We have 3G on the doorstep but nothing seems to attract ordinary people to this technology. To attract the mass market the telecom industry must show something beyond high bit rates. They must show how ordinary people can take advantage of this new technology. This is done by showing the possibilities of the new technology and by demonstrating applications that it will handle. The telecom industry must convince the telecom operators to invest in this technology and the only thing that matters to them is how much revenue they can make by adopting the upcoming technology.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

The aim of this thesis is to examine young adults? attitudes towards libraries marketing in social media. Libraries mainly use social media to reach out to young adults. However, young adults mainly use social media to communicate with their friends. The question that arises is if young adults are interested in communicating with organizations such as libraries on social media.

PDF-files are to become a native file format in all prepress supplier workflows during 2006. This will give an opportunity to automate and develop a more stream lined prepress workflow. It is desirable to secure digital files by preflight the files early in the process. The objective with this project is therefore to find software that can automate parts of the preflight process and also to build up a well-functioning preflight workflow for preflighting both PDF-files and native files.Meetings have been held with preflight suppliers to find a solution for how to automate parts of the preflight in the prepress workflow. Seven preflight software companies demonstrated the possibilities with their products and four of these were chosen for continuing working with.

Purpose: The purpose is to research different co-operations between venue owners and WISPs, when WLAN is deployed in a public space. The aim is to establish viable business models for the interaction between the two vital actors in the public WLAN industry. In this work, the advantages and disadvantages of revenue and cost sharing will be defined, along with technical and commercial issues that need to be resolved. Methodology: A number of case studies of the current situation have been conducted in the most attractive venues for WLAN, airports. As the public WLAN market had most widespread adoption and is most mature in the USA, case airports were chosen both there and in Scandinavia.

Syftet med uppsatsen har varit att genom kvalitativa intervjuer lyfta fram motpolerna kringdagens konsumtion av digital underhållningsmedia och fastställa om konsumenters syn på värdekan relateras till deras val av att antingen betala för ägandet eller för tillgänglighet av den. Metoden har bestått av åtta stycken kvalitativa intervjuer där respondenter fått frågor om sinkonsumtion av digitala underhållningsmedia inom; musik, video, spel och podcasts. Uppsatsen kommer fram till att konsumenter ser värdet i användningen av mediet och inte iägandet av det. Konsumenterna vill således hellre strömma sin media än att ladda ner den. Deväljer därför mer eller mindre obehindrat den tjänst som har bäst utbud.

Forestry affects most of the forest-covered land in Sweden. In the landscape, the most common stream type is headwaters, which are important sites for many processes and organisms in both the terrestrial and the aquatic ecosystems. The aim of this study was to investigate how the abundance of benthic invertebrate functional feeding groups in headwater streams develops after clear-cutting and if it also is possible to detect a change in the composition of feeding groups. The study also attempts to determine what factors have an effect on temporal changes in abundance of these groups. For the study, 11 sites in northern Sweden were sampled for benthic invertebrates using a Surber-sampler, and for each site canopy-cover and pH was obtained.

The purpose of this study is to find datable interstadial sediments in the core area of the LateWeicheslian ice sheet extent. Based on geomorphological evidence, three coring sites wereidentified close to the Ultevis plateau in Norrbotten, northern Sweden. Sediment coring wascarried out in two pre-Late Weichselian stream channels and in a sediment basin. Stratigraphyfrom one of the sites, a 100 meter wide meltwater channel, was chosen for further analysis. Thestudied core was 5,93 m long and ended in a lower till unit.

During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.

På grund av en ökad befolkningsmängd och nya tekniker som gör fler sjuka går att bota ställs nya krav på svensk sjukvård. Sjukvården måste möta de nya kraven med ett bättre effektivare resursanvändande och där till krävs nya förbättringsmetoder. Med influenser från industriell tillverkning har sjukvården omarbetat lean production för att skapa ett universellt förbättringsverktyg som lämpar sig för vårdorganisationer. Verktyget kallas lean healthcare och är omdiskuterat och dess effekter tvetydiga. Att undersöka om och hur värdeflöden i en akutmottagnings triage, som innebär en prioritering efter patienters allvarlighetsgrad, kan effektiviseras med hjälp av ett flödesorienterat arbetssätt som lean.

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.

Environmental management systems are a way of systematizing and streamlining an organization's environmental efforts. Within its EMS the organization determines it´s environmental policy and various environmental objectives. In order to achieve their environmental objectives the organization produces action plans that describe how they will work towards the objectives. Stora Enso Skog AB´s districts have been assigned to produce action plans for the company´s environmental objective of 90 % approved everyday nature consideration in final felling and any targets included within this objective. The purpose of this study was to investigate how the districts work with these action plans and how this could be improved.
