utvärdering av en 'mixing-layer' hypotes
… by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations …
Hårdgörning av trä syftar till att göra materialet hårdare. Detta går att åstadkomma genom komprimering, det komprimerade materialet tenderar dock att återgå mot sin ursprungsform då materialet utsätts för fukt om ingen låsning sker. Låsningen kan ske mekaniskt i en …
… HMMlångfläck should be used to a greater extent on soils with thicker humus layer because it leads to higher exposition of mineral soil/heat. Another alternative could be to use wider wheels that make the scarified track wider. It would be possible to reduce the number of sown …
Konvektorers och nischdjupets inverkan på lufthastigheter i rummet
… is likely that this effective sill depth in large part depends on the boundary layer thickness at the window, in which case the constructors are given the alternative to determine the window sill depth by an easy estimation of the boundary layer thickness.
… means for a good thermal insulation consisting of skin, hair, and an outer air layer. The skin covers the horses body and it is composed of three main layers where the top layer of the epidermis consists of dead keratinized cells that are constantly being sheed. The dermis is …
… and the river Dalälven between Djurmo and Frostbrunnsdalen. The model has 6 layers and a cell resolution of 50 × 50 meters and 50 × 100 meters. The physical parameters of the model are comprised from different hydrological and geological investigations in the area. The Badelunda …
<em>Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät</em>
The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction ? geosynthetics. This …
… are presented separately. Cross laminated structures are composed of 3, 5 or 7 layers of timber and can be either unprotected or protected with a single gypsum board. The thickness of the load bearing and non-bearing layers has also been varied in different ways in order to …
Kontroll av zinkskikt på monterat räckesmaterial som görs ute i fält saknar en fastställd metod. Zinktjockleken har ett minimum tjocklekskrav enligt den svenska standarden ISO 1461:2009, som bestäms av dimensionen på ståldetaljens tjocklek. Trafikverket begär att med hjälp av …
… in the both cases, since the foam concrete must be cast in multiple layers. In addition, foam concrete requires more equipment, which results in a higher fixed cost. Foam concrete becomes, however, more profitable the larger volumes that are cast, because the fixed charges of …

… mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB. Six different materials; foam, glas fiber insulation, MDF, gypsum, concrete and glass are being investigated through Insul 7 simulations. A …
