Nowadays the maintenance of production systems requires assistance of in formation technologies because of the decrease of expert workers We have presented remote maintenance mechanism which uses agents to diagnose facili ties in the factory But there is no distinguished mechanism and environment for automatic agent invocation We have proposed spatial programming for this purpose We noticed tha...

Email is a convenient tool, however, it is still difficult for elderly people and kindergarten children. If they can learn to use it, their ability to communicate may be remarkably increased. Therefore we developed two kinds of email software ‘Gin-Mail’ for elderly people and ‘Ocha-Mail’ for kindergarten children. They adopt a pen-based interface with a tablet PC. Users write email using Ink fu...

In this paper, we propose a new execution trace driven simulation technique, called the Resource Conflict Methodology (RCM), for modeling and simulating computer systems early in the design cycle. By using a simplified hardware element model which allows the user to easily add or delete hardware elements in the model, RCM allows the user to readily change the machine design being investigated a...

With the robotic exploration of the Solar System well underway, a logical next step is the development of spacecraft capable of exploring the regions beyond the orbit of Pluto (e.g., the Kuiper Belt and the Oort Cloud), or capable of exploring in situ the nearer extra-solar planetary systems. Barring unforeseen advances in propulsion and communications technologies, the mission times for such v...

Space macrofacilities will be larger, more complex, sometimes fragile and often less accessible than the satellites and space stations of today. The need is for AIM robots to assemble, inspect, and maintain such facilities, but significant technical challenges exist. This paper profiles early results towards extensive, constrained, and humanoid approaches to AIM robots. Like the visionary facil...

Half-space depth (also called Tukey depth or location depth) is one of the most commonly studied data depth measures because it possesses many desirable properties for data depth functions. The data depth contours bound regions of increasing depth. For the sample case, there are two competing definitions of contours: the rank-based contours and the cover-based contours. In this paper, we presen...
