Introduction: In a switch-capacitor realisation of the multiplying digitalto-analogue converter (MDAC) used in algorithmic and pipeline analogue-to-digital converters (ADCs), the settling behaviour of the opamp determines the speed and accuracy of the ADC. Fast settling requires high unity gain bandwidth, while accurate settling requires a high DC gain. As gate lengths continue to shorten, high...

Finite settling time control of the double integrator is considered. The approach taken is to design a compensator based on a virtual lossless absorber which is tuned so that, at some predetermined time, the virtual subsystem possesses all of the system’s energy. At this time the controller is turned off, and the double integrator remains at rest at the origin. This strategy gives the appearanc...

Experiments were conducted to measure the dendrite tip growth velocities of equiaxed dendritic crystals settling in an undercooled succinonitrile (SCN)-acetone melt. The tip velocities were measured as a function of the settling speed of the crystal and the Eulerian angle between the dendrite arms and the flow direction relative to the crystal. The average of the measured tip growth velocities ...

Experiments of particle-laden inclined film flow [Zhou, Dupuy, Bertozzi, and Hosoi, Phys. Rev. Lett. 94 (2005)] have displayed different settling behaviors depending on the particle concentration φ and angle of inclination θ, in which particles accumulate on the substrate or near the advancing contact line, or remain mixed. Zhou et al. presented a lubrication model that captures the qualitative...

The effect of the type of oil, types of alcohol and the alcohol concentration on the settling behaviour of glycerol during biodiesel production is discussed in the current paper. Biodiesel production was performed by transesterification using 0.58 % sodium hydroxide (NaOH) as a basic catalyst at 60°C and 20 min of reaction time. The yield of biodiesel produced in each experiment was separated f...
