Telerobotics research for Super Long Distance has been underway between MITI of Japan and NASA JPL of United States. Foe this telerobotics, the limited amount of data transfer, communication delay and the uncertainty of robot environment will be the major issues. To overcome these problems, a telerobotic system, with a knowledge base for object handling, an environment model and a hybrid compli...

Distributed systems with high availability requirements have to support some form of dynamic reconfiguration. This means that they must provide the ability to be maintained or upgraded without being taken off-line. This thesis addresses the dynamic reconfiguration of distributed applications that run on top of an object-middleware infrastructure. In this context, a system configuration is defin...

The foundations of the eld of behavioral speci cation have matured. So, case studies are the important current topics of this eld. In our previous work, we built the behavioral speci cation of the Automated Teller Machine (ATM) system by using object composition and observable projection operators. From this experience, we noticed that this approach had the following problems: there was no good...

Learning objects-based architectures often allows the creation of coarse-granular learning resources by aggregating learning objects retrieved mainly from well-structured public repositories. Nonetheless, the learning resource building process is not exactly trivial, since proper selecting and sequencing strategies must be applied in order to make it useful for learning purposes, as well as to ...

The Sharable Content Object Reference Model (SCORM) is a profile of several elearning specification to ensure the reusability and interoperability of elearning content in web based Learning Management Systems (LMSs). Learning grids learning environments built on the technology of grid services are a promising new approach to enhance quality of elearning by overcoming the page oriented structure...

The paper presents a hierarchical object recognition system for document processing. It is based on a spatial tree structure representation and Bayesian framework. The image components are built up from lower level image components stored in a library. The tree representations of the objects are assembled from these components. A probabilistic framework is used in order to get robust behaviour....

We present in this paper a system which automatically builds, from real images, a scene model containing both 3D geometric information of the scene structure and its photometric information under various illumination conditions. The geometric structure is recovered from images taken from distinct viewpoints. Structure-from-motion and correlation-based stereo techniques are used to match pixels ...

This paper analyzes the power loss of magnetically controlled reactor based on the basic theory of the electromagnetic field. In a variety of magnetic valve structure model as the object, physical simulation models of the reactor are built. Using Ansoft Maxwell simulation software, various magnetic valve structures of the reactor are studied by the analysis of the magnetic valve type reactor co...
