In this paper we model each 2D image as a generalized extended pseudo-symbolic picture based on the absolute spatial relationships in the image. Each generalized extended pseudo-symbolic picture can then be represented by a GEP-2D string. We combine GEP-2D strings and usual 2D strings into generalized combined 2D strings to represent 2D images in order to capture both the absolute and relative spatial relationships in the image. Then we address how to maintain the complete information about the absolute spatial relationships in the image. Picture retrieval by generalized combined 2D strings is discussed. ©2005 Copyright SPIE - The International Society for Optical engineering.

International Conference on Multisensor Fusion and Integration for Intelligent Systems (MFI)

作者： A. Mori F. Naya N. Osato T. Kawaoka NTT Communication Science Laboratories Kyoto Japan Department of Knowledge Engineering and Computer Science Doshisha University Kyoto Japan

This paper describes a type of multiagent-based distributed manipulator control in which the execution of a task involves the interaction between multiple software modules called agents. The intent of this work is to integrate a model-based approach and a behavior-based approach under a multiagent control paradigm. This paradigm is applied to a manipulator control problem without the use of inverse kinematics. A conventional manipulator is thought of as a system composed of a group of spatially distributed freedoms, each of which is independently controllable. Our manipulator control system has multiple functional agents each of which individually attempts to contribute in a positive way toward improving the degree of the given task achievement. The experimental system for multiagent-based distributed control includes a Lisp machine, two types of sensors (force/vision) and a manipulator. An attempt is made to evaluate our control paradigm by giving the system an example task that involves the end-effector movement between two points. Agents are implemented as multiple concurrent processes programmed in Lisp.

Active rules have been widely used in the modern database systems. They have provided a great contribution to the maintenance of data integrity and data consistency in database systems. They also enable the system to become active instead of passive which traditional databases do. In passive databases the queries or transactions are executed only when explicitly requested by users. Active databases contain the capability to automatic monitor the conditions which defined over the database state and the ability to take an action when the state of the underlying database changes. This paper investigates how the active rule can be triggered in a heterogeneous database system environment.

Frontiers in Education (FIE) Conference

作者： B.P. Woolf C. Poli I. Grosse E. Haugsjaa B. Riggs Department of Computer Science Center for Knowledge Communication Belgium Department of Mechanical and Industrial Engineering College of Engineering University of Massachusetts Amherst MA USA

Our group at the University of Massachusetts has built design for manufacturing (DFM) computer modules which instruct students on efficient procedures for designing parts for manufacture. The goal is to assist engineering students to gain a deeper understanding of the interaction between features of a part being designed and the corresponding manufacturing requirements of the part in the domains of injection molding and sheet metal stamping. We provide animated sequences of the processes indexed according to the possible designs. The tutors allow students to select a restricted set of parts for manufacture and demonstrate the tooling complexity through both 2D animations and 3D animations. An underlying internal representation of the part being designed provides a non-intrusive critique mechanism to provide feedback to the student.

It is well known that extracting parallel loops plays a significant role in designing parallelizing compilers. The execution efficiency of a loop is enhanced when the loop can be executed in parallel or partial parallel, like a DOALL or DOACROSS loop. This paper reports on the practical parallelism detector (PPD) that is implemented in PFPC (a portable FORTRAN parallelizing compiler running on OSF/1) at NCTU to concentrate on finding the parallelism available in loops. The PPD can extract the potential DOALL and DOACROSS loops in a program by invoking a combination of the ZIV test and the I test for verifying array subscripts. Furthermore, if DOACROSS loops are available, an optimization of synchronization statement is made. Experimental results show that PPD is more reliable and accurate than previous approaches.

This paper reports the application of evolutionary computation in the automatic generation of a neural network architecture. It is a usual practice to use trial and error to find a suitable neural network architecture. This is not only time consuming but may not generate an optimal solution for a given problem. The use of evolutionary computation is a step towards automation in architecture generation. In this paper a brief introduction to the field is given as well as an implementation of automatic neural network generation using genetic programming.< >

For problem solving in the artificial intelligence, this paper presents a new hyper-distributed hyper-parallel approach based on the bifurcations and synchronizations of the hierarchical distributed chaotic dynamic systems. By using Chua's circuits arrays, the realization of the hyper-distributed hyper-parallel heuristic algorithms for real-time search of any implicit AND/OR graph is discussed. The approach not only combines the advantages of both the traditional sequential symbolic logic and the conventional neural network approaches, but also overcomes their drawbacks in many respects.< >

The concept of a simulation environment combines different aspects of the simulation process into one complete powerful tool. The environment should provide the necessary state-of-the-art advances and concepts that a modeler may require during the simulation development and execution process. The "environment" requirements must address the end user needs while minimizing the necessity of learning a new language. The requirements must specify the useful features, independent of different platforms and implementation languages. Hence the opportunity exists for standardization of environments. The paper opens a discussion on challenges and rewards awaiting the simulation community with the advent of a standard environment.
