Dealing with network congestion is a criterion used to enhance quality of service (QoS) in distributed multimedia systems. The existing solutions for the problem of network congestion ignore scalability considerations because they maintain a separate classification for each video stream. In this paper, we propose a new method allowing to control QoS provided to clients according to the network ...

The short-distance Hamiltonian describing b → s(d)e−e+ in the standard model is used to obtain the decay spectrum of B̄ → K−π+e−e+ and B̄ → π−π+e−e+, assuming the Kπ and ππ systems to be the decay products of K and ρ respectively. Specific features calculated are (i) angular distribution of K (or π) in the K−π+ (or π−π+) centre-of-mass (c.m.) frame; (ii) angular E-mail address: [email protected]....

in this paper we introduce and study besselian $g$-frames. we show that the kernel of associated synthesis operator for a besselian $g$-frame is finite dimensional. we also introduce $alpha$-dual of a $g$-frame and we get some results when we use the hilbert-schmidt norm for the members of a $g$-frame in a finite dimensional hilbert space.

In this paper a new cooperative transmission scheme is proposed that enjoys some important advantages over similar protocols First it achieves cooperative diversity without relying on orthogonal subspaces e g di erent spreading codes or frequency bands allowing full rate transmission Second its performance degrades gracefully as the path loss between cooperating partners increases never falling...

Title of dissertation: GABOR FRAMES FOR QUASICRYSTALS AND K-THEORY Michael Kreisel, Doctor of Philosophy, 2015 Dissertation directed by: Professor Jonathan Rosenberg Department of Mathematics We study the connection between Gabor frames for quasicrystals, the topology of the hull ΩΛ of a quasicrystal Λ and the K-theory of an associated twisted groupoid algebra. In particular, we construct a fin...

We investigate the Butcher-Oemler effect using samples of galaxies brighter than observed frame K * + 1.5 in 33 clusters at 0.1 z 0.9. We attempt to duplicate as closely as possible the methodology of Butcher & Oemler. Apart from selecting in the K-band, the most important difference is that we use a brightness limit fixed at 1.5 magnitudes below an observed frame K – 2 – the nominal limit of r...

In this work, we describe a Frenet frame in 4-dimensional Euclidean space and call as parallel transport (PTF). PTF is an alternative approach to defining moving frame. This obtained by rotating the tangent vector first binormal of unit speed curve euler angle then give curvature functions according curve. Also, introduce $(k,m)$-type slant helices 4-Space. Additionally, obtain characterization...
