Project FEELEX: adding haptic surface to graphics

Abstract: This paper presents work carried out for a project to develop a new interactive technique that combines haptic sensation with computer graphics. The project has two goals. The first is to provide users with a spatially continuous surface on which they can effectively touch an image using any part of their bare hand, including the palm. The second goal is to present visual and haptic sensation simultaneously by using a single device that doesn't oblige the user to wear any extra equipment. In order to achieve these goals, we designed a new interface device comprising of a flexible screen, an actuator array and a projector. The actuator deforms the flexible screen onto which the image is projected. The user can then touch the image directly and feel its shape and rigidity. Initially we fabricated two prototypes, and their effectiveness is examined by studying the observations made by anonymous users and a performance evaluation test for spatial resolution.

Traveling wave thermoacoustic engine in a looped tube

Abstract: We have built a thermoacoustic engine consisting of a differentially heated stack of plates in a looped tube and observed spontaneous gas oscillations of the traveling wave mode running around the loop. Stability boundary and thermally produced acoustic power are compared with those for the engine tested in a resonator. The engine in a looped tube acts as a traveling wave power amplifier, whose onset temperature ratios are significantly smaller than those for the engine in a resonator.

Role of membrane transport in metabolism and function of glutathione in mammals.

Abstract: Glutathione I occurs in almost all living organisms, and its multifunctional properties have been attracting interest of many biochemists, physiologists, pharmacologists as well as clinical scientists. GSH 1 is a tripeptide with a structure of 7-L-glutamyl-Lcysteinylglycine, which is characterized by the yglutamyl peptide and the reactive thiol group. GSH is synthesized in two steps catalyzed by 7-glutamylcysteine synthetase [EC 6.3.2.2] (reaction 1) and glutathione synthetase [EC 6.3.2.3] (reaction 2), respectively.
