High Performance Fine-Grained Biodegradable Mg-Zn-Ca Alloys Processed by Severe Plastic Deformation
(Journal article; Peer reviewed, 2019)The tensile strength, fatigue, and corrosion fatigue performance of the magnesium alloy ZX40 benefit strongly from hybrid deformation processing involving warm equal-channel angular pressing (ECAP) at the first step and ... -
High Performance Valve Spring Failure Mode Detection
(Master thesis, 2019)I denne oppgaven blir det undersøkt hvordan ventilmekanismen i en forbrenningsmotor styrer ventilene, og da spesielt med tanke på hvordan kamprofilen og vippearmenes oppsett samvirker for å generere løftkurven for ventilene. ... -
High pressure unlined tunnels: Exemplified with Nye Tyin Hydropower Project
(Master thesis, 2013)Topographic condition in Norway is favorable for the development of hydropower and more than 99% of annual production of energy in Norway is generated from hydropower. Unlined tunnels and underground powerhouses have been ... -
High strength and fatigue properties of Mg-Zn-Ca alloys after severe plastic deformation
(Journal article; Peer reviewed, 2019)Magnesium alloys are the lightest metallic structural materials with an outstanding specific strength. This makes them appealing for a wide range of applications in “green” transportation where weight saving is of major ... -
High-concentration freeform microtracking concentrators with single-axis external tracking
(Chapter, 2023)Microtracking concentrators enable the use of concentrator photovoltaics without the need for accurate two-axis external solar tracking. However, the wide tracking range required from stationary microtracking concentrators ... -
High-concentration wide-angle tracking integration with stacked lens arrays
(Chapter, 2019)Tracking-integration can reduce or eliminate the need for external solar tracking in CPV (concentrator photovoltaics). Previous research has shown how tracking-integrated systems can achieve high concentration ratios, wide ... -
High-performance polymer 3D printing – Open-source liquid cooled scalable printer design
(Peer reviewed; Journal article, 2022)To print high-performance polymers, a stable running printer that can reach high temperatures is needed. There is currently a lack of low-cost solutions that allow manipulation of process parameters and expansion of sensors ... -
High-performance stationary solar tracking through multi-objective optimization of beam-steering lens arrays
(Peer reviewed; Journal article, 2020)Beam-steering lens arrays enable solar tracking using millimeter-scale relative translation between a set of lens arrays. This may represent a promising alternative to the mechanical bulk of conventional solar trackers, ... -
High-Pressure Cooling in Turning of Inconel 625 with Ceramic Cutting Tools
(Journal article; Peer reviewed, 2018)Machining of heat resistant aerospace materials such as Inconel 625 or Inconel 718 is characterized by low cutting speeds, high tool wear rate, and high production costs. The machinability of heat resistant super alloys ... -
Hjelpemiddel for påtrekking av kompresjonsstrømper
(Master thesis, 2013)Kompresjonsstrømper er svært stramme strømper som benyttes av mange, særlig eldre, for å bedre blodomløpet i beina. Svært mange har problemer med å påføre kompresjonsstrømper og trenger hjelp til dette. Hjelpepleiere som ... -
