Variable electricity generation from wind and solar influences the design of a cost-efficient and reliable energy system. This paper presents a method that uses stochastic programming to represent variable renewable electricity generation in long-term energy system models, and demonstrates this on a...
When studying work practices, it is important to obtain accurate and reliable information about how work is actually done. Action research is an interactive inquiry process that balances problemsolving actions implemented in a collaborative context with datadriven collaborative analysis or research...
A galvanic deposition method for the in-situ formation of Pt nanoparticles (NPs) on top and inner surfaces of high-aspect-ratio black TiO2-nanotube electrodes (bTNTs) for true utilization of their total surface area has been developed. Density functional theory calculations indicated that the...
Wind power can replace power from gas turbines and thus reduce the CO2 emissions related to oil production. However, a main challenge with wind power is the variability in power production due to weather variations. The water injection pumps are often major power consuming units. The water pumps...
Shallow geothermal reservoirs are excellent candidates for low-enthalpy energy storage, and can serve as heat batteries providing constant discharge of base heat, as well as rapid discharge of heat in periods of high demand. Recharging can be done by pumping down hot water, heated using excess heat...
Nyvinning kan stimuleres gjennom offentlige innkjøp. Akutten ved St. Olavs hospital viser vei og har lykkes gjennom en helt uvanlig idéjakt....
We present a multiscale approach to model a windfarm under real meteorological conditions. The multiscale model consists of a mesoscale atmospheric code coupled to a stochastic ocean wave model, a microscale model and a super-microscale model. The mesoscale model (with 2.5km×2.5km horizontal...
Først og fremst var et innovasjonsprosjekt med mål om å utvikle og ta i bruk en behovsdrevet og brukerstyrt digital læringsteknologi for å øke digital kompetanse i den norske skolen. Teknologien fra prosjektet skulle også forsterke den nasjonale satsningen "Sammen redder vi liv" og temaet...
This paper discusses components of service in healthcare. Four components of a service (service customer, service worker, service setting and service process) were introduced. Yet these components have not been explored in healthcare cases. We identified the key components through our case study...
