Technology has grown rapidly in recent years. At present, almost all social interaction are through computers and telephones. It is, however, not everyone who can manage these media. This applies mostly to elderly people who have not kept pace with technological developments. A major contributing reason is that the manuals are usually bulky and too technical for this group.The purpose of this paper is to develop a concept/prototype into a product that will facilitate the use of mobile phones for seniors.

In the light of new technology health care is now given the opportunity to form a more mobile way of working that would bring about potential gains in terms of efficiency and quality. On the other hand, a more mobile health care also requires a more generous handling of personal information, something that may raise issues in terms of privacy. This study shows that the privacy of the patient requires two things: (i) that the personal information of the patient is handled in a way that generates her an overall positive expected utility and that (ii) the negative expected utility that each risk of an information leakage causes is offset by the expected utility it also makes possible. The first requirement (i) is shown, in comparison with today?s way of working, to be met due to the potential gains in efficiency and quality in combination with no increase in the probability of informational leakage or negative effects of such a leakage. The second requirement (ii) was also considered met since no separate risks of information leakage could be identified that was not offset by the gains it made possible in terms of expected utility..

Användningen av GPS-teknik har på senare år tagit ett stort steg framåt. I dag finns den inbyggd i våra datormobiler som inte sällan rapporterar var vi befinner oss. I denna uppsats undersöks hur datormobilanvändare påverkas av datormobilens inbyggda GPS.Teknik utvecklas ständigt, det som var nytt i går kan kännas gammalt i dag. De senare åren har försäljningen av datormobiler expanderat kraftigt. I takt med detta har Internet blivit något som människor ständigt bär med sig.

Tidigare forskning har visat att systematisk självrapportering är en fördelaktig metod för att följa enpersons psykiska mående över tid, och att en digital mätmetod i sin tur skulle innebära många praktiskafördelar jämfört med en analog. Detta är en experimentell randomiserad, kontrollerad studie som medutgångspunkt i personcentrerad vård och spelifiering undersöker 35 personers användarfrekvens ochattityder efter en tvåveckorsperiod där hälften har fått prova att självskatta sitt psykiska mående via enmobilapplikation, och hälften fått göra detsamma via ett analogt stämningsformulär. Resultatet visar enhögre användarfrekvens bland deltagarna i mobilapplikationsgruppen, samt ett uttalat intresse hosbägge grupper för digitala metoder för självskattning av psykiskt mående. Bägge metoderna ansesstärka personcentrerad omvårdnad. The aim of this study is to explore user frequency and attitudes for persons using a mobile applicationfor assessing mental health compared to persons using an analogue assessment method.

This master thesis includes a description of how a number of sensors are put together in a sensor platform. It also gives a description of how localization and mapping has been performed with data collected from the sensor platform. Localization is a prerequisite for most of the tasks that can be requested from an autonomous mobile robot. In many situations the GPS signal is not available and hence an additional localization system is required. One approach is to apply localization based on landmarks extracted from the robots surrounding.

The number of text messages sent from mobile phones, has increased dramatically over the last few years. Along with that, we are witnessing a lot of new mobile portal services currently being developed. Many of these services rely on an ability to input text efficiently. The traditional phone keypad is ambiguous because each key encodes more than one letter. At present, the most common way to deal with this problem is using a stored dictionary to guess the intended input.

Corporate Social Responsibility (?CSR?), även på svenska kallad företagens samhällsansvar, har under de senaste åren fått en allt mer betydelsefull roll i företag. Det är av intresse att studera hur olika företag ser på och använder sig av CSR, då CSR står för hur ett företag tar sitt ansvar jämtemot sina intressenter. Detta ansvar kan vara socialt lika väl som miljömässigt. Syftet med denna rapport var att analysera och undersöka vilken påverkan Sony Mobile Communications CSR initiativ GreenHeartTM hade på koldioxidutsläppen i en livscykel av deras produkter.

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.

Through the entry of web 2.0 the technologies behind web development has changed dramatically. Asynchronous JavaScript and XML (AJAX) is the umbrella term for different techniques that make it possible to build rich and interactive user interfaces in today?s web browsers. Service Oriented Architecture (SOA) describes how common services can be bundled and published so they can be consumed by different systems.The company SYSteam Evolution AB, which has requested this project, wanted a web application that shows a graphical activity chart in order to easier view ongoing projects. The goal for this project is to develop a demo platform that shows how AJAX and SOA can be used to create flexible and reusable applications.
