Accommodation of NLOS for Ultra-Wideband TDOA Localization in Single- and Multi-Robot Systems

Phillip Tomé, Amanda Stella Markowska Prorok

Ultra-wideband (UWB) localization is one of the most promising indoor localization methods. Yet, non-line-ofsight (NLOS) positioning scenarios remain a challenge and can potentially cause significant localization errors. In this work, we leverage the utili ...

Measuring amplitude and phase of light emerging from microstructures with HRIM

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

Ultra high-resolution measurements of amplitude and phase fields emerging from fine period amplitude gratings are presented and discussed. In the axial direction periodically repeated features are found, whose origins are the Talbot effect within the Fresn ...

Direct-Ambient Decomposition and Upmix of Surround Signals

Christof Faller, Andreas Walther

Various direct-ambient signal decompositions, applicable to two-channel stereophonic signals, have been proposed previously. Strategies to enhance these decompositions for multi-channel surround audio signals are not obvious. A method is proposed, which es ...

Diffusion Strategies for Distributed Kalman Filtering and Smoothing

Ali H. Sayed

We study the problem of distributed Kalman filtering and smoothing, where a set of nodes is required to estimate the state of a linear dynamic system from in a collaborative manner. Our focus is on diffusion strategies, where nodes communicate with their d ...

Distributed nonlinear Kalman filtering with applications to wireless localization

Ali H. Sayed

We study the problem of distributed state-space estimation, where a set of nodes are required to estimate the state of a nonlinear state-space system based on their observations. We extend our previous work on distributed Kalman filtering to the nonlinear ...

Simultaneous Pose, Correspondence and Non-Rigid Shape

Pascal Fua, Jonas Olof Martin Östlund

Recent works have shown that 3D shape of non-rigid surfaces can be accurately retrieved from a single im- age given a set of 3D-to-2D correspondences between that image and another one for which the shape is known. However, existing approaches assume that ...

Grid Filter Modeling for Large-Eddy Simulation

Michel Deville, Marc Anthony David Habisreutinger, Roland Bouffanais

An interpretation to the use of deconvolution models when used in implicitly filtered large-eddy simulations as a way to approximate the projective grid filter is given. Consequently, a new category of subgrid models, the grid filter models, is defined. Th ...

Design and characterization of low aspectratio nanopore arrays

Laurent Coulot

Alumina nanopores seem to be very promising concerning many applications, such as DNA analysis 1‐2, separation of molecules 3‐4 or fabrication of nanopillars 5‐6. The nanopores are made by anodization, which is a really simple fabrication process requiring ...

Double Sparsity: Towards Blind Estimation of Multiple Channels

Rémi Gribonval

We propose a framework for blind multiple filter estimation from convolutive mixtures, exploiting the time-domain sparsity of the mixing filters and the disjointness of the sources in the time-frequency domain. The proposed framework includes two steps: (a ...

A power-efficient, current-mode, binary-tree min / max circuit for Kohonen self-organizing feature maps and nonlinear filters

Rafal Tomasz Dlugosz

A novel current-mode, binary-tree Min / Max circuit for application in analog neural networks and filters has been presented. In the proposed circuit input currents are first converted to step signals with equal amplitudes and different delays that are pro ...
