Stability and Performance Analysis of Time Delayed Actuator Control Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Time delay is a common phenomenon in robotic systems due to computational requirements and communication properties between or within highlevel and lowlevel controllers as well as the physical constraints of the actuator ...
Rotorcraft Hard Landing Mitigation Using Robotic Landing Gear
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A unique, beneficial feature of rotorcraft is their flexibility in aircrafttoground interfacing. For a variety of reasons, hard landings can occur when the descent rate of the aircraft is larger than intended. The resulting ...
The Hydrodynamic Drag on a Small Sphere in an Ionized Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical and experimental study was made of the hydrodynamic drag on a small sphere moving relative to a plasma in local thermodynamic equilibrium. The results have application to velocity ...
Analytical Dynamic Modeling of Line-Focus Solar Collectors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solar thermal electric power and industrial process heat systems may require a constant outlet temperature from the collector field. This constant temperature is most efficiently maintained by ...

Publisher: American Society of Civil Engineers
Discussion of “ p-y Criterion for Rock Mass” by Robert Liang, Ke Yang, and Jamal Nusairat
Publisher: American Society of Civil Engineers
Discussion of “<i>Consent to Disaster: 1977 Panama Treaties</i>” by G. Russell Evans (April, 1988, Vol. 114, No. 2)
Publisher: American Society of Civil Engineers
Chart II. Tracks of Centers of Anticyclones, July 1933. (Inset) Departure of Monthly Mean Pressure from Normal
Publisher: American Meteorological Society
Abstract: This Chart is available in the print version.
State Estimation Algorithm Based on a Disturbance Observer for a Free Piston Engine Linear Generator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to realize a thin, compact, efficient, and fuelflexible powergeneration system, we have been developing and investigating a freepiston engine linear generator (FPEG), which consists of a twostroke combustion chamber ...
Risk Assessment and Early-Warning System for High-Speed Railway during the Construction and Operation of Underpass Bridges
Publisher: American Society of Civil Engineers
Abstract: Potential risk assessment and early-warning system are essentially important to ensure the safety of high-speed railway (HSR) bridges. This paper presents an in-depth methodology of this risk assessment and early warning. ...
