  • An Event -Triggered Time Synchronization Scheme for Sensor Networks

    Publication Year: 2008, Page(s):3 - 7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (562 KB) | HTML iconHTML

    Distributed time synchronization is an important part of sensor networks. Due to the limited battery capacity of the sensor nodes, applicable schemes should concern the energy consumption of the networks. To achieve better efficiency, an event-triggered time synchronization scheme (ETTS) is presented, which aims at providing on-demand time synchronization in sensor networks. The scheme is composed...

    Accurate assessment of mobility in bed presents challenges to clinicians and researchers alike. It is traditionally performed by either overnight polysomnograph recording or wrist-actigraphy. A different approach is instrumenting the bed itself rather than the sleeping subject. This paper describes an alternative system for unobtrusive monitoring of mobility in bed that uses load sensors installed... View full abstract»

    Research efforts in pervasive healthcare have mainly focused on software infrastructures for capture and access, multimodal interaction and manipulation of context information. In this paper we discuss the importance and the use of mechanisms for the extension of information captured from pervasive healthcare environments. Based on our findings from a field study of medical grand rounds, we develo... View full abstract»

    Telemedicine means administering medicine over the mobile Internet. This may involve mobile clinics (MC) which, while moving from one geographical location to another to treat patients, always maintain contact with the distant medical centre for backup in the patient treatment process. Usually patients in different geographical locations would have varied illnesses and health profiles. These diffe... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (573 KB) | HTML iconHTML

    Public Transportation systems have been developed and formed independently from one another although they are within the same regional province. There are little coordination and collaboration between public transport operators and little integration and interoperability among their Fare Collection systems. This report presents the research and findings of barriers to Integrated Smart Card Fare Co... View full abstract»

  • Formal Modeling and Analysis of a Distributed Database Protocol in Maude

    Publication Year: 2008, Page(s):37 - 44
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (506 KB) | HTML iconHTML

    This paper illustrates how the rewriting-logic-based Maude tool, and its extension real-time Maude, can be applied to the formal object-oriented specification, simulation, and model checking of the two-phase commit protocol for distributed databases. Maude's intuitive yet expressive specification language, its support for object-oriented formal specification, its high-performance formal analysis f... View full abstract»

    Incremental maintenance of association rules is an interesting problem that has been tackled in several research works. Even though literature abundance in this way, there is still a lack of methods that process the complete maintenance problem, that is, incremental maintenance for any type of update (insertion or deletion of data) and for any new support threshold. In this paper, we develop a new... View full abstract»

  • Combining Parallel Self-Organizing Maps and K-Means to Cluster Distributed Data

    Publication Year: 2008, Page(s):53 - 58
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (645 KB) | HTML iconHTML

    Clustering is the process of discovering groups within multidimensional data, based on similarities, with a minimal knowledge of their structure. In previous works, we presented an algorithm (partSOM) to cluster distributed datasets, based on self-organizing maps (SOM). This work extends this approach presenting a strategy for efficient cluster analysis in distributed databases using SOM and K-mea... View full abstract»

    This study is an initial attempt to improve the understanding of relationships between land use patterns and travel behavior. By using exploratory multivariate data analysis (EMDA), this work investigates the factors that influence the destination choices (travel distances sequences) during the trip-chaining of the residents in the Sao Paulo Metropolitan Area (SPMA). It is an exploratory analysis ... View full abstract»

    Traditional mechanical design process faces three major challenges: (1) the need for rapid and repeated numerous time-consuming simulations, such as finite element analysis and computational fluid dynamics; (2) the need for dataset management; (3) the lack of an integrated and easy-to-use collaborative mechanical design environment. This paper presents a grid-enabled solution for mechanical engine... View full abstract»

    Grids are emerging as a promising solution for resource and computation demanding applications. Here, task scheduling is one of the most important subjects. In traditional approaches for grid scheduling, makespan or completion time of scheduling is the most important parameter for optimization. But in these algorithms, some parameters like user requirements arenpsilat considered. Over the last few... View full abstract»

    In data-oriented services in grids applications process data from multiple data sources among multiple administrative domains. Integration of heterogeneous data sources provides a unified data access with a unified virtual organization security mechanism. We propose design of a virtual organization file system (VOFS) which aggregates different heterogeneous file systems to provide data sharing bet... View full abstract»

    This paper presents an approach to predict userpsilas interests in Web-based educational systems, using the collaborative filtering methods weighted by implicit information about userpsilas navigation. To test and evaluate the proposed approach, we used a particular case study. The values were obtained by a domain specialist and we compared the approach results using a cross-validation method.
