Gap acceptance studies and critical gap times for two-way stop controlled intersections in the Mayagüez Area
(2006)
Traffic analyses of priority intersections in Puerto Rico are currently performed using
parameters obtained from the Highway Capacity Manual (HCM). These values were
obtained from studies performed in other environments ...
On improving the performance of wood-zinc roof systems
(2006)
From hurricane Hugo to hurricane Georges, the majority of storm related losses in
Puerto Rico were attributed to wood-zinc houses and auxiliary structures. Efforts to

Earthquake induced damage estimation for steel buildings in Puerto Rico
(2006)
This work presents a method for estimating the expected damage caused by an earthquake on steel buildings in Puerto Rico. Since Puerto Rico is located between a series of tectonic faults, buildings could suffer the damages ...
Evaluación del uso de autoscope para conteos automáticos de vehículos en intersecciones
(2006)
This work presents a study that determines which non-intrusive equipment of automatic vehicle detection is better counting vehicles at intersections. After the literature review, the most promising was the technology that ...
Modelo de transporte de sedimento para flujo no permanente con las funciones de Yang y Ackers-White
(2006)
A mathematical model is presented for studying aggradation and degradation due to base level lowering in open channels. The Saint-Venant equations for unsteady flow and the sediment continuity equations for one-dimensional ...
Development of the regional intelligent transportation systems architecture for the San Juan Metropolitan Area
(2006)
Several regions around the United States and Puerto Rico have been facing increasingly
complex problems related to their transportation systems. In many cases, the use of advanced technology and strategies collectively ...

(2006-05)
El uso de los fustes barrenados como alternativa para la fundación profunda en puentes es cada vez más popular debido a que a veces esta tecnología resulta más atractiva sobre los pilotes hincados por sus ventajas económicas ...
Stress strain behavior and dynamic properties of Cabo Rojo calcareous sands
(2006-05)
This thesis involved studying the stress-strain behavior and dynamic properties of
uncemented calcareous sands from southwest Puerto Rico (Cabo Rojo sand). A silica
sand (South Bend sand) with similar grain sizes was ...
Qualitative identification of fecal coliform bacterial sources
(2006)
The main objective of this work is to provide a procedure to identify fecal coliform bacterial contamination sources within specific regions employing Geographical Information Systems (GIS) technology. The work presented ...
