- Ionospheric monitoring by using GEONET real-time data
- 概要
- GEONET is a Japanese nationwide GNSS reference station network maintained by Geospatial Authority of Japan (GSI). Electronic Navigation Research Institute (ENRI) has been receiving GEONET real-time data for various purposes. ENRI and Research Institute of Sustainable Humanosphere (RISH), Kyoto University have jointly developed real-time ionospheric disturbance monitoring system, and used the system for successful ionospheric sounding rocket campaign. Recently the system has been upgraded to obtain three-dimensional electron density distribution over Japan by a GPS tomography technique. The system overview will be given and possible applications of the system will be discussed.

- High Quality IP Design using High-Level Synthesis Design Flow
- 概要
- High Level Synthesis technologies has been widely used for hardware IP (Intellectual Property) designs to significantly shorten the design & verification time. However how to achieve a good PPA (Performance/Power/Area) result is still a challenge use High Level Synthesis (HLS) to find a quick path from an algorithm to a hardware IP. This talk presents our practical experiences about how to use Cadence Stratus HLS design flow to achieve a high quality IP design using interface based design, architectural exploration and congestion aware design flow.

- fJ/bit integrated nanophotonics for optical communication on a chip
- 概要
- If we look at CMOS chips, we see that they have very complicated wiring. The large numbers of resistors and capacitors in the chips lead to high latency, and vast amounts of energy is consumed to charge the capacitors in the signal lines. To solve these problems, many researchers have been trying to introduce photonics into a chip. It is well known that the bandwidth in photonics does not scale with wire length, and it can be easily expanded by using wavelength division multiplexing technology. In addition, propagating light doesn’t require energy for charging the capacitors in the signal line. However, photonics integration technology is still much less mature than its electronics counterpart. The desired footprint for photonic devices will be around several micrometers or less in the future, which is orders of magnitude smaller than that for conventional photonic ones. This talk will show that photonic crystal is a promising platform for dense photonic integration. Photonic crystal, an artificial dielectric made by using nanotechnology, is advantageous for developing various nanophotonic devices owing to its tight light confinement effect. These wavelength-scale and integratable devices are promising for dense photonic networks on a processor chip, which will enable high-performance information processing with low power consumption.

- Program derivation: history and developments
- 概要
- Program derivation is a methodology of constructing correct software. Usually, a software is first developed and then tested and/or verified so as to see its correctness. In program derivation, starting from the specification, a software is constructed by a series of correctness-guaranteeing steps. Program derivation was pioneered by Edsger W. Dijkstra in early 70’s, and after that, several proposals have been made, including strategies of embodying software and better ways of writing specifications. This talk will briefly review the history of program derivation and then introduce a recent study for developing programs that support developing incremental computing.

- 体内に埋め込んだRFID-タグの位置計測
- 概要
- The positioning system inside the human body is efficient for improving medical treatment. The current progress in the sophisticated imaging technologies such as computed tomography (CT) and magnetic resonance imaging (MRI) allow us to find a tumor with a size of less than 10mm. It is, however, sometimes difficult to determine its position during surgery operation due to the deformation of organs. We need a surgical marking system to determine the correct tumor position. A capsule endoscopy is an another application for in-body positioning systems. Although the capsule endoscopy is capable of diagnosing a disease in the small intestine, we can not point out the position at which it takes the diagnostic image. We have developed a RFID (Radio Frequency Identification)-based surgical marking system. The miniature RFID-tags are implanted near the target tumor during the diagnosis phase. The operator can determine the position of the implanted RFID tags by specially designed sensor antenna. The target RFID tags are moving due to internal organ motion. We have developed a particle filter assisted method for tracking the target RFID tags. In this speech, I will introduce some results on the RFID-tag based in-body positioning system.
