Hur kan mobila användare studeras? Frågan blir allt mer aktuell i samband med att vi människor i större utsträckning blir mobila och därmed också använder mobila artefakter som en del av vardagslivet. Denna fråga är framförallt aktuell för de företag som utvecklar denna typ av artefakter. Vi har under detta kandidatarbete samarbetat med ett företag som dagligen ställs inför denna typ av frågor, och vi kommer i denna rapport behandla utvecklingen av en metod för att studera just mobila användare. Att studera användarna är naturligt, då det är de som är nyckeln till vilka tjänster och artefakter som just de har användning för.

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security. In order to study usability, a test group of ten persons have been used to evaluate the usability of the system.

The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

This thesis presents a general definition of science education and earth science education.An inventory has been conducted of published material during the years 2011-2013, withthe start in 2013 and working backwards for international publications and with no timelimits in time for Swedish publications. Different databases were used during April 2013 forthe inventory.The thesis organizes and analyses published material in earth science education in a tablewith a following discussion.The purpose with the inventory was to investigate the amount and content ofprevious year?s publications in earth science education. Concept inventories were foundto be the most common subject of the found material, followed by virtual field studies. Thelargest amount of publications was published in North America.

Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.

The aim of my study is to investigate if and in that case how the writing process and texts written by students in the upper secondary school are affected by the writing tool; does it matter if they write their texts on a computer or by longhand? Another objective is to compare such an effect with the findings of previous studies performed on earlier generations of writers. The first part of my study was a survey. It showed that two thirds of the 67 students participating thought that they would have written better texts in the national writing test if they had been able to use computers. In the second part of the study each of the fourteen participants wrote one text on computer and another by hand.

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.

Pipe replacements with bathroom renovations are complex construction projectshighly dependent on the construction work carried out in the residents? homes whilethe residents still live there. This fact makes the flow of information from contractorsto the residents of an important success factor. In the current situation thecontractor, Aros Bygg & Förvaltning AB, notifies the residents? information throughpaper notification, which gives managing the work involves a lot of paper work.This thesis examines whether and to what extent the contractor may replace thepaper notification with a web-based information channel.

The purpose with this report is to illuminate the construction solutions and the deformations that could exist in medieval parish stone churches. But also to increase the writers understanding how activity forces effect the construction of the churches. With help from literature and a practical study, containing three churches the writers have collected the material that the conclusions and discussions are built upon in this report. The construction of the churches consists of three parts, the wall, the roof and the vault. The construction solutions are similar in the churches disregard of the roof, where the roof trusses are different.

Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.

Med denna uppsats vill vi ge läsaren en uppfattning om vad Free Software och OpenSource (FOSS) handlar om och mer specifikt analyseras huruvida FOSS kan fungera ien kapitalistisk värld eller inte. Den grundläggande idén med Free Software ochOpen Source, eller fri programvara och öppen källkod, är att ge varje användare avett datorprogram rätten att fritt köra, undersöka, ändra och vidaredistribueraprogrammet.Författarna ställer i uppsatsen frågan ?Hur kan pengar tjänas på FOSS?. Uppsatsensyftar till att försöka bena ut denna frågeställning. Frågeställningen ger upphov till tvåperspektiv; dels i meningen ?på vilka sätt kan man tjäna pengar på FOSS? och dels ibetydelsen ?hur kommer det sig att det går att tjäna pengar på FOSS då det är gratis?.Uppsatsen knyter an till litteratur kring FOSS samt ekonomisk teori och är främstteoretisk till sin natur.I uppsatsen visas att gamla beprövade affärsmodeller inte kan användas rakt av förföretag som använder eller utvecklar produkter baserade på Open Source.

This study highlights the importance of computer technology and its impact on elder care staff's skills development in the public sector. The government presents the digital agenda within which information and communication technology today is considered to have a potential for sustainability, growth and development. According to the EU Commission, there are several important elements that should be improved to digitize the workplace. Among these are digital literacy, collaboration between agencies and increased investments in research, education and innovation. New technology can be understood in different ways by individuals, some see the computer as something positive and exciting, while others may find it hard to see the opportunities for learning and development.
