RISActive Mixing Nozzle for Multimaterial and Multiscale Three-Dimensional Printing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multiscale and multimaterial three-dimensional (3D) printing is new frontier in additive manufacturing (AM). It has shown great potential to implement the simultaneous and full control for fabricated object including ...
Cordon Pricing Scheme Based on Macroscopic Fundamental Diagram and Distance
Publisher: ASCE
Abstract: To alleviate traffic congestion in key areas, such as city centers, this study proposes an optimal pricing strategy that is based on the distance that users travel in a given cordon. The proposed strategy is derived from ...
Mechanics of SWCNT Aggregates Studied by Incremental Constrained Minimization
Publisher: American Society of Civil Engineers
Abstract: The stress-strain behavior of short single-walled carbon nanotube (SWCNT) aggregates is investigated by a novel incremental constrained minimization approach. An AIREBO potential is used to model the interactions within ...
Evaluation of a Horizontal Lifeline System Used during Installation of Residential Roofs
Publisher: American Society of Civil Engineers
Biaxial Compression Behavior of Concrete under Repeated Loading
Publisher: American Society of Civil Engineers
Abstract: The primary objective of this study was to investigate the behavior of concrete subjected to repeated biaxial compressive loading. Square plate specimens of concrete were tested under in-plane repeated loading that included ...
Vibration Effects Attributable to Driving of PHC Pipe Piles
Publisher: American Society of Civil Engineers
Abstract: To ensure the safety of adjacent 16.7-m-high concrete frame structures (cooling towers) and buried pipelines in service during installation of 83 prestressed high-strength concrete (PHC) pipe piles, the behavior of the ...
A Velocity Measurement Technique for Tornado Vortex Simulators
Publisher: American Meteorological Society
Abstract: A technique utilizing stereo-photogrammetry of neutrally buoyant bubbles in a tornado vortex chamber (TVC) is described. This technique is advantageous over others inasmuch as it is nonintrusive and does not require the ...
VORTICITY TRANSFER AS RELATED TO THE DEVELOPMENT OF THE GENERAL CIRCULATION
Publisher: American Meteorological Society
Abstract: The mechanism of the development and maintenance of the zonal circulation of the atmosphere is discussed from the point of view of vorticity transfer by atmospheric disturbances. Because the disturbances with vorticity ...
A Constant Force Compliant Gripper for Handling Objects of Various Sizes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the design, simulation, and testing of a compliant gripper that can provide a constant gripping force to handle objects of various sizes. Maintaining a proper gripping force is challenging when manipulating ...
Linear Variable Stiffness Mechanisms Based on Preloaded Curved Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A machine with an internal variablestiffness mechanism can adapt its output force to the working environment. In the literature, linear variablestiffness mechanisms (LVSMs) are rarer than those producing rotary motion. ...
