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 ...

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 ...

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 ...

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 ...

Abstract: This Chart is available in the print version.

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 ...

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. ...
