Numerical simulations and uncertainty analysis for assessing spatial and temporal dynamics in alluvial river-aquifer systems : an application in the context of the 3rd Rhône River Correction

Gianni, Guillaume ; Brunner, Philip (Dir.) ; Perrochet, Pierre (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Characterizing river-groundwater interactions in alluvial aquifers is essential when forecasting the impact of river management strategies, such as river restorations, on the overall water resources distribution and dynamics. Therefore, the development of methods and calibration approaches that allow for better identification of the spatial and temporal characteristics of the hydraulic properties...

New architectures for very deep learning

Srivastava, Rupesh Kumar ; Schmidhuber, Jürgen (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO006.

Artificial Neural Networks are increasingly being used in complex real- world applications because many-layered (i.e., deep) architectures can now be trained on large quantities of data. However, training even deeper, and therefore more powerful networks, has hit a barrier due to fundamental limitations in the design of existing networks. This thesis develops new architectures that, for the...

Efficient memory management with hardware transactional memory : a focus on Java garbage collectors and C++ smart pointers

Carpen-Amarie, Maria ; Felber, Pascal (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

With multi-core systems becoming ubiquitous in the last few years, lightweight synchronization and efficient automatic memory management are more and more demanded in the design of applications and libraries. Memory management techniques try to take advantage of the growing parallelism as much as possible, but the increasingly complex synchronization introduces considerable performance issues....

The role of context in human memory augmentation

Niforatos, Evangelos ; Langheinrich, Marc (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO005.

Technology has always had a direct impact on what humans remember. In the era of smartphones and wearable devices, people easily capture on a daily basis information and videos, which can help them remember past experiences and attained knowledge, or simply evoke memories for reminiscing. The increasing use of such ubiquitous devices and technologies produces a sheer volume of pictures and...

Corporate governance issues and performance of initial public offerings

Seistrajkova, Biljana ; Nowak, Eric (Dir.) ; Degeorge, François (Codir.) ; Habib, Michel (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO005.

In my PhD thesis I analyze corporate governance issues of initial public offerings and their subsequent performance. In the first chapter I find that the first-day return of newly issued subsidiary stocks (equity carve-outs) is explained by the reporting distortions in the pre-IPO period, conditioned on whether the executives and directors of the subsidiary received stock options with an...

Understanding the effects of communication and engagement in a social marketing intervention on children’s eating behavior : design, measurement and evaluation

Rangelov, Natalie ; Suggs, Suzanne (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017COM014.

The prevalence of overweight and obesity represents a serious health problem, and is a risk factor for several non- communicable diseases. Poor nutrition and lack of regular physical activity are among the primary determinants of overweight and obesity. Data show that overweight and obesity rates are high in, and that the Swiss population does not adhere to the nutritional guidelines provided...

Beschäftigungsdynamik und Arbeitslosigkeit in der Schweiz zwischen 1990 und 2015 : wirtschaftsgeschichtliche Hintergründe, theoretische Grundlagen, empirische Bezüge und eine sozioökonomische Analyse der Arbeitslosigkeit

Bauer, Thomas ; Bortis, Heinrich (Dir.)

Thèse de doctorat : Université de Fribourg, 2017.

Angesichts einer grundlegenden weltwirtschaftlichen Krise, deren Ende bis heute nicht absehbar ist, war ich als Ökonom nach Studienabschluss gegenüber dieser Wirklichkeit weitgehend sprachlos geblieben. Ich hatte nicht das Gefühl, das richtige Rüstzeug erworben zu haben, welches mir ein grundlegendes Verständnis der wirtschaftlichen Verhältnisse ermöglichen sollte. Die neoklassische...

Automating test oracles generation

Goffi, Alberto ; Pezzè, Mauro (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO004.

Software systems play a more and more important role in our everyday life. Many relevant human activities nowadays involve the execution of a piece of software. Software has to be reliable to deliver the expected behavior, and assessing the quality of software is of primary importance to reduce the risk of runtime errors. Software testing is the most common quality assessing technique for...
