L'action pour le climat, une action contre l'emploi? Évaluation des conséquences du scénario à 2 °C sur l'emploi
(Journal article; Peer reviewed, 2018)L'Accord de Paris fixe pour objectif de limiter le réchauffement climatique à 2 °C. Il faudra pour cela accroître la part des énergies renouvelables et améliorer l'efficacité énergétique. Une telle transition énergétique ... -
¿La acción climática destruye empleos? Efectos del objetivo de los 2 °C del Acuerdo de París en el empleo
(Journal article; Peer reviewed, 2018)El Acuerdo de París establece el objetivo de mantener el calentamiento global por debajo de los 2 °C a partir de los niveles preindustriales. Ello puede lograrse aumentando la proporción de energías renovables y la eficiencia ... -
Labor Embodied in Trade: The Role of Labor and Energy Productivity and Implications for Greenhouse Gas Emissions
(Journal article; Peer reviewed, 2014)Global production chains carry environmental and socioeconomic impacts embodied in each traded good and service. Even though labor and energy productivities tend to be higher for domestic production in high‐income countries ... -
Laboratory studies of paper calendering using a pendulum device
(Dr. ingeniøravhandling, 0809-103X; 2001:108, Doctoral thesis, 2001)The present thesis refers experimental and theoretical studies of the calendering process making use of the pendulum device as a means to simulate the roller calendering. The main task has been to clarify characteristic ... -
Ladestasjon for elbil i Svolvær
(Bachelor thesis, 2021)Vågan kommune ligger i Lofoten, en region som i stor grad er avhengig av turisme. Kommunen ønsker å sette opp en ny ladestasjon i byen Svolvær, for å gjøre regionen mer attraktiv for turister som ankommer med elbil. Oppgaven ... -
Lading og lagring av varme i energibrønner for bygningsoppvarming
(Master thesis, 2014)Et grunnvarmebasert system kan benyttes til oppvarming av bygg. Hvis borehullene er plassert med en avstand på 5-7 m, må termisk energi tilbakeføres til borehullene for å opprettholde effektiviteten til systemet. Med en ... -
Lagrangian Three-phase Slug Tracking Methods
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:305, Doctoral thesis, 2013)The increasing amount of water produced from maturing oil and gas wells, and the growing need for development of smaller remote fields, puts higher requirements on accurate predictions of threephase flows in transport ... -
Land Use and Land Use Change Impacts on Terrestrial Habitats from Hydropower Development in the LCA framework
(Master thesis, 2014)Anthropogenically driven biodiversity loss is one of the major challenges of modern society. The main cause of biodiversity loss is habitat fragmentation and destruction. Hydropower causes transformation and occupation of ... -
Land use for bioenergy: Synergies and trade-offs between sustainable development goals
(Peer reviewed; Journal article, 2022)Bioenergy aims to reduce greenhouse gas (GHG) emissions and contribute to meeting global climate change mitigation targets. Nevertheless, several sustainability concerns are associated with bioenergy, especially related ... -
The land–energy–water nexus of global bioenergy potentials from abandoned cropland
(Peer reviewed; Journal article, 2021)Bioenergy is a key option in climate change mitigation scenarios. Growing perennial grasses on recently abandoned cropland is a near-term strategy for gradual bioenergy deployment with reduced risks for food security and ... -
Langmuir-type vortices in wall-bounded flows driven by a criss-cross wavy wall topography
(Peer reviewed; Journal article, 2020)We investigate a mechanism to manipulate wall-bounded flows whereby wave-like undulations of the wall topography drives the creation of bespoke longitudinal vortices. A resonant interaction between the ambient vorticity ... -
Large eddy simulation of CH4-air and C2H4-air combustion in a model annular gas turbine combustor
(Journal article; Peer reviewed, 2018)Combustion instabilities are one of the major challenges in developing and operating propulsion and power generating gas-turbine engines. More specifically, techniques for managing the increasingly stringent emissions ... -
Large Eddy Simulation of Turbulent Combustion with Chemical Kinetics
(Doktoravhandlinger ved NTNU, 1503-8181, Doctoral thesis, 2011)The present doctoral thesis studies and develops methodologies for turbulent combustion with the Large Eddy Simulation (LES). Three main objectives for present doctoral thesis were. First, development of LES methodology ... -
Large potentials for energy saving and greenhouse gas emission reductions from large-scale deployment of zero emission building technologies in a national building stock
(Peer reviewed; Journal article, 2021)High energy and material demand in the building sector causes large greenhouse gas (GHG) emissions. This sector needs large-scale technological improvements in the transition to a future low-emission society. Extensive ... -
Large scale heat storage for district heating

Large Time Step Explicit Schemes for Partial Differential Evolution Equations
(Master thesis, 2016)We consider the large time step (LTS) method for hyperbolic conservation laws, originally proposed by LeVeque in a series of papers over thirty years ago. In particular we have designed a local multi-point LTS scheme, ... -
