This paper proposes a fuzzy-neural network for fault detection and diagnosis applications. By combining certain Soft Computing (SC) and Hard Computing (HC) methodologies, an adaptive modeling scheme is developed. Our network model is an extension of the Radial Basis Function Network (RBFN). We use the efficient General Parameter (GP) approach for our learning algorithm and structure determination of the developed fuzzy-neural network. As the resulting network needs only fuzzy inference and GP computations, its computational burden is moderate. The developed fault diagnosis system is self-organizing and self-learning. In order to illustrate the performance of the proposed scheme, it is experimentally applied to fault detection of automobile transmission gears.

An efficient strategy based on an artificial neural network is presented to enable a mobile robot to move autonomously and build a rough map of its environment. The paper describes a technique based on a neural network which uses data from sonars to recognize features online. Our method is systematic, simple and yields very good results. Moreover, it is generalizable in the sense that one can train the robot to recognize particular features of interest. We have implemented and tested this technique successfully on-board a mobile robot which uses a 68332 processor and does not have support for floating point arithmetic and file structure. Once trained, the robot can recognize the features on the fly and react to them appropriately.

In electronic commerce, a satisfying buyer experience is a key competitive element. We show new techniques for better adapting interaction with an electronic catalog system to actual buying behavior. Our model replaces the sequential separation of needs identification and product brokering with a conversation in which both processes occur simultaneously. This conversation supports the buyer in formulating his or her needs, and in deciding which criteria to apply in selecting a product to buy. We have experimented with this approach in the area of travel planning and developed a system called SmartClient Travel which supports this process. It includes tools for need identification, visualization of alternatives, and choosing the most suitable one. We describe the system and its implementation, and report on user studies showing its advantages for electronic catalogs. Copyright ACM 2000.

We seek to build CIS research systems within a flexible, open architecture. In this paper, we outline our solutions to the problems of system design, construction, and integration in this environment: building distributed, modular systems for sensing, control, and processing. Based on our experience building these systems, we utilize distributed network architectures, modular software components, and intelligent object distribution to maximize flexibility while complying with the particular needs and interfaces of specific components. While a work in progress, these approaches have been integrated into several systems in development and have demonstrated significant utility, based on construction time and system flexibility. This paper will discuss the first two aspects: modular software and basic network architectures, while intelligent object distribution is presented in a companion paper. Based on the applications we have targeted and technologies we have used, this paper introduces our architecture and its components. It then presents the system’s current state and finally, discusses plans for future improvements and extensions. © Springer-Verlag Berlin Heidelberg 2000.

By now, intelligent agents have been on the research agenda of the computer science community for roughly one decade. Still, control architectures for autonomous intelligent systems have been an important research issue for an even much longer time, going as far back as James Watt’s steam engine control mechanism based on mechanical feedback. More recent work includes the development of mathematical models for control in the field of cybernetics (most notably, Wiener). Also, arguably one of the biggest contributions of more than forty years of research in Artificial Intelligence were methods and architectures aiming to describe, control, and adopt intelligent autonomous systems.

Dense range image smoothing using adaptive regularization

Dense range image smoothing using adaptive regularization

IEEE International Conference on Image Processing

作者： Yiyong Sun Joon-Ki Paik J.R. Price M.A. Abidi Department of Electrical and Computer Engineering Imaging Robotics and Intelligent Systems Laboratory University of Tennessee Knoxville USA Department of Image Engineering Graduate School of Advanced Imaging Science Chung-Ang University Seoul South Korea

We propose an adaptive regularization algorithm for smoothing dense range images using a novel, first order stabilizing function. The stabilizer we suggest is based upon minimizing the reconstructed surface area and is derived in the native, spherical coordinate system of the range scanner. This allows adjustments to be made along only the direction of measurement, thereby preventing the data overlapping problem that can arise in dense images. Adaptation is achieved by adjusting the regularization parameter according to the results of 2D edge analysis. Results indicate effective noise suppression along with well preserved edges and details in the reconstructed, 3D surfaces.

Strong practical stability for a class of 2D linear systems

Linear repetitive processes are a distinct class of 2D linear systems of both theoretical and practical interest. The stability theory for these processes currently consists of two distinct concepts termed asymptotic stability and stability along the pass respectively where the former is a necessary condition for the latter. Recently applications have arisen where asymptotic stability is too weak and stability along the pass is too strong for meaningful progress to be made. This paper develops the concept of strong practical stability for such cases.

Designing a parallel computer would be much easier if one interconnection network was for all applications and platforms. However, unfortunately, no such network exists. For a fixed application domain and fixed platform, selecting the best network can be difficult because many performance metrics and costs could be used. We discuss performance problems for interconnection networks, and describe performance metrics and performance modeling of interconnection networks from three aspects: analytical modeling, simulation modeling and empirical modeling. We also analyze the limitations and advantages of these models.

3D interpretation of sewer circular structures

3D interpretation of sewer circular structures

IEEE International Conference on robotics and Automation (ICRA)

作者： M. Kolesnik G. Baratoff Institute for Autonomous Intelligent Systems Sankt Augustin Germany Neural Information Processing Lab Department of Computer Science University of Ulm Albert-Einstein-Allee Ulm Germany

A practical algorithm for 3D interpretation of images taken in a sewer by a robot-inspector is presented. Modern sewers made of concrete present regular circular structures originating at the pipe ends as well as at the joints of the pipe sections. These pipe ends and joints provide regular marks on the sewer images and can be used for their 3D interpretation. The key idea of the paper is to extract from their image projections the 3D orientations of the circular structures and their distances relative to the robot. We adopt for this purpose a formula for the possible position of a calibrated camera on the basis of the image of a circle of known size. We describe a sequence of image processing operations that perform circle extraction, robust conic fitting and distance calculation based on original images. The reported results are preliminary in the framework of the project aimed at developing an autonomous robot for sewer inspections. We intend to use the approach to facilitate the orientation of the robot while moving in the sewer.

Fault Detection of Automobile Transmission Gears Using General Parameter Methods

Journal of robotics and Mechatronics 2000年第6期12卷 702-705页

作者： Dote, Yasuhiko Ovaska, Seppo J. Department of Computer Science and Systems Engineering Muroran Institute of Technology 27-1 Mizumoto-cho Muroran050-8585 Japan Institute of Intelligent Power Electronics Helsinki University of Technology Otakaari 5 A FIN Espoo02150 Finland

This paper compares the performance of nonlinear Radial Basis Function Network-based (RBFN) and linear AutoRegressive (AR) model-based General Parameter (GP) methods in a fault detection application. We use the efficient GP approach for initializing the weights of the RBFN model in the beginning of the off-line system identification phase, as well as for fine-tuning the modeling accuracy of RBFN and AR models on-line. Our fault detection scheme is based on monitoring the expectation value of the scalar general parameter. This provides improved robustness and detection sensitivity over such methods where the on-line prediction error is used directly in the decision making process. In order to illustrate the performance of the proposed nonlinear and linear schemes, they are applied to fault detection of automobile transmission gears. As the acoustic sound level time-series, providing the necessary basis information for fault detection, is slightly nonlinear, the GPRBFN outperformed the linear methods: the GP-AR method and conventional AR inverse filtering. Both of the GP-based methods provide competitive solutions for real-world fault detection and diagnosis applications. © 2000, Fuji Technology Press. All rights reserved.
