The organization of the knowledge base for monitoring and the related principles for knowledge representation are presented. The knowledge base consists of conguration, sensor, dynamic and statistical databases. The con guration database represents the system architecture of the network. The sensor database is set up based on the sensor con guration in the network. The dynamic database represen...

This paper discusses the feasibility of using conguration space (C-space) as a means of visualization and control in operator-guided real-time motion of a robot arm manipulator. The motivation is to improve performance of the human operator in tasks involving the manipulator motion in an environment with obstacles. Unlike some other motion planning tasks, operators are known to make expensive m...

In this paper, we propose system support for building adaptive migratory continuous media applications in distributed real-time environments. In future distributed computing environments, various objects in homes and o ces will embed computers, and various applications will be moved between these computers according to the location of these users. These environments are considered as one of typ...

In this paper, we present the prototypical con-guration system ConBaCon (Constraint Based Conguration) and some aspects of the underlying model. Driven by the constraint-based solution model, which is responsible for a substantial reduction of the search space, ConBaCon { together with the graphical problem editor ConCreTe { allows the eecient connguration design of industrial control systems. ...

——A Bismuth-doped ber amplier (BDFA) in a double-pass conguration is proposed and demonstrated. The BDFA consists of a Bismuth-doped phosphogermanosilicate (BiPGeSiO2) ber pumped by a Titanium––Sapphire source at 810 nm. The BDFA has an amplied spontaneous emission (ASE) spectrum with a 3-dB bandwidth from 1220 to 1490 nm. The maximum gain of the proposed BDFA is 2.0 dB at an input signal ...

This thesis addresses the problem of immobilizing and manipulating parts with devices that have a mixture of discrete and continuous degrees of freedom. Immobilizing an object requires calculating the device parameters that reduce the positions and orientations of the object compatible with the contact constraints to a single point of its conguration space. Likewise, manipulating an object requ...

A method for the prediction of acoustic scatter from complex geometries is presented. The discontinuous Galerkin method provides a framework for the development of a high-order method using unstructured grids. The method's compact form contributes to its accuracy and e ciency, and makes the method well suited for distributed memory parallel computing platforms. Mesh re nement studies are presen...

This paper describ esa new search algorithm, Dual Dijkstra Search. F roma given initial and nal conguration, Dual Dijkstra Search nds various paths which have di er enttop olo giessimultaneously. This alo grithm allows you to enumerate not only the optimal one but variety of meaningful candidates among local minimum paths. It is based on the algorithm of Dijkstra[10], which is populary used to ...
