On Burst Loss in Optical Burst Switched Networks with Hot Potato Deflection Routing
In this article we investigate the effects of increased Control Packet lead Time (CPT) on the loss probability of bursts in an OBS network with deflection routing. In particular w...

An OFDM Symbol Design for Reduced Complexity MMSE Channel Estimation
In this paper we revisit the minimum mean square error (MMSE) pilot-aided channel estimation for broadband orthogonal frequency division multiplexing (OFDM) systems. The careful de...

Patterns of oscillation in a Ring of Identical Cells with Delayed Coupling
We investigate the behaviour of a neural network model consisting of three neurons with delayed self and nearest-neighbour connections. We give analytical results on the existence...

Spatial Orientation in Virtual Environments: Background Considerations and Experiments
Spatial orientation strongly relies on visual and whole-body information available while moving through space. As virtual environments allow to isolate the contribution of visual i...
