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.

AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined  how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.

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.

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.

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.

Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.

Background: The dependency on knowledge and competence today is more critical than earlier. Today, companies need to put more effort into identifying and filling knowledge gaps, which can be achieved through mergers and acquisitions. It is important that the companies succeed in coordinating their operations after this process of change. Out of a theoretical point of view it can be argued that companies need to balance between different coordination mechanisms that result in standardized and flexible coordination respectively. Purpose: The purpose of this Master Thesis is, in the context of a merger, to investigate and analyze which coordination mechanisms that are used in knowledge-intensive companies, how these coordination mechanisms are combined and what explains the chosen combination.

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.

Globalisation and diversity has increased the presence of different languages in Swedish municipalities. As the local administrative authorities with responsibility for the public crisis management, how are these municipalities coping with crisis communication recipients that are not speaking Swedish? Through an inductive approach, this thesis formulates a theory of crisis communication adaptation by studying Swedish municipalities with a large part of inhabitants with foreign backgrounds. This thesis finds that municipalities that are not adapting their crisis communication to non-Swedish speakers follows a discourse that paints a picture of these recipients as at least understanding the Swedish language. Municipalities that do adapt their crisis communication have drawn lessons from local incidents that complements this discourse.
