Variational Mode Decomposition-Based Threat Classification for Fiber Optic Distributed Acoustic Sensing
(Peer reviewed; Journal article, 2020)In this study, a novel method is proposed to detect and classify the threats for fiber optic distributed acoustic sensing (DAS) systems. In the study, phase-sensitive optical time-domain reflectometry (phase-OTDR) is ... -
Variational multiscale reinforcement learning for discovering reduced order closure models of nonlinear spatiotemporal transport systems
(Peer reviewed; Journal article, 2022)A central challenge in the computational modeling and simulation of a multitude of science applications is to achieve robust and accurate closures for their coarse-grained representations due to underlying highly nonlinear ... -
Variations of Joint Integrated Data Association With Radar and Target-Provided Measurements
(Peer reviewed; Journal article, 2023)Target tracking algorithms are usually based on exteroceptive measurements obtained from sensors placed in the center of some surveillance area. However, information transmitted from surrounding targets will often also be ... -
Varmegjenvinning i fryseanlegg med bruk av ejektorsystem
(Master thesis, 2011)I denne studien er en forsøksrigg konstruert for å undersøke en ejektorkrets med CO2 som kuldemedie. Disse forsøksdataene blir videre benyttet for å beregne energieffektiviseringspotensialet ved å implementere et ejektorsystem ... -
Varmeovergang og strømningsfordeling i varmetekniske komponenter
(Master thesis, 2007)Sammendrag del 1: Miljømessige problemer som følge av utslipp av klimagasser og knapphet på fossile brensler har tvunget bilindustrien til å lete etter alternative måter å operere kjøretøy på. Hydrogen blir betraktet som ... -
Varmereguleringssystem for testing av komponenter i termisk vakuum
(Bachelor thesis, 2022)Orbit NTNU er en teknisk organisasjon som konstruerer kubesatellitter. Før en slik satellitt skytes ut i verdensrommet er det viktig at den blir testet grundig, for å sjekke at den tåler vakuum-tilstanden i rommet og ... -

Varmestyring for effektreduksjon
(Bachelor thesis, 2022)Våren 2021 vedtok Olje- og Energi departementet å endre nettleigemodellen basert på NVE sitt forslag. NVE foreslår at nettleiga i større grad må legge til rette for betre utnytting av straumnettet, samt ei rimelegare ... -
The VAROS Synthetic Underwater Data Set: Towards realistic multi-sensor underwater data with ground truth
(Peer reviewed; Journal article, 2021)Underwater visual perception requires being able to deal with bad and rapidly varying illumination and with reduced visibility due to water turbidity. The verification of such algorithms is crucial for safe and efficient ... -
Varying disease-mediated selection at different life-history stages of Atlantic salmon in fresh water
(Journal article; Peer reviewed, 2011)Laboratory studies on associations between disease resistance and susceptibility and major histocompatibility (MH) genes in Atlantic salmon Salmo salar have shown the importance of immunogenetics in understanding the ... -
The vascular occlusion test using multispectral imaging: a validation study
(Peer reviewed; Journal article, 2020)Multispectral imaging (MSI) is a new, non-invasive method to continuously measure oxygenation and microcirculatory perfusion, but has limitedly been validated in healthy volunteers. The present study aimed to validate the ... -
Vascular Pattern Recognition: And its Application in Privacy-Preserving Biometric Online-Banking Systems
(Doktorgradsavhandlinger ved Høgskolen i Gjøvik;2/2012, Doctoral thesis, 2012-10-04)Authentication is a key building block in security systems and many applications to prevent access to information, services, assets or locations for non-authorized persons or processes. Common methods based on knowledge ... -

Vector Field Path Following of Static Sinusoidal Paths for Underwater Snake Robots
(Chapter, 2023)In this paper, a guiding vector field (GVF) approach is applied to solve the path-following problem of a static unbounded sinusoidal path for an underwater snake robot (USR) in the presence of constant irrotational currents. ... -
Vector fitting for estimation of turbine governing system parameters
(Chapter, 2017)With the introduction of more and more renewables into the power system both the inertia and the primary frequency reserves are expected to decrease. It is therefore a growing concern that the frequency quality will ... -
