Limitations in using runoff coefficients for green and gray roof design
(Peer reviewed; Journal article, 2020)Climate change combined with urbanization increases the performance demand on urban drainage systems. Green roofs are one of the most used green infrastructure measures to alleviate the pressure on the urban drainage system ... -
Limitations of the hydrotalcite formation in Portland composite cement pastes containing dolomite and metakaolin
(Journal article; Peer reviewed, 2018)This study focuses on the reaction of dolomite powder in combination with metakaolin in Portland composite cement pastes. We studied paste samples cured at 20 °C, 38 °C, and 60 °C for up to 1 year. In these systems, the ... -
Limiting current density as a selectivity factor in electrodialysis of multi-ionic mixtures
(Peer reviewed; Journal article, 2023)Electrodialysis is a promising technology to remove low concentrations of target ions from multi-ionic mixtures. While the synthesis of selective membranes is a prominent topic in research, few studies have been presented ... -
Limiting mechanisms for the torque density of wind turbine drivetrains
(Master thesis, 2019)As wind turbines continue to increase in size, so do the loads acting on the drivetrain. To handle the higher loads the mass of the drivetrain needs to increase. A better understanding of this mass increase can result in ... -
Limits to graphite supply in a transition to a post-fossil society
(Peer reviewed; Journal article, 2024)Transitioning to electric vehicles (EVs) powered by lithium-ion batteries (LIBs) aims at reducing emissions in the transportation sector, thereby decreasing fuel oil use and crude oil extraction. Yet, synthetic graphite, ... -
Limtre av furu utsatt for utmatting i langsgående skjær, og statisk langsgående skjær i kombinasjon med ortogonal strekk
(Master thesis, 2022)Sammendrag Utmatting av trekonstruksjoner er et relevant tema i byggenæringen, der det bygges store bruer og høye bygninger i tre. Det kreves derfor gode modeller til å dimensjonere trekonstruksjoner for utmattingslaster. ... -

Limtrekonstruksjonens utfordringer
(Bachelor thesis, 2022)Sammendrag Ifølge statistisk sentralbyrå så ble det bygget 93 kontor og forretningsbygg de siste 4 årene i Norge (Statistisk sentralbyrå, 2022). Basert på antakelser og erfaring mener vår veileder i Pro-Consult at det beste ... -
Line-focus solar concentration 10 times higher than the 2D thermodynamic limit
(Peer reviewed; Journal article, 2022)Line-focus solar concentrators have traditionally been limited by the 2D concentration limit due to the continuous translational symmetry in these systems. This limit is orders of magnitude lower than the 3D limit, severely ... -

(Master thesis, 2014)This report documents the progress, methods and engineering in building and testing theframework for CyberShip Enterprise 1. The main focus have been to modularize, standardize and improve the infrastructure and the operative ... -
Lineament mapping and its accuracy for forecasting weakness zones in tunnel construction. A case study of the Oslo region.
(Master thesis, 2023)Lineamentkartlegging er et mye brukt verktøy for å forutsi svakhetssoner i underjordiske installasjoner, men hvor nøyaktige er disse kartene? Denne masteroppgaven presenterer en statistisk analyse av nøyaktigheten til ... -
Linear analysis and multidisciplinary design optimization of the floater OO-Star
(Master thesis, 2021)In this report, in the continuity of B.de Renty's Master's thesis, a linear framework for the analysis and the optimization of floating wind turbines with automated diffraction/radiation computations, is proposed. A trial ... -
Linear and Nonlinear Analysis of a High-rise Building Excited by Earthquake: Lineær og ikke-lineær analyse av høyhus utsatt for jordskjelveksitasjon
(Master thesis, 2014)The purpose of this thesis is to evaluate the linear and nonlinear response of a high-rise building located in Norway. The Oslo Plaza building, located in Oslo, has been chosen for this purpose. A finite element model of ... -
Linear Flow Analysis Inspired by Mathematical Methods from Quantum Mechanics
(Peer reviewed; Journal article, 2022)Since its birth in the 1920s, quantum mechanics has motivated and advanced the analysis of linear operators. In this effort, it significantly contributed to the development of sophisticated mathematical tools in spectral ... -
Linear sloshing in a 2D rectangular tank with a flexible sidewall
(Journal article, 2017)A 2D rectangular sloshing tank with a flexible sidewall have been studied analytically and numerically, with a focus on the coupling between sloshing and the flexible wall. This analysis introduces new knowledge of the ... -
Linear wave response of a 2D closed flexible fish cage
(Journal article; Peer reviewed, 2019)Closed flexible fish cages (CFFC) are proposed as a new concept in marine aquaculture, replacing the conventional net cages in order to meet ecological challenges related to fish lice and escapes. A linear mathematical ... -
