Use of genetic algorithms in experimental design optimization and thermal property estimation
(Polytechnic University of Puerto Rico, 1997-06)
The goal of this paper is both to introduce the fields of experimental design optimization and thermal property estimation and to present Genetic Algorithm (GA) optimization method to the faculty of PUPR. This research ...
Classification of nr-graphs
(Polytechnic University of Puerto Rico, 1997-06)
When all possible r-gons are inscribed in an n-gon, the resulting n-graph falls into one of the following three categories: s-regular (sr or strongly regular), //-regular, or regular (k-regular). The definitions and necessary ...
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 ...
Colapso de un muro de contención construido con mampostería
(Polytechnic University of Puerto Rico, 1997-06)
This study presents the analysis of a masonry retaining wall, typically built in Puerto Rico to stabilize and retain slopes. How safe and well built are these walls?. Have they the adequate resistance to efficiently retain ...
Disposición adecuada de desperdicios
(Polytechnic University of Puerto Rico, 1997-06)
En abril la Autoridad de Desperdicios Solidos celebro el mes de reciclaje y manejo adecuado de los residuos solidos. En mayo se celebro en Puerto Rico la semana del ingeniero y el agrimensor. Posiblemente se estaran ...
Architects and engineers: What makes the difference?
(Polytechnic University of Puerto Rico, 1997-12)
The historic dispute between architects and engineers, particularly civil engineers, is nonsense. Both professions are prestigious and dedicate themselves to covering separate and distinct aspects of the design of buildings ...
Dynamic analysis of rigid pavements and bridges under moving vibrating trucks
(Polytechnic University of Puerto Rico, 1997-12)
The computer program UPR-PAVI2 was developed to perform the dynamic analysis of a pavement slab or a bridge superstructure loaded with moving vibrating trucks. UPR-PAVI2 can model the soil, slab and truck, considering their ...
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 ...
Experiencia con el proceso de mejoramiento de la calidad en una empresa manufacturera
(Polytechnic University of Puerto Rico, 1997-06)
The successful implementation of a continuous quality improvement process in a manufacturing enterprise requires that certain
vital conditions are present. It is also essential that those conditions be fully developed ...
