Theory of constraints will really improve your competitiveness
(Polytechnic University of Puerto Rico, 1993-06)
The Theory of Constraints (TOC) is a new management philosophy created by Eliyahu M. Goldratt to help an enterprise reach its goal. To accomplish this objective a company must change the paradigm of costs and follow two ...
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 generalized cross-product of vectors
(Polytechnic University of Puerto Rico, 1993-12)
The meaning of the scalar product of two vectors can be easily extended to a space of n dimensions. Similar generalization, related to the cross-product of vectors with more than three components, has not been formulated ...
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 ...
