Reduksjon av klimagassutslipp fra massivtrekonstruksjoner

Nyhammer, Synnøve; Auran, Rolf Sæbø (Bachelor thesis, 2022)

Bruk av bærekonstruksjon i tre er å foretrekke før stål og betong med tanke på å redusere klimafotavtrykket til bygninger. Bygninger der krysslaminerte treelementer (massivtre) utgjør komponenter som vegger, tak og ...

Reduksjon av konfliktpunkter i plan- og toplanskryss

Hetty, Gustav (Master thesis, 2022)

I Norge gjennomføres en betydelig andel av alle reiser med personbil. Det er store samfunnsøkonomiske kostnader knyttet til både reisetid, køkjøring og ulykker i biltrafikken. Et effektivt og sikkert transportsystem som ...

Reduksjon av sløsing i produksjon på byggeplass

Mjelve, Marie (Master thesis, 2016)

Høye byggekostnader og lav produktivitet er to av byggenæringens største utfordringer. Det er et ønske i næringen om at produktiviteten skal forbedres og kostnadene skal reduseres. Reduksjon av sløsingen i produksjon antas ...

REDWIN – REDucing cost in offshore WINd by integrated structural and geotechnical design

Skau, Kristoffer Skjolden; Page, Ana M.; Kaynia, Amir M.; Løvholt, Finn; Norén-Cosgriff, Karin; Sturm, Hendrik; Andersen, H.S.; Nygaard, Tor Anders; Jostad, Hans Petter; Eiksund, Gudmund Reidar; Havmøller, O.; Strøm, P.; Eichler, D. (Journal article; Peer reviewed, 2018)

The cost of offshore wind energy production has to be reduced continuously to improve its competitiveness compared to other energy sources. To contribute to this goal, a 4- year research project REDWIN – REDucing cost of ...

REEF3D Wave Generation Interface for Commercial CFD Codes

Pakozdi, Csaba; Bihs, Hans; Kamath, Arun; Hermundstad, Elin Marita (Chapter, 2019)

In recent years CFD developments have shown a trend to combine RANS CFD simulation with other methods such as wave theories or velocity potential based numerical wave tanks, in order to reduce to computation costs. This ...

REEF3D Wave Generation Interface for Commercial Computational Fluid Dynamics Codes

Pakozdi, Csaba; Bihs, Hans; Kamath, Arun (Peer reviewed; Journal article, 2021)

In recent years, computational fluid dynamics (CFD) developments have shown a trend to combine Reynolds-averaged Navier–Stokes (RANS) CFD simulation with other methods such as wave theories or velocity potential-based ...

Bihs, Hans; Wang, Weizhi; Pakozdi, Csaba; Kamath, Arun (Peer reviewed; Journal article, 2020)

In situations where the calculation of ocean wave propagation and impact on structures are required, fast numerical solvers are desired in order to find relevant wave events. Computational fluid dynamics (CFD)-based numerical ...

A Reformed Empirical Equation for the Discharge Coefficient of Free-Flowing Type-A Piano Key Weirs

Kadia, Subhojit; Pummer, Elena Marianne; Kumar, Binit; Rüther, Nils; Ahmad, Zulfequar (Peer reviewed; Journal article, 2023)

The existing equations for the discharge coefficient of Piano key weirs (PKWs) use a limited range of experimental data, which means that they are inappropriate for wide parametric ranges that might lead to significant ...

Regaining of strength over time in remoulded clays

Alnajim, Shaima Ali Hassan (Master thesis, 2011)

Regain rate of strength in remoulded clays with time has been investigated and evaluated in this study. The clays loose much of the original strength after disturbance, especially in quick clay where the strength after ...
