(Master thesis, 2023)Fjellankere, også kalt strekkforankringer eller bare forankringer, består av lastbærende komponenter stag eller kabler som brukes til å stabilisere storskala infrastrukturer i bergmasser og til å forsterke undergrunnen, ... -
Laboratorieundersøkelse av mekanisk nedbryting og fin stoffproduksjon hos pukk brukt til vei og jernbane
(Master thesis, 2011)For å bygge best mulig veger og jernbane er det stilt kvalitetskrav til pukken som blir brukt i granulære bærelag. Den må være av god kvalitet for å tåle belastningen og vibrasjonene den blir utsattfor. Levetiden til disse ... -
Laboratory and Numerical Study of Scaling Parameters Used in Modelling of CO2 Storage in Rocks
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:254, Doctoral thesis, 2014)Storage of CO2 in deep saline formations is currently the most promising option for mitigating the impact of climatic changes. The main concern related to CO2 storage in geological formation is safety. It is necessary that ... -
Laboratory Characterisation of a Commercial RGB CMOS Camera for Measuring Night Sky Brightness
(Peer reviewed; Journal article, 2023)The use of RGB cameras in photometric applications has grown over the last few decades in many fields such as industrial applications, light engineering and the analysis of the quality of the night sky. In this last field, ... -
Laboratory Evaluation of Static and Dynamic Sag in Oil-Based Drilling Fluids
(Journal article; Peer reviewed, 2020)In this paper, we present the results of barite sag measurements before and after hot-rolled oil-based drilling fluids (OBDFs) using different approaches for characterization. We characterized the barite sag of a liquid ... -
Laboratory experiments on shared-energy collisions between freshwater ice blocks and a floating steel structure
(Journal article; Peer reviewed, 2017)Ship collisions with floating ice in which the ship sustains damage are in the shared-energy regime – both the ice and the ship dissipate energy through inelastic deformations. The physics of these events are rarely studied. ... -
Laboratory investigation of frost susceptibility of crushed rock aggregates and field assessment of frost heave and frost depth
(Doctoral theses at NTNU;2020:335, Doctoral thesis, 2020)In Nordic countries that experience seasonal frost, understanding how it affects the service life of linear transport infrastructures such as roads and railways is essential. Frost action both regroup frost heave and thaw ... -
Laboratory Investigation of Impact of Injection–Abstraction Rate and Groundwater Flow Velocity on Groundwater Heat Pump Performance
(Peer reviewed; Journal article, 2023)Using low-temperature (shallow) groundwater as a heat source or heat sink is a common practice to supply space heating or cooling, especially in the United States, Canada, China, and several European countries. The groundwater ... -
Laboratory Investigation of Low Salinity Waterflooding as a Tertiary Recovery Process: Effect of Crude Oil Composition
(Master thesis, 2011)Low salinity water flooding has been established in relevant literature as a promising method for enhanced oil recovery. The presence of polar components within the oil has been established as a necessity for any effect ... -
Laboratory investigation of performance of a screen type debris-flow countermeasure
(Journal article; Peer reviewed, 2018)Debris-flows are forms of landslides in mountainous regions that can potentially cause significant damage. Structural countermeasures to mitigate an entire debris-flow may become unrealistically massive and expensive. If ... -
Laboratory Investigation of the Pore Pressure Built-Up in Moving Debris
(Master thesis, 2015)Debris flow poses significant threat to property and human life mainly as a result of its high sediment concentrations and mobility. For the purpose of predicting debris flow mobility and mitigating potential damage, ... -
Laboratory Investigation on Development of Bitumen Exposed to Chemicals
(Doctoral theses at NTNU;2022:186, Doctoral thesis, 2022)As one of the most significant components of asphalt concrete, bitumen is crucial to the durability and lifespan of asphalt pavement. The asphalt pavement is exposed to different external conditions, such as traffic loading, ... -
