In this paper we describe routing functions for optical packets in point-to-point networks. These functions are based on Eulerian tours. We first define different measures to handle the efficiency of this routing. Then, we describe an algorithm to compute these measures. Moreover, we present such an Eulerian routing in the Square Mesh and we prove that the induced paths are close to the optimal...

Much research in recent years has focused on various routing strategies for supporting ee-cient communication in point-to-point networks. Other research has emphasized novel switching techniques, such as virtual cut-through and wormhole switching. However, little attention has been paid to the subtle interplay between routing and switching schemes. It is desirable to select routing strategies t...

Here we consider approaches to the ranking of fuzzy numbers based upon the idea of associating with a fuzzy number a scalar value, its signal/noise ratios, where the signal and the noise are defined as the middle-point and the spread of each $gamma$-cut of a fuzzy number, respectively. We use the value of a as the weight of the signal/noise ratio of each $gamma$-cut of a fuzzy number to calcula...

One-dimensional cut-and-project point sets obtained from the square lattice in the plane are considered from a unifying point of view and in the perspective of aperiodic wavelet constructions. We successively examine their geometrical aspects, combinato-rial properties from the point of view of the theory of languages, and self-similarity with algebraic scaling factor θ. We explain the relation...

Body iron levels have recently been shown to be a strong predictor for non-alcoholic fatty liver disease (NAFLD). The aims of this study were to investigate the prevalence of NAFLD in a general adult population, and to investigate the relationship between body iron levels, NAFLD and the metabolic syndrome (MetS). 2186 adults participated in the third National Nutrition and Health Survey in Taiw...

A continuous curve M will be said to be a two-way continuous curve, or to be "two-way continuous," provided it is true that between every two points of M there exist in M at least two arcs neither of which is a subset of the other. A point P of a continuum M is a cut point of M provided it is true that the point set M—P is not connected. Every point of a continuum M which is not a cut point of ...

the aim of this study was to evaluate the psychometric properties, factor structure and kessler psychological distress scale (k-10) cut-off point on the students and prepare it as a screening tool for mental health. in this study, 500 students of tehran universities of medical sciences were selected by proportional sampling. participants responded to the kessler psychological distress scale and...

background: two questions about diagnostic value of urinary neutrophil gelatin associated lipocalin (ungal) in detection of acute kidney injury (aki) in children have remained unanswered; first, which cut-off point of ungal has the highest value in detection of aki; and second when is the best time for measuring this biomarker in a patient? accordingly, the present study aimed to conduct a syst...
