purpose: obesity is one of the most common problems in the world. imbalance between energy consumption and expenditure is a main factor in weight disorder. exercise helps losing weight by increasing energy expenditure and modulation of the energy intake. the present study examined protective effects of daily moderate aerobic exercise on preventing weight gain in high fat diet rats. materials an...

Currently, the existence of an extremal singly even self-dual code of length 24k + 10 is unknown for all nonnegative integers k. In this note, we study singly even self-dual [24k + 10, 12k + 5, 4k + 2] codes. We give some restrictions on the possible weight enumerators of singly even self-dual [24k + 10, 12k + 5, 4k + 2] codes with shadows of minimum weight at least 5 for k = 2, 3, 4, 5. We dis...

The purpose of this paper is to discuss the extent to which allowing for individuals to be indifferent among alternatives may alter the qualitative results that are obtained in social choice theory when domain restrictions are defined on profiles of linear orders. The general message is that indifferences require attention and careful treatment, because the translation of results from a world w...

closed families of sets. Poonen showed that if a finite union-closed family of sets S contains three of the 3−sets in some 4−set, then one of the elements of that 4−set is contained in at least half the members of the family S. This condition intrigued us, and we began to investigate collections of 3−sets for which it fails. The alternative statement that no 4−set contain more than two 3−sets i...

A non–linear diffusion equation is derived by taking into account hopping rates depending on the occupation of next neighbouring sites. There appears additonal repulsive and attractive forces leading to a changed local mobiltiy. The stationary and the time dependent behaviour of the system are studied based upon the master equation approach. Different to conventional diffusion it results a time...

We study a family of graph clustering problems where each cluster has to satisfy a certain local requirement. Formally, let μ be a function on the subsets of vertices of a graph G. In the (μ, p, q)-Partition problem, the task is to find a partition of the vertices into clusters where each cluster C satisfies the requirements that (1) at most q edges leave C and (2) μ(C) ≤ p. Our first result sh...

Abstract. A permutation is called layered if it consists of the disjoint union of substrings (layers) so that the entries decrease within each layer, and increase between the layers. We find the generating function for the number of permutations on n letters avoiding (1, 2, 3) and a layered permutation on k letters. In the most interesting case of two layers, the generating function depends onl...

PROPERTIES AND DEVICE APPLICATIONS OF SILICON AND SILICON-GERMANIUM NANOSTRUCTURES WITH DIFFERENT DIMENSIONS by Han-Yun Chang Defect-free crystalline Si/SiGe(Ge) nanostructures are demonstrated despite the 4% lattice mismatch between Si and Ge. The lattice mismatch-induced strain is sufficiently relaxed through the designed, cluster morphology, or nanowire (NW) structures. Future device applica...

ADAPTIVE DISTRIBUTED DETECTION WITH APPLICATIONS TO CELLULAR CDMA by Jian-Guo Chen Chair and Varshney have derived an optimal rule for fusing decisions based on the Bayesian criterion. To implement the rule, probabilities of detection PD and false alarm PF for each detector must be known, which is not readily available in practice. This dissertation presents an adaptive fusion model which estim...

Introduction. Let r be a bounded linear operator on a Banach space B and let t_1 exist. Consider a closed subspace C of B which is invariant under t, i.e. rCQC. The restriction of r to C is an operator T on the Banach space C. Suppose now that t^CÇ^C, so that T has no inverse. The class of operators T arising in this way has rather special properties, which are in general quite different from t...
