As part of studies that employ health electronic records databases, this paper advocates the employment of graph theory for investigating drug-switching behaviors. Unlike the shared approach in this field (comparing groups that have switched with control groups), network theory can provide information about actual switching behavior patterns. After a brief and simple introduction to...

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...

Smartphones have become a ubiquitous part of adolescents' life, and studies have repeatedly revealed a positive association between smartphone use (SU) and problematic smartphone use (PSU). However, longitudinal research investigating the reciprocal relationship among SU and PSU during adolescence are scarce, and studies that take into consideration personality traits as predisposing factors...

This thesis, ApprentIA, is an experimental thesis. The goal was to get a hang of the humanoid robot called NAO, to test the limits of coding implementations, and try to create an interaction between NAO and a student at the university level where the robot could help the student in his studies. The first part of this document is dedicated to humanoid robots to position NAO in the world of...

In this paper, we present the evolution of Swiss Media and Communication Studies over the last decade by summarizing the main results from a project funded by the Swiss University Conference (2008–2017). We give an overall picture of the growth in the field (in terms of student numbers, resources and activities), look at diversity in terms of topics (two clusters are identified and ...

The use of self-generated drawings has been found to be a powerful strategy for problem solving. However, many students do not engage in drawing activities. In this study, we investigated the effects of the enjoyment of the drawing strategy, anxiety about the drawing strategy, and prior intramathematical performance on the use of the drawing strategy and modelling performance. We explored the...

Switzerland is undergoing a curricular change. Curriculum 21 has been ratified by all 21 German-speaking and is currently being implemented. With this innovation, German-speaking Switzerland will move toward a more technology-oriented education. What has been Manual Training or Wood/ Metalwork Classes is now replaced by composite subjects such as Nature and Technology. These subjects now...

Programmable switches based on the Protocol Independent Switch Architecture (PISA) have greatly enhanced the flexibility of today's networks by allowing new packet protocols to be deployed without any hardware changes. They have also been instrumental in enabling a new computing paradigm in which parts of an application's logic run within the network core (in-network computing). The...
