An ant-based rate allocation algorithm for media streaming in peer to peer networks: extension to multiple sessions and dynamic networks

In this paper, we introduce a novel algorithm for rate allocation in media stream- ing P2P networks where multimedia contents are distributed among network members and streamed toward any requesting peer. The proposed algorithm is based on ant-colony optim ...

Processing strategies for high-resolution GPR concrete inspections

Alexis Kalogeropoulos

A high-resolution multi-sensor and multi-polarization Ground Penetrating Radar (GPR) dataset was acquired on a concrete retaining wall. This dataset was characterised as a low pass filter with the help of a moving window spectral analysis. In order to exam ...

Structural identification through continuous monitoring: data cleansing using temperature variations

Ian Smith, Irwanda Laory

The aim of structural performance monitoring is to infer the state of a structure from measurements and thereby support decisions related to structural management. Complex structures may be equipped with hundreds of sensors that measure quantities such as ...

The Gigavision Camera

Martin Vetterli, Edoardo Charbon, Sabine Süsstrunk, Luciano Sbaiz, Yue Lu, Feng Yang

We study a new image device called gigavision camera or the gigapixel digital film camera. The main differences between a conventional and a gigavision camera are that the pixels of the latter are binary and orders of magnitude smaller. A gigavision camera ...

METHOD, APPARATUS AND COMPUTER PROGRAM FOR ADAPTIVE COMPENSATION OF A MTF

Albrecht Johannes Lindner

A method and system for adaptively compensating for the printer MTF. The MTF compensation applied locally depends on the local mean: Several compensated High-pass images are computed for different mean values. Then locally, depending on the value of the lo ...

IMPEDANCES OF AN INFINITELY LONG AND AXISYMMETRIC MULTILAYER BEAM PIPE: MATRIX FORMALISM AND MULTIMODE ANALYSIS

Nicolas Frank Mounet

Using B. Zotter’s formalism, we present here a novel, efficient and exact matrix method for the field matching determination of the electromagnetic field components created by an offset point charge travelling at any speed in an infinitely long circular mu ...

On the Shiftability of Dual-Tree Complex Wavelet Transforms

Michaël Unser, Kunal Narayan Chaudhury

The dual-tree complex wavelet transform (DT-ℂWT) is known to exhibit better shift-invariance than the conventional discrete wavelet transform. We propose an amplitude-phase representation of the DT-ℂWT which, among other things, offers a direct explanation ...

Field study of the dynamics and modelling of subgrid-scale turbulence in a stable atmospheric surface layer over a glacier

Wolf Hendrik Huwald, Marc Parlange, Charles Vivant Ignacio Meneveau, Chad Higgins

A field experiment – the Snow Horizontal Array Turbulence Study (SnoHATS) – has been performed over an extensive glacier in Switzerland in order to study small-scale turbulence in the stable atmospheric surface layer, and to investigate the role, dynamics ...
