This paper identifies how Constant Voltage Load (CVL) characteristics cause Inductive Power Transfer (IPT) systems to exhibit a poorly damped oscillation mode. When operated with pulse skipping strategies such as Pulse Density Modulation (PDM), the skipped voltage pulses can excite this mode and...

Especially for wooden wall constructions, ventilated rain-screen walls have been used for many decades to prohibit moisture-induced damage. The air gap behind the façade cladding provides drainage, enhances ventilation, and thus facilitates drying of wetted façade components. The conditions in the...

Bakgrunn: Målet for denne forskningsstudien er å samle innspill til vilkår for ombruk av byggematerialer i Norge og de statlige føringene for dette. Vi har spurt om hvordan entrepriseformer, lovendringer, veiledning for offentlige anskaffelser, marked og økonomiske støtteordninger påvirker ombruk av...

Spørsmål til Barnehage-Norge 2021 presenterer resultatene fra den årlige spørreundersøkelsen fra Utdanningsdirektoratet til barnehagesektoren i Norge. Temaene i årets undersøkelse er: barn som er nyankomne fra Ukraina, digital praksis i barnehagen, barnehagemyndighetens organisering, lærlinger i...

Formålet med dette kunnskapsgrunnlaget er å belyse temaet bevisstgjøringsstrategier knyttet til informasjonssikkerhet og innsiderrisiko. På bakgrunn av en gjennomgang av eksisterende relevant forskningslitteratur innen sosialpsykologi, sikkerhetskultur og informasjonssikkerhet, fremstiller...

Chemical energy vectors will play a crucial role in the transition of the global energy system, due to their essential advantages in storing energy in form of gaseous, liquid, or solid fuels. Ammonia (NH₃) has been identified as a highly promising candidate, as it is carbon-free, can be stored at...

Materials used in the building envelope have to withstand a wide range of varying and harsh conditions over their life cycle. Particular relevance falls upon the materials used for tightening buildings, such as wind barriers and tapes, as air infiltration was found to be responsible for between...

The aim of the work was to study the effects of neighboring particles with uniform Stefan flow in particle–fluid flows. Particle-resolved numerical simulations were carried out for particles emitting a uniform Stefan flow into the bulk fluid. The bulk fluid was uniform and isothermal. The Stefan...

We address progressive local refinement of splines defined on axes parallel box-partitions and corresponding box-meshes in any space dimension. The refinement is specified by a sequence of mesh-rectangles (axes parallel hyperrectangles) in the mesh defining the spline spaces. In the 2-variate case a...
