Pushing the limits of beam-steering lens arrays
(Journal article; Peer reviewed, 2019)An essential part of a concentrated solar power system is the solar tracker. Tracking is usually implemented by rotating the entire optical system to follow the sun, adding to the bulk and complexity of the system. ... -
The Puzzle of Project Transaction Costs - Optimising project transaction costs through client-contractor collaboration
(Doctoral theses at NTNU;2021:5, Doctoral thesis, 2021)Kostnadsoverskridelser er et gjentakende problem i bygg- og anleggsnæringen, både nasjonalt og internasjonalt. Totalkostnad i et prosjekt er summen av prosjektets produksjons- og transaksjonskostnader. Med produksjonskostnader ... -
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
(Journal article; Peer reviewed, 2014)The proper modeling of CO2 depressurization is very important for the design for safety of a pipeline. One key element of the modeling process is the thermodynamics and transport properties modeling. In this work, an ... -
pymodconn: A python package for developing modular sequence-to-sequence control-oriented deep neural networks
(Peer reviewed; Journal article, 2023)This paper introduces "pymodconn", a comprehensive python package developed for constructing modular sequence-to-sequence control-oriented deep neural networks. These deep neural networks (DNNs) are designed to predict the ... -
Pymrio – A Python Based Multi-Regional Input-Output Analysis Toolbox
(Peer reviewed; Journal article, 2021)Pymrio is an open source tool for Environmentally Extended Multi-Regional Input-Output (EE MRIO) analysis developed in Python. It provides a high-level abstraction layer for global EE MRIO databases in order to simplify ... -
Pyroksenitt Pegmatitter i Reinfjord Ultramafiske Kompleks
(Master thesis, 2020)Genesen til pyroksenitt pegmatittene i Reinfjord Ultramafiske Kompleks (RUK) er undersøkt. RUK, som utgjør en del av Seiland Magmatiske Provins (SIP), er et sjeldent eksempel på utmerket eksponering av et magmatisk ... -
Pyrolysis Kinetics and Flammability Evaluation of Rigid Polyurethane with Different Isocyanate Content
(Peer reviewed; Journal article, 2021)Polyurethane (PU) is a typical product of the reaction between isocyanate and polyol, whose ratio would greatly influence material properties. In this paper, to investigate the influence of isocyanate on PU thermal stability ... -
Pyrolysis of Untreated and Various Torrefied Stem Wood, Stump, and Bark of Norway Spruce
(Journal article; Peer reviewed, 2019)The effect of torrefaction severity (temperature and residence time) was studied on the thermal decomposition of different parts of Norway spruce (stem wood, stump, and bark). The volatile content of the torrefied samples ... -
Pyrrhotite in concrete aggregate. Introduction to mechanism, damage potential and ongoing research
(Chapter, 2022)Pyrrhotite is an iron sulfide which when present in concrete aggregate may lead to expansive reactions, cracks and finally disintegration of the concrete. This potential risk when using aggregates containing sulfides in ... -
A Python based Simulation of Industrial Scenarios - An investigation of throughput time
(Master thesis, 2018)The goal of the thesis is to find a simulation package suitable for industrial application, create a model, run simulations with it and investigate the goodness of the choice. This thesis uses the object-oriented programming ... -
