Methodology and Application of Meta-Diagnosis on Avionics Test Benches

This paper addresses Model Based Diagnosis for the test of avionics systems that combines aeronautic computers with simulation software. Just like the aircraft, those systems are complex since additional tools, equipments and simulation software are needed to be consistent with the test requirements. We propose a structural diagnostic framework based on the lattice concept to reduce the time of...

application of brand personality scale in automobile industry: the study of samand’s brand personality dimensions

این تحقیق شخصیت برند سمند را در ایران با استفاده از مدل پنج بعدی آکر (1997) بعنوان یک چهارچوب بطور توصیفی سنجیده است. بنابر این چهارچوب که دراصل در 42 جزء (42 ویزگی شخصیتی) ودر پنج بعد شخصیتی طراحی شده بود ودر کشورها وصنایع مختلف آزموده شده بود, پرسنامه به زبان فارسی ترجمه شده و با استفاده از روشهای ترجمه معکوس و مصاحبه عمیق با 12 متخصص ایرانی به 38 جزء کاهش یافت. و نظرسنجی ای در پنج نمایندگی ا...

Test Benches for Calibrating Custody Transfer Gas Meter

Several transmission and distribution companies in Western Europe operate test facilities for testing industrial meters like larger diaphragm gas meters, rotary gas meters and turbine gas meters. Alternatively, they lease mobile provers. Those installations are not suitable to perform the initial calibration (and try to save money on the calibration costs), but are suitable to perform all kind ...

On quasi-zero divisor graphs of non-commutative rings

Let $R$ be an associative ring with identity. A ring $R$ is called reversible if $ab=0$, then $ba=0$ for $a,bin R$. The quasi-zero-divisor graph of $R$, denoted by $Gamma^*(R)$ is an undirected graph with all nonzero zero-divisors of $R$ as vertex set and two distinct vertices $x$ and $y$ are adjacent if and only if there exists $0neq rin R setminus (mathrm{ann}(x) cup mathrm{ann}(y))$ such tha...
