?Vissa kan man lita på mer än andra? . En studie i gymnasieelevers källkritiska bedömningar
The main purpose of this master thesis is to examine how high school students think when they independently are evaluating information for a school assignment. We examine what types of sources they use, and what their reasons are. Besides that we also examine what sorts of criteria they use when evaluating if a source is usable, and if there are any other factors that can have an influence for their choice of material. We have done a qualitative study with 23 students, where the students wrote down their answers in a questionnaire containing wide open questions. We have created our own tool for analysing the material by extracting the most general things in our chapter of earlier research, concerning the three questions which our study is based on.
Computer Network Attack som olovligt våld : en fråga om association, effekt, aktör och mål
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.
IKT och Pedagogik : En kvalitativ studie om datorbaserad undervisning och elevutveckling utifrån språklärares perspektiv
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.

SiLu - Riktlinjer för spelmotor
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.
Är det effektivt? - En studie av ett företag och dess förvaltning av datorbaserade system
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??.
En problemlösningsapplikation för Sveriges schackförbund
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.
Development of Liquid Cooling for PCs
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.

I have also studied their needs for further education and how it can be addressed in social media, in order to learn how a B2B-company that educates in sales training can meet sales people in social media. It?s an empirical study based on individual interviews with a semi-structured interview template. Respondents were of mixed age, both men and women.
Det nya bokförlaget: Att skapa en roll på marknaden
As more and more book publishers are starting up in Sweden, despite of tough competition, this thesis aims to understand the necessary resources required by new publishing houses in order to create a long-term role on the national publishing market. This is a market characterized by a high level of cultural interests, where success is not always measured in economic profit. Four new publishing houses have been chosen, whose start-up phases and entry processes are described in order to determine what factors have been essential in creating a role. In addition, relevant actors such as other publishers, distributors, and retailers have been interviewed with the purpose of acquiring the complete picture of how the new publishers? can create a role within the industry.

Fluidrörelse- och värmetransportsmodellering i götugn
The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.
Stereotyper i den virtuella världen. Hur visuella intryck påverkar deltagares uppfattningar av virtuella agenter
The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..
Intranät En kommunikationskanal för alla?
Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.
