• Inference in cylindrical models having latent Markovian classes - with an application to ocean current data 

  Lie, Henrik Syversveen; Eidsvik, Jo (Peer reviewed; Journal article, 2021)

  Spatial direction vector data can be represented cylindrically by linear magnitudes and circular angles. We analyze such data by using a hierarchical Markov random field model with latent discrete classes and conditionally ...

• Contact Wire Irregularity Stochastics and Effect on High-speed Railway Pantograph-Catenary Interactions 

  Song, Yang; Liu, Zhigang; Rønnquist, Anders; Nåvik, Petter Juell; Liu, Zhendong (Peer reviewed; Journal article, 2020)

  In high-speed rail operations, contact wire irregularity (CWI) in a catenary is a common disturbance to the pantograph-catenary interaction performance, which directly affects the quality of current collection. To describe ...

• Current and Future Prevalence Estimates of Mild Cognitive Impairment, Dementia, and Its Subtypes in a Population-Based Sample of People 70 Years and Older in Norway: The HUNT Study 

  Gjøra, Linda; Strand, Bjørn Heine; Bergh, Sverre; Borza, Tom; Brækhus, Anne; Engedal, Knut Arne; Johannessen, Aud; Kvello-Alme, Marte; Krokstad, Steinar; Livingston, Gill; Matthews, Fiona E; Myrstad, Christian; Skjellegrind, Håvard; Thingstad, Pernille; Aakhus, Eivind; Aam, Stina; Selbæk, Geir (Peer reviewed; Journal article, 2021)

  Background: Having accurate, up-to-date information on the epidemiology of mild cognitive impairment (MCI) and dementia is imperative. Objective: To determine the prevalence of MCI and dementia in Norway using data ...

• UV degradation of natural and synthetic microfibers causes fragmentation and release of polymer degradation products and chemical additives 

  Sørensen, Lisbet; Groven, Anette Synnøve; Hovsbakken, Ingrid Alver; Del Puerto, Oihane; Krause, Daniel Franklin; Sarno, Antonio; Booth, Andrew (Peer reviewed; Journal article, 2020)

  A high proportion of the total microplastic (MP) load in the marine environment has been identified as microfibers (MFs), with polyester (PET) and polyamide (PA) typically found in the highest abundance. The potential for ...

• Comparing C5Pe and Asphaltenes under Temperature and Pressure Reservoir Conditions Using an Acoustic Wave Sensor 

  Cassiède, Marc; Carrier, Hervé; Daridon, Jean-Luc; Simon, Sebastien Charles; Sjøblom, Johan (Peer reviewed; Journal article, 2021)

  A quartz crystal resonator (QCR) was employed to assess the ability of the C5Pe model asphaltene compound to form nanoaggregates in toluene and bigger flocs that adsorb on the QCR surfaces at a higher concentration of ...
