Comparison of AC-Superconducting Multi-Phase Symmetric-Winding Topologies for Wind Power Generators with PM Rotors
(Peer reviewed; Journal article, 2022)In this paper, an AC superconducting multi-phase symmetric-winding machine is designed for a wind power generator to improve its performance and reduce losses, where four handpicked topological designs were explored and ... -
Characterization of the Electrical Properties of a Double Heterostructure GaN/AlGaN Epitaxial Layer with an AlGaN Interlayer
(Peer reviewed; Journal article, 2021)This paper proposes a double-heterostructure (DH) GaN/AlGaN epitaxial layer that contains an AlGaN interlayer. The electrical properties are characterized and compared with conventional single-heterostructure (SH) GaN/AlGaN ... -
Application of electrochemical methods for the detection of abiotic stress biomarkers in plants
(Peer reviewed; Journal article, 2021)Abiotic stress is the main cause of low productivity in plants. Therefore, it is important to detect stress and respond to it in a timely manner to avoid irreversible damage to plant productivity and health. The application ... -
Patterns, timing, and environmental drivers of growth in two coexisting green-stemmed Mediterranean alpine shrubs species
(Peer reviewed; Journal article, 2023)The Mediterranean alpine is one of the most vulnerable ecosystems under future environmental change. Yet, patterns, timing and environmental controls of plant growth are poorly investigated. We aimed at an improved ... -
Simulation of blue hydrogen production by natural gas in the North Sea
(Peer reviewed; Journal article, 2023)Hydrogen is an efficient energy carrier and an important contribution to sustainable energy development. Hydrogen can be produced based on different methods and on different raw materials. Blue hydrogen is hydrogen produced ... -
Simulation of Oil Recovery Through Advanced Wells Using a Transient Fully Coupled Well-Reservoir Model
(Chapter, 2023)Oil recovery can be enhanced by maximizing the well-reservoir contact using long horizontal wells. One of the main challenges of using such wells is the early breakthrough of unwanted fluids due to the heel-toe effect and ... -
Load prioritization technique to guarantee the continuous electric supply for essential loads in rural microgrids
(Peer reviewed; Journal article, 2021)Microgrid (MG) is one of the practical and best concepts to provide energy access to rural communities, where electric grid extension is not techno-economically feasible. Since the trend of load consumption is not uniform ... -
Comprehensive Local Sensitivity Analysis of the ADM1-Based Anaerobic Digestion Process
(Journal article, 2022)Anaerobic digestion is a popular method for treating waste and producing biogas. It remains challenging to automate and optimize the operation of the digester because of its complex process and suffering from great ... -
Geochemical landscapes as drivers of wildlife reproductive success: Insights from a high-Arctic ecosystem
(Peer reviewed; Journal article, 2023)The bioavailability of essential and non-essential elements in vegetation is expected to influence the performance of free-ranging terrestrial herbivores. However, attempts to relate the use of geochemical landscapes by ... -
Short-Term Production Optimization for Electric Submersible Pump Lifted Oil Field With Parametric Uncertainty
(Peer reviewed; Journal article, 2023)This paper uses a scenario-based optimization method to address the Daily Production Optimization from an Electric Submersible Pump lifted oil field under the presence of uncertainty. The primary contribution of this work ... -
A robust model predictive control with constraint modification for gas lift allocation optimization
(Peer reviewed; Journal article, 2023)This paper presents a novel approach for implementing a robust real-time optimization framework under the presence of parametric uncertainty. Conservativeness is an inevitable drawback of a robust control approach. Therefore ... -
Dataset from long-term air quality monitoring in the World Natural Heritage Geirangerfjord, Western Norway (AQM-G)
(Peer reviewed; Journal article, 2023)Here, we present a datapaper containing observational air quality and meteorological data related to our long-term air quality monitoring program at the UNESCO Natural World Heritage Site Geirangerfjord, Western Norway. ... -
Consistent imprints of elevation, soil temperature and moisture on plant and arthropod communities across two subarctic landscapes
(Peer reviewed; Journal article, 2023)1. Factors shaping arthropod and plant community structure at fine spatial scales are poorly understood. This includes microclimate, which likely plays a large role in shaping local community patterns, especially in ... -
Characterization and Validation of a Lyophilized Loop-Mediated Isothermal Amplification Method for the Detection of Esox lucius
(Peer reviewed; Journal article, 2023)In many ways, globalization is beneficial, but in one way, it promotes the spread of alien (invasive) species through international trade and transport. In different habitats, Esox lucius (northern pike) can be considered ... -
Comparative evaluation of loop-mediated isothermal amplification and PCR for detection of Esox lucius housekeeping genes for use in on-site environmental monitoring
(Peer reviewed; Journal article, 2023)Esox lucius (northern pike) is an invasive species in fresh water and causes extreme impacts in the local habitat. Northern pike easily replaces the local native species and disrupts the regional ecosystem. Traditionally, ... -
