In this paper, we propose an optimal network selection technique for vertical handover. The proposed technique allows mobile users to select the best access network with seamless manner and to reduce the processing delay. Thus we aim to exploit the minimum of criteria which should be used for network selection. Our optimal network selection technique combines two multi attribute decision making...

Elastic Bunch Graph Matching has been proved effective for face recognition. But the recognition procedure needs large computation. Here we present an automatic face recognition method based on local feature analysis. The local features are firstly located by the face structure knowledge and gray level distribution information, rather than searching on the whole image as it does in Elastic Bunc...

The synthetic polyether polyethylene glycol (PEG) with a molecular weight of 20,000 was anaerobically degraded in enrichment cultures inoculated with mud of limnic and marine origins. Three strains (Gra PEG 1, Gra PEG 2, and Ko PEG 2) of rod-shaped, gram-negative, nonsporeforming, strictly anaerobic bacteria were isolated in mineral medium with PEG as the sole source of carbon and energy. All s...

Patients with glucocorticoid-remediable aldosteronism (GRA) possess a chimeric gene resulting from fusion of the genes encoding steroid aldosterone synthase and 11 beta-hydroxylase. In the adrenal zona fasciculata, this may lead to ectopic expression under ACTH control of aldosterone synthase activity and increased formation of cortisol C18 oxidation products. We assessed mineralocorticoid and ...

In this work, the authors have proposed a new technique for network selection decision. This technique combines two multi attribute decision making (MADM) methods. The analytic network process (ANP) method to find the differentiate weights of available networks by considering each criterion and the grey relational analysis (GRA) method to rank the alternatives. To show the effectiveness of our ...

The article presents a method for stock selection from the view of investors who contemplate stocks of a new investment. The AHP (Analytic Hierarchy Process) and Grey Relational Analysis are used as two integral parts of the method. By distilling information from the Judgment matrix, the AHP-GRA method provides a framework to assist investors in analyzing various investment factors, evaluating ...
