This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Den här uppsatsen behandlar mobilmarknadsföring och ämnar svara på frågan om hur lämplig mobiltelefonen egentligen är som relationsmarknadsföringskanal. Vi har funnit de metoder som är vanligast förekommande för att sprida reklambudskap och jämför hur bra de uppfyller kraven för att vara relationsskapande. För att utröna detta har vi intervjuat branschkunniga personer från två av landets största mobiloperatörer samt personer som arbetar på nordiska mobilmarknadsföringsbyråer. För att mäta styrkan hos mobilmarknadsföring som relationsfrämjande marknadskanal har vi genom modeller från relationsmarknadsföringen skapat ett eget ramverk vilket vi applicerat på olika marknadsföringsmetoder via mobiltelefonen. Resultatet av vår studie visar på att mobilmarknadsföring kan användas för att bygga långsiktiga, ömsesidiga och vinstgivande relationer, vid rätt användning.

This report is the result of a thesis as been implemented during the spring term 2009 atthe University of Gävle.The company Bruks produces mobile chippers which are used for chipping loggingslash, roundwood and parts of trees. The chipper is powered by a separate diesel engineand the chipper can be assembled on trucks, trailers or some other carrier vehicles.When the chip has passed the chipper drum, the chip is collected in an integrated binwhich is mounted on the vehicles frame with dumping yokes. When these dumpingyokes were designed they were probably created with large material dimensions. Theaim with the degree project is hence to study the strengths of materials and, if possible,to suggest an arrangement that can decrease the total weight on the dumping yoke onBruks´ mobile chippers 805 CT.The CAD-program Pro/ENGINEER was used during the project for outlining the 2Ddrawings,as distributed of constructors on Bruks, to solid 3D-parts. The three-dimensionalassembly from Pro/ENGINEER was transferred to Pro/MECHANICA.

Unemployment and long term unemployment is a reality for a large number of people in Sweden. This may be the result of structural changes in the labor market, but involves a wide range of issues. Along with other actors, the social services are obliged to support the long term unemployed to find a job. The aim of this study was to describe and analyze the work done by social workers towards the long term unemployed, 25-49 years old, in two municipalities. We performed altogether six qualitative interviews.

Web Services har vuxit i popularitet de senast åren. Användningen av inbyggda systemökar också ständigt, och möjligheten att göra inbyggda system tillgängliga via Web Services öppnar nya möjligheter.Detta arbete visar på möjligheter och problem med standardiserade textbaserade protokoll för kommunikation i inbyggda system med små resurser. XML-RPC och SOAP studeras ur detta perspektiv. SOAP befinns vara mer komplext att implementera stöd för än XMLRPC i den begränsade testmiljön, som har 32kB internminne. XML-RPC visar sig ge fördelar över proprietära protokoll främst när det gäller underhållbarhet och återanvändbarhet..

The purpose of this study was to analyze and develop a workflow for assessing and representing the value of ecosystems to professionals involved in municipal planning. A thorough literature review was conducted and supplemented by interviews and observations. Frameworks for ecosystem service assessments were analyzed and combined with methods in urban planning in order to assess social and ecological conditions. A workflow was set up and methods were evaluated by applying them to a case study in the area Åstråket in Uppsala. Experience from the case study was compiled in order to improve the workflow.Complex assessments were identified and simplified for the method to be useful for practitioners.

The ever-changing modern health care environment places high demands on leadership skills. The purpose of this study was to describe the causes that effect leadership within the health care services carried out in a municipality. Data was collected by interviewing four health care managers, three registered nurses, eight enrolled nurses and one auxiliary nurse. A qualitative approach based on a content analysis method was conducted in the analysis of the interviews. Latent content deals with relationship aspects and interpretation of deeper underlying meaning of text.

