We introduce Trident, a scientific workflow workbench that is built on top of a commercial workflow system to leverage existing functionality. Trident is being developed in collaboration with the scientific community for use in a number of ongoing escience projects that make use of scientific workflows.
Cloud computing has emerged as a new approach to large scale computing and is attracting a lot of attention from the scientific and research computing communities. Despite its growing popularity, it is still unclear just how well the cloud model of computation will serve scientific applications. In this paper we analyze the applicability of cloud to the… (More)
Microsoft robotics studio (MSRS) was publicly released in December 2006 with the explicit goal of providing an industry software standard for robot control. To become a viable standard, several technical challenges needed to be solved. In this article, we examine the composition of MSRS, looking generally at its architecture and specifically at its… (More)
Automated extraction of structured Web data has attracted considerable interest in both the academia and industry. A particularly promising approach is to employ XML technologies to translate semi-structured HTML documents to " pure " XML documents. In this approach, HTML documents are first normalized into XHMTL and then mapped to the desired XML… (More)
We introduce Trident, a scientific workflow workbench that is built on top of a commercial workflow system to leverage existing functionality. Trident is being developed in collaboration with the scientific community for oceanography, but the workbench itself can be used for any science project for scientific workflow.
Two series of (N-benzylpiperidin-4-yl)- and (9-azabicyclo[3.3.1]nonan- 3 beta-yl)benzamides were prepared, and in vitro binding assays were used to measure the affinity of these compounds for dopamine D2, dopamine D3, serotonin 5-HT2, and alpha 2-adrenergic receptors. The results of these studies indicated compounds 23, 26b, and 34 have the selectivity… (More)
To effectively support real-time monitoring and performance analysis of scientific workflow execution, varying levels of event data must be captured and made available to interested parties. This paper discusses the creation of an ontology-aware workflow monitoring system for use in the Trident system which utilizes a distributed publish/subscribe event… (More)
Leveraging cloud computing to acquire the necessary computation resources to scale out parallel applications is becoming common practice. However, many such applications also require communication and synchronization between processes. Although, commercial cloud platforms provide ready access to scalable compute and storage services, implementing… (More)
A mobile instrument system was used to measure energy consumption by indirect calorimetry at rest and during ambulation in 25 unimpaired subjects, 6 unilateral below-knee (BK) amputee patients, 6 unilateral above-knee (AK) amputee patients and 4 bilateral AK amputee patients. To prevent the introduction of gait difficulties among the impaired subjects, each… (More)
