Versatile Simulation Method for Complex Single Mixed Refrigerant Natural Gas Liquefaction Processes
(Peer reviewed; Journal article, 2018)Natural gas liquefaction is an energy intensive process with very small driving forces particularly in the low temperature region. Small temperature differences in the heat exchangers and high operating and capital costs ... -
Vertical earthquake response of a Submerged Floating Tunnel including Seaquake loading
(Master thesis, 2017)This MS thesis investigates vertical seismic response in time domain on the proposed concept for a SFT with vertical tension leg design located at Bjørnafjorden. A 3D beam model is employed to conduct seismic analysis on ... -
Vertical Green Structures to Establish Sustainable Built Environment: A Systematic Market Review
(Peer reviewed; Journal article, 2022)Vertical Green Structures (VGS) emerged as a building skin Nature-based Solution (NbS) aside from green roofs. The motivation underlying this VGS exploitation is fast urbanisation and the need to limit both land consumption ... -
Vertical Lift Modules for small items order picking: an economic evaluation
(Journal article; Peer reviewed, 2019)Small items order picking is a very labour-intensive activity which is often performed in a dedicated area equipped with carton racks and with the operators walking within the aisles to pick the required products. Recently, ... -
Vertical Solution for ETO Companies Using Microsoft Dynamics AX
(Master thesis, 2014)ERP systems are useful for MTS and ATO manufacturing strategies. When evaluating the ERP systems in an ETO environment there is not much research available on the matter, but the general understanding is that ERP system ... -

Vertical Stratification in a Ventilated Space: Comparison of Theoretical Predictions to Experimental Results from a Water Scale Model
(Master thesis, 2007)This study investigates the behaviour of a vertically distributed source of buoyancy on the vertical stratification in a ventilated space, an important factor for determining indoor comfort when using displacement ventilation. ... -
Vertical vs. Lateral Dynamic Behaviour of Soft Catenaries subject to Regular Loading using Field Measurements
(Journal article, 2020)During the last couple of decades, there has been a steady increase in the development of higher-speed railways. Higher speeds increase the demands on existing railway infrastructure designed for older and different ... -
Vertical Wave Loads and Response of a Floating Fish Farm with Circular Collar
(Master thesis, 2011)In this master thesis the vertical wave loads and vertical responses of the floating collar of a circular fish farm have been investigated. The response has been investigated for a collar without the presence of mooring ... -
Vertical Wind Profiles in Non-Neutral Conditions: Comparison of Models and Measurements From Frøya
(Journal article; Peer reviewed, 2018)This paper presents an analysis of stratification dependent mean velocity profiles measured in a Norwegian coastal wind climate, and its comparison with models available in the literature. For this purpose we use 3 years ... -
Vessel hydrodynamic model tuning by Discrete Bayesian updating using simulated onboard sensor data
(Peer reviewed; Journal article, 2021)Vessel and wave hydrodynamics are fundamental for vessel motion prediction. Improving hydrodynamic model accuracy without compromising computational efficiency has always been of high interest for safe and cost-effective ... -
Vessel Operations in Exposed Aquaculture: Achieving safe and efficient operation of vessel fleets in fish farm systems experiencing challenging metocean conditions
(Doctoral theses at NTNU;2023:42, Doctoral thesis, 2023)Fartøysoperasjoner i eksponert havbruk Eksponert havbruk vil kreve at servicebåter brukt i havbruksnæringa er tilpasset mer krevende sjøkondisjoner enn i skjermede lokaliteter, slik at evne til å utføre marine operasjoner ... -
VETA i anleggsbransjen
(Bachelor thesis, 2016)Hensikten med denne rapporten er at det er i Veidekke Industri AS sin interesse å ta i bruk programmer som skal visuelt presentere valsedokumentasjon. Byggherren stiller strengere krav til dokumentasjon på store kontrakter, ... -
Viability study of Acoustic Emission for condition monitoring of coiled tubing
(Master thesis, 2017)Acoustic emission refers to the dispersal of elastic waves generated by crack initiation and other damaging mechanisms within a material. Recording and analyzing these waves form the foundation of the monitoring technique ... -
Vibration Measurement and Wave Reflection Analysis in an Electrified Railway Catenary Based on Analytical Methods
(Peer reviewed; Journal article, 2021)The wave propagation property of the catenary directly affects the pantograph–catenary interaction performance. Specifically, wave reflection and transmission occurring at waveguide discontinuities, particularly at dropper ... -