The thesis describes the following main question: Will the administrative labour during football tournaments be made easier with the help from a mobile web service or will it convey to unnecessary extra work? To be able to give a good and qualified answer to this question, the thesis will in the beginning describe how the technique for such a system might look like and also describe the existing administrative moments during a football tournament, this is too give the reader a deeper understanding for further reading. The thesis then goes on to describe a concrete system which is tested on three football tournaments. On the basis of the tests, interviews and through analysis of these the thesis will be able to answer our questions. The result which we present in the thesis have unfolded through testing of the system on three chosen football tournaments. The differences in way of labour pre and post the system have been analyzed and through interviews the value of these changes have been assessed. The results achieved in the thesis are as follows, the presented mobile web service does not only decrease the total work effort made by the tournament officials it also speeds up their work.

Service Design is a relatively new, unexplored and exciting phenomenon that through an interdisciplinary work methodology designs services. A discussion has been going on for a long time regarding whether there is a difference between products and services. Services are often classified as immaterial, heterogeneous, non-storable and inseparable in relation to products. A question that arises is if something specific characterises the work methodology used regarding service design. The aim with this paper is thus to explain the work methodology when working with service design.

Mobilmarknaden idag består av ett antal aktörer, Nokia är störst, med Samsung, Motorola, LG, Sony Ericsson och HTC bakom sig. Nokias telefoner bygger på operativsystemet Symbian som idag är det största operativsystemet på marknaden för smartphones. Open Handset Alliance har utvecklat ett eget operativsystem för främst mobiltelefoner, kallat Android, som är bygger på Linuxkärnan. Android är framtaget som ett gratisalternativ till de dyra konkurrerande operativsystemen.Examensarbetets syfte är att studera utvecklingsmiljön till Android och se vilka kunskaper som krävs för att effektivt kunna utveckla applikationer. I detta ingår även att identifiera vilka möjliga problem som kan uppstå under utveckling, samt dokumentera vilka utvecklingsverktyg som finns tillgängliga. Målet har varit att utreda hur applikationer utvecklas effektivt, det innebär att ta reda på svaren till vad som krävs av utvecklare för att kunna utveckla applikationer, vilka utvecklingsverktyg som finns, samt vilka problem som kan identifieras under utveckling.

The purpose of this study was to examine domestic adoptions in Sweden, and also compare the Swedish adoption system to the Canadian adoption system. I wanted to find out why there are so few domestic adoptions in Sweden, and how it has changed over the years. I also wanted to know why there is such a large difference between Sweden and Canada regarding adoptions.I interviewed five social workers to find out what attitudes the social services have regarding adoptions. My other questions were how the childs best interest is considered when a parent wants to place a child in an adoptivefamily, and which parents decide to place their child instead of keeping it.I found that the social services are reluctant to place children in adoptivefamilies because their main goal is to keep biological families intact. In Canada the social services goal is to provide the child with a safe and stable home.There is no longer any stigma surrounding single mothers and well developed welfaresystems enable most to keep their children.

The EU Services Directive has caused an intense debate across Europe. Its purpose is to remove obstacles to trade and to open up the public sector to increased competition. The Swedish labour movement has been deeply involved in the policy process, and union leaders have proclaimed the compromise reached in the European Parliament in April 2006 as a success.In the paper two major aspects have been considered: the meaning of the Swedish model and the process of Europeanization. The Swedish model previously allowed for a strong labour movement, through a social democratic hegemony, but the EU membership has implied new conditions for union influence. The paper examines how this change has affected the strategic choices of the Swedish labour movement, and how it has been manifested in the union's work with the Services Directive.

The purpose of this study is to use a qualitative approach to get an understanding of what is expected of social workers targeted towards women managers in social services. Nine social workers were interviewed. The empirical data was then analyzed on the basis of gender theory. Respondents did not see their supervisor as a manager but more as a social worker with special tasks. Our empirical data indicates that there is a strong belief that men and women possess different properties.

Despite the fast growing development of IP-telephony services, only a small number of people in Sweden use them. Of the total amount of fixed telephony subscriptions, maximally five percent are based on IP-technology. Through an exploratory study, the main purpose with this thesis is to identify factors that influence the use of IP-telephony on the consumer market, and the factors? internal relationships. The thesis also has two sub-purposes: firstly, chart the supply of IP-telephony services and secondly, discuss what IP-telephony services that are requested by today?s customers in the future.
