Modelling protein-protein interactions to elucidate molecular mechanisms behind neurodegenerative diseases

Grasso, Gianvito ; Krause, Rolf (Dir.) ; Danani, Andrea (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO017.

The worldwide significant increase in life expectancy has recently drawn the attention of the scientific community to neurodegenerative pathologies of the elderly population. These neurodegenerative disorders arise from the abnormal protein aggregation in the nervous tissue leading to intracellular inclusions or extracellular aggregates in specific brain areas. A feasible strategy to prevent...

Exposing concurrency failures : a comprehensive survey of the state of the art and a novel approach to reproduce field failures

Bianchi, Francesco Adalberto ; Pezzè, Mauro (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO015.

With the rapid advance of multi-core and distributed architectures, concurrent systems are becoming more and more popular. Concurrent systems are extremely hard to develop and validate, as their overall behavior depends on the non-deterministic interleaving of the execution flows that comprise the system. Wrong and unexpected interleavings may lead to concurrency faults that are extremely...

Reification as the key to augmenting software development : an object is worth a thousand words

Dal Sasso, Tommaso ; Lanza, Michele (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO014.

Software development has become more and more pervasive, with influence in almost every human activity. To be able to fit in so many different scenarios and constantly implement new features, software developers adopted methodologies with tight development cycles, sometimes with more than one release per day. With the constant growth of modern software projects and the consequent expansion...

Multimodal information retrieval

Geiger, Melanie ; Savoy, Jacques (Dir.) ; Braschler, Martin (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Les processus basés sur le savoir, une des composantes essentielles de notre économie, requiert souvent un système multimodal de recherche d’information. De tels systèmes doivent traiter des collections de documents et des requêtes de plus en plus complexes. Cette complexité sous-jacente se situe dans le grand nombre et la diversité des modalités textuelles ou non-textuelles comme les...

ASQ : active learning with interactive web presentations and classroom analytics

Triglianos, Vasileios ; Pautasso, Cesare (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO013.

Today it is commonly accepted that the effectiveness of instructional technology, measured as improvement over the learning outcomes of students, is highly correlated with the learning environment, the applied pedagogies and the goals of the participants of the learning process. The often applied passive lecture model and the undirected use of modern technology such as student laptops and...

Practical erasure codes for storage systems : the study of entanglement codes, an approach that propagates redundancy to increase reliability and performance

Estrada Galiñanes, Verónica del Carmen ; Felber, Pascal (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Cette dissertation traite de la conception de codes d'effacement pratiques pour les systèmes de stockage. Les défaillances de disque physiques et logiques sont une source commune d'erreurs; cependant, il est prédit que les disques dur à plateaux vont rester le support de stockage standard dans les grands centres de données. Le stockage dans le cloud a besoin de codes efficaces pour devenir...
