Les matériaux dangereux dans les objets techniques cinématographiques

Lefebvre, Alexandra

Mémoire de bachelor : Haute Ecole Arc Conservation-Restauration, 2019.

Le Centre de recherche et d’archivage de la Cinémathèque suisse, à Penthaz, conserve une collection de 3000 objets techniques cinématographiques du XVIIIème siècle à nos jours. La problématique de ce mémoire traite des matériaux dangereux dans les objets techniques cinématographiques : amiante, mercure, biphényles polychlorés (PCB) et radioactivité. L’usage de ces matériaux aux...

Towards the democratization of ontological modeling through a new pervasive means of representation

Baset, Selena ; Stoffel, Kilian (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019 ; 2787.

Despite their proven utility in various areas of knowledge engineering, ontologies are falling short of reaching an equal position as formal domain models in the landscape of enterprise software development. With the ultimate goal of making ontologies more accessible to a wider audience of software development stakeholders, this thesis investigates the reasons that are still standing between...

Nodesketch: highly-efficient graph embeddings via recursive sketching

Yang, Dingqi ; Rosso, Paolo ; Li, Bin ; Cudre-Mauroux, Philippe

In: Proceedings of the 25th ACM SIGKDD International Conference on Knowledge Discovery & Data Mining, 2019, p. 1162–1172

Embeddings have become a key paradigm to learn graph representations and facilitate downstream graph analysis tasks. Existing graph embedding techniques either sample a large number of node pairs from a graph to learn node embeddings via stochastic optimization, or factorize a high-order proximity/adjacency matrix of the graph via expensive matrix factorization. However, these techniques...

New frontiers of ultrafast thin-disk laser oscillators for applications in metrology and the generation of THz and XUV radiation

Modsching, Norbert Paul ; Südmeyer, Thomas (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Ultrafast laser systems find application as versatile tool in industry and science. Ultrafast laser systems based on Ti:sapphire – the workhorse in ultrafast science – operate typically at kHz repetition rates and benefit from the available broad gain bandwidth for the direct generation of sub 100-fs pulse durations. However, thermal effects in the gain medium due to a high quantum defect...

Scalable content-based publish/suscribe and application to online trading

Barazzutti, Raphaël P. ; Felber, Pascal (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Publish/subscribe is a popular messaging pattern that provides efficient and decoupled information dissemination in distributed environments. Publishers generate a flow of information as publications, which are routed to subscribers based on their interests expressed as subscriptions. Matching events against filters has a non-negligible processing cost. Our first contribution within this...

Hitting the right spot : mechanism of action of OPB‐31121, a novel and potent inhibitor of the Signal Transducer and Activator of Transcription 3 (STAT3)

Brambilla, Lara ; Genini, Davide ; Laurini, Erik ; Merulla, Jessica ; Perez, Laurent ; Fermeglia, Maurizio ; Carbone, Giuseppina M. ; Pricl, Sabrina ; Catapano, Carlo V.

In: Molecular oncology, 2015, vol. 9, no. 6, p. 1194-1206

STAT3 is a key element in many oncogenic pathways and, like other transcription factors, is an attractive target for development of novel anticancer drugs. However, interfering with STAT3 functions has been a difficult task and very few small molecule inhibitors have made their way to the clinic. OPB‐31121, an anticancer compound currently in clinical trials, has been reported to affect...

On the many faces of atomic multicast

Coelho, Paulo ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO004.

Many current online services need to serve clients distributed across geographic areas. Coordinating highly available and scalable geographically distributed replicas, however, is challenging. While State Machine Replication is the most direct way of achieving availability, no scalability comes from the traditional approach. Typically, scalability is obtained by partitioning the original...

Fast and automatic assessment of fall risk by coupling machine learning algorithms with a depth camera to monitor simple balance tasks

Dubois, Amandine ; Mouthon, Audrey ; Sivagnanaselvam, Ranjith Steve ; Bresciani, Jean-Pierre

In: Journal of NeuroEngineering and Rehabilitation, 2019, vol. 16, no. 1, p. 71

Falls in the elderly constitute a major health issue associated to population ageing. Current clinical tests evaluating fall risk mostly consist in assessing balance abilities. The devices used for these tests can be expensive or inconvenient to set up. We investigated whether, how and to which extent fall risk could be assessed using a low cost ambient sensor to monitor balance tasks.Method:...

Three essays in labor economics

Gentili, Elena ; Mazzonna, Fabrizio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019ECO003.

In this thesis, I investigate two of the main challenges faced by developed societies: aging and migration. In the first chapter, I consider the cultural determinants of elderly care arrangement decisions. The empirical strategy focuses on the three German and French speaking Swiss bilingual cantons. Particularly, since the structure of long-term care provision is planned at cantonal level, I...
