    • Active Compressor Surge Control System Using Piston Actuation Theory, Design, and Experiments 

      Uddin, Nur (Doctoral thesis at NTNU;2016:80, Doctoral thesis, 2016)
      This thesis presents a novel active compressor surge control system using piston actuation, and this system is called the piston-actuated active surge control system (PAASCS). This work addresses the development of PAASCS ...

    • Direct training of robots using a positional deviation sensor 

      Dessen, Fredrik (Doktor ingeniøravhandling;1988:33, Doctoral thesis, 1988)
      A device and system for physically guiding a manipulator through its task is described. The device consists of inductive, contact-free positional deviation sensors, enabling the rcbot to track a motion marker. Factors ...

    • Optimal Comfort with Limited Power 

      Rødal, Mads Dyrlid (Master thesis, 2018)
      Electricity consumption is growing and with more efficient equipment introducing larger power peaks. Reducing the power peaks can substantially reduce the electricity expenses for a building. In 2015 it was presented that ...

    • Optimizing Order to Minimize Low-Pass Filter Lag 

      Dessen, Fredrik (Journal article; Peer reviewed, 2018)
      This paper develops a tool kit for designing low-pass filters to exhibit the smallest possible phase drop. Based solely on the stopband requirements, it is thus possible to find the best order for a filter to be employed ...

    • Process Data Mining for Parameter Estimation: With the DYNIA Method 

      Fordal, Arnt Ove (Master thesis, 2010)
      Updating the model parameters of the control system of an oil and gas production system for the reasons of cost-effectiveness and production optimization, requires a data set of input and output values for the system ...

    • Wood burning habits and its effect on the electrical energy demand of a retrofitted Norwegian detached house 

      Felius, Laurina C; Thalfeldt, Martin; Georges, Laurent; Hrynyszyn, Bozena Dorota; Dessen, Fredrik; Hassan Mohamed, Mohamed Hamdy (Journal article; Peer reviewed, 2019)
      Using firewood as a space heating source is a popular solution in Norwegian housing and can significantly reduce the electrical energy demand of houses. This study analysed habits and reasons for using a wood stove from ...
