Improving the bottom line: Moving towards a transport capability maturity model (2008)
Conference Proceeding

Transport is often considered a service that can easily be purchased and obtained without further complications. However, managing and purchasing transport is a complex process. A five step transport purchasing capability maturity model is proposed w... Read More about Improving the bottom line: Moving towards a transport capability maturity model.

Spiking neurons: Is coincidence-factor enough for comparing responses with fluctuating membrane voltage? (2008)
Conference Proceeding
Sarangdhar, M., & Kambhampati, C. (2008). Spiking neurons: Is coincidence-factor enough for comparing responses with fluctuating membrane voltage?. In Proceedings of the World Congress on Engineering (1640 - 1645)

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?.

Simulation and static measurement of the gas volume fraction in a separated flow model using a conductance multiphase Venturi meter (CMVM) (2008)
Conference Proceeding
Hasan, A., & Lucas, G. (2008). Simulation and static measurement of the gas volume fraction in a separated flow model using a conductance multiphase Venturi meter (CMVM). In Proceedings of Computing and Engineering Annual Researchers' Conference 2008: CEARC’08 (69-74)

The assumption of equal mixture densities at the inlet and the throat of the Venturi is only valid in a homogenous flow. This assumption is no longer valid for a separated flow and therefore, the measurement of the gas volume fraction at the throat m...

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.

Object-Capability Security in Virtual Environments (2008)

Scheffler, M., Springer, J. P., & Froehlich, B. (2008). Object-Capability Security in Virtual Environments. . https://doi.org/10.1109/vr.2008.4480750

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.

Polygon smoothing nurbs curves and surfaces (2005)
Conference Proceeding
Li, Q. (2005). Polygon smoothing nurbs curves and surfaces. In Proceeding. Applied Simulation and Modelling (ASM 2005) (109 - 114)

In conventional spline geometric shape design, each part of a designed object always evolves the same number of con trol points. This has been a disadvantage of the spline based geometric shape design schemes as much more points than necessary may be... Read More about Polygon smoothing nurbs curves and surfaces.
