Understanding "Islandness"
(Peer reviewed; Journal article, 2023)Islandness is a contested concept, not just between disciplines but also cultures, entangled with what islands, island studies, and island identity are understood to be. The purpose of this article is to explore some of ... -
Intensified forestry as a climate mitigation measure alters surface water quality in low intensity managed forests
(Peer reviewed; Journal article, 2020)Climate change has led to a focus on forest management techniques to increase carbon (C) sequestration as a mitigation measure. Fertilisation and increased removal of biomass have been proposed. But these and other forest ... -
First record of the opal chimaera, Chimaera opalescens (Holocephali: Chimaeridae) and revision of the occurrence of the rabbitfish Chimaera monstrosa in the Azores waters
(Peer reviewed; Journal article, 2020)The presence of the opal chimaera, Chimaera opalescens, is reported for the first time in the deep waters of the Azores, with the capture of four specimens by fishermen and the video recording of an additional five ... -
Computer vision and thermal monitoring of HMPE fibre rope condition during CBOS testing
(Peer reviewed; Journal article, 2020)Fibre rope usage in deep sea lifting operations is gaining more prominence in recent times. With rope minimum break loads (MBL) comparable to that of their steel wire counterparts, the use of high modulus polyethylene ... -
Exploring Realistic Mathematics Education in a Flipped Classroom Context at the Tertiary Level
(Peer reviewed; Journal article, 2020)Flipped classroom (FC) pedagogical frameworks have recently gained considerable popularity, especially at secondary school levels. However, there are rich opportunities to explore FC at tertiary levels, but progress on the ... -
Fractional-Order Partial Cancellation of Integer-Order Poles and Zeros
(Chapter, 2022)The key idea of this contribution is the partial compensation of non-minimum phase zeros or unstable poles. Therefore the integer-order zero/pole is split into a product of fractional-order pseudo zeros/poles. The amplitude ... -
Prosessledelse og digitalisering
(Peer reviewed; Journal article, 2023)I denne artikkelen utforsker vi om det er en gjensidig sammenheng mellom prosessledelse og digitalisering. Prinsipielt handler prosessledelse om å ha kontroll med virksomhetens prosesser og forbedre dem ved behov, mens ... -
Comparison of Fractional-Order and Integer-Order H-infinity Control of a Non-Collocated Two-Mass Oscillator
(Journal article, 2022)We consider the robust control of a two-mass oscillator with a dominant input delay. Our aim is to compare a fractional-order tuning approach including the partial compensation of non-minimum phase zeros with a classical ... -
Adaptive Control of Systems with Quantization and Time Delays
(Doctoral Dissertations at the University of Agder; no. 413, Doctoral thesis, 2023)This thesis addresses problems relating to tracking control of nonlinear systems in the presence of quantization and time delays. Motivated by the importance in areas such as networked control systems (NCSs) and digital ... -
Adaptive Backstepping Attitude Control of a Rigid Body with State Quantization
(Chapter; Peer reviewed, 2021)In this paper, the attitude tracking control problem of a rigid body is investigated where the states are quantized. An adaptive backstepping based control scheme is developed and a new approach to stability analysis is ... -
Adaptive Backstepping Control of a 2-DOF Helicopter System in the Presence of Quantization
(Chapter; Peer reviewed, 2021)This paper studies the attitude tracking control for an uncertain 2-degrees of freedom helicopter system where the inputs and the states are quantized. An adaptive backstepping based control scheme is proposed to handle ... -
Probabilistic models for the fatigue resistance of welded steel joints subjected to constant amplitude loading
(Peer reviewed; Journal article, 2021)S-N curves found in various rules and regulations are the basic tool for the practicing engineer when carrying out life predictions for welded details in dynamically loaded structures. The present work is investigating the ... -
The Hierarchical Discrete Learning Automaton Suitable for Environments with Many Actions and High Accuracy Requirements
(Peer reviewed; Journal article, 2022)Since its early beginning, the paradigm of Learning Automata (LA), has attracted much interest. Over the last decades, new concepts and various improvements have been introduced to increase the LA’s speed and accuracy, ... -
Generalization of Relative Change in a Centrality Measure to Identify Vital Nodes in Complex Networks
(Peer reviewed; Journal article, 2022)Identifying vital nodes is important in disease research, spreading rumors, viral marketing, and drug development. The vital nodes in any network are used to spread information as widely as possible. Centrality measures ... -
Spectrum Sensing in Cognitive Radio Using CNN-RNN and Transfer Learning
(Peer reviewed; Journal article, 2022)Cognitive radio has been proposed to improve spectrum utilization in wireless communication. Spectrum sensing is an essential component of cognitive radio. The traditional methods of spectrum sensing are based on feature ... -
Analysis of relay-based feedback compensation of Coulomb friction
(Peer reviewed; Journal article, 2022)Standard problem of one-degree-of-freedom mechanical systems with Coulomb friction is revised for a relay-based feedback stabilization. It is recalled that a system with Coulomb friction is asymptotically stabilizable via ... -
The Gender Gap in Online Shopping in Turkey
(Peer reviewed; Journal article, 2022)The main aim of this study is to explore the gender gap in online shopping in the Turkish population. The gender gap in internet use and online shopping is investigated using the results of annual national surveys on ... -
