Bridges under dynamic loads: comparison between finite element analysis and experimental results
(Polytechnic University of Puerto Rico, 1997-06)
AASHO Road Test performed experimental tests on bridges under dynamic and static truck loads. This paper shows a comparison between AASHO's tests and the analytical results of UPR-PAVI2, a computer program developed by the ...
Implementation of the stiffness method within MathCad numeric computation environment
(Polytechnic University of Puerto Rico, 1996-12)
This article presents a case study of a simple planar framed structure to show an original implementation of the stiffness method of structural analysis within MathCad numeric computation environment. This approach was ...
Golden section search solution of single variable optimization problems using MathCad
(Polytechnic University of Puerto Rico, 1997-06)
The method of solution presented in this article is based on a searching technique known as the Golden Section Rule. This method can be used for solving single-variable optimization problems without constraints, but for ...
Colapso de un muro de contención construido con mampostería
(Polytechnic University of Puerto Rico, 1997-06)
This study presents the analysis of a masonry retaining wall, typically built in Puerto Rico to stabilize and retain slopes. How safe and well built are these walls?. Have they the adequate resistance to efficiently retain ...
Disposición adecuada de desperdicios
(Polytechnic University of Puerto Rico, 1997-06)
En abril la Autoridad de Desperdicios Solidos celebro el mes de reciclaje y manejo adecuado de los residuos solidos. En mayo se celebro en Puerto Rico la semana del ingeniero y el agrimensor. Posiblemente se estaran ...
PLAGA: A Highly Parallelizable Genetic Algorithm for Programmable Logic Arrays Test Pattern Generation
(Polytechnic University of Puerto Rico, 1999-06)
An evolutionary algorithm (EA) approach is used in the development of a test vector generation application for single and multiple fault detection of shrinkage faults in Programmable Logic Arrays (PLA). Three basic steps ...
Reduction of downtime through the design of TPM and the implementation of some techniques of SMED system at high speed packaging lines
(Polytechnic University of Puerto Rico, 1996-06)
This project was developed at a pharmaceutical facility located in the eastern area of Puerto Rico. The company manufactures oral contraceptives and analgesics. In the analgesic branch a new product is being introduced, ...
Fallas de alta impedancia en los sistemas de distribución eléctrica
(Polytechnic University of Puerto Rico, 1992-06)
Most of the time, a fault in an electrical power system presents a much higher current than the current that flows in the system during. normal conditions. This fault current is harmful for the components of the system ...
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 ...
