Explicit Orthonormal Bases For Functions Exhibiting The Rotational Symmetries Of A Platonic Solid, Yibin Zheng, Peter C. Doerschuk Oct 1994

Explicit Orthonormal Bases For Functions Exhibiting The Rotational Symmetries Of A Platonic Solid, Yibin Zheng, Peter C. Doerschuk

Department of Electrical and Computer Engineering Technical Reports

We compute explicit orthonormal bases for functions invariant under the rotational symmetries of a Platonic solid. Each function in the basis is a linear combination of spherical harmonics. For each symmetry (icosahedral, octahedral, tetrahedral) the calculation has three steps: First derive a bilinear equation for the coefficients by comparing the expansion of a symmetrized delta functioii in both spherical harmonics and the symmetric harmonics. The equation is parameterized by the location (Θ0,Ø0) of the delta function and must be ~at~isfiefodr all locations. Second, express t,he dependence on the delta function location in a Fourier (Ø0) and Taylor (Θ0) series and …


Dist A Distribution Independent Parallel Programs For Matrix Multiplication, Hyuk J. Lee, José A.B. Fortes Oct 1994

Dist A Distribution Independent Parallel Programs For Matrix Multiplication, Hyuk J. Lee, José A.B. Fortes

Department of Electrical and Computer Engineering Technical Reports

This report considers the problem of writing data distribution independent (DDI) programs in order to eliminate or reduce initial data redistribution overheads for distributed memory parallel computers. The functionality and execution time of DDI programs are independent of initial data distributions. First, modular mappings, which can be used to derive many equally optimal ant1 functionally equivalent programs, are briefly reviewed. Relations between modular mappings and input data distributions are then established. These relations are the basis of a systematic approach to the derivation of DDI programs which is illustrated for matrix-matrix multiplication(c = a x b). Conditions on data distributions …

Tree Structured Grobner Basis Computation On Parallel Machines, Hemal V. Shah, Jose A. B. Fortes Oct 1994

Tree Structured Grobner Basis Computation On Parallel Machines, Hemal V. Shah, Jose A. B. Fortes

Department of Electrical and Computer Engineering Technical Reports

With the advent of symbolic mathematical software packages such as Maple, Mathematics, and Macsyma, symbolic computation has become widely used in many scientific applications. Though a significant effort has been put in performing numeric computation on multiprocessors, symbolic computation on parallel machines is still in an unexplored state. However, symbolic mathematical applications are ideal candidates for parallel processing, because they are computationally intensive. This paper considers the parallel computation of Grobner basis, a special basis for a multivariate polynomial ideal over a field that plays a key role in symbolic computation. Large Grobner basis computation poses a challenging problem due …

C++ Class Libraries For Error Control Codes, Jamshid Nazari, Okan K. Ersoy Aug 1994

C++ Class Libraries For Error Control Codes, Jamshid Nazari, Okan K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

A tutorial on error control code is given and encoding and decoding using finite field transforms are outlined. Several C++ class libraries are then designed to implement some of the concepts in error control codes. A high level description of these libraries are given and several programs that. uses these libraries are presented. RS and BCH codes can be generated by these libraries from primitive polynomials where the user specifies the code size and number of errors to be corrected. Using these libraries power progra.ins in error control codes can be writtnen in less than few pages.
