Performance bound for robust array calibration in radio interferometry

Robust calibration of next-generation radio-interferometers, as the square kilometer array (SKA) for instance, is a crucial prepro-cessing step for sky imaging. Recently, several robust calibration es-timators based on the use of well known strong…

Wide baseline pose estimation from video with a density-based uncertainty model

Robust wide baseline pose estimation is an essential step in the deployment of smart camera networks. In this work, we highlight some current limitations of conventional strategies for relative pose estimation in difficult urban scenes. Then, we…

Integrating Visual and Geometric Consistency for Pose Estimation

In this work, we tackle the problem of estimating the relative pose between two cameras in urban environments in the presence of additional information provided by low quality localization and orientation sensors. An M-estimator based approach…

Modified Sparse Subspace Clustering for Radar Detection in Non-stationary Clutter

Detecting targets embedded in a noisy environment is an important topic in adaptive array processing. In the traditional statistical framework, this problem is addressed through a binary hypothesis test, which usually requires the estimation of side…

Effects of mechanical compression on the performance of Polymer Electrolyte Fuel Cells and analysis through in-situ characterisation techniques - A review

One of the factors that affect the polymer electrolyte fuel cell (PEFC) performance is the mechanical compression inside the stack. Although this compression plays an important role to ensure efficient gas sealing along with optimised electrical and…
