Experiment Design Considerations for Estimating Energy Expenditure during Wheelchair Propulsion
Doshmanziari, Roya; Aandahl, Håkon Strand; Danielsson, Marius Lyng; Baumgart, Julia Kathrin; Varagnolo, Damiano (Chapter, 2023)We propose a methodology for estimating energy expenditure (EE) during wheelchair propulsion. The method is based on measured physiological and kinematic signals from wearable sensor devices in an experimental setup design. ... -
Experimental assessment of a JANUS-based consensus protocol
Wengle, Johan Emil Hugo; Erstorp, Elias Strandell; Lidström, Viktor; Varagnolo, Damiano; Dong, Hefeng (Journal article; Peer reviewed, 2024)This paper proposes a distributed, JANUS-based protocol that enables an underwater acoustic network to reach consensus on arbitrary local opinions as numeric state variables. An envisioned scenario where nodes shall agree ... -
Exploring Frequency, Variability and Propulsion Patterns in Manual Wheelchair Propulsion
Reierstad, Håvard Pettersen (Master thesis, 2023)Teknologiske fremskritt i de siste årene har gjort det mulig å ta i bruk ulike sensorer for aktivitets- og treningsmåling. De fleste av disse enhetene er hovedsakelig beregnet for personer uten funksjonsnedsettelser, og ... -
Form Closure For Fully Actuated and Robust Obstacle-Aided locomotion in Snake Robots
Løwer, Jostein; Gravdahl, Irja; Varagnolo, Damiano; Stavdahl, Øyvind (Peer reviewed; Journal article, 2023)In this letter we adapt the theory of form closure to define the form closed region: The subset of a snake robot's configuration space for which the constraints imposed by the obstacles in its environment render the system ... -
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 ... -
Implementation and Comparison of Nonlinear State of Charge Estimators using Equivalent Circuit Models for Two Lithium-Ion Battery Cell Chemistries
Svendsen, Daniel Dreyer (Master thesis, 2023)Litium-ion-batterier blir omfattende brukt som en energilagringsløsning. De gir fordeler som lav vekt, høy energitetthet og holdbarhet, og kan være avgjørende for ̊a oppn ̊a kli- manøytralitet. Kontinuerlig optimalisering ... -
Improved Jacobian matrix estimation applied to snake robots
Løwer, Jostein; Varagnolo, Damiano; Stavdahl, Øyvind (Peer reviewed; Journal article, 2023)Two manipulator Jacobian matrix estimators for constrained planar snake robots are developed and tested, which enables the implementation of Jacobian-based obstacle-aided locomotion (OAL) control schemes. These schemes use ... -
Incremental Self-Deployment of Multi-Agent Networks in Unknown Environments
