Data-driven coarse graining in action: Modeling and prediction of complex systems

Sebastian Krumscheid, Grigorios A. Pavliotis

In many physical, technological, social, and economic applications, one is commonly faced with the task of estimating statistical properties, such as mean first passage times of a temporal continuous process, from empirical data (experimental observations) ...

In vivo evaluation of a novel 'diastole-patching' algorithm for the estimation of pulse transit time: advancing the precision in pulse wave velocity measurement

Nikolaos Stergiopoulos, Orestis Vardoulis

Carotid-to-femoral pulse wave velocity (PWV) is the gold standard for the assessment of aortic stiffness. It is calculated by the ratio of pulse transit time (PTT) between two arterial sites and the distance between them. The precision of PTT estimation de ...

Sparsity-Driven Statistical Inference for Inverse Problems

Ulugbek Kamilov

This thesis addresses statistical inference for the resolution of inverse problems. Our work is motivated by the recent trend whereby classical linear methods are being replaced by nonlinear alternatives that rely on the sparsity of naturally occurring sig ...

Looking for “frequent walkers” among the resident population of Switzerland

Vincent Kaufmann, Emmanuel Pierre Jean Ravalet, Derek Pierre Christie

Walking is the focus of increasing interest. However, the phenomenon of people who spontaneously walk great distances has not been investigated. Here, we analyse quantitative data from the Swiss transport micro-census (MRMT2010), containing information fro ...

Does an intraneural interface short-term implant for robotic hand control modulate sensorimotor cortical integration? An EEG-TMS co-registration study on a human amputee

Silvestro Micera, Leopoldo Rossini

Purpose: Following limb amputation, central and peripheral nervous system relays partially maintain their functions and can be exploited for interfacing prostheses. The aim of this study is to investigate, for the first time by means of an EEG-TMS co-regis ...

Inverse modeling of geochemical and mechanical compaction in sedimentary basins through Polynomial Chaos Expansion

Lorenzo Tamellini

We present an inverse modeling procedure for the estimation of model parameters of sedimentary basins subject to compaction driven by mechanical and geochemical processes. We consider a sandstone basin whose dynamics are governed by a set of unknown key qu ...

The performance test and analysis of the third and fourth China PF conductor for ITER

Pierluigi Bruzzone, Boris Stepanov, Bo Liu

The third Chinese PF conductor for ITER PF5 (PFCN3) and the fourth Chinese PF conductor for ITER PF2/3/4 (PFCN4) conductor in Phase II were manufactured in ASIPP and tested in the SULTAN facility. This paper introduces the PFCN3 and PFCN4 sample manufactur ...

Numerical investigation of particle-laden thermally driven turbulent flows in enclosure

Riccardo Puragliesi

Nowadays, the global increase of energy demand and the necessity to satisfy high safety standards have led engineers and scientists to focus their efforts in order to understand and describe fundamental phenomena that are crucial for a correct design of th ...

Markov Chain Modeling And Analysis Of Complicated Phenomena In Coupled Chaotic Oscillators

Martin Hasler

In this paper, we propose a Markov chain modeling of complicated phenomena observed from coupled chaotic oscillators. Once we obtain the transition probability matrix from computer simulation results, various statistical quantities can be easily calculated ...

Trajectory analysis using point distribution models

Pierre Roduit

This thesis focuses on the analysis of the trajectories of a mobile agent. It presents different techniques to acquire a quantitative measure of the difference between two trajectories or two trajectory datasets. A novel approach is presented here, based o ...
