Hadamard matrices, strongly regular graphs, and Galois fields
(Polytechnic University of Puerto Rico, 1994-06)
In this paper the author uses the concept of circulant matrices and the superposition principle to find, from the adjacency matrices of three regular graphs of order 8 and degree 2, tire adjacency matrix, M, of a strongly ...
Retículos cúbicos, ortomodulares, conexos, de altura 3 y configuraciones proyectivas ortomodulares conexas
(Polytechnic University of Puerto Rico, 1994-12)
Cubic orthomodular connected lattices of height 3 and orthomodular connected projective configurations
The construction of a connected orthomodular projective configuration, from a cubic, connected, orthomodular lattice ...
Análisis de corto circuito considerando cargas
(Polytechnic University of Puerto Rico, 1991-12)
Short circuit analysis is usually simplified neglecting shunt connections
including system loads. If under particular conditions, system loads cannot be
neglected, the superposition principle can be used, adding pre-fault ...

Filtros digitales para el procesamiento de imágenes
(Polytechnic University of Puerto Rico, 1992-12)
The purpose of this paper is to design filters capable of extracting the
contours of an image, thus reducing the distortion while processing an image.
In order to attain this goal, we developed a group of computer programs ...
