In ITS (intelligent transport systems), driving support systems for a driver is very important. The paper aims at providing the driver with blind spot information, in advance, taking his intention into consideration in a commuter system considered as one realization form of ITS. For such a system. we propose a "distributed sensory-intelligence architecture," which is an architecture that interconnects multiple sensory-intelligence agents. These sensory-intelligence agents are arranged in an "intelligent space" and interact to provide support for drivers. Through experiments we showed that the proposed "distributed sensory-intelligence architecture" enables valuable driving-support information to be provided to the driver by combining re-composition of environmental information with recognition of the driver's intention. © 2000 IEEE.

Water shock Hugoniot measurement up to less than 1 GPa

AIP Conference Proceedings 2000年第1期505卷 65-68页

作者： Kunihito Nagayama Yasuhito Mori Katsuya Shimada Motonao Nakahara 1Department of Aeronautics and Astronautics Graduate School of Engineering Kyushu University Hakozaki Fukuoka 812-8581 Japan 2Department of Computer and Communication Engineering Faculty of Engineering Fukuoka Institute of Technology Fukuoka 811-0295 Japan

Shock Hugoniot compression curve for water has been measured up to less than 1 GPa. Plane and steady shock wave is produced in water by the flat plate impact of a projectile accelerated up to 500m/s by a compressed gas gun. To measure shock Hugoniot in this pressure range in higher precision, a new experimental procedure was proposed, which is based on the very large pressure dependence of the refractive index of water upon compression. By using this method, shock compression curve was determined. It was confirmed that within the pressure range covered in this experiment, shock-particle velocity Hugoniot can be described by a linear relation with a large slope. Shock temperature was calculated by using the obtained Hugoniot data combined with the values of thermodynamical variables.

Constraining an interpolating curve to be bounded in a given region is an important task in curve design. In (Qi Duan et al., 1999) the rational cubic spline with a linear denominator has been used to control the interpolating curves to be bounded in the given region, but it does not work in some cases. This paper deals with the weighted rational cubic spline with a linear denominator for this kind of constraint, the sufficient condition for controlling the interpolating curves to be bounded in the given region are derived. An example is given which shows that the constraint which cannot be done by the rational spline defined in (Qi Duan et al., 1999) could be achieved by the weighted rational spline. © 2000 IEEE.

An approach for high-yield requirements capture for e-commerce and its application

Web-based e-commerce software is typically real-time, responsive, and distributed software that must meet high quality requirements. Moreover, because of its Internet-based operating environment, e-commerce software must deal with concurrency, synchronization, and non-deterministic issues (such as delays) primarily caused by the heavy usage load and underlying network conditions. In this paper, we introduce a generic, cost- effective approach to optimize requirements capture (and subsequent development and testing) with respect to functional coverage and customer perception of quality. This high-yield approach is presented and illustrated by application to an e-commerce online shopping system and used to explain the principles of use-case requirements captured in the unified modeling language. © Springer-Verlag 2001.

There is a limit of recognition performance for dialogue speech using acoustic models built only with read speech, because various acoustic and linguistic phenomena, which reflect, the characteristics of spontaneous speech, are observed in the dialogue speech. In this paper, we investigated the differences of acoustic properties which cause the limit among isolated words, read speech and spontaneous speech. Firstly, the dialogue speech was compared with the read speech through acoustic analyses. Next, the acoustic models were separately built with each of the speech databases. The recognition performance was experimentally evaluated using the acoustic models and the relations of the differences of the performance to those of the acoustic features observed in the analyses were investigated quantitatively. The effectiveness of speaker adaptation was also investigated in the same manner.

The importance of Raman Spectroscopy in the characterization of single-walled carbon nanotubes (SWNTs) is emphasized. In particular, resonant Raman spectroscopy, performed using several laser excitation energy lines, explores both the vibrational and the electronic properties of the carbon nanotubes giving a broad picture of their characteristics. This work summarizes the main results obtained in the first-order and anti-Stokes Raman spectral regions.

This paper presents a presentation semantic model that is based on the augmented transition network (ATN) for asynchronous distance learning system called Java-based Integrated Asynchronous Distance Learning (JIADL) system. The JIADL system can support diverse asynchronous distance learning services. Unlike most related work in the literature, we integrate RealPlayer and Java technology so that the superiority of both models can be complemented. A course sample is illustrated to validate the effectiveness of the paradigm proposed. How to use the proposed multimedia ATN model to model the diverse requirements of a distance learning multimedia presentation is also discussed. The multimedia ATN model is powerful in modeling the asynchronization for distance learning multimedia presentations. Furthermore, in addition to supporting asynchronous distance learning, our system can be applied to a wide range of potential value-added applications.

Assembling is one of the important factors in our daily life. The aim of assembling is to obtain a particular function from the subassembly which is generated by putting some parts together. This fact shows that assembling machine parts is possibily the most appropriate example to exeute. If we assemble some machine parts, we decide the positions by their shapes, and then, make sure both the state of parts by reaction force fed back to the hand when a part touches other parts and the behavior of the subassembly. In addition, it is advisable to use both hands for assembly. In this research, we constructed a virtual work space using a force display which give s us haptic sensation returned from not only assembling operation but collaboration with both hands. © 2000, Fuji technology Press.

The Tibet air-shower array operating at Yangbajing (4300 m above sea level) is sensitive to gamma-ray air showers at energies as low as 3 TeV. The observation of the Moon’s shadow has provided a direct check of the angular resolution, the energy estimation and the systematic pointing error of this air-shower array. Using these data, we have searched for multi-TeV gamma-ray emission from 27 SNRs located within 10 kpc distance in the declination band of −10° to +70°. The signal from the Crab Nebula was detected at 5.5 σ level. The intensity observed is (4.61±0.90)×10−12 cm−2 s−1 TeV−1 at 3 TeV. No significant DC excess was found from any of these SNRs except from the Crab Nebula.
