ELearning acceptance in hospitals : continuing medical education of healthcare professionals

Bachmann, Larissa ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2009.

ELearning provides healthcare professionals an interesting alternative of participating to Continuing Medical Education (CME) activities. It offers the possibility to attend courses at a distance, and it allows creating personal learning schedules without needing to leave the job or the family. Hospitals can choose to organize CME activities for their employees and therefore may also opt to...

High energy resolution off-resonant X-ray spectroscopy

Błachucki, Wojciech ; Hoszowska, Joanna (Dir.)

Thèse de doctorat : Université de Fribourg, 2015 ; no. 1932.

Ce travail de thèse est consacré à la méthode HEROS (spectroscopie X hors-résonance en haute résolution), une méthode permettant d’étudier les niveaux électroniques inoccupés dans le voisinage des bords d’absorption. La méthode HEROS qui représente une alternative aux méthodes d’absorption XAS traditionnelles ouvre la voie à de nouvelles investigations irréalisables...

Two non-destructive neutron inspection techniques : prompt gamma-ray activation analysis and cold neutron tomography

Baechler, Sébastien ; Dousse, Jean-Claude (Dir.) ; Jolie, Jan (Codir.)

Thèse de doctorat : Université de Fribourg, 2002 ; no 1381.

Deux techniques d’inspection non-destructives utilisant des faisceaux de neutrons froids ont été développées à la source de neutrons SINQ de l’Institut Paul Scherrer : (1) l’analyse par activation neutronique prompte (PGAA) et (2) la tomographie neutronique. L’analyse par PGA (Prompt Gamma-ray Activation) est une méthode nucléaire qui permet de déterminer la concentration...

Just-in-time information retrieval and summarization for personal assistance

Bahrainian, Seyed Ali ; Crestani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO014.

With the rapid development of means for producing user-generated data opportunities for collecting such data over a time-line and utilizing it for various human-aid applications are more than ever. Wearable and mobile data capture devices as well as many online data channels such as search engines are all examples of means of user data collection. Such user data could be utilized to model user...

The futures price volatility in the crude oil market

Bakanova, Asyl ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2011 ; 2011ECO010.

The main goal of this thesis is to present and evaluate different procedures for modeling and forecasting volatility, and examine the relative accuracy of these forecasts using data from the light, sweet crude oil futures market traded at New York Mercantile Exchange (NYMEX). First, we consider various volatility models and find that the models, which account for long memory, has the best...

Optimization of anchor nodes placement in wireless localization networks

Balac, Katarina ; Malek, Miroslaw (Dir.) ; Prevostini, Mauro (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO009.

This work focuses on optimizing node placement for time-of-flight-based wireless localization networks. Main motivation are critical safety applications. The first part of my thesis is an experimental study on in-tunnel vehicle localization. In- tunnel localization of vehicles is crucial for emergency management, especially for large trucks transporting dangerous goods such as inflammable...

Test generation for high coverage with abstraction refinement and coarsening (ARC)

Baluda, Mauro ; Pezzè, Mauro (Dir.) ; Denaro, Giovanni (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2014 ; 2014INFO018.

Testing is the main approach used in the software industry to expose failures. Producing thorough test suites is an expensive and error prone task that can greatly benefit from automation. Two challenging problems in test automation are generating test input and evaluating the adequacy of test suites: the first amounts to producing a set of test cases that accurately represent the software...

Content-based image retrieval using hand-drawn sketches and local features : a study on visual dissimilarity

Banfi, Folco ; Ingold, Rolf (Dir.)

Thèse de doctorat : Université de Fribourg : 2000 ; no 1312.

Cette thèse traite la problématique de la recherche d’images par rapport au contenu (content-based image retrieval, abrégé CBIR, en anglais) dans une base de données hétérogène. Dans une analyse faite au début de ce travail, nous avons montré que des améliorations étaient possibles dans trois secteurs de cette branche: la forme de la requête, la représentation des images et des...
