It was recently demonstrated that static, resistive, magnetohydrodynamic equilibria, in the presence of spatially-uniform electrical conductivity, do not exist in a torus under a standard set of assumed symmetries and boundary conditions. The difficulty, which goes away in the “periodic straight cylinder approximation,” is associated with the necessarily non-vanishing character of the curl of t...

The effects of resistive loads applied at the mouth were compared to the effects of bronchospasm on ventilation, respiratory muscle force (occlusion pressure), and respiratory sensations in 6 normal and 11 asthmatic subjects breathing 100% O2. External resistive loads ranging from 0.65 to 13.33 cm H2O/liter per s were applied during both inspiration and expiration. Bronchospasm was induced by i...

This paper presents the SmartFiducial, a wireless tangible object that facilitates additional modes of expressivity for vision-based tabletop surfaces. Using infrared proximity sensing and resistive based force-sensors, the SmartFiducial affords users unique, and highly gestural inputs. Furthermore, the SmartFiducial incorporates additional customizable pushbutton switches. Using XBee radio fre...

In this paper we present a novel system for tactile actuation in stylus-based musical interactions. The proposed controller aims to support rhythmical musical performance. The system builds on resistive force feedback, which is achieved through a brakeaugmented ball pen stylus on a sticky touch-sensitive surface. Along the device itself, we present musical interaction principles that are enable...

In this paper we propose a hybrid approach minimizing the active torque produced by muscles groups at the joint level. The proposed approach is hybrid in the sense that it combines the local knowledge of the external torque induced by external forces such as gravity and exerted force, and the full knowledge of the passive-resistive torque characteristics due to ligaments and connective tissues....

Ti-doped ZnO (ZnO/Ti) thin films were grown on indium tin oxide substrates by a facile electrodeposition route. The morphology, crystal structure and resistive switching properties were examined, respectively. The morphology reveals that grains are composed of small crystals. The (002) preferential growth along c-axis of ZnO/Ti could be observed from structural analysis. The XPS study shows the...

We demonstrate that spatial arrangement and optical properties of metamaterial nanostructures can be controlled dynamically using currents and magnetic fields. Mechanical deformation of metamaterial arrays is driven by both resistive heating of bimorph nanostructures and the Lorentz force that acts on charges moving in a magnetic field. With electrically controlled transmission changes of up to...
