Clouds are rapidly joining high-performance Grids as viable computational platforms for scientific exploration and discovery, and it is clear that production computational infrastructures will integrate both these paradigms in the near future. As a result, understanding usage modes that are meaningful in such a hybrid infrastructure is critical. For example, there are interesting application workflows...
The following topics are dealt: arts: social science; humanities; bioinformatics; digital repositories; data management; e-science; education; physical science.
CLAROS (Classical Art Research Online Services; www.clarosweb.org) is an international interdisciplinary research initiative led by the University of Oxford (Humanities and Mathematics and Physical Sciences), hosted by the Oxford e-Research Centre (OeRC, www.oerc.ox.ac.uk), and inspired by the Beazley Archive (www.beazley.ox.ac.uk) participating in EU R&D projects. During 2009, a pump-priming...
Interactive multimedia and human-computer interaction technologies are effecting and contributing towards a wide range of developments in many different subject areas including contemporary performing arts. These technologies have facilitated the developments and advancements of augmented and virtual instruments for interactive music performance, interactive installation, many aspects of technology-enhanced...
The research reported in this paper is part of the activities carried out within the CLARIN (common language resources and technology infrastructure) project, a large-scale pan-European project to create, coordinate and make language resources and technologies (LRT) available and readily useable. CLARIN is devoted to the creation of a persistent and stable infrastructure serving the needs of the European...
A phylogenetic or evolutionary tree is constructed from a set of species or DNA sequences and depicts the relatedness between the sequences. Predictions of future sequences in a phylogenetic tree are important for a variety of applications including drug discovery, pharmaceutical research and disease control. In this work, we predict future DNA sequences in a phylogenetic tree using cellular automata...
Behavioural interventions packages of advice and support for behaviour change are one of the most important methodologies and technologies employed by social scientists for understanding and changing behaviour. A typical web-based behavioural intervention study includes the designing, deploying, piloting and trialling of the intervention as well as data analysis. We have developed a research environment...
In this study, we apply a methodology for rapid development of portlets for scientific computing to the domain of computational chemistry. We report results in terms of the portals delivered, the changes made to our methodology and the experience gained in terms of interaction with domain-specialists. Our major contributions are: several web portals for teaching and research in computational chemistry;...
Most workflow based applications currently have to adapt to available tools. While this keeps the cost of development low, it can lead to performance and flexibility tradeoffs that the application developer and deployer must make. In this paper, we use the Montage astronomical image mosaicking application as prototypical DAG-based workflow application to layout the development and deployment decisions...
This paper first provides an overview of the e-research environment in Australia, before introducing the two organizations (the Australian National Data Service-ANDS, and the Australian Research Collaboration Services-ARCS) whose services will be focus of the paper. Next the paper describes the problem that needs to be solved before talking about the requirements for management of data and metadata...
Every modern portal ships with some form of internal document library portlet tools that can be used to enable groups to share files. Unfortunately, certain limitations - that the portlet can only view data managed directly by the portal and that document and data files are the only resource that can be browsed - make these tools less valuable in many real-world collaborations. This paper describes...
Complex networks from domains like Biology or Sociology are present in many e-Science data sets. Dealing with networks can often form a workflow bottleneck as several related algorithms are computationally hard. One example is detecting characteristic patterns or "network motifs" - a problem involving subgraph mining and graph isomorphism. This paper provides a review and runtime comparison...
Mobile devices as the iPhone and Android-based smartphones can be turned into useful tools for researchers in the field. The concept of a scholarly or scientific workbench can be extended by a mobile usage scenario, where the researcher takes photographs, records sounds, and performs basic metadata editing. We present the prototype and the architecture of a mobile workbench that uploads geo-tagged...
Independent, greedy collection of data events using simple heuristics results in massive over-sampling of the prominent data features in large-scale studies over what should be achievable through ??intelligent", online acquisition of such data. As a result, data generated are more aptly described as a collection of a large number of small experiments rather than a true large-scale experiment...
Image analysis researchers would benefit considerably by sharing and reusing image processing algorithms. We consider some of the issues that researchers face in trying to provide algorithms in a shareable and reusable form illustrating our approach in the context of medical imaging needs and workflow for colorectal cancer. We consider the use of workflow as a model for developing and reusing components...
Accessing, running and sharing applications and data presents researchers with many challenges. Cloud computing and social networking technologies have the potential to simplify or eliminate many of these challenges. Cloud computing technologies can provide scientists with transparent and on-demand access to applications served over the Internet in a dynamic and scalable manner. Social networking...
Many of today's large-scale scientific projects attempt to collect data from a diverse set of sources. The traditional campaign-style approach to ??synthesis?? efforts gathers data through a single concentrated effort, and the data contributors know in advance exactly who will use their data and why. At even moderate scales, the cost and time required to find, gather, collate, normalize, and customize...
The concept of topology-aware grid applications is derived from parallelized computational models of complex systems that are executed on heterogeneous resources, either because they require specialized hardware for certain calculations, or because their parallelization is flexible enough to exploit such resources. Here we describe two such applications, a multi-body simulation of stellar evolution,...
