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?.

Improving the bottom line: Moving towards a transport capability maturity model (2008)
Conference Proceeding
Holter, A., Millar Ritchie, J., Shaw, W. N., & Grant, D. (2008). Improving the bottom line: Moving towards a transport capability maturity model. In Logistics Research Network Annual Conference 2008 - Liverpool, United Kingdom, 14-19

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.

Improving service and sustainability in retail supply chains (2008)
Conference Proceeding
Grant, D. B., Fernie, J., Tautrims, A., & El-Adas, R. (2008). Improving service and sustainability in retail supply chains. In Proceedings of the 13th International Symposium on Logistics (ISL) 2008, 257-264

Purpose: On-shelf availability and its impact on retail customer service and profitability has concerned retailers for many years. Further, globalisation of retail supply chains has meant increased logistics costs, particularly in transportation, and...

Tanskanen (Eds.), Beyond Business Logistics : Selected full papers presented at the 20th Anniversary NOFOMA 2008 logistics conference held in June 2008 at Hanken (the Swedish School of Economics and Business Administration) in Helsinki, Finland, 297-312

Semi automatic failure analysis based on simulation models (2008)
Conference Proceeding
Hamann, R., Uhlig, A., Papadopoulos, Y., Rüde, E., Grätz, U., Walker, M., & Lien, R. (2008). Semi automatic failure analysis based on simulation models. . https://doi.org/10.1115/omae2008-57256

Classical risk assessment and risk management which is gaining importance in many industries is usually based on well defined processes and uses techniques like FTA and FMEA. However, classical risk analysis techniques like FTA and FMEA should ideall... Read More about Semi automatic failure analysis based on simulation models.

A language for failure patterns and application in safety analysis (2008)
Conference Proceeding
Wolforth, I., Walker, M., & Papadopoulos, Y. (2008). A language for failure patterns and application in safety analysis. . https://doi.org/10.1109/depcos-relcomex.2008.44

Components and families of components in mechatronic systems often exhibit failure characteristics that are independent of system context and repeatable across applications. In this paper, we show that it is possible to capture and reuse such pattern... Read More about A language for failure patterns and application in safety analysis.

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...

Advanced multi-frame rate rendering techniques (2008)
Conference Proceeding
Springer, J. P., Lux, C., Reiners, D., & Froehlich, B. (2008). Advanced multi-frame rate rendering techniques. . https://doi.org/10.1109/VR.2008.4480770

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.

Improving Interaction Performance for Ray Tracing (2008)
Conference Proceeding
Kurz, D., Lux, C., Springer, J., & Fröhlich, B. (2008). Improving Interaction Performance for Ray Tracing. In Eurographics 2008 - Short papers (283 - 286). https://doi.org/10.2312/egs.20081031

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)
Conference Proceeding
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.
