Road-map for gas in the Norwegian metallurgical industry: greater value creation and reduced emissions
(Research report, 2017)In order to increase the use of gas in metal production, we will need to develop new – and to further develop existing – gas-based technologies, which will need to be adopted on an industrial scale. In order to provide a ... -
Roads with underlying tar asphalt - spreading, bioavailability and toxicity of their polycyclic aromatic hydrocarbons
(Peer reviewed; Journal article, 2021)Some of the older Swedish roads contain road tar underneath a surface layer of bituminous asphalt. This road tar, also known as tar asphalt, contains large amounts of polycyclic aromatic hydrocarbons (PAHs). There is concern ... -
Robot Control in Image-Guided Intervention
(Master thesis, 2016)Introducing autonomous robot systems in clinical medicine is deemed extremely challenging due to the complex scene involved and variations between patients. The majority of commercialized systems are controlled directly ... -
Robotic optical observations of compact binary millisecond pulsars
(Master thesis, 2023)Denne masteroppgaven fokuserer på robotiske optiske observasjoner av den kompakte dobbeltstjerne-millisekundpulsaren PSR J1048+2339, utført ved hjelp av Joan Oró-teleskopet (TJO). Som en del av masterarbeidet ble en ... -
A robust algorithm for rate-independent crystal plasticity
(Peer reviewed; Journal article, 2022)A new stable return-mapping algorithm enables crystal-plasticity solutions by using a regularized yield surface with very large exponents, for which the rate-independent limit of the Schmid assumption in practice is reached. ... -
Robust analysis of fluxes in genome-scale metabolic pathways
(Journal article; Peer reviewed, 2017)Constraint-based optimization, such as flux balance analysis (FBA), has become a standard systems-biology computational method to study cellular metabolisms that are assumed to be in a steady state of optimal growth. The ... -
Robust bacterial co-occurence community structures are independent of r- and K-selection history.
(Peer reviewed; Journal article, 2021)Selection for bacteria which are K-strategists instead of r-strategists has been shown to improve fish health and survival in aquaculture. We considered an experiment where microcosms were inoculated with natural seawater ... -
Robust control solutions for stabilizing flow from the reservoir: S-Riser experiments
(Master thesis, 2013)One of the best suggested solutions for prevention of severe-slugging flow conditions at offshore oilfields is the active control of the production choke valve. This thesis is a study of robust control solutions for ... -
A Robust Image Processing Algorithm for Optical-Based Stress–Strain Curve Corrections after Necking
(Peer reviewed; Journal article, 2021)To determine the stress–strain curve of a ductile material up to the fracture from a tensile test, the necking contour is measured by an optical measurement technique. The radius of the minimal cross-sectional area and the ... -
A Robust Learning Methodology for Uncertainty-Aware Scientific Machine Learning Models
(Journal article; Peer reviewed, 2023) -
Robust Magnetic Surface Doping of Transition Metal Dichalcogenides
(Master thesis, 2016)The growth and potential intercalation of Fe on naturally grown MoS$_{2}$ has been studied using a number of surface techniques. An initial sample characterization revealed that samples extracted from the natural MoS$_{2}$ ... -
A Robust Method for Analysing One and Two-Dimensional Dynamic NMR Data
(Peer reviewed; Journal article, 2022)A new method combining Anahess and Inverse Laplace Transform, for analysing one- and two-dimensional dynamic NMR data has been developed. When using the Inverse Laplace Transform (ILT) algorithm only to generate solutions ... -
ROBUSTNESS ANALYSIS OF RADIATION TREATMENT PLANS FOR BREAST CANCER, A COMPARATIVE STUDY BETWEEN PROTONS AND PHOTONS
(Master thesis, 2019)Protonterapi gir teoretisk sett en forbedret dosefordeling og dermed et mulig gunstigere behandlingsresultat for brystkreftpatienter enn fotonterapi. Teknikken har et stort potensiale for å spare risikoorganer, som for ... -
Robustness of linear mixed-effects models to violations of distributional assumptions
(Peer reviewed; Journal article, 2020)Linear mixed-effects models are powerful tools for analysing complex datasets with repeated or clustered observations, a common data structure in ecology and evolution. Mixed-effects models involve complex fitting procedures ... -
Robustness of nitrifying biofilter functionality: Role of competition between heterotrophic and nitrifying bacteria on ammonium removal efficiency and microbial community structure
(Master thesis, 2017)Removal of ammonium by nitrification in biofilm systems is a common method in wastewater treatment. The ammonium removal efficiency in the nitrification process is influenced by the competition between nitrifying bacteria ... -
Rochelle salt - A structural reinvestigation with improved tools. I. the high-temperature paraelectric phase at 308 - K
(Peer reviewed; Journal article, 2015)The crystal structure of the high-temperature paraelectric phase of Rochelle salt (K+·Na+·C4H4O62−·4H2O) at 308 K has been reinvestigated using synchrotron X-ray diffraction with refinement parameters R(int) = 0.0123, final ... -
Rodent population dynamics affect seedling recruitment in alpine habitats
(Journal article; Peer reviewed, 2014)Questions How do rodents with cyclic population dynamics affect seedling recruitment in alpine habitats? Does disturbance from rodents have larger implications on seedling recruitment in some plant communities than in ... -
Roe deer face competing risks between predators along a gradient in abundance
(Journal article; Peer reviewed, 2013)Mortality rates and patterns are fundamental demographic traits for understanding the dynamics of populations of large herbivores in different environments. Despite the ongoing recovery of large carnivores in Europe and ... -
Rognkjeks i fullskala laksemerder
