Writing in finance : improving the communicative potential of financial analysts' recommendations

Whitehouse, Marlies ; Rocci, Andrea (Dir.) ; Perrin, Daniel (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2022 ; 2022COM001.

This doctoral thesis identifies and analyses problems of text production in finance from three complementary perspectives and explains why solving these problems benefits theory, practice, and society at large. Part I, Problem Identification, outlines the current situation of writing in finance, its problems and their consequences on the financial community and on society at large, entailing...

Detecting Alzheimer’s disease (AD) : from the asymptomatic stages of healthy adults with AD genetic disposition to late stages of severe neurocognitive impairment

Ibnidris, Aliaa ; Albanese, Emiliano (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021BIOMED001.

Background: Dementia is a syndrome characterized by progressive cognitive impairment, psychological and behavioural symptoms, and functional deficits. It is one of the leading causes of disability worldwide; its impact and the associated costs are enormous. Consequently, dementia is a global public health priority, and so is Alzheimer’s disease (AD), the most common cause of dementia in late...

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...

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...

Without a plan? : an ethnography of architecture, domestic microclimates, and building practices in contemporary Cairo

Ghodbane, Dalila ; Roesler, Sascha (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2021ARC002.

This study is located at the intersection of architecture and the social sciences. Its core is an ethnographic investigation of how Cairo experiences and tackles urban heatwaves, which was carried out primarily by looking at people’s building practices. The research is structured along three axes. The first consists of a historical overview of the Egyptian architectural field, based on a...

Sensor-based recognition of engagement during work and learning activities

Di Lascio, Elena ; Santini, Silvia (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO011.

Personal computing systems like e.g., laptop, smartphone, and smartwatches are nowadays ubiquitous in people's everyday life. People use such systems not only for communicating or searching for information, but also as digital companions, able to track and support their daily activities such as sleep, food intake, physical exercise and even work. Sensors embedded in personal computing systems...

Agents in superposition

Baumann, Veronika ; Brukner, Caslav (Dir.) ; Wolf, Stefan (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO010.

The idea of agents in superposition is central to both encapsulated observers, i.e. Wigner’s-friend-type experiments, and correlations without definite causal order. An agent might be regarded as a thinking or computing entity that is able to perform operations on (other) quantum systems. In case of Wigner’s-friend setups, an agent’s ability to make predictions about other agents...
