Preserving projection properties when regular two-level designs are blocked
(Peer reviewed; Journal article, 2022)Regular two-level designs are useful and popular screening designs, but if they need to be run in blocks, their projection properties can dramatically deteriorate. Interactions may be fully confounded with block defining ... -
Preserving Steganography Information Over Image Transformations
(Master thesis, 2022)Steganografi er kunsten å skjule informasjon i andre medium. Innen bildesteganografi blir skjulte meldinger gjemt i bilder som ser normale ut for det blotte øye, men som en mottaker kan hente ut den skjulte meldingen fra. ... -

(Research report, 2016)This is the final report of the project ProHealthPelagic (2012-2015) funded by the Norwegian Research Council, BIONÆR. The project aim was to investigate potential changes in well documented and tentative health promoting ... -
Preserving user privacy in location-aware systems: A protocol for privacy-preservation in location-aware systems
(Master thesis, 2011)This thesis main goal is to address issues which lies within location-awareness, concerning the privacy of the users.As smart-phones and other devices used for location-awareness are becom- ing more and more common among ... -
Presidentskifter og borgernes støtte til den afrikanske stat
(Master thesis, 2020)Har den etniske identiteten til statslederne i afrikanske land en innvirkning på borgernes nasjonale identifikasjon og deres vurdering av statenes legitimitet? Tidligere forskning har vist at den nasjonale identiteten til ... -
Presisjonslanding av telt i kriseområder
(Master thesis, 2017)I denne masteroppgaven er det bygget en prototype og utviklet et kontrollsystem for automatisk styring av en fallskjerm. Prototypen tar sikte på å styre en fallskjerm mot et forhåndsdefinert punkt. Kontrollsystemet er ... -
Press Form Hardening of Aluminium - The influence of hot forming, quench interruption and direct artificial aging on the mechanical properties of AA6082
(Master thesis, 2018)The automotive industry is in need of new lightweight solutions to meet stricter regulations regarding reduction in greenhouse gas emissions. Replacing steel components with age-hardenable high-strength aluminium alloys ... -
Press Form Hardening of Aluminium Alloys 7021 and 6082. A Feasibility Study.
(Master thesis, 2016)Aluminium alloys 6082.25 and 7021.50 were evaluated and compared as potential base materials for processing by press form hardening. Both extruded profiles and rolled sheets were assessed, however the rolled 7021 material ... -
Pressefotografiet som visualisering av Det hvite raseriet
(Master thesis, 2019)I denne masteravhandlingen studerer jeg pressefotografiets rolle i fremstillingen av høyreekstremisme gjennom VGs reportasjeserie Det hvite raseriet. Fremstillingen av individet står sentralt i studien, og jeg ser blant ... -

Pressure and inertia sensing drifters for glacial hydrology flow path measurements
(Peer reviewed; Journal article, 2020)Glacial hydrology plays an important role in the control of glacier dynamics, of sediment transport, and of fjord and proglacial ecosystems. Surface meltwater drains through glaciers via supraglacial, englacial and subglacial ... -
Pressure and strain measurement during hot extrusion of aluminium
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:50, Doctoral thesis, 2005)The aluminium extrusion process is based on simple principles, but allows profiles with the most complex cross-sectional shapes to be produced at a very high rate. One of the greatest challenges of aluminium extrusion is ... -
Pressure Control for Offshore Managed Pressure Drilling (MPD): Analysis, Design, and Experimental Validation
(Doctoral thesis at NTNU;2016:96, Doctoral thesis, 2016)Deepwater offshore drilling operations are among the most complex activities. For example in regions such as the Gulf of Mexico, wells are drilled in water depths of up to 3 kilometers, drilling depths can exceed 6 ... -
Pressure Control of Nonferroelastic Ferroelectric Domains in ErMnO<inf>3</inf>
(Journal article; Peer reviewed, 2023)Mechanical pressure controls the structural, electric, and magnetic order in solid-state systems, allowing tailoring of their physical properties. A well-established example is ferroelastic ferroelectrics, where the coupling ... -
Pressure controlled ventilation of the swimming pool
(Master thesis, 2019)Svømmehaller er komplekse bygninger med høyt energiforbruk og utfordrende innendørsforhold. Inneklimaet er varmt og fuktig, derfor må den mekaniske ventilasjonsteknikken beskytte bygningen mot fuktighet. Svømmeanlegg med ... -
Pressure drop in charge mixture in silicon production
(Master thesis, 2020)Lavere energiforbruk, en mer miljøvennlig produksjon og høyere silisium utbytte er viktige mål i silisium industrien. For å oppnå disse målene kreves det at prosessene i ovnen er stabile. Flere operasjonelle problemer har ... -
