Permutation source codes are a class of structured vector quantizers with a computationally-simple encoding procedure. In this thesis, we provide two extensions that preserve the computational simplicity but yield improved operational rate–distortion performance. In the first approach, the new class of vector quantizers has a codebook comprising several permutation codes as subcodes. Methods fo...

We investigate the interactions of two distinct loss recovery mechanisms employed by TCP and IS-707, a partial error recovery Radio Link Protocol (RLP), during a long-time, low-speed TCP connection over a radio channel with correlated losses. In such a scenario not only the unrecovered frame losses, but also the slow RLP frame loss recovery mechanism trigger the TCP congestion avoidance, result...

In IEEE 802.11 Wireless LAN (WLAN) systems, techniques such as acknowledgement, retransmission and transmission rate adaptation are frame-level mechanisms designed for combating transmission errors. Recently practical sub-frame level schemes, such as frame combining and partial packet recovery, have been proposed by the research community. In this paper, we present experimental results obtained...

The acquisition of geometric information from realworld objects has become a major way of modeling complex scenes and environments. Unfortunately, most optical methods for geometric model acquisition require the combination of partial information from different view points in order to obtain a single, coherent model. This, in turn, requires the registration of partial models into a common coord...

In this paper, we will provide a simple method for starting with a given finite frame for an $n$-dimensional Hilbert space $mathcal{H}_n$ with nonzero elements and producing a frame which is $epsilon$-nearly Parseval and $epsilon$-nearly unit norm. Also, the concept of the $epsilon$-nearly equal frame operators for two given frames is presented. Moreover, we characterize all bounded invertible ...

Abstract This paper concerns the notions of closed and open maps in setting partial frames, which, contrast to full do not necessarily have all joins. Examples these include bounded distributive lattices, $$\sigma $$ σ - $$\kappa κ -frames frames. We define using geometrically intuitively app...

We determine two-particle scattering phase shifts and mixing angles for quantum theories defined with lattice regularization. The method is suitable for any nonrelativistic effective theory of point particles on the lattice. In the center-of-mass frame of the two-particle system we impose a hard spherical wall at some fixed large radius. For channels without partial-wave mixing the partial-wave...

in this paper, we show that in each nite dimensional hilbert space, a frame of subspaces is an ultra bessel sequence of subspaces. we also show that every frame of subspaces in a nite dimensional hilbert space has frameness bound.
