Application of the precursor transformation method to investigate cable tension influence in La Plata Bridge in Puerto Rico
(2015)
Bridge engineers are becoming more interested in structural health monitoring of cable stayed bridges in order to understand and mitigate problems such as from vibrations, fatigue, and corrosion. La Plata Bridge in Naranjito, ...
Fate and transport of TCE aqueous and non-aqueous phases in a karstified limestone physical groundwater model under different flow rates
(2019-12-06)
This research assesses the fate and transport of non-aqueous and dissolved trichloroethene (TCE) in a karstified limestone physical model (KLPM). The KLPM integrates a limestone block (15 cm x 15 cm x 77 cm) and simulates ...
Metodología para la evaluación de la consistencia de diseño de carreteras rurales de dos carriles
(2015)
The road geometric design consistency is correlated with its level of safety. This evaluation is performed in three stages: measure or estimation of the operational speed, calculation of the dependent variable in the ...
Utilización de synchro para mejorar el proceso de planificación de proyectos de construcción
(2015)
The construction project contract documents contain all information, specification, details, quantities and others information. Typically, these documents are prepared and delivered in different files that have to be ...
Fatigue life assessment of sandwich composite hulls under repeated slamming loads
(2014)
Slamming loads induced by waves on ships can cause severe damages on structural members which may compromise integrity and safety. Therefore, better understanding of the slamming problem is a topic of interest in marine ...
Factores de calidad de servicio para el sistema de carros públicos
(2010-12)
The “Carros Públicos” is a special demand response transit service operating in Puerto Rico. The sustained reduction in the system ridership could be related to its poor quality of service, as perceived by the population, ...
Stochastic simulation of tropical cyclones for quantification of uncertainty associated with storm recurrence and intensity
(2019-07-10)
Current practice for the design and assessment of coastal infrastructure requires the use of stochastic methods for the evaluation of the risk associated with coastal hazards such as storm surge and flooding induced by ...
Estudio de las órdenes de cambio en proyectos de diseño-construcción en las escuelas del siglo XXI
(2015)
Change orders have a strong potential to become difficult, because of its significant increase in cost and contract duration extension. This research identifies and evaluates the causes of change orders in design build ...
Modeling the land-use legacy effect of agricultural practices on the water quality of streams from forest watersheds of Puerto Rico
(2018-05)
In order to aid in the establishment of “reference” criteria the nutrient status and dynamics of
soils, water and stream sediments of a secondary forested watershed is being compared with the dynamics
of an “historically” ...
Water quality assessment with aquatic non-structural blocks made of coal ash aggregates mortars
(2012)
A handful of biochemical processes occur in aquatic environments. One of the problems that are mostly encountered in such environments is caused by excess nutrient input and subsequent algal bloom. A series of studies were ...
