Omvandlingen av en skrivbordsapplikation till en webbapplikation
This thesis investigates how a developer can move a desktop application to the web environment. The investigation also includes finding out what are the limitations of a web application and what is not possible to move to the web from the desktop. The question is whether there is any functionality that is gained or lost in the web application after the move.A survey has been conducted to find out what types of problems occur when moving an application from desktop to the web. The authors of this thesis have developed two prototypes for a company who wants to move a limited part of their current desktop application to the web in the future. The prototypes have been developed in Silverlight and ASP.NET.The survey has revealed that one of the disadvantages of web applications is the difficulty in working with local files and Hardware on the computer.
Automatiska GUI-test : En teoretisk och praktisk studie för hållbarare test
To automate software testing is an investment, and that makes it important to have good knowledge about automation before an implementation is made. In this master thesis a study about automated testing is carried out. The study also includes a closer look at the testing tool TestComplete. TestComplete is one out of many tools on the market that is developed for automated GUI testing and the goal is to get a picture of how well the tool can adjust to CC Systems own applications. Studies show that it is hard to write lasting test scripts.
Test platform for pump controller - Platform development
I detta exjobb har en testplattform skapats för att kunna testa, utvärdera och jämföra olika pumpstyrningar i torr miljö. Testplattformen består av en simulerad pumpstation till vilken befintliga pumpstyrningar av valfri modell kan kopplas, det vill säga ett Hardware-In-the-Loop-system. De främsta fördelarna med en sådan plattform är flexibilitet, snabb feedback samt möjligheten att återskapa exakt samma förutsättningar för olika pumpstyrningar.Testplattformen har implementerats i LabVIEW på en PC som kommunicerar med pumpstyrningshårdvara via ett I/O-kort för analoga och digitala signaler.Det simulerade systemet konfigureras genom val av bland annat pumpar, pumpsump, inflöde och rörsystem. Utifrån de inmatade värdena och styrsignaler från pumpstyrningen simuleras sedan bland annat systemets flöden, energier och temperaturer. Nivån i sumpen, och övriga insignaler till pumpstyrningen, återkopplas från simuleringen.
Mobila plattformar och handhållna enheter : Framtida möjligheter och industriella tillämpningar
The usage possibilities of mobile platforms and smart phones are increasing rapidly as they provide support for better processors, sensors and communications capabilities. This has for many companies resulted in an increased interest to explore the possibilities of mobile platforms and how they can be integrated in various business areas. As the usage of mobile platforms in industrial applications is a new area, it is difficult for companies to estimate their potential, and what contributions the different platforms can give.This master thesis investigates the possibilities and limitations for the consultant firm Combitech when integrating mobile platforms and handheld devices in industrial applications. This is accomplished through a comparison between the platforms and by considering the possible areas of use for the mobile platforms based on experiences from companies and research in the area.For a company with the intent to deliver services that use mobile platforms, it is important to be able to combine expertise and resources to effectively attract customers. The mobile platforms will, if applied right, give great possibilities in industrial applications as a cost-effective alternative for both Hardware and software solutions for businesses, which provides an opportunity to sell services to both established and new clients.

Visualisering av Flight Recorder-data i Saab 2000 avionikrigg
The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with Hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.

Kontinuerlig RFID-detektering för batteridrivna system
This report deals with RFID systems and how to detect nearby tags with the Mifare standard using only a microcontroller and an antenna circuit.The aim was to investigate whether there was any possibility to continuously search for a nearby tag for a system operated with batteries without compromising the lifespan of the battery. At this time the system would take too long time to wake up and look for a tag to give a satisfactory battery lifespan, which should be done a couple of times every second.The report has two issues, namely:Is it possible to direct the microprocessor to detect and identify a nearby tag after the Mifare standard?What Hardware is required for this to be possible?As the research method to provide answers to the above questions an action research was used. This approach has meant that the group worked on information retrieval, examined existing solutions, tested their own solutions and documented the results.The group examined an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor.

Solcellsdrivning av distribuerade inbyggda system
The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.
Energieffektivitet Hos Dubbelskalsfasader
Today multi-touch technology is the basis for many new techniques designed to improve
interactions with computers and mobile devices. It seems that multi-touch screen interface
makes the user handling very natural in the sense that there is no need for a manual in how to
interact with the object on the screen.
The aim with this paper is to establish a fundamental set of design principles intended
specifically for large multi-touch interfaces. To reach this goal we have implemented a couple
of sub-goals beforehand:
It was essential that we acquired a good understanding of the current state of the multi-touch
interface and the different implementations that exist today. To make this possible we
constructed a multi-touch display, "Rosie". Knowing how the Hardware is produced today will
help us understand the limitations and also the possibilities of the design implementations
today and in the future.
We also needed to devise a sound interaction design process that conveys the modern
designers work.
