RISDexterity and Adaptive Control of Planar Parallel Manipulators With and Without Redundant Actuation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to determine whether a planar parallel manipulator with redundant actuation has better tracking accuracy than a planar parallel manipulator without redundant actuation. The effects of the ...
Optimization of Operation Strategies for an Interbasin Water Diversion System Using an Aggregation Model and Improved NSGA-II Algorithm
Publisher: ASCE
Abstract: To maximize the benefits of an interbasin water diversion system (IBWD), an aggregation model and improved NSGA-II algorithm were constructed to establish operation strategies for water diversion and water supply. An ...
Response Efficacy Perception and Taking Action to Prepare for Disasters with Different Lead Time
Publisher: ASCE
Abstract: This study investigated how disaster types, namely those with shorter and longer warning lead times, contextualized individuals’ preparatory actions, especially those associated with their response efficacy perception ...
Strain Distribution of Dowel-Type Connections Reinforced with Self-Tapping Screws
Publisher: ASCE
Abstract: Current limited guidance on the selection of screws together with undefined design specifications restricts the effectiveness of self-tapping screws as reinforcement on timber members to control crack propagation. Using ...
Point-Based Mesoscopic Modeling and Simulation for Two-Step 3D Braided Composites
Publisher: ASCE
Abstract: A point-based modeling scheme for the mesostructure of a two-step three-dimensional (3D) braided composite is proposed. The yarn path and the section profile are more realistic than the traditional mesh-based model, and ...
Design and Optimization of Dimethyl Ether Steam-Reforming Reactor
Publisher: ASCE
Abstract: In this paper, a numerical model of the dimethyl ether (DME) steam reformer was developed. The established numerical model was solved using commercially available software. An experimental platform was set up to validate ...
Visualization Investigation of the Plugging Effect on Open-Ended Pipe Pile Jacked in Transparent Sand
Publisher: ASCE
Abstract: This paper describes the findings of a study of the soil plugging progressive formation process during pipe pile penetration using a transparent soil model test. The objective of this study is to visually investigate the ...
Data-Oriented State Space Discretization for Crowdsourced Robot Learning of Physical Skills
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work discusses a crowdsourced learning scheme for robot physical intelligence. Using a large amount of data from crowdsourced mentors, the scheme allows robots to synthesize new physical skills that are never demonstrated ...
Superhydrophobic Property and Corrosion Resistance of 1100 Aluminum Alloy With Peano Fractal Micro-Nano Textures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To enhance the corrosion resistance of aluminum alloy exposed to marine environment, a novel Peano fractal micro-nano texture was introduced. The Peano micro-nano textures with three depths were prepared by laser etching ...
Polar Airstream Cyclogenesis in the Australasian Region: A Composite Study Using ECMWF Analyses
Publisher: American Meteorological Society
Abstract: Cold-air disturbances that form upstream of the main polar frontal cloud band and evolve into comma shapes are observed in almost any satellite image of the midlatitudes of the Southern Hemisphere. This study describes ...
