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 ... -
Hjulopphengs rig for virtuell og fysisk dynamisk testing
(Master thesis, 2016)Som følge av at faget TMM4155 - Produktutvikling og materialer skulle bli oppdatert, hadde ansvarlig for kurset, Terje Rølvåg ønske om å lage nytt undervisningsopplegg. Dette skulle inneholde mer praktiske oppgaver, og et ... -
HNBR elastomer composite with zero thermal contraction over a range of temperatures
(Journal article; Peer reviewed, 2019)Elastomers such as hydrogenated nitrile butadiene rubber (HNBR) are known to have inferior dimensional stability upon temperature changes compared to metallic materials. This can result in thermal contraction mismatches ... -
Hockeykjelke - Setebunn og knestøtte: Utvikling av ny kjelke til det norske kjelkehockeylandslaget
(Master thesis, 2013)Kjelkehockey er basert på de samme prinsippene som ishockey, men er rettet mot utøvere med funksjonsnedsettelser i nedre del av kroppen. Utøverne sitter i en tilpasset kjelke med skøytestål på undersiden av bakre del av ... -
Hospital project front-end planning: Current practice and discovered challenges
(Peer reviewed; Journal article, 2020)Development of healthcare services is a societal responsibility often appearing as major public projects. These types of projects often have a long lifetime expectancy and represent large investments and changes to established ... -
How a project alliance influences project performance compared to traditional project practice – Findings from a case study in the Norwegian oil and gas industry
(Peer reviewed; Journal article, 2022)Practitioners and researchers have turned their attention toward collaborative arrangements and new Collaborative Project Delivery Models (CPDMs). In this paper we present findings from a study focusing on the impact of a ... -
How Combinations of Industry 4.0 Technology Support Circular Economy
(Master thesis, 2023)Verden står fremfor samtlige globale utfordringer relatert til aspekter slik som ressurs mangel, klima forandringer, og økende generering av avfall. Sirkulær økonomi tilbyr en mulig løsning for å adressere mange av de ... -
How much hydrogen is in green steel?
(Journal article; Peer reviewed, 2023)Hydrogen-based reduction of iron ores is the key technology for future sustainable ironmaking, to mitigate the CO2 burden from the steel industry, accounting for ~7–8% of all global emissions. However, using hydrogen as a ... -
How Norwegian Manufacturing Companies Deal with Innovation in Product Development Projects Using Qualitative Data Gathering Methods
(Master thesis, 2019)Some research on innovation, complexity and newness can be found in the literature, although most of this research focuses on industries related to large construction projects or development of new products. But how do ... -
How square ice helps lubrication
(Journal article, 2017)In the context of friction we use atomistic molecular-dynamics simulations to investigate water confined between graphene sheets over a wide range of pressures. We find that thermal equilibration of the confined water is ... -
