RISSaturation-Optimized Quasi-Sliding-Mode Calming Control of Free-Flying Space Robots Based on Model-Free Adaptive Control Theory
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a saturation-optimized, quasi-sliding-mode model-free adaptive control (SM-MFAC) method to control the postcollision calming motion of an unstable free-flying space robot with saturated output torque. ...
Instability in Nonlinear Oscillation of Dielectric Elastomers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A membrane of a dielectric elastomer oscillates when subject to AC voltage. Its oscillation is nonlinear due to large deformation and nonlinear electromechanical coupling. Dynamic instability in dielectric elastomers—the ...
Radiative Cooling Calculated by Random Band Models with S-1-β Tailed Distribution
Publisher: American Meteorological Society
Abstract: Random band models with S-l-u tailed distribution for line intensity are proposed for both the Lorentz lineprofile and an approximate Voigt line profile suggested by Zhu. Such a distribution for the weak line intensityis more realistic than a Goody...
Study of the Optical Impact of Receiver Position Error on Parabolic Trough Collectors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A newly developed analytical optical approach—firstprinciple OPTical intercept calculation (FirstOPTIC)—is employed to study the optical impact of receiver position error on parabolic trough collectors. The FirstOPTIC ...
Dissolution Dynamics and Temporal Variations of Groundwater Flux in the Subsurface Source Zone of Nonaqueous Phase Liquids
Publisher: American Society of Civil Engineers
Abstract: Widespread production and use of industrial solvents and liquid petroleum products have created problems of subsurface contamination by nonaqueous phase liquids (NAPLs). The objective of this study is to relate NAPL ...

Experimental Investigation Into the Effect of Fluid Viscosity on Instability of an Over-hung Flexible Rotor Partially Filled With Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of fluid viscosity on the developing process of the instability in an over-hung flexible rotor partially filled with fluid, the dynamical behavior of the rotor system while the ...
Three-Dimensional Effects of Solder Joints in Micro-Scale BGA Assembly
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micro-scale BGA has attracted more and more interest due to their high performance/area ratio. This technology is especially important for mobile personal equipment, such as cellular phones and ...
Carbon Dioxide 15-μm Band Cooling Rates in the Upper Middle Atmosphere Calculated by Curtis Matrix Interpolation
Publisher: American Meteorological Society
Abstract: A new algorithm for calculating CO2 15-?m band cooling rate is suggested following a similar idea proposed by Fels and Schwarzkopf in 1981. Since the Curtis matrix is more useful in cooling rate calculations, we show in ...
