Design and implementation of a virtual keyboard to aid handicapped people to use computers
(Polytechnic University of Puerto Rico, 1997-12)
This article describes our Capstone Design Project. The project requirements were to design and implement an interface software, to create a virtual keyboard on screen, optimized for typing Spanish language, controlled by ...
Low-volume speech
(Polytechnic University of Puerto Rico, 1998-06)
This project is the outcome of the necessity of a female patient of Parkinson's disorder and hearing disability of having someone to tell her to speak louder when her voice level could not be heard. The idea was to build ...
Strain gauge and micrometer instrumentation of a truss structure
(Polytechnic University of Puerto Rico, 1997-12)
This project was performed as part of the Structural Analysis courses in order to compare theoretical results of the response of simple structures with the experimental results obtained at the Structures Engineering ...
Design and analysis of multi-section eccentric shaft
(Polytechnic University of Puerto Rico, 1996-12)
In this report the preliminary design and analysis of multi-section eccentric shaft to be used on four-rotor Wankel rotary engine is discussed. Only a static analysis was performed due to time constraints. This novel design ...
Determination of soil strength parameters from unconfined compression testing on partially saturated soils
(Polytechnic University of Puerto Rico, 1996-12)
The uneonfined compression test is used in most geotechnical studies to y -determine soil strength parameters. This test is recommended for fine cohesive > ^ soils with a degree of saturation of more than 90%. It has been ...
Inscribed r-gons: A Combinatorial approach
(Polytechnic University of Puerto Rico, 1996-12)
The author uses the concept of circular combinations to find the number of r-gons that can be inscribed in a n-gon.
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 ...
Implementation of the stiffness method within MathCad numeric computation environment
(Polytechnic University of Puerto Rico, 1996-12)
This article presents a case study of a simple planar framed structure to show an original implementation of the stiffness method of structural analysis within MathCad numeric computation environment. This approach was ...
