Potential and limitation of 230Th-excess as a chronostratigraphic tool for late Quaternary Arctic Ocean sediment studies: An example from the Southern Lomonosov Ridge
(Journal article; Peer reviewed, 2022)Recently, the use of “extinction ages” of excesses in U-series isotopes (230Thxs, 231Paxs) has been proposed for the setting of benchmark ages of up to ~350 and ~150 ka, respectively, in late Quaternary marine records from ... -
Training a supermodel with noisy and sparse observations: A case study with CPT and the synch rule on SPEEDO-v.1
(Journal article; Peer reviewed, 2022)As an alternative to using the standard multi-model ensemble (MME) approach to combine the output of different models to improve prediction skill, models can also be combined dynamically to form a so-called supermodel. The ... -
Understanding climate change impacts on biome and plant distributions in the Andes: Challenges and opportunities
(Journal article; Peer reviewed, 2022)Aim: Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the ... -
The role of air–sea coupling on November–April intraseasonal rainfall variability over the South Pacific
(Journal article; Peer reviewed, 2022)We investigate the impact of resolving air-sea interaction on the simulation of the intraseasonal rainfall variability over the South Pacific using the ECHAM5 atmospheric general circulation model coupled with the ... -
Arctic Ocean Amplification in a warming climate in CMIP6 models
(Journal article; Peer reviewed, 2022)Arctic near-surface air temperature warms much faster than the global average, a phenomenon known as Arctic Amplification. The change of the underlying Arctic Ocean could influence climate through its interaction with sea ... -
The Role of Mid-latitude Westerly Jet in the Impacts of November Ural Blocking on Early-Winter Warmer Arctic-Colder Eurasia Pattern
(Journal article; Peer reviewed, 2022)Based on statistical analysis using observations and idealized model simulations, previous studies have revealed the potential response of early-winter atmospheric circulation and temperature anomalies to November Ural ... -
Dansgaard-Oeschger and Heinrich event temperature anomalies in the North Atlantic set by sea ice, frontal position and thermocline structure
(Journal article; Peer reviewed, 2022)We use eighteen timescale-synchronised near-surface temperature reconstructions spanning 10–50 thousand years before present to clarify the regional expression of Dansgaard-Oeschger (D-O) and Heinrich (H) events in the ... -
Mathematical modelling of follicular growth and ovarian stimulation
(Journal article; Peer reviewed, 2022)The aim of ovarian stimulation in fertility treatment is to increase the number of large follicles and hence the number of eggs that can be retrieved for in vitro fertilisation (IVF). However, large inter- and intra-individual ... -
The impact of turbulence modelling on large offshore wind turbine response
(Doctoral thesis, 2022-10-28)In order to reduce climate change, a large up-scaling of renewable energy capacity is necessary in the near future. Offshore wind is expected to play a key role in this green shift. The wind conditions offshore are in ... -
A case-control study of linear energy transfer and relative biological effectiveness related to symptomatic brainstem toxicity following pediatric proton therapy
(Journal article; Peer reviewed, 2022)Background and purpose A fixed relative biological effectiveness (RBE) of 1.1 (RBE1.1) is used clinically in proton therapy even though the RBE varies with properties such as dose level and linear energy transfer (LET). ... -
Distribution and Occurrence Frequency of dB/dt Spikes During Magnetic Storms 1980–2020
(Journal article; Peer reviewed, 2022)The physical magnetospheric cause for geomagnetically induced currents (GICs) are rapid time-varying magnetic fields (dB/dt), which occur mainly during magnetic substorms and storms. When, where and why exactly such rapid ... -
Triplicate functions
(Journal article; Peer reviewed, 2022)We define the class of triplicate functions as a generalization of 3-to-1 functions over \(\mathbb {F}_{2^{n}}\) for even values of n. We investigate the properties and behavior of triplicate functions, and of 3-to-1 among ... -
Acoustic Delicing of Atlantic Salmon (Salmo salar): Fish Welfare and Salmon Lice (Lepeophtheirus salmonis) Dynamics
(Journal article; Peer reviewed, 2022)Acoustic lice treatment (AcuLice) is a newly developed system, which uses a composite acoustic sound image with low-frequency sound to remove salmon lice (Lepeophtheirus salmonis) from Atlantic salmon (Salmo salar). This ... -
Geometric rough paths on infinite dimensional spaces
(Journal article; Peer reviewed, 2022)Similar to ordinary differential equations, rough paths and rough differential equations can be formulated in a Banach space setting. For α ∈ (1/3,1/2), we give criteria for when we can approximate Banach space-valued ... -
Wirom2.0: An Extensible System for Mission Planning of Heterogeneous Multi-Robot Teams
(Master thesis, 2022-06-01)Robotics software systems are becoming increasingly more complex, which makes the development progressively more challenging. Heterogeneous robots have different requirements, and their actions need different specifications ... -
Room of Errors - Feasibility and Design of a Simulation Training Concept in VR with Intentional Simulation Errors
(Master thesis, 2022-06-01)In 2020, 13.1 percent of somatic hospital stays in Norway led to hospital-acquired complications or injuries. One way of working to prevent these events may be found in the education of health personnel. Nursing study ... -
Ecological Momentary Assessment in Internet-Delivered Psychological Treatments using Wearable Technology
(Master thesis, 2022-06-01)The growing prevalence of mental health problems is a global concern. Current psychological treatments are effective for a wide range of mental health problems. Yet, treatments today fall short with regards to scalability ... -
A workflow-integrated brain tumor segmentation system based on fastai and MONAI
(Master thesis, 2022-06-01)Artificial intelligence (AI) has achieved great results in medical imaging tasks and has the potential to improve the experiences of clinicians and patients in the future, but on the way toward AI integration in medicine, ... -
Towards Developing an Eye-tracker Based Virtual Reality Application for Supporting Vision Screening
(Master thesis, 2022-08-01)Statistics from 2014 show that 35 to 75 percent of school age children suffer from some sort of vision problem. Of these children, around 25\% have normal visual acuity, however, their problems relate to low performance ...
