Flow of cerebrospinal fluid (CSF) in perivascular spaces (PVS) is one of the key concepts involved in theories concerning clearance from the brain. Experimental studies have demonstrated both net and oscillatory movement ...
Merton’s portfolio problem: A Monte Carlo study Restricted Access
(Master thesis / Masteroppgave, 2021)
A classical problem in continuous time finance is Merton’s portfolio problem. The problem was formulated and solved in 1969 by economist and Nobel prize winner Robert C. Merton. At each instant of time, a risk averse ...

The objective of the thesis is to investigate Markov structures of time changed Lévy processes. Moreover we investigate the Markov structures of stochastic differential equations driven by Brownian motion with a view towards ...

We introduce a rough perturbation of the Navier–Stokes system and justify its physical relevance from balance of momentum and conservation of circulation in the inviscid limit. We present a framework for a well-posedness ...

We argue that the very effective cover of hermitian K-theory in the sense of motivic homotopy theory is a convenient algebro-geometric generalization of the connective real topological K-theory spectrum. This means the ...

In this note we consider the asymptotic power functions of some bootstrap unit root tests under local alternatives and show that they are in fact the same as for ordinary unit root tests. This is regardless of whether the ...

Landslide tsunamis and impulse waves are hazardous events with severe socioeconomic impacts. A long standing problem with simulations of these events is the generation stage, where landslides and water interact. Depth-averaged ...

Output voltage regulation of DC–DC converters has recently gained an increasing attention to face the many system nonidealities. The fast switching behavior is nonlinear time varying, the presence of model and measurement ...
