A fuzzy rule based approach for extracting ridge lines from digital terrain elevation data (DTED) and digital elevation model (DEM) is presented. The algorithm consists of three major steps: Fuzzy rule based classification of the elevation data, ridge pixel detection from the pixel class under consideration, and filtration of unwanted pixels. The algorithm was tested on different DTED level 1 files and digital elevation model (DEM) and works well for both.

These days, the development of computer devices leads to computer user explosion. On the other hand, conventional technology cannot handle user diversity, because the computer cannot treat each user's subjectivity. It is important to materialize techniques which can answer the user's subjective requests flexibly for the coming new media epoch. The article focuses on studying how subjective impressions are grounded in physical perceptions, especially in visual perception. We propose a model for subjectivity and physical perceptions, and give an example in an image database system.

The use of multi-agent systems to model and control complex domains is increasing. The application of multi-agent systems to distributed real-world domains motivates the development of domain independent agent architectures to foster the re-use of existing research. A domain independent agent architecture is defined as a set of representations, reasoning mechanisms and algorithms that can be used to define the behavior of an agent. Ideally, a classification method for agent architectures should ease the process of requirements matching between domains and architectures by allowing system designers to understand the relationship between domains and architectures. This paper presents the need for a classification schema and proposes a starting point for future discussion. The Sensible Agent architecture is then introduced within the classification schema. Sensible Agents perceive, process, and respond based on an understanding of both local and system goals. The core capabilities and internal architecture of a Sensible Agent is given as an example of how accurate specifications can help foster the re-use of research. © Springer-Verlag Berlin Heidelberg 1998.

A multi-agent system (MAS) can be viewed as a group of entities interacting to achieve individual or collective goals. Communication is a central issue in this interaction between agents. This paper uses the COOL language to define an extended version of the contract net protocol to address issues in one particular MAS-sensible agents. The proposed implementation of our protocol and its use in the sensible agent testbed is also discussed.

Adaptive stabilization of neural control for robot traj ectory tracking

Tsinghua Science and Technology 1998年第3期3卷 1149-1154页

A neural network (NN)-based adaptive control law is proposed for the tracking control of an n-link robot manipulator with unknown dynamic nonli nearities. Basis ftnction-like nets are employed to approximate the plant nonli nearilties, and the bound on the NN reconstruction error is assurred to be unknown. The proposed NN-based adaptive control approach integrates an NN approach with an adaptive implementation of discrete variable structure control with a simple estimation law to estimate the upper bound on the NN reconstruction error and an additional control input to be updated as a function of the estimate. Lyapunov stability theory is used to prove the uni form ultimate boundedness of the tracking error.

This paper discusses the swing-up control of a two link robot mechanism known as the Acrobot. Previously, a technique using meta-rules was proposed to compensate for external disturbances when using a dynamic fuzzy controller. In this paper, stability of the meta-rule system is analyzed from a global asymptotic stability viewpoint based on fuzzy characteristic matrices. These matrices are generated from the first phase of a three phase learning process involving the combination of genetic algorithms, dynamic switching fuzzy systems, and meta-rule techniques with the purpose of developing a better performing fuzzy controller.

Patients with sustained ventricular tachycardia and ventricular fibrillation have a potential for sudden death. After myocardial infarction the chance to get sustained ventricular tachycardia or ventricular fibrillation increases, thus reduction in number of sudden death requires advanced predictive procedures. In this study, frequency domain feature extraction, clustering and classification models are combined for providing an integrated system for the sustained ventricular arrythmias. The radial basis function network and the fuzzy c-means algorithm for training clustering and classification were investigated. These techniques do not have limitation of the previous classical procedures. The value of sensitivity and specificity, on the data was used here, for the RBFN were found to be 92.3% and 71.4%, respectively, also the value of sensitivity and specificity for the PCM were found to be 84.6% and 71.4%, respectively.

Proposes a robust visual servoing scheme for robot manipulator with eye-in-hand camera configuration. To perform the tasks defined in the image plane, the velocity Jacobian matrix is used to transform the camera motion to the object position change. In addition, a dynamic learning controller is designed to improve the tracking performance of robotic system. The proposed control scheme is implemented for tasks of tracking moving objects and shown to outperform the conventional visual servo system without the dynamic control loop in convergence and robustness to parameter uncertainty, disturbances, low sampling rate, etc.

The manufacturing of complex products often involves the assembly of other products, or sub-assemblies. Furthermore, these sub-assemblies may be manufactured by different suppliers. As a result, the specification of the assembly process for the final product contains relationships between multiple supply chain components, including business entities, manufacturing processes, products, and parts. This specification, involving the coordination and arrangement of supply chain components to support final product assembly, is referred to as a supply chain configuration. A supply chain configuration tool is used to recognize and modify the relationships between these components. Users of this tool may be engineers, purchasing agents, program managers, or other personnel concerned with the configuration's dependencies. The focus of this paper is on the development of such a tool and its use from the perspective of a purchasing agent. © 1997 by ASME.
