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 ...
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 ...
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.
Architects and engineers: What makes the difference?
(Polytechnic University of Puerto Rico, 1997-12)
The historic dispute between architects and engineers, particularly civil engineers, is nonsense. Both professions are prestigious and dedicate themselves to covering separate and distinct aspects of the design of buildings ...
Dynamic analysis of rigid pavements and bridges under moving vibrating trucks
(Polytechnic University of Puerto Rico, 1997-12)
The computer program UPR-PAVI2 was developed to perform the dynamic analysis of a pavement slab or a bridge superstructure loaded with moving vibrating trucks. UPR-PAVI2 can model the soil, slab and truck, considering their ...
Determination of interface roughness and its correlation in amorphous-silicon/ amorphous-germanium multilayers
(Polytechnic University of Puerto Rico, 1996-06)
The importance of surfaces and interfaces of materials is increasing in many technological areas. In the microelectronic industry, for example, the J current trend is toward even faster and smaller electronic devices. ...
