Computation of gradually varied flow in channel networks with hydraulic structures
(2018-01-12)
Irrigation canals transport water from a source, such as a natural river or a reservoir, to a crop
field or a community, making them vital for agriculture. This research develops a computer
model to determine the water ...
Diseño de redes estructuradas de transportación colectiva incorporando en forma explícita los beneficios al usuario
(2018-12-12)
Public transportation is considered one of the main structural elements of urban transportation due to the decided advantages it offers over other means of transportation considering the amount of public space it takes up. ...
Strong motion duration influence on nonlinear seismic response.
(2018-12-11)
The preferred representation of seismic hazard in structural design and assessment continues to be based on the elastic response spectrum. Even when dynamic time history analyses are required, the acceleration time histories ...
Operation and safety evaluation of roadway geometrics and posted speed limit in the PR-22 dynamic toll lane using a driving simulator
(2018)
This research presents the initial in-depth study of the PR-22 Dynamic Toll Lane (DTL) using the University of Puerto Rico at Mayagüez (UPRM) driving simulator, the first of its kind in Puerto Rico. The PR-22 DTL is a ...

(2018)
The town of Rincón is in the northwest corner of Puerto Rico with a population of about 15,000. Like other US American beach community, Rincón’s local economy prosperity thrives on the condition of its beaches and has been ...
User performance analysis of a two-way left turn lane using a driving simulator
(2018-12)
This research’s aim is to study the behavior of drivers when the cross-section of the roadway is modified to include a Two-Way Left Turn Lane (TWLTL). This research study used the UPRM driving simulator to collect driver ...
Characterization of an optimized hig performance concrete with partial replacement of cement by fly ash and nanosilica
(2018)
Modern construction industry requires new technologies to comply with increasingly stricter environmental regulations. In particular, cutting back cement demand in concrete fabrication lowers carbon dioxide emissions caused ...
Relationship assessment between contamination of groundwater ant tap water in Karst systems
(2018)
Karst groundwater systems are a significant source of drinking water, but also are highly vulnerable to contamination.Contamination may reach tap water and pose potential threat to
public health. This study aims at ...
