Social choice theory is concerned with collective decision making under different, possibly contrasting opinions and has been part of the core of society since ancient times. The goal is to implement some socially desired objective while at the same time accounting for the fact that people will act strategically, in order to manipulate the outcomes in their favor. In this thesis, we consider th...

In this paper, we obtain the Rényi entropy rate for irreducible-aperiodic Markov chains with countable state space, using the theory of countable nonnegative matrices. We also obtain the bound for the rate of Rényi entropy of an irreducible Markov chain. Finally, we show that the bound for the Rényi entropy rate is the Shannon entropy rate.

Communities can intuitively be defined as subsets of nodes of a graph with a dense structure. However, for mining such communities usually only structural aspects are taken into account. Typically, no concise and easily interpretable community description is provided. For tackling this issue, we focus on fast description-oriented community detection using subgroup discovery, cf. [1, 2]. In orde...

The additive algorithm was one of the early versions of the approach known as implicit enumeration or branch and bound. It solves a linear program in n 0-1 variables by systematically enumerating an (often small) subset of the 2” possible binary n-vectors, while using the logical implications of the 0-1 property to ensure that the whole set is implicitly examined.

this study was carried out to examine aflatoxin b1 (afb1) removal ability of four strains of lactic acidbacteria (lab). three indigenous (lactobacillus rhamnosus tmu094, lactobacillus fermentum tmu121and pedioccus pentosaceus tmu457) and a non-indigenous (labacillus rhamnosus ptcc1637) isolateswere studied. the strains were incubated with (afb1) at different time. the toxin residual in the supe...

encouraging an active lifestyle is an essential part of successful rehabilitation programs, and the link between physical activity and quality of life (qol) is well established among patients with mobility disorders. biomechanical aspects of wheelchair design play an important role in physical activity and social participation of disabled individuals. this review focuses on key biomechanical fe...

the sample population was consisted of 299 male and female students of the university of khwarizmi. theories used in this study included social bonding theory, differential opportunity, differential association, feeling anomie and frustration (love, and academic failure). the obtained results indicate that there is the bound variables, anomie, differential association, feeling of anomie, social...

An infeasible interior-point algorithm for mixed symmetric cone linear complementarity problems is proposed. Using the machinery of Euclidean Jordan algebras and Nesterov-Todd search direction, the convergence analysis of the algorithm is shown and proved. Moreover, we obtain a polynomial time complexity bound which matches the currently best known iteration bound for infeasible interior-point ...
