Matrix approach to the problem of matrix partitioning

Proceedings of 1995 IEEE International Symposium on Information Theory, 2002
We derive upper and lower bounds on the number of all variants a rectangular M/spl times/N matrix can be partitioned into fragments. Next the problem of matrix partitioning is considered as a particular example of a more general problem of constructing two-dimensional Markov processes (fields) on discrete rectangular lattices.

A matrix approach for FCSR automata

Cryptography and Communications, 2011
LFSRs are primitives widely used in information theory, coding theory and cryptography. However since 2002, they have faced algebraic attacks. To avoid this kind of attacks, FCSRs have been proposed as an alternative in [2-4]. In this paper, we first give a general representation of 2-adic automata using a traditional matrix representation.

A Contemporary Approach to Matrix Acidizing

SPE Production & Facilities, 1997
SummaryThis paper presents an updated look at the many variables associated with successful matrix acidizing. Damage types and formation characteristics significant when considering formation damage and damage removal are presented. Emphasis is placed on knowledge of formation mineralogy and temperature. The requirement for and the function of the many

The matrix approach

1998
It is not a coincidence that the finite element method blossomed at the time when computers were being developed, because it calls for a vast amount of computation for a problem of even modest size. It requires the assembly and solution of a large system of linear equations and, in addition, benefits from the computer’s ability to present data ...

Matrix approach to boolean calculus

IEEE Conference on Decision and Control and European Control Conference, 2011
Using semi-tensor product of matrices and the matrix expression of logic, formulas for calculating Boolean derivatives are obtained. Using this form, the solvability of Boolean algebraic equations and Boolean differential equations is considered. Its application to fault detection of combinational circuits is investigated.
