(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In this paper, we consider the noise effects on a class of stochastic evolution equations including the stochastic Camassa–Holm equations with or without rotation. We first obtain the existence, uniqueness and a blow-up ...

(Doctoral thesis / Doktoravhandling, 2010)Marine seismic is a well established method to search for subsurface hydrocarbon deposits. However, the method is often limited by various sources of noise, of which flow and swell noise are the dominating types. This study ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Motivated by the problem of characterizing KMS states on the reduced C∗-algebras of étale groupoids, we show that the reduced norm on these algebras induces a C∗-norm on the group algebras of the isotropy groups. This ...

(Research report / Forskningsrapport, 2005)We propose an mean-reverting model for the spot price dynamics of electricity which includes seasonality of the prices and spikes. The dynamics is a sum of non-Gaussian Ornstein-Uhlenbeck processes with jump processes ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Invasive monitoring of pulsatile intracranial pressure can accurately predict shunt response in patients with idiopathic normal pressure hydrocephalus, but may potentially cause complications such as bleeding and infection. ...

(Master thesis / Masteroppgave, 2012)Repair of a damaged ship hull is time and cost consuming in shipping industry. A damage is something that often sets the ship operation out of business and every part that has an interest, are looking for ways to minimize ...

(Master thesis / Masteroppgave, 2015)Lending money has been one of the basic activities of banks for centuries. However, credit evaluation and pricing of loans are still not well understood, since the assessment of the impact of credit risk on prices in bond ...

(Research report / Forskningsrapport, 2011)We prove an existence and uniqueness result for non-linear time-advanced backward stochastic partial di erential equations with jumps (ABSPDEJs). We then apply our results to study a time-advanced backward type of stochastic ...
