Validation study of ReaxFF-optimized geometries in ruthenium compounds
(Master thesis, 2014-03-14)The present thesis, describes a validation study of ReaxFF-optimized geometries, through statistical tools (i) weighted root mean square of distances and (ii) interatomic distances having as reference 786 X-ray and 11 DFT ... -
Variability in the formation and framework polymorphism of metal-organic frameworks based on yttrium(III) and the bifunctional organic linker 2,5-dihydroxyterephthalic acid
(Journal article; Peer reviewed, 2021)Depending on the solvothermal reaction conditions, we obtained three different metal‐organic frameworks with yttrium(III) as metal component and 2,5‐dihdyroxyterepthalic acid (H4dhtp) as bifunctional organic linker: ... -
Variability of perfusion estimates from synthetic and clinical magnetic resonance imaging data
(Master thesis, 2023-02-13) -
Variable importance: Comparison of selectivity ratio and significance multivariate correlation for interpretation of latent‐variable regression models
(Journal article; Peer reviewed, 2020)This work examines the performance of significance multivariate correlation (sMC) and selectivity ratio (SR) for ranking variables according to their importance in latent-variable regressions (LVRs) models. Both indices ... -
Variable selection optimization for multivariate classification of metabolomics data
(Master thesis, 2013-05-21)Variable selection is an important step in multivariate calibration in which the number of variables in the independent variable matrix is reduced by eliminating those that are not related to the response. Many methods ... -
Variation in Phenolic Chemistry in Zostera marina Seagrass along Environmental Gradients
(Journal article; Peer reviewed, 2021)Chemical ecology has been suggested as a less time-consuming and more cost-efficient monitoring tool of seagrass ecosystems than traditional methods. Phenolic chemistry in Zostera marina samples was analyzed against latitude, ... -
Variation of desolvation behavior in two isostructural metal–organic frameworks based on a flexible, racemic bifunctional organic linker
(Journal article; Peer reviewed, 2016)A racemic mixture of the chiral ligand 4,4′-(1,2-dihydroxyethane-1,2-diyl)dibenzoic acid was used to prepare two isostructural metal–organic frameworks, CPO-49-Zn and CPO-49-Mn, which contain coordinated solvent molecules ... -
Vertical distribution of inorganic nanoparticles in a Norwegian fjord
(Journal article; Peer reviewed, 2023)Due to the analytical challenges of detecting and quantifying nanoparticles in seawater, the data on distributions of NPs in the marine environment is limited to qualitative studies or by ensemble measurements subject to ... -
Vessel recognition in ultrasound images using machine learning techniques
(Master thesis, 2023-06-02)Purpose: Ultrasound is an imaging modality that is commonly used during cardiovascular surgeries globally. The purpose of this thesis is to investigate how machine learning techniques can be used to identify vessel properties ... -
Viscosity and Viscoelastic Properties in Hydrophobically Modified Polymers for Enhanced Oil Recovery
(Doctoral thesis, 2019-01-25)Polymers have been studied and used for mobility control since the 1960s and found to improve the mobility ratio between the injected fluid and the displaced oil. However, small changes in polymer structure and/or relation ... -
Volume Increase of the Hippocampus after Electroconvulsive Therapy - The Role of the Electric Field and the Individual Differences due to Body Mass Index, Sex and Age
(Master thesis, 2021-06-15)Electroconvulsive therapy (ECT) involves passing an electrical current through the brain, intentionally causing a brief seizure. In Norway, it is common to calculate the dose according to an age-based method. Recent studies ... -
Volumetric properties of the nucleosides adenosine, cytidine, and uridine in aqueous solution at T = (288.15 and 313.15) K and p = (10 to 100) MPa
