Aerobic biological treatment of produced water from oil production

Knutsen, Trine (Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)

Produced water is the largest waste stream generated from the oil and gas industry. Water of varying quantities is always produced along with oil and has to be separated from the oil. The amount of produced water generated ...

Aerodynamic influence of an alpine skier’s arms

Giljarhus, Knut Erik Teigen; Reid, Robert Cortas; Liland, Fredrik Fang; Oggiano, Luca; Elfmark, Ola (Peer reviewed; Journal article, 2022)

Understanding how postural changes in alpine skiing affect the overall aerodynamic drag is highly important for enhancing performance. Although the arm configuration of the athlete can have a significant impact on the ...

Aerodynamic Investigation of Tucked Positions in Alpine Skiing

Elfmark, Ola; Giljarhus, Knut Erik Teigen; Liland, Fredrik Fang; Oggiano, Luca; Reid, Robert (Peer reviewed; Journal article, 2021)

The purpose of this investigation was to examine the aerodynamics of tucked positions in competitive alpine skiing. To further our understanding of how a skier’s position affects the air flow and the resulting aerodynamic ...

Aerodynamic loads on a wind turbine rotor in axial motion

Eliassen, Lene (PhD thesis UiS;245, Doctoral thesis, 2015-03-13)

This study investigates the unsteady aerodynamics of attached flow on a two-dimensional airfoil. The unsteady aerodynamics introduces aerodynamic damping of the offshore wind turbine structure and is thus important for ...

Aerodynamic modifications of tall buildings to mitigate wind response

Meltveit, Anders R.; Stangeland, Tor André (Bachelor thesis, 2021)

During the last century, there has been a huge development in the field of wind engineering. Wind tunnel testing in combination with CFD has made it possible for engineers to build tall irregular buildings. Today, Burj ...

Aerodynamic study of a suspension bridge deck by CFD simulations, wind tunnel tests and full-scale observations

Kusano, Ibuki; Cheynet, Etienne; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor (Peer reviewed; Journal article, 2021)

Assessing the aerodynamic characteristics of long-span bridges is fundamental for their design. Depending on the terrain complexity and local wind conditions, episodes of large angles of attack (AoA) of 15° may be observed. ...

Aeroelastic behavior of very long span suspension bridges

Dahl, Kristian (Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013-06-17)

The main purpose of this assignment has been to obtain and understanding of the challenges concerning a future very long span suspension bridge across Sognefjorden. I have through studies of existing literature and similar ...

Affordability influences nutritional quality of seafood consumption among income and race/ethnicity groups in the United States

Love, David C.; Thorne-Lyman, Andrew L.; Conrad, Zach; Gephart, Jessica A.; Asche, Frank; Godo-Solo, Dakoury; McDowell, Acree; Nussbaumer, Elizabeth M.; Bloem, Martin W. (Peer reviewed; Journal article, 2022)

Background The 2020 US Dietary Guidelines for Americans recommend that the US population consume more seafood. Most analyses of seafood consumption ignore heterogeneity in consumption patterns by species, nutritional ...

Age and Provenance study of Paleoarchean rocks from the Singhbhum Craton (India)

Dieset, Jacob (Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-08-13)

This study has performed in situ U-Pb and Lu-Hf isotope analysis on zircons and in situ U-Pb isotope analysis on apatites, by LA-ICP-MS and MC-ICPMS, from three Tonalite-Trondhjemite-Granodiorite (TTG) samples from ...

Ageing of ships, LPG tankers

Ask, Martin (Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2015-01-15)

During the last decades there have been several major ship accidents, and it is believed that old ships are more unsafe than newer ships. To get a better understanding of this phenomenon the thesis is investigating different ...
