Ultra-Low Power Wake-up Radio for 5G IoT
(Journal article; Peer reviewed, 2019)5G Internet of Things (5G IoT), which is currently under development by 3GPP, paves the way for connecting diverse categories of devices to the IoT via cellular networks. For battery-powered low-cost IoT devices, wake-up ... -
Development of Point-to-Point Path Control in Actuator Space for Hydraulic Knuckle Boom Crane
(Journal article; Peer reviewed, 2020) -
Synthetic Esters in Hydraulic Valves
(Doctoral Dissertation at the University of Agder; no. 277, Doctoral thesis, 2020)Each year 35-37 million tons of lubrication is consumed. Hydraulic oils constitute 10.2% of the total lubrication consumption, and a large part of that is lost to leakage, hose burst and accidents. One way of reducing the ... -
Banach spaces where convex combinations of relatively weakly open subsets of the unit ball are relatively weakly open
(Journal article; Peer reviewed, 2020) -
Mathematical Modelling and Analysis of Vehicle Frontal Crash using Lumped Parameters Models
(Doctoral Dissertation at the University of Agder; no. 261, Doctoral thesis, 2020)A full-scale crash test is conventionally used for vehicle crashworthiness analysis. However, this approach is expensive and time-consuming. Vehicle crash reconstructions using different numerical modelling approaches can ... -
Identifying the combinations of motivations and emotions for creating satisfied users in SNSs : An fsQCA approach
(Journal article; Peer reviewed, 2020) -
Student meaning making in elementary algebra teaching : An in-depth study of classrooms in four countries
(Doctoral dissertations at the University of Agder; no. 258, Doctoral thesis, 2020)The research presented in this thesis is based on observations and analyses of classroom data from four countries. The data were collected through a collaboration of local research teams in Finland, Norway, Sweden and the ... -

A Case Study of Technology Use and Information Flow at a Danish E-clinic
(Chapter; Peer reviewed, 2020)There is an urgent call from health organizations, health professionals and health authorities to re-design care delivery for patients with chronic conditions and multimorbidities. The research project 3P- Patients and ... -
Towards Thompson Sampling for Complex Bayesian Reasoning
(Doctoral Dissertation at the University of Agder; no. 275, Doctoral thesis, 2020)Thompson Sampling (TS) is a state-of-art algorithm for bandit problems set in a Bayesian framework. Both the theoretical foundation and the empirical efficiency of TS is wellexplored for plain bandit problems. However, the ... -
Hybrid modeling and control of mechatronic systems using a piecewise affine dynamics approach
(Doctoral Dissertation at the University of Agder; no. 273, Doctoral thesis, 2020)This thesis investigates the topic of modeling and control of PWA systems based on two experimental cases of an electrical and hydraulic nature with varying complexity that were also built, instrumented and evaluated. A ... -
On stability of linear dynamic systems with hysteresis feedback
(Journal article; Peer reviewed, 2020)Abstract. The stability of linear dynamic systems with hysteresis in feedback is considered. While the absolute stability for memoryless nonlinearities (known as Lure’s problem) can be proved by the well-known circle ... -

An exploration of teaching and learning activities in mathematics flipped classrooms : A case study in an engineering program
(Doctoral Dissertations at the University of Agder; no. 271, Doctoral thesis, 2020)This research project is a case-study of three consecutive cohorts of engineering students being subject to the pedagogical approach of flipped classroom (Bergmann & Sams, 2012). The study, which is qualitative and based ... -
Condition Monitoring Methods for Large, Low-speed Bearings
(Doctoral Dissertations at the University of Agder; no. 260, Doctoral thesis, 2020)In all industrial production plants, well-functioning machines and systems are required for sustained and safe operation. However, asset performance degrades over time and may lead to reduced effiency, poor product quality, ... -
