An Optimal Strategy for Cooperative Spectrum Sensing in Cognitive Radio Networks

Ali H. Sayed

Spectrum sensing is a key enabling functionality in cognitive radio (CR) networks, where the CRs act as secondary users that opportunistically access free frequency bands. Due to the effects of channel fading, individual CRs may not be able to reliably det ...

Stable computation of probability densities for metastable dynamical systems

Lionel Walter

Whenever the invariant stationary density of metastable dynamical systems decomposes into almost invariant partial densities, its computation as eigenvector of some transition probability matrix is an ill-conditioned problem. In order to avoid this computa ...

Anisotropy factor of saturated and unsaturated soils

Dani Or

Variations in the degree of anisotropy in soil hydraulic conductivity with changes in water saturation (S-e) may adversely impact predictability of flow and transport processes. The conceptual "layered cake'' model was extended to consider effects of bulk ...

Map-matching for pedestrians via Bayesian inference

Michel Bierlaire, Bertrand Merminod

A navigation process is to start from a known (initial) position and to ensure a continued localisation of the user during the movement. Consider a pedestrian navigation system which contains a GPS receiver and a set of inertial sensors connected with the ...

Bayesian Inference for Autonomous Personal Localisation Indoors

Michel Bierlaire, Bertrand Merminod

The principal concept of navigation is to start from a known (initial) position and to ensure a continued and reliable localisation of the user during his/her movement. The initial position of the trajectory is usually obtained via GPS or defined by the us ...

Statistical description of sediment transport experiments

Christophe Ancey, Peter Frey

A longstanding problem in the study of sediment transport in gravel-bed rivers is related to the physical mechanisms governing bed resistance and particle motion. To study this problem, we investigated the motion of coarse spherical glass beads entrained b ...

Stochasticity of probabilistic systems: Analysis methodologies case-study

Karl Aberer, Martin Hasler, Abhisek Datta

We do a case study of two different analysis techniques for studying the stochastic behavior of a randomized system/algorithms: (i) The first approach can be broadly termed as a mean value analysis (MVA), where the evolution of the mean state is studied as ...

Impact of Sample Sizes on Information Theoretic Measures for Audio-Visual Signal Processing

Jean-Philippe Thiran, Ninoslav Marina, Ivana Arsic de Heras Ciechomska

In this paper we aim to explore what is the most appropriate number of data samples needed when measuring the temporal correspondence between a chosen set of video and audio cues in a given audio-visual sequence. Presently the optimal model that connects s ...

Uncertainty analysis for the steady-state flows in a dual throat nozzle

Jan Sickmann Hesthaven

It is well known that the steady state of an isentropic flow in a dual-throat nozzle with equal throat areas is not unique. In particular there is a possibility that the flow contains a shock wave, whose location is determined solely by the initial conditi ...
