      Ahmed, Shady E; San, Omer; Rasheed, Adil; Trian, Iliescu (Peer reviewed; Journal article, 2021)
      Autoencoder techniques find increasingly common use in reduced order modeling as a means to create a latent space. This reduced order representation offers a modular data-driven modeling approach for nonlinear dynamical ...
    • Nonlinear State and Parameter Estimation using Discrete-Time Double Kalman Filter 

      Abdollahpouri, Mohammad; Haring, Mark; Johansen, Tor Arne; takacs, gergely; Rohal-Ilkiv, B (Journal article; Peer reviewed, 2017)
      Dealing with nonlinear dynamics in conventional estimation methods like the extended Kalman filter (EKF) is challenging, since they are not guaranteed to have global convergence, and their instability can arise by selecting ...
    • A novel hybrid analysis and modeling approach applied to aluminum electrolysis process 

      Lundby, Erlend Torje Berg; Rasheed, Adil; Gravdahl, Jan Tommy; Halvorsen, Ivar Johan (Peer reviewed; Journal article, 2021)
      Aluminum electrolysis cells are characterized by harsh environments where several measurements have to be done manually. Due to the operational costs related to manual sampling, the sampling rates of these measurements are ...

      Formålet med oppgaven var å fortsette med jobben Grindvik hadde gjort når det kommer til å skrive om Java applikasjonen til C++. Denne oppgaven inkluderte også jobben med å bruke en NRF robot for å kommunisere med den nye ...
    • nRF52 robot with OpenThread 

      Stenset, Arild (Master thesis, 2020)
      Denne oppgaven beskriver endringer gjort på roboten i detalj, hvordan de ble implementert og hvilke vurderinger som ble gjort underveis. Fra tidligere rapporter var problemer med høyre motor kjent i starten av oppgaven. ...
    • NTNU Cyborg - Teaching the Cyborg to recognize humans 

      Froknestad, Amund (Master thesis, 2017)
      Background - Several types of depth cameras exist, utilizing different principles. The camera on the cyborg, a Stereolabs ZED, uses the embedded stereo method which is mechanically simple but computationally expensive. It ...
