Biodeterioration of PVC plastics, biochemical fate of DEHP, and bioreactor landfills for DEHP-containing leachate management
(2014-12)
Di-(2-ethylhexyl) phthalate (DEHP), a widely used plasticizer in the manufacture of polymeric materials such as polyvinyl chloride, was studied in order to understand its fate and transport in complex environments such as ...
Red light running and driver behavior at signalized intersections in western Puerto Rico
(2011)
Red Light Running (RLR) is a potentially severe safety issue at signalized intersections. To determine the driver reaction at the end of the green period at signalized intersections, a RLR study was performed using 32 ...
Long term behavior of hygrothermaly conditioned concrete-filled fiber-reinforced polymetric tubes subjected to axial loads
(2011)
This study evaluated the behavior of concrete filled FRP tubes (CFFT) subjected to moisture absorption condition. Accelerated aging by means of hygrothermal process was conducted to predict long-term mechanical behavior ...
Performance of landfills with coal combustion byproducts aggregates as an alternative reactive daily cover
(2012-05)
A landfill is an engineered facility for the disposal of wastes. It is designed and operated to minimize public health and environmental impacts. However, land availability is the limiting factor for the operation and ...
Shear strength and displacement capacity of squat reinforced concrete shear walls
(2016)
Squat reinforced concrete (RC) walls are essential structural components in nuclear power facilities (NPP) and in many civil structures. An adequate prediction of the shear strength and displacement capacity of these ...
Study of light weight, high strength, multifunctional composite material: Aluminum reinforced with AIB2 particles
(2017)
Aluminum, its alloys and composites are widely used in many modern life applications, such as microelectromechanical systems. In this research, an aluminum matrix composite reinforced with AlB2 particles was studied in ...
Rehabilitation of RC residential houses on gravity columns over slope terrain
(2015)
It is well known that Puerto Rico is exposed to the risk of experiencing strong earthquakes, since it is located in an earthquake prone region. It is a fact that in Puerto Rico there are many houses that are built over ...
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 ...
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 ...
A computational framework for structural health monitoring of reinforced concrete structures
(2015)
This research work is aimed to develop a robust Structural Health Monitoring (SHM) scheme that combines modern system identification methodologies and advanced signal processing techniques to improve the capabilities of ...
