Denna rapport behandlar den marknadsinriktade Requirements Engineering (RE) processen. Allt fler företag väljer idag att implementera standardsystem i sina verksamheter. Den situation som ett standardsystem utvecklas i är annorlunda jämfört med den som ett kundspecifikt system utvecklas i. Detta innebär att den traditionella RE-processen inte är anpassad till dessa nya förhållanden.Syftet med denna rapport är därför att utreda vad som kännetecknar en marknadsinriktad RE-process som stödjer kravhanteringsarbetet vid utvecklingen av ett standardsystem. Rapporten avser även att undersöka hur RE tillämpas av marknadsinriktade systemtillverkare i praktiken.

This report presents a study of the basic criteria for computer programmes that may be consideredadequate for aiding children with autism in their education and upbringing. I have based thisstudy on descriptions, opinions and proposals from people who deal with treatment and/orother issues concerning children with autism, as well as relevant literature.The study has been carried out in a major Swedish metropolitan municipality. The intervieweeswere civil servants from this municipality and representing different institutional endeavourson the issue of autism.I used a combination of both quantitative and qualitative techniques, as there was need for bothstandardization and qualitative variation. The main aim of the study was to seek suggestionson how computer programmes should be. That is, if they are to be considered appropriate föraiding children with autism develop their personality.The general conclusion of this study is that computer programmes, that may be consideredappropriate for the above mentioned purpose, should have certain characteristics of whichpedagogic usefulness and user suitability are of primary importance..

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user. A new function to keep track of vehicles outside the main working area at the same time as you still can keep track of the other vehicles in the field..

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

In recent years, agile software development methods have become increasingly popular throughout the world. Today there are a number of different agile methods and they all rest on the Agile Manifesto that was formulated in 2001 as a reaction to the traditional software processes.The aim of this thesis is to make a survey of some of the agile methods used today and to see how they are being used in practice. It consists of two parts: a literature study and an interview study with people working in the software business. First, a definition of agile methods is proposed and a number of different agile methods are described. Second, the interviews are being analysed with special focus on communication, collaboration, expectations and results.

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them.

Portable IT devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these devices are for use by elderly people. This study focuses on the cognitive aspects of the devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.

When performing a QRA you have to consider a number of accident scenarios. How many scenarios you choose often determines the time and resources needed to perform the QRA. The report investigates the possibility that a QRA can be performed using only a few representative scenarios. Further it presents a discussion on how these scenarios should be constructed..

This report is about a thesis that is performed in and for SYSteam Engineering AB in Motala. The thesis work is divided into three parts, study of the market, programming and electronics. The study part consists of examining and comparing different data acquisition systems for testing of different circuit boards, taking into account the modularity, real-time applications, mobility, environmental, interface hardware and software, to be able to define a general module-based data acquisition system in both hardware and software that enables for future developments.The programming part consists of getting started with Visual Studio, which integrates the Measurement Studio for C#. NET. Measurement Studio includes classes and user controls for testing and measuring and offers tools for acquisition, analysis and presentation of real world data.

The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

Denna uppsats beskriver Internet i Kina i allmänhet, från dess politiska bakgrundsmotiv och inledande grunder till dess nuvarande tillstånd av dynamisk ekonomisk infrastruktur och medel för folkligt politiskt inflytande. Tonvikten läggs vid för Kina unika aspekter, såsom partiinflytande över informationsutbytet, folkliga attityder till fildelning i ett samhälle som bara nyligen erkänt privat ägande samt effekter av kulturkrockar på nätet mellan västlig och kinesisk civilisation. Det argumenteras för att Kina i en framtid kommer att ha ett stort inflytande över cybermarknader och i beslutsfattande om Internets framtida utveckling, genom tekniska, ekonomiska och politiska medel. Slutligen resoneras att Internet i Kina har förändrat och kommer att förändra folkets mentalitet, så att det anammar västerländska tankemönster i liknande utsträckning som i angränsande länder, vilket banar väg för politisk pluralism..

AbstractThe ability to read and write is a very important skill in today?s information based society. Most of us learn how to read and write, but not everyone is blessed to do this without struggle. Dyslexia is a very common learning disability and therefore I found it interesting to study how teachers teach students with dyslexia.By studying the literature and by interviewing teachers, I found that dyslexia is a very complex disability. The teachers have to adapt their way of teaching in a way that a student with dyslexia can participate.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.
