Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements.

The purpose of this study was to evaluate Komm-A, a model for usingcommunication books in clinical practice for people with aphasia. The studyconsisted of two group studies and one case study. One of the group studies had apretest-posttest design and consisted of nine couples; a person with aphasia andhis/her communication partner. The material used was Quality of communicationlife scale (QCL), Communicative effectiveness index (CETI), Goal attainmentscaling (GAS), and a questionnaire to the communication partner. The other groupstudy consisted of seven speech-language pathologists who worked with thecouples according to the Komm-A model.

Three years after the Bosman case, it was decided that a socio-cultural approach on sports be introduced in Europe. EU presented a formulation for the same purpose ? The European Model of Sport. The purpose of this formula was to maintain the socio-culture and traditional ap¬proach to all kinds of amateur and professional sports in Europe. If we were to com¬pare this model with the American model of sport, it shows many different ways of thinking in terms of organised sport.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

There is an ongoing evolution in scholarly communication. The traditional way of communicating scholarly results through scientific journals is beginning to be replaced by other means of dissemination. One new channel for scholars to communicate their results is digital publication in so-called open archives. An open archive is a kind of full text database, where a scholar may archive/publish his or her articles, as a complement or a substitute to publishing in scientific journals. There are discipline-oriented archives and institutional archives.

This study concerns digital stories told by five young Romani students and one teacher from Roma Culture Class in Stockholm, Sweden. The theoretical framework draws from theories concerning identity, culture,Romanipe, the Romani value system and social semiotics. The material for the study is the digital stories that were analyzed qualitatively. The results show that the young Roma in the study demonstrate pride in their Romani background and culture, but also signs of changes and development in their culture. Some of the participants do not show external signs of Romani traditions, for example in the ways of dressing.

The intention of this essay has been to investigate how the new digital technology has affected the tourism industry and marketing, as well as how travel agents and tour operators adapt to this. We also aimed to get a broader view of how the future might look like when it comes to marketing and virtual service landscapes. We decided to base our research according to these following four questions:? What affect travel agents? way of adoption to the technical development?? What purposes do the travel agents have for building up their virtual service landscape?? How much does the travel agents emphasize on digital marketing?? What can travel agents do to better adapt to the technological development in the future?We have chosen to use a qualitative research for this essay. The reason for choosing a qualitative research was to gain a wider understanding that would represent a big part of the changes of technology development.

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

Syftet med denna uppsats är att undersöka hur lärare förhåller sig till digitala texter och digitala verktyg. Litteraturgenomgången består av forskning som berör digitala texter, digitala verktyg, mediers betydelse för barns lärande och hur lärare förhåller sig till dessa. En teoretisk utgångspunkt är det sociokulturella perspektivet på lärande med centrala begrepp som literacypraktiker, multimodalitet, medieekologi och progressivism. Vår undersökning bygger på kvalitativa intervjuer med åtta lärare och hur de förhåller sig till digitala texter och digitala verktyg, utifrån frågor som berör arbetssätt, möjligheter/hinder och påverkan från skolans styrdokument. I resultatet synliggörs fem olika förhållningssätt till digitala texter och digitala verktyg; digitala texter och digitala verktyg skapar både möjligheter och hinder, digitala texter och digitala verktyg ger stöd, digitala texter och digitala verktyg öppnar fönster till elevers fritidsvärldar, traditionella skriv- och läspraktiker som normerande syn på digitala texter och digitala verktyg samt Lgr 11 har inte förändrat något.

Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.

This essay examines the narrative aspect of interactive fiction. The study uses Janet H. Murrays analysis of the digital environment and the properties of it as procedural, participatory, spatial and encyclopedic. From this, her three characteristic pleasures in digital narratives - immersion, agency and transformation - are examined from the perspective of interactive fiction. The study also examines Nick Montforts analysis of interactive fiction as a potential narrative and a simulated world or environment.
