Application development using J2ME : evaluation of intrinsic platform limitations
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad The operating system Symbian OS and the programming language Java have existed in a symbiosis since the first version of Symbian OS arrived on the mobile scene. This thesis will explore important aspects of the mobile version of Java, namely the Java 2 Micro Edition, on Symbian OS based mobile phones. Part one of the thesis reviews the structure and evolution of Java 2 Micro Edition and the Symbian OS, and the symbiosis between them. This is done through a thorough theoretical investigation of the programming interfaces offered to the developer. Particularly certain problem areas such as hardware con…

Using Ericsson NorARC's frameworks as test bed for dynamic change of behavior based on CompositeStates
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad Frameworks are a widely used re-use technique in the object-oriented community today. A framework re-uses both code and design and makes it easier to develop new components. Ericsson NorARC (Norwegian Applied Research Center) has developed a set of frameworks; JavaFrame, ActorFrame and ServiceFrame to aid advance service development. JavaFrame is a modeling kit for Java with good support for state machines. ActorFrame is a framework emphasizing the actor and role notion. ServiceFrame emphasize the modeling of service functionality. UML is today’s de facto standard for visualizing, specifying, constru…
Sammenkobling av lyd og visuelle effekter ved hjelp av datateknologi
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad Sammenkobling av lyd og visuelle effekter kan man i dag se på diverse multimedieapplikasjoner. De applikasjonene som brukes i dag, bruker som regel metoder og algoritmer der man ser på frekvensene til et musikkstykke. Ser vi for eksempel på en mye brukt applikasjon som Windows Media Player, så brukes de forskjellige frekvensene i musikken vi velger å avspille for å gi visuelle effekter med mye farger og bevegelse. Dette prosjektet går et skritt videre ved å sette form og objekter til bestemte lyder og instrumenter i musikken og ikke særskilt til kun frekvenser. Ved å bruke metoder som er valgt av stu…
Preliminary photochemical studies of fluorene in various aqueous media
2014
- The current study investigates the direct photochemical degradation of aqueous fluorene with the aid of a 125W polychromatic medium, pressure Hg lamp. The purpose was to test the effectiveness of the lamp in irradiation using fluorene spiked solution as substrate. A 700 ml volume of fluorene solution of 0.002 mg/l was irradiated batch-wise at 1, 3, 6, 12, 18, 24 and 48 h. The amount of fluorene removal was studied for fluorene solutions prepared from , neutral (distilled water), acidic (by adjusting pH with hydrochloric acid, HCl), basic (by adjusting pH with sodium hydroxide, NaOH) and saline (addition of sodium chloride, NaCl) solutions and there was 95.95, 92.35, 96.65 and 97.15 % remo…
Harmonizing circumpolar monitoring of Arctic fox: benefits, opportunities, challenges and recommendations.
2017
Source at http://dx.doi.org/10.1080/17518369.2017.1319602 The biodiversity working group of the Arctic Council has developed pan-Arctic biodiversity monitoring plans to improve our ability to detect, understand and report on long-term change in Arctic biodiversity. The Arctic fox (Vulpes lagopus) was identified as a target of future monitoring because of its circumpolar distribution, ecological importance and reliance on Arctic ecosystems. We provide the first exhaustive survey of contemporary Arctic fox monitoring programmes, describing 34 projects located in eight countries. Monitored populations covered equally the four climate zones of the species’ distribution, and there were large dif…
Effects of simulated environmental changes on growth and growth form in a late snowbed population of pohlia wahlenbergii (Web. et Mohr) Andr
2003
In a factorial field experiment we increased the temperature (Open Top Chambers) and nutrients (nitrogen, phosphorus, and potassium [NPK]) to simulate predicted future climate changes and studied the growth response of the acrocarpous bryophyte Pohlia wahlenbergii (Bryaceae) in a wet snowbed environment. The species shows a positive growth-length response to added nutrients and increased temperature. The stronger response to nutrients indicates a strong limitation of nutrients in the snowbed environment. There was an immediate response to nutrient treatment, whereas the temperature response was delayed. The growth response shows a clear interaction between temperature and nutrients. The imm…
Spawning coloration and sperm quality in a large lake population of Arctic charr (Salmonidae: Salvelinus alpinus L.)
2009
The modern theories of sexual selection predict that male sexual ornaments may have evolved as reliable signals of male fertilization efficiency. However, among the studies of fishes with external fertilization, the results have yielded ambiguous evidence. In the present study, we present data on the phenotypic relationships between red spawning coloration and ejaculate quality (spermatocrit, sperm motility) from Arctic charr, Salvelinus alpinus. We studied two generations (F1 and F2) of males from a large lake population, reared in a standardized hatchery environment, to determine whether differential hatchery history, or duration of hatchery selection, affected the variation in ejaculate …

Matproduksjon, mattrygghet og miljø - innspill om kunnskapsbehov til gjennomføringen av det grønne skiftet - Uttalelse fra hovedkomiteen i Vitenskaps…
2022
Denne rapporten er utarbeidet av Vitenskapskomiteen for mat og miljø (VKM), en uavhengig, tverrfaglig komité som utarbeider kunnskapsgrunnlag for den norske mat- og miljøforvaltningen på områdene matproduksjon, mattrygghet og biologisk mangfold. De siste tiårene har FNs klimapanel, Det internasjonale naturpanelet, Det internasjonale ressurspanelet og flere andre paneler og organisasjoner levert rapporter som dokumenterer at befolkningsvekst og menneskelig aktivitet fører med seg store og økende utfordringer på miljø-, klima- og ressursområdet. Endringer innen disse områdene påvirker matproduksjon, matsikkerhet, mattrygghet, folkehelse og naturverdier i alle deler av verden (UNEP, 2021). Sam…
