The objective of this research is to discover the rules by which the human nervous system controls the cyclic task of paddle juggling. The existence of separate feedforward and feedback control signals is hypothesized, and the feedforward control system is completely identified using tools from dynamical systems theory. Using this knowledge progress is made in identifying the feedback control s...

In this paper, the applicability of advanced heat transfer enhancement technology to a paddle dryer was discussed. A computational fluid dynamics (CFD) method used simulate condensation on inner surface paddle. The effect wettability and rotation droplet behavior studied. results showed that present CFD model could properly process vertical surface. With decrease in contact angle, filmwise turn...

The performance of the electric submersible pump (ESP) significantly affected by Gas Void Fraction (GVF). Thus, using of a Rotary Gas Separator (RGS) is a suitable solution for this issue. The performance of the RGS is function of different parameters such as geometry of impeller, rotating speed, boundary conditions, media viscosity and GVF. In this study, the influences of GVF, viscosity, ...

A cantilever type has been developed for dynamic force microscopy by the addition of a harmonic oscillator in the form of a paddle to atomic force microscopy cantilevers. These cantilevers provide resonant amplification of periodic interactions between the probe and the substrate when the laser is aligned on the paddle. The cantilevers were explored for their use in piezoresponse force microsco...

This article provides the results of a study evaluating the sampling efficiency of a flat paddle sampling device against a round surface sampling device in controlled studies. Each device is supplied with identical microbial-growth media, and laboratory studies document equivalent performance of the media in the devices. Both devices perform sampling by the same process (agar transfer of microo...

This paper discusses an evaluation of an augmented reality (AR) multimodal interface that uses combined speech and paddle gestures for interaction with virtual objects in the real world. We briefly describe our AR multimodal interface architecture and multimodal fusion strategies that are based on the combination of time-based and domain semantics. Then, we present the results from a user study...

The mechanism of voltage gating in K+ channels is controversial. The paddle model posits that highly charged voltage-sensor domains move relatively freely across the lipid bilayer in response to membrane depolarization; competing models picture the charged S4 voltage-sensor helix as being shielded from lipid contact by other parts of the protein. We measured the apparent free energy of membrane...

In this paper, we propose the first numerical study of nanotube-based torsional oscillators via developing a new multiscale model. The edge-to-edge technique was employed in this multiscale method to couple the molecular model, i.e., nanotubes, and the continuum model, i.e., the metal paddle. Without losing accuracy, the metal paddle was treated as the rigid body in the continuum model. Torsion...

We present an optimal controls algorithm to find paddle trajectories in order to control a ball in table tennis so that the resulting ball trajectory achieves a set of objectives, such as hitting a particular spot on the other side of the table. The system we wish to control is an underactuated one. It consists of both the paddle and ball state (positions and velocities), but we can only direct...
