Identifying damage in reciprocating air compressors
(Polytechnic University of Puerto Rico, 1994-12)
We used a parametric analysis for a reciprocating air compressor to determine its working conditions. We also connected measuring devises which allowed us to determine the real performance of our compressor. From this point ...
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 ...
Banco de pruebas de relés
(Polytechnic University of Puerto Rico, 1993-12)
Description of a test bench that simulates the operation of the protection system of a transmission center. The test bench developed integrates several electromagnetic devices, known as relays, that work together to protect ...
Theory of operation of today CD systems
(Polytechnic University of Puerto Rico, 1993-12)
In this article we examine the main events that lead to the invention of the compact disc or CD, as we all call it. We consider the most important components of the playback section of the CD such as the pick-up circuit, ...
Diseño de un microprocesador
(Polytechnic University of Puerto Rico, 1994-06)
We show the design of a microprocessor that includes the set of instructions, the addressing modes and the cycle of fetch-decode-execute an instruction. We chose the registers used in the design from the board and then ...
Diseño de un sistema de producción de discos para pararrayos mediante la simulación computadorizada del proceso
(Polytechnic University of Puerto Rico, 1993-06)
This project is based upon proposed changes to the design of facilities and the acquisition of new equipment for a company. Our goal is to optimize the use of the equipment and the human and economic resources using the ...
Diseño de experimentos con una máquina de revestimiento de tabletas en una industria farmacéutica
(Polytechnic University of Puerto Rico, 1994-06)
A subtle but meaningful kind of loss is the acceptance of subjective beliefs within an organization. Profits are never a result of mysticism. Subjectivity without a precise base is a way of lying and, although it might not ...
A utility for Netware: REMOTE
(Polytechnic University of Puerto Rico, 1994-06)
We used the C language code to develop a utility that allows two or more workstations connected to the same physical network running the network operating system Netware to communicate and perform remote operations. The ...
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 ...
Pérdidas de agua en los sistemas fluviales
(Polytechnic University of Puerto Rico, 1993-12)
In this paper we identify those elements that contribute to the undetermined water losses in the Puerto Rico Water and Sewers Authority. We also provide detailed recommendations to reduce these losses.
