Suppose m and n are integers such that 1 ≤ m ≤ n. For a subgroup H of the symmetric group Sm of degree m, consider the generalized matrix function on m×m matrices B = (bij) defined by d(B) = ∑ σ∈H ∏m j=1 bjσ(j) and the generalized numerical range of an n×n complex matrix A associated with d defined by W(A) = {dH(X∗AX) : X is n×m such that X∗X = Im}. It is known that W(A) is convex if m = 1 or i...

Location management schemes presented in the personal communication network standards (e.g., EIA/TIA Interim Standard 41 (IS-41)) are not eecient. We propose forwarding techniques that augment the IS-41 scheme to provide eecient location management. We develop analytical models to compare the performance of the proposed approach with the IS-41 scheme. Analysis shows that forwarding signiicantly...

Suppose m and n are integers such that 1 m n, and H is a subgroup of the symmetric group S m of degree m. Deene the generalized matrix function associated with the principal character of the group H on an m m matrix B = (b ij) by d H (B) = X 2H m Y j=1 b j(j) ; and deene the generalized numerical range of an n n matrix A associated with d H by It is known that W H (A) is convex if m = 1 or if m...

This paper presents the complete algorithm of site response analysis of nonhomogeneous topographic structures using transient two-dimensional boundary element method (BEM). Seismic behaviour of various topographic features including canyon, half plane, sedimentary filled valley and ridge sections, subjected to incident SV and P waves are analysed. The analysis shows the efficiency of the propos...

introduction: asymptomatic diabetic patients are at increased risk of cardiovascular complications. myocardial perfusion scan may be effective in risk evaluation in this population. methods: 106 asymptomatic diabetic patients (age: min: 37, max: 82, mean: 57.73±8.88), including 56 females (52.8%) and 50 males (47.2%) were enrolled in the study. myocardial perfusion scintigraphy was performed by...
