Temporal association rule mining promises the ability to discover time-dependent correlations or patterns between events in large volumes of data. To date, most temporal data mining research has focused on events existing at a point in time rather than over a temporal interval. In comparison to static rules, mining with respect to time points provides semantically richer rules. However, accommo...

Designing a data archive and data access capability is an important development area for realizing satellite experiment objectives. The data center must be designed to provide a consistent and stable environment yet at the same time be able to adapt to the inevitable technological changes. This paper discusses such a framework being developed for an Air Force experimental satellite.

In a research project funded by the German Research Foundation, meteorologists, data publication experts, and computer scientists optimised the publication process of meteorological data and developed software that supports metadata review. The project group placed particular emphasis on scientific and technical quality assurance of primary data and metadata. At the end, the software automatica...

This article presents the design of the network infrastructure of a Data Center that meets the requirements arising from Cloud Computing, for use in the Health Sector of Arequipa city, focusing on network layer 2 and its dimensionality to meet the requirements of several health service applications. The network infrastructure dimensionality calculation is a complex challenge for an of the groun...

Data management plans, data sharing plans and the like are now required by funders worldwide as part of research proposals. Concerned with promoting the notion of open scientific data, funders view such plans as the framework for satisfying the generally accepted requirements for data generated in funded research projects, among them that it be accessible, usable, standardized to the degree pos...

In this paper we study the correlation structure of the output process of an ATM multiplexer. We consider two special cases : (i) the output process of the D-BMAP/D/1/N queue, a generic model for an ATM multiplexer and (ii) a process which results from a renewal process which shares the output link of a multiplexer with other connections. Both output processes belong to the versatile class of d...

The effects of networks on the performances of cloud architectures are a very significant issue in designing a data center. The efficiency of data transfers and the overall traffic management are a critical factor that constitutes a potential performance bottleneck, potentially limiting the number of computing nodes that can be installed more than their cost issues. In this paper we present a m...

The growing importance of information technologies (IT) could be the hallmark of our era, with its transformational effect in “changing the world” (Agarwal and Lucas, 2005, p. 391). The amount spent on IT, around $2.6 trillion in 2006, a 5% increase from 2005 (Gartner Group, cited in Edwards, 2004) is a good indication of its worldwide dissemination. Spending in this area is led by the U.S. and...

The World Data Centre for Geomagnetism, Mumbai is functioning as a division of Indian Institute of Geomagnetism, Navi Mumbai since its full fledges activities commenced in 1991 in coordination with International Council of Scientific Union (ICSU) Panel on World Data Centres. The responsibility of the compilation of final hourly absolute values of nine of the Indian magnetic observatories and de...
