Impact of coagulation on biofiltration : simultaneous removal of multiple trace organic compounds in biofilters
(2018-05-08)
Drinking water treatment plants are faced with a need to simultaneously remove natural organic matter (NOM), turbidity, and emerging trace organic compounds (TrOCs). Biofiltration is an attractive treatment option to remove ...
Wireless corrosion sensors for reinforced concrete structures
(2005-08-15)
Corrosion of embedded reinforcing steel and the resulting deterioration of concrete structures is a worldwide problem. As part of a health monitoring scheme for reinforced concrete structures, early detection of corrosion ...
Study of methods to assess the risk of damage for buried offshore power cables
(2022-12-05)
The motivation behind this study is to adapt the Carbon Trust’s Cable Burial Risk Assessment Methodology (CBRA) to the Outer Continental Shelf of the U.S. waters. The objectives of this study are: 1) develop data processing ...
Performance database interpolation and constrained nonlinear optimization applied to propulsor blade design
(2005-12-24)
Highest efficiency satisfying prescribed requirements has always been the objective of marine propeller design. As the loading of propeller is increased due to the growing demands of larger and faster ships, cavitation ...
Centrifuge measurement of two-phase transient flow in rigid porous media
(2016-08)
Gravity driven multi-phase flow in porous media is an important mode of fluid transport in several geologic settings. Some applications where gravity drainage may play an important role in the movement of a fluid can include ...
Impact of angularity, particle size and particle size distribution on the stiffness of the soil-geosynthetic composite
(2023-03-24)
Comparatively small strains are mobilized when the geosynthetic is used for its stiffening function, as is the case in the stabilization of road bases. The objective is to control the deformation in the soil-geosynthetic ...
Assessment of highway construction schedule review problems of Departments of Transportation : case study of Texas
(2022-11-17)
Schedule review is an important aspect of schedule management for the owners like the state Department of Transportation (DOTs) to successfully deliver projects on time. However, the quality of schedules submitted by the ...
Design of propulsors for underwater vehicle by comprehensive design method
(2022-12-02)
A comprehensive method which designs the propeller blades with the maximum efficiency to move a given underwater vehicle at a specified speed is introduced. A previously developed nonlinear optimization algorithm which ...
Blockchain-based methodology for confidential and traceable collaborative risk assessment
(2021-05-07)
Risk assessment is an important part of risk management in construction projects as it involves the identification, evaluation, and analysis of potential risk events, enabling project teams to properly mitigate them. To ...
An investigation of the effects of additive friction stir deposition on railroad rails
(2022-12-21)
This research investigated the effectiveness of additive friction stir deposition (AFSD) for strengthening existing railroad rails. AFSD is a solid-state additive manufacturing (AM) technology that is gaining popularity ...
