Probabilistic structure of the distance between tributaries of given size in river networks

We analyze the distribution of the distances between tributaries of a given size (or of sizes larger than a given area) draining along either an open boundary or the mainstream of a river network. By proposing a description of the distance separating presc ...

Existence, cost and robustness of spatial small-world networks

Paolo De Los Rios, Thomas Petermann

Small-world networks embedded in Euclidean space represent useful cartoon models for a number of real systems such as electronic circuits, communication systems, the large-scale brain architecture and others. Since the small-world behavior relies on the pr ...

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 ...

The scaling of the broadcast capacity of extended wireless networks with cooperative relays

Michael Christoph Gastpar

We study the scaling of the broadcast capacity for a network with a single source and f(N) cooperative relays where N is the number of destinations and f(.) is an increasing function. We consider random extended networks (the network area goes to infinity ...

Validation of the performance of a new bidirectional video-goniophotometer

Marilyne Andersen

An accurate knowledge of the directional optical properties of advanced fenestration materials is necessary for them to be adequately integrated in buildings. These properties are expressed by the Bidirectional Transmission (or Reflection) Distribution Fun ...

Anisotropic pressure bi-Maxwellian distribution function model for three-dimensional equilibria

Jonathan Graves, Wilfred Anthony Cooper

A formulation of the anisotropic pressure magnetohydrodynamic equilibrium problem for three-dimensional plasmas with imposed nested magnetic surfaces is developed based on a bi-Maxwellian model of the distribution function for the energetic particle specie ...

On the definition of a kinetic equilibrium in global gyrokinetic simulations

Olivier Sauter, Laurent Villard, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Paolo Angelino

Nonlinear electrostatic global gyrokinetic simulations of collisionless ion temperature gradient (ITG) turbulence and ExB zonal flows in axisymmetric toroidal plasmas are examined for different choices of the initial distribution function. Using a local Ma ...

Numerical study of models of quantum chaos

This work is dedicated to the study of models of quantum chaos. It is clear that one cannot define chaos in quantum mechanics the same way it is defined in classical dynamics. The classical definition of chaos relies upon the ideas of sensitive dependence ...

Raptor Codes on Binary Memoryless Symmetric Channels

Mohammad Amin Shokrollahi, Seyed Omid Etesami

In this paper, we will investigate the performance of Raptor codes on arbitrary binary input memoryless symmetric channels (BIMSCs). In doing so, we generalize some of the results that were proved before for the erasure channel. We will generalize the stab ...

Three-dimensional anisotropic pressure equilibria that model balanced tangential neutral beam injection effects

Wilfred Anthony Cooper

Fixed boundary three-dimensional anisotropic pressure equilibria are computed that are consistent with a family of distribution functions that load particles preferentially towards v parallel to similar or equal to v and model the effects of balanced tange ...
