Rotating shaft's non-linear response statistics under biaxial random excitation, by path integration
(Journal article; Peer reviewed, 2018)The response of rotating shaft to random excitations is of practical concern for various rotor type engine design applications, with high level of potential external forces of stochastic nature. Authors have studied ... -
Rotation of the onion state in micromagnetic rings
(Master thesis, 2013)The behavior of the movement of the two domain walls that make up the onion state in 5 μm Permalloy rings have been studied under rotation using longitudinal magneto-optical Kerr effect. Resistance to the domain wall motion ... -
Rotation Representations Methods for Pose Estimation with Deep Learning
(Master thesis, 2022)Problemstillingen med å estimere rotasjonsmatriser i 3D er et gammelt problem i datasyn som har gjenoppstått sammen med den ekstreme økningen av metoder i dyp læring. Det har blitt forsøkt å benytte nevrale nettverk for ... -
Rotation sequence and marker tracking method affects the humerothoracic kinematics of manual wheelchair propulsion
(Peer reviewed; Journal article, 2022)The literature on shoulder (humerothoracic) kinematics in manual wheelchair propulsion is growing. Inconsistencies in the reporting of which rotation sequence is used to compute three-dimensional (3D) angles complicates ... -
Rotational CPTU method: development and testing of an innovative sounding approach for rapid and accurate in-situ detection of quick clay
(Master thesis, 2023)Denne oppgaven presenterer en innovativ geoteknisk feltundersøkelsesmetode - den roterende CPTU-metoden (forkortet DRTCPT), for rask og nøyaktig in-situ detektering av omfattende kvikkleiresedimentering. Den nye metoden ... -
Rotational Curves of the Milky Way Galaxy and Andromeda Galaxy in Light of Vacuum Polarization around Eicheon †
(Peer reviewed; Journal article, 2023)Eicheon properties are discussed. It is shown that the eicheon surface allows setting a boundary condition for the vacuum polarization and obtaining a solution describing the dark matter tail in the Milky Way Galaxy. That ... -
Rotational Diffusion Processes in Segmented Polymers. Theory and Computer Simulations
(Dr.ingeniøravhandling, 0809-103X; 2002:139, Doctoral thesis, 2003)All biological macromolecules (DNA, RNA, proteins, polysaccarids) are polymers. These are extremely complex systems, with thousands or millions of atomic degrees of freedom. However, a range of important properties of such ... -
Rotations in Factor Analysis
(Bachelor thesis, 2022)Denne oppgaven vil omhandle faktoranalyse med hovedfokus på faktormodellens rotasjoner. Rotasjoner brukes både for å kunne trekke slutninger og for å bedre tolke dataene. I denne sammenheng vil vi se på kriteriene som er ... -
Rotatorier som levendefor til torskeyngel
(Research report, 2011)Stabil og forutsigbar produksjon av rotatorier er avgjørende for å lykkes med marin yngelproduksjon. I denne rapporten gis det en innføring i dagens kunnskap knyttet til rotatorier (DPI). Dette omfatter tema som generell ... -
Rotavirus detection in bulk stool and rectal swab specimens in children with acute gastroenteritis in Norway
(Journal article; Peer reviewed, 2017)Background Bulk stool specimens are traditionally used for rotavirus detection but may be challenging to obtain from young children. Immediate and easy sampling may however be required in different situations, such as ... -
Rotårsaksanalyser
(Master thesis, 2010)Målet med masteroppgaven har vært å utvikle en håndbok for rotårsaksanalyser (RCA) som landorganisasjonen til Odfjell Drilling kan benytte. Bakgrunnen for utviklingen av håndboken var den økende bevisstheten rundt verktøyet ... -
