Low-cost Navigation and Collision Avoidance System
(Master thesis, 2020)Ettersom teknologien rundt autonome bakke-kjøretøy (AGV’er) stadig er i utvikling, trenger man også mer datakraft for å realisere disse systemene. Samtidig er lav-kost ettkorts datamaskiner (SBC’er) med høy ytelse blitt ... -
Low-Cost Observer and Path-Following Adaptive Autopilot for Ships
(Master thesis, 2017)In this thesis a signal-based observer and a path-following autopilot design will be derived and implemented on the model vessel C/S Enterprise I. Using scaling methods the goal is to transfer the controllers into a full ... -
A low-cost predictive display for teleoperation: Investigating effects on human performance and workload
(Peer reviewed; Journal article, 2020)Teleoperation in an environment with latency is difficult and highly stressful for human operators, resulting in high cognitive workload and decreased human performance. This work investigates if a simple predictive display ... -
Low-cost tooling concept for customized tube bending by the use of additive manufacturing
(Peer reviewed; Journal article, 2023)Bending is commonly used in the manufacturing of finished and semi-finished, profilebased products. However, costly profile and bend geometry dependent tooling hampers its applicability for low volume production or ... -
Low-cost tooling concepts for customized tube bending processes using hybrid design and additive manufacturing
(Master thesis, 2023)Denne oppgavens fokus vil være på den fleksible bøyeprosessen som tar plass i en rørbøyingsmaskin. Denne forminsprosessen tar inn en aluminiumsrør og bøyer det til den ønskede formen, med de rette dimensjonene. Det endelige ... -
A low-cost vibration isolation chamber – Making high precision experiments accessible
(Peer reviewed; Journal article, 2022)Mechanical vibrations greatly influence sensitive instruments and experiments, yet they are unavoidable. Commercial solutions that mitigate the transfer of mechanical vibrations into experiments and instruments are often ... -
Low-cycle fatigue behavior of 10CrNi3MoV high strength steel and its undermatched welds
(Journal article; Peer reviewed, 2018)The use of high strength steel allows the design of lighter, more slender and simpler structures due to high strength and favorable ductility. Nevertheless, the increase of yield strength does not guarantee the corresponding ... -
Low-cycle fatigue behaviour of AISI 18Ni300 maraging steel produced by selective laser melting
(Journal article; Peer reviewed, 2018)Selective laser melting has received a great deal of attention in recent years. Nevertheless, research has been mainly focused on the technical issues and their relationship with the final microstructure and monotonic ... -
Low-Emissivity Materials for Building Applications: A State-of-the-Art Review and Future Research Perspectives
(Journal article; Peer reviewed, 2015)Low-emissivity (low-e) materials can be used in order to reduce energy usage in both opaque and transparent areas of a building. The main focus for low-e materials is to reduce the heat transfer through thermal radiation. ... -
Low-frequency acoustic signal created by rising air-gun bubble
(Journal article; Peer reviewed, 2017)In the seismic industry, there is increasing interest in generating and recording low frequencies, which leads to better data quality and can be important for full-waveform inversion. The air gun is a seismic source with ... -
Low-frequency dynamic wake meandering: comparison of FAST.Farm and DIWA software tools
(Journal article; Peer reviewed, 2021)Most of the global dynamic response models used today for the design of wind turbines are based on the aero-hydro-servo-elastic analysis of one single turbine. However, research on bottom- fixed offshore wind turbines has ... -
Low-Frequency Hydrodynamic Modeling of a 12 MW Semi-Submersible Wind Turbine
(Master thesis, 2021)INO WINDMOOR-plattformen er en semi-submersible konstruksjon for å støtte en 12 MW vindturbin. Dens naturlige frekvenser i bølge og tonehøyde er under frekvensene til typisk bølgeenergi, og store resonansbevegelser kan ... -
Low-frequency oscillations in flow past an inclined prolate spheroid
(Journal article; Peer reviewed, 2019)We analyse the forces on a 45∘ inclined 6:1 prolate spheroid at Reynolds number ReD = 8000. In contrast to flow at lower Reynolds numbers previously investigated, we now find a strong oscillatory behaviour in the global ... -
Low-head pumped hydro storage: A review of applicable technologies for design, grid integration, control and modelling
(Peer reviewed; Journal article, 2022)To counteract a potential reduction in grid stability caused by a rapidly growing share of intermittent renewable energy sources within our electrical grids, large scale deployment of energy storage will become indispensable. ... -
