Meal detection based on non-individualized moving horizon estimation and classification
Kölle, Konstanze; Fougner, Anders Lyngvi; Stavdahl, Øyvind (Journal article, 2017)Meals are one of the greatest challenges to glucose regulation in diabetes mellitus type 1. Several times each day, food causes heavily elevated blood glucose concentrations that may result in long-term complications. ... -
Meal estimation from Continuous Glucose Monitor data using Kalman filtering and hypothesis testing
Staal, Odd Martin; Sælid, Steinar; Fougner, Anders Lyngvi; Stavdahl, Øyvind (Journal article; Peer reviewed, 2019)A method for estimating meal inputs from Continuous Glucose Monitoring (CGM) data is presented. The method is based on Kalman filtering and hypothesis testing, and provides estimates of the time the meal was initiated and ... -
Mechanisms controlling human head stabilization during random rotational perturbations in the horizontal plane revisited
Stensdotter, Ann-Katrin; Pedersen, Morten Dinhoff; Meisingset, Ingebrigt; Vasseljen, Ottar; Stavdahl, Øyvind (Journal article; Peer reviewed, 2016)This study repeats the experimental protocol for investigation of head stabilization in healthy humans, described by Keshner and Peterson (1995) but with a modification of the analysis. Head movements were considered with ... -
Mechanisms of sporadic control failure related to the skin-electrode interface in myoelectric hand prostheses
Stavdahl, Øyvind; Terje, Mugaas; Ottermo, Maria Vatshaug; Magne, Tordis; Kyberd, Peter Joseph (Journal article; Peer reviewed, 2019)Introduction This study is concerned with the control of hand prostheses based on electromyograms. As the prosthesis is moved in space, the socket and electrodes can shift on the residual limb, causing changes in the ... -
Mekanoelektrisk respons i overflate-EMG-målinger
Farstad, Simen Andreas (Master thesis, 2009)Det er blitt utviklet en elektrode for samtidig måling av overflateelektromyografi og kontaktkraften mellom elektroden og huden. Forsøk er gjort med kontraksjon av flexor carpi radialis samtidig som ekstern kraft er påført ... -
Methods for fault detection in an artificial pancreas
Unstad, Karl Arthur Frelsøy (Master thesis, 2018)This thesis is concerned with research related to diabetes treatment, and more specifically with treatment methods via artificial pancreas. A fault detection system is developed and implemented in the APT-simulator. The ... -
Modeling for Hybrid Obstacle-Aided Locomotion (HOAL) of Snake Robots
Gravdahl, Irja; Stavdahl, Øyvind; Koushan, Atussa; Løwer, Jostein; Pettersen, Kristin Ytterstad (Peer reviewed; Journal article, 2022)Snake robots able to operate in cluttered environments will be fit for a multitude of applications pertinent for society such as search-and-rescue operations, fire fighting and traversing otherwise unavailable tight spaces. ... -
Modeling movement-induced errors in AC electromagnetic trackers
Tuffaha, Mutaz; Stavdahl, Øyvind; Stensdotter, Ann-Katrin (Peer reviewed; Journal article, 2020)Error analysis of electromagnetic motion tracking systems is of growing interest to many researchers. Under sensor movement, it is logical to presume that the error in position and orientation measurements will increase. ... -
Modelling and control of obstacle-aided snake robot locomotion based on jam resolution
Liljeback, Pål; Pettersen, Kristin Ytterstad; Stavdahl, Øyvind (Journal article; Peer reviewed, 2009)A snake robot can traverse cluttered and irregular environments by using irregularities around its body as push-points to aid the propulsion. This characteristic feature of snake locomotion, denoted obstacle-aided locomotion, ... -
