IEEE International Workshop on Factory Communication systems (WFCS)

作者： S. Giannoulis C. Katsanos S. Koubias G. Papadopoulos Dept. of Electrical Engineering & Computer Technology Patras Greece Industrial Systems Institute Patras Greece

Ad hoc networks are characterized by dynamic topology caused by node mobility, multihop wireless connectivity and channel non-deterministic behavior (interference, multipath, hidden and exposed node problem make the wireless channel very difficult to predict). The behavior of ad hoc networks must be analyzed in detail as a result of the pairing of the selected MAC and routing protocols. We focus our studies in the routing layer while closely observing the developments in MAC layer. We present and examine the characteristics of a new hybrid adaptive routing protocol based on the ZRP protocol.

Learning algorithms generally rely on contemporary neural architectures having one or more hidden layers and they suffer from the same deficiencies that genetic algorithms and methodologies for non-trivial automatic programming do, namely, they cannot exploit inherent domain symmetries for the transference of knowledge from an application of lesser to greater rank, or across similar applications. As a direct consequence, no ensemble of contemporary neural architectures allows for the effective codification and transference of knowledge within a society of individuals (i.e., swarm knowledge). These deficiencies stem from the fact that contemporary neural architectures cannot reason symbolically using heuristic ontologies. They cannot, directly provide symbolic explanations of what was learned for purposes of inspection and verification. Moreover, they do not allow the knowledge engineer to precondition the internal feature space through the application of domain-specific modeling languages. A symbolic representation can support the heuristic evolution of an ensemble of neural architectures. Each neural network in the ensemble imbues a hidden layer and for this reason is NP-hard in its learning performance. It may be argued that the internal use of a neat representation subsumes the heuristic evolution of a scruffy one. It follows that there is a duality of representation under transformation. The goal of AI then is to find symbolic representations, transformations, and associated heuristic ontologies. This paper provides an introduction to this quest. © 2004. 13th International Conference on Intelligent and Adaptive systems and Software engineering 2004, IASSE 2004. All rights reserved.

This paper reviews what the first Author and his Group have been investigating for the past decade in the on-line steady-state hierarchical intelligent control and optimization of large-scale industrial processes (LSIP), as well as large-scale systems (LSS). The techniques include the use of neural networks for identification and optimization, the use of expert systems to solve some kinds of hierarchical multi-objective optimization problems, the use of the fuzzy logic control and the use of the iterative learning control. In addition, several implementation examples and the product quality control for LSS are introduced. Finally the paper prospects the new stages of development. © 2004 IFAC.

Recently, there has been much progress in wearable computing. Input/output interface and security are important research areas in wearable computing. In this paper, we describe considerations which should be taken into account in designing a wearable interface and iris recognition system. One of the most important issues in designing a wearable iris recognition system is the radial lens distortion. We suggest a radial distortion elimination method which is simple but accurate. Experimental results show that the quality of the image captured by our system is good enough for iris recognition and we can achieve 0.18% of the EER by applying our proposed radial distortion elimination method. © Springer-Verlag Berlin Heidelberg 2004.

Control methods to enhance large-scale inverter output voltages

Quarterly Report of RTRI (Railway Technical Research Institute) (Japan) 2004年第1期45卷 17-20页

The superconducting magnetic levitation (maglev) system under development in Japan uses a linear synchronous motor (LSM) with armature coils on the ground. The power converter driving the LSM should be able to generate power of variable voltage and frequency according to the speed and thrust of the train. Therefore, we adopted a pulse width modulation (PWM) inverter on the Yamanashi Maglev Test .Line. For power conversion the maglev system requires highly efficient large-scale PWM inverters. In addition, manufacturing costs had to be reduced, so we developed several control methods to enhance the output voltages of the inverter without changing its circuit configuration. This paper describes the characteristics and some results from experiments involving these control methods.

For the first time, we demonstrate 3D integration of self-aligned IrO 2(Hf)/LaAlO3/GOI CMOSFETs above 0.18 μm Si CMOSFETs. At EOT=1.4nm, the novel IrO2(Hf) dual gates (4.4 and 5.1 eV workfunction) on control 2D LaAlO3/Si devices have high electron and hole mobilities of 203 and 67 cm2/Vs. On the 3D structure the LaAlO3/ GOI shows even higher 389 and 234 cm2/Vs mobilities, and process compatibility with current Si VLSI. The higher drive current, larger integration density, shorter interconnects distance, and simple process of 3D approach can help solve the AC power issue and 2D scaling limitation. ©2004 IEEE.

The transport of quantum dots (QDs) in a silicon-on-insulator (SOI) nano-wire transistors at lower temperature was investigated. The transistor was fabricated on a boron-doped separation-by-implanted oxygen SOI wafer. SOI film was patterned by electron beam and reactive ion etching to define a narrow channel. The independent branching of Coulomb oscillations and overlapping Coulomb diamonds suggested that there were two parallel active QDs. The transport at low temperature showed typical characteristics of two parallel QDs. The spectrum of dID/dVDS of the QDs evidenced the tunneling through the tunnel junction between the two QDS.

Asian Control Conference

作者： S.R. Munasinghe Ju-Jang Lee T. Usui M. Nakamura N.

Effective training is essential for human teleoperators to deliver satisfactory performance in actual tasks. Teleoperation is naturally a very difficult task due to the absence of naked-eye vision that cripples the cognitive behavior of the remote operator. Camera vision somehow is not a satisfactory substitution. However, training with naked-eye vision feedback may help human teleoperators to learn how to deliver satisfactory performance when they actually interact with camera vision. This study was carried out to further investigate this hypothesis, and to quantitatively supplement it with experimental proofs. For this cause, the recently built telerobotic test-bed between KAIST (Korea) and Saga University(Japan) was reshaped to a telerobotic mini-golf system, which is the trial experiment in this study. The performance of the players with and without naked-eye training was compared and quantitatively evaluated. The effectiveness of training with naked-eye vision was verified as an essential part in training human teleoperators.

International Symposium on Communications and Information Technologies (ISCIT)

Fukui Dept. of Information Systems Tottori University of Environmental Studies Tottori Japan Dept. of Electronics and Computer Engineering Tsuyama National College of Technology Tsuyama-shi Okayarna Japan Dept. of Electrical and Electronic Engineering Tottori University Tottori Japan

In this paper, we propose a new method for active net model. The active net is a lattice network model that is based on minimizing energy to extract the region of a target object. In a conventional method, only one target is detected by one net. Therefore, assuming that the image can be divided into some parts, the proposed method uses many nets and applies them to each divided image. Some simulation results are presented obtained by applying the proposed method to images. In the proposed method, since the size of a net becomes small, the processing time to one net can be shortened. Furthermore, since the distance between lattice points is short in the initial net, the target at the end of an image becomes detectable. That is, it means that the target detection performance has improved.
