An architecture for integrated intelligence in urban management using cloud computing (2012)
Journal Article

With the emergence of new methodologies and technologies it has now become possible to manage large amounts of environmental sensing data and apply new integrated computing models to acquire information intelligence. This paper advocates the applicat... Read More about An architecture for integrated intelligence in urban management using cloud computing.

Context caches in the Clouds (2012)
Journal Article

In context-aware systems, the contextual information about human and computing situations has a strong temporal aspect i. e. it remains valid for a period of time. This temporal property can be exploited in caching mechanisms that aim to exploit such... Read More about Context caches in the Clouds.

Risk-driven compliant access controls for clouds (2011)
Presentation / Conference Contribution

There is widespread agreement that cloud computing have proven cost cutting and agility benefits. However, security and regulatory compliance issues are continuing to challenge the wide acceptance of such technology both from social and commercial st...

Towards context caching in the clouds (2011)
Presentation / Conference Contribution

Context information is traditionally collected from distributed digital artifacts and services and made available to similarly distributed, and often mobile, context consuming applications via context brokers or servers. Contextual data has a strong... Read More about Towards context caching in the clouds.

Provenance management for neuroimaging workflows in neuGrid (2011)
Presentation / Conference Contribution

Bridging the gap between business process models and service-oriented architectures with reference to the grid environment (2011)
Journal Article

In recent years, organisations have been seeking technological solutions for enacting their business process models using ad-hoc and heuristic approaches. However, limited results have been obtained due to the expansion of business processes across g...

CMS workflow execution using intelligent job scheduling and data access strategies (2011)
Journal Article

Complex scientific workflows can process large amounts of data using thousands of tasks. The turnaround times of these workflows are often affected by various latencies such as the resource discovery, scheduling and data access latencies for the indi... Read More about CMS workflow execution using intelligent job scheduling and data access strategies.

A fault tolerant, dynamic and low latency BDII architecture for grids (2010)
Journal Article

The current BDII model relies on information gathering from agents that run on each core node of a Grid. This information is then published into a Grid wide information resource known as Top BDII. The Top level BDIIs are updated typically in cycles o... Read More about A fault tolerant, dynamic and low latency BDII architecture for grids.

Research traceability using provenance services for biomedical analysis and the neuGRID consortium (2010)
Book Chapter

Grid infrastructures for computational neuroscience: The neuGRID example (2009)
Journal Article

Neuroscience is increasingly making use of statistical and mathematical tools to extract information from images of biological tissues. Computational neuroimaging tools require substantial computational resources and the increasing availability of la...

Managing the mappings between domain ontologies and database schemas when formulating relational queries (2009)
Presentation / Conference Contribution

In recent years, the tremendous increase in the use of medical knowledge-discovery and decision-support applications has often required clinical researchers to write complex database queries. The users of these data analysis systems are normally unaw... Read More about Managing the mappings between domain ontologies and database schemas when formulating relational queries.

Rule-based querying of distributed, heterogeneous data (2009)
Journal Article

When searching for data, users tend to think in terms of the information they need to retrieve and not where and how it is stored. This is especially true in the highly complex domain of neurological research. The -generic medical querying service de... Read More about Rule-based querying of distributed, heterogeneous data.

Reusable services from the neuGRID project for grid-based health applications (2009)
Presentation / Conference Contribution

By abstracting Grid middleware specific considerations from clinical research applications, re-usable services should be developed that will provide generic functionality aimed specifically at medical applications. In the scope of the
neuGRID projec... Read More about Reusable services from the neuGRID project for grid-based health applications.

Semantic matching using the UMLS (2009)
Journal Article

Ontology assisted query reformulation using the semantic and assertion capabilities of OWL-DL ontologies (2008)
Presentation / Conference Contribution

End users of recent biomedical information systems are often unaware of the storage structure and access mechanisms of the underlying data sources and can require simplified mechanisms for writing domain specific complex queries. This research aims t... Read More about Ontology assisted query reformulation using the semantic and assertion capabilities of OWL-DL ontologies.

Semantic matching for the medical domain (2008)
Presentation / Conference Contribution

This paper proposes some modifications to the SMatch algorithm that enables the semantic matching of medical terminologies using the Unified Medical Language System (UMLS) as a source of background knowledge. Semantic Matching is the process of disco... Read More about Semantic matching for the medical domain.

Using assertion capabilities of an OWL-based ontology for query formulation (2008)
Presentation / Conference Contribution

This paper reports on the development of a framework to assist users in formulating relational queries without requiring a complete knowledge of the information structure and access mechanisms to underlying data sources. The emphasis here is on explo... Read More about Using assertion capabilities of an OWL-based ontology for query formulation.

Medical data integration and the semantic annotation of medical protocols (2008)
Presentation / Conference Contribution

The CMS experiment at the CERN LHC (2008)
Journal Article

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and leadlead)
collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon)... Read More about The CMS experiment at the CERN LHC.
