PTA-metrics for time-lapse analysis of well performance
(Peer reviewed; Journal article, 2023)Monitoring of a well and the surrounding reservoir performances is a crucial component in evaluating on-going and planning future well and field operations. This is carried out at all stages of a well life-span: from ... -
Assistive Data Glove for Isolated Static Postures Recognition in American Sign Language Using Neural Network
(Peer reviewed; Journal article, 2023)Sign language recognition is one of the most challenging tasks of today’s era. Most of the researchers working in this domain have focused on different types of implementations for sign recognition. These implementations ... -
No room to hide: implications of cosmic-ray upscattering for GeV-scale dark matter
(Peer reviewed; Journal article, 2023)The irreducible upscattering of cold dark matter by cosmic rays opens up the intriguing possibility of detecting even light dark matter in conventional direct detection experiments or underground neutrino detectors. The ... -
Insights from Boltzmann transformation in solving 1D counter-current spontaneous imbibition at early and late time
(Peer reviewed; Journal article, 2023)Counter-current 1D spontaneous imbibition in scaled form is investigated using Boltzmann transform before and after water meets the closed boundary (early and late time). At early time the system is self-similar and only ... -
Beyond cuts in small signal scenarios: Enhanced sneutrino detectability using machine learning
(Peer reviewed; Journal article, 2023)We investigate enhancing the sensitivity of new physics searches at the LHC by machine learning in the case of background dominance and a high degree of overlap between the observables for signal and background. We use two ... -
Early- and Late-Time Prediction of Counter-Current Spontaneous Imbibition, Scaling Analysis and Estimation of the Capillary Diffusion Coefficient
(Peer reviewed; Journal article, 2023-03)Solutions are investigated for 1D linear counter-current spontaneous imbibition (COUSI). It is shown theoretically that all COUSI scaled solutions depend only on a normalized coefficient Λn (Sn) with mean 1 and no other ... -
Study of the Effects of Alkali Treatment and Fiber Orientation on Mechanical Properties of Enset/Sisal Polymer Hybrid Composite
(Peer reviewed; Journal article, 2023-01)Abstract In the manufacturing process of innovative fiber-based composite materials, natural fibers are among the most commonly employed reinforcements. In this study, Enset/Sisal (E/S) fiber with a polyester matrix was ... -
A natural Hessian approximation for ensemble based optimization
(Peer reviewed; Journal article, 2023)A key challenge in reservoir management and other fields of engineering involves optimizing a nonlinear function iteratively. Due to the lack of available gradients in commercial reservoir simulators the attention over the ... -
Tidserier for finansiell data
(Bachelor thesis, 2023)The motivation for this thesis is to grasp general theory and principles for modeling time series, for the application to financial data. By going through the theory that makes up this field and bringing that perception ... -
Texture-modified salmon products for dysphagia patients
(Bachelor thesis, 2023)Consuming food plays an important role in a person's quality of life. Dysphagia is a medical condition where chewing and swallowing are difficult, and this condition is most common among the elderly. It can lead to ... -

Towards learning optimized kernels for complex Langevin
(Peer reviewed; Journal article, 2023)We present a novel strategy aimed at restoring correct convergence in complex Langevin simulations. The central idea is to incorporate system-specific prior knowledge into the simulations, in order to circumvent the NP-hard ... -
Towards Posture and Gait Evaluation through Wearable-Based Biofeedback Technologies
(Peer reviewed; Journal article, 2023)In medicine and sport science, postural evaluation is an essential part of gait and posture correction. There are various instruments for quantifying the postural system’s efficiency and determining postural stability which ... -
Rheology assessment and barite sag in a typical North Sea oil-based drilling fluid at HPHT conditions
(Peer reviewed; Journal article, 2023)The occurrence of barite sag in drilling fluids has relatively often been the cause for gas kicks in oilwell drilling. The subsequent absorption of gas into drilling fluid could lower the density and reduce the viscosity ... -
A risk and safety science perspective on the precautionary principle
(Peer reviewed; Journal article, 2023)The precautionary principle is strongly debated as a policy for handling risk and safety concerns. It is commonly claimed that the principle is paralyzing, unscientific and promotes a culture of irrational fear. The risk ... -
