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.

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..

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality. StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.

Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.

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.

The purpose of this study is to examine what motivates people to help others at risk to themselves. The focus is on international aid workers, which in their work put themselves in situations of risk. Earlier research shows that international aid work involves risks such as infectious diseases, violence, death threats, assaults, constant insecurity and risk to be traumatized etc. There is not much research done on what motivates to help others in spite of risks, hence we find this an interesting area. We have interviewed six respondents about the content and character of their motivation and factors that are important for the maintenance and development of this motivation.

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.

Företaget som studien utförts på upplever ett problem vid hanteringen av underhållsarbete i fabriken. Processerna för felrapportering och beställning av reservdelar är tidskrävande och involverar arbete från flera olika parter. Merparten av allt underhållsarbete som utförs är av oplanerat slag och ett fungerande uppföljningsarbete för att komma till rätta med de pro-duktionsstörningar som äger rum i processen saknas.Syftet med examensarbetet har varit att skapa underlag för att förbättra företagets effektivitet genom att optimera underhållsarbetet med hjälp av förslag till ett underhållssystem och olika tillvägagångssätt för att effektivisera underhållsarbetet.Under arbetets gång har en underhållsloggbok utformats i Excel. Loggboken används till att logga alla underhållsarbeten som inträffar i produktionen. Dessa arbeten ligger till grund för merparten av de beräkningar som utförts under projektet.Beräkningarna syftade till att kartlägga var i processen flest fel inträffar och av vilken karaktär dessa fel är.

This paper describes the process of building a machine translation lexicon for use in the train and transport domain with the machine translation system MATS. The lexicon will consist of a Swedish part, an English part and links between them and is derived from a Tradostranslation memory which is split into a training(90%) part and a testing(10%) part. The task is carried out mainly by using existing word linking software and recycling previous machine translation lexicons from other domains. In order to do this, a method is developed where focus lies on automation by means of both existing and self developed software, in combination with manual interaction. The domain specific lexicon is then extended with a domain neutral core lexicon and a less domain neutral general lexicon.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.
