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...

A rule-based system for programming self-organized sensor and actor networks (2008)
Journal Article
Dressler, F., Dietrich, I., German, R., & Krüger, B. (2009). A rule-based system for programming self-organized sensor and actor networks. Computer Networks, 53(10), 1737-1750. https://doi.org/10.1016/j.comnet.2008.09.007

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.

Steering and visualization: Enabling technologies for computational science (2008)
Journal Article
Wright, H., Crompton, R. H., Kharche, S., & Wenisch, P. (2010). Steering and visualization: Enabling technologies for computational science. Future generations computer systems : FGCS, 26(3), 506-513. https://doi.org/10.1016/j.future.2008.06.015

Computational steering is an investigative paradigm whereby the parameters of a running program can be altered according to what is seen in the currently visualized results of the simulation. For certain problems, interactive computation brings speci... Read More about Steering and visualization: Enabling technologies for computational science.

Improving Interaction Performance for Ray Tracing (2008)
Presentation / Conference Contribution
Kurz, D., Lux, C., Springer, J., & Fröhlich, B. Improving Interaction Performance for Ray Tracing. Presented at Eurographics 2008

We have developed an approach for improving the performance of object manipulation in ray tracing systems.We assume that users alternate between navigating the scene and manipulating objects in the scene. We divide the scene in objects currently mani... Read More about Improving Interaction Performance for Ray Tracing.

Stable quantum filters with scattering phenomena (2008)
Journal Article
Ahamed, W. U., & Kambhampati, C. (2008). Stable quantum filters with scattering phenomena. International Journal of Automation and Computing, 5(2), 132-137. https://doi.org/10.1007/s11633-008-0132-x

Quantum neural network filters for signal processing have received a lot of interest in the recent past. The implementations of these filters had a number of design parameters that led to numerical inefficiencies. At the same time the solution proced...

Object-Capability Security in Virtual Environments (2008)
Presentation / Conference Contribution
Scheffler, M., Springer, J. P., & Froehlich, B. (2008, March). Object-Capability Security in Virtual Environments. Presented at 2008 IEEE Virtual Reality Conference

Access control is an important aspect of shared virtual environments.Resource access may not only depend on prior authorization, but alsoon context of usage such as distance or position in the scene graphhierarchy. In virtual worlds that allow user-c... Read More about Object-Capability Security in Virtual Environments.

Linking perception and action through motivation and affect (2008)
Journal Article
Davis, D. N. (2008). Linking perception and action through motivation and affect. Journal of Experimental and Theoretical Artificial Intelligence, 20(1), 37-60. https://doi.org/10.1080/09528130701472424

Research into cognitive architectures is described within a framework spanning major issues in artificial intelligence and cognitive science. Earlier work on motivation is extended with a cognitive model of reasoning which, together with an affective... Read More about Linking perception and action through motivation and affect.

Autonomous clustering using rough set theory (2008)
Journal Article
Bean, C., & Kambhampati, C. (2008). Autonomous clustering using rough set theory. International Journal of Automation and Computing, 5(1), 90-102. https://doi.org/10.1007/s11633-008-0090-3

This paper proposes a clustering technique that minimizes the need for subjective human intervention and is based on elements of rough set theory (RST). The proposed algorithm is unified in its approach to clustering and makes use of both local and g... Read More about Autonomous clustering using rough set theory.

Haptic feedback can provide an objective assessment of arthroscopic skills (2008)
Journal Article
Chami, G., Ward, J. W., Phillips, R., & Sherman, K. P. (2008). Haptic feedback can provide an objective assessment of arthroscopic skills. Clinical orthopaedics and related research, 466(4), 963-968. https://doi.org/10.1007/s11999-008-0115-9

The outcome of arthroscopic procedures is related to the surgeon's skills in arthroscopy. Currently, evaluation of such skills relies on direct observation by a surgeon trainer. This type of assessment, by its nature, is subjective and time-consuming... Read More about Haptic feedback can provide an objective assessment of arthroscopic skills.
