Stabilization of Filament Production Rate for Screw Extrusion-Based Polymer Three-Dimensional-Printing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polymer three-dimensional (3D)-printing has been commercialized rapidly during recent years; however, there remains a matter of improving the manufacturing speed. Screw extrusion has a strong potential to fasten the process ...
Extremum Seeking for Traffic Congestion Control With a Downstream Bottleneck
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops boundary control for freeway traffic with a downstream bottleneck. Traffic on a freeway segment with capacity drop at outlet of the segment is a common phenomenon that leads to traffic bottleneck problem. ...
State Estimation for Lithium-Ion Batteries With Phase Transition Materials Via Boundary Observers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lithium iron phosphate (LiFePO4 or LFP) is a common active material in lithium-ion batteries. It has been observed that this material undergoes phase transitions during the normal charge and discharge operation of the ...
Axial Vibration Suppression in a Partial Differential Equation Model of Ascending Mining Cable Elevator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lifting up a cage with miners via a mining cable causes axial vibrations of the cable. These vibration dynamics can be described by a coupled wave partial differential equation-ordinary differential equation (PDE-ODE) ...
