(2011-02-22)The United States contains an estimated 100,000 miles (160000 km) of levees in which erosion related issues are the top priorities. Proper documentation of overtopping induced erosion is a complicated issue involving the ...
-
(2017-07-28)Understanding the development of localization effects, such as shear and compaction bands, observed in sand specimens under compression, has been of research interest to understand elemental soil failure mechanisms. Various ...
-
(2009-05-15)A performance model and a reliability-based optimization model for flexible pavements that accounts for the effects of rehabilitation actions are developed. The developed performance model can be effectively implemented ...
-
(Stochastic Geomechanics Laboratory, 2021-03-24)Five research problems to identify evidence sources and provide initial validation of the risk framework model and data lake have been identified. We focused on COVID-19 Vaccination in the United States and Mexico as the ...
-
(Stochastic Geomechanics Laboratory, 2021-04-30)States in the U.S. have produced COVID-19 dashboards to communicate the status of the pandemic to the population. This research brief presents a summary of the available dashboards for the U.S. and Mexico states. Additionally ...
-
(Stochastic Geomechanics Laboratory, 2021-05-01)Covid-19 dashboards developed by state authorities in the U.S. present different variables to communicate the status and evolution of the pandemic in their territories. This research brief summarizes the different platforms ...
-
(Stochastic Geomechanics Laboratory, 2021-05-11)A literature review was conducted in order to identify the most impactful effects of natural hazards on the operation of supply chains. The review considered the body of research produced about this topic including the ...
-
(Stochastic Geomechanics Laboratory, 2021-05-11)This research brief includes a summary of various weather information services, detailing the procedures followed to obtain and generate data, and a breakdown of the information provided. Based on this information, the ...
-
(Stochastic Geomechanics Laboratory, 2021-05-28)Compare the total deaths per week during the 2020 pandemic against the expected deaths according to the reported in the previous four years.
-
(Stochastic Geomechanics Laboratory, 2021-05-28)Explore the association between the government's response to contain the pandemic and measurements of mobility reduction, economic activity, and unemployment.
-
(2010-10-12)In order to implement an accurate system that allows for absorption of reflected waves impinging to a wave maker (Active Reflection Absorption), it was required to apply a method to estimate properly the direction of arrival ...
-
(2015-12-16)The engineering design discipline of hydrology and hydraulics has, for the past several decades, been largely based on probabilistic design techniques involving recurrence interval storm and flood events. The engineering ...
-
(2012-10-19)Excavation activities like open cutting and tunneling work may cause ground movements. Many of these activities are performed in urban areas where many structures and facilities already exist. These activities are close ...
-
(2011-08-08)There has been increasing interest in evaluating the performance of existing reinforced concrete (RC) bridges just after natural disasters or man-made events especially when the defects are invisible, or in quantifying the ...
-
Adhesion in bitumen-aggregate systems and quantification of the effect of water on the adhesive bond (Texas A&M University, 2005-02-17)This research is intended to contribute toward the understanding, development, and implementation of a more fundamental design process for bituminous pavement materials, utilizing thermodynamic properties of the materials ...
-
(2014-08-11)This dissertation is aimed at advancing current understating and modeling of problems involving the complex soils systems. A wide range of problems are tackled here including those in: frozen soils; gas hydrate bearing ...
-
(2012-10-19)A new class of treatment processes called Advanced Reduction Processes (ARP) has been proposed. The ARPs combine activation methods and reducing agents to form highly reactive reducing radicals that degrade oxidized ...
-
(2018-08-28)In this dissertation, first, a flexible model is introduced using a mixture of the Negative Binomial (NB) distribution and a random distribution characterized by Dirichlet process (DP) (referred to as NB-DP). This modeling ...
-
(2012-12-05)Railroad bridges and culverts in the United States are often subject to extreme floods, which have been known to washout sections of track and ultimately lead to derailments. The potential for these events is particularly ...
-
(2011-02-22)Accurately and efficiently characterizing the material properties of hot mix asphalt (HMA) is critical to the design and development of pavements that can experience repeated loading for long periods of time and resist ...
