Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.

The aim of this Masters thesis is to examine what part and importance electronic games play in the life of girls, how the girls use electronic games and what the girls think and say about their use of electronic games. We also intend to examine what girls have to say about electronic games at the public library. Our attempt is to illuminate and bring knowledge to those who work within the library with the selection, purchase and conveyance of electronic games. Method used in the survey is focusgroup-interviews with girls in the age between 12-14 years in three different schools. The findings are related to four different perspectives, theory of child development, from a gender perspective, theories of understanding how young people use computer games and theories to understand the purpose of public libraries.

När man utvecklar en ny produkt eller tjänst står man ofta inför valet av dataformat. De mest använda idag är JSON och XML. Formaten ser väldigt olika ut, erbjuder olika funktioner, men används inte sällan till samma sak. Vilket som egentligen är snabbast finns det mycket åsikter om, men inte lika mycket testresultat. Den luckan skall detta arbete täcka. Programmeringsspråken som används är Python och JavaScript, vilka båda är populära på webben. Genom experiment testas hur snabbt JSON och XML kan kodas och avkodas.

To find useful methods of reading instructions for pupils with Cerebral palsy is a complex but at the same time very challenging work. The main focus of this research lies in studying the pupils work focusing on special adaptation of educational materials and means of assistance for pupils with Cerebral palsy. In trying to get a complete picture of the work with the reading instruction I don?t think that it can be described only by studying the work, it also demands an inside look at the job the working group performs. My overarching purpose of this research is to try out measures to further develop the work with reading instruction for pupils with Cerebral palsy.

How do we perceive literature? In our times computer games and Internet have made us grow more comfortable to the usage of non linear storylines. But how does this apply to printed literature?In this essay, called ?From a to b through d h and o. Non linear storytelling in our time? I have focused on nonlinear literature from different time periods and I have studied novels such as James Joyce?s Ulysses as well as works by William S.

The aim of this qualitative study is to examine how users of talking books perceive the possibility of downloading talking books from home without visiting the library and how this affects them. Three research questions were formulated:How do talking book users reflect on their library usage?Have the subject's' library usage changed since introduction to the download service?How have users experienced the service?To answer these questions, five semi structured interviews were conducted with five different users of talking books in Sweden. All subjects were currently using download services which they had gained access to from their local public libraries. In analyzing the interviews, a theory established by Henrik Jochumsen and Casper Hvenegaard Rasmussen in Gør biblioteket en forskel (2000) was used.

Syftet med detta examensarbete är att utveckla en datorlaboration baserat på aktiv ljudreglering för kursen reglerteknik allmän kurs för maskin och farkostteknik vid Kungliga Tekniska Högskolan KTH. Arbetet ska innefatta en utveckling av en matematisk modell av rörsystemet som ska regleras med en lead-lag regulator. Rörsystemet vid Marcus Wallenberg Laboratoriet ska användas som modellsystem, och den matematiska modellen ska baseras på mätningar insamlade på detta system.Den matematiska modellen skapades med hjälp av ett s.k. identifieringsexperiment och identifieringen baserades på en viktad minsta kvadratanpassning av insamlade frekvensdata. Modellen anpassades till en överföringsfunktion som visade sig ha ett nollställe i komplexa högra halvplanet, vilket motsvarar en svår bandbreddsbegränsning för den aktiva ljuddämpningen.

Vår kandidatarbetstid har resulterat i nio stycken småfilmer som är till för att ge mer information om BTH och regionen för nyfikna. Fyra av dessa filmer innerhåller lite mer information om region, boende/kommunikationer, skolan och det studiesociala. Syftet med dessa fyra filmer är att blanda in BTH på olika sätt, att man sätter skolan som en röd tråd även i region och bostadsfrågorna. Vi gjorde även fyra stycken studentintervjuer, för att visa vad nuvarande studenter tycker om bostadsmöjligheterna och det studiesociala mm. Vi ville även visa att det finns folk från Kiruna i norr till Lund i Söder, som går på skolan, och att det finns många olika typer av människor som du får möjlighet att lära känna om du börjar studera här.

Many companies do not register all the stops that occur in a production plant, it often takes longer to report than to fix the problem. If no problems are registered, you cannot trace where the problems arise.This master thesis was performed at AcobiaFLUX and they have noticed an increased demand from their customers to trace problems raised in their processes. The aim of the thesis was to find out how a tool to monitor a process best could be developed. Then the most essential from the theoretical base was developed into a useful tool for operators. For the operators to know if the process utilizes the full capacity of a process, the tool presents a measure of the Overall Equipment Efficiency, OEE.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

The amount of web APIs that are open to the public is increasing fast. Both the free web APIs as well as the ones that cost money to access. Both bigger and smaller organizations, professional and non-professional developers use these web APIs to add value to their systems or use it to create new applications. This is an area study where alot of research has been done in the last few years. In spite of this there are still no user-centered evaluation methods for web APIs.

System Andersson AB is a company located in Jönköping that works with developing computer systems for the mechanical engineering industry. As of today, when this report is written, the company is working on the development of a new Manufacturing Planning and Control (MPC) system. This new system aims to create not only a user friendly interface but also a modern, stylish interface. To achieve this, the company has decided to work with a, for them, new application framework; Windows Presentation Foundation (WPF).System Andersson is well known for developing systems for different kinds of touch screens, this project is no exception.

The Internet has played an important role for libraries giving them a means of fulfilling their democratic mission of giving equal access to everyone, including people with disabilities. In order to achieve this it is of the utmost importance that they ensure that their web sites are accessible. In this masters thesis we have examined to what extent the web sites are accessible. The thesis is based on theories of human-computer interaction, information architecture, pedagogy and a checklist. The checklist is derived from established international guidelines from W3C, which has been adapted to, and is used by Swedish public authorities to achieve the mission of a ?24-hour authority?.

 This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.

Denna studie har haft som syfte att synliggöra i vilka situationer förskolepedagoger och barn på en förskolas småbarnsavdelning använder sig av surfplattor. Faktorer som undersökts har varit vilka kontexter som utgör dessa situationer, vilka beståndsdelar dessa kontexter består av samt vilka motiv och aktiviteter som ligger till grund för användning av surfplattor. Studien har varit av kvalitativ karaktär och har undersökt en småbarnsavdelning med barn upp till tre år på en förskola i Stockholm. För att åstadkomma detta har semi-deltagande observationer skett på förskolan under fyra dagar. Den insamlade datan har ställts mot och analyserats efter Nardi, Dourish och Benyons teorier om kontext samt Blomberg, Burrell & Guests teori om etnografi.
