Ingen utøver –ingen offer : Hvordan forebygge seksuelle overgrep mot barn? En kvalitativ studie av erfaringer, tanker og refleksjoner fra mennesker s…
2021
Master's thesis in Sociology and social work (ME522) Det er behov for mer kunnskap om den alvorlige problematikken som omhandler seksuelle overgrep mot barn for å komme frem til bedre forebyggende tiltak. Formålet med avhandlingen er å løfte frem et viktig tema for både samfunnet, utsatte, deres pårørende og for mennesker som arbeider med tematikken. Avhandlingen legger fokus på utøverperspektivet, forekomst og samfunnsøkonomiske konsekvenser knyttet til barn som blir utsatt for seksuelle overgrep. Det er ønskelig at avhandlingen skal belyse viktigheten av økt kunnskap rundt utøver og hvordan denne kunnskapen kan bidra til å forebygge seksuelle overgrep mot barn. Det kastes lys over konsekv…

Master's thesis in Sociology and social work (ME522)
En vurdering til besvær : En tematisk analyse av forebyggende arbeid mot radikalisering og voldelig ekstremisme i Kristiansand kommune
2021
Master's thesis in Sociology and social work (ME522) Dette er en oppgave som handler om hvordan det forebygges mot radikalisering og voldelig ekstremisme i Kristiansand kommune. Radikalisering som fenomen og «samfunnsproblem» har noen særegne karaktertrekk som gjør det krevende for de som arbeider med tematikken. I løpet av oppgaven gir jeg en utfyllende beskrivelse av konkrete tiltak, ressurser og hvilke stillinger som er sentrale i det forebyggende arbeidet i kommunen. Jeg bygger et teoretisk rammeverk ut ifra en strukturell tilnærming med fokus på henvisningsmekanismer mellom aktører, etater og institusjoner i samfunnet. En individualistisk tilnærming rettet mot enkeltindividets sårbarhe…

Article also available from publisher: http://dx.doi.org/10.1109/EW.2009.5357990 Wireless mesh networks are expected to play an important role in the next-generation wireless communication systems as it can provide wide coverage and scalable broadband Internet access services. However, as more traffic is injected into the network it may lead to throughput degra…
A system-level power saving approach for cellular networks with microcells/picocells
2011
Accepted version of an article from the book: 2011 2nd International Conference on Wireless Communication, Vehicular Technology, Information Theory and Aerospace & Electronic Systems Technology (Wireless VITAE). Published version available from IEEE: http://dx.doi.org/10.1109/WIRELESSVITAE.2011.5940872 Network power consumption reduction has recently become an active research topic. In this paper, we propose a novel approach to save power consumption of a three-cell microcellular network. When the traffic load in the middle cell is low, it can be switched-off and its users are covered. This is enabled by increasing the transmission power of one sector antenna in the two neighboring cells. N…
Greedy versus Dynamic Channel Aggregation Strategy in CRNs: Markov Models and Performance Evaluation
2011
Publishes version of a paper from the book: Networking 2011 Workshops. Also available f rom the publisher on SpringLink:http://dx.doi.org/10.1007/978-3-642-23041-7_3 In cognitive radio networks, channel aggregation techniques which aggregate several channels together as one channel have been proposed in many MAC protocols. In this paper, we consider elastic data traffic and spectrum adaptation for channel aggregation, and propose two new strategies named as Greedy and Dynamic respectively. The performance of channel aggregation represented by these strategies is evaluated using continuous time Markov chain models. Moreover, simulation results based on various traffic distributions are utili…
Medium access in cognitive radio networks: From single hop to multiple hops
2012
Doktorgradsavhandling i informasjons- og kommunikasjonsteknologi, Universitetet i Agder, Grimstad, 2012 If channel assembling is enabled, this technique can be utilized for potential performance improvement in CRNs. Two use cases are envisaged for channel assembling. In the first use case, the system can accommodate parallel SU services in multiple channels, while in the second use case, the system allows only one SU service at a time. In the use case where parallel SU services are allowed, various channel assembling strategies are proposed and modeled in order to investigate their performance and to acquire better comprehension of the behavior of CRNs with channel assembling. Moreover, the…
“Sven and the Media Portal” : A Nomadic Use Case for the Extended Home
2006
The Networked and Electronic Media Technology Platform (NEM) [5] states that users will consume an “innovative mix of various media forms, delivered seamlessly over technologically transparent networks, to improve the quality, enjoyment and value of life. [6] visualizes a future use case and some of the challenges that need to be addressed before the NEM vision becomes reality.
A continuous-space analytical approach for relay node placement in hybrid cellular and ad hoc networks

Article also available from publisher: http://dx.doi.org/10.1109/ISWCS.2009.5285305 A hybrid network is composed of a cellular component and an ad hoc component connected by a relay node, for the purpose of coverage extension and/or capacity improvement. In this paper, we analyze the capacity of such a hybrid network by employing a continuous-space analytical …
Remote service usage through SIP with multimedia access as a use case
2007
The IP Multimedia Subsystem is under deployment, as an IP-based service control and access infrastructure, but how it interconnects with residential appliances is currently unclear. With IMS access for the residential appliances they can be used as both service consumers and service providers. In this paper we present a protocol which allows residential services to be remotely invoked, through the IMS, and consumed in a different network, along with a prototype implementation and early results. With our protocol services of two distinct service protocol systems can cooperate.
