Negrini, Michela ; Paolini, Paolo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2014 ; 2014COM013.

Over the last decade, there has been an increasing number of technologies and devices (including smartphones, tablets and alike) able to provide new perspectives for the use of multimedia applications in the field of Cultural Heritage. This work arises from the interest in providing better authoring/delivery possibilities to cultural heritage institutions (small and medium sized in particular). ...

20th century minimum and maximum temperature variations analysed on a regional scale in Switzerland : statistical analyses of observational data

Jungo, Patricia ; Beniston, Martin (Dir.) ; Collet, Claude (Codir.) ; Frei, Christoph (Codir.) ; Wanner, Heinz (Codir.)

Thèse de doctorat : Université de Fribourg, 2001 ; no 1365.

The major aim of this study is to describe in a detailed manner the 20th century minimum and maximum temperature variations in Switzerland and to assess whether the magnitude of the secular warming and its interannual to interdecadal fluctuations show common seasonal patterns in different climatological regions. In a first step different climatological regions could successfully be...

2(CREM) : une méthode de reconnaissance structurelle de documents complexes basée sur des patterns bidimensionnels

Robadey, Lyse ; Ingold, Rolf (Dir.) ; Bapst, Frédéric (Codir.)

Thèse de doctorat : Université de Fribourg : 2001 ; No 1364.

This thesis addresses the question of printed document recognition. We studied existing systems, first in a general context, by making the distinction between physical and logical structure recognition systems. Then, we focused on methods specific for complex layout documents and on methods having a learning aptitude. Since there do not seem to exist learning systems which are able to recognise...

Ääs isch es Liebs : weibliches Neutrum und Beziehung im Schweizerdeutschen

Baumgartner, Gerda ; Christen, Helen (Dir.)

Thèse de doctorat : Université de Fribourg, 2021.

Die vorliegende Arbeit widmet sich dem dialektalen Phänomen des weiblichen Neutrums im schweizerdeutschen Rufnamen- und Pronomengebrauch. Ausgangspunkt bildet die Beobachtung, dass nicht nur modifizierte Rufnamen auf -i wie (s) Heidi, sondern auch nicht- modifizierte Rufnamen wie (s) Anna und Pronomen unter Umständen das neutrale Genus führen (Ääs isch es Liebs). Dabei kommt es in...

Absolute configuration determination of the dihydroxyethyl moiety of "hordeum vulgare" chlorophyll catabolites : Enantiomeric excess determination of α-amino acides by 19F NMR spectroscopy with a new fluorinated organometallic chiral derivatizing agent

Levrat, Fabrice ; Engel, Norbert (Dir.) ; Schneider, Manfred (Codir.)

Thèse de doctorat : Université de Fribourg, 2003 ; no 1405.

During senescence, chlorophyll of higher plants is degraded into linear tetrapyrrolic catabolites. Their in vitro oxidation with chromic acid furnishes the constituting pyrrolic moieties as maleimides fragments. The substitution patterns of the isolated maleimides are related to the catabolites structures. All maleimides bear the characteristic methyl group of the former chlorophyll as well as a...

Accounting based valuation and implied discount factor

Brughelli, Moreno ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2012 ; 2012ECO003.

The focus of this doctoral thesis is on the determination of the implied cost of capital in the equity market. Three issues are investigated in detail: the relations between the cost of equity capital, the credit spread and the economic growth; the links between realized market returns and the cost of capital; and the forecasting power of the implied discount factor in predicting market...

Adaptive routing in ad hoc wireless multi-hop networks

Ducatelle, Frederick ; Gambardella, Luca Maria (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2007 ; 2007INFO001.

Ad hoc wireless multi-hop networks (AHWMNs) are communication networks that consist entirely of wireless nodes, placed together in an ad hoc manner, i.e. with minimal prior planning. All nodes have routing capabilities, and forward data packets for other nodes in multi-hop fashion. Nodes can enter or leave the network at any time, and may be mobile, so that the network topology continuously...
