Modern enterprises are irreversibly dependent on large-scale, adaptive, component-based information systems whose complexity frequently exceeds current engineering capabilities for intellectual control, resulting in persistent difficulties in system development, management, and evolution. We propose an innovative framework of engineering representation and reasoning methods for developing these complex systems: the flow-service-quality (FSQ) framework. In dynamic network information systems with constantly varying function and usage, workflows and their corresponding traces of system services act as stable foundations for functional and non functional (quality attribute) specification, design, and operational control. Our objective is to provide theoretical foundations, language representations, and rigorous yet practical unified engineering methods to represent and reason about system flows as essential artifacts of system specification, design, and operation. © 2002 IEEE.

We investigate the use of perceptrons for classification of microarray data. Small round blue cell tumours of childhood are difficult to classify both clinically and via routine histology. Khan et al. [10] showed that a system of artificial neural networks can utilize gene expression measurements from microarrays and classify these tumours into four different categories. We used a simulated annealing-based method in learning a system of perceptrons, each obtained by resampling of the training set. Our results are comparable to those of Khan et al., indicating that there is a role for perceptrons in the classification of tumours based on gene expression data. We also show that it is critical to perform feature selection in this type of models. © Springer-Verlag Berlin Heidelberg 2002. © Springer-Verlag Berlin Heidelberg 2002.

Proceedings of the conference on Application and theory of petri nets: formal methods in software engineering and defence systems - Volume 12

This paper presents a project where Hierarchical Coloured Petri Nets have been used to formally specify and analyse an operational planning process in a deployable Headquarters of the Australian Defence Force. A CPN model has been constructed for capturing the planning process, qualitative metrics have been defined for analysis of the planning process, and the CPN model has been analysed using state space analysis methods. The paper focusses on a concrete representative planning process as observed in a training exercise. The modelling approach, defined metrics, and state space analysis techniques are applicable also in other application domains for process modelling.

Embeddable microinstruments for corrosion monitoring

Corrosion 1997

作者： Kelly, R.G. Yuan, J. Jones, S.H. Blanke, W. Aylor, J.H. Wang, W. Batson, A.P. Wintenberg, A. Clemefla, G.G. Departments of Materials Science and Engineering Electrical Engineering Computer Science School of Engineering and Applied Science University of Virginia CharlottesvilleVA22903 United States Instrumentation and Control Division Oak Ridge National Laboratory Oak RidgeTN37831-6006 United States Virginia Transportation Research Council CharlottesvilleVA22903 United States

The design and development of an embeddable corrosion measurement microsystem which takes advantage of the increased availability of Application Specific Integrated Circuit (ASIC) development and Very Large Scale Integrated (VLSI) circuit manufacturing is described. Key elements of the system (micropotentiostat with zero resistance ammeter (ZRA) and analog-to-digital (A/D) and digital-to-analog (D/A) converters were tested electronically and found to perform satisfactorily. The micropotentiostat/ZRA combination was also tested on steel electrodes exposed to 0.6 M NaCl, saturated Ca(OH)2, and saturated Ca(OH)2 + 0.6 M NaCl. Comparisons of polarization resistance data generated by the micropotentiostat and commercially available systems demonstrated that the two systems performed equivalently. The 10-bit A/D and 6-bit D/A converters exhibited excellent linearity over a wide range of inputs. Future directions for the development of the embeddable corrosion measurement microsystem are also outlined. © 1997 by NACE International.

Hybrid simulation includes both functional computer software models and actual hardware subsystems operating as an integrated whole. A ''hot test bed'' or a ''hybrid simulator-emulator'' enables design engineers to evaluate conceptual models in a more realistic real-lime context, but places increased cognitive demands on the designer. This paper describes an architecture, and results from a prototype implementation, for a design decision support system to allow a designer to make more productive and cost effective use of a test bed system.

Expert Knowledge-Based Traction control of a Truck Using Fuzzy Logic

引用

IFAC Proceedings Volumes 1996年第1期29卷 7867-7872页

作者： Ka C. Cheok Kazuyuki Kobayashi Francis B. Hoogterp Dept. Of Electrical and Systems Engineering School of Engineering and Computer Science Oakland University Rochester MI 48309-4401 Division of Track and Running Gear US Army Tank-automotive and Armament Command (TACOM) Warren MI 48397-5000

This paper describes a fuzzy logic (FL) approach for incorporating an expert knowledge-based Traction control System (TCS) for a four-wheel drive vehicle. The knowledge base is provided by a survey of existing TCS methods, understanding of the TCS hardware components and tyre adhesion characteristics, evaluation of applicable control methods, computer simulation studies, and feedback information from experienced traction test drivers in the automotive industry. The developed FL-bascd TCS was implemented on a Pentium PC system- level traction controller computer installed on a 4x4 pickup truck. Extensive experiments for traction control was conducted at available test facilities and proving grounds. The system-level fuzzy logic approach readily permits modification of old and incorporation of new ideas. The success of this fuzzy logic-based design approach was demonstrated to the government sponsor and industrial partners.
