Cell mechanics in flow : algorithms and applications

Lykov, Kirill ; Pivkin, Igor V. (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO008.

The computer simulations are pervasively used to improve the knowledge about biophysical phenomena and to quantify effects which are difficult to study experimentally. Generally, the numerical methods and models are desired to be as accurate as possible on the chosen length and time scales, but, at the same time, affordable in terms of computations. Until recently, the cell mechanics and blood...

Theory and applications of bijective barycentric mappings

Schneider, Teseo ; Hormann, Kai (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO007.

Barycentric coordinates provide a convenient way to represent a point inside a triangle as a convex combination of the triangle's vertices, and to linearly interpolate data given at these vertices. Due to their favourable properties, they are commonly applied in geometric modelling, finite element methods, computer graphics, and many other fields. In some of these applications it is desirable...

Abandon ship? : party brands and politicians’ responses to a political scandal

Daniele, Gianmarco ; Galletta, Sergio ; Geys, Benny

In this article, we study politicians’ – rather than voters’ – responses to the main political scandal in Italian recent history (Tangentopoli), and overcome endogeneity concerns by analysing the local implications of this national corruption scandal. We find that local politicians withdraw support for incumbents in parties hit by Tangentopoli – inducing increased political...

Geometry–aware finite element framework for multi–physics simulations : an algorithmic and software-centric perspective

Zulian, Patrick ; Krause, Rolf (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO006.

In finite element simulations, the handling of geometrical objects and their discrete representation is a critical aspect in both serial and parallel scientific software environments. The development of codes targeting such envinronments is subject to great development effort and man-hours invested. In this thesis we approach these issues from three fronts. First, stable and efficient ...

Beyond the knowledge gap paradigm : the role of psychological empowerment in parents’ vaccination decision

Fadda, Marta ; Schulz, Peter J. (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017COM008.

Even though the efficacy and safety of immunization have been widely proven (Plotkin, 2014), an increasing number of parents have refused to vaccinate their children against serious infectious diseases in the past twenty years (Dubé, Gagnon, Nickels, Jeram, & Schuster, 2014). A recent shift in the study of vaccination decision- making has seen scholars moving beyond the idea that mere lack of...

Analysis and new constructions of generalized barycentric coordinates in 2D

Anisimov, Dmitry ; Hormann, Kai (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO004.

Different coordinate systems allow to uniquely determine the position of a geometric element in space. In this dissertation, we consider a coordinate system that lets us determine the position of a two-dimensional point in the plane with respect to an arbitrary simple polygon. Coordinates of this system are called generalized barycentric coordinates in 2D and are widely used in computer...

Holistic recommender systems for software engineering

Ponzanelli, Luca ; Lanza, Michele (Dir.) ; Mocci, Andrea (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO005.

The knowledge possessed by developers is often not sufficient to overcome a programming problem. Short of talking to teammates, when available, developers often gather additional knowledge from development artifacts (e.g., project documentation), as well as online resources. The web has become an essential component in the modern developer’s daily life, providing a plethora of information ...

Capolavori in miniatura : Pier Luigi Nervi e la modellazione strutturale

Neri, Gabriele

Mendrisio ; Cinisello Balsamo : Mendrisio Academy Press ; Silvana Editoriale, 2014

(ISA, Istituto di storia e teoria dell'arte e dell'architettura)

ISBN: 9788836627233

Nel corso della sua carriera Pier Luigi Nervi (1891-1979), l’ingegnere italiano più famoso del Novecento, utilizzò spesso il modello in scala ridotta per studiare le sue complesse strutture in cemento armato: dalle Aviorimesse di Orvieto al Grattacielo Pirelli, dalla Torre della Borsa di Montreal alla Cattedrale di San Francisco. Questi modelli erano molto particolari: grazie alla...

What drives the substitutability between native and foreign workers? : evidence about the role of language

Gentili, Elena ; Mazzonna, Fabrizio

This paper investigates the role of language in determining the degree of substitutability between foreign and native workers. To this end, we focus on Switzerland, an immigration-receiving country with four official languages spoken, three of which in common with bordering countries. We modify the model proposed by Ottaviano and Peri (2012) to account for the linguistic background of native...

Observable dynamic compilation

Zheng, Yudi ; Binder, Walter (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO003.

Managed language platforms such as the Java Virtual Machine rely on a dynamic compiler to achieve high performance. Despite the benefits that dynamic compilation provides, it also introduces some challenges to program profiling. Firstly, profilers based on bytecode instrumentation may yield wrong results in the presence of an optimizing dynamic compiler, either due to not being aware of...
