PLAtestGA: A CNF-Satisfiability Problem for the Generation of Test Vectors for Missing Faults in VLSI Circuits
(Polytechnic University of Puerto Rico, 2000-06)
An evolutionary algorithm (EA) approach is used in the development of a test vector generation application for single and multiple fault detection of growth faults in Programmable Logic Arrays (PLA). Three basic steps are ...
ADSL: The Best Choice for Fast Internet Access
(Polytechnic University of Puerto Rico, 2000-12)
There is a real need for the increased bandwidth at a tower cost provided by ADSL (Asymmetric Digital Subscriber Line). The time is ripe for deployment due to the current competitive environment, and both A DSL transport ...
La enseñanza de la ingeniería en el siglo XXI
(Polytechnic University of Puerto Rico, 2000-06)
The teaching of the engineering disciplines during the XXI Century will continue, as has been established already, with a solid foundation in physical sciences, mathematics, liberal arts, engineering sciences and engineering ...
El redescubrirniento del yo y del otro: viajes, estructuras míticas, mitos y rituales de paso en Los pasos perdidos, de Alejo Carpentier
(Polytechnic University of Puerto Rico, 2005)
This paper is proposing the study of various themes related to Alejo Carpentier's Los pasos perdidos. Even though these themes have been studied before, it is proposing a new revision from a different perspective. First, ...
A Hybrid Deterministic/Genetic Test Generator to Improve Fault Effectiveness and Reduce CPU Time Run
(Polytechnic University of Puerto Rico, 2004)
This paper focuses on an evolutionary algorithm (EA) approach in the development of effective test vector generation for single and multiple fault detection in VLSI circuits. The genetic operators (selection, crossover, ...
Propagación de radiofrecuencias a través del espacio interestelar
(Polytechnic University of Puerto Rico, 2004)
Pulsar statrs act like simple radio stations consisting of a rotating two pole electromagnet. They behave like interstellar beacons radiating electromagnetic pulses in the microwave band.The interstellar radiation reaches ...
Antena inteligente con haces conmutados para redes de comunicaciones móviles*
(Polytechnic University of Puerto Rico, 2005)
The smart antenna technology for mobile communications has been the object of enormous worldwide interest during the last decade. The principal reason for the application of smart antennae is their potential for a large ...
Basic Plasma Diagnostics: Probes and Analyzers
(Polytechnic University of Puerto Rico, 2008)
What is plasma? Plasma is the fourth state of matter. Plasma are conductive assemblies of charged particles, neutrals and fields that exhibit collective effects. Plasma is profoundly influenced by the electrical interaction ...
Mass Spectrometric Study of Various Coated Targets Utilizing PUPR-MC Plasma Machine for NASA Solar Probe Space Mission
(Polytechnic University of Puerto Rico, 2008)
The NASA Solar Probe Space Mission will be a historic operation, flying for the first time into one of the last unexplored regions of the solar system, the Sun's atmosphere or corona; hopefully revolutionizing our knowlege ...
Design of an Automation and Control System for PUPR-MC Plasma Machine
(Polytechnic University of Puerto Rico, 2008)
The automation of Polytechnic University of Puerto Rico Mirror-Cusp (PUPR-MC) plasma machine is part of the work performed by the Plasma Engineering Laboratory in the experiments of the NASA Solar Probe Mission Thermal ...
