We present a random walk approximation to fractional Brownian motion where the increments of the fractional random walk are defined as a weighted sum of the past increments of a Bernoulli random walk.
Pulsatile flow in bifurcation with aneurysm using µPTV technique Restricted Access
(Master thesis / Masteroppgave, 2009)
An important topic in biomechanical flow is the study of aneurysms. Aneurysm can be found in bifurcation and curved blood vessels. These can rupture leading to life threatening situations.
In this thesis we will look at ...

In this work we characterize the smooth surfaces which can be embedded in the Grassmannian G(1,5) with one apparent double point, i.e. such that the general projection to G(1,3) produces just one double point. The result ...
Mortalitetsvingninger og kapital på lang sikt Restricted Access
(Master thesis / Masteroppgave, 2009)
Endringer i dødelighetsmønstre er et område som forsikringsbransjen har lagt mer og mer vekt på den siste tiden. Dette er som følge av at man over lengre tid har observert en stadig økning i menneskets forventede ...

The main objective of this work is to construct optimal temperature futures from available market-traded contracts to hedge spatial risk. Temperature dynamics are modelled by a stochastic differential equation with spatial ...

We consider a combinatorial problem motivated by a special simplified timetabling problem for subway networks. Mathematically the problem is to find (pairwise) disjoint congruence classes modulo certain given integers; ...

Starting with a problem in wireless telecommunication, we are led to study the multiple knapsack problem with assignment restrictions. This problem is NP-hard. We consider special cases and their computational complexity. ...
