Physiologically responsive mechanically adaptive polymeric materials for biomedical applications

Jorfi, Mehdi ; Weder, Christophe (Dir.)

Thèse de doctorat : Université de Fribourg, 2014.

Künstliche neurale Schnittstellen können verwendet werden, um das zentrale Nervensystem mit der äusseren Welt zu verbinden. Sie bieten deshalb grosses Potential für die Rehabilitierung von Patienten, die unter Lähmung, anderen Formen von motorischer Dysfunktion oder Amputationen leiden. Es wurden verschiedene Arten neuraler Gehirnschnittstellen entwickelt, mit unterschiedlichen...

The irony of networks

Markovic, Josip ; Cristofoli, Daniela (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2015 ; 2015ECO002.

By the end of the 1970s, it became evident that hierarchies were not always the most efficient and effective solution for complex problems in increasingly plural and fragmented societies.

The concept of extreme events describes the above average behavior of a process, for instance, heat waves in climate or weather research, earthquakes in geology and financial crashes in economics. It is significant to study the behavior of extremes, in order to reduce their negative impacts. Key objectives include the identification of the appropriate mathematical/statistical model, description...

Slowness learning for curiosity-driven agents

Kompella, Varun Raj ; Schmidhuber, Jürgen (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2014 ; 2014INFO013.

In the absence of external guidance, how can a robot learn to map the many raw pixels of high-dimensional visual inputs to useful action sequences? I study methods that achieve this by making robots self-motivated (curious) to continually build compact representations of sensory inputs that encode different aspects of the changing environment. Previous curiosity-based agents acquired skills by...
