There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

At Flight and Systems test Saab AB, a post-processing software is used to process GPS data. A new software by the name GrafNav has been purchased and the purpose of this master thesis therefore became, partly to make a judgment regarding GrafNav?s ability to estimate position, velocity and accuracy, partly to if needed improve the estimate and finally find one or several methods to estimate the position and velocity accuracy. The judgment of GrafNav was performed partly by a comparison to the former post-processing software (PNAV) and partly by a comparison to the airplane?s inertial navigation system (INS).

The legal situation of companies costs for investing in computer software in an income tax law perspective is described by a tax law guidance that generelly acount these costs according the principles of research and development. If there is any reason to classify the costs differently, it could mean that immediate deduction not will be allowed. For this reason it is important to establish what the legal situation would be in a more nuanced tax law classification. The tax law categories that will be analysed in the thesis are research and development, inventories, intangible assets, stocks and ongoing projects. The purpose of this thesis is mainly to give examples of what such an income tax law classification can look like.While dealing with the problems of classifying the costs some situations of competition will occure.

Today there are a big need for a system that delivers overview of all available units for different municipalities and shipping- and security companies due to the increasing requirements for efficiency. The purpose with this graduation thesis is to find out which systems that is suitable to use while developing cost-effective software for positioning and to produce a prototype for such solution.This assignment has been done at the request of PocketMobile Communications AB. PocketMobile is a company that are specialized on delivering modern mobile software solutions and systems to companies with their own vehicle fleet or mobile workers.This master thesis can be split into two separate parts, the theoretic- and the practical part.The theoretic part includes producing a number of functional requirements in cooperation with PocketMobile and comparing the available systems against the function requirements.The practical part deal with the development of a prototype that demonstrates the software recommended. The development tools that best matched the functionality requirements when the selection was made in May 2007 were Map24 and OpenLayers. The system that was selected to use while developing the prototype was Map24, because this product matches all of the requirements and it is also suited for professional usage regarding support, scalability and reliability.

As changes occur more frequently in IT- and software development, it is important for the companies to meet the demands and needs of its customer. The companies have to be able to adapt themselves continuously in order till fulfill its customers changing needs in an effective way, which results in big changes of the companies? structures. The more traditional way of working is often replaced with more alternative approaches as a response to the reputable deficiencies of its predecessors. As an effect of the rapid change and development some companies now see big potential in switching to more Agile and flexible methods and some companies have no choice but to change their way of working.

This diploma work has been conducted for the consulting company Ramböll inUppsala, Sweden with the purpose to perform a study with the calculation programFEM Design 9.0 made by Strusoft. The aim has been to find out if it is possible to gainadvantage by utilizing more advanced 3D software for design calculations, instead ofthe traditional methods currently used in construction works.The method of approach has been to model an existing warehouse building with theprogram FEM Design, and then compare the results with those attained with FrameAnalysis and hand calculations. These results are then analyzed. An evaluation is maderegarding to what benefits can be achieved using a more advanced 3D-model.The results of the study show that the differences between the methods are not ofany significance with regard to the design of the steel frame. However in morecomplex materials such as reinforced concrete, the differences become more notable.The conclusions drawn by the authors of this study into FEM Design are that theeducation requirements of the program are higher than for simpler programs, whosepurpose are solving predetermined problems.

The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

Studien avser att beskriva om och hur faktorernakärnkompetens, osäkerhet, nyttoaspekter och kontroll/flexibilitet påverkat besluten vid inköp av cloud-tjänsten SaaS. Uppsatsen är en kvalitativ studie som är baserad på semistruktuerade intervjuer med nyckelpersoner på två små IT-företag samt vetenskapliga artiklar och litteratur inom ämnesområdet. Studiens slutsats är att de båda företagen påverkats av några eller alla faktorer vid inköpen av cloud-tjänsten. Faktorn nyttoaspekter påverkade båda företagens inköpsbeslut i hög grad. Faktorerna osäkerhet och kontroll/flexibilitet påverkade inte alls inköpsbeslutet hos det ena företaget medan de till stor del påverkade inköpsbeslutet hos det andra företaget. Faktorn kärnverksamhet påverkade det ena företagets inköpsbeslut till en viss del och det andra företaget till en stor del..

Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.

Med denna uppsats vill vi ge läsaren en uppfattning om vad Free Software och OpenSource (FOSS) handlar om och mer specifikt analyseras huruvida FOSS kan fungera ien kapitalistisk värld eller inte. Den grundläggande idén med Free Software ochOpen Source, eller fri programvara och öppen källkod, är att ge varje användare avett datorprogram rätten att fritt köra, undersöka, ändra och vidaredistribueraprogrammet.Författarna ställer i uppsatsen frågan ?Hur kan pengar tjänas på FOSS?. Uppsatsensyftar till att försöka bena ut denna frågeställning. Frågeställningen ger upphov till tvåperspektiv; dels i meningen ?på vilka sätt kan man tjäna pengar på FOSS? och dels ibetydelsen ?hur kommer det sig att det går att tjäna pengar på FOSS då det är gratis?.Uppsatsen knyter an till litteratur kring FOSS samt ekonomisk teori och är främstteoretisk till sin natur.I uppsatsen visas att gamla beprövade affärsmodeller inte kan användas rakt av förföretag som använder eller utvecklar produkter baserade på Open Source.

Syftet med studien är att undersöka vilken affärsmodell som born globals använder vid internationalisering och vilka faktorer som påverkar valet av modell. Studien har använt sig av en kvalitativ forskningsmetod och har genomförts som en fallstudie. Vidare utgörs studien av semistrukturerade intervjuer. Studien kommer fram till att born globals vid internationalisering har en affärsmodell som a?r freemium och att det resursbaserade synsättet samt bransch är viktiga bakomliggande faktorer till valet av affärsmodell. Faktorerna globalisering och entrepenören har mindre direkt påverkan medan nätverk endast har en begränsad påverkan i valet av affärsmodell för born globals vid internationalisering. .

CML Data AB is a small IT-company that offers complete IT-solutions adjusted to the needs of the customers. It is hard for the employees to bring all necessary papers, files and software when visiting a customer. They also have difficulties planning their daily work and to keep track of each other, because of the lack of a shared calendar.The purpose of this report is to answer the following questions:- How do you develop a centralized information system for CML Data AB where it is possible for the employees to gain access to files, plan their days and where the customers can get access to relevant information?- How do you develop an information system that is easy to manage?- How do you make it easier for the employees at CML Data AB to update their homepage?We discussed the problems and the future information system with the employees and were able to establish a set of needs and requirements which we then used as a foundation during the software development. We used user centered system design during the whole process and focused a lot on usability and interaction design.The project resulted in a stylistically pure and user friendly portal.

In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant.
