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 ...
The Implementation of New Technology: Ethical Principles and Ethical Reasoning Elements
(Polytechnic University of Puerto Rico, 1999-06)
We explored valuable ethical issues on the New Technology Implementation (NTI). A successful approach to assess and manage health-related issues associated with the installation of new technology (specially those related ...
Development of an Interactive Finite Element Analysis Program Within MS Windows 95 Environment
(Polytechnic University of Puerto Rico, 1999-06)
The objective of this project was to develop a highly interactive, graphically oriented, special purpose Finite Element Analysis program, that utilizes the MS-Windows 95 environment as the Graphical User Interface (GUI). ...
Fingerprints Recognition Using a Neural Network
(Polytechnic University of Puerto Rico, 1999-06)
A fingerprint recognition approach, based on a backpropagation algorithm using a neural network, is presented. The purpose of our work is to show the relevance of the fingerprint method characterization by using the ...
PUPR Looks Forward to the 21st Century with a Program of Research and Development
(Polytechnic University of Puerto Rico, 1999-06)
The New Economic Development model adopted by the Government of Puerto Rico is an effort to provide a diversified and solid foundation for future economic development in view of changes in the global economic context. The ...
New Tools for the Design and Analysis of Complex Springs
(Polytechnic University of Puerto Rico, 1999-06)
The molded case circuit breaker industry, in general, produces great families of breakers, i.e., the bolt-on and the plug-in units. The bolt-on unit uses a screw to connect the unit to the bus bar of the panelboard. In the ...
El impacto del paradigma constructivista en la enseñanza de matemáticas
(Universidad Politécnica de Puerto Rico, 1999-12)
The constructivist paradigm offers important
implications to educators about the teaching and
learning of mathematics. The curricular reforms in the mathematics classroom, in its majority, emerge from constructivist ...
Tools for Predicting Uncertainty and confidence Intervals in Radiometric Data Products
(Universidad Politécnica de Puerto Rico, 1999-12)
Spaced-based observations of atmospheric
energetics, such as those provided by NASA’s
Clouds and the Earth’s Radiant Energy System
(CERES), produce data products intended to be
shared with the larger scientific community ...
Simulation of the Antenna Pattern of Arbitrarily Oriented Very Large Phase/Time-Delay Scanned Antenna Arrays with Systematic and Random Errors
(Universidad Politécnica de Puerto Rico, 1999-12)
A computer simulation to determine the field
pattern of arbitrarily oriented, very large phase/time delay scanned antennas was developed. The simulation takes into account errors present in antenna arrays. These are ...
Semisolid Metal Processing
(Universidad Politécnica de Puerto Rico, 1999-12)
Processing of metal alloys in their mushy state
represent a new trend in metal processing. The process produces components with low porosity,
high crack resistance, fine microstructure, and
better mechanical properties ...
