This paper describes a new software tool for high quality training/learning in the field of digital microelectronics. Its main purpose is to give insight into reliability and quality assurance technologies based on Linear Feedback Shift Registers (LFSR) and other Pseudo-Random Pattern Generators (PRPG). Various PRPG types are becoming the mainstream test generation solution used in Built-in Self-Test (BIST) structures. Taking into account complex theoretical concepts behind the microelectronics self-testing (including data coding and compression, cryptography, field theory, linear programming) it is important to effectively educate engineers in this field. The software tool we present in this paper is aimed at facilitating this goal. Unlike other similar systems, this tool facilitates study of various test optimization problems, allows fault coverage analysis for different circuits and with different LFSR parameters. The main didactic aim of the tool is presenting complicated concepts in a comprehensive graphical and analytical way. The multi-platform JAVA runtime environment allows for easy usage of the tool both in the classroom and at home. The BIST Analyzer represents an integrated simulation, training, and research environment that supports both analytic and synthetic way of learning. Due to the above mentioned facts the tool provides a unique training platform to use in courses on electronic testing and design for testability. © 2008 IEEE.

Market-based multiagent fuzzy control

Market-based multiagent fuzzy control

Conference of the North American Fuzzy Information Processing Society - NAFIPS

作者： Marcelo Silva Fernando Gomide Department of Computer Engineering and Industrial Automation Faculty of Electrical and Computer Engineering State University of Campinas Sao Paulo Brazil

This paper introduces an approach to develop distributed fuzzy control systems within the framework of market-based control. In market-based systems an artificial economy is created defining the role of consumer and producer agents and a pricing system as well. The control problem is formulated as a distributed resource allocation problem in which prices act as coordination variables to induce market equilibrium. Here fuzzy rules are used to model the behavior of the consumer and producer agents. Agents play the role of subsystem controllers. Equilibrium is found by simultaneously solving the set of fuzzy models of the agents. An example concerning a set of coupled tanks is used to illustrate the approach.

TraSer: An Open-Source Solution Platform for Cross-Company Transparency in Tracking and Tracing

引用

IFAC Proceedings Volumes 2008年第2期41卷 4493-4498页

作者： Zs. Kemény E. Ilie-Zudor M Szathmári L. Monostori Computer and Automation Research Institute Hungarian Academy of Sciences Budapest Hungary Faculty of Mechanical Engineering Budapest University of Technology and Economics

Recent trends in industrial production are marked by rapid changes in structures of collaboration or competition, as well as the spreading of customized production and more intricate customer demands regarding quality and visibility of delivery processes. All this calls for efficient means of tracking and tracing beyond company borders—a technological step which is, in principle, available, yet, it is de facto restricted to isolated proprietary solutions excluding countless small and medium-sized enterprises from their application. The EU-funded project TraSer (Identity-Based Tracking and Web-Services for SMEs) was started with the goal of overcoming these obstacles by providing a free, open-source tracking and tracing solution platform which would allow SMEs to set up and maintain tracking and tracing services across company borders requiring low costs of initial investment and operation. The paper presents main goals and envisaged results of the project.

Performance-aware power management in embedded controllers with multiple-voltage processors

Information Technology Journal 2008年第6期7卷 942-947页

作者： Xia, Feng Liu, Liping Ma, Longhua Sun, Youxian Dong, Jinxiang College of Computer Science and Technology Zhejiang University Hangzhou 310027 China School of Electrical Engineering and Automation Tianjin University Tianjin 300072 China State Key Lab of Industrial Control Technology Zhejiang University Hangzhou 310027 China Faculty of Information Technology Queensland University of Technology Brisbane QLD 4001 Australia

The aim of this research is to minimize the energy dissipation of embedded controllers without jeopardizing the Quality of Control (QoC). Taking advantage of the Dynamic Voltage Scaling (DVS) technology, this study develops a performance-aware power management scheme for embedded controllers with processors that allow multiple voltage levels. The periods of control tasks are adapted online with respect to the current QoC, thus facilitating additional energy reduction over standard DVS. To avoid the waste of CPU resources as a result of the discrete voltage levels, a resource reclaiming mechanism is employed to maximize the CPU utilization and also to improve the QoC Simulations are conducted to evaluate the performance of the proposed scheme. Compared with the optimal standard DVS scheme, the proposed scheme is shown to be able to save remarkably more energy while maintaining comparable QoC. © 2008 Asian Network for Scientific Information.

Digital watermarking has been identified as a major technology to achieve copy control and ownership protection, due to improvements in imaging technologies and the ease with which digital multimedia can be created and manipulated. In this paper we present a hybrid steganographic technique for watermarking, using SVD transform and watermark quantization.

EAEEIE Annual Conference,

作者： Heinz-Dietrich Wuttke Raimund Ubar Karsten Henke Artur Jutman Faculty Informatics and Automation Ilmenau University of Technology Ilmenau Germany Department of Computer Engineering Tallinn University of Technology Estonia

A lot of learning management systems (LMS) were developed in the last ten years since e-learning opens new possibilities in learning scenarios. They offer the possibility to watch any of the students action on the computer, but possibilities to verify the level of knowledge, a student has reached (accordingly to Bloompsilas taxonomy), are very poor. Multiple choice questions and the like can only verify lower levels in this taxonomy. In this paper we discuss a new approach in verifying higher levels of knowledge in connection with interactive teaching software and online laboratories, which are coupled to an LMS. This work is a result of eight years cooperation between the Tallinn University of Technology and the Ilmenau University of Technology.

IEEE International Conference on Systems, Man and Cybernetics

作者： Z. W. Liao Z. S. Wang S. X. Hu Faculty of Computer Science Sichuan Normal University Chengdu China School of Automation Engineering University of Electronic Science and Technology Chengdu China

In this paper, we propose a novel skeletonize method for multi width ribbon-like shapes. The two difference images with vertical and horizontal directions respectively are computed to locate the singularities of the original image. Then the gradient directions of these singularity points are computed. The skeletonization can be obtained by finding the centers of via pair wise singularity points using their gradient directions. The most attracting nature of this method is that it can handle multi width shapes, which is very difficult in conventional methods. The experimental results show that our method is a ldquogoodrdquo method closing to human conception.
