Impact from flexible operations on High Head Francis turbines
(Master thesis, 2018)Today the European energy grid contains more renewable energy sources than ever before, yet there is little to no research on how the increased amount affects the cost structure of the remaining energy sources of the grid. ... -
The impact of air change rate on the air quality of surgical microenvironment in an operating room with mixing ventilation
(Peer reviewed; Journal article, 2020)Transmission of airborne microbe-carrying particles (MCPs) is one of the key factors causing surgical site infection during surgical procedures. In operating rooms (ORs) with mixing ventilation, air change rate may determine ... -
Impact of Carbon Price on Renewable Energy Using Power Market System
(Chapter, 2020)Reducing anthropogenic greenhouse gas emissions is a critical element to keep global warming below 2 °C. In terms of the IEA report, the largest sources of emission in 2016, which approaches to 42% of global total, is ... -
Impact of Cooling Methods on Ageing in Lithium-ion Battery Cells
(Master thesis, 2021)At temperatur har en betydelig effekt på levetiden til Litium-ione batterier er godt dokumentert i litteraturen. Temperaturen til battericellene under bruk avhenger av egenskapene til cellene, bruken og kjølesystemet som ... -
The impact of interventions in the global land and agri-food sectors on Nature’s Contributions to People and the UN Sustainable Development Goals
(Journal article, 2020)Interlocked challenges of climate change, biodiversity loss, and land degradation require transformative interventions in the land management and food production sectors to reduce carbon emissions, strengthen adaptive ... -
The Impact of Peltier and Dufour Coefficients on Heat Fluxes and Temperature Profiles in the Polymer Electrolyte Fuel Cells
(Peer reviewed; Journal article, 2020)We show that the coupling effects in non-equilibrium thermodynamics for heat-, mass- and charge- transport in the polymer electrolyte membrane fuel cell (PEMFC) all give significant contributions to local heat effects. The ... -
Impact of powertrain electrification on CO2 emissions of the passenger light-duty vehicle fleet in Colombia
(Master thesis, 2023)This work developed a model of the passenger vehicle and two-wheelers fleet to study the potential for energy consumption and CO2 emissions reduction by powertrain electrification in the Colombian vehicle fleet from 2022 ... -
The Impact of Process Heat on the Decarbonisation Potential of Offshore Installations by Hybrid Energy Systems
(Peer reviewed; Journal article, 2021)An opportunity to decarbonise the offshore oil and gas sector lies in the integration of renewable energy sources with energy storage in a hybrid energy system (HES). Such concept enables maximising the exploitation of ... -
Impact of Recipe Design on Kinetics of Heat Pump Drying of Protein Mixtures
(Master thesis, 2012)The goals of this work are to set up and execution of experiemntal trials in order to study the influence of drying conditions and geometric parameters on quality, properties and drying kinetics using eight protein mixture ... -
Impact of Torrefaction on Woody Biomass Properties
(Journal article; Peer reviewed, 2017)In this work, Norway spruce stem wood, stump and bark were torrefied in a tubular reactor. The effects of feedstock type and torrefaction process parameters such as torrefaction temperature and residence time on the ... -
The impact of upstream turbulence on a plane jet
(Peer reviewed; Journal article, 2021)The influence of upstream turbulence on the flow produced by a plane jet is investigated experimentally with hot-wire anemometry and smoke flow visualisation. An innovative active grid, where each wing can be independently ... -
The Impact of Variable Inlet Guide Vanes on Compressor Performance
(Master thesis, 2015)Based on literature review and experimental work at the wet gas compressor rig focus is given to the inlet guide vanes performance and their impact on the impeller stage flow regime. This relates both to dry and wet operating ... -
Impact of various nanoparticles on the viscous properties of water based drilling fluids
(Chapter, 2021)Properly designed drilling fluid is a key element in achieving safe and effective drilling operations. Rheological parameters of drilling fluid determine the equivalent circulation density, the pump pressure, and hole ... -
Impacts of idealized land cover changes on climate extremes in Europe
(Peer reviewed; Journal article, 2019)Extremes in climate and weather can pose significant challenges to economy, ecosystems and human health. Changes in land cover are one of the drivers for variability in frequency and magnitude of extreme climate at regional ... -
Impacts of onshore wind energy production on birds and bats: recommendations for future life cycle impact assessment developments
(Journal article; Peer reviewed, 2018)Models for quantifying impacts on biodiversity from renewable energy technologies are lacking within life cycle impact assessment (LCIA). We aim to provide an overview of the effects of wind energy on birds and bats, with ... -
Impacts of three types of solar geoengineering on the Atlantic Meridional Overturning Circulation
(Peer reviewed; Journal article, 2022)Climate models simulate lower rates of North Atlantic heat transport under greenhouse gas climates than at present due to a reduction in the strength of the Atlantic Meridional Overturning Circulation (AMOC). Solar ... -
