Electric and magnetic signatures of boundary states in topological insulators and superconductors
Rex, Stefan (Doctoral theses at NTNU;2017:271, Doctoral thesis, 2017)This thesis is based on original research that was carried out in the field of topological phases in quantum condensed matter physics. The results have been published in five papers in Physical Review B, which form the ... -
Hydropower investment decisions. The ProdRisk-Shop simulator: decision support tool for revenue calculations
Rex, Stefan; Mo, Birger; Schäffer, Linn Emelie; Mathisen, Siri (HydroCen Rapport;45, Report, 2024)The transition to a renewable based power system induces new opportunities and challenges for hydro-power producers. In the Nordic region, reservoir hydropower is expected to play a key role in smoothing out variability ... -
Ramping Constraints in Hydropower Scheduling: With application in the SDDP-based ProdRisk model
Helseth, Arild; Rex, Stefan (HydroCen Rapport;39, Research report, 2023)Ramping constraints on water flows in hydropower systems may, e.g., ensure the preservation of ecological conditions, safely operate river systems, and prevent unfavorable ice formation. In this work we study how ramping ...
