Experimental set-up of a thermal vacuum chamber for thermal model in-house correlation and characterization of the HYPSO hyperspectral imager
(Peer reviewed; Journal article, 2023)Space environment with changing temperatures and vacuum can affect the performance of optics instruments onboard satellites. Thermal models and tests are typically done to understand the optics performance within large ... -
Experimental set-up of the Double Slip Joint - Investigating the settling behaviour
(Master thesis, 2015)The Double Slip Joint (DSJ) is a new design to connect the transition piece to the foundation pile of an oshore wind turbine. It potentially oers high dynamic strength and reliability at a lower cost thereby assisting the ... -
Experimental setup and testing of an in-field system for real- time occupant feedback
(Journal article; Peer reviewed, 2019)Thermal comfort and air quality in buildings have been found to be the 2nd and 5th largest sources of complaints among occupants in modern office buildings. In building operation, the determination of control set-points ... -
Experimental setup for high-temperature in situ studies of crystallization of thin films with atmosphere control
(Peer reviewed; Journal article, 2020)Understanding the crystallization process for chemical solution deposition (CSD) processed thin films is key in designing the fabrication strategy for obtaining high-quality devices. Here, an in situ sample environment is ... -
Experimental Setup Simulating Hoarfrost Formation on Roadways
(Peer reviewed; Journal article, 2020)Hoarfrost on roadways and bridges can cause slippery and dangerous conditions for motorists. To reduce the costs and environmental impact of countermeasures, road authorities wish to optimize their winter maintenance ... -
Experimental sleep restriction increases latency jitter in pain elicited cortical responses
(Peer reviewed; Journal article, 2021)Objective Previous studies have shown increased pain scores to painful stimulation after experimental sleep restriction, but reduced or unchanged magnitude of the event related potentials (ERPs) when averaged in the ... -
Experimental Strength Analysis and Material Modelling of 3D Printed Parts
(Master thesis, 2019)Ingeniørens omfattende kunnskaper om styrkeanalyser er i all hovedsak basert på tradis- jonell analysemetodikk fra langt tilbake i tid. Nå som verden beveger seg fremover, popper det stadig opp nye teknologier, produkter, ... -
