A Task Orientated Requirements Ontology for Cloud Computing Services (2016)
Presentation / Conference Contribution
Greenwell, R., Liu, X., Chalmers, K., & Pahl, C. (2016). A Task Orientated Requirements Ontology for Cloud Computing Services. In Proceedings of the 6th International Conference on Cloud Computing and Services Science (CLOSER 2016) (121-128). https://doi

Requirements ontology offers a mechanism to map requirements for cloud computing services to cloud computing resources. Multiple stakeholders can capture and map knowledge in a flexible and efficient manner. The major contribution of the paper is the...

Pricing Ontology for Task-Oriented Cloud Sourcing (2016)
Presentation / Conference Contribution
Greenwell, R., Liu, X., & Chalmers, K. (2016). Pricing Ontology for Task-Oriented Cloud Sourcing. In 2016 IEEE 4th International Conference on Future Internet of Things and Cloud (FiCloud). https://doi.org/10.1109/ficloud.2016.17

Cloud computing allows access to computing resources from a number of providers, who offer multiple pricing strategies for selected product characteristics. The service offerings are becoming increasingly complex, with innovations such as spot market... Read More about Pricing Ontology for Task-Oriented Cloud Sourcing.

Semantic description of cloud service agreements (2015)
Presentation / Conference Contribution
Greenwell, R., Liu, X., & Chalmers, K. (2015). Semantic description of cloud service agreements. In Science and Information Conference (SAI), 2015 (823-831). https://doi.org/10.1109/sai.2015.7237239

To provide cloud services as a utility there must be a mechanism for comprehensively and precisely specifying cloud service agreements to reduce differences in service perception between customers and suppliers. This paper proposes a description... Read More about Semantic description of cloud service agreements.

Visual techniques to support exploratory analysis of temporal graph data. (2015)
Presentation / Conference Contribution
Kerracher, N., Kennedy, J., Chalmers, K., & Graham, M. (2016, May). Visual techniques to support exploratory analysis of temporal graph data. Presented at EuroVis '15

Recently, much research has focused on developing techniques for the visual representation of temporal graph data. This paper takes a wider look at the visual techniques involved in exploratory analysis of such data, considering the variety of sub ta...

A Task Taxonomy for Temporal Graph Visualisation (2015)
Journal Article
Kerracher, N., Kennedy, J., & Chalmers, K. (2015). A Task Taxonomy for Temporal Graph Visualisation. IEEE Transactions on Visualization and Computer Graphics, 21(10), 1160-1172. https://doi.org/10.1109/tvcg.2015.2424889

By extending and instantiating an existing formal task framework, we define a task taxonomy and task design space for temporal graph visualisation. We discuss the process involved in their generation, and describe how the design space can be ‘sliced... Read More about A Task Taxonomy for Temporal Graph Visualisation.

Collaborative Diffusion on the GPU for Path-Finding in Games (2015)
Presentation / Conference Contribution
McMillan, C., Hart, E., & Chalmers, K. (2015). Collaborative Diffusion on the GPU for Path-Finding in Games. In A. M. Mora, & G. Squillero (Eds.), Applications of Evolutionary Computation; Lecture Notes in Computer Science (418-429). https://doi.org/10.10

Exploiting the powerful processing power available on the GPU in many machines, we investigate the performance of parallelised versions of pathfinding algorithms in typical game environments. We describe a parallel implementation of a collaborative d... Read More about Collaborative Diffusion on the GPU for Path-Finding in Games.

Poxels: polygonal voxel environment rendering (2014)
Presentation / Conference Contribution
Miller, M., Cumming, A., Chalmers, K., Kenwright, B., & Mitchell, K. (2014). Poxels: polygonal voxel environment rendering. In Proceedings of the 20th ACM Symposium on Virtual Reality Software and Technology - VRST '14 (235-236). https://doi.org/10.1145/

We present efficient rendering of opaque, sparse, voxel environments with data amplified in local graphics memory with stream-out from a geomery shader to a cached vertex buffer pool. We show that our Poxel rendering primitive aligns with optimized r... Read More about Poxels: polygonal voxel environment rendering.

The design space of temporal graph visualisation. (2014)
Presentation / Conference Contribution
Kerracher, N., Kennedy, J., & Chalmers, K. (2014). The design space of temporal graph visualisation. In N. Elmqvist, M. Hlawitschka, & J. Kennedy (Eds.), Proceedings of the 18th Eurographics Conference on Visualization (EuroVis '14). https://doi.org/10.23

This paper presents our work in mapping the design space of techniques for temporal graph visualisation. We identify two independent dimensions upon which the techniques can be classified: graph structural encoding and temporal encoding. Based on the...
