Katener sistemi hesaplamalarında girdileri oluşturan coğrafi ve iklimsel değişkenlerin kontrolü elimizde değildir. Ancak doğru hesaplamalar sonucu elde edilecek bulgular ile sistemin daha güvenli konforlu çalışmasını mümkün kılmak elimizdedir. Çevresel koşulların katener üzerindeki etkisi iyi bir şekilde incelenmesi takdirde olası arızalarını önleme, maliyet analizi yapabilme tasarım imkanların...

let $r$ be a ring and $m$ a right $r$-module with $s=end_r(m)$. a module $m$ is called semi-projective if for any epimorphism $f:mrightarrow n$, where $n$ is a submodule of $m$, and for any homomorphism $g: mrightarrow n$, there exists $h:mrightarrow m$ such that $fh=g$. in this paper, we study sgq-projective and$pi$-semi-projective modules as two generalizations of semi-projective modules. a m...

let $r$ be a commutative ring with identity and $m$ be a unitary$r$-module. the primary-like spectrum $spec_l(m)$ is thecollection of all primary-like submodules $q$ such that $m/q$ is aprimeful $r$-module. here, $m$ is defined to be rsp if $rad(q)$ isa prime submodule for all $qin spec_l(m)$. this class containsthe family of multiplication modules properly. the purpose of thispaper is to intro...

In the present paper, the concepts of module (uniform) approximate amenability and contractibility of Banach algebras that are modules over another Banach algebra, are introduced. The general theory is developed and some hereditary properties are given. In analogy with the Banach algebraic approximate amenability, it is shown that module approximate amenability and contractibility are the same ...

Pantograph-catenary system provides electric energy for the subway lines; its health status is essential to serviceability of vehicle. In this study, a real-time structural monitoring method based on strain response inversion proposed calculate magnitude and position dynamic contact force between catenary pantograph. The measurement principle, calibration, installation detail fiber Bragg gratin...
