Radar-Based Passive Step Counter and Its Comparison with a Wrist-Worn Physical Activity Tracker
(Communications in Computer and Information Science (CCIS); no. 1616, Chapter; Peer reviewed, 2022)Inspired by novel applications of radio-frequency sensing in healthcare, smart homes, rehabilitation, and augmented reality, we present an FMCW radar-based passive step counter. If a person walks or performs other activities, ... -
Nye retningslinjer for syndromet relativ energimangel i idrett (REDs)
(Journal article; Peer reviewed, 2024)Lav energitilgjengelighet gir dårligere prestasjoner og flere skader. I mange idretter har utøvere et betydelig energibehov for å opprettholde effekten av nødvendig treningsmengde og ønskede konkurranseprestasjoner. Innen ... -
Optimal terminal sliding mode control for second-order motion systems
(Chapter, 2021)Terminal sliding mode (TSM) control algorithm and its non-singular refinement have been elaborated for two decades and belong, since then, to a broader class of the finite-time controllers, which are known to be robust ... -

Localization and Activity Classification of Unmanned Aerial Vehicle using mmWave FMCW Radars
(Peer reviewed; Journal article, 2021)In this article, we present a novel localization and activity classification method for aerial vehicle using mmWave frequency modulated continuous wave (FMCW) Radar. The localization and activity classification for aerial ... -
Condition Monitoring Technologies for Synthetic Fiber Ropes - a Review
(Journal article; Peer reviewed, 2017)This paper presents a review of different condition monitoring technologies for fiber ropes. Specifically, it presents an overview of the articles and patents on the subject, ranging from the early 70’s up until today with ... -
Target Classification by mmWave FMCW Radars using Machine Learning on Range-Angle Images
(Peer reviewed; Journal article, 2021)In this paper, we present a novel multiclass-target classification method for mmWave frequency modulated continuous wave (FMCW) radar operating in the frequency range of 77 - 81 GHz, based on custom range-angle heatmaps ... -
Development of a Toolbox on Sustainable ICT across Industry and Academia: The goforIT project
(Peer reviewed; Journal article, 2023)ICT plays an important role in assuring both environmental, economic, individual, technical and social sustainability. While sustainability is commonly understood at the general level, it was realized at a joint academia-industry ... -
Robust output feedback control of non-collocated low-damped oscillating load
(Chapter, 2021)For systems with order of dynamics higher than two and oscillating loads with low damping, a non-collocation of the sensing and control can deteriorate robustness of the feedback and, in worst case, even bring it to ... -
Preliminary Results on Condition Monitoring of Fiber Ropes using Automatic Width and Discrete Length Measurements
(Chapter; Peer reviewed, 2017)As the offshore sector moves to deeper waters, fiber ropes have the potential to replace more traditional solutions such as steel wire ropes for deep sea lifting and heave-compensated operations. While steel wire ropes ... -
Hybrid Position/Force Control for Hydraulic Actuators
(Chapter, 2020)In this paper a novel hybrid position/force control with autonomous switching between both control modes is introduced for hydraulic actuators. A hybrid position/force control structure with feed-forwarding, full-state ... -
Rate-Splitting Random Access Mechanism for Massive Machine Type Communications in 5G Cellular Internet-of-Things
(Chapter, 2021)The cellular Internet-of-Things has resulted in the deployment of millions of machine type communication (MTC) devices under the coverage of a single gNodeB (gNB). These massive number of devices should connect to the ... -
Stability Analysis of a Linear Parameter Varying Adaptive Output Feedback Control System
(Chapter, 2021)Output feedback control systems often require an adaptive filter for properly shaping the loop transfer function, as certain system plant parameters may be uncertain or varying. This renders the overall closed loop to a ... -
Exploring freshwater challenges for conservation efforts: Insights into threatened and invasive fish species using environmental DNA
(Doctoral dissertations at University of Agder;no. 490, Doctoral thesis, 2024)Ferskvannsøkosystemer trues av habitatendringer, menneskeskapte barrierer, fremmede arter, forurensning, overfiske og klimaendringer. Selv om internasjonale lover og forskrifter støtter bevaring, kreves det fortsatt betydelig ... -
