This paper introduces a computationally efficient control scheme for safe human-robot interaction. The method relies on the Explicit Reference Governor (ERG) formalism to enforce input and state constraints in real-time, thus ensuring that the robot can safely operate in close proximity to humans. The resulting constrained control method can steer the robot arm to the desired end-effector pose (or a steady-state admissible approximation thereof) ...

Knowledge and control of mixing in batch processes can prevent yield losses during scale-up. Therefore, in this study, a new heat-mixing model based ono the measurement of the heat distribution after an applied heat pulse, is proposed. The model was developed to predict mesomixing and support scale-up, scale-down, and design and optimisation of batch reactors. The proposed model considers the influences of rotational speed, stirrer type, ...

Variance-based sensitivity indices play an important role in scientific computation and data mining, thusthe significance of developing numerical methods for efficient and reliable estimation of these sensitivityindices based on (expensive) computer simulators and/or data cannot be emphasized too much. In thisarticle, the estimation of these sensitivity indices is treated as a statistical inference problem. Two principlelemmas are first proposed ...

HypothesisEven a small fraction of nanoparticles in fluids affects the splashing behavior of a droplet upon impact on a smooth surface.ExperimentsNanofluid drop impact onto a smooth sapphire substrate is experimentally investigated over wide ranges of Reynolds () and Weber () numbers for three nanofluid mass concentrations (0.01%, 0.1%, 1%) using high-speed photography. Nanofluids are prepared by diluting a commercial Al2O3-water nanofluid in ...
