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 ...
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 ...
Modelaje matemático y simulación computadorizada del enfriamiento natural de una vivienda en Puerto Rico
(Polytechnic University of Puerto Rico, 1994-06)
The planning of social interest housing developed by the government of Puerto Rico during the sixties basically optimizes the economic aspects. Although, unfortunately, they shun a very important aspect in the intrinsic ...
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 ...
Simulación de estaciones de trabajo ergonómicamente diseñadas para inspeccionar lentes de contacto
(Polytechnic University of Puerto Rico, 1994-06)
In this project we describe the ergonomic design of workstations for the inspection of contact lenses. MANNEQUIN, a simulation program, was used for the evaluation and proper design. The main objective of 111s project is ...

(Polytechnic University of Puerto Rico, 1994-12)
Analysis of the electrical protection system of IPR Pharmaceuticals
This study is based on the electrical distribution system of a pharmaceutical plant. The purpose of the study is to investigate why the low voltage ...
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 ...
Diseño y desarrollo de un controlador de temperatura para un horno de pruebas
(Polytechnic University of Puerto Rico, 1994-12)
Design and development of a temperature controller for a test oven
As a part of quality control process, the electronics industry must make different tests to electronic components. One of these tests allows us to determine ...
Control por "feedback" y "feedforward" aplicado a un proceso de múltiples entradas
(Polytechnic University of Puerto Rico, 1994-12)
Feedback and feedforward control applied to a multivariable process
In this paper we analyze three control systems for a multivariable chemical process. We also present the design of a feedback control system, a feedforward ...
