Low Temperature Applications for CO2 Capture in Hydrogen Production
(Chapter, 2020)The recent development of the protonic membrane reformer (PMR) technology allows an energy efficient hydrogen production from natural gas. To liquefy and separate CO2 from the retentate gas of the PMR, various low temperature ... -
Low temperature drying and thermo-physical Properties of Brown seaweeds (Saccharina latissima)
(Chapter, 2017)The drying kinetics of brown seaweed Sacharina Latissima with and without blanching were investigated in temperature range between 10.0 and 38.0 °C. The drying process is more rapid for raw seaweeds. The effective moisture ... -
Low Temperature Plate Freezing of Fish on boats using R744 as Refrigerant and Cold Thermal Energy Storage
(Master thesis, 2018)The introduction of low temperature R744 freezing systems enables lower evaporating temperatures and faster freezing times, however, also a lower system efficiency (COP). This thesis will investigate how low temperature ... -
Low velocity impact on crash components with steel skins and polymer foam cores
(Journal article; Peer reviewed, 2019)Energy absorbing systems are extensively used in the automotive industry to ensure crashworthiness. Such crash components could typically consist of a sandwich structure with thin ductile plates as skins and a cellular ... -

Low- and Zero-Emission Hybrid-Electric Power Systems for Passenger Ferries
(Master thesis, 2021)Den maritime industrien er blitt oppfordret til å redusere klimagassutslippene betydelig, med et mål om en reduksjon på 50% innen 2050 sammenliknet med 2008-nivåene. Dette har oppmuntret til utvikling av nye lav- og ... -
A Low-cost and Accurate Microwave Sensor System for Permittivity Characterization
(Peer reviewed; Journal article, 2022)A novel low-cost microwave sensor system is proposed for accurate sensing of the real relative permittivity of materials under test (MUT). The proposed solution eliminates the need for using advanced measurement devices ... -
Low-Cost AUV for High Resolution Photogrammetry Data Acquisition
(Master thesis, 2019)I undervannsteknikk finnes det få løsninger for å gjøre undersøkelser innen fotogrammetri effektivt fra en godt egnet undervannsfarkost, spesielt til lav kostnad og med høy navigasjonsnøyaktighet. Fjernstyrte undervannsfarkoster ... -
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 ... -
