Unsettled settlement? Translocal social anchoring and patterns of (im)mobility among Polish families in rural Norway
(Peer reviewed; Journal article, 2021)Whilst the transnational family life of post-accession intra-European migrants has been extensively explored, past studies have rarely addressed its local dimension. The relatively recent international migration patterns ... -

Unstable Gas Lift at the Heidrun Field
(Master thesis, 2017)Gas lift is used in oil wells to maintain the production by injecting gas into the tubing. The dynamics of the system often causes pressure variations and a fluctuating flow rate. Others have proposed design concepts for ... -
The Unstable Object: Glifo, Blow, and Sacco at MoMA, 1972
(Peer reviewed; Journal article, 2020)This article discusses three radical objects—the Glifo shelf from 1966, the Blow chair from 1967 and the Sacco chair from 1968—that were all exhibited at Museum of Modern Art’s ground-breaking architecture and design ... -
The Unstable Rock Slopes Træstane and Hest in Sørfjorden - Structural Mapping and Hazard assessment for Different Failure Scenarios
(Master thesis, 2018)The geological survey of Norway carries out a systematic mapping of potential unstable rock slopes in Norway. In context of this, a hazard analysis and preliminary consequence assessment has been undertaken at the two ... -
Unstable splittings in Hodge filtered Brown-Peterson cohomology
(Journal article, 2018)We construct Hodge filtered function spaces associated to infinite loop spaces. For Brown–Peterson cohomology, we show that the corresponding Hodge filtered spaces satisfy an analog of Wilson’s unstable splitting. As a ... -
Unstable two phase flow in long vertical pipes
(Master thesis, 2018)Flow instabilities can cause operational problems when transporting multiphase mixtures of oil and gas in offshore risers and pipelines. Several types of flow instabilities have been studied and are well documented. This ... -
Unsteady flow in wicket gate and runner with focus on static and dynamic load on runner
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:155, Doctoral thesis, 2007)This thesis presents a study on unsteady flow at the inlet of the runner in a Francis turbine. The main goal has been to find a connection between the design of the wicket gate and the dynamic load on the runner due to ... -
Unsteady hydrodynamic forces of solid objects vertically entering the water surface
(Journal article; Peer reviewed, 2019)We investigate the unsteady hydrodynamic force of solid objects vertically entering water with an air cavity behind the falling body. Physical models are proposed to represent the force components corresponding to the body ... -
Unsteady RANS Simulation of Flow around Rectangular Cylinders with different Aspect Ratios at High Reynolds Number
(Master thesis, 2014)Computational Fluid Dynamics (CFD) has been used to evaluate essential hydrodynamic quantities and flow structures around rectangular cylinders with different chord length to depth ratios (aspect ratios) at high Reynolds ... -
Unstructured bin picking of multiple shiny objects using machine learning and 3D computer vision
(Master thesis, 2021)Denne oppgaven presenterer utviklingen av et automatisert system for ustrukturert ``bin picking'' av blanke deler. Hensikten med systemet er at Siemens Energy AS skal bruke det for automatisk kitting av materialstativvogner ... -
Unstructured PEBI-grids Adapting to Geological Features in Subsurface Reservoirs
(Master thesis, 2016)Extensive research has been done on the generation of unstructured grids in reservoir simulation, with the aim of better representing the geology. We introduce UPR (Unstructured PEBI-grids for Reservoirs), a free, open ... -
Unstructured Voronoi grids conforming to lower-dimensional objects
(Journal article; Peer reviewed, 2018)We present a novel mixed-dimensional method for generating unstructured polyhedral grids that conform to prescribed geometric objects in arbitrary dimensions. Two types of conformity are introduced: (i) control-point ... -
Unsupervised Anomaly Detection
(Master thesis, 2023)Denne forskningen tar sikte på å undersøke om uovervåket unormal deteksjon kan brukes til å oppdage unormaliteter i samtaler brukt i et svært partisk datasett. Et nettchatbasert datasett fra selskapet Børns Vilkår ble ... -
Unsupervised Anomaly Detection based on Machine Learning
(Master thesis, 2019)Satsningen på digitalisering og implementering av konsepter som inngår i Industri 4.0 har aldri vært større, hvor tilstandsovervåkning, implementering av sensorteknologi og prediktive strategier for vedlikehold står i ... -
Unsupervised Anomaly Detection for IoT-Based Multivariate Time Series: Existing Solutions, Performance Analysis and Future Directions
(Peer reviewed; Journal article, 2023)The recent wave of digitalization is characterized by the widespread deployment of sensors in many different environments, e.g., multi-sensor systems represent a critical enabling technology towards full autonomy in ... -
Unsupervised Anomaly Detection on Streaming Data in the Petroleum Industry Using Deep Neural Networks
(Master thesis, 2019)Moderne produksjonssystemer innen olje og gass er intensivt overvåket av et stort antall sensorer og tilstandsovervåkende utstyr. Dette generer enorme mengder data som kontinuerlig strømmes til produksjonsdataplattformer, ... -
Unsupervised Band Selection with SPPF: A Spectral-Spatial Fuzzy Clustering Approach
(Master thesis, 2023)Anskaffelsen av et hyperspektralt bilde (HSI) innebærer å fange flere spektrale bånd innenfor et bestemt bølgelengdeområde. Behandling av HSIer er imidlertid krevende på grunn av den enorme mengden data. Båndseleksjons ... -
