In the last two decades, the level set method has been extensively used for the numerical solution of interface problems in different domains. The basic idea is to embed the interface as the level set of a regular function. In this paper we focus on the numerical solution of interface advection equations appearing in free-surface fluid dynamics problems,(More)
Researches on green data centers have defined guidelines and end-to-end methodologies to increase energy efficiency. Most of these approaches require a disrupting reengineering of the infrastructure and significant upfront investments. Smaller data centers need to reach green objectives with a more incremental approach. The EnergIT project proposes a(More)
The problem of link prediction has recently received increasing attention from scholars in network science. In social network analysis, one of its aims is to recover missing links, namely connections among actors which are likely to exist but have not been reported because data are incomplete or subject to various types of uncertainty. In the field of(More)
Ionic wind devices or electrostatic fluid accelerators are becoming of increasing interest as tools for thermal management, in particular for semiconductor devices. In this work, we present a numerical model for predicting the performance of such devices; its main benefit is the ability to accurately predict the amount of charge injected from the corona(More)
Benchmark configurations for quantitative validation and comparison of incompressible interfacial flow codes, which model two-dimensional bubbles rising in liquid columns, are proposed. The benchmark quantities: circularity, center of mass, and mean rise velocity are defined and measured to monitor convergence towards a reference solution. Initial studies(More)
Acknowledgements First of all, I would like to thank Prof. Alfio Quarteroni for having shared with me a piece of his infinite mathematical knowledge. His contribution does not limit to the mathematical level: I appreciated his patience and wisdom as well as his capacity to take the best out of me. I would like also to thank a lot Dr. Marco Discacciati for(More)
Fédérale de Lausanne. Working on this exciting project led to a lot of fruitful collaborations that I really appreciated and would like to acknowledge here. First of all, I would like to warmly thank Professor Florian Wurm for his guidance and very friendly and patient attitude towards my straight opinions. Many thanks for giving me the opportunity and(More)
