Synchronising Wisdom and Implementation: A Formal ODD Approach to Expressing Insights on Bullying
(Doctoral Dissertations at the University of Agder;no. 441, Doctoral thesis, 2023)The Social Simulation methodology, a mix of traditionally unassociated fields, utilises computer models to describe, understand, predict, and reflect on social phenomena. The model creation process typically requires the ... -
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 ... -
Synthetic Micro-Doppler Signatures of Non-Stationary Channels for the Design of Human Activity Recognition Systems
(Doctoral Dissertations at the University of Agder; no. 333, Doctoral thesis, 2021)The main aim of this dissertation is to generate synthetic micro-Doppler signatures and TV-MDSs to train the HACs. This is achieved by developing non-stationary fixed-tofixed (F2F) indoor channel models. Such models provide ... -
