Community Seismic Network

The article describes the design of the Community Seismic Network, which is a dense open seismic network based on low cost sensors. The inputs are from sensors hosted by volunteers from the community by direct connection to their personal computers, or through sensors built into mobile devices. The server is cloud-based for robustness and to dynamically handle the load of impulsive earthquake events. The main product of the network is a map of peak acceleration, delivered within seconds of the ground shaking. The lateral variations in the level of shaking will be valuable to first responders, and the waveform information from a dense network will allow detailed mapping of the rupture process. Sensors in buildings may be useful for monitoring the state-of-health of the structure after major shaking

Characterization and profiling of projector displays

NORSK: Dette er en analyse av hvordan digitale projektorer fungerer i ulike lysforhold og omgivelser. Både de bærbare og de fastmonterte projektorene ved Høgskolen i Gjøvik har blitt testet under fire ulike forhold: mørkt og lyst rom med og uten ICC-profil. Måleresultatene ble bearbeidet og analysert for å prøve å finne ut mer om hvor stor betydning lysforholdene i et rom har og hvor stort forbedringspotensiale det ligger i bruk av profil. Profilen ble laget ved hjelp av profileringsverktøyet Eye-One Beamer. Eye-One har en mye lavere pris enn for eksempel spektroradiometer som har vært vanlig å bruke når denne typen profiler skulle lages. Resultatene fra analysene viste at det var store visuelle forskjeller mellom de ulike projektorene. DLP-projektorer har generelt et mindre fargeomfang enn LCD-projektorene har. Fargeomfanget til eldre projektorer er betydelig mindre enn for nyere. Hvor mye lys som faller på lerretet fra andre lyskilder i rommet har mye å si for det visuelle inntrykket. Lyses lerretet opp virker det projiserte bildet blast og kontrastløst. Ved bruk av profil blir forskjellen mellom de ulike projektorene mindre og visuelt virker det som fargene blir mer riktige. Fargen blå vises med størst variasjon på de forskjellige projektorene og vil være vanskeligst å forutsi. Rød og grønn har grovt sett det samme fargeomfanget, men grønn er den mest stabile.ENGELSK: This is an analysis of how digital projector displays work under different conditions and lightning. Both the portable and the mounted projectors at Gjøvik University College have been tested under four different conditions: dark and light room with and without an ICC-profile. To find out more about the importance of the lightning conditions in a room and the level of improvement when using an ICC-profile, the results from the measuring was processed and analyzed. Eye-One Beamer was used to make the profile. Eye-One is a low cost product compared to spectroradiometers, which is commonly used when creating a profile for various equipments. The results from the analysis indicated great visual differences between the projectors. DLP projectors have generally smaller color gamut than LCD projectors. The color gamuts of older projectors are significantly smaller than that of newer ones. The amount of ambient light reaching the canvas is of great importance for the visual impression. If to much reflections and other ambient light reach the canvas, the projected image gets pale and has low contrast. When using a profile, the differences in colors between the projectors gets smaller and the colors appears more correct. The color blue has the greatest variations among the projector displays and makes it harder to predict. Red and green have generally the same color gamut, but green is the most stabile one

Omsetning av fjernleverbare tjenester i eller til Norge - Utenlandske virksomheters registreringsplikt ved omsetning av fjernleverbare tjenester til norske forbrukere

Executive Master of Management i Skatte- og avgiftsrett fra Handelshøyskolen BI, 2023Denne oppgaven undersøker hvordan utenlandske virksomheter skal ta stilling til hvordan de skal registrere seg for omsetning av fjernleverbare tjenester til norske forbrukere. Dette i lys av endringer i merverdiavgiftsloven fra 01.01.2023. Endringene fjernet det tidligere avgiftsfritaket for utenlandske virksomheter for omsetning av fjernleverbare tjenester til norske forbrukere og videreførte behovet for klarhet i killet mellom innenlandsk omsetning og omsetning til Norge. Oppgaven benytter juridisk metode og ser på norsk rettspraksis samt EU-regler for å identifisere relevante vurderinger og kriterier for klassifisering av omsetningen. Hovedfokus er på omsetningens art, om den foreligger innenfor eller utenfor merverdiavgiftsområdet, og om den kan anses som levering i eller til Norge. Det diskuteres om virksomheter uten fysisk tilstedeværelse og levering i Norge kan ha innenlandsk omsetning og hvilke konsekvenser de ulike registreringsordningene har. Oppgaven argumenterer for at det kreves en konkret vurdering av virksomhetens tilknytning til Norge, med hensyn til blant annet fysisk aktivitet, markedsføring og tilpasninger til Norge, samt avgiftsstatus i utlandet. Oppgaven avsluttes med refleksjoner over utfordringene Norge står overfor i håndteringen av merverdiavgift for digitale tjenester og foreslår mulige tiltak

