Conforte con acondicionamiento de aire
(Polytechnic University of Puerto Rico, 1991-06)
Recorrido por toda la superficie terrestre cubriendo los cuatro cabos de la tierra para observar las caracteristicas ambientales que dominan en regiones particulares.
On the thermodynamic consistency of the symmetric Poisson-Boltzmann equation in primitive model electrolytes
(Polytechnic University of Puerto Rico, 1991-06)
The study of electrolyte solutions poses several interesting features and
challenges. Their study is important, not only theoretically but for practical
reasons. Transport processes occur within the body as ionic ...

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 ...
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 ...
