Applications in Diabetic Retinopathy
The STFC funded TRIACS project will create a first-step pilot for a Web Services-based workflow decision support system to exploit the extensively used service-oriented architecture (SOA) infrastructure undertaken within the Triana Workflow Environment project (http://www.trianacode.org/). The existing Triana Web Services framework has been used in a number of other international projects (e.g. GridLab, FAEHIM, Catnets) for Web Services composition. TRIACS intends to transfer this knowledge and experience into the retinopathy field, by partnering with the National Diabetic Retinopathy Screening Service for Wales (DRSSW), an international centre of excellence in distributed-site retinopathy screening. The resulting prototype will provide a demonstrator that will enable researchers at the Diabetes Research Unit to build decision support applications by using a standard graphical drag and drop user interfaces for wiring retinopathy components together to create diagnostic workflows combining multiple specialised (geographically-distributed) information 'silos'.
EDGeD is an EU FP7 project that is setting up infrastructure and building software to enable the integration of Service Grids, or traditional Grid environments such as clusters and supercomputers, and Desktop Grid systems, like the popular volunteer computing project BIONIC. To this aim, EDGeS is working to build an integrated Grid infrastructure across Europe that seemlessly integrates a variety of Desktop Grids with EGEE type of Service Grids. More information about the EDGeS project can be found under http://www.edges-grid.eu
The WHIP project will provide a software plugin utility to enable the interaction between workflow environments and portals.
The goals follow the myExperiment paradigm (http://www.myexperiment.org/), allowing scientists to share their research in a
workflow-centric collaborative and portal-enabled environment.
This proposal is in synergy with existing efforts being undertaken within the myExperiment project, Taverna, Triana, RAVE and PSNC, with the following goals in mind: (i) to create a usable and robust service-based toolkit for exposing workflow environments from within portals; and (ii) to facilitate the composition, editing and community publication of workflow descriptions and their associated semantics.
Specifically, WHIP is building a toolkit for enabling portals or Web sites to execute local applications from within the browser by associating (pairing) applications and workflow environments with bundles that contain applications, data or metadata. When a user click a bundle, the WHIP plug-in launches in order to invoke a local application. WHIP is currently being paired to host Taverna and Triana workflows and is currently being integrated into the myExperiment portal and Gridsphere portals.
This eight month mini-PIPSS project proposal aims to consolidate existing research undertaken within the
Triana Workflow Environment1 with existing Music Information Retrieval (MIR) techniques in order to
create a proof of concept distributed MIR system for commercial exploitation through Synchroarts, a
cutting-edge audio technology company. The resulting DART system will be made freely available to the
public and provide users with an innovative music recommendation system that recommends music based on what audio users
actually have on their home computers rather than sales statistics or music charts, limited to a restricted user base.
DART will be a springboard for further commercialisation, which will capitalise on DART's user base and advance the
software with MIR audio-content analysis algorithms that will be used to make a professional edition of the software for resale.
The proposed Distributed Audio Retrieval using Triana (DART) pro ject will create an MIR system capable of making music recommendations based on statistical analysis using well known collaborative filtering techniques. Existing research at Cardiff is already been undertaken independently in each of these areas and this pro ject converges these activities in order to create a core MIR framework capable of hosting next-generation algorithms for Internet level distributed information retrieval through the analysis of audio content rather than relying on metadata tags currently employed in systems with similar intent. DART has many commercial prospects and to focus this work we will be engaging SynchroArts, a leading audio company to advise and steer the project to help identify the necessary aspects needed in order to proceed to the next level of MIR deployment for commercialisation.
The Triana workflow programming environment is used or has been used within a number of projects and research groups, this list is a selection of those projects.
GridOneD is based around the Triana software and is focused on creating open source middleware components for use within Triana and other applications wishing to become grid enabled. GridOneD also extends Triana to supply services for integrating Gravitational Wave search codes. It is using the GAP/GAT and various Gridlab services to implement a production scenario for Grid computing for searching for inspiral binaries and for data mining applications. The second phase of GridOneD is about to start and involves a collaboration between Cardiff University and Manchester University Jodrell Bank Observatory applying existing signal processing techniques in Triana to radio astronomy.

GEO 600 is the main customer for GridOneD. The GEO 600 project aims at the direct detection of gravitational waves by means of a laser interferometer of 600m arm length. Gravitational waves are extremely small ripples in the structure of space-time caused by astrophysical events like supernovae or coalescing binaries.

BiodiversityWorld is a joint collaboration between the Universities of Cardiff, Reading and Southampton, and the Natural History Museum. BiodiversityWorld is a three-year e-Science Pilot Project funded by the BBSRC to create a GRID-based problem solving environment. This PSE is planned for collaborative exploration and analysis of global biodiversity patterns. Example applications would be modeling species distributions against climate change, conservation prioritising and linking evolutionary changes to past climates. The PSE uses Triana to choreograph custom web services into applications.

Environmental scientists work with very large datasets on the terabyte scale. It is necessary to handle these datasets in an efficient manner. We are creating a system in which workflows can be composed and run from any Web Service-based workflow engine (e.g. Triana). In these workflows, data are streamed directly from one remote service to another, avoiding the overhead of caching intermediate results on disk. We use the Inferno operating system as a lightweight middleware layer to handle the data streaming. The system also allows us to monitor changes in the state (e.g. the progress) of the remote services.

The DART project (Distributed Audio Rendering using Triana) explores the potential uses of Grid-computing technologies towards sound computation and music synthesis. Our team of researchers is using Triana to control a cluster of 24 Apple Xserve computers in order to demonstrate the potential of distributed audio rendering over a gigabit network. We are developing software objects that will function much like unit generators, software instruments or effects processors that can run simultaneously or in parallel on different machines across a common network. Ultimately, we envision a Web-services or peer-to-peer virtual sound design engine or synthesizer to which anyone on the Web can subscribe, utilize and provide component parts.
