Data-parallel accelerator devices such as Graphical Processing Units (GPUs) are providing dramatic performance improvements over evenmulti-coreCPUs for lattice-oriented applications in computational physics. Models such as the Ising and Potts models... Read More about Regular lattice and small-world spin model simulations using CUDA and GPUs.

A translation of state machines to temporal fault trees (2010)
Presentation / Conference Contribution
Papadopoulos, Y., Mahmud, N., & Walker, M. (2010, June). A translation of state machines to temporal fault trees. Presented at 2010 International Conference on Dependable Systems and Networks Workshops (DSN-W)

State Machines (SMs) are increasingly being used to gain a better understanding of the failure behaviour of safety-critical systems. In dependability analysis, SMs are translated to other models, such as Generalized Stochastic Petri Nets (GSPNs) or c... Read More about A translation of state machines to temporal fault trees.

Cognitive architectures for affect and motivation (2010)
Journal Article
Davis, D. N. (2010). Cognitive architectures for affect and motivation. Cognitive Computation, 2(3), 199-216. https://doi.org/10.1007/s12559-010-9053-4

General frameworks of mind map across tasks and domains. By what means can a general architecture know when it has adapted to a specific task, a particular environment or a specific state of a previously known environment? Our current work on this th...

Robo-CAMAL: A BDI Motivational Robot (2010)
Journal Article
Davis, D., & Gwatkin, J. (2010). Robo-CAMAL: A BDI Motivational Robot. Paladyn, 1(2), 116-129. https://doi.org/10.2478/s13230-010-0010-4

Motivation is a central concept in the development of autonomous agents and robots. This paper describes an architecture that uses a psychological BDI model of reasoning, combined with a distributed multi-level model of motivation. The robot controll...

Beyond desktop point and click: Immersive walkthrough of aerospace structures (2010)
Presentation / Conference Contribution
Courter, D., Springer, J. P., Neumann, C., Cruz-Neira, C., & Reiners, D. (2010, March). Beyond desktop point and click: Immersive walkthrough of aerospace structures. Presented at 2010 IEEE Aerospace Conference, Big Sky, MT, USA

There are a number of 3D applications that have shown the benefits of using visualization techniques for virtual prototyping and education in aerospace engineering. However,these applications typically run only on desktop computers and user interacti... Read More about Beyond desktop point and click: Immersive walkthrough of aerospace structures.

Generalizable safety annotations for specification of failure patterns (2010)
Journal Article
Papadopoulos, Y., Walker, M., Grunske, L., & Wolforth, I. (2010). Generalizable safety annotations for specification of failure patterns. Software: Practice and Experience, 40(5), 453-483. https://doi.org/10.1002/spe.966

Components in programmable systems often exhibit patterns of failure that are independent of function or system context. In this paper, we show that it is possible to capture, and reuse where appropriate, such patterns for the purposes of system safe...

Reliable decentralized supervisory control of fuzzy discrete event systems (2010)
Journal Article
Wang, F., Feng, Z., & Jiang, P. (2010). Reliable decentralized supervisory control of fuzzy discrete event systems. Fuzzy Sets and Systems, 161(12), 1657-1668. https://doi.org/10.1016/j.fss.2010.02.002

Decentralized supervisory control has been introduced to deal with a class of fuzzy discrete event systems (DES) in which state transitions are uncertain. In this paper, we develop the work on fuzzy DES to consider the reliable decentralized supervis... Read More about Reliable decentralized supervisory control of fuzzy discrete event systems.

 A "Society of Mind" cognitive architecture based on the principles of artificial economics (2010)
Journal Article

This research investigates the concept of mind as a control system using the "Society of Agents" metaphor, whereby the whole is described as the collective behavior of simple and intelligent agents. This powerful concept for mind research benefits fr... Read More about  A "Society of Mind" cognitive architecture based on the principles of artificial economics.

A perceptually relevant approach to ringing region detection (2010)
Journal Article
Liu, H., Klomp, N., & Heynderickx, I. (2010). A perceptually relevant approach to ringing region detection. IEEE Transactions on Image Processing, 19(6), 1414-1426. https://doi.org/10.1109/tip.2010.2041406

An efficient approach toward a no-reference ringing metric intrinsically exists of two steps: first detecting regions in an image where ringing might occur, and second quantifying the ringing annoyance in these regions. This paper presents a novel ap... Read More about A perceptually relevant approach to ringing region detection.
