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 ...
Free energy in expansive clays : a practical exploration of the role of suction in clay swelling and temperature-dependent permittivity measurements
(2022-12-02)
Expansive clays are common throughout the world and are responsible for significant damage to pavements and other lightly loaded structures. While many of the fundamental properties of clay minerals are well-known, several ...
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 ...
Thermal desorption transformation mechanisms and pathways promoted by metal oxides and organic matter in contaminated soils
(2020-05-08)
Thermal desorption is a common soil remediation technology that can effectively treat soils contaminated with VOCs and SVOCs. However, due to the high remediation temperatures, contaminants can undergo transformation during ...
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 ...
Droplet interface bilayer (DIB) as a model for the study of water and ion transport in membrane proteins and pores
(2022-08-10)
Droplet interface bilayers (DIBs) are self-assembled lipid bilayers formed when connecting two water droplets enclosed by a lipid monolayer in a hydrophobic environment. Since the development of the technique in 2006, DIBs ...
