This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may(More)
In this paper, we give a status report of a real-world application scenario that uses two distinct types of workflow within the Triana problem solving environment: serial scientific workflow for the data processing of gravitational waves signals; and the distributed workflows that dynamically map to the virtual Grid overlay of Triana services. We briefly(More)
Service composition refers to the aggregation of services to build complex applications to achieve client requirements. It is an important challenge to make it possible for users to construct complex workflows transparently and thereby insulating them from the complexity of interacting with numerous heterogeneous services. We present an extension to the(More)
In this paper, we describe the graphical abstractions for Grids and services that have been implemented within the Triana problem solving environment. We provide an overview of the ways in which Triana interacts with services (e.g., Web and P2P services) and then how we interact with core Grid components, such as resource managers and data management(More)
Burkholderia (Pseudomonas) cepacia PR1(23) has been shown to constitutively express to toluene catabolic pathway distinguished by a unique toluene ortho-monooxygenase (Tom). This strain has also been shown to contain two extrachromosomal elements of < 70 and > 100 kb. A derivative strain cured of the largest plasmid, PR1(23) Cure, was unable to grow on(More)
We discuss here a parallel implementation of the visual-isation of data from a galaxy formation simulation within the Triana problem-solving environment. The visualisa-tion is a test case for our prototype Triana Grid software using a decentralized Peer-to-Peer approach. The Triana distributed environment is middleware independent and designed in such a way(More)
An overview of the Triana Problem Solving Environment is provided – with a particular focus on the GAP application-level interface, for integration with Grid Computing and Peer-to-Peer infrastructure. GAP is a Java-based subset of the Grid Application Toolkit interface (being implemented in the GridLab project), and an outline of its current functionality,(More)
Tn5 insertion mutants of Pseudomonas cepacia G4 that were unable to degrade trichloroethylene (TCE), toluene, or phenol or to transform m-trifluoromethyl phenol (TFMP) to 7,7,7-trifluoro-2-hydroxy-6-oxo-2,4-heptadienoic acid (TFHA) were produced. Spontaneous reversion to growth on phenol or toluene as the sole source of carbon was observed in one mutant(More)
