Greenhouse Gas Reduction Potential in Norwegian Coastal Shipping: A Well-to-Wake Analysis of Alternative Shipping Fuels
(Master thesis, 2023)Klimaendringer gjør det nødvendig å redusere klimagassutslipp i alle sektorer, også innen skipsfart. En foreslått løsning for å redusere utslippene er å erstatte dagens fossile drivstoff med lav- eller nullutslipps-alternativer. ... -
Greenland ice mass balance using GRACE gravity data
(Master thesis, 2014)The mass balance of Greenland has been assessed with data from the Gravity Recovery and Climate Experiment (GRACE) satellite mission. Monthly data has been used through the time span of the study; January 2003 - December ... -
Greenland ice-melt spread into Northwest Coast revealed by GRACE (GRACE data viser at issmeltingen på Grønland sprer seg til nordvestkysten)
(Peer reviewed; Journal article, 2012)We examine the extent and magnitude of Greenland ice sheet surface melting between 2002 and 2010. We show that the well documented Greenland ice mass loss in the southern region spread to northwest Greenland in the period ... -
Greenland mass balance estimation from satellite gravity measurements
(Peer reviewed; Journal article, 2010)The Gravity Recovery and Climate Experiment (GRACE) data is used to estimate the secular trend and periodic variations of ice mass variability over Greenland. To do this, we use 92 monthly GRACE level 2 Release-04 (RL04) ... -
Gresskledde vannveger i norsk klima
(Master thesis, 2013)Gresskledde vannveger er et tiltak for åpen overvannshåndtering. Hovedmålet med denne oppgaven er å øke kunnskapen om planlegging og utforming av gresskledde vannveger i Norge. Gresskledde vannveger er en grunn forsenking ... -
Grey-box modeling of the building thermal dynamics for MPC applications: The case of residential space-heating
(Doctoral theses at NTNU;2022:324, Doctoral thesis, 2022)The transition from a conventional energy system to a decarbonized energy system requires an increasing penetration of intermittent renewable energy sources, which brings more fluctuations to the electricity grid. Therefore, ... -
Grid independence behaviour of fluidized bed reactor simulations using the Two Fluid Model: Detailed parametric study
(Journal article; Peer reviewed, 2016)This short communication builds on previous work on the grid independence behaviour of the Two Fluid Model in reactive bubbling fluidized bed simulations. Regarding hydrodynamic grid independence behaviour (the numerical ... -
Grid independence behaviour of fluidized bed reactor simulations using the Two Fluid Model: Effect of particle size
(Journal article; Peer reviewed, 2014)It is well known that particle size has a significant influence on the grid independence behaviour of fluidized bed reactor simulations carried out using the Two Fluid Model (TFM) approach. The general rule of thumb states ... -
A Grid-Based Approach for Measuring Similarities of Taxi Trajectories
(Peer reviewed; Journal article, 2020)Similarity measurement is one of the key tasks in spatial data analysis. It has a great impact on applications i.e., position prediction, mining and analysis of social behavior pattern. Existing methods mainly focus on the ... -
Grid-independent Eulerian-Lagrangian approaches for simulations of solid fuel particle combustion
(Journal article; Peer reviewed, 2020)In this study, a computational fluid dynamics (CFD) model with three coarse graining algorithms is developed with the implementation of a layer based thermally thick particle model. Three additional coupling methods, cube ... -
Gridshells in Recent Research—A Systematic Mapping Study
(Peer reviewed; Journal article, 2021)Gridshells are shells where the structural system is some kind of grid of linear members rather than a surface. With today’s focus on environmentally friendly solutions, gridshells have gained increased relevance as ... -
Gro Field Assessment: A Lean Gas Condensate, Low Permeability Simulation Study
(Master thesis, 2011)New technologies increase the development of deep water fields and a significant portion of these undeveloped deep discoveries are gas condensates in low permeability reservoirs. This study is aimed at investigating the ... -
Grocery retail supply chain planning and control: Impact of consumer trends and enabling technologies
(Journal article; Peer reviewed, 2018)Grocery retail supply chains have in the past decades increased their efficiency which has led to cost-focused supply chains that are able to deliver high volumes of products at low prices. There is still continual pressure ... -
Ground source energy in crystalline bedrock - increased energy extraction by using hydraulic fracturing in boreholes
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:161, Doctoral thesis, 2004)The use of improved equipment and methodology can result in considerable reductions in the drilling costs for medium- to large sized ground source heat pump system in crystalline bedrock. The main point has been to use ... -
