Mobile robots operating in real-world, outdoor scenarios depend on dynamic scene understanding for detecting and avoiding obstacles, recognizing landmarks, acquiring models, and for detecting and tracking moving objects. Motion understanding has been an active research effort for more than a decade, searching for solutions to some of these problems; however, it still remains one of the more difficult and challenging areas of computer vision research. Qualitative Motion Understanding describes a qualitative approach to dynamic scene and motion analysis, called DRIVE (Dynamic Reasoning from Integrated Visual Evidence). The DRIVE system addresses the problems of (a) estimating the robot's egomotion, (b) reconstructing the observed 3-D scene structure; and (c) evaluating the motion of individual objects from a sequence of monocular images. The approach is based on the FOE (focus of expansion) concept, but it takes a somewhat unconventional route. The DRIVE system uses a qualitative scene model and a fuzzy focus of expansion to estimate robot motion from visual cues, to detect and track moving objects, and to construct and maintain a global dynamic reference model.
The topics currently under investigation are : decomposition of complex vehicle motion into its constituent parts ; qualitative 3 - D scene modeling ; target motion
detection and tracking ; landmark recognition ; 3 - D target model acquisition and

Intended for beginners in ergodic theory, this introductory textbook addresses students as well as researchers in mathematical physics. The main novelty is the systematic treatment of characteristic problems in ergodic theory by a unified method in terms of convergent power series and renormalization group methods, in particular. Basic concepts of ergodicity, like Gibbs states, are developed and applied to, e.g., Asonov systems or KAM Theroy. Many examples illustrate the ideas and, in addition, a substantial number of interesting topics are treated in the form of guided problems.

SICICA'97 was the third symposium in the series (1992, Malaga - Spain; 1994, Budapest - Hungary). It was sponsored by the Technical Committee on Components and Instruments and was organized by the Laboratoire d'Automatique et de MicroInformatique Industrielle, Université de Savoie, on behalf of AFCET, the National Member Organization. The symposium was held in the Impérial Palace Congress Center, Annecy. 178 papers were submitted as draft papers and reviewed by the International Program Committee members who selected 117 papers coming from 25 countries. The topics covered include: the evolution of electronic components, especially mircocontrollers and digital signal processors which can be used for the implementation of instruments where intelligence is located in the processing; problems and solutions using fieldbuses for the control of automated processes; and the principal phases in the industrialisation of microsystems which associate micromechanics and microelectronics. The Symposium showed the vitality of the research in the field of intelligent instruments and components.

"Constantin Brunner (1862-1937) was a philosopher of considerable originality and importance to whom all too little attention has been paid until quite recently." "This book presents an outline of Brunner's life and personality, then proceeds to relate his philosophy to that of Plato, Spinoza, Kant, Hegel, Schopenhauer, Husserl, and Heidegger. There follows an analysis of Brunner's theory of knowledge, the framework of a complete philosophic system which, in many of Brunner's ideas, shows a similarity to that of his contemporary F. H. Bradley, often regarded as one of the greatest English philosophers." "The themes in Brunner's work that Dr. Goetz pursues include: the synthesis of feeling, knowing, and willing; the question of objective knowledge; the relationship between life and thought; the proper understanding of "egoism"; and the ultimate goal of philosophy. Devotees of Husserl and existentialists of various types may be surprised to discover just how far Brunner anticipated the major thinkers in the field of phenomenology."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

An important aspect of qualitative spatial reasoning is understanding mechanisms. This paper presents a qualitative analysis of motion for mechanical linkages. In particular, we describe how to analyze the behavior of a mechanism which has a movable axis. The basic idea of our approach is to represent relative motions of the link in terms of quadrants (qualitatively representing the direction relative to a global reference frame) and relative inclinations relative to the x-axis. Using this representation ; we can derive all the possible motions of a system of linkages. This idea has been implemented and tested on several examples.
