Cálculo de los coeficientes de la ecuación de pérdidas para un sistema de generación de potencia
(Polytechnic University of Puerto Rico, 1995-06)
Calculation of the loss equation coefficients (Bmn) for a power generation system
Engineering has been very successful in the analysis of fuel costs, performance and efficiency of boilers, turbines, and generators. However, ...
Método analítico para determinar concesiones y análisis de rendimiento
(Polytechnic University of Puerto Rico, 1994-06)
We developed an analytical method to determine allowances and performance ratings based on human physiology. The theory about the human capacity to do work is analogous to the graph of steel fatigue used for structural ...
Variables that may predict the behavior of a student in his/her university life at Polytechnic University of Puerto Rico
(Polytechnic University of Puerto Rico, 1996-06)
The objective of this study is to establish the relationship, if any. between the Graduation Grade Point Average (GPA) of students that began as first year studentes at Polytechnic University of Puerto Rico and remained ...
Coeficientes de utilización de disyuntores ("breaker duty")
(Polytechnic University of Puerto Rico, 1993-06)
The breaker duty calculation is very important to the electric industry cause it shows which breakers overload under fault conditions. This way e utility determine the the extra capacity to add to those breakers or Aether ...
Wave solder process characterization by an experimental design approach
(Polytechnic University of Puerto Rico, 1992-06)
A manufacturing company in Puerto Rico was interested in evaluating the possibility of profiling all printed circuit board assemblies. Experimental design, a method for systematically planning engineering studies, offered ...
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.
Design and implementation of a virtual keyboard to aid handicapped people to use computers
(Polytechnic University of Puerto Rico, 1997-12)
This article describes our Capstone Design Project. The project requirements were to design and implement an interface software, to create a virtual keyboard on screen, optimized for typing Spanish language, controlled by ...
Low-volume speech
(Polytechnic University of Puerto Rico, 1998-06)
This project is the outcome of the necessity of a female patient of Parkinson's disorder and hearing disability of having someone to tell her to speak louder when her voice level could not be heard. The idea was to build ...
Strain gauge and micrometer instrumentation of a truss structure
(Polytechnic University of Puerto Rico, 1997-12)
This project was performed as part of the Structural Analysis courses in order to compare theoretical results of the response of simple structures with the experimental results obtained at the Structures Engineering ...
