The aim was to produce data to find a suited test method and sand parameters for determination of the void ratio parameter for crushed sand to be used in the "particle-matrix-model – PMM. PMM considers workability from the volumetric ratio between the viscous matrix phase and the solid...
There is generally a lack of knowledge on how marine organic carbon accumulation is linked to vertical export and primary productivity patterns in the Arctic Ocean. Despite the fact that annual primary production in the Arctic has increased as a consequence of shrinking sea ice, its effect on flux...
The prediction of the early age behavior of cementitious materials is a difficult task, because many of the material properties are very sensitive to curing conditions as it is the case for High Performance Concrete (HPC), which usually has a very low water to cement ratio (0.2 < w/c ≤ 0.3). Early...
This work presents a Volt/VAr Management System, based on a Model Predictive Control strategy, which can be applied for managing dynamic network resilience. Dynamic network resilience, in this context, is associated with resilient microgrid operation (stable voltage profiles within admissible range...
With the recent developments of Internet of Things (IoT) and cloud-based technologies, massive amounts of data are generated by heterogeneous sources and stored through dedicated cloud solutions. Often organizations generate much more data than they are able to interpret, and current Cloud Computing...
Older wooden doors can be one of the weaker points with regards to fire resistance in apartment buildings. This guideline proposes how glass, protective boards, sealing lists, hardware and door frames can be mounted to the door to be expected to achieve a fire resistance of approximately 30 minutes...
Kompakte tak er tak som består av ett eller flere materiallag som ligger i en tett sandwich-konstruksjon uten luftsjikt. I omvendte kompakte tak er det vanntette sjiktet (takmembranen) plassert under isolasjonssjiktet. Dette fører til et ekstra varmetap i omvendte kompakte tak sammenliknet med...
Maritime transport is investigating several options to reduce its greenhouse gases and air pollutant emissions. An experimental ship, Energy Observer, is using excess renewable energy to generate onboard hydrogen by electrolysis of purified seawater. As a promising option for storing energy, it can...
Utviklingen mot utslippsfri byggeprosess er godt i gang i Norge, men veien videre avhenger både av teknologiutviklingen og hva som skjer på det internasjonale markedet....
