This thesis treats traffic as flow in static and dynamic networks. This may be any kind of traffic; cars, information etc. Two flows are of particular interest: The system optimum, which minimizes total travel time for all ...

Representasjonsteori er et område innenfor matematikken hvor man representer- er elementer i grupper og algebraer med lineære transformasjoner av vektorrom. I lineær algebra finnes det mye verktøy, og dette kan man bruke ...

In "Information Retrieval", relevance is a numerical score assigned to a search result, representing how well the results meet the information need of the user that issued the search query. In many cases, a result's relevance ...

We study a mean-reverting model for interest rates. The model is an extension of the Vasicek model and is a sum of non-Gaussian Ornstein-Uhlenbeck processes with subordinators, i.e. Lévy processes with only positive jumps, ...

There is a connection between representations of the fundamental group π_1(X) of a compact Riemann surface X, and holomorphic vector bundles on X. More specifically, for every representation ρ, there exists an associated ...

The Cox ring of a smooth algebraic projective variety X is the direct sum of H^0(X,D) as D varies in the Picard group of X. The ring was introduced by Y. Hu and S. Keel in 2000 and generalizes Cox' construction of the ...

In this thesis I study alternatives to the geometric Brownian motion where the log-return follow Lévy processes with jumps, in particular the normal invers Gaussian and the CGMY Lévy processes. With focus on Merton's ...

Cluster analysis is a field of study where the aim is to discover distinct groups or clusters in a data set. The objects in the same groups should be similar to each other in some respect, while at the same time dissimilar ...
