The approximate average symbol error probability (ASEP) and outage probability (OP) of the multiple-mobile-relay-based mobile-to-mobile (M2M) cooperative systems with fixed-gain amplify-andforward (FAF) relaying and relay selection over N-Nakagami fading channels is investigated in this paper. The cumulative density function (CDF) of the signal-to-noise ratio (SNR) is used to derive the exact A...

It is of great mathematical significance and practical importance that the number of fiber intersections and uniformity within a unit area of a non-woven fiber web changes with the number and lengths of fibers as well as with aggregate length. The numerical relationships, while most important for imparting the desired physical and mechanical properties of the resulting fabric, are complex and n...

This study aims to undertake a statistical study to evaluate the accuracy of nine models that have been previously proposed for estimating the ultimate resistance of plate girders subjected to patch loading. For each model, mean errors and standard errors, as well as the probability of underestimating or overestimating patch load resistance, are estimated and the resultant values are compared o...

In surface reconstruction from slice samples (typical in medical imaging, coordinate measurement machines, stereolithography, etc.) the available methods attack the geometrical and topological aspects or a combinationof these. Topological methods classify the events occurred in the 2-manifold between two consecutive slices. Geometrical methods synthesize the surface based on local proximity of ...

The Raychaudhuri equation is derived by assuming geometric flow in space–time M of n+1 dimensions. turns into a harmonic oscillator form under suitable transformations. Thereby, relation between geometrical entropy and mean geodesic deviation established. This has connection to chaos theory where the trajectories diverge exponentially. We discuss its application cosmology black holes. Thus, we ...

in this study, geometrical, gravimetrical and frictional properties of four common varieties of iranian canola seeds (namely: slm, hyola, okapi, orient), containing the mean moisture value of 6.5% (w.b.) were investigated. geometrical and gravimetrical properties included length, diameter, geometric mean diameter, sphericity, thousand seed mass, volume, true density, bulk density and porosity. ...

We consider geometrical optimization problems related to optimizing the error probability in the presence of a Gaussian noise. One famous questions in the field is the “weak simplex conjecture”. We discuss possible approaches to it, and state related conjectures about the Gaussian measure, in particular, the conjecture about minimizing of the Gaussian measure of a simplex. We also consider anti...

The problem of blind separation of sources is generally solved by using statistical criteria, minimization of contrast function [2], [8], cancelation or minimization of a cost functions [6], [5], [4], [3]. However, using prior knowledge on the sources, new algorithms, basically simpler and more e cient, may be derived [9], [1], [7]. In this paper, assuming that sources have bounded probability ...

Based on the point of view of geometrical representation of an intuitionistic fuzzy set, we take into account all three parameters describing intuitionistic fuzzy set, propose a kind of new method to calculate correlation and correlation coefficient of intuitionistic fuzzy sets which is similar to the cosine of the intersectional angle in finite sets and probability space, respectively. Further...
