Crash modification factors for rumble strips treatment in freeway
(2015-12)
Longitudinal shoulder rumble strips is a safety feature or treatment on a paved shoulder, capable of alerting drivers that their motor vehicle is departing the traveled lane. This treatment has proven to be effective ...
Temporal outlier detection using dynamic Bayesian networks and probabilistic association rules
(2019-12-10)
Temporal datasets provide records of the evolution and dependencies of random variables over time. Recently, there has been an increase in the application of temporal datasets in areas such as intrusion detection, fraud ...
The diet of masked, brown and red-footed boobies (sulidae: pelecaniformes) in the mona passage, Puerto Rico
(2009)
From four visits to Monito Islet in the Isla de Mona Natural Reserve, the prey
description (diversity, dominance, importance, length, taxonomy and volume), the dietary
niche (breadth, contribution and overlap) and the ...
Institucionalidad colonial y formación del canon : el vacío de la literatura puertorriqueña en la educación pública
(2019-05)
Esta investigación es un estudio de la asignación de textos literarios que presentó el Departamento de Educación de Puerto Rico en el Programa de lengua y literatura españolas para la escuela superior en 1937. Demuestra ...
Distension mechanism of a compliant tube caused by partial downstream fluid flow obstruction
(2019-12-10)
This investigation examines the distension of a silicone tube through experiments and finite element modeling. Three experiments were conducted to examine the distension of the tube. Two experimental configurations were ...
Photovoltaic inverter voltage regulation performance evaluation using a power hardware-in-the-loop setup on distribution system feeders
(2019-12-10)
Real-Time (RT) simulation introduces fast computational capabilities with high-fidelity mathematical models to study large or complex operational systems in the aerospace, automotive, energy, or other domains. The advantage ...
Methemoglobin I from lucina pectinata: A feasible alternative for a prototype biosensor for hydrogen sulfide
(2018)
Hydrogen sulfide (H2S) is one spiteful smelling gas that was considered for
centuries extremely noxious to biological species. However, the fact that three
enzymes endogenously catalyze H2S synthesis and that it has been ...
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 ...
Rheology of rodlike nanoparticle suspensions in lyotropic liquid crystalline polymers
(2013)
Liquid crystalline polymers are ideal to develop oriented and anisotropic materials. The incorporation of a nanoparticle may improve or add properties to a matrix. Small concentrations of particles smaller than the liquid ...
Synthesis and characterization of flexible pillared-layer structured porous coordination polymers and determination of gas adsorption-desorption properties
(2018-05)
Porous coordination pillared-layer structured polymers are a particular category of 3D uniform crystal materials constituted by well-defined two-dimensional layers (specially formed by a combination of metal ion or metal ...
