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 company Microshop is interested in implementing new features in their product-website, and would like to examine the possibility and usefulness of introducing such Functionality. When designing interaction for commercial websites, it is important to make the menus easy to use, and refrain from using deep hierarchies in order to avoid causing unnecessary burden for the users. There is an interest among users for adaptive Functionality, but this requires great amounts of trust in the website from the user. Something which can be created by refraining from using implicit information, and provide detailed explanations throughout the website. A usability test was conducted in order to complement the data gathered from the theoretical study, the interviews and the expert evaluations.

Human-computer interaction is central for computer assisted development. The aim was to investigate the user experience of a new (U2) compared to an old (U1) computer system, within a cognitive psychology frame of reference. Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

Today?s cell phones include more and more Functionality, it is no longer uncommon to be able to connect to the Internet or take photos with the cell phone. In this thesis the question is if the cell phone users are interested in this new Functionality. Are there people who are interested in a cell phone that in this thesis is called ?Basmobilen? (the entry level phone), which include the following functions; phone call, SMS, phone book, calling lists, clock and the possibility to change the call signal.

The consultancy firm Knowit sought a smartphone application for communication between schools and pupils. Together with the students, it was decided to create the app both for Android and for iPhone. The project would produce a prototype app with limited Functionality usable as a proof-of-concept in communication with potential customers.The questions that have characterized the work are; what features would be demanded in a school app, how to program user-friendly Functionality and how to use object-orientation to design such an app. A question has also mentioned the differences between development for iOS and Android. The work was done in an iterative process in which the students worked together with planning, programming and testing.

The .NET Framework is a widely used system component for MicrosoftWindows. This thesis describes how the Functionality of the framework canbe adapted to Microsoft Excel. Specific operations, such as integration ofuser interfaces, database connections and the ability to divide programs intosmaller components, are discussed. A number of architectural - and designpatterns to facilitate development are analysed.Several techniques have been made up in consultation with experiencedprogrammers. These techniques were further developed by implementinga number of test programs.The results of the study are a number of standard classes for future usageand a larger pilot project containing most of the analysed Functionality..

The usage of Unmanned Aerial Vehicles (UAV) for several applications has in-creased during the past years. One of the possible applications are aerial imagecapturing for detection and surveillance purposes. In order to make the captur-ing process more efficient, multiple, cameraequipped UAV:s could fly in a for-mation and as a result cover a larger area. To be able to receive several imagesequences and stitch those together, resulting in a panoramavideo, a softwareapplication has been developed and tested for this purpose.All Functionality are developed in the language C++ by using the software li-brary OpenCV. All implementations of different techniques and methods hasbeen done as generic as possible to be able to add Functionality in the future.Common methods in computervision and object recognition such as SIFT, SURF and RANSAC have been tested..

The initial aim of the roll out of smart electricity meters in Sweden was to allow remote readings of the households? monthly electricity consumption for billing purposes. Since then the transition towards a smart grid has become a more prioritized matter. In the roll out of next generation smart meters more attention is therefore given to how the Distribution System Operator (DSO) can benefit from the meter through different smart grid applications. This study uses a qualitative research method to identify three general fields of application and 15 specific concepts corresponding to ways in which the DSO can create added value from the information provided by the smart meter.

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the Functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed Functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people. I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala. The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value Functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from Functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate. .

EPiServer is a content management system where users can publish information on a website by using a web browser. EPiServer has a built-in search engine that is very simple. Many customers using EPiServer web publishing system is in need of more Functionality than is offered by EPiServer's built-in search engine. The purpose of this thesis is to develop additional Functionality extends that the built-in search engine in EPiServer. The assignment was also to identify what need to be developed in order to give customers a better  opportunity to help their visitors find the right information on their website.Since this thesis was started in 2005, a number of commercial search engine productsentered  the market and it has become more common for companies to invest inthese products instead of using the simple search engine that's built into EPiServer.These products have many of the features that have been developed in this thesis.Another crucial difference between EPiServer?s built in engine and other products isthe method used to index content.

In this thesis we have developed a framework of features associated with eCommerce platforms and then defined them. Thanks to our interviews with eCommerce-developers, we have been able to define multiple eCommerce features with the focus on an owner?s perspective. Much of the previous research in the area, takes a user perspective when the Functionality of eCommerce-platforms have been assessed and evaluated. We have therefore taken an owner?s perspective in the evaluation of eCommerce platforms and therefore produced a suggested framework with key features associated with the owner's functions.

The goal of this thesis is to investigate the W3C Geolocation API from a developer?s perspective, focused on whether it makes development of location-based applications more accessible to developers. This has been investigated by looking at available ways to locate, possible uses, the Functionality offered, the necessary level of prior knowledge needed for a developer and requirements on developer tools. This has been achieved through studies in relevant areas, a thorough introduction to W3C Geolocation API Functionality, and by using the API to develop two different location-based applications as a demonstration. Testing of applications, on different platforms and in different environments, in conjunction with investigation of the rest of the material has shown that W3C Geolocation API in many ways actually makes development of location-based applications more accessible for developers.
