Pulsed Laser Deposited TiO2: X-Ray Diffraction and Raman Spectroscopy Studies
(Master thesis, 2022)Pulserende laserdeponerte TiO2-tynnfilmer har blitt undersøkt ved røntgen-diffraksjon (XRD) og ramanspektroskopi. Utvalget av TiO2-tynnfilmer bestod av både udopede og (Cr,N)-dopede filmer. Bakgrunnen for studien var å ... -
Pulsed Laser Deposition of Zinc Sulfide Thin Films on Silicon: The influence of substrate orientation and preparation on thin film morphology and texture
(Master thesis, 2014)The effect of orientation and preparation of silicon substrates on the growth morphology and crystalline structure of ZnS thin films deposited by pulsed laser deposition (PLD) has been investigated through scanning electron ... -
Pulsed Laser Deposition of ZnO Nanostructures for Hybrid Inorganic/Organic Solar Cells
(Master thesis, 2009)Au catalyst ZnO nanostructures have been grown on the a- and c-plane sapphire substrate by PLD. Influence of substrate lattice orientation, substrate surface and different substrate annealing temperature have been characterized ... -
Pulsed laser growth of La2NiMnO6 for intermediate band solar cells
(Master thesis, 2022)Mellombåndssolceller har vist stort potensiale for å øke effektiviteten til fotoelektriske enheter, og samtidig redusere kostnaden knyttet til produsert elektrisitet. Funksjonelle oksidmaterialer, som doble perovskitter, ... -

Pulseless electrical activity in in-hospital cardiac arrest – A crossroad for decisions
(Journal article; Peer reviewed, 2022) -
Pulseless electrical activity in patients with in-hospital cardiac arrest
(Doctoral theses at NTNU;2023:337, Doctoral thesis, 2023)Cardiac arrest is often divided into a shockable and a non-shockable type according to effective treatment. Patients with shockable rhythms may regain pulse after an electric shock and have significantly better survival ... -
Pump as Turbine - Symmetry Prediction Method for Pump as Turbine Characteristics
(Master thesis, 2018)As a cheap and available source of renewable energy, regular centrifugal pumps may be run in reverse to act as hydro turbines. Pumps as turbines (PAT) are especially relevant for isolated rural areas, or in developing ... -

Pump turbines in existing powerplants
(Master thesis, 2019)En brukervennlig metode for å designe kontraroterende aksialpumper har blitt utviklet ved bruk av Matlab. Grafiske brukergrensesnitt har blitt laget for å skrive inn designparametre og å vise designresultater. Designmetoden ... -
Pump-probe experiments of multicrystalline silicon for solar cell applications
(Master thesis, 2012)In order to make cost effective solar cells from mc-Si materials, the negative contributions from defects and impurities should be reduced. The analysis of the photogenerated carrier properties is therefore of great ... -
Pump-Turbines in Conventional Hydropower Plants
(Peer reviewed; Journal article, 2021)This paper proposes an innovative approach to retrofit existing hydropower plants with suitable upper and lower reservoirs into pumped storage. The conventional methods are both comprehensive and expensive, mainly due to ... -
Pumpe- og turbinkarakteristikker i fire kvadranter
(Master thesis, 2014)Reversible pumpeturbiner blir i økende grad brukt for å balansere kraftproduksjonen. Den økte bruken av reversible pumpeturbiner gjør også at det er nødvendig med bedre kjennskap til hvordan maskinen oppfører seg i uønskede ... -
Pumpe-og effektkraftverk i Nordfjord
(Master thesis, 2012)Den nordiske kraftmarknaden er i endring, mellom anna som følgje av utbygging av mykje uregulert produksjon i Noreg og Europa. Uregulert produksjon må balanserast, og Noreg har reguleringsmagasin som kan nyttast til formålet. ... -
Pumped Storage Development in Øvre Otra, Norway
(Master thesis, 2012)The objective with this thesis was to describe the challenges related to PSH, both for this particular study and in more general terms.The method used was to make assumptions that would apply to traditional hydropower and ... -
Pumpekraftverk for effektproduksjon
(Master thesis, 2008)Europa har et stadig økende energiforbruk, og har samtidig mål om å redusere bruken av fossile brensel. De termiske kraftverkene er trege å regulere, og et økende innslag av vindkraft forsterker en allerede vanskelig ... -
PUMPEKRAFTVERK MELLOM STORE UREVATNET OG VATNDALSVATNET I ØVRE OTRA - TUNNELSYSTEM
(Master thesis, 2012)EU har planer for en storstilt utbygging av uregulerbar kraft, og etterspør regulerbar kraft som kan balansere forskjellen mellom kraftforbruk og kraftproduksjon. Norge har et fleksibelt vannkraftsystem, og kan bli en ...
