Prognoseregulering av kjølesystemer for norske kontorbygg
(Master thesis, 2020)Denne oppgaven omtaler ulike modelleringsstrategier for prediksjon av kjølebehov for bruk av prognose modellregulering(MPC) av kjølesystemer i kontorbygg. Ved å predikere kjølebehovet er det mulig å optimalisere reguleringen ... -
Programming turbulence models in FORTRAN
(Master thesis, 2015)The two-equation turbulence models Wilcox k-omega and Menter k-omega SST are programmed in FORTRAN and tested on the cases channel flow and backward-facing step. A short time step and a good initial field is required to ... -
Project and Design of a Digital Twin for Gas Turbines for Power Generation in the Offshore Field
(Master thesis, 2023)In the global energy market, there is an increasing pressure on industries to digitise and develop efficient methods of simulating and controlling plants and components, one of the many reasons being the prediction that ... -
Promotion of hydrogen evolution from seawater via poly(aniline-co-4-nitroaniline) combined with 3D nickel nanoparticles
(Peer reviewed; Journal article, 2023)This work reports the synthesis of poly (aniline-co-4-nitroaniline) deposited on a three-dimensional nanostructured nickel (3D-Ni) film, where both layers were fabricated via potentiostatic electrodeposition. The obtained ... -
Prosjektering av måleutstyr og kompressor for luftputekammer
(Master thesis, 2016)Sauland 2 er eit elvekraftverk under prosjektering. Kraftverket planlegger å nytte luftputekammer, og som elvekraftverk er kort nedetid ved fylling av kammeret essensielt for økonomien. Luftputekammer er viktig for å ... -
Prosjektering av nytt teknisk tilbygg
(Bachelor thesis, 2023)Formålet med denne oppgaven er å prosjektere en god løsning for et teknisk tilbygg. I forbindelse med renoveringen av Garnes ungdomsskole skal det gjennomføres en oppgradering av ventilasjonssystemet i et tilknyttet ... -
Prospective Environmental Impacts of Selected Low-Carbon Electricity Technologies
(Doctoral thesis at NTNU;2015:312, Doctoral thesis, 2015)Abstract: As one of the main contributors to greenhouse gas (GHG) emissions, the global electricity production sector faces the challenge of mitigating its emissions by transitioning towards cleaner production technologies. ... -
Prospective Life Cycle Assessment of Container Shipping
(Master thesis, 2017)International shipping has lower direct CO2 emissions per unit of mass transported than any other transportation mode. However, the sector s absolute direct emissions in 2012 totalled 815 million tonnes CO2-equivalents, ... -
Prospects of using equilibrium-based column models in dynamic process simulation of post-combustion CO2 capture for coal-fired power plant
(Journal article; Peer reviewed, 2017)This paper discusses the limitations and prospects of using equilibrium-based column models for the dynamic simulation of post-combustion CO2 capture processes. Based on their features, one of three available commercial ... -
Protein kinase C activation mediates interferon-β-induced neuronal excitability changes in neocortical pyramidal neurons
(Journal article; Peer reviewed, 2014)Background Cytokines are key players in the interactions of the immune and nervous systems. Recently, we showed that such interplay is mediated by type I interferons (IFNs), which elevate the excitability of neocortical ... -
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-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 ... -
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 ... -
PV Systems on Refrigerated Warehouses
(Bachelor thesis, 2021)Despite recent years of rapid development, PV power constitutes for only 0.4 % of the total installed capacity of power production in Norway, making this an area with huge potential for expansion. Finding suitable areas ... -
PV-to-Heat: Control and Monitoring Methods
(Master thesis, 2024)Mange afrikanske land har en økende befolkning og økonomi. Imidlertid er energiproduksjonen regelmessig ikke tilstrekkelig, noe som fører til strømbrudd i byene og distriktene har ikke tilgang til strøm. Mindre enn 10 % ... -
PVTx Modeling of CO2 Pipeline at Depressurization Conditions Using SPUNG Equation of State (EoS) with a Comparison to SRK
