(Doctoral dissertations at University of Agder; no 485, Doctoral thesis, 2024)Reliable sensing and energy-efficient communication are an integral part of unmanned aerial vehicle (UAV)-based applications. However, it is challenging to ensure reliable sensing under all weather conditions. Furthermore, ... -
Personality of sea trout : A case study on ecology, conservation and dynamics in coastal Skagerrak
(Doctoral dissertations at University of Agder;no. 228, Doctoral thesis, 2019)Variation in fish behaviour seems to be an important part of species’ lifehistory and adaptation to environmental change. Interestingly, variation occurs not only in response to environmental cues, but can also be consistently ... -
Seascape ecology of Atlantic cod (Gadus morhua) in coastal Skagerrak: population structure, connectivity, and role in fish assemblage
(Doctoral dissertations at University of Agder;no. 294, Doctoral thesis, 2020)Atlantic cod populations along the Norwegian Skagerrak coast consist of two known ecotypes. During the last decade, there has been a dramatic decline of larger cod and other piscivorous fish species in eastern Skagerrak. ... -
Adaptive time delay based control of non-collocated oscillatory systems
(Chapter, 2024)Time delay based control, recently proposed for non-collocated fourth-order systems, has several advantages over an observer-based state-feedback compensation of the low-damped oscillations in output. In this paper, we ... -
Seasonality in phytoplankton communities and production in three Arctic fjords across a climate gradient
(Peer reviewed; Journal article, 2024)Phytoplankton communities and production in Arctic fjords undergo strong seasonal variations. Phytoplankton blooms are periods with high primary production, leading to elevated algal biomass fueling higher trophic levels. ... -
Theoretical Analysis of the Radio Map Estimation Problem
(Journal article; Peer reviewed, 2024)Radio maps provide radio frequency metrics, such as the received signal strength, at every location of a geographic area. These maps, which are estimated using a set of measurements collected at multiple positions, find a ... -
The construct of playful learning in primary mathematics: A literature overview
(Chapter; Peer reviewed, 2022)This literature overview aims to define playful learning (PL) in primary mathematics education (ME). When reading previous research literature, I discovered that early years ME researchers often do not define PL but view ... -
Spectrum Surveying: Active Radio Map Estimation with Autonomous UAVs
(Peer reviewed; Journal article, 2022)Radio maps find numerous applications in wireless communications and mobile robotics tasks, including resource allocation, interference coordination, and mission planning. Although numerous existing techniques construct ... -
