RISUse of the Lorenz Curve to Quantify Statistical Nonuniformity of Sediment Transport Rate
Publisher: American Society of Civil Engineers
Abstract: The Lorenz curve and the Gini index are statistical tools that have been widely used to quantify nonuniformity in economics, ecology, and medicine, but have apparently not been previously applied in hydraulic engineering. ...
Discussion of “Protecting Vertical-Wall Abutments with Riprap Mattresses” by A. H. Cardoso and C. M. S. Fael
Publisher: American Society of Civil Engineers
Tribological Performance of Soft Magnetic Composite Materials for Gas Turbine Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Soft magnetic composites (SMCs) have gained attention in the last years of their usage in more compact and powerful electromechanical systems. These materials are used to combine the application of metallic material to the ...
Identification of Motor Control Objectives in Human Locomotion via Multi-Objective Inverse Optimal Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Predictive simulations of human motion are a precious resource for a deeper understanding of the motor control policies encoded by the central nervous system. They also have profound implications for the design and control ...
Live-Bed Pier Scour in a Covered Flow
Publisher: American Society of Civil Engineers
Abstract: Results are presented for a novel experimental investigation of live-bed scour at a cylindrical pier in covered flow. The experimental campaign also comprehended a reference scour test in clear-water conditions. Results ...
Symmetry Properties in the Symmetry-Breaking of Nonsmooth Dynamical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the block simply supported on a harmonically moving ground is assumed as a system well representing a typical nonsmooth dynamical behavior. The aim of the work is to carry out ...
Roughening Elements as Abutment Scour Countermeasures
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of clear-water scour experiments with a vertical-wall abutment. The upstream face of the latter was provided with roughening elements as devices to intercept the downflow responsible for the ...
Revisiting Generation and Meshing Properties of Beveloid Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The teeth of ordinary spur and helical gears are generated by a (virtual) rack provided with planar generating surfaces. The resulting tooth surface shapes are a circle-involute cylinder in the case of spur gears, and a ...
Celerity and Height of Aggradation Fronts in Gravel-Bed Laboratory Channel
Publisher: ASCE
Abstract: We present the results of laboratory experiments specifically designed to quantify the height and migration rate of an aggrading gravel front. The experiments were performed in sediment feed mode with constant water and ...
Role of Stress History on the Swelling–Shrinkage Behavior of Compacted Scaly Clay
Publisher: ASCE
Abstract: Compacted scaly clays are complex geomaterials widely used for the realization of dam cores and waste dump liners. This research aims to investigate the swelling/shrinkage behavior of these geomaterials subjected in an ...
