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).

Syftet med undersökningen var att undersöka vad dagens ungdomar har för värderingar och förväntningar till det kommande arbetslivet. Teorier tar upp ungdomsarbetsmarknaden som försvårar för ungdomarna att få arbete. Värderingarna bland ungdomarna har påverkats av deras uppväxt och ett individualiserat tankesätt har utvecklats. Arbetet ska innebära mer än bara en försörjning, det ska vara en del av identiteten. Det viktigaste på en arbetsplats är bra arbetskamrater och roliga arbetsuppgifter.

Detta examensarbete omfattar generering samt vidareutveckling av koncept av en infästning för ett muckhanteringssystem på en tunnelborrningsmaskin. Maskinen, som går under arbetsnamnet Mobile miner, utvecklas av Atlas Copco tillsammans med bland andra konsultföretaget Svea Teknik AB. Examensarbetet genomförs parallellt med slutskedet av det verkliga utvecklingsprojektet och kan eventuellt komma att inkluderas. Examensarbetet har föregåtts av utvecklingen av tunnelborrningsmaskinen och dess främre muckhanteringssystem som består av en ramp (apron) och en kedjetransportör. Systemets uppgift är att samla upp och transportera bort den bergskross (muck) som genereras vid själva borringreppet.

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.

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.

Titel Reklam i mobilen? En studie av förutsättningar för tidningsföretag att använda mobiltelefonen som marknadsföringskanal Författare Beata Jungselius Kurs MK1500 - Examensarbete i Medie- och kommunikationsvetenskap Termin VT-09 Uppdragsgivare Dagspresskollegiet Handledare Oscar Westlund Syfte Att studera förutsättningarna för tidningsföretag att använda mobiltelefonen som marknadsföringskanal. Metod Omvärldsanalys med hjälp av analysmodellen PEST samt intervjuer Huvudresultat Mobiltelefonen som marknadsföringskanal har visat sig vara väl lämpad för olika former av marknadsföringsåtgärder för tidningsföretag. Särskilt väl kan den antas fungera för tidningsföretag som utlåter annonsutrymme i form av så kallade reklambanners på sin mobilanpassade webbsida då dessa i regel ger ett högt observationsvärde såväl som en hög klickfrekvens. SMS-utskick kan även de fungera väl, förutsatt att mottagaren gett företaget tillåtelse att kontakta dem på detta vis helst på eget initiativ.

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.

The Swedish traffic system is congested, especially in the urban areas; travellers face daily growing traffic jams and delays in public transport. In a congested traffic system, travellers need support to make smart and sustainable decisions and one such tool is traffic information.One issue today is that too few travellers use traffic information in support of their travel. Research shows that travellers would see great value in receiving the information; however current systems do not meet their requirements. This is a problem since the society would benefit greatly from a well functioning traffic information system.In this report, a number of channels that can be applicable for providing traffic information will be explored, with particular emphasis on interference information.The information channels are analyzed based upon the needs and requirements of the society and the traveller. The thesis of the report is: the more of these needs and requirements are met in a channel; the better is the channel to use for traffic information.

Det blir allt vanligare att utveckla mobilapplikationer för flera plattformar parallellt, samtidigt ärden information som finns tillgänglig för metoder av detta slag knapphändig.Rapporten beskriver utvecklingen av en mobilapplikation till flera plattformar. Det verktyg som använts är ramverket PhoneGap, med hjälp av PhoneGap kompileras en webbapplikation till en mobilapplikation. Det innebär att en webbapplikation utvecklas med hjälp av verktyg somHTML5, CSS3 och JavaScript. För att få en ?mobilkänsla? har ramverk som jQuery Mobile använts.

Den teknologiska utvecklingen har under de senaste decennierna fa?tt en allt sto?rre betydelse i samha?llet. Som en naturlig fo?ljd av detta har bankernas verksamhet fo?ra?ndrats, bland annat genom o?kat utbud av tekniska tja?nster och produkter. Tidigare studier pa?visar att ma?nniskans beteende har fo?ra?ndrats i takt med samha?llets utveckling och ma?ste idag va?nja sig vid att allt mer kommer att hanteras via de teknologiska distributionskanalerna.

The bank market for farmers in Sweden is dominated by Swedbank and Landshypotek. One of the most aggressive challengers is Länsförsäkringar Bank, which in 2009 had seven per cent of the Swedish bank market for farmers, but 57 per cent of all new lending. This paper deals with the problem of new banks to break into the bank market where farmers are slow in terms of change in their attitudes and loyal to their banks. The study has been carried out in cooperation with Länsförsäkringar Gävleborg which is a new actor in the banking market and thus eager to take part in the outcome of the study. This essay thus seeks to examine the attitudes farmers have against bank switching and the factors that influence their choice of bank.

Background and problemThe Swedish mobile market is highly competitive despite the oligopoly that currently exists. A short product life cycle together with fads and new innovations puts pressure on the operators to respond to the ever changing environment and to develop and adapt their strategies after it.As a previous study regarding a specific operator?s strategy was cancelled due to the extensive confidentiality surrounding it, an interest was sparked to perform an industry analysis as this is clearly something the actors spend a great deal of time on developing. The launch of the 4G network will offer new opportunities for the operators regarding products services. It may also impact the competition on the overall market.PurposeThe purpose of this thesis is to present a deep analysis of the industry and give the reader a comprehensive picture of existing conditions.

In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.
