In this paper a novel approach is presented for generating RDF graphs of arbitrary complexity from various spreadsheet layouts. Currently, none of the available spreadsheet-to-RDF wrappers supports cross tables and tables where data is not aligned in rows. Similar to RDF123, XLWrap is based on template graphs where fragments of triples can be mapped to specific cells of a spreadsheet. Additiona...

Guaranteed Annuity Options (GAOs) are options available to holders of certain pension policies. Under these contracts, policyholders contribute premiums into a fund managed by the insurer. At retirement, the policyholders buy life annuities at a guaranteed rate provided by the original insurer, or annuitize with another insurer. If the guaranteed annuity rates are better than the prevailing rat...

This paper presents the determination of power transfer between two buses that takes into account the dynamic security constraint. The dynamic security constraint based transient stability has been found to be one of the limiting factors in determining the power transfer so-called as the available transfer capability (ATC). The multimachine integral square generator angle (ISGA) index is used t...

This paper presents a novel strategy for the detection and tracking of objects in low resolution video sequences. The processing is performed in run-time, considering only few buffered frames. Our approach consists of three main steps: (i) spatial segmentation by means of clustering, (ii) candidate set reduction based on feature extraction (iii) choice of the best candidates. The searching regi...

We study the problem of clustering uncertain objects whose locations are uncertain and described by probability density functions. We analyze existing pruning algorithms and experimentally show that there exists a new bottleneck in the performance due to the overhead while pruning candidate clusters for assignment of each uncertain object in each iteration. We further show that by considering s...

a r t i c l e i n f o Keywords: Bicycle share Transportation justice Low-cost mobility Public bicycle systems This paper seeks to examine the degree to which a public bicycle system could meet the needs of people in Cape Town, South Africa, a middle-income city with significant resource constraints and transport justice considerations. The local authority in Cape Town has an explicit policy to ...

As humans increasingly acknowledge the effects that they are having on the planet, there is a realisation implicit in these effects that human interrelationships with nature are actually arbitrated and expedited exploitatively. Understanding how the different discourses and histories through which the interrelationships with nature are mediated and actually told and then retold is fundamental t...

Basketter and Safford discuss estimating acceptable exposure levels based on data from human testing or from the Local Lymph Node Assay (LLNA), which is clearly the test that should be conducted for new chemicals or chemical registrations. However, LLNA data are not available for many existing chemicals which may nonetheless need to be evaluated under time and budgetary circumstances where new ...
