Research on Coalition Formation in Achieving Compatibility

Pages 31-35
Author Huei-Chen HsuYa-Li ChungHui-Chun Cha
Abstract There is one thing most people seem to know about standardization: It is slow. From a user’s perspective, the competing technologies may present spurious differences that increase uncertainty, and create transaction costs. Established industry-wide standard development organizations (SDOs) may be slow to act, bureaucratic, and inflexible to changes in users’ needs and new opportunities; consortia speed up the process of standardization. The paper aims at the consortia do indeed tend to correct these coordination failures. One thing is for sure: one part of standardization system requires a certain degree of revision and innovation.

Abstract In this paper we have modeled magnetic nanoparticle mathematically and have utilized a semi-classical approach based on Landau–Lifshitz Gilbert (LLG) equations. Our approach has based on Finite Element Method (FEM) as a numerical technique for finding approximate solutions of partial differential equations (PDE). The solution approach is based either on steady state problems, or rendering the PDE into an approximating system of ordinary differential equations, which are then numerically integrated using standard techniques. The proposed model has applied to three kind of magnetic nanoparticles including FluidMAG-DXS, FluidMAG-CMX and FluidMAG-PEI. Then Received Signal Strength (RSS) localization is utilized to find the true location of tumor where nanoparticles attached to it. The results of simulation prove that the error location can be less than 0.1 Cm. Researchers and clinicians can take advantage of these results in order for nanotechnology to make an impact in the diagnosis and treatment of malignancy. Furthermore the proposed model for magnetic nanoparticles can be used in improvement of drug delivery, cancer detection, diagnosis, imaging, and therapy while reducing toxicity.

Design and Fabrication of Multi-Function Controlling IC for Full Resolution Stereo Display

Pages 45-55
Author Jian-Chiun Lio
Abstract In this paper, I propose a new type of multi-function controlling integrated circuit (IC) for full resolution time sequential 3D display with light-emitting diode (LED) strobe backlight signal processing and optical shutter glasses. Each shutter is synchronized to block the unwanted image and transmit the wanted image. 120Hz liquid-crystal display (LCD) and an LED dynamic backlight are used to implement a multi-viewer time multiplexed 3D display. The scanning or the strobe of the dynamic LED backlight is driven by the same vertical synchronization signal. Testing results of the proposed dynamic backlight are presented and compared with results obtained by the traditional backlight type.

HighPerformance Visual Monitoring System For IKAROS

Pages 57-65
Author Shinnichi KimuraMasato TerakuraHirotaka Sawad
Abstract Recent advances in space system design have led to increasingly complex spacecraft and mission objectives, and hence, both telemetry and visual data are important for monitoring such systems for space activities. The Interplanetary Kite-craft Accelerated by Radiation of the Sun (IKAROS) spacecraft was launched on May 21, 2010; with the mission to evaluate the performance of solar power sails which are large membranes that utilize sunlight for propulsion. The visual monitoring system for IKAROS must be small, low-cost, and intelligent. For this purpose, a very small, high-performance image processing unit (HP-IMAP) has been developed based on commercial off-the-shelf technologies. This unit has a calculation capability of 500 million instructions per second in a single 50 mm×50 mm printed circuit board, and incorporates various types of interfaces using field-programmable gate array technology. This visual monitoring system was launched with IKAROS and has successfully supported IKAROS operations. Using HP-IMAP, we have successfully achieved the world’s first images taken by a spacecraft itself. In this paper, the outline of HP-IMAP for IKAROS has been depicted and the results obtained have been presented using this system on IKAROS.

Compact Circularly Polarized Low-Profile Agility GPS Antenna Based on Liquid Crystals

Pages 67-71
Author Missaoui SayedSihem MissaouiMohsen Kaddou
Abstract In this article, the design of a novel compact circular-polarization (CP) microstrip agile antenna based on Liquid Crystals (LCs) is presented. LC provides the all-in-one solution for such integration approach in terms of high quality dielectric for high performance multiband passive design and increases the peak gain and low insertion loss for GPS antenna. To benefit from LC anisotropy and thus obtaining frequency agility, a bias voltage is applied. The antenna is CP by means of the single feed technique with a truncated segment set to the edge of the patch with two orthogonal pairs of irregular and unsymmetrical slits. The simulated results are compared with experimental data, and good agreement is obtained.
