Optimal circularly symmetric quantizers

Journal of the Franklin Institute, 1982
Abstract Polar coordinates quantization of the bivariate Gaussian and other cir- cularly symmetric sources has already been investigated. The schemes quantize the polar coordinates representation of the random variables independently in an attempt to reduce the mean square error below that of an analogous rectangular coordinates quantizer.

Symmetric Block Designs and Optimal Equidistant Codes

Problems of Information Transmission, 2020
In this paper, it is shown that any symmetric block design with parameters \((v, k, \lambda)\) generates optimal ternary and quaternary constant-weight equidistant codes, whose parameters are uniquely determined by the parameters of the block design.

Optimal trajectories for symmetric turns

American Journal of Physics, 2023
The problem of determining minimal time trajectories in a plane constrained by an upper bound on the magnitude of the acceleration vector is reexamined. In the previous work [Am. J. Phys. 49(7), 685–688 (1981)], a stationary solution of a functional, applied over curves in two-dimensional velocity space, was used to find explicit expressions for what ...

Optimization of symmetric tensor computations

2015 IEEE High Performance Extreme Computing Conference (HPEC), 2015
For applications that deal with large amounts of high dimensional multi-aspect data, it is natural to represent such data as tensors or multi-way arrays. Tensor computations, such as tensor decompositions, are increasingly being used to extract and explain properties of such data. An important class of tensors is the symmetric tensor, which shows up in

Optimal group symmetric localized molecular orbitals

Theoretica Chimica Acta, 1994
The concept and generating method of optimum group symmetric localized molecular orbitals (OSLMOs) are proposed. The OSLMOs have strong points of orthogonality, equivalence and symmetry, and they are simultaneously as close to the classical VB structure as possible.

Optimized symmetric discrete line arrays

IEEE Transactions on Antennas and Propagation, 1975
A generalization of Dolph's method for the synthesis of discrete antenna arrays is applied to six different symmetric line arrays. Based on these examples, it is concluded that 1) the field patterns of optimized symmetric line arrays with the same number of elements and with the same aperture are virtually indistinguishable and 2) optimized arrays with

The Most Likely Optimal Symmetric RVLC

IEEE Transactions on Communications, 2015
For each alphabet size up to 30, a symmetric reversible variable length code (RVLC) is determined which is most likely to be optimal in average codeword length. It is shown that these codes are optimal for more than half of all the possible sources.
