A Geometric Approach to Poincaré Inequality and Minkowski Content of Separating Sets

The goal of this paper is to continue the study of the relation between the Poincar & eacute; inequality and the lower bounds of Minkowski content of separating sets, initiated in our previous work [5]. A new shorter proof is provided. It is based on the s ...

Separation of kinetic rate orders in extreme ultraviolet transient grating spectroscopy

Majed Chergui, Giulia Fulvia Mancini, Michele Puppin, Oliviero Cannelli, Camila Bacellar Cases Da Silveira, Serhii Polishchuk, Rebecca Ann Ingle, Hugo Jean Baptiste Marroux

We present an extreme ultraviolet (EUV) transient grating (TG) experiment of the spinel Co3O4 compound using tuneable incident energies across the Co M-2,M-3-edge and a 395 nm probe pulse, detecting both the first and the second diffraction orders (SDOs). ...

Frequency-Domain Diffusion Adaptation Over Networks

Ali H. Sayed

This paper analyzes the implementation of least-mean-squares (LMS)-based, adaptive diffusion algorithms over networks in the frequency-domain (FD). We focus on a scenario of noisy links and include a moving-average step for denoising after self-learning to ...

Graph-based regularization of inverse problems in imaging

Mattia Rossi

As of today, the extension of the human visual capabilities to machines remains both a cornerstone and an open challenge in the attempt to develop intelligent systems. On the one hand, the development of more and more sophisticated imaging devices, capable ...

Interior Tomography Using 1D Generalized Total Variation. Part I: Mathematical Foundation

Michaël Unser, John Paul Ward

Motivated by the interior tomography problem, we propose a method for exact reconstruction of a region of interest of a function from its local Radon transform in any number of dimensions. Our aim is to verify the feasibility of a one-dimensional reconstru ...

An optimally concentrated Gabor transform for localized time-frequency components

Benjamin Ricaud

Gabor analysis is one of the most common instances of time-frequency signal analysis. Choosing a suitable window for the Gabor transform of a signal is often a challenge for practical applications, in particular in audio signal processing. Many time-freque ...

Application of vertex and mass constraints in track-based alignment

Olivier Schneider, Maurizio Martinelli, Frédéric Guillaume Dupertuis, Christophe Salzmann, Vincent Fave

The software alignment of planar tracking detectors using samples of charged particle trajectories may lead to global detector distortions that affect vertex and momentum resolution. We present an alignment procedure that constrains such distortions by mak ...

Empirical Study of Noise Dependence in Electrochemical Sensors

Giovanni De Micheli, Sandro Carrara, Seyedeh Sara Ghoreishizadeh

We report the experimental study of noise in electrochemical biosensors as related to voltage and concentration. A comparison with experiments is performed for H2O2 and Ferrocyanide with bare sensors and with sensors functionalized wi ...
