A graph-theoretical approach to fusing teachers' opinions about learning outcomes in higher education programmes
Guggedal, Carsten Berge (Master thesis, 2021)Et høyere utdanningsprogram kan bli modellert som en graf hvor noder kan representere fag, emner, teamer eller sub-temaer innen et program, og hvor kantene representerer potensielle relasjoner mellom dem. Slike grafer kan ... -
Calibrating range measurements of lidars using fixed landmarks in unknown positions
Alhashimi, Anas; Magnusson, Martin; Knorn, Steffi; Varagnolo, Damiano (Peer reviewed; Journal article, 2021)We consider the problem of calibrating range measurements of a Light Detection and Ranging (lidar) sensor that is dealing with the sensor nonlinearity and heteroskedastic, range-dependent, measurement error. We solved the ... -

Data-driven modeling of fatigue effects following repeated muscular contractions
Doshmanziari, Roya; Jackson, Roxanne Rose; Varagnolo, Damiano; Knorn, Steffi (Chapter, 2022)We propose a novel dynamical model for describing muscular fatigue and cramping following repeated muscular contractions in the case of female Kegel exercising. The proposed compartmental model adds opportune parameters ... -

Data-driven models of pelvic floor muscles dynamics subject to psychological and physiological stimuli
Knorn, Steffi; Varagnolo, Damiano; Dewitte, Marieke; Melles, Reinhilde (Journal article; Peer reviewed, 2019)This paper proposes individualized, dynamical and data-driven models to describe pelvic floor muscle responses in women undergoing vaginal dilation. Specifically, the models describe how the aggregated pressure exerted by ... -
A Dual Control Approach to Solve Exploration Versus Exploitation Trade-Offs in the Design of Personalized Physical Exercise Sessions
Jackson, Roxanne R.; Varagnolo, Damiano; Knorn, Steffi (Journal article; Peer reviewed, 2023)Using biofeedback in medical therapies has proven to be effective for adapting patient behaviors while keeping the patients engaged and motivated in an exercise session. This letter considers general problems in personalized ... -
Emotion Recognition from Physiological Signals Collected with a Wrist Device and Emotional Recall
Mattern, Enni; Jackson, Roxanne R.; Doshmanziari, Roya; Dewitte, Marieke; Varagnolo, Damiano; Knorn, Steffi (Peer reviewed; Journal article, 2023)Implementing affective engineering in real-life applications requires the ability to effectively recognize emotions using physiological measurements. Despite being a widely researched topic, there seems to be a lack of ... -
Graph-theoretic approaches and tools for quantitatively assessing curricula coherence
Varagnolo, Damiano; Knorn, Steffi; Staffas, Kjell; Fjällström, Eva; Wrigstad, Tobias (Peer reviewed; Journal article, 2020)In this paper, we propose a method to analyse the coherence of existing curricula at higher education institution. We focus our attention to engineering programmes at universities but the proposed method is by no means ... -
Next generation handgrip trainers
Belboe, Ole Einar Kværnsveen; Eritsland, Elias Loe; Meta, Admir (Bachelor thesis, 2023)Denne oppgaven forklarer utviklingsprosessen for en håndgrepstrener som kan samle inn målinger, loggføre data og nøyaktig beskrive grepets dynamikk. Dette betyr at den utviklede håndgrepstreneren må være i stand til å måle ... -
Quantitative analysis of curricula coherence using directed graphs
Knorn, Steffi; Varagnolo, Damiano; Staffas, Kjell; Wrigstad, Tobias; Fjällström, Eva (Journal article; Peer reviewed, 2019)This paper investigates methods for quantitatively examining the connectivity and knowledge flow in a university program considering courses and concepts included in the program. The proposed method is expected to be useful ...
