Distributed Co-Simulation of Maritime Systems and Operations
Sadjina, Severin Simon; Kyllingstad, Lars Tandle; Rindarøy, Martin; Skjong, Stian; Æsøy, Vilmar; Pedersen, Eilif (Journal article, 2018)Here, we present the concept of an open virtual prototyping framework (VPF) for maritime systems and operations that enables its users to develop reusable component or subsystem models, and combine them in full-system ... -
Energy conservation and coupling error reduction in non-iterative co-simulations
Sadjina, Severin Simon; Pedersen, Eilif (Peer reviewed; Journal article, 2019)When simulators are energetically coupled in a co-simulation, coupling errors alter the total energy of the full system. This distorts system dynamics, lowers the quality of the results, and can lead to instability. Using ... -
Energy conservation and power bonds in co-simulations: non-iterative adaptive step size control and error estimation
Sadjina, Severin Simon; Kyllingstad, Lars Tandle; Skjong, Stian; Pedersen, Eilif (Journal article; Peer reviewed, 2017) -
Spin Hall effect and spin swapping in diffusive superconductors
Espedal, Camilla; Lange, Peter; Sadjina, Severin Simon; Mal'Shukov, Anatoly Germanovich; Brataas, Arne (Journal article; Peer reviewed, 2017)We consider the spin-orbit-induced spin Hall effect and spin swapping in diffusive superconductors. By employing the nonequilibrium Keldysh Green's function technique in the quasiclassical approximation, we derive coupled ...
