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
(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 ... -
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 ... -
Quality Characterization and Modeling Experimental Kinetics in Pilot Scale Heat Pump Drying of Green Peas
(Master thesis, 2013)Drying is one of the most necessary process and technology in today?s world and it is used, among other things, for food processing. The basic goal is to process the food for consumption by increasing its shelf life, and ... -
Quality of fresh foods
(Doktoravhandlinger ved NTNU, 1503-8181; 137, Doctoral thesis, 2002)During the last few years the trend in food trade has moved rapidly from frozen to fresh products. Problems with temperature control in the processing and the distribution of fresh foods have at the same time been well ... -
Quantifying biodiversity impacts of hydropower electricity production within the framework of Life Cycle Assessment
(Doctoral theses at NTNU;2019:161, Doctoral thesis, 2019)The United Nations developed 17 Sustainable Development Goals (SDGs) for the transition into a more sustainable world. One of the central aspects of the SDGs is the provisioning of sustainable energy, covered by SDG 7 ... -
Quantifying energy demand and greenhouse gas emissions of road infrastructure projects: An LCA case study of the Oslo fjord crossing in Norway.
(Journal article; Peer reviewed, 2016)The road sector consumes large amounts of materials and energy and produces large quantities of greenhouse gas emissions, which canbe reduced with correct information in the early planning stages of road ... -
Quantifying entanglement impacts from lost fishing gear
(Master thesis, 2022)Plast fortsetter å akkumulere i havet på grunn av mangelfulle avfallshåndteringssystemer og direkte deponering eller tap i havet. Plast i det marine miljøet er kjent for å forårsake påvirkninger som innvikling og inntak ... -
Quantifying environmental impacts of river fragmentation from hydropower dams within Life Cycle Impact Assessment
(Master thesis, 2023)Økende produksjon av vannkraft er en av måtene å redusere menneskeskapte klimagassutslippene i årene som kommer, for å begrense klimaendringer. Imidlertid utgjør driften av vannkraftmagasiner en trussel mot ferskvannshabitater ... -
Quantifying Europe's biodiversity footprints and the role of urbanization and income
(Journal article; Peer reviewed, 2020)Biodiversity footprinting links consumers to the biodiversity pressure their consumption induces, thereby informing choices and enabling participation in remediation measures. In order for countries, cities and households ... -
Quantifying global habitat loss impacts from roads in a LCA context.
(Master thesis, 2023)Roads are one of the major causes of biodiversity loss. It is estimated that millions of animals die annually due to vehicle collisions. Furthermore, roads can induce habitat fragmentation, pollution, disturbance, and ... -
Quantifying net water consumption of Norwegian hydropower reservoirs and related aquatic biodiversity impacts in Life Cycle Assessment
(Journal article; Peer reviewed, 2019)Compared to conventional energy technologies, hydropower has the lowest carbon emissions per kWh. Therefore, hydropower electricity production can contribute to combat climate change challenges. However, hydropower electricity ... -
Quantifying the climate response to extreme land cover changes in Europe with a regional model
(Journal article; Peer reviewed, 2018)Many future scenarios expect a key role for the land use sector to stabilize temperature rise to 2 °C or less. Changes in land cover can influence the climate system, and the extent and magnitude of the anthropogenic ... -
