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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
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. ... -
Annual ring width in the arctic-alpine dwarf-shrub species Salix herbacea - dataset from long-term alpine ecosystem research in central Norway (Ltaer-no)
(Peer reviewed; Journal article, 2023)Here we present a datapaper containing microscopically measured data of annual ring widths in the arctic-alpine dwarf-shrub species Salix herbacea (central Norway). The dataset will be updated with future measurements. -
Enhanced demand side management for solar-based isolated microgrid system: Load prioritisation and energy optimisation
(Peer reviewed; Journal article, 2023)A novel control mechanism is presented for rural microgrids, standing out in the current literature with its advanced approach to load prioritisation and energy allocation. The system's main goal is to maximise energy ... -
Improved Crystallinity of Annealed 0002 AlN Films on Sapphire Substrate
(Peer reviewed; Journal article, 2023)AlN is a piezoelectric material used in telecommunication applications due to its high surface acoustic wave (SAW) velocity, stability, and mechanical strength. Its performance is linked to film quality, and one method to ... -
Power Sharing in Three-Level NPC Inverter Based Three-Phase Four-Wire Islanding Microgrids With Unbalanced Loads
(Peer reviewed; Journal article, 2023)The droop-based control schemes are widely used for power-sharing and control of the isolated microgrids. The conventional droop control scheme with inner current and voltage controllers can work effectively under ideal ... -
Autoethnography in Management Research: Possibilities and Pitfalls in a Research Case on Public Management Decision-Making
(Journal article, 2023)Autoethnography is usually associated with cultural, identity-related or postcolonial studies, not with managerial decision-making and communications. This research project used self-reported diaries on decision-process ... -
Design-based system performance assessment of a combined power and freshwater cogeneration system
(Peer reviewed; Journal article, 2023)In this research, the design and use of combined systems for the simultaneous production of water, heat, and energy have been proposed, and, to fulfill the water, electricity, and heat demands of a hotel, modeling of the ... -
Language aptitude and its links with metalinguistic knowledge, self-efficacy, anxiety, and language maintenance in multilingual language teachers
(Peer reviewed; Journal article, 2024)Language teachers cannot help their students develop high levels of metalinguistic knowledge and language aptitude if they themselves are found lacking in these abilities. This article reports on a study that utilised a ... -
Sliding Mode Controller Applied to Autonomous UAV Operation in Marine Small Cargo Transport
(Peer reviewed; Journal article, 2023)Unmanned aerial vehicles (UAVs) have been used in different applications due to their flexibility in maneuvering and performing missions. However, they can face external disturbances, such as wind, which can cause physical ... -
