Copepods dominate the mesozooplankton spring-summer community in a South Norwegian fjord
2021
Master's thesis in Coastal ecology (BIO501) In this study the seasonality of the mesozooplankton community in spring and summer of 2019 at Midtfjordsskjær (MFS), South Norway, was investigated. Zooplankton samples were collected using a fine mesh sized plankton net (60 μm) and zooplankton were identified by microscopy based on 5 ml subsamples. Total zooplankton abundance ranged from 754 –1620 ind. m-3and peak abundance was found in May. Holoplankton dominated spring and summer communities at MFS constituting between 85,6 –98,8% of total zooplankton.
Kvalitativ og kvantitativ inventering av fiskesamfunnet i Ytre Oslofjord : En beskrivelse av diversitet og generelle trekk ved fiskesamfunnet i Færde…

Master's thesis in Coastal ecology (BIO501) A three-year study was performed annually from 2017 to 2019 in Færder- and Ytre Hvaler national parks located in outer Oslofjord. Data collection was conducted in shallow- and deep water habitats using catch-based methodologies in 2017 - 2019 (eel fyke net and trap) and visual methodology (stereo-video)in 2019. In the period of study, a total of 9733 individual fish were recorded among 37 species from 19 families. Shallow water fish assemblage (1 - 10 m) sampled by fyke net was dominated by a selection of wrasses (goldsinny wrasse and corkwing wrasse) and small, stationary species of non-commercial importance. Sampled by trap at deeper habitats (1…
Allee effects and the Allee-effect zone in northwest Atlantic cod
2022
According to the theory of compensatory dynamics, depleted populations should recover when the threat responsible for their decline is removed because per capita population growth is assumed to be highest when populations are at their smallest viable sizes. Yet, many seriously depleted fish populations have failed to recover despite threat mitigation. Atlantic cod (Gadus morhua) stocks off Newfoundland, despite 30 years of dramatically reduced fishing mortality and numerous fishery closures, have not recovered, suggesting that drivers other than fishing can regulate the growth of collapsed fish populations, inhibiting or preventing their recovery. Here, using Bayesian inference, we show str…

Positive and negative factors in agent oriented software development : a case study
2006
Masteroppgave i informasjonssystemer 2006 - Høgskolen i Agder, Kristiansand This thesis attempts to pinpoint the main differences in agent oriented software engineering as opposed to more legacy approaches. The agent paradigm, still in its infancy, is believed to offer exciting new prospects to the process of modern complex information systems development, but although many tools, frameworks and applications are readily available, there is as of yet no specific research on how these technologies affects and differ the development process. The research approach in finding these factors was two-folded. By conducting a comprehensive literature study, a set of implications was derived to repres…
Customer involvement in new service development : how does customer involvement enhance new service success?
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad This master thesis investigates how customer involvement enhances new service development and investigates what role the service characteristics play for this development. An exploratory and quantitative empirical research was conducted among small and medium sized firms in selected business categories. Before the empirical work could be conducted a thorough literature study on innovation research, service research and customer involvement was completed. Literature from new product development was also included. The literature study showed that services have been treated as something different from t…
Adoption of M-Commerce
2002
Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad The development of ICT in recent years, and speed of this development is extremely rapid. ICT also spreads widely and influences deeply not only economic activities of business, households and governments but also various areas of people’s daily life. The adoption rate of mobile Internet was estimated by analogy to adoption pattern. This study examines patterns of mobile commerce adoption and usage in early adopters. One hundred and ninety mobile users were surveyed about their pattern of usage, demographic and socioeconomic characteristics, perception about the technology, and their motivation to us…
Mobile operators' business models in the mobile data service market
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad In the mobile data service market there are several different actors. The main actors are the operator, the content provider, the aggregator and the sub-contractor. The operator is often in control of the market and has the content providers and aggregators connected to them. The sub-contractors are connected to the operator via the aggregators. All operators have a business model towards their content providers, and are in this area often referred to as content provider access (CPA). The model is the connection between the operator and a content provider or aggregator. The CPA agreement contains a l…
Flerkanals multimedia over IP
2001
Masteroppgave i informasjons- og kommunikasjonsteknologi 2001 - Høgskolen i Agder, Grimstad Denne diplomoppgaven tar for seg multimedia over IP ved bruk av videokonferanse. To møterom blir forsøkt innredet med høykapasitets videokonferanseutstyr med flere parallelle videokanaler. Ideen er å benytte disse til å øke den sosiale nærheten og unnvike kikkehullseffekten, slik at man kan utnytte dette til å skape bedre rammer for kreativt samarbeid på tvers av lange distanser. Vi diskuterer oppstilling av utstyr med bruk av et godt videokonferanseverktøy, måter å øke muligheten for øyekontakt og det å kunne henvende seg til den enkelte i et møte. Vi rapporter enkelte brukererfaringer og lærdommer …
Optimalisering av modulasjon og koding for å muliggjøre høyere datarater i videreutviklingen av eksisterende Inmarsat satellittkommunikasjonssystemer
2002
Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad Inmarsat plasserer en ny generasjon satellitter i geostasjonærbane i løpet av 2003/04. De nye satellittene vil være 100 ganger kraftigere enn dagens og vil kunne øke kommunikasjons-kapasiteten betraktelig. Denne rapporten ser på muligheten til å øke dataraten i videreutviklingen av Nera SatCom AS sitt eksisterende utstyr når de nye satellittene tas i bruk. Det er vurdert kombinasjoner av modulasjonsmetoder og koderater for å kunne øke dataraten. Kombinasjonene er vurdert med hensyn på kritiske parametre i en satellitt link. Resultatene viser at en økning i dataraten er fullt mulig med lavere ordens m…
