Pumping iron and manganese: Geochemistry and engineering of groundwater well systems with challenging redox conditions
(Doctoral theses at NTNU;2023:58, Doctoral thesis, 2023)Wells facilitate extraction and injection of groundwater, both for heating/cooling and drinking water purposes. Their ability to supply groundwater of sufficient quantity and quality may be impeded with time. To a large ... -
Pumping of concrete and Mortar - State of the art
(COIN Project report;5-2008, Research report, 2008)The pumpability of concrete, or its ability to move through pipes and hoses by the help of a pump while maintaining its fresh and hardened properties, can be quantified as being better the lower the necessary pressure to ... -
Punctuality development and delay explanation factors on Norwegian railways in the period 2005–2014
(Peer reviewed; Journal article, 2021)The paper revisits an investigation of delays and punctuality on Norwegian railroads from 2010, re-evaluating its findings and studying the effects of later measures put in place between 2010 and 2014. Norwegian railways ... -
Pure Mode I Fracture Toughness Determination in Rocks Using a Pseudo‑Compact Tension (pCT) Test Approach
(Journal article, 2020)Mode I fracture toughness (KIC) quantifies the ability of a material to withstand crack initiation and propagation due to tensile loads. The International Society for Rock Mechanics (ISRM) has proposed four suggested methods ... -
Purification of High-grade Calcite Ore by Flotation with Alkyl Diamines
(Peer reviewed; Journal article, 2018)A very high-grade calcite deposit located in northern Norway consists of CaCO3 ore with minor silicate and sulphide impurities. Cationic (Tallow-1,3-diaminopropane, Duomeen T) collector has been used in the purification ... -
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 ... -
