Firefly optimization and mathematical modeling of a vehicle crash test based on single-mass
(Journal article; Peer reviewed, 2014)In this paper mathematical modeling of a vehicle crash test based on a single-mass is studied. The model under consideration consists of a single-mass coupled with a spring and/or a damper. The parameters for the spring ... -
Flow behavior in an agglomerated fluidized bed gasifier
(Peer reviewed; Journal article, 2019)The global energy demand has increased over the last decades and the need for utilization of energy produced from sustainable sources is stressed. Fluidized bed gasification of biomass is a thermochemical conversion process ... -

Fluidized bed calcination of cement raw meal: Laboratory experiments and CPFD simulations
(Journal article, 2020)The chemical and thermal processes associated with the decarbonation and fuel combustion in the cement kiln process produce a large amount of carbon dioxide (CO2) contributing with around 8 % of the global CO2 emissions. ... -
Fra fagbrev til ingeniør - et didaktisk perspektiv
(Journal article; Peer reviewed, 2011)Veien fra fagbrev eller annen yrkesutdanning til høgere utdanning har vært et tema i den norske skoledebatten i mange år, og er igjen blitt aktuell. Land som Finland, Tyskland og Japan har etablerte systemer for høgere ... -
Fusion of Body Sensors’ Data and Video Images in Assistive Technology
(Chapter, 2019)Modern innovations in the design of sensors and the convergence of computing, cognition and communications have led to many new possibilities in incorporating AI-techniques in Assistive Technology (AT) for elderly people. ... -
A fuzzy approach to rebust Social Sustainability Assessment(ISSA)
(Journal article, 2023)Social sustainability has been increasingly recognized as a fundamental component of sustainable development in recent years. It is still challenging to measure social sustainability in comparison to other dimensions of ... -
Gamma densitometry measurements of gas/liquid flow with low liquid fractions in horizontal and inclined pipes
(Journal article; Peer reviewed, 2018)The ability to accurately predict the volume fraction of different phases flowing in a pipe is of extreme importance to nuclear and oil industries, among others. This article will focus on the application of a single-beam ... -
Gasification of Biomass for Production of Syngas for Biofuel
(Journal article; Peer reviewed, 2015)Continuously increasing price of oil and gas, energy crisis and increased environmental consciousness towards the greenhouse gas emission have opened a new opportunity to the biomass, the oldest source of energy known to ... -
Granular sludge bed processes in anaerobic digestion of particle-rich substrates
(Peer reviewed; Journal article, 2019)Granular sludge bed (GSB) anaerobic digestion (AD) is a well-established method for efficient wastewater treatment, limited, however, by the wastewater particle content. This review is carried out to investigate how and ... -
Heat Pump Efficiencies simulated in Aspen HYSYS and Aspen Plus
(Journal article; Peer reviewed, 2015-11-25)Heat pump technology provides an efficient and sustainable solution for both heating and cooling. A traditional heat pump can be defined as a mechanical-compression cycle refrigeration system powered by electricity. ... -
Heavy Oil Production With Energy Effective Steam-assisted Gravity Drainage
(Journal article; Peer reviewed, 2016)In reservoirs with extra heavy oil and bitumen, thermal methods are used to reduce the viscosity, in order to extract the oil. Steam-assisted gravity drainage (SAGD) is a thermal method where continuous steam injection is ... -
High current arc erosion on copper electrodes in air
(Journal article; Peer reviewed, 2011)An arc fault inside metal enclosed switchgear will cause the pressure to rise and vaporization of electrode material may contribute to the pressure rise. An experimental study of high current arc erosion on copper electrodes ... -
High Pressure Moving Bed Biofilm Reactor for Syngas Fermentation
(Peer reviewed; Journal article, 2021)Two well-studied strategies to enhance syngas fermentation are elevated headspace pressure, increasing gas-liquid (GL) mass transfer, and moving bed biofilms (MBB) to overcome kinetic growth limitation. A combination of ... -
