1553-Simulator. In-/uppspelning av databusstrafik med hjälp av FPGA
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).
Sju heuristiker för utvärdering av webb-API:er
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.

Om man bygger dörren för liten kommer ingen in: En kvalitativ studie av tillgängligheten på folkbibliotekens webbplatser
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?.
En utvärdering av Peabs inköps- och avropssystem
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.
Svärmen kring pekskärmen : En kvalitativ studie om surfplattan på förskolan
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.

Vilka faktorer bidrar till att spelare fastnar i MMORPG spel?
Massiva onlinerollspel är idag mycket populära och försäljningen och spelandet utav dessa ökar markant. I och med detta väcks frågan om vad det är i dessa onlinespel som gör att människor spelar och fortsätter spela. Denna uppsats inriktas främst mot MMORPG:s, Massively Multiplayer Online Role-Playing Games, då författarna anser att det är i denna onlinespelsgenre den största möjligheten att finna och definiera de faktorer, som påverkarspelares vilja att spela, finns. För att ta reda på dessa faktorer skapades en enkät vars frågor utformades med en gameflowmodell i baktanken. Denna enkät lades sedan ut på sex olika onlinespelsanknutna forum, där totalt 105 spelare anonymt deltog.
Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet
Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.
Fysisk aktivitet på Fritidshemmet : En kvalitativ intervjustudie av fritidspedagogers uppfattning om fysisk aktivitet
The aim of this work is to investigate what after-school teachers from various schools and after-schools feel about the importance of physical activity. But also how they work to stimulate and support children/pupils physical activity development in the after-school center.The work also highlights health from a physical perspective. The study provides a historic look of the conditions for the after-schools. Through qualitative interviews I want to find out how the after-school pedagogue thinks of physical activities importance for the health and development of the children.

Operatörsoberoende SMS-leverans med designmönstret Bridge
When different type of programs are developed one wants to make these
adjustable to future changes and requirements. It must be done a good design of
the program from the beginning to make it possible to continue development of
it without having to redo big parts of it to high costs. In the area of object
orientation there are design pattern, which can be used to design systems that
can be adjusted to new changes in an easier way. I have in this thesis chosen
to take a closer look at how to design a program that sends SMS to cell phones
through a system of an operator. One requirement on the program is that it has
to be possible to change what operator to send though in an easy way.
