We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

This project report shows the work around a mockup to a three-dimensional avatar-making application. An avatar-making application is a computer-based software program in which it is possible to create your own personal virtual character. The possibility to use three-dimensional avatars can in the future be essential for adding extra personal information or characteristics to social communication over the internet or over mobile phones. The problem of transforming a physical form and reconstruct it to a virtual basis has been an important problem to solve for many companies and software developers in the, for instance, virtual worlds area. Methods and ideas over making this transformation is the key throughout this project.

Heat and power stations are often in need of optimizations. A simulation model is a tool for findingways to optimize the plant.

Among the included parts in the boiler are cyclone, convection part andINTREX-chambers.

The objective of the thesis is primarily to conform and encode a digital signal to be controlled by software. The idea is to transport today?s tracesignal through the IP-network instead of cable-net. In this report I will suggest a possible solution to get a fully passed result with no peculiar time delay. I will also suggest some ideas for a future work with the new tracesystem..

For many companies, the Internet has revolutionized the relationship they have with their customers concerning costumer service. The use of Information Technology in regard to Internet as a media has provided companies with the opportunity to build customer databases in order to target their customers individually. The airline industry was one of the first pioneers to use the full potential of Internet to improve customer relations and its profits which we aim to investigate in greater detail in our thesis.Our thesis answers the question on how Scandinavian Airlines' (SAS) Eurobonus department uses their website to create valuable and profitable relationships with SAS loyalty club members through direct marketing. In order to answer our research question, three key informants have been interviewed - each representing different sub departments at Eurobonus; service and support, IT and marketing. Our results were that the Eurobonus department use direct marketing methods by sending customized e-mail offerings to target specific customer, using their customer databases.

As self-service technologies become more common in service provisions, a deeper understanding is needed of how customer satisfaction is affected by automated service encounters. Drawing from theories of customer satisfaction, human interaction, and the dynamics of complex service provisions, the differences between automated and interpersonal service encounters in the initial part of a service provision are examined in terms of customers? evaluation of the service encounter itself, overall satisfaction, as well as the service encounter?s impact on global evaluations and evaluations of other non-dependant service encounters. The study was performed on people travelling by air on Swedish domestic routes. Passengers were asked to evaluate the airline?s performance on different attributes of the air travel they had undertaken, as well as to form an overall evaluation of the service.

The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

This thesis processes the work of developing CPU code and GPU code for Thomas Kaijsers algorithm for calculating the kantorovich distance and the performance between the two is compared. Initially there is a rundown of the algorithm which calculates the kantorovich distance between two images. Thereafter we go through the CPU implementation followed by GPGPU written in CUDA. Then the results are presented. Lastly, an analysis about the results and a discussion with possible improvements is presented for possible future applications..

This study is aimed to increase the knowledge about the Swedish immigration authorities? assessment of the asylum applications based on particularly distressing circumstances, submitted by disabled undocumented migrants. Making an attempt to explain the reasons of asylum-seekers? health deterioration during the asylum process, this study determines the factors in migration authorities proceedings affecting such deterioration. Documents in five personal files concerning six disabled asylum-seekers, whose applications were declined, were studied by applying two observational methods: content analysis of the documents in the personal files and non-participant observations made during receptions of undocumented migrants at the Swedish Asylum Committee.

Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.

Many workplaces around the world use some kind of presentation software as an aid during presentations. At Westinghouse Fuel Service in Västerås they experienced that they didn´t know how to use this medium to its fullest extent. They wanted to increase awareness of presentation skills with PowerPoint among the employees, to improve their internal and external communication. A desire they are certainly not alone to have in the working life.My research studied how to design guidelines for the use of presentation software, so the users can easily absorb the message and find motivation to use the guidelines. In order to adapt the guidelines to their users, and thus create major opportunities for them to absorb the message, I based my study on the concepts legibility, readability and reading value.

Prioritisation of software requirements is a critical part of the development of software. Whichrequirements and in which order they will be developed is one of the main tasks that requirementprioritisation supports.There are different ways that a requirement prioritisation can be used, for example alone or in agroup and with different methods.The purpose of this report is to map out how you can carry out a requirement prioritisation alonewith different types of prioritisation methods and how you solve the problems that can arise whenprioritisting requirements. This is done by documenting the use of three different types of methodsthat can be execute alone. The methods are "100-dollar test", "Ranking" and "Top-tenrequirements".To be able to prioritise requirements, you need to establish which requirements you shall prioritise.The paper retrieves this information by interviewing stakeholders in the system and analysing theresult of the interviews and the execution of the requirement prioritisation.Three problems arose during that work and I present solutions on these problems. The problemswere 1) equivalent requirements when using the "100-dollar test", 2) low differentiation gradebetween the prioritised requirements in the "100-dollar test" and 3) that the requirements that wereprioritised weren't classified before the prioritisation, which leads to inaccuracies in the resultingprioritisation.The solution to the problems that the paper presents is to increase the amount of distributable unitsin the "100-dollar test" to 1000 per requirement, suggestions of classes of the requirements andthe combination of the methods "100-dollar test" and "ranking" to bypass the equivalentrequirements.The report is written in Swedish.Nyckelord: GoTRIS, requirements retrieval, requirements analysis, Viktoria Swedish ICT,requirements prioritisation, requirements, 100-dollar test, ranking, top 10 requirements..

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

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.