Under-Reporting of Self-Reported Medical Conditions in Aviation: A Cross-Sectional Survey

BACKGROUND: The applicants’ self-declaration of medical history is crucial for safety. Some evidence indicates that under-reporting of medical conditions exists. However, the magnitude in a population of aviation personnel has not been reported earlier. METHODS: A total of 9941 applicants for medical certificate/attestation for aviation-related safety functions during the last 5 yr up to December 2019 were registered at the Civil Aviation Authority Norway. E-mail addresses were known for 9027 of these applicants, who were invited to participate in a web-based survey. RESULTS: Among the 1616 respondents, 726 (45%) were commercial pilots, 457 (28%) private pilots, 272 (17%) air traffic controllers, and the remaining were cabin crew or crew in aerodrome/helicopter flight information service (AFIS or HFIS, respectively). A total of 108 were initial applicants. The age group 50+ constituted the largest proportion of respondents (53%). Aeromedical certification in general was believed to improve flight safety “to a high” or “very high extent” by 64% of the respondents. A total of 188 individuals (12%) admitted having under-reported information related to one or more categories, including mental (3%) or physical health (4%), medications (2%), and drug use, including alcohol use (5%). Among these, 21 participants believed their own under-reporting “to some” or “to a high extent” affected flight safety. In total 50% of noninitial applicants reported that they knew colleagues who had under-reported information. Analyses revealed that being a commercial pilot showed a higher risk for under-reporting compared with other classes and the perception of aeromedical examiners in a supportive or authoritative role reduced the risk. CONCLUSIONS: Under-reporting of medical conditions could be significant in aviation. Further studies should be conducted to investigate the true extent of under-reporting and its impact on flight safety and what mitigating measures might be recommended

Gene content evolution in the arthropods

Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome. Dissection of the genomic record of sequence change enables broad questions regarding genome evolution to be addressed, even across hyper-diverse taxa within arthropods. Using 76 whole genome sequences representing 21 orders spanning more than 500 million years of arthropod evolution, we document changes in gene and protein domain content and provide temporal and phylogenetic context for interpreting these innovations. We identify many novel gene families that arose early in the evolution of arthropods and during the diversification of insects into modern orders. We reveal unexpected variation in patterns of DNA methylation across arthropods and examples of gene family and protein domain evolution coincident with the appearance of notable phenotypic and physiological adaptations such as flight, metamorphosis, sociality, and chemoperception. These analyses demonstrate how large-scale comparative genomics can provide broad new insights into the genotype to phenotype map and generate testable hypotheses about the evolution of animal diversity

Mesopelagic Species and Their Poential Contribution to Food and Feed Security - A Case Study from Norway

The projected increase in global population will demand a major increase in global food production. There is a need for more biomass from the ocean as future food and feed, preferentially from lower trophic levels. In this study, we estimated the mesopelagic biomass in three Norwegian fjords. We analyzed the nutrient composition in six of the most abundant mesopelagic species and evaluated their potential contribution to food and feed security. The six species make up a large part of the mesopelagic biomass in deep Norwegian fjords. Several of the analyzed mesopelagic species, especially the fish species Benthosema glaciale and Maurolicus muelleri, were nutrient dense, containing a high level of vitamin A1, calcium, selenium, iodine, eicopentaenoic acid (EPA), docosahexaenoic acid (DHA) and cetoleic acid. We were able to show that mesopelagic species, whose genus or family are found to be widespread and numerous around the globe, are nutrient dense sources of micronutrients and marine-based ingredients and may contribute significantly to global food and feed security.publishedVersio

Testing Via Internett Live

I dagens samfunn stilles det økende krav til effektivisering. Lærerne ved Høgskolen i Gjøvik bruker store ressurser for å lage og rette obligatoriske øvinger. Derfor ble det våren 2000 startet på et nettbasert system for testing av studenter, Testing Via Internet Live. Vi er den tredje prosjektgruppen som jobber med TVIL og det har nå blitt så robust og bra at det er ment tatt i bruk høsten 2002. Systemet har en lav brukerterskel og det er ment at studenter og lærere skal kunne ta det i bruk uten noen form for opplæring. Dette er en av styrkene til TVIL. Det er enkelt å opprette en test. Samtidig kan den mer erfarne lærer velge mellom de mange opsjonene og lage en spesialtilpasset test. De mange muligheter med systemet gjør testene like bra eller bedre enn skriftlige. Det lages i tillegg statistikk for hvert enkelt fag, test og spørsmål, noe som hjelper læreren til å bedre legge opp studieplanen. Studentene vil med dette systemet få en mye bedre mulighet til å sjekke sin egen progresjon med statustester som kan tilordnes et fag. De vil i tillegg få vite resultatet med en gang og kan sammenligne med nivået til de andre studentene vha statistikken som høer til hver test. Systemet er veldig enkelt å administrere, men superbruker har allikevel mange muligheter
