• Scaffolding open inquiry: How a teacher provides students with structure and space ﻿

(Peer reviewed; Journal article, 2015)
The present case study examines a teacher’s scaffolding strategies supporting his students during a twelve-week open inquiry project at an upper secondary school. We use interaction analysis to identify how he provides ...
• Scale size-dependent characteristics of the magnetosphere-ionosphere system using auroral imaging ﻿

(Doctoral thesis, 2017-10-06)
The spectacular and breathtaking aurora dancing around on the night sky visualizes the fundamental behavior of complex processes in the near Earth space. The plethora of papers published over the last five decades have ...
• Scale size-dependent characteristics of the nightside aurora ﻿

• Scattering from spheres and cylinders - revisited ﻿

(Conference object, 2006)
Backscattering of sound from elastic spheres is commonly applied for calibration of acoustic systems. Measurements on the "form function" of various tungsten carbide spheres turned out not to match simulations based on ...
• Scattering studies with low-energy kaon-proton femtoscopy in proton-proton collisions at the LHC ﻿

The study of the strength and behavior of the antikaon-nucleon (¯KN) interaction constitutes one of the key focuses of the strangeness sector in low-energy quantum chromodynamics (QCD). In this Letter a unique high-precision ...
• Scenario based analysis of fire escalation in a gas process plant ﻿

(Master thesis, 2013-05-28)
This study takes place on a medium sized gas process plant called reference plant. In this thesis several escalation scenarios, as well as gas dispersion, is evaluated through Kameleon KFX and Vessfire. It has previously ...
• The science case for the EISCAT_3D radar ﻿

(Peer reviewed; Journal article, 2015-07-29)
The EISCAT (European Incoherent SCATer) Scientific Association has provided versatile incoherent scatter (IS) radar facilities on the mainland of northern Scandinavia (the EISCAT UHF and VHF radar systems) and on Svalbard ...
• Scintillation and irregularities from the nightside part of a Sun-aligned polar cap arc ﻿

(Peer reviewed; Journal article, 2016-06-18)
In this paper we study the presence of irregularities and scintillation in relation to the nightside part of a long-lived, Sun-aligned transpolar arc on 15 January 2015. The arc was observed in DMSP UV and particle data ...
• Scintillation and loss of signal lock from poleward moving auroral forms in the cusp ionosphere ﻿

(Journal article, 2015-10-27)
We present two examples from the cusp ionosphere over Svalbard, where poleward moving auroral forms (PMAFs) are causing significant phase scintillation in signals from navigation satellites. The data were obtained using a ...
