The Uniform Association (UA) and Quasi-Uniform (QUA) models are used for analysis of two-way square contingency tables with ordered categories. When the QUA model does not fit data, one wants to measure degree departure from quasi-uniform association model. is calculated by usingthe power divergence statistics. In this study, as an alternative measures in literature, a estimate suggested. This ...

Three-dimensional filaments of quasi-geostrophic potential vorticity are generic features atmospheric and oceanic flows. They often generated during the strong interactions between three-dimensional vortices. contribute to a direct cascade enstrophy in spectral space. These correspond shear zones. Therefore they may be sensitive instabilities akin Kelvin–Helmholtz instability classical two-dime...

We consider the problem of recovering fusion frame sparse signals from incomplete measurements. These signals are composed of a small number of nonzero blocks taken from a family of subspaces. First, we show that, by using a-priori knowledge of a coherence parameter associated with the angles between the subspaces, one can uniformly recover fusion frame sparse signals with a significantly reduc...

If the symmetry condition in the definition of a pseudometric is deleted, the notion of a quasi-pseudometric is obtained. Asymmetric distance functions already occur in the work of Hausdorff in the beginning of the twentieth century when in his book on set-theory [27] he discusses what is now called the Hausdorff metric of a metric space. A family of pseudo-metrics on a set generates a uniformi...

The main objective of this project is to design the full-rate Space-Time-Frequency Trellis code (STFTC), which is based on Quasi-Orthogonal designs for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. The proposed Quasi-Orthogonal Space-Time-Frequency Trellis code combines set partitioning and the structure of quasi-orthogonal space-frequency desi...

A flow of electrically conducting fluid in the presence of a steady magnetic field has a tendency to become quasi two-dimensional, i.e. uniform in the direction of the magnetic field, except in thin so-called Hartmann boundary layers. The condition for this tendency is that of a strong magnetic field, corresponding to large values of the dimensionless Hartmann number (Ha >> 1). This is analogou...

Pseudo-random number sequences have been used in Monte Carlo methods in wide areas of science and engineer. Recently, quasi-random number sequences having uniform distribution property are used in numerical integrations, particle transport problems, financial problems and so on. Here, I survey on the quasi-random number generation and its applications. At the end, I discuss about the possible i...
