Heating and Ventilation of Highly Energy Efficient Residential Buildings: Environmental Assessment of Technology Alternatives
(Master thesis, 2011)The aim of this study was to determine the level of environmental impact and primary energy resulting from demands placed on residential ventilation and heating systems; a conventional residential house built to the 2007 ... -
Heating New Anodes Using the Waste Heat of Anode Butts: Establishing the Interface Thermal Contact Resistance
(Peer reviewed; Journal article, 2021)In order to be able to assess the rate of heat transfer between a new anode and an anode butt, it is critical to measure the interface thermal contact resistance between them. For that purpose, a lab experiment has been ... -
Heating performance enhancement of a new design trombe wall using rectangular thermal fin arrays: An experimental approach
(Journal article; Peer reviewed, 2019)It has been nowadays recognized that addressing energy use in buildings can reduce the fossil fuels usage and CO2 emission. Trombe wall is a widely applicable passive solar design option that can significantly reduce the ... -
Heating power at room and building levels in passive houses and low-energy buildings
(Master thesis, 2015)This master thesis investigates the Norwegian standard for calculating necessary power demand, NS-EN 12831:2003- Varmesystemer i bygninger - Metode for beregning av dimensjonerende effektbehov. In that context, it is also ... -
Heating system performance estimation using optimization tool and BEMS data
(Journal article, 2008)Causes and effects of a few real faults in a hydronic heating system are explained in this paper. Since building energy management system (BEMS) has to be utilized in fault detection and diagnosis (FDD), practical explanations ... -
Heave Compensated Managed Pressure Drilling: Lab Experiments
(Master thesis, 2013)The world energy demand is ever increasing with every year. Oil and gas make up approximately 55% of energy sources to meet the demand. However, hydrocarbons reserves are limited and according to peak oil theory, the peak ... -
Heave Compensated Tripping
(Master thesis, 2019)Olje- og gassindustrien blir møtt med store utfordringer når nye brønner skal bores fra flytende plattformer. En av disse utfordringene er trykkvariasjoner i brønnen forårsaket av bevegelse av boreutstyret. Siden havbølger ... -
Heave disturbance attenuation in managed pressure drilling from a floating platform using model predictive control
(Master thesis, 2014)Since a large part of the Norwegian oil shelf has been active for over a generation, many fields begin to be depleted and the drilling operations requires tight down hole pressure margins. And by improving the pressure ... -
Heave Motion Estimation on a Craft Using a Strapdown Inertial Measurement Unit
(Journal article; Peer reviewed, 2013)This paper deals with heave position and heave velocity estimation on a craft. The estimation is done without any knowledge of the specified craft. An accurate estimation of these signals is useful when one wants to control ... -
HeaveLock - A New System For Reduced Surge And Swab Pressure For Floating Drilling Operations
(Master thesis, 2016)Managed pressure drilling is only carried out from fixed installation in harsh environments today. Rig heave is compensated with top drive compensation system under drilling or tripping of pipe. During connections the ... -
HeaveLock - Enabling MPD On Floating Drilling Vessels
(Master thesis, 2016)During drilling operations from floating drilling vessels, it is often experienced challenges related to heave motions when the rig s heave compensating system is deactivated. Rig heave movements cause the bottom hole ... -
Heavier smoking increases coffee consumption: findings from a Mendelian randomization analysis
(Journal article; Peer reviewed, 2017)Background There is evidence for a positive relationship between cigarette and coffee consumption in smokers. Cigarette smoke increases metabolism of caffeine, so this may represent a causal effect of smoking on caffeine ... -
