Value of Investing in Information Security: A metastudy initiated by norSIS
(Master thesis, 2007)The ratio of companies and organizations in Norway with a number of employees between 5 and 9 and Internet access increased from 66% to 86% during a five year period from 2001 to 2006. This increased use of the Internet ... -
Value Tensions in Telecare: An Explorative Case Study
(Chapter, 2018)We describe the results from a Norwegian case study of the attitudes of community-dwelling lung patients and health response center personnel toward a telecare service for such a patient group. The telecare service was ... -
Value-Added Services, Virtual Enterprises and Data Spaces Inspired Enterprise Architecture for Smart Cities
(Chapter, 2019)As a part of their digital transformation, municipalities across Europe have taken initiatives to support Open Data platforms and provide services leveraging on data. This challenges the traditional business driven IT ... -
Valve Leakage Detection System Analysis and Development for Quituplex Pumps
(Master thesis, 2010)This thesis undertakes the study of digital signal processing in the purpose of an optimized and dynamic approach to the valve leakage detection problem. Several field tests were analyzed to evaluate the system properties ... -
Vanninntrengningsmonitor til undervanns-kontrollsystemer
(Bachelor thesis, 2024)Prosjektrapporten beskriver utvikling og vurdering av en VIM. I undervanns-kontrollmoduler er vanninntrenging et problem, som kan føre til systemfeil og i verste fall driftsstans. Dette er alvorlig, da dette kan føre til ... -

Vanntrevekst i mekanisk og elektrisk påkjente PEX-kabler
(Master thesis, 2011)Vanntredegradering er identifisert som en mekanisme som kan redusere levetiden til polymerisolerte kabler. Vanntrær vokser i elektrisk påkjente polymerisolerte kabler som utsettes for fuktige omgivelser. Kabler som skal ... -
VaR Estimation for Crude Oil Data via Different Approaches: Historical Simulations, EVT Model, and ACER Method
(Master thesis, 2018)This thesis implements different approaches to predict the one-day ahead Value at Risk (VaR) of crude oil return data. The Historical Simulation (HS) approach, a non-parametric model, randomly resamples past observations ... -
Variability Characteristics of European Wind and Solar Power Resources — A Review
(Journal article; Peer reviewed, 2016)This paper reviews the most recent and relevant research into the variability characteristics of wind and solar power resources in Europe. The background for this study is that wind and solar resources will probably ... -
Variable Flux Permanent Magnet Synchronous Machines: Building and Testing Simple Designs with High-Coercivity Magnets
(Master thesis, 2018)Variable flux permanent magnet synchronous machines (VF-PMSMs) use a novel operation concept based on changing the magnetization level of the permanent magnets in accordance with variations in speed and torque. This may ... -
Variable Selection and Redundancy in Multivariate Regression Models
(Journal article, 2022)Variable selection is a topic of interest in many scientific communities. Within chemometrics, where the number of variables for multi-channel instruments like NIR spectroscopy and metabolomics in many situations is larger ... -
Variable selection in Cox-models using the L1-regularization path algorithm
(Master thesis, 2010)The thesis give an overview of survival modelling and inference in Cox-models with high-dimensional covariates. -
Variable Speed Hydropower Conversion and Control
(Peer reviewed; Journal article, 2020)The objective of this paper is to develop and analyse a variable speed hydropower (VSHP) model that can aid the design of controllers that maximize the utilization of power plant for the provision of ancillary services, ... -

Variable step size commutator free Lie group integrators
(Journal article; Peer reviewed, 2019)We introduce variable step size commutator free Lie group integrators, where the error control is achieved using embedded Runge–Kutta pairs. These are schemes for the integration of initial value problems posed on homogeneous ... -
Variable-speed operation of hydropower plants: past, present, and future
(Journal article; Peer reviewed, 2018)In This article, the state of the art in the variable-speed operation of hydropower plants is reviewed, with a focus on pumped-storage hydropower. Relevant literature is reviewed to address the benefits of variable-speed ... -
Variance-Based Exploration for Learning Model Predictive Control
(Peer reviewed; Journal article, 2023)The combination of model predictive control (MPC) and learning methods has been gaining increasing attention as a tool to control systems that may be difficult to model. Using MPC as a function approximator in reinforcement ... -
Variantbegrensning av IKT-systemer i Forsvaret – krefter og motkrefter
(Master thesis, 2023)Forsvaret har fått kraftig kritikk på flere områder innenfor informasjons- og kommunikasjonsteknologi (IKT), blant annet for manglende måloppnåelse når det gjelder å redusere antall IKT-systemer og øke evnen til samhandling. ... -
