in 2005, a. abdollahi and a. rejali, studied the relations betweenparadoxical decomposition and configuration for semigroups. in thepresent paper, we introduce one other concept of amenability typeon semigroups and groups which includes amenability of semigroupsand inner-amenability of groups. we have extend the previous knownresults to semigroups and groups satisfying this concept.

We prove an exponential approximation for the law of approximate occurrence of typical patterns for a class of Gibssian sources on the lattice Z d , d ≥ 2. From this result, we deduce a law of large numbers and a large deviation result for the waiting time of distorted patterns. 1. Introduction. In recent years there has been growing interest in a detailed probabilistic analysis of pattern matc...

Time-sensitive networking (TSN) is an upcoming set of Ethernet standards designed for real-time and safety-critical Internet-of-Things (IoT) applications in automotive, aerospace, industrial automation domains. With the combination, complexity, flexibility flow control mechanisms TSN connected systems, performance analysis mixed-critical messages becoming a difficult challenge. The flexible win...

More studies are concentrating on using virtualization-based labs to facilitate computer or network learning concepts. Some benefits are lower hardware costs and greater flexibility in reconfiguring computer and network environments. However, few studies have investigated effective mechanisms for using virtualization fully for collaboration. Therefore, this study proposed one effective collabor...

Introduction: The different factors that affect the camera uniformity of Single Photon Emission Computed Tomography (SPECT) technique have been analyzed including peak shift (%) and window width of energy. The effect of peak shift and window width on SPECT image uniformity has been investigated using a point source to perform intrinsic flood images. Methods:</stro...

Duplex capillary columns with a packed and an open section are widely used in electrochromatography (CEC). The duplex column configuration leads to non-uniform voltage drop, electrical field distribution and separation performance. It also adds to the complexity in understanding and optimizing electrochromatographic process. In this study, we introduced a simplex column configuration based on s...

Introduction: In implantation, endometrial epithelium is affected by the release of steroid hormones secreted from the ovary and allows the blastocyst to bind. This course is called the “implantation window” and occurs about 4-10 days after the onset of progesterone secretion. Therefore, the endometrium undergoes changes in the configuration of microvilli in the apical membrane, as well as the ...

objective(s): the energy resolution of a cadmium-zinc-telluride (czt) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional anger type detector which is 10%. also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. in this study, we used a semiconductor detector and examined the ef...

Abstract Numerical simulations explore a possible tightly baffled, long-legged divertor (TBLLD) concept in future upgrade of the Tokamak à configuration variable (TCV). The SOLPS-ITER code package is used to compare exhaust performance several TBLLD configurations with results from unbaffled and baffled TCV configurations. investigated TBLLDs feature range radial gaps between separatrix baffles...
