EVALUATION OF RECYCLED PLASTIC PINS AS SHEAR KEYS IN MSE WALL BASE
(2021-05-06)
Mechanically Stabilized Earth (MSE) walls have been widely used as retaining structures due to their flexible nature, a better tolerance against differential settlement, and many other factors. However, external stability ...
USE OF TIME-DOMAIN REFLECTOMETRY TO CHARACTERIZE THERMAL AND HYDRAULIC PROPERTIES OF UNSATURATED SANDS
(2021-01-06)
Unsaturated soil is an essential consideration for many geotechnical engineering fields, for example, soil bearing capacity, soil lateral earth pressure, slope stability analysis, and seepage-related problems. Thermal-hy ...
Development of a Model to Prioritize Inspection and Condition Assessment of Gravity Sanitary Sewer Systems
(2021-08-26)
Underground utilities and wastewater collection systems deteriorate over time demanding utility owners to involve in continuous revisions and development of their asset management frameworks to maintain the functionality ...
PERFORMANCE OF CRACKED REINFORCED CONCRETE PIPES SUBJECTED TO DIFFERENT ENVIRONMENTAL CONDITIONS
(2020-09-01)
Performance of reinforced concrete pipes, as a major part of the water and waste-water infrastructure, plays an important role in the resilience and sustainability of today’s modern cities. Cracks may appear in these pipes ...
STATISTICAL MODELS OF PIPE SERVICE LIFE TOWARDS ARTIFICIAL INTELLIGENCE BASED DECISION SUPPORT
(2020-08-18)
In this dissertation, through utilizing various artificial intelligence-based as well as statistical models, an effort has been made to investigate the deterioration of sewer pipes. Once the deterioration rates of sewer ...
DEVELOPMENT OF REDUCTIVE/OXIDATIVE TREATMENT STRATEGY FOR THE REMOVAL OF PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) IN WATER
(2020-08-10)
The detrimental health effects of halogenated compounds in humans has been well documented, and the frequent occurrence of per- and polyfluoroalkyl substances (PFAS) in the water environment is a recent global concern. ...
DEVELOPMENT OF A STRUCTURAL DESIGN METHODOLOGY FOR POLYMERIC SPRAY APPLIED PIPE LININGS
(2020-09-04)
Buried culverts are important components of the highway infrastructure. Most large culverts are built decades ago from corrugated metal or reinforced concrete materials and now have reached their design lives. Trenchless ...
IMPROVING OPERATIONAL HYDROLOGIC FORECASTING VIA CONDITIONAL BIAS-PENALIZED MULTI-SENSOR PRECIPITATION ESTIMATION AND MULTI-MODEL STREAMFLOW PREDICTION
(2021-05-09)
Many multivariate analysis techniques involve minimizing mean square error (MSE) or error variance under unbiasedness. In the presence of observation error, variance minimization tends to introduce negative and positive ...
Active Transportation and Health: Understanding the Impact of Transportation-Related Physical Activity on Health
(2020-08-21)
Car-oriented infrastructure in the U.S. leads to physically inactive lifestyles and negative health outcomes. To promote physical activity, public health officials encourage active transportation, namely biking and walking ...
UTILIZING LOAD TESTS AND SITE INVESTIGATION DATA TO PREDICT DESIGN LOAD CAPACITIES FOR DRILLED SHAFTS IN DIFFERENT GEOLOGIC FORMATIONS
(2021-08-06)
Precise predictions of the design capacities of drilled shafts on weak rock formations is vital for a better design of foundations. Irregularities in rock formations due to weathering cause discrepancies in actual bearing ...
