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). ...
Vertebral arteries
(Polytechnic University of Puerto Rico, 1998-06)
During the investigation period, which lasted almost four months, we made a research of the vertebral arteries in the posterior part of the head in children. During this time we investigated the size, diameter and the blood ...
Formulación de un modelo lagrangiano de partículas para simular la difusión de contaminantes atmosféricos. I
(Polytechnic University of Puerto Rico, 1998-06)
One of the most relevant aspects the atmosphere is its capacity for transporting substances, heat or momentum vertically among different levels. This property is of fundamental importance in the troposphere because otherwise ...
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 ...

(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 ...
