This paper describes a multiple-view meta-modeling approach for managing variability in software product lines using the Unified Modeling Language notation (UML). A multiple-view meta-model for software product lines describes how each view relates semantically to other views. The metamodel depicts life cycle phases, views within each phase, and meta-classes within each view. The relationships between the meta-classes in the different views are described. Consistency checking rules are defined based on the relationships among the meta-classes in the meta-model. This paper briefly describes multiple-view modeling of software product lines before describing the multiple-view meta-modeling approach for software product lines and an approach for consistency checking between meta-model views. The paper then provides a detailed description of the tool support for product line multipleview meta-modeling, meta-model consistency checking, and product line member configuration from the product line architecture. © Springer-Verlag Berlin Heidelberg 2004.

THEMIS (Threat Evaluation Metamodel for information systems) is a description logic-based framework to apply state, federal, and international law to reason about the intent of computer network attacks with respect to collateral consequences. It can be used by law enforcement agencies and prosecutors to build legally credible arguments, and by network designers to keep their defensive and retaliatory measures within lawful limits. THEMIS automates known quantitative measures of characterizing attacks, weighs their potential impact, and places them in appropriate legal compartments. From the perspective of computer networks, we develop representations and a way to reason about the non-network related consequences of complex attacks from their atomic counterparts. From the perspective of law, we propose the development of interoperable ontologies and rules that represent concepts and restrictions of heterogeneous legal domains. The two perspectives are woven together in THEMIS using description logic to reason about and guide defensive, offensive, and prosecutorial actions. © Springer-Verlag Berlin Heidelberg 2004.

Concurrent accesses to a file frequently occur in a distributed computing environment where a few number of network-attached servers are designated as a data storage pool and the clients are physically connected to the servers via network, like GigaEthernet or Fibre Channel. In such a distributed computing environment, one of the major issues affecting in achieving substantial I/O performance and scalability is to build an efficient locking protocol. We present a distributed locking protocol that enables multiple client nodes to simultaneously write their data to distinct data portions of a file, while providing the consistent view of client cached data, and conclude with an evaluation of the performance of our locking protocol on a Linux cluster. © Springer-Verlag 2004.

This paper makes two contributions to the study of configuring real-time aspects into quality of service (QoS)-enabled component middleware for distributed real-time and embedded (DRE) systems. First, it compares and contrasts the integration of real-time aspects into DRE systems using conventional QoS-enabled distributed object computing (DOC) middleware versus QoS-enabled component middleware. Second, it presents experiments that evaluate real-time aspects configuredin The ACE ORB (TAO) versus in the Component-Integrated ACE ORB (CIAO). Our results show that QoS-enabled componentmiddleware can offer real-time performance that is comparable to DOCmiddleware, while giving greater flexibility to compose and configure key DRE system aspects. © Springer-Verlag Berlin Heidelberg 2004.

Over the last four years, a community of researchers working on Grid and High Performance Computing technologies started discussing the barriers and opportunities that grid technologies must face and exploit for the development of health-related applications. This interest lead to the first Healthgrid conference, held in Lyon, France, on January 16th–17th, 2003, with the focus of creating increased awareness about the possibilities and advantages linked to the deployment of grid technologies in health, ultimately targeting the creation of a European/international grid infrastructure for health. The topics of this conference converged with the position of the eHealth division of the European Commission, whose mandate from the Lisbon Meeting was "To develop an intelligent environment that enables ubiquitous management of citizens’ health status, and to assist health professionals in coping with some major challenges, risk management and the integration into clinical practice of advances in health knowledge." In this context "Health" involves not only clinical procedures but covers the whole range of information from molecular level (genetic and proteomic information) over cells and tissues, to the individual and finally the population level (social healthcare). Grid technology offers the opportunity to create a common working backbone for all different members of this large "health family" and will hopefully lead to an increased awareness and interoperability among disciplines. The first HealthGrid conference led to the creation of the Healthgrid association, a non-profit research association legally incorporated in France but formed from the broad community of European researchers and institutions sharing expertise in health grids. After the second Healthgrid conference, held in Clermont-Ferrand on January 29th–30th, 2004, the need for a "white paper" on the current status and prospective of health grids was raised. Over fifty experts from different areas of grid tec

IEEE Asia-Pacific Conference on Circuits and systems

This work proposes a reconfigurable adaptive FEC system. For adaptive FEC schemes, we can implement an FEC decoder which is optimal for error correction capability (t) by taking the number of operations into consideration. Reconfiguring the optimal FEC decoder dynamically for each t allows us to maximize the throughput of each decoder within a limited hardware resource. Our system can reduce packet dropping rate more efficiently than conventional fixed hardware systems for a reliable transport protocol.

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.

The KL-Miner procedure for datamining

The KL-Miner procedure for datamining

作者： Lín, Václav Dolejší, Petr Rauch, Jan Simůnek, Milan Dept. of Information Engineering EuroMISE Centrum - Cardio Laboratory for Intelligent Systems University of Economics Prague nam. W. Churchilla 4 130 67 Praha 3 Czech Republic Institute of Computer Science Acad. of Sci. of the Czech Republic Pod Vodarenskou vezi 2 182 07 Prague 8 Czech Republic

KL-Miner [9] is a datamining procedure that, given input data matrix M and a set of parameters, generates patterns of the form R ∼ C/7- Here R and C/γ are categorial attributes corresponding to the columns of M, and 7 is a Boolean condition defined in terms of the remaining colums of M. The pattern R ∼ C/γ means that R and C are strongly correlated on the submatrix of M formed by all the rows of M that satisfy γ. What is meant by "strong correlation" and how are R, C and γ generated is determined by the input parameters of the procedure. KL-Miner conforms to the GUHA principle formulated in [1], It revives two older GUHA procedures described in [2]: it is very much related to CORREL and contains a new implementation of COLLAPS as a module. In this paper, we mention the motivation that leads to designing of KL-Miner, describing our new implementation of COLLAPS and giving application examples that illustrate the main features of KL-Miner.

RoboCup has been known for the goal of “creating robots capable of beating the world cup in 2050.” Clearly, we stated this goal back in 1996 not as an exact scientific goal, but as an audacious challenge to pursue. We aimed at creating a far away target for RoboCup researchers, as we were well aware that the development of fully autonomous soccer robots capable of competing against human world champion soccer players was a rather long term research project.
