SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.

Background: In recent research literature, some researchers mean that companies in fast changing markets have to act proactively while others find that companies have to adapt to conditions and to react. This makes it interesting to study how software companies act strategically and also to study to what extent a flexible organisation is required by companies who proact and by those who react. Purpose: The purpose of this thesis is the study how different types of software companies act strategically and what this requires of the company in terms of flexibility. Delimitation: The study treats only Swedish software companies with more than ten employees. Proceed of the Study: Representatives from four case companies as well as a consultant have been interviewed.

Microsoft launched a new operating system, Windows 8, during 2012. An interesting feature for Windows 8 is that applications can be developed using different programming languages but still provide the same functionality regardless of the language used. Two combinations of programming languages are: XAML with C# and HTML with JavaScript. This thesis examines if there are any advantages or disadvantages when choosing a specific combination of languages to develop Windows 8 applications with. An application has been developed and analyzed for the SwedishTransport Agency during the thesis project..

An increasing amount of companies and organizations are starting to implement the use of cloud computing in their business. This trend results in that software, which was previously sold and distributed to the customers whom then had to install the software on their own computers, now is being replaced with Software as a Service (SaaS). SaaS makes software available through the customers? browsers, which results in that the service providers only have to administer a single application. The process to migrate a distributed application to a service delivered as a SaaS lacks sufficient investigation; this paper will provide some guidelines for conducting such a pro- cess.

The use of mobile devices has during the last years expanded and on the market you can see a huge amount of applications. The development of mobile applications differs from traditional systems development since mobility infers that mobile applications can be used in different technological and social contexts. Although previous research has recognized that mobility can present mobile application developers with certain challenges, empirical studies of how problems arise and how they can be handled has thus far been limited. In this study we focused on the requirements engineering process from a development view with the purpose of finding challenges emerging in the development process. The study is based on a qualitative case study that employed semi-structured interviews with both project managers and system developers active in the requirements process.

In this paper we analyze a social network specifically designed for the elderly, people with Dementia and people with generally low computer experience. This is a relatively unexplored use for such software, and our goal is to find out whether the technique to be used is simple enough to use for the intended user group, and generally how the whole situation is experienced by the users. To achieve this we conducted an expert evaluation and interviewed a number of users at two separate occasions during their first weeks with Modernfamilies. We came to the conclusion that this software generally is simple enough to use for the intended target group. Some of the users we came in contact with experienced the software as a positive addition to their daily lives, while some could not see any reason for a further use.

The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.

The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.

This thesis investigates how a developer can move a desktop application to the web environment. The investigation also includes finding out what are the limitations of a web application and what is not possible to move to the web from the desktop. The question is whether there is any functionality that is gained or lost in the web application after the move.A survey has been conducted to find out what types of problems occur when moving an application from desktop to the web. The authors of this thesis have developed two prototypes for a company who wants to move a limited part of their current desktop application to the web in the future. The prototypes have been developed in Silverlight and ASP.NET.The survey has revealed that one of the disadvantages of web applications is the difficulty in working with local files and hardware on the computer.

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 aim of this paper is to investigate how well information and communication technology (ICT) is implemented in the new teacher training program in the subject of Swedish and how this is presented in the applications for examination licence to the National Swedish Agency for Higher Education. This is an interesting field of study, since ICT has been selected, by an investigation chosen by the government to be one of four overall perspectives that are supposed to permeate the teacher training program. There have been several difficulties involved in this project of which one has been the extent of the material.  27 applications and all curriculums in the subject of Swedish belonging to them have been examined. Another difficulty was that the applications and the curriculums are written by different persons under different conditions such as time and resources.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

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.

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.
