In this paper, a novel method of hand tracking is introduced, which can get the depth of hand by fusing the information sampled by devices of computer vision and bend-sensors fixed on the elbow. Based on this, a new coded representation is proposed to represent the movement trajectory, which can be used in the Chinese Sign Language recognition. Experiment results have shown that the method proposed in this paper is quite effective.

IEEE International Conference on Fuzzy systems (FUZZ-IEEE)

作者： Jianqiang Yi N. Yubazaki K. Hirota Laboratory of Complex System Institute of Automation Chinese Academy and Sciences Beijing China Technology Research Center Mycom Inc. Kyoto Japan Interdisciplinary Graduate School of Science and Engineering Tokyo Institute of Technology Yokohama Japan

A fuzzy controller for backing up control of truck-trailer system is proposed based on the single input rule modules dynamically connected fuzzy inference model. The relative angle of the truck with the trailer, trailer angle, and trailer vertical position are selected as the input items. The dynamic importance degrees are set up such that the relative angle takes control priority when it becomes big. Simulation results demonstrate that the fuzzy controller backs up the truck-trailer system successfully even from a jackknife situation.

IEEE International Conference on Fuzzy systems (FUZZ-IEEE)

A stability analysis approach for a class of fuzzy controllers based on the single input rule modules (SIRMs) dynamically connected fuzzy inference model is proposed. It is proved that such a fuzzy controller can be approximately changed into a linear state feedback controller near an equilibrium point if each SIRM has a property of linear input-output mapping. Then linear state feedback control theories can be used to solve the stability problem. The proposed approach is applied to stabilization control of inverted pendulum system and the stability analysis results agree completely with the control results.

The paper deals with the extended social dilemma model "Distributed Social Dilemma". In order to emerge mutually cooperative behavior among non-altruistic individuals, we propose a solution based on the centralized organization, "meta-player". By comparison with some cases, we confirm the effect of competitive meta-players. © 2000 IEEE.

Uneven Input Space Division and Balance of Generality and Conciseness of Submodels for Hierarchical Fuzzy Modeling

引用

Journal of Advanced Computational Intelligence and Intelligent Informatics 2000年第2期4卷 152-157页

作者： Tachibana, Kanta Furuhashi, Takeshi Complex System Engineering Laboratory Department of Computational Science and Engineering Graduate School of Engineering Nagoya University Japan Bioelectronics Laboratory Department of Information Electronics Graduate School of Engineering Nagoya University Japan

Hierarchical fuzzy modeling is a promising technique to describe input-output relationships of nonlinear systems with multiple input. This paper presents a new method of dividing input spaces for hierarchical fuzzy modeling using the Fuzzy Neural Network (FNN) and Genetic Algorithm (GA). Uneven division of input space for each submodel in the hierarchical fuzzy model can be achieved with the proposed method. The obtained hierarchical fuzzy models are likely more concise and more precise than those identified with conventional methods. Studies on effects of the weights on performance indices of generality and conciseness of the fuzzy model are also shown in this paper. © Fuji Technology Press Ltd.

IEEE International Workshop on Intelligent Robots and systems (IROS)

作者： Peitao Shi Min Tan Xiaojun Ma Research Laboratory of Engineering Sciences for Complex System Institute of Automation Chinese Academy of Sciences Beijing China

In this paper, the robot force control scheme is suggested for open robot controller, which combines the force control and collision avoidance algorithms. The adaptive fuzzy control approach is selected to realize force tracking when the environment parameters are unknown and vary considerably. We design the RobForce class derived from the open robot class with C++ language. In this robot force class, we cite the virtual force approach and transform collision avoidance into the force control problem and unite it with the force control in the RobForce class. Based on the robot class library, the user can develop his/hers own robot force control system. In addition we design a software to verify the scheme and the simulation demonstrates that the robot force control scheme is simple, universal for position based robot, and is capable of force tracking regardless of wide parameter variations.

As a communication interface for handicapped people, an eye-gaze input system has been studied in the authors' research group. In their previous system, a user's head must be immobilized in its use; therefore, the usability remained at a low degree. This time, the system is combined with 3-D positioning device so that a user is able to move his/her head freely. This paper describes how the system is improved, and how better it works than the authors' previous system, according to the quantitative analysis.

He currently the program manager for the Sustainable Hardware and Affordable Readiness Practice Program (SHARP). is a Navy-wide logistics research and development prgram aimed at the successful transiton of proved technologies inot the fleet. SHARP focuses on reducing acquisition performance capability reliability maintainability and readiness of these systems. Mr. Grubb has served as a department director for the past eleven years. His most recent assignment was as director of the Tactical Computer Resources and Test Equipment Department. This organization provided acquisition and in-service engineering support of the Navy's tectical embedded computers priphirals displays and mass memory storage devices. The organization also provided a complete range of product engineering and metrology engineerig services for SSP NevSeaSysCom and the Trident Program.

In an era of fiscal austerity, downsizing and unforgiving pressure upon human and economic capital, it is an Augean task to identify resources for fresh and creative work. The realities of the day and the practical demands of more immediate fleet needs can often dictate higher priorities. Yet, the Navy must avoid eating its seed corn. Exercising both technical insight and management foresight, the fleet, the R&D community, the Office of the Chief of Naval Operations (OpNav) and the product engineering expertise of the Naval Surface Warfare Center (NSWC) are joined and underway with integrated efforts to marry new, fully demonstrated technologies and operational urgencies. Defense funding today cannot sponsor all work that can be mission-justified over the long term because budgets are insufficient to support product maturation within the classical development cycle. However, by rigorous technical filtering and astute engineering of both marketplace capabilities and currently available components, it is possible in a few select cases to compress and, in effect, integrate advanced development (6.3), engineering development (6.4), weapon procurement (WPN), ship construction (SCN), operation and maintenance (O&M,N) budgetary categories when fleet criticalities and technology opportunities can happily meet. In short, 6.3 funds can be applied directly to ''ripe gateways'' so modern technology is inserted into existing troubled or aging systems, sidestepping the lengthy, traditional development cycle and accelerating practical payoffs to recurrent fleet problems. To produce such constructive results has required a remarkable convergence of sponsor prescience and engineering workforce excellence. The paper describes, extensively, the philosophy of approach, transition strategy, polling of fleet needs, technology assessment, and management team requirements. The process for culling and selecting specific candidate tasks for SHARP sponsorship (matching operational need with t
