Learning dynamical systems using dynamical systems : the reservoir computing approach

Verzelli, Pietro ; Alippi, Cesare (Dir.) ; Livi, Lorenzo (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2022 ; 2022INF001.

Dynamical systems have been used to describe a vast range of phenomena, including physical sciences, biology, neurosciences, and economics just to name a few. The development of a mathematical theory for dynamical systems allowed researchers to create precise models of many phenomena, predicting their behaviors with great accuracy. For many challenges of dynamical systems, highly accurate...

Teaching architecture : Peter Zumthor and the foundations of composition

De Conti Lorentz, Rafael ; Angonese, Walter (Dir.) ; Rakowitz, Gundula (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021ARC003.

In 1996, the newly founded Academy of Architecture of Mendrisio invited Peter Zumthor to be the professor in charge of one of the school’s first three design studios. What took form from that was a singular educational experience, conducted by Zumthor as a didactic project spanning a three-year period - the academic years of 1996-97, 1997-98 and 1998-99 - and comprehending a sequence of 19...

Graph neural networks : operators and architectures

Grattarola, Daniele ; Alippi, Cesare (Dir.) ; Livi, Lorenzo (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO014.

This thesis explores the field of graph neural networks, a class of deep learning models designed to learn representations of graphs. We organise the work into two parts. In the first part, we focus on the essential building blocks of graph neural networks. We present three novel operators for learning graph representations: one graph convolutional layer and two methods for pooling. We put...

The ultrasound risk stratification systems for thyroid nodule have been evaluated against papillary carcinoma : a meta-analysis

Trimboli, Pierpaolo ; Castellana, Marco ; Piccardo, Arnoldo ; Romanelli, Francesco ; Grani, Giorgio ; Giovanella, Luca ; Durante, Cosimo

In: Reviews in endocrine and metabolic disorders, 2020, p. 8 p

Thyroid imaging reporting and data systems (TIRADS) are used to stratify the malignancy risk of thyroid nodule by ultrasound (US) examination. We conducted a meta-analysis to evaluate the pooled cancer prevalence and the relative prevalence of papillary, medullary, follicular thyroid cancer (PTC, MTC, and FTC) and other malignancies among nodules included in studies evaluating their...

Analyzing cultural tourism promotion on Instagram : a cross-cultural perspective

Mele, Emanuele ; Kerkhof, Peter ; Cantoni, Lorenzo

In: Journal of travel & tourism marketing, 2021, vol. 38, no. 3, p. 326-340

A lack of cross-cultural research has been identified regarding cultural tourism promotion on social media. Using the dimensions of Collectivism-Individualism, Power Distance, and High-Context vs. Low-Context communication, we content analyze cultural value differences in Instagram posts promoting cultural tourism – published by the national tourism organizations of Chile, Portugal, USA, and...

Multigrid methods for fractional diffusion equations

Trotti, Ken ; Krause, Rolf (Dir.) ; Donatelli, Marco (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO013.

Recent years have seen the rapid growth in interest towards fractional calculus. Fractional calculus plays an important role in modelling anomalous diffusion phenomena, however closed-form analytical solutions of such equations are rarely available, hence numerical estimates are needed. In this thesis we consider various fractional diffusion equations (FDEs), where different fractional ...

Mining code change patterns to aid software development

Fengcai, Wen ; Bavota, Gabriele (Dir.) ; Lanza, Michele (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO012.

Mining Software Repositories (MSR) has become a complete and mature research field, also due to the increasing number of open source projects publicly available. Repository hosting services such as GitHub provide unprecedented access to millions of events generated during development activities (e.g., code commits, pull requests), that can be mined and analyzed to extract new pieces of...

Les fonds ISR Swiss Made

Alves De Freitas, Dany ; Sonney, Frédéric (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2021 ; TDEE 447.

La finance durable est une norme qui s’impose dans le domaine financier. Désormais, il est inutile de lancer un fonds de placement qui n’a pas d’objectif de durabilité. Toutefois, pour un investisseur, il n’est pas toujours facile de comprendre en quoi son investissement est bénéfique pour la planète et ses habitants. Les gérants ne sont pas toujours transparents et certains...

Efficience des marchés financiers : analyse empirique sur le marché suisse

Chuard, David ; Seiler, Robert (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2021 ; TDEE 448.

Après 50 ans de recherches scientifiques et controverses, la théorie de l’efficience des marchés financiers demeure un concept central de la formation et fluctuation des prix. Malgré les débats entre les partisans de la finance classique et comportementale, le consensus académique n’a pu aboutir à un modèle permettant de se substituer à celui de l’efficience. Ce travail de...
