Let $R$ be a ring, $sigma$ be an endomorphism of $R$ and $M_R$ be a $sigma$-rigid module. A module $M_R$ is called quasi-Baer if the right annihilator of a principal submodule of $R$ is generated by an idempotent. It is shown that an $R$-module $M_R$ is a quasi-Baer module if and only if $M[[x]]$ is a quasi-Baer module over the skew power series ring $R[[x,sigma]]$.
This paper qualifies the effect of different convection schemes and center-domains on the simulation of winter precipitation over Iran using RegCM3 numerical climate model. It is compressible, finite difference with hydrostatic equilibrium in sigma coordinate with a semi-implicit algorithm for reduction of horizontal diffusion. Iran experienced two dry and wet periods during winters of 1997 and...
Introduction: The competitive condition of the world is such that the organizations make quality improvement, increase customers' satisfaction, reduce costs and increase productivity. Existence of such environment cause the variety technique and approaches such as total quality management, re-engineering, value engineering, lean production and Six Sigma. Six Sigma as the newest program of quali...
Intrudaction: Conspicuous achievements of organization with minimum facilities on one hand and failure of organizations with materialist abilities on the other hand have been shown the considerable role of factors including non-materialist and spiritual in their success. Organizational culture would be considered as an effective factor in organization performance. correlation of organization's ...
Background: Clinical application of the test results are profoundly influenced by laboratory errors. Nowadays, the best way to evaluate the performance of a method is to determine its sigma scale according to total allowable error (TEa) and analytical errors, including random and systematic errors. In this study, the performance of the measuring kits for biochemical analytes belonging to Pars A...
Background and Aims: Six sigma is the latest version of total quality management. It is quantitative goal for process performance. With increasing demands for improved accuracy and reliability of the results, Six Sigma is gaining increased visibility in the clinical laboratory process outcomes. The aim of study was to evaluate the quality of analytical phase performance in a clinical biochemist...
فرایند six sigma یکی از دست آوردهای مهم نظام مدیریت کیفیت جامع است که به طور فزاینده ای در شرکت های معتبر و موفق دنیا به کار گرفته شده است. این فرایند با تکیه بر اهداف زیر عمل میکند: ۱- رضایت مشتری ۲- تولید با خطای تقریبا صفر 3- صرفه جویی در منابع4- بازگشت سرمایه 5- نهادینه کردن کیفیت در سازمان 6-بهبود مستمر و حفظ فرایند بهبود شش زیگما به عنوان نوعی ابزار عملی قابل سنجش و تحلیل هوشمند، این امکا...
We find a class of five-dimensional Einstein-Maxwell type Lagrangians which contains the bosonic Lagrangians of vector multiplets as a subclass, and preserves some features of supersymmetry, namely the existence of multi-centered black hole solutions and of attractor equations. Solutions can be expressed in terms of harmonic functions through a set of algebraic equations. The geometry underlyin...
در این رساله به بررسی کران داری ضربگرهای لامبرت با برد عملگرهای ترکیبی روی فضاهای $l^p(sigma)$ می پردازیم. بر این اساس، برخی از ویژگی های عملگرهای امید شرطی را نسبت به زیرجبرهای $sigma$ از نوع صفر بررسی می کنیم. همچنین، به مطالعه ی عملگر ترکیبی وزن دار روی فضای فرم های دیفرانسیل اندازه پذیر می پردازیم. به علاوه، بعضی خواص این عملگرها مانند کران داری، تعلق به کلاس های به طور ضعیف ن...
Abstract The elliptic algebras in the title are connected graded $\mathbb {C}$ -algebras, denoted $Q_{n,k}(E,\tau )$ , depending on a pair of relatively prime integers $n>k\ge 1$ an curve E and point $\tau \in E$ . This paper examines canonical homomorphism from to twisted homogeneous coordinate ring $B(X_{n/k},\sigma ',\mathcal {L}^{\prime }_{n/k})$ characteristic variety $X_{n/k}$ for When...
