Near Field Communication, NFC, is a short-range wireless communication technology that enables data exchange between devices in a secure way. A NFC phone has the potential to enable the convergence of wallet, phone and keys, but as many other technological innovations, the launch is struggling. We have discovered that technological innovation is only the first step. For an innovation to be adapted, there need to be business model innovation too. Many actors form the ecosystem of NFC and the business model for each service is still an unsolved problem.

In this thesis I'm trying to investigate how good educational computer programs work in elementary school. I delimited the study to contain one elementary school in the stages of 6 to 9. The method I used was qualitative and the approach was inductive. I interviewed four teachers and five pupils as the way to collect data for the study. The theories I used were parts from different books with authors, which have done similar studies and researches.

Following essay discusses the possibilities of using a gender perspective when studying local governance within a Swedish context. Governance is an international concept used to describe a more lose, informal and network based way of doing politics The main purpose for conducting this essay is that traditional theoretical frameworks used in the study of local politics are not enough to fully conceptualize the complexity of our changing political environment.After a broad summing up of what had been done in the recent decades within Swedish political science on the topic of local politics and gender I came to the conclusion that so far nothing had been written on governance. The next step was therefore to conduct a pilot study to cover the subject matter of governance and gender. The study was based upon interviews with five female politicians in Malmoe city.Results showed that governance, in terms of informal networks did exist, and had influence over the local politics. Some of the networks were male dominated.

This case study has been conducted within the Swedish fitness chain World Class to explore the opportunities for knowledge development and transfers within franchise networks. We have interviewed the product manager at the World Class headquarter, the owner of a franchise club and a local product manager from the same facility. Our finding indicates that various forms of knowledge transfer occur within the World Class network, particularly in product development and sales. The transfer occurs within the framework set by World Class with regularly scheduled meetings. In addition informal networks provide other means of knowledge exchange between some units.

I Estland 2007 utbröt vad som kommit att kallas ?Cyberwar I?, vari ett stort antal centrala myndigheters, tillika finansiella institutioners servrar attackerades av massiva så kallade Computer Network Attacks (CNA), utfört av framförallt ryska aktörer. Estland protesterade högljutt, men frågan huruvida CNA är att beteckna som olovligt är allt annat än klar. Prövningen sker mot den folkrättsliga regimen Jus ad Bellum, och huruvida metoden uppfyller vissa centrala begrepp. Men hur skall denna regim appliceras CNA?De frågeställningar som avses besvaras är: hur kan CNA utgöra våld eller hot om våld i enlighet med FN-stadgans artikel 2(4) samt hur kan CNA utgöra väpnat angrepp i enlighet med FN-stadgans artikel 51? Detta avses göras genom en studie inbegripande flertalet folkrättsliga experters teorier på området CNA och våldsanvändning, samt applicering av desamma på en fallstudie av händelserna i Estland 2007.Sammanfattningsvis konstateras att flertalet variabler har bärighet i hur CNA kan uppfylla artiklarnas centrala begrepp, vari frågan om association, effekt, aktör och mål tydligast faller ut.

The purpose of this paper was to investigate the foremost teachers thinking of computers in teaching, how they work practically with computers as a tool, and if it is reflected in the students' school performance. To carry out this study, I used qualitative interviews as a method and I have interviewed four teachers where two works at the high school and two in upper secondary school. Both schools use computers in teaching as a supplementary tool for teaching materials. All teachers have similar ideas regarding what purpose one should use the computer and in which way, but the important thing is that the teachers and students receive an introductory course in how to use computers. Educators agree that this approach is and can promote students' language and knowledge regardless of the subject.My informants have come up with own methods that they use in the digital classroom including Skype, YouTube, Facebook and flippedclassroom where one can learn from other educators working.

The value of an organization?s availability and transparency towards the public whenever and wherever it is necessary has increased. Internet and the social networks have become essential to most of the citizens of Sweden but for organizations social networking still is an area that is relatively unexplored. As the Internet and social media progresses it becomes a greater part of people?s lives, which leads to more demands but also a great amount of possibilities for the organizations that participate in this technical revolution.The purpose of this quantitative study is to examine if and how the people receiving the information published on the Växjö and Alvesta police department?s Facebook-page are considering Facebook as a channel of communication.

This essay is written at the university of Linköping and is a part of the teachers education. The intire essay is available on CD-rom. Its content is directed towards teachers who entirely or partly works, or want to work, in computereducation. The CD-rom contains both textmaterial and presentations, with teacherinstructions, wich are directly appliable in teaching computers. The teachingmaterial on the CD-rom is based on an empiric survey with different computerteachers.

I studien studeras hur komplexiteten kring sociala medier kan studeras, samt pa? vilket sa?tt sociala na?tverk a?r relaterade till na?tverken i sociala medier och hur det pa?verkar konsumenterna. Syftet med studien a?r att underso?ka de sociala medierna i fo?rha?llande till de sociala na?tverken med fokus pa? konsumentbeteende och da?rigenom skapa en generell modell som fo?rklarar problematiken. Studien bygger pa? en litteraturstudie som i fo?rsta hand sammansta?llts av artiklar med fokus pa? a?mnesomra?dena sociala na?tverk, elektroniska sociala na?tverk och sociala medier. En enka?tunderso?kning gjordes fo?r att sammansta?lla konsumenters a?sikter om a?mnesomra?dena, i syfte att tillslut utmynna i en analys och diskussion. Det ga?r att konstatera att sociala medier har vidgat det sociala na?tverket fo?r den enskilde konsumenten. Detta resulterar i att den enskilde konsumenten nu kan komma i kontakt med fler akto?rer och andra konsumenter som i ma?nga fall kan vara oka?nda.

Spelmotor är benämningen på den komponent som hanterar en del av mekaniken i ett datorspel. Förutom funktioner för grafik, fysik etc. finns också funktioner för rörelser, interaktion med världen etc. I detta examensarbete går vi in på hur en spelmotor för morgondagens mobiltelefon kan se ut, samt vad dagens mobiltelefoners hårdvara och mjukvara saknar för att dagens PC-spel ska kunna portas till dem. Stödet för att spela avancerade spel på mobiltelefoner växer ständigt och inom några år bör hårdvaran vara ungefär densamma som på PC.

This thesis has been done in order to ease the process of drawing schematics ofelectrical wiring. The need arose after demand from the government due to a seriesof incidents that took place during the revision of the nuclear power plant in year2009.The task of the project has been to create a computer program that can generate agraphical representation of the electrical components relations. The basis for theprogram has been an example of how the client wants the graphical representation tolook. During the course of the project weekly meetings have occured in which theclient has reviewed the work.The result of the project is a program written in Visual Basic Applications that can berun in Microsoft Excel. The program is capable of generating graphics for a majority ofthe cases.

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.

The existence of social networks on the Internet is today seen as broad, and the number of users of the network is increasing. There seems to be many reasons to which people are using the social networks. Within the network, users can for various reasons create groups with different objectives. One of the reasons is that groups are created in order to influence a company. With a perceived feeling that companies handle the problem differently, we assume the source is the uncertainty about what the groups really are.

The purpose of this project was to investigate whether it was possible to develop a type of application, where users would solve chess problems. The main goal of the project was that there would exist an functional application after the study has ended with which users could solve chess problems on a computer. One subgoal of the project was to create corresponding application for mobile phones. The study was limited to require users to have at least Internet Explorer 9 +. For other browsers, there were no corresponding limitations.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
