This paper investigates the use of the class-E inverter for power factor correction (PFC) applications. Analytical and state-space models are derived showing the class-E inverter’s capability of achieving inherent PFC operation with a constant duty cycle. The inherent PFC operation limits the controller responsibility to the regulation of the output voltage, which is key for resonant converters with ...

This paper presents the benefits of PVA fibers in improving the mechanical properties of class F fly-ash-based geopolymer concrete. The activator used in the geopolymer was 8M sodium hydroxide (NaOH) and sodium silicate (Na₂SiO₃), with a mass ratio of Na₂SiO₃ to NaOH varied from 1.5 to 2.5. Cylindrical specimens with a diameter of 100 mm and a height of ...

Plastic pollution is ubiquitous across marine environments, yet detection of anthropogenic debris in the global oceans is in its infancy. Here, we exploit high-resolution multispectral satellite imagery over the North Pacific Ocean and information from GPS-tracked floating plastic conglomerates to explore the potential for detecting marine plastic debris via spaceborne remote sensing platforms. ...

Adherence to the complex set of recommended self-care practices among people with Sickle-Cell Disease (SCD) positively impacts health outcomes. However, few patients possess the required skills (i.e. disease-specific knowledge, adequate levels of self-efficacy). Consequently, adherence rates remain low and only 1% of patients are empowered enough to master the self-care practices. Health coaching ...

While expectations are well-known drivers of electronic health record (EHR) adoption, the drivers of expectations are more elusive. On the basis of interviews with general practitioners (GPs), we investigate how the early implementation process drives their expectations of an EHR that is being implemented in Norway. The GPs’ expectations of the prospective EHR are driven by (a) satisfying experiences ...

We investigate German–Russian bilingual children's sensitivity to formal and semantic cues when assigning gender to nouns in German. Across languages, young children have been shown to primarily rely on phonological cues, whereas sensitivity to semantic and syntactic cues increases with age. With its semi-transparent gender assignment system, where both formal and semantic cues are psycho linguistically ...

The Paleoproterozoic Greenstone Belts of Fennoscandia are metamorphosed and deformed volcanic and sedimentary basins with a high metallic ore potential. One of those, the Alta-Kvænangen Tectonic Window (AKTW), is exposed as a window below the Caledonides of Northern Norway. The Kåfjord area located within the AKTW hosts numerous known Cu occurrences. The Cu mineralisation in Kåfjord occurs mostly ...

Hovedoppgaven var en del av et større forskningsprosjekt i regi av professorene Ingunn Skre og Rannveig Grøm Sæle. Tidligere studier har forsøkt å kartlegge faktorer som henger sammen med å ha fordommer mot temaet psykisk helse hos ungdom. Kjønn og alder har vist seg å være av betydning, da å være yngre og å være gutt henger sammen mer fordommer mot temaet. Det finnes imidlertid ikke nok studier til ...

This thesis investigates cross-linguistic influence (CLI) in L3 acquisition among North Sámi-Norwegian bilinguals in comparison to Norwegian monolingual controls. The linguistic phenomena of investigation include subject-verb agreement and verb placement. The main overarching inquiry of this study is to determine if North Sámi-Norwegian bilinguals acquire English (as an L3) in the same fashion as ...

This master thesis presents an original investigation on Error Analysis on the L2 / L3 teaching of Spanish, specifically about the use of conditional structures involving subjunctive by a group of secondary school native Norwegian students. The research starts from a corpus consisting on a number of directed grammar activities done by the student group during one semester, and proposes a classification ...
