Peer learning and concept test, Formative assessment a learning opportunity
(Chapter, 2019)The experiences and conceptions about the physical world that students bring into the classroom may support or inhibit them in gaining an understanding congruent with the physical theories. This is relevant for classical ... -
Perceptions of technology education:: a cross-case study of teachers realising technology as a new subject of teaching
(Doctoral thesis, 2003)Education has become internationalised. Educational trends, concerns and debates exceed national and cultural borders, and ideas and innovations are being exchanged and transferred. Many curriculum programmes and reforms ... -
Perfect depolarization in single scattering of light from uncorrelated surface and volume disorder
(Journal article, 2020)-polarized waves from uncorrelated surface and volume disorder can lead to perfect depolarization. The degree of polarization vanishes in specific scattering directions that can be characterized based on simple geometric ... -
Performance analysis of heat and energy recovery ventilators using exergy analysis and nonequilibrium thermodynamics
(Journal article; Peer reviewed, 2018)The increased attention to energy savings has contributed to more widespread use of energy recovery systems for building ventilation. We investigate the efficiency of such systems under different outdoor conditions using ... -
Performance of neural networks in search for a new dark matter aware gauge boson Z' in final states with leptons and missing transverse energy atthe LHC with the ATLAS detector
(Master thesis, 2023)Vi gjennomfører et søk etter et nytt gaugeboson Z' i sluttilstander med to leptoner og manglende transversal energi. Søket er basert på hypotetiske mørk Higgs-modeller og "light vector"-modeller. Data generert av ... -
Periapsis precession of all viable planets
(Bachelor thesis, 2024)Generell relativitetsteori er i forkant av moderne fysikk. Flere tester på teorien er høyt verdsatt, for a skyve fysikkens grenser. Ett spesifikt felt dette kan anvendes på er periapsis presesjon av planeter. Denne oppgaven ... -
Permeability, Growth and Morphology of Coastal Ice - Site Study in Van Mijenfjorden, Svalbard
(Master thesis, 2015)Coastal ice includes the parts of the sea ice that are stressed and deformed by tidal motion; the ice foot (the inner part that is frozen to the ground) and the hinge zone (the zone where cracking occurs due to tidal ... -
A Perturbation Analysis Approach for Studying the Effect of Swelling Kinetics on Instabilities in Hydrogel Plates
(Journal article; Peer reviewed, 2021)The onset of surface instability during diffusion-driven swelling of hydrogels depends on the kinetics of the swelling process. Here, we outline a perturbation analysis framework using a finite difference approach for ... -
pH-dependent complexation of polyelectrolytes and spherical nanoparticles
(Doctoral theses at NTNU;2019:270, Doctoral thesis, 2019)The adsorption and desorption of polyelectrolytes (PEs) on other macromolecules are utilized in a number of different industries and biological applications. Electrostatic interactions are important in these systems, and ... -
pH-Dependent Polyelectrolyte Bridging of Charged Nanoparticles
(Journal article; Peer reviewed, 2018)Systems comprised of polyelectrolytes and charged nanoparticles are of great technological interest, being common components in formulations among other uses. The colloidal stability of formulations is an important issue, ... -
Phase diagram of an extended Kane-Mele-Hubbard model in strongly correlated regime
(Master thesis, 2020)Hovedformålet med denne masteroppgaven er å se på en utvidet Kane-Mele-Hubbard-modell i sterkt korrelerende regime fra referansen [Juan M. Losada, 2019], der både anisotropi- og Dzyaloshinskii-Moriya-vekselvirkninger (DMV) ... -
Phase perturbative calculations of diffuse light scattering on randomly rough surfaces in and out of plane
(Master thesis, 2021)Ved en eller annen lendgdeskala viser alle overflater en grad av ruhet, og det er viktig å forstå de fysiske konsekvensene av det. Denne oppgaven handler om refleksjon av elekromagnetiske bølger i det optiske bølgelengderegimet ... -
Phase separation and orientational ordering of synthetic Na-fluorohectorite clay particles in saline aqueous suspensions
