The effect of an X-point and separatrix on unstable modes is considered within the context of MHD and fluid models. We begin by reviewing the magnetic flux geometry in the vicinity of the X-point and the effect it has on wave behavior. We then consider fluid models for the edge and SOL plasma based on the reduced Braginskii equations, and subsets thereof. For parameters typical of tokamak bound...

AbstructThe history, application options, and ideal basic performance of the thermionic energy converter are outlined. The basic plasma types associated with various modes of converter operation are described, with emphasis on identification and semi-quantitative characterization of the dominant physical processes and utility of each plasma type. The frontier plasma science issues in thermionic...

A three-dimensional full-wave code is newly employed to investigate the plasma production by Ion-Cyclotron Range of Frequency (ICRF) waves on GAMMA 10. The spatial structure of the excited wave fields are calculated for two types of ICRF antennas (Double Half-Turn and Nagoya Type-III) in the central cell. The plasma production by ICRF waves depends on the wave excitation in the plasma. Eigenmod...

The growing market for flexible electronics devices is asking for reduction of manufacturing process complexity. One way to reduce complexity is to decrease the number of single components of a device by using integrated modules, i.e. device components providing multiple functions. In this article, the concept of a self-powered electrochromic graphics display device is demonstrated. The device ...

Through pervasive computing, users can access information and applications anytime, anywhere, using any device. But as mobile devices such as Personal Digital Assistant (PDA), SmartPhone, and consumer appliance continue to flourish, it becomes a significant challenge to provide more tailored and adaptable services for this diverse group. To make it easier for people to use mobile devices effect...

A haptic device using flexible sheet such as rubber has already been proposed. Controlling the bias tension of the sheet, the device varies compliance of the sheet in the normal direction; users can feel compliance of various virtual objects if they touch the sheet. This device is integrated into a visual and haptic display. The haptic device uses transparent flexible sheet, and a liquid crysta...
