The last few years have witnessed an increasing interest in modular reconfigurable robotics for education, inspired robotic research, and space applications. This paper presents the latest results of the cube-M modular project. Firstly, an overview of the research achievements in modular robot is given. Then the new modular robot cube-M with one degree of freedom, an improved version of the Y1 modular robot, is presented. After that, the discussion focuses on the realization of a distributed hardware and control. Each module has embedded intelligent capabilities with an independent onboard controller to enable the realization of completely modular design. In the end, a snake-like robot prototype is built to confirm the feasibility of our design principle.

Knowledge sharing in flexible production networks: A context-based approach

International Journal of Automotive Technology and Management 2009年第1期9卷 87-109页

作者： Smirnov, Alexander Levashova, Tatiana Shilov, Nikolay St. Petersburg Institute for Informatics and Automation RAS 39 14 line 199178 St. Petersburg Russia Russia St. Petersburg State Electrical Engineering University Russia Computer Aided Integrated Systems Laboratory SPIIRAS Russia

The appearance of production supply networks can be considered as a response to changes in global markets. Networks can be seen as a step beyond the linear supply chain topography. However, when dealing with multiple organisations and multiple processes within a complicated network, identifying and locating a member that has responsibility for and/or competence in a particular part of the network can be a laborious, time-consuming process. Knowledge sharing aims to assist in solving this problem. The approach presented here is based on the application of such technologies as ontology and context management to knowledge sharing. The paper also presents the experience of applying the above approach to solving a real-life problem from the area of dynamic logistics as part of a flexible production network configuration. The considered problem takes into account a continuously changing problem environment and requires nearly real-time solving. Copyright © 2009 Inderscience Enterprises Ltd.

Event-based biosurveillance is a scientific discipline in which diverse sources of data, many of which are available from the Internet, are characterized prospectively to provide information on infectious disease events. Biosurveillance complements traditional public health surveillance to provide both early warning of infectious disease events as well as situational awareness. The Global Health Security Action Group (GHSAG) of the Global Health Security Initiative is developing a biosurveillance capability that integrates and leverages component systems from member nations. This work discusses these biosurveillance systems and identifies needed future studies.

Since Witsenhausen put forward his remarkable counterexample in 1968, there have been many attempts to develop efficient methods for solving this non-convex functional optimization problem. However there are few methods designed from game theoretic perspectives. In this paper, after discretizing the Witsenhausen counterexample and re-writing the formulation in analytical expressions, we use fading memory JSFP with inertia, one learning approach in games, to search for better controllers from a view of potential games. We achieve a better solution than the previously known best one. Moreover, we show that the learning approaches are simple and automated and they are easy to extend for solving general functional optimization problems.

Congress on Evolutionary Computation

Sanderson Nature Inspired Computation and Applications Laboratory the Department of Computer Science and Technology University of Science and Technology Hefei Anhui China Center of Automation Technologies and Systems Rensselaer Polytechnic Institute Troy NY USA CERCIA the School of Computer Science University of Binningham Birmingham UK

In this paper, we propose a new algorithm, named JACC-G, for large scale optimization problems. The motivation is to improve our previous work on grouping and adaptive weighting based cooperative coevolution algorithm, DECC-G [1], which uses random grouping strategy to divide the objective vector into subcomponents, and solve each of them in a cyclical fashion. The adaptive weighting mechanism is used to adjust all the subcomponents together at the end of each cycle. In the new JACC-G algorithm: (1) A most recent and efficient Differential Evolution (DE) variant, JADE [2], is employed as the subcomponent optimizer to seek for a better performance; (2) The adaptive weighting is time-consuming and expected to work only in the first few cycles, so a detection module is added to prevent applying it arbitrarily; (3) JADE is also used to optimize the weight vector in adaptive weighting process instead of using a basic DE in previous DECC-G. The efficacy of the proposed JACC-G algorithm is evaluated on two sets of widely used benchmark functions up to 1000 dimensions.

作者： Hengmin Zhou Daniel Zeng Changli Zhang The Key Laboratory of Complex Systems and Intelligence Science Institute of Automation Chinese Academy and Sciences China MIS Department University of Arizona Tucson Tucson AZ USA College of Computer Science and Technology Jilin University Jilin China

This paper is motivated to utilize results from opinion mining to facilitate social network analysis. We introduce the concept of opinion networks and propose a PageRank-like algorithm, named OpinionRank, to rank the nodes in an opinion network. This proposed approach has been applied to real-world datasets and initial experiments indicate that the sentiment information is helpful for finding leaders of online communities and that the OpinionRank method outperforms benchmark methods that ignore sentiment information.

Ensuring system stability in medium-voltage DC (MVDC) integrated power systems (IPS) is a key issue, due to the presence of many shipboard electric users fed by constant power load (CPL) converters. This paper presents an innovative control system aimed at utilizing alternators, connected to the IPS through controlled AC-DC interface converters, to improve MVDC stable voltage control. Such system is designed to control, for each shipboard generator, the AC machine voltage, the prime mover speed and the interface converter, in an integrated way. Technological aspects and control principle scheme of this system will be presented in the paper, with particular reference to the issue of DC-link voltage stability. This system is expected to bring advantages in terms of MVDC IPS integration, stable parallel operation of generators and loads, safe exploitation of alternators capability as a source of stabilizing power.

This paper is devoted to the consensus control for a network of autonomous agents with high-dimension linear coupling dynamics and subject to external disturbances. By transforming the consensus control problem into an H infin control problem, we propose a distributed state feedback protocol, and obtain conditions in terms of linear matrix inequalities (LMIs) to ensure the consensus with a prescribed H infin performance level for networks with zero and nonzero communication delays, respectively. Furthermore, the undetermined feedback matrix of the proposed protocol is also solved. A numerical example is included to validate the theoretical results.
