Comparison of Accelerated Climate Ageing Methods of Polymer Building Materials by Attenuated Total Reflectance Fourier Transform Infrared Radiation Spectroscopy
(Journal article; Peer reviewed, 2011)The degradation of the polymer building materials polypropylene (PP) and high density polyethylene (HDPE) intended for application as water barriers/repellants around building foundation walls have been studied. The PP and ... -
A comparison of cost and time overrun causes in different road size projects
(Master thesis, 2018)Within the road construction industry there have been many attempts to identify the major cost and time overrun causes. However, it seems that a comparation between these factors for projects of different size has not ... -
Comparison of different approaches to load calculation for the OWEC Quattropod jacket support structure
(Journal article; Peer reviewed, 2014)Accurate load simulations are necessary in order to design cost-efficient support structures for offshore wind turbines. Due to software limitations and confidentiality issues, support structures are often designed with ... -
Comparison of different mixing methods in field and laboratory stabilized clay
(Master thesis, 2023)Grunnforsterkning ved dypstabilisering er en vanlig måte å forbedre jordegenskaper samtidig som man unngår unødvendig grave- og fyllearbeid. En maskin med boretårn stabiliserer jorda ved å injisere et bindemiddel gjennom ... -
A comparison of different wave modelling techniques in an open-source hydrodynamic framework
(Peer reviewed; Journal article, 2020)Modern design for marine and coastal activities places increasing focus on numerical simulations. Several numerical wave models have been developed in the past few decades with various techniques and assumptions. Those ... -
Comparison of Environmental impact of Hydropower and Wind Power
(Master thesis, 2022)One of the best ways to reduce the effects of climate change is to increase electricity production from renewable sources, which offers an excellent prospect for low carbon emissions and greenhouse gas reduction, However, ... -
Comparison of Geoacoustic Models for Unfrozen Water Content Estimation
(Peer reviewed; Journal article, 2020)This paper reviews eight geoacoustic models applied to frozen soils: crystal growth models (grain cementing, grain coating, matrix supporting, and pore filling), the weighted equation (WE) model, Zimmerman and King's model ... -
Comparison of impulse based substructuring and fully coupled analysis for offshore wind turbines
(Master thesis, 2014)With an ever increasing demand for clean renewable energy, wind energy is a rapidly expanding market. Due to noise and visual pollution as well as limited space on land, offshore wind turbines are getting more popular. One ... -
Comparison of in-situ measurements from the Norströmsgrund lighthouse to Copernicus reanalysis products
(Chapter, 2020)Here, we aim to extend the full-scale data measurements of ice conditions and the resulting structure behaviour at the Norströmsgrund lighthouse to other locations in the Baltic Sea via comparison to the met-ocean conditions ... -
Comparison of Kinematic wave and Hydraulic model simulated water level along river sections
(Master thesis, 2022)Norge har opplevd flere storflommer i de siste årene på grunn av betydelige variasjoner i sesongavhengig vannføring og nedbør. Kommunene har prioritert bruk av moderne hydrologiske modelleringsverktøy for å håndtere slike ... -
A Comparison of the classical and recent formulae of handling the effects of close and distant topographic masses in gravimetric geoid computations
(Journal article; Peer reviewed, 2003)Different procedures for considering the effects of topographic masses in Stokes- Helmert scheme of geoid determination are reviewed. Classical integral formulae use a planar approximation of the geoid and a limited area ... -
Comparison of the condition of steel fiber-reinforced shotcrete with water-glass and alkali-free activators after more than 20 years of service in a subsea road tunnel
(Peer reviewed; Journal article, 2022)The in-service condition of steel fiber-reinforced shotcrete installed more than 20 years ago as single-shell rock support lining in the Nordkapp subsea road tunnel was investigated. The novelty of this study is the ... -
Comparison of the Energy Performance between Flat-plate and Heat Pipe Evacuated Tube Collectors for Solar Water Heating Systems under Mediterranean Climate Conditions
(Journal article; Peer reviewed, 2019)In this paper, the energy performance of a flat-plate collector and a heat pipe evacuated tube collector exploited for domestic hot water production in the Mediterranean climate is compared. For this purpose, yearly data ... -
Comparison of the Energy Saving Potential of Adaptive and Controllable Smart Windows - A State-of-the-Art Review and Simulation Studies of Thermochromic, Photochromic and Electrochromic Technologies
(Master thesis, 2018)Today s building sector in the EU stands for about 40 % of the total energy consumption and about 75 % of all buildings are energy inefficient. By making both the new and the existing buildings smarter and more energy ... -
Comparison of the Energy Saving Potential of Adaptive and Controllable Smart Windows: A State-of-the-Art Review and Simulation Studies of Thermochromic, Photochromic and Electrochromic Technologies
(Journal article; Peer reviewed, 2019)Windows play a huge role in today’s buildings, allowing for outside view and providing occupants with daylight. However, windows are also often considered to be one of the weakest building components with respect to high ... -
