Novel Bio-compatible Tracers for Positron Emission Particle Tracking
(Peer reviewed; Journal article, 2020)To study the flow of objects in opaque flow processes, the PEPT (positron emission particle tracking) technique may be utilized. The PEPT technique is based on the same principle of positron emission tomography (PET). Both ... -
A novel concentrated, interdisciplinary group rehabilitation program for patients with chronic obstructive pulmonary disease: Protocol for a nonrandomized clinical intervention study
(Peer reviewed; Journal article, 2022)Background: Pulmonary rehabilitation has been demonstrated to be a highly effective treatment for people with chronic obstructive pulmonary disease (COPD). However, its availability is scarce worldwide, and new and ... -
A novel high dimensional fitted scheme for stochastic optimal control problems
(Peer reviewed; Journal article, 2021)Stochastic optimal principle leads to the resolution of a partial differential equation (PDE), namely the Hamilton–Jacobi–Bellman (HJB) equation. In general, this equation cannot be solved analytically, thus numerical ... -
Novel numerical techniques based on mimetic finite difference method for pricing two dimensional options
(Peer reviewed; Journal article, 2022)The Black–Scholes differential operator which underlies the option pricing of European and American options is known to be degenerate close to the boundary at zero. At this singularity, important properties of the differential ... -
A novel patient-reported outcome monitoring with clinical feedback system in bariatric surgery care: study protocol, design and plan for evaluation
(Peer reviewed; Journal article, 2020)Background Consultations before and after bariatric surgery should include structured assessments of patients’ health-related quality of life (HRQOL) and mental health. One way to conduct this assessment is to implement ... -
A novel splice-affecting HNF1A variant with large population impact on diabetes in Greenland
(Peer reviewed; Journal article, 2023)Background The genetic disease architecture of Inuit includes a large number of common high-impact variants. Identification of such variants contributes to our understanding of the genetic aetiology of diseases and improves ... -
A novel synergetic LSTM-GA stock trading suggestion system in Internet of Things
(Peer reviewed; Journal article, 2021)The Internet of Things (IoT) play an important role in the financial sector in recent decades since several stock prediction models can be performed accurately according to IoT-based services. In real-time applications, ... -
Now What? Collective Sensemaking and Sensegiving in the Cystic Fibrosis Community in Sweden During the Initial Phase of the COVID-19 Pandemic
(Peer reviewed; Journal article, 2022)The COVID-19 pandemic’s effects on people’s lives and society induced a need for rapid individual and collective sensemaking, including communication forums enabling stakeholders in the health ecosystem to share information, ... -

Numerical Analysis of an Articulated Hybrid Offshore Wind Turbine Concept
(Peer reviewed; Journal article, 2023)The concept of a "hybrid offshore wind turbine" originated from articulated loading platforms (ALPS). In this study, we have developed a concept design for the major structural components. Orcaflex was used to create a ... -
Numerical analysis of erosion due to nanoparticles in a pipe elbow
(Journal article; Peer reviewed, 2018)Flows of fluids laden with small particles in pipes are common in industry. An interesting and still unexplored issue is erosion of walls due to impact of particles. The main focus of our research was on nanoparticles. ... -
Numerical analysis of fire-driven smoke plumes in the atmosphere
(Master thesis, 2017)Plumes originating from fires may serve as a risk for people and environmental safety. Depending on what fuels a fire the content of the plume will vary [1]. From simple carbonaceous soot particulates, known to cause ... -
