• Controller Motifs for Homeostatic Regulation and Their Applications in Biological Systems 

      Thorsen, Kristian (PhD thesis UiS;276, Doctoral thesis, 2015-12-03)
      Living organisms have over billions of years evolved into highly specific and complex entities. Although the range of organisms that inhabit our planet is strikingly diverse, they are all in some extent able to protect ...
    • Development, analysis and simulation of a model for cancer cell metabolism 

      Stokka, Svein Håvard (Masteroppgave/UIS-TN-IDE/2019;, Master thesis, 2019-07-14)
      In this thesis a dynamic model for cancer cell metabolism was investigated and analysed. The model describe two cellular conditions common in cancer cell metabolism; aerobic glycolysis, a condition where cells increased ...
    • Estimering av ladestatus i en elektrisk racerbil med bruk av Kalmanfilter 

      Tjørhom, Raymond (Masteroppgave/UIS-TN-IDE/2020;, Master thesis, 2020)
      Denne oppgaven er skrevet i samarbeid med ION Racing, en studentorganisasjon ved Universitetet i Stavanger som hvert år bygger en elektrisk racerbil. Oppgaven dreier seg om ferdigstillelse av et batteriovervåkningssystem ...
    • Homeostatic controllers compensating for growth and perturbations 

      Ruoff, Peter; Agafonov, Oleg; Tveit, Daniel Myklatun; Thorsen, Kristian; Drengstig, Tormod (Journal article; Peer reviewed, 2019-08)
      Cells and organisms have developed homeostatic mechanisms which protect them against a changing environment. How growth and homeostasis interact is still not well understood, but of increasing interest to the molecular and ...
    • Implementering av et Volterra prefilter i en klasse-D forsterker 

      Jensen, Christoffer Johansen (Masteroppgave/UIS-TN-IDE/2017;, Master thesis, 2017-06)
      Målet med denne oppgaven er å foreta en digital filtrering av et musikksignal, og deretter implementere digital konvertering av dette signalet til et pulsbreddemodulert signal. Det endelige målet med prosjektet, som denne ...
    • Structural Properties of Biological Integral Feedback Motifs 

      Tveit, Daniel Myklatun (PhD thesis UiS;, Doctoral thesis, 2020-09)
      Cells are exposed to a range of external and internal disturbances that may influence the function of cellular processes. The ability of cells to self-regulate and adapt to disturbances enable them to maintain essential ...
    • A systems biology approach to cellular homeostasis, volume changes and regulation of metabolism 

      Fjeld, Gunhild (PhD thesis UiS;509, Doctoral thesis, 2020-04)
      Cells need to respond to a vast range of different disturbances and changes over small and large time scales. This can be disturbances in the form of molecules used to fight infectious states, changes in growth patterns, ...
    • The organization of controller motifs leading to robust plant iron homeostasis 

      Agafonov, Oleg; Selstø, Christina Helen; Thorsen, Kristian; Xiang, Ming Xu; Drengstig, Tormod; Ruoff, Peter (Journal article; Peer reviewed, 2016-01)
      Iron is an essential element needed by all organisms for growth and development. Because iron becomes toxic at higher concentrations iron is under homeostatic control. Plants face also the problem that iron in the soil is ...
    • Variable setpoint as a relaxing component in physiological control 

      Risvoll, Geir; Thorsen, Kristian; Ruoff, Peter; Drengstig, Tormod (Journal article; Peer reviewed, 2017-09)
      Setpoints in physiology have been a puzzle for decades, and especially the notion of fixed or variable setpoints have received much attention. In this paper, we show how previously presented homeostatic controller motifs, ...
