IFAC Proceedings Volumes/ International Federation of Automatic Control, 41(3), 199-204. https://doi.org/10.3182/20081205-2-cl-4009.00036

The optimal satisfaction of dependability attributes and cost, in the design of engineering systems, is a hard multi-objective optimization problem which requires automated algorithms that can effectively search large design spaces. In this paper, a... Read More about Multi-objective optimization of dependability attributes using an asynchronous heterogeneous hierarchical parallel genetic algorithm.

Spiking neurons: Is coincidence-factor enough for comparing responses with fluctuating membrane voltage? (2008)
Presentation / Conference Contribution
Sarangdhar, M., & Kambhampati, C. Spiking neurons: Is coincidence-factor enough for comparing responses with fluctuating membrane voltage?

Similarity between two spike trains is generally estimated using a ‘coincidence factor’. This factor relies on counting coincidences of firing-times for spikes in a given time window. However, in cases where there are significant fluctuations in memb... Read More about Spiking neurons: Is coincidence-factor enough for comparing responses with fluctuating membrane voltage?.

Virtual reality training for radiotherapy becomes a reality (2008)
Journal Article

The cubic Segre variety in PG(5,2) (2008)
Journal Article
Shaw, R., & Gordon, N. A. (2009). The cubic Segre variety in PG(5,2). Designs, codes, and cryptography, 51(2), 141-156. https://doi.org/10.1007/s10623-008-9250-2

The Segre variety S 1,2 in PG(5, 2) is a 21-set of points which is shown to have a cubic equation Q(x) = 0. If T(x, y, z) denotes the alternating trilinear form obtained by completely polarizing the cubic polynomial Q, then the associate U # of an r-... Read More about The cubic Segre variety in PG(5,2).

Non-coherent modelling in compositional fault tree analysis (2008)
Presentation / Conference Contribution
Sharvia, S., & Papadopoulos, Y. I. Non-coherent modelling in compositional fault tree analysis

The inclusion of NOT gates in a fault tree creates a 'non-coherent' structure in which not only the failure of a component but also the negation of failure, i.e. the working state of the component, can contribute to the undesirable effects on a syste...

Risk-sensitive antipredator behavior in the Trinidadian guppy, Poecilia reticulata (2008)
Journal Article
Botham, M. S., Hayward, R. K., Morrell, L. J., Croft, D. P., Ward, J. R., Ramnarine, I., & Krause, J. (2008). Risk-sensitive antipredator behavior in the Trinidadian guppy, Poecilia reticulata. Ecology, 89(11), 3174-3185. https://doi.org/10.1890/07-0490.1

The comparative approach has become a powerful tool for understanding how predation has shaped prey behavior. In this study we recorded the occurrence of common aquatic predator species and their densities in seven natural populations of Trinidadian...

We describe a programming scheme for massively distributed systems that are assumed to self-organize according to a given set of simple rules. The focus of this investigation is operation and control in sensor and actor networks (SANETs). The main is...

Advanced multi-frame rate rendering techniques (2008)
Presentation / Conference Contribution
Springer, J. P., Lux, C., Reiners, D., & Froehlich, B. Advanced multi-frame rate rendering techniques. Presented at Proceedings - IEEE Virtual Reality

Multi-frame rate rendering is a parallel rendering technique that renders interactive parts of the scene on one graphics card while the rest of the scene is rendered asynchronously on a second graphics card. The resulting color and depth images of bo... Read More about Advanced multi-frame rate rendering techniques.
