Found in: 2013 IEEE World Congress on Services (SERVICES)
By Artem Chebotko,John Abraham,Pearl Brazier,Anthony Piazza,Andrey Kashlev,Shiyong Lu
Issue Date:June 2013
pp. 1-8
Provenance, which records the history of an in-silico experiment, has been identified as an important requirement for scientific workflows to support scientific discovery reproducibility, result interpretation, and problem diagnosis. Large provenance datas...
 
Distributed Semantic Web Data Management in HBase and MySQL Cluster
Found in: Cloud Computing, IEEE International Conference on
By Craig Franke,Samuel Morin,Artem Chebotko,John Abraham,Pearl Brazier
Issue Date:July 2011
pp. 105-112
Various computing and data resources on the Web are being enhanced with machine-interpretable semantic descriptions to facilitate better search, discovery and integration. This interconnected metadata constitutes the Semantic Web, whose volume can potentia...
 
Distributed Storage and Querying Techniques for a Semantic Web of Scientific Workflow Provenance
Found in: Services Computing, IEEE International Conference on
By John Abraham, Pearl Brazier, Artem Chebotko, Jaime Navarro, Anthony Piazza
Issue Date:July 2010
pp. 178-185
In scientific workflow environments, scientific discovery reproducibility, result interpretation, and problem diagnosis primarily depend on provenance, which records the history of an in-silico experiment. Resource Description Framework is frequently used ...
 
Efficient Processing of Semantic Web Queries in HBase and MySQL Cluster
Found in: IT Professional
By Craig Franke,Samuel Morin,Artem Chebotko,John Abraham,Pearl Brazier
Issue Date:May 2013
pp. 36-43
With rapid growth of the Semantic Web, the authors' research focuses on designing a scalable resource description framework (RDF) database system that can efficiently process SPARQL queries over large RDF datasets. In this article, they present their desig...
 
The intensity level reduction in radiation therapy
Found in: Proceedings of the 2005 ACM symposium on Applied computing (SAC '05)
By John Abraham, Xiaodong Wu
Issue Date:March 2005
pp. 242-246
In this paper, we study an interesting intensity level reduction (ILR) problem, which is crucial for solving the "step-and-shoot" delivery planning problem in Intensity-Modulated Radiation Therapy (IMRT). IMRT aims to deliver a highly conformal radiation d...
