ABSTRACT System development has become more and more concentrated on development for the Web and this has resulted in larger target groups. It will most surely continue to be so considering that the Web will be the infrastructure of business and services in the future. A big target group involves that the owner of a system can earn a lot of money from the paying users, but that assumes that the system can meet user needs. If a system on the Web does not satisfy the user?s demands then they will use the competitor?s system instead because it is only a mouse-click away.

The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the Software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

Detta examensarbete har genomförts på uppdrag av Totalförsvarets Forskningsinstitut. Examensarbetet är ett av fyra delprojekt i projektet Telekommunikationer för strid i urban miljö. Projektet syftar till att ge förslag på metoder och utrustning som kan underlätta för soldaten på taktiskt nivå, i Försvarsmaktens insatsförband, genom att förbättra informationsinhämtning och -överföring.Syftet med examensarbetet är att i en praktisk demonstration visa nyttan med MIMOsystem antingen genom ökad kapacitet eller genom ökad tillgänglighet.Examensarbetet är uppdelat i tre olika delar: förstudie, utveckling av teknikdemonstrator i hårdvara samt demonstrationer och presentationer. Demonstratorn är byggd medGNU Radio mjukvara, som körs på två Linux-maskiner, med Universal Software Radio Peripheral som RF hårdvara. För att visa fördelarna med MIMO har spatiell diversitet implementerats i en mottagare.Implementationen visar att bitfelshalten reduceras till en tredjedel jämfört med en SISOmottagare..

Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new Software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.

Rapporten beskriver funktionen och implementationen av ett mjukvarusystem utformat för att hämta och presentera data från Internetanslutna sensorer. Idén bygger på ett koncept av Jerry Lindblom vid EISLAB på Luleå tekniska universitet. Utvecklandet har skett i nära samarbete med Gema Industri AB med målet att möjliggöra användning av systemet för övervakning av elmotorer och remdrifter i industrier, men detta är bara ett av de möjliga användningsområdena. Systemet gör det möjligt för användare att skapa webbsidor som kan innehålla dynamiskt skapade grafer utifrån mätdata som tidigare insamlats från sensorer. Tillvägagångssättet är användbart i en mängd olika tillämpningar.

The maintenance phase within Software projects is typically very expensive in terms of resources. The activities of this phase are largely focused around some form of modification of program code. This leads one to consider if there are alternative methods of code production that results in code that allows for less costly modifications. This thesis has its basis in a subset of those concepts which research has shown to provide more flexible code. Once this subset is established, connections are made between the concepts within the subset and claims of benefits provided by the use of Test Driven Development (TDD) methodology.

MindMe is an aid for people with cognitive memory impairments. The aid is completely new and has beendeveloped within this bachelor thesis, no product of this nature could be found on the market before. Theidea came from Niclas Jarhäll, CEO of Mutual Benefits. Mutual Benefits were also partners in the project.The project was carried out by us in cooperation with Bachelor of Science in Innovation Engineeringstudents Malin Albertsson and Victoria Hedman at Halmstad university. The aid consists of a mobile phoneand a number of tags.

The aim of the study has been to see if there are cultural differences in the perception of health and, if so, analyze if this is something needed to be taken in consideration in Swedish healthcare, schools and so forth.The participants were children aged between nine and nineteen. The study was performed at Islamic center's Islamic free school in Rosengård, Malmö. We have used a phenomenological approach that encourages the participants to talk freely and in their own words about a given subject, in our case, health. To analyze the transcribed interviews we have used Software, Minerva, an application of Meaning Constitution Analysis (MCA) developed by Roger Sages, lector at The University of Lund.The results show that all the participants, regardless of culture, feel that eating right and exercising are crucial for their health. Additional to this we have found that the participants have a very strong solidarity whit their family and their origin country.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation Software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

This study has been conducted in order to determine the existence of predictability for the Stockholm stock exchange. With this purpose the random walk theory has been raised against the theory of mean reversion in order to determine which theory is the most substantial. Data has been collected from Nasdaq OMX Nordic and furtherly been processed using the statistical Software EViews. Swedish listed companies? daily share values between 2000-2014 have been analyzed using two tests; an Augmented Dickey Fuller test and a Variance Ratio test.

Systemutveckling har på senare år rört sig mot allt mer flexibla metoder för att bedriva utveckling, ett agilt förhållningssätt vid systemutveckling i dagens IT-bolag är inte alls ovanligt. I takt med förändring av tillvägagångssättet har även ett moment inom testningen fått allt mer fokus: Testautomatisering. Vissa författare hävdar till och med att det inte går att bedriva agil systemutveckling utan att införa testautomatisering. Syftet med uppsatsen är därför att undersöka vilka utmaningar en testare inom de agila metoderna stöter på vid testautomatisering. Detta utförs med hjälp av intervjuer på fem olika företag av fem olika testare där de alla har en gemensam nämnare, att de jobbar agilt..

To save energy it?s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth.

The aim of the study was to distinguish if there was a difference between how work is perceived and how unemployed are viewed by people in collectivistic and individualistic cultures. A phenomenological approach was used in order to capture the participants life-worlds and their meaning constitution of a phenomenon, in this case the meaning of work and how unemployed are viewed. Subjects from different parts of the world, belonging to either a collectivistic or individualistic culture, participated in this study. Data was collected by self-reports which were analyzed by the method of MCA (Meaning Constitution Analysis) and the Software Minerva. The results indicated that there were differences in how individuals from collectivistic cultures compared to individuals from individualistic cultures reflected about the meaning of work.
