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 ...
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 ...
Study of the density of states in amorphous Silicon-Hydrogen using the semiconductor/electrolyte system
(Polytechnic University of Puerto Rico, 1996-12)
Localized states in amorphous Silicon-Hydrogen are studied by pulsed measurements on the a-Si:H/electrolyte (S/E) system. The S/E interface is essentially blocking to current flow. As a result, surface space-charge layers, ...
Vector quantization
(Polytechnic University of Puerto Rico, 1996-12)
Data compression is the packing of data, the process of transforming a body data into a smaller representation from which the original or an approximation of the original can be computed at a later time. Most data sources ...
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 ...
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 ...
