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.

Utifrån mina undersökningar och kundens krav och önskemål, har jag planerat och implementerat en färdig virtualiseringsmiljö som baseras på Hyper-V. Denna miljö är uppsatt i ett s.k.

For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.

AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.

Genereringen ska ske i plattformen Softadmin® som används för att bygga alla kundsystem.

Inledning: Epikutantester används för utredning av kontaktallergier. Det görs ca 3000 tester varje år i Sverige som överförs till ett kvalitetsregister.  Målet med projektet var att utveckla en webbapplikation och en underliggande databas för hantering och lagring av ett nationellt kvalitetsregister för epikutantester (The Swedish Patch Register). Databasen skall lagras på en central server lokaliserad på Universitetssjukhuset, Örebro.Metoder: Lösningen blev en applikation för webbläsare programmerad i språket C# med hjälp av Microsoft Visual Studio 2008 och ramverket ASP.NET 3.5. MySQL .NET connector tool 6.2.2 möjliggjorde anslutningen mellan ASP.NET och databasen.

The intention of this essay has been to investigate how the new digital technology has affected the tourism industry and marketing, as well as how travel agents and tour operators adapt to this. We also aimed to get a broader view of how the future might look like when it comes to marketing and virtual service landscapes. We decided to base our research according to these following four questions:? What affect travel agents? way of adoption to the technical development?? What purposes do the travel agents have for building up their virtual service landscape?? How much does the travel agents emphasize on digital marketing?? What can travel agents do to better adapt to the technological development in the future?We have chosen to use a qualitative research for this essay. The reason for choosing a qualitative research was to gain a wider understanding that would represent a big part of the changes of technology development.

This report describes a bachelor thesis work performed at the cloud storage company CloudMe in Linköping, Sweden. The storage service provided by CloudMe allows users to access their files seamlessly from multiple units at the same time. In the cloud there is storage provided for contacts, calendar and e-mail, which is data nowadays normally used by smart phones.Exchange ActiveSync is a protocol developed by Microsoft which, among much more, provides functionality to synchronize the previously described data. This protocol is supported by the smart phone developers and the ability to synchronize over the exchange protocol is implemented in products by default. Due to this fact it would be preferable to implement support for synchronization from CloudMe to phones over this protocol.

Lantmäteriet i Gävle är ett företag som hanterar mycket stora datamängder i databaser och det är därför av stor vikt att de har ett väl fungerande databashanteringssystem. De använder sig av databashanteringssystemet Oracle, men intresse för alternativ finns. Lantmäteriet önskade därför en rapport som jämför deras nuvarande databashanteringssystem Oracle 10.2.0.3 med möjliga alternativ. De databashanteringssystem som i denna rapport jämfördes med Oracle är Microsoft SQL Server 2005 och MySQL 5.1. Aspekter som studerades är prestanda, kostnad, säkerhet, kompatibilitet, tillgänglighet och support.

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Larmet ska vara en box som placeras ut på en strategisk plats för att detektera avvikelser i vibrationer med hjälp av ett digitalt filter. Larmet har ett brett användningsområde för mobila och stationära applikationer. Larmboxen kommer vara ansluten till Internet via en inbyggd mobiltelefon (GPRS). Där finns också en inbyggd GPS-mottagare för att bestämma boxens position.

Denna studie tacklar ett av de problem som modern IP-telefoni brottas med, som gör att det är svårare att konkurrera med traditionell telefoni: fördröjningar på grund av otillräckliga Session Initiation Protocol-servrar (SIP). Genom tester av de viktigaste faktorerna jämförs fyra högaktuella Open Source SIP-servrar: OpenSIPS, Kamailio, FreeSWITCH och Yate. Avsikten är att underlätta valet av SIP-server för nya applikationer inom IP-telefoni, öka prestandan samt snabba på utvecklingen. Studien behandlar de intressantaste faktorerna vid val SIP, såsom användarvänlighet, hastighet, lagring av användardata samt ljudkvalité. Slutsatsen blev att Kamailio stod som klar segrare, med överlägsna resultat i jämförelse med övriga servrar, på de parametrar som valts ut.
