Track: GW detection
In this lecture I give an overview of the gravitational-wave experiment and methods used in the analysis of data from the ground-base detectors. The purpose of the lecture is to describe how a worldwide network of GW detectors works, with focus on signal processing techniques and reconstruction methods, rather than to describe details of specific search algorithms used so far in the GW ...

Track: bayesian inference
A classical problem in synchronization, an activity that plays a central role in signal processing for digital communication, is that of extracting the phase of a sinusoid affected by phase noise and embedded in additive noise. In the talk, the problem is presented as an instance of Bayesian inference. Four variants of the basic problem are treated. 1) Sinusoid with constant amplitude, where the ... More

Track: neuroimaging
In the framework of neurodegenerative diseases, and in particular the Alzheimer's disease (AD), we are witnessing an increasing presence of neuroimaging data, magnetic resonant images (MRI) and positron emission tomography (PET) above all. Despite the fact that clinical scanners have been around for some decades, MRI and PET images have only recently become a dependable support in diagnosing earl ... More

Track: bayesian inference
Given a hidden state process with memory and a measurement process that is memoryless given the state, one has to make inference on the hidden state sequence given the measurement sequence. This activity can be performed by the so-called Bayesian tracking, where the probability of the state at time k is recursively computed from the probability of the state at time k-1 and from the measurement at ...

Track: radar clutter
The first part of the talk focuses on the statistical analysis and modeling of radar clutter echoes. This is a central issue for the design and performance evaluation of radar systems. Main goal of this talk is to describe the state-of-the-art approaches to the modeling and understanding of land and sea clutter echoes and their implications on performance prediction and signal processors design. ...

Track: Coherent target detection
Coherent radar target detection is the subject of the second part of the talk. In high resolution radar systems the disturbance cannot be modelled as Gaussian distributed and the classical detectors suffer from high losses. Then, according to the adopted disturbance model, optimum and sub-optimum detectors are derived and their performance analyzed against a non-Gaussian background. First, the pro ... More

Track: GPU
With the advance of cheaply available many-core architectures (such as GPU-s) on the computing market scientific computing entered into a new era. There are plenty of mathematical algorithms and data analysis methods which can be easily, massively parallelized and implemented on these architectures resulting a dramatic increase of speed (several order of magnitude) and - at the same time - d ...
