This paper presents the main concepts of the IST Project FAIN "Future Active IP Networks" [10], a three-year collaborative research project, whose main task is to develop and validate an open, flexible, programmable and dependable network architecture based on a novel active node approach. This generic architecture for active networks is an innovative integration of active networking, distributed object and mobile agent technology. Starting from the definition of a business model that underlines the FAIN architecture, we identify three key working areas for contribution: the active node platform layer, the service programming environment and a built-in management system. The active node platform layer of the FAIN Active Node is comprised of the kernel Operating System, a node resource access control framework, and active components for management, security and service pro-H. vision. These elements provide the foundations for Execution Environments so that they can operate in an independent manner. A novel service programming environment is envisaged to enable the dynamic creation or update and to secure deployment and operation of protocols. Such an environment supports various role-specific ways of deployment, e.g. application-specific signalling or operator-governed network control signalling. © Springer-Verlag Berlin Heidelberg 2000.

The BL Lac object Mrk 501 came into a high flaring state in 1997, brightest in the sky at TeV energies. Using the air shower data obtained with a high density part of the Tibet II array, being operating at Yangbajing since 1996, we searched for γ-ray signals from this source during the period from February to August in 1997. The result shows a 3.7σ excess for showers with its mode energy 3 TeV for the whole period and 4.7σ excess for the period from April 7 to June 16. The estimated energy spectrum of γ rays is consistent with those obtained by imaging atmospheric Cherenkov detectors.

CANGAROO group constructed an imaging air Cherenkov telescope (CANGAROO-II) in March 1999 at Woomera, South Australia to observe celestial gamma-rays in hundreds GeV region. It has a 7m parabolic mirror consisting of 60 small plastic spherical mirrors, and the prime focus is equipped with a multi-pixel camera of 512 PMTs covering the field of view of 3 degrees. We report initial performance of the telescope.

One of the important problems for 3-layered neural networks (3-LNN) is to determine the optimal network structure with high generalization ability. Although this can be formulated in terms of a statistical model selection, there remains a problem in applying traditional criteria for 3-LNN. We suggest the type of effective criteria for the model selection problem of 3-LNN by analyzing the statistical properties of some simplified nonlinear models. Results of numerical experiments are also presented. © 1999 IEEE.

We apply evolutionary computations to the Hopfield's neural network model of associative memory. In the model, some of the appropriate configurations of synaptic weights giv e the network a function of associative memory. One of our goals is to obtain the distribution of these configurations in the synaptic weight space. In other words, our aim is to learn a geometry of a fitness landscape defined on the space. For the purpose, we use evolutionary walks to explore the fitness landscape in this paper. © Springer-Verlag Berlin Heidelberg 1998.

Personal mobility – a fundamental characteristic of Nomadic Computing – creates an environment in which a user roams without a wireless laptop or a mobile phone and yet enjoys anytime, anywhere network accessibility. This paper gives an overview of Nomad's Personal Access System (NPAS), OSI application layer software that provides a personal mobility environment within a virtual network. In addition, it focuses on the part of NPAS, called Site Profile Agent. Site Profile Agent is an inter-site negotiating agent that communicates with its peer to decide services for a nomad. This work is motivated by the larger project of the Mobile Agents Alliance, a collaboration that includes the National Research Council of Canada, the University of Ottawa, and Mitel Corp. © Springer-Verlag Berlin Heidelberg 1998.

We apply evolutionary computations to Hopfield model of associative memory. Although there have been a lot of researches which apply evolutionary techniques to layered neural networks, their applications to Hopfield neural networks remain few so far. Previously we reported that a genetic Mgorithm using discrete encoding chromosomes evolves the Hehb-rule associative memory to enhance its storage capacity. We also reported that the genetic algorithm evolves a network with random synaptic weights eventually to store some number of patterns as fixed points. In this paper we present an evolution of the Hopfield model of associative memory using evolutionary programming as a reM-valued parameter optimization. © Springer-Verlag Berlin Heidelberg 1997.
