本稿では, 各コンテンツの信号特性を考慮に入れた画像符号化(コンテントオリエンティッド符号化)実現のためのシステムを提案する. このシステムは、符号化方式が異なる各コンテンツ間の連続再生を可能にする機能の提供を目的としている. そのためにサーバ·クライアント間でスケジューリングのネゴシエーションを行い, その情報を基にデコーダの動的ダウンロードを行う. ネゴシエーション機構は, JavaとCORBA(Common )によって, 実装した. したがって, システムサーバ及びクライアントは, OSもしくはハードウェア仕様から独立して利用できる. このシステムは, インターネットストリーミングだけでなく放送への適用を目標としている. また, 各コンテンツ間の連続再生実現のため, フレキシブルデコーダという概念をシステムに導入した. これは, 各デコーダ間で機能モジュールの共有化を図る物である. これにより, ダウンロードすべきデコーダのサイズを減少させ, デコーダダウンロード時間の削減が可能である.

In this paper, a network distributed monitoring system was developed to improve the interaction among the users and local service robotic system and enable a remote user to get a better understanding of what is going on in the local environment. Network monitoring system using QuickCam Orbit cameras was developed to visualize the robotic system working, and was demonstrated from June 9 to June 19 at the 2005 World Exposition, Aichi, Japan. Improvements of network distributed monitoring system have been done from practical viewpoint. This paper presents the architecture of the developed network distributed monitoring system for monitoring the state of robotic system working and the state of the aged or disabled. Robot Technology Middleware (RTM) was used in the developed system. RTM is based on CORBA (Common Architecture), so it has high scaling and inter-operating ability and facilitate network-distributed software and sharing. By using RTM, we can develop cameras functional elements as ""RT software component"", which makes application and system integration easier.

In this paper, we describe an implementation of OpenRTM-aist with a lightweight CORBA which named RtORB (Robot Technology ). RtORB has implemented in C-language and is required almost half the computational resource of omniORB4 which is most popular CORBA implementation. Then it provides the almost the same performance as omniORB4. RtORB could enable to work RT-Component on various computational platforms.

We have developed a tele-diagnosis system of echography (tele-echography system)using an Echographic Diagnosis Robot. The examiner moves the robot by using a control device at a distance from the patient and obtaining the echogram and the situation around the patient. The examiner and the patient locations are connected by a wireless local area network. Remote control is realized by the (ORB) technique. We experimentally verified possibility of our system for clinical use. The robot was safe and stable even when there was slight movement of the patient and an adult patient never felt any discomfort due to the robot weight. Remote diagnosis of echograms was proved to be possible with sufficient image quality after a skilled examiner got used to controlling the robot. Since the required bandwidth of this system was at most 1Mbps, we confirmed the ability of this system for mobile robotic telemedicine.

This paper presents a novel method of constructing a human behaviour model by attention point (AP) analysis. The AP analysis consists of two steps. At the first step, it broadly observes human behaviour, constructs rough human behaviour model and finds APs which require detailed analysis. Then at the second step, by applying time-consuming analysis on APs in the same human behaviour, it can enhance the human behaviour model. This human behaviour model is highly abstracted and is able to change the degree of abstraction adapting to the environment so as to be applicable in a different environment. We describe this method and its implementation using data gloves and a stereo vision system. We also show an experimental result in which a real robot observed and performed the same human behaviour successfully in a different environment using this model.

The computing resources of an organization or project team were often spread across many different platforms and in different locations. Recently, there has been a growing interest in distributed CAAD (Computer-Aided Architectural Design) integration due to the needs of direct collaboration among project participants. The potential for the integration of information is expected to have a tremendous impact on architecture and the construction industry. The aim of this research is to provide a new paradigm for a CAAD system by combining research on integrated CAAD applications with recent collaboration technologies. To accomplish this research objective, the proposed system has been designed and a prototype implemented to produce enough guidelines to foster interest in the development of future CAAD systems on the Internet. To this end, two different scopes of implementation are evaluated: first, global architecture and the functionality of a distributed CAAD system; and, second, the association of an architectural application to the system.

The integration of video management systems and tele-communication systems is desirable to manage all of the video images used at surgery and simultaneously share them with medical specialists at remote site. Common Architecture (CORBA) allows integration of existing subsystem regardless of their hardware, operating system and programming language with minimum engineering overhead, and maximum flexibility and performance. In these clinical applications intdgrated system enabled surgeon to manage eight medical images and operate under image of 25 frame per second on his own selecting. The surgeon became able to communicate with a medical specialist and operate under precise instruction by directly writing on a shared image. In future, we will expand this integrated display system so that specialists can instruct from multiple sites.

The competitiveness of Japan's semiconductor industry fell sharply in the latter half of the 1990s. This paper attempts to explore structural factors behind this by focusing particularly on production systems. In doing so, special attention is paid to the rapid increase in complexity of technologies and markets, a phenomenon brought about by the “self-propagating” evolution of information technologies of the semiconductor industry's own making. Such an increase in complexity calls for highly specialized knowledge⁄know-how. At the same time, it is necessary to create a mechanism for combining such knowledge⁄know-how so as to ensure its cumulative and agile generation in an integral form. Japan's semiconductor industry, however, has yet to create such a mechanism for its production system. This paper attempts to identify factors behind this and find clues toward solving the problem.

Modular component-based robot systems require not only an infrastructure for component management, but also scalability as well as real-time properties. Robot Technology (RT)-Middleware is a software platform for such component-based robot systems. Each component in the RT-Middleware, so-called "RT-Component" supporting particular robot functions, is based on Common Architecture. Unfortunately, RT-Middleware cannot manage real-time information such as periods to guarantee real-time properties. This paper presents the real-time extension of RT-Middleware, which improves real-time performance than conventional RT-Middleware. Our real-time extended RT-Middleware manages the extended RT-Components, which can manage one or multiple tasks with same or different periods. Moreover, we add real-time information to General Inter-ORB Protocol packets for scheduling packets by priority. Experimental evaluations show that our real-time extended RT-Middleware improves schedulability than conventional RT-Middleware.
