Along with uninterrupted progress of computer network technology, the application of Internet is increasingly abroad. Due to the variety of Internet environment, the corresponding software systems are more complex, and present many new characteristics. The development of complex software systems has not applied the development mode of object-oriented and component-oriented. Therefore people bring forward agent-oriented software engineering (AOSE) and software development methodology based on self-adaptive multi-agent systems. AOSE adopts the software engineering mechanism and method, including high level abstract, natural modeling, system organization and problem decompounding, etc. It can manage and control the complexity of software system, and is a kind of novel software development pattern. The paper discusses the self-adaptive mechanism of self-adaptive multi-agent systems, the software development process of self-adaptive multi-agent systems, the modeling method of self-adaptive agent modeling language and agent UML. Taking "International Conference Management System" as a case, and describes the development process of self-adaptive multi-agent systems.

We previously proposed a two-stage binaural speech enhancement with Wiener Filter (TS-BASE/WF) approach for hearing aids in adverse environments [6]. In TS-BASE/WF, the interfering signal is estimated by cancelling the target signal through an adaptive filter in the first stage and a time- variant Wiener filter is applied to enhance the target signal in the second stage. In this paper, we introduce an interference compensation approach, which is applied to the adaptive-filter output, to further improve the estimation accuracy of the interfering signal. The performance of TS-BASE with different speech enhancers is then investigated in different conditions. Experimental results show that the improved TS-BASE algorithms with interference compensation outperform the original TS-BASE algorithms, and that TS-BASE/WF gives the higher speech enhancement performance over the improved TS-BASE algorithms with other speech enhancers.

In this paper, we extend the observer/control strategies previously published in [25] to an n -link, serially connected, direct drive, rigid link, revolute robot operating in the presence of nonlinear friction effects modeled by the Lu-Gre model. In addition, we also present a new adaptive control technique for compensating for the nonlinear parameterizable Stribeck effects. Specifically, an adaptive observer/controller scheme is developed which contains a feedforward approximation of the Stribeck effects. This feedforward approximation is used in a composite controller/observer strategy which forces the average square integral of the position tracking error to an arbitrarily small value. Experimental results are included to illustrate the performance of the proposed controllers.

This paper reports on two methods of classifying the spectral data from an optical fibre based sensor system as used in the food industry. The first method uses a feed-forward back-propagation Artificial Neural Network while the second method involves using Kohonen Self-Organising Maps. The sensor monitors the food colour online as the food cooks by examining the reflected light, in the visible region, from both the surface and the core of the product The combination of using Principal Component Analysis (PCA) and backpropagation neural networks has been successfully investigated previously. In this paper, results obtained using this method are compared with results obtained using a Self-Organising Map trained on the Principal Components. PCA is performed on the reflected spectra, which form a "colourscale" - a scale developed to allow the quality of several products of similar colour to be monitored i.e. a single classifier is trained, using the colourscale data that can classify several food products. The results presented show that both classifiers perform well.

Research Summary: Oregon's Measure 11, a mandatory minimum sentencing policy passed in 1994, had fewer negative system impacts than had been anticipated by many state and local criminal justice administrators, due largely to the fact that prosecutors exercised the discretion provided them under the law to selectively prosecute cases. Consequently, fewer Measure 11-eligible cases were sentenced under the relevant statues than before passage of the measure, and more were sentenced to lesser related offenses. At the same time, incarceration rates and sentence lengths increased for both Measure 11 and lesser related offenses. Trial rates increased for two years after Measure 11 took effect before reverting to previous levels. Policy Implications: The “unintended consequences” that Measure 11 produced should not have been unexpected. Our research indicates that the entire system will quickly adapt to mitigate the more draconian outcomes predicted by those who assume a simplistic implementation, which underscores the importance of understanding system dynamics and inter-relationships before implementing reform, as well as the pitfalls of designing legislation for either symbolic appeal or formal logic rather than for actual effect.

The objectives of Human Engineering (HE) are generally viewed as increasing human performance, reducing human error, enhancing personnel and equipment safety, and reducing training and related personnel costs. There are other benefits that are thoroughly consistent with the direction of the Navy of the future, chief among these is reduction of required numbers of personnel to operate and maintain Navy ships. The Naval Research Advisory Committee (NRAC) report on Man-Machine Technology in the Navy estimated that one of the benefits from increased application of man-machine technology to Navy ship design is personnel reduction as well as improving system availability, effectiveness, and safety The objective of this paper is to discuss aspects of the human engineering design of ships and systems that affect manning requirements, and impact human-performance and safety The paper will also discuss how the application of human engineering leads to improved performance, and crew safety, and reduced workload, all of which influence manning levels. Finally, the paper presents a discussion of tools and case studies of good human engineering design practices which reduce manning.

International Conference on application Specific Array Processors

作者： R. Lang A. Spray Application Specific Computer Design Department of Electrical and Computer Engineering University of Newcastle Australia Application Specific Computer Design Department of Electrical and Computer Engineering University of Newcastle Australia

The Discrete Wavelet Transform (DWT) is a signal processing technique popularised by its results in data compression. Considerable work has been done in designing novel architectures to perform the DWT, including a systolic architecture designed by the authors, but little attention has been given to the inverse DWT which is needed in applications such as data compression for signal reconstruction. Despite the fact that the inverse DWT is computationally the reverse of the DWT, the hardware design for the architecture is not simply mirrored. Existing designs expect the architecture for the inverse DWT to be a simple follow-on step from the DWT design, however this is not the case. We present one such problem here, showing the FIFO buffering required on the input of the inverse architecture. We show how the size of this buffer can be calculated and compare it to a fixed data array implementation. This work is based on our systolic array design and is an integral part of the inverse DWT design we are working on for image and video compression.

This paper explores the solutions offered by switched capacitor (SC) techniques for the implementation of fuzzy circuits. The architecture of a microcontroller is presented to perform the simplified inference method and the circuit realizations of the different blocks are described. The design technique achieves high operation speed, typical in analog operation, and at the same time allows the programming ease which is characteristic of digital implementations. Finally, due to the defuzzifier used, the proposed microcontroller may interact with either an analog or digital system at the output.< >

This paper investigates the multiconductor busbar behaviour under AC conditions with the aim of comparing the predictions of traditional circuit models with a more accurate analysis based on the electromagnetic field computation. This analysis employs a two‐dimensional finite‐element technique including eddy‐current effects. In linear systems this approach leads to a circuit model described by an impedance matrix, while, in presence of saturable media, field and circuit equations are simultaneously solved by a voltage‐driven field formulation. The paper analyses the behaviour of two different busbar systems when a short‐circuit current flows through them;the results obtained by the proposed approach are compared with those deduced according to the methods suggested by the IEC Standards and by the symmetrical components.
