Temporal Scale-Dependent Sensitivity Analysis for Hydrological Model Parameters Using the Discrete Wavelet Transform and Active Subspaces
(Journal article; Peer reviewed, 2021)Global sensitivity analysis is an important step in the process of developing and analyzing hydrological models. Measured data of different variables are used to identify the number of sensitive model parameters and to ... -
Tensor Induction as Left Kan Extension
(Master thesis, 2014-12-02) -
Testing for time-varying nonlinear dependence structures: Regime-switching and local Gaussian correlation
(Journal article; Peer reviewed, 2024)This paper examines nonlinear and time-varying dependence structures between a pair of stochastic variables, using a novel approach which combines regime-switching models and local Gaussian correlation (LGC). We propose ... -

Theoretical Investigation of Heat and Streaming generated by high Intensity Ultrasound
(Department of Applied Mathematics report, Research report, 1998-07) -
Theta-Regularity and Log-Canonical Threshold
(Master thesis, 2018-05-30)The log-canonical threshold is an invariant that is widely used in modern birational geometry. It contains information regarding the singularities of sheaves of ideals. The theta-regularity index is a regularity condition ... -
Thickness and weak integrability & approximation and u-ideals

Threshold estimation based on local minima for nucleus and cytoplasm segmentation
(Journal article; Peer reviewed, 2022)Background: Image segmentation is the process of partitioning an image into separate objects or regions. It is an essential step in image processing to segment the regions of interest for further processing. We propose a ... -
Time Series: Forecasting and Evaluation Methods With Concentration On Evaluation Methods for Density Forecasting
(Master thesis, 2018-06-06)The main focus of this thesis are density forecasts and the corresponding evaluation methods. A density forecast is an estimate of the probability density of predicted values. Density forecasts and the related evaluation ... -
Time-of-Flight Marching + Transport Collapse: An Alternative to Streamlines for Two-Phase Media Flow with Capillary Forces.
(Department of Applied Mathematics report, Research report, 2002-01) -
Tinnitus Is Marginally Associated with Body Mass Index, Heart Rate and Arterial Blood Pressure: Results from a Large Clinical Sample
(Journal article; Peer reviewed, 2023)Introduction: This study aimed to explore whether body mass index (BMI), systolic blood pressure (RR syst), diastolic blood pressure (RR diast) or heart rate (HR) are associated with tinnitus status and/or severity. Methods: ... -
A TMB Approach to Study Spatial Variation in Weather-Generated Claims in Insurance
(Journal article; Peer reviewed, 2023)In this paper, we use TMB to study spatial variation in weather-generated claims in insurance. Our motivation is twofold. By comparing with INLA, we first find that TMB is a robust and efficient approach to deal with spatial ... -
Tokamerarekonstruksjon og Gröbnerbasar
(Master thesis, 2016-06-01)I denne oppgåva skal me sjå på korleis ein skal gå fram for å rekonstruere ei scene frå to bilete. Dette kan brukast når ein skal evaluere satellittbilete og gjere ei kalibrering av kamera. Me skal sjå på geometrien og ... -
Topographic effects on buoyancy driven flows along the slope
(Journal article; Peer reviewed, 2022)The flow and descent of dense water masses formed in shallow regions of the ocean is an important leg in the global overturning circulation. The dense overflow waters tend to flow along the continental slopes as geostrophically ... -
A total pressure-saturation formulation of two-phase flow incorporating dynamic effects in the capillary-pressure-saturation relationship.
(Department of Applied Mathematics report, Research report, 2002-01) -
Total Variation Regularization of Matrix-Valued Images
(Peer reviewed; Journal article, 2007)We generalize the total variation restoration model, introduced by Rudin, Osher, and Fatemi in 1992, to matrix-valued data, in particular, to diffusion tensor images (DTIs). Our model is a natural extension of the color ... -
Toward personalized tinnitus treatment: An exploratory study based on internet crowdsensing
(Peer reviewed; Journal article, 2019-06-25)Introduction: Chronic tinnitus is a condition estimated to affect 10–15% of the population. No treatment has shown efficacy in randomized clinical trials to reliably and effectively suppress the phantom perceptions, and ... -
Towards an understanding of ramified extensions of structured ring spectra
(Journal article; Peer reviewed, 2020)We propose topological Hochschild homology as a tool for measuring ramification of maps of structured ring spectra. We determine second order topological Hochschild homology of the p-local integers. For the tamely ramified ... -
Towards hybrid two-phase modelling using linear domain decomposition
(Journal article; Peer reviewed, 2022)The viscous flow of two immiscible fluids in a porous medium on the Darcy scale is governed by a system of nonlinear parabolic equations. If infinite mobility of one phase can be assumed (e.g., in soil layers in contact ... -
Towards improved monitoring of offshore carbon storage: A real-world field experiment detecting a controlled sub-seafloor CO2 release
(Journal article; Peer reviewed, 2021)Carbon capture and storage (CCS) is a key technology to reduce carbon dioxide (CO2) emissions from industrial processes in a feasible, substantial, and timely manner. For geological CO2 storage to be safe, reliable, and ...
