin film-thermoelectric generator module. method used for fabrication is DC Magnetron Sputtering. electrode material Ag substrate SiO2 glass. arrangement film thermoelectric module P-N-P-N-P-N-P-N-P-N (5 couples p-n junctions). Based on test results, thickness type N 74.72 nm P 90.34 nm. At hig...

 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 o...
