Vekseldrift i tunnelbygging - Byggetid og usikkerhet
(Master thesis, 2022)Bakgrunnen for masteroppgaven er forankret i et uttalt behov fra bygge- og anleggsbransjen for en bransjeomforent tunnelbyggetidsmodell for mer korrekt beregning av tunnelbyggetid. Feil tunnelbyggetid er grobunn til ... -
Vektoranalyse med data målt med ETPOS, en tjeneste av Kartverket
(Bachelor thesis, 2020)I oppgaven undersøkes det om måling til kartverkets permanente basestasjoner ved hjelp av ETPOS metoden vil tilfredsstille nøyaktigheten for to fastmerker i Gjøvik-området til standarden Landsnett i grunnriss og høyde. Som ... -
Vellykket implementering av Last Planner System
(Master thesis, 2020)Lean Construction, og spesielt Last Planner System, har blitt foreslått som en løsning for å redusere sløsingen i produksjonsprosesser. Bygg- og anleggsbransjen har gjentatte ganger blitt kritisert for å ha for lav ... -
Velocity and pressure measurements in guide vane clearance gap of a low specific speed Francis turbine
(Journal article; Peer reviewed, 2016)In Francis turbine, a small clearance gap between the guide vanes and the cover plates is usually required to pivot guide vanes as a part of governing system. Deflection of cover plates and erosion of mating surfaces causes ... -
Velocity and Reflectivity variations of Overpressured Jurassic Sandstones in the Norwegian Sea
(Master thesis, 2016)The Garn Formation is one of the reservoir sands amongst the Jurassic Sandstones in the Norwegian-Sea. The pore-pressure and its influence on the rock properties within the Haltenbanken province in the Norwegian-Sea has ... -
Velocity Depth Trends Prediction on the Norwegian Continental Shelf (NCS) Wells Using the Bounding Average Method
(Master thesis, 2021)Earth consists of heterogeneous layers due to the complex sedimentation processes, in which lithifies both unconsolidated sand and siliciclastic clays into sandstone and shale. These two sedimentary rocks are the most ... -
Velocity dispersion in rocks: A laboratory technique for direct measurement of P-wave modulus at seismic frequencies
(Peer reviewed; Journal article, 2019)Fluid saturated rocks exhibit a dependence of acoustic velocities on frequency, which is called velocity dispersion. For some rocks, e.g. shales, velocity dispersion is rather strong and have to be taken into ... -
Velocity profiles in a 2D model of the left ventricular outflow tract, pathological case study using PIV and CFD modeling
(Chapter, 2017)In the current study, we present an experimental (in vitro) 2D flow model for studying blood flow in the human left ventricular outflow tract (LVOT) and the first part of the aorta using particle image velocimetry (PIV) ... -
Velocity ratio estimation using AVA attributes in VTI media
(Master thesis, 2017)Amplitude variation with angle (AVA) analysis is one of the fundamental tools for hydrocarbon detection and reservoir characterization. The background trend as a function of intercept against gradient for various 〈Vp〉/〈Vs〉 ... -
Velocity-attenuation model from check-shot drift trends in North Sea well data
(Peer reviewed; Journal article, 2020)Seismic attenuation distorts phase and narrows bandwidth in seismic surveys. It is also an exploration attribute, as, for example, gas or overpressure, may create attenuation anomalies. Compensating attenuation in imaging ... -
Vent Valve Thrust Force for Surface Effect Ships
(Journal article; Peer reviewed, 2019)The Surface Effect Ship (SES) holds promise as a viable and appealing alternative for transferring crew to offshore wind farms and oil platforms due to its superior seakeeping capability, high comfort and speed. A SES is ... -
Ventilasjon av fotballhaller
(Master thesis, 2018)I nye bygg blir det stadig strengere krav til ventilasjon, både med tanke på luftkvalitet og energibruk. Fotballhaller har til nå falt under radaren med sine uoppvarmede areal og mangel på ventilasjon. Bygningstypen har ... -
Ventilasjon av klasserom
(Master thesis, 2008)Sammendrag Oppgaven kommer som et resultat av et fordypningsprosjekt i 2007 - Ventilasjonseffektivitet i rom og lokaler med store variasjoner i lufttilførselen. Oppgaven gikk ut på å sette seg inn i simuleringsprogrammet ... -
Ventilated wooden roofs: Influence of local weather conditions-measurements
(Journal article; Peer reviewed, 2017)This study investigates the influence of temperature and air velocity conditions on ventilation and condensation in spring, summer and autumn periods inside a ventilated cavity in a full-scale wooden roof construction. The ... -
Ventilation design conditions associated with airborne bacteria levels within the wound area during surgical procedures: a systematic review
(Peer reviewed; Journal article, 2021)Background Without confirmation of the ventilation design conditions (typology and airflow rate), the common practice of identifying unidirectional airflow (UDAF) systems as equivalent to ultra-clean air ventilation ... -
Ventilation in low energy residences – a survey on code requirements, implementation barriers and operational challenges from seven European countries
(Peer reviewed; Journal article, 2020)This paper reports the results of an interview survey conducted among different stakeholders involved in design, installation and operation of residential ventilation in seven European countries. In total 44 interviews ... -
