A description of a data item’s provenance can be provided in different forms, and which form is best depends on the intended use of that description. Because of this, different communities have made quite distinct underlying assumptions in their models for electronically representing provenance. Approaches deriving from the library and archiving communities emphasise agreed vocabulary by which ...

This paper reviews the Ogre classification of Big Data application with 50 facets divided into four groups or views. These four correspond to Problem Architecture, Execution mode, Data source and style, and the Processing model used. We then look at multiple existing or proposed benchmark suites and analyze their coverage of the different facets suggesting a process to obtain a complete set. We...

The method of recurrence plots is extended to the cross recurrence plots (CRP), which among others enables the study of synchronization or time differences in two time series. This is emphasized in a distorted main diagonal in the cross recurrence plot, the line of synchronization (LOS). A non-parametrical fit of this LOS can be used to rescale the time axis of the two data series (whereby one ...

Public bike renting is more and more popular in cities to incentivise a reduction in car journeys and to boost the use of green transportation alternatives. One of the challenges of this application is to effectively plan the resources usage. This paper presents some analysis of Dublin bike renting scheme based on statistics and data mining. It provides available bike patterns at the most inter...

The paper aims to examine the determinants of profit performance of financial holding companies (FHCs) using panel data for the period 2001–9. The effects of bankspecific ownership structure and dualcore strategy are examined. Our findings show that (1) business diversification, a lower financial cost, a higher liquidity ratio, larger assets, and lower debt ratios can improve the profit perform...

Metadata production for research datasets is not a trivial problem. Standardized descriptors are convenient for interoperability, but each area requires specific descriptors in order to guarantee metadata comprehensiveness and accuracy. In this paper, we report on an ongoing research data management experience at the University of Porto (U. Porto), which led to the proposal of a domain-specific...

OBJECTIVES Our objective is to integrate high performance computing (HPC) technologies and bioacoustics data-mining capabilities by offering a MATLAB-based toolbox called Raven-X. Raven-X will provide a hardware-independent solution, for processing large acoustic datasets the toolkit will be available to the community at no cost. This goal will be achieved by leveraging prior work done by Dugan...

The recently-discovered, nearby young supernova remnant in the southeast corner of the older Vela supernova remnant may have been seen in measurements of nitrate abundances in Antarctic ice cores. Such an interpretation of this twenty-year-old ice-core data would provide a more accurate dating of this supernova than is possible purely using astrophysical techniques. It permits an inference of t...

Virtualization has rapidly become a go-to technology for increasing efficiency in the data center. With virtualization technologies providing tremendous flexibility, even disparate architectures may be deployed on a single machine without interference. Awareness of limitations and requirements of physical hosts to be used for virtualization is important. This paper reviews the present virtualiz...

The Performing Arts Data Service (PADS), funded by the Joint Information Systems Committee (JISC) and based at the University of Glasgow, aims to support research and teaching in UK Higher Education by collecting and promoting the use of digital data relating to the performing arts: music, film, broadcast arts, theatre and dance. The PADS is one of 5 service providers of the Arts and Humanities...
