Quivers, Gröbner bases, and tensor products
(Master thesis, 2022)Vi presenterer teori for Gröbner-basis i algebraer med multiplikativ basis, og spesielt for Gröbner-basis i vei-algebraer. Vi viser hvordan man kan konstruere tensorproduktet $\Lambda \otimes_K \Gamma$ av algebraer $\Lambda$ ... -
R1-elevers begrepsbilde av bevis i geometri - En studie av R1-elevers syn på bevis i geometri, og samspillet mellom begrepsbilder av bevis og argumentasjon
(Master thesis, 2018)Denne studien tar for seg hvordan R1-elevers begrepsbilde av bevis ser ut i geometri, hvordan elevene argumenterer i geometri, og hvilken sammenheng det er mellom elevers begrepsbilde av bevis og hvordan de argumenterer. ... -
Radical cube zero self injective algebras and support varieties
(Doctoral thesis at NTNU;2015:157, Doctoral thesis, 2015) -
Railway condition monitoring applying the continuous and discrete wavelet transforms
(Master thesis, 2020)Den diskrete og den kontinuerlige bølgetransformasjonen er anvendt på geometrimålinger som en metode for å overvåke sporgeometri i den danske jernbanens sporvekslinger. Geometrimålinger samles regelmessig for hele ... -
Rapid Seismic Inversion for Isolated Singularities
(Master thesis, 2008)Thin layers can cause problems in inversion algorithms as the material parameters and the thickness of the layer are inseparable. Here a thin layer model is developed where a thin sand layer embedded in shale is considered ... -
Rational local systems and connected finite loop spaces
(Peer reviewed; Journal article, 2021)Greenlees has conjectured that the rational stable equivariant homotopy category of a compact Lie group always has an algebraic model. Based on this idea, we show that the category of rational local systems on a connected ... -
Rational Noncommutative Tori and Gabor Frames
(Master thesis, 2016)A link between noncommutative geometry and time-frequency analysis is used to show that the TKNN equation violates existence results for Gabor frames with atoms in the Schwartz space. In particular, we use that the Schwartz ... -
Rational Tambara functors
(Doctoral theses at NTNU;2017:95, Doctoral thesis, 2017) -
Real time ultrasound simulation: Application to a medical training simulator
(Master thesis, 2008)As ultrasound technology today finds new applications and becomes available to more and more users, the demand for good training procedures and material increases. This has motivated a research project aimed at developing ... -
Real-time forecasting of emergency department arrivals using prehospital data
(Journal article; Peer reviewed, 2019)Background: Crowding in emergency departments (EDs) is a challenge globally. To counteract crowding in day-to-day operations, better tools to improve monitoring of the patient flow in the ED is needed. The objective of ... -
Real-Valued Algebro-Geometric Solutions of the Two-Component Camassa–Holm Hierarchy
(Journal article; Peer reviewed, 2017)We provide a construction of the two-component Camassa– Holm (CH-2) hierarchy employing a new zero-curvature formalism and identify and describe in detail the isospectral set associated to all real-valued, smooth, and ... -
Realizability and the Avrunin-Scott theorem for higher-order support varieties
(Journal article; Peer reviewed, 2018)We introduce higher-order support varieties for pairs of modules over a commutative local complete intersection ring and give a complete description of which varieties occur as such support varieties. In the context of a ... -
Realization functors and HRS-tilting
(Master thesis, 2021)La A vær en abelsk kategori, og H vær det abelske hjertet til en t-struktur over Db(A). Vi vil da vise at vi alltid kan konstruere en "realization functor" Db(H) -> Db(A), som restriktert til H vil være lik identitetsfun ... -
Realized GARCH: Evidence in ICE Brent Crude Oil Futures Front Month Contracts
(Master thesis, 2012)This paper extends standard GARCH models of volatility with realized measures for the realized GARCH framework. A key feature of the realized GARCH framework is the measurement equation that relates the observed realized ... -
Realizing orbit categories as stable module categories: a complete classification
(Journal article; Peer reviewed, 2017)We classify all triangulated orbit categories of path-algebras of Dynkin diagrams that are triangle equivalent to a stable module category of a representation-finite self-injective standard algebra. For each triangulated ... -
Recollections of V. S. Varadarajan
(Peer reviewed; Journal article, 2020)Known to friends, students, and colleagues just as Raja, Veeravalli Seshadri Varadarajan (born May 18, 1937) was a mathematician of Indian origin who made foundational contributions to multiple fields, including probability, ... -
Recommendations for quantitative uncertainty consideration in ecology and evolution
(Peer reviewed; Journal article, 2023)Ecological and evolutionary studies are currently failing to achieve complete and consistent reporting of model-related uncertainty. We identify three key barriers – a focus on parameter-related uncertainty, obscure ... -
Recovering a Variable Exponent
(Journal article; Peer reviewed, 2021) -
Rectangular Summation of Multiple Fourier Series and Multi-parametric Capacity
(Peer reviewed; Journal article, 2021)We consider the class of multiple Fourier series associated with functions in the Dirichlet space of the polydisc. We prove that every such series is summable with respect to unrestricted rectangular partial sums, everywhere ... -
Recurrent Neural Network for Learning and Reproducing Movements
(Master thesis, 2007)In this thesis I study how movements can be learned and stored by a recurrent neural network. Also I investigate how a movement can be associated with an external context, and wether this can be used to produce movements ...
