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.

Den här studien syftar till ett belysa och problematisera kring antropologins närmande av det militära sammanhanget. 2007 utformade USA:s armé en plattform som skulle koordinera och hantera civil kompetens inom områdena antropologi och statsvetenskap. Ämnen som på olika sätt analyserar den ?mänskliga terrängen?. Konceptet ?Human Terrain System? lanserades där akademiker från samhällsvetenskaperna fick söka sig till den militära kontexten för att hjälpa militära beslutsfattare att förstå kulturen, de socioekonomiska förhållandena och religionens roll mm.Hur förhåller sig antropologer till Human Terrain System? Vilka perspektiv finns på antropologin som en del i en militär kontext? Genom att svara på dessa frågeställningar belyses olika resonemang på den tillämpbara antropologin i en militär kontext utifrån den rådande etiska debatten som återfinns inom disciplinen.Implementerandet av antropologiska kunskaper i en den militära kontexten har föranlett till en debatt inom den antropologiska disciplinen.

Computers together with Internet have been growing enormously, during the last decade and the area of information technology has been growing in the same speed. As long as the surrounding environment evolves, the business models must within the IT-area, keep the same pace. So, how do business corporations handle this change to attract customers? How do the dominant business models look like? In many cases, they are apparently much the same. But what differences can we see and what areas can be improved? We have showed that the IT area isn?t just one, it consist of several segments.

Den här studien undersöker hur förutsättningar för lärande förändras genom digital humanities.Utgångspunkt för lärande hämtas ur designteoretiskt multimodalt perspektiv. Teoretiskutgångspunkt för att uppnå förståelse inom digital humanities är hermeneutisk teori. Studien hargenomförts med den öppna metoden litteraturanalys och analyserar antologin DigitalHumanities Pedagogy: Principles, Practices, Politics. Studien belyser digital humanities utifrånolika kunskapsskapande aktiviteter inom lärande och hur lärande kan främjas genom digitalaverktyg och inlärningsmiljöer. Studien belyser exempel på hur digital humanities ställer nyakrav på undervisning och den lärande samt att digitala öppna universitet med fri tillgång tillmaterial och undervisning, förändrar förutsättningarna för institutioner..

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

This study aims to research how digital media can be used for communication and information management between teachers at preschools and children?s homes. To get an understanding of this we have investigated which channels are being used and for what purposes. The interest has also been to explore preschool teachers and caregivers? attitudes towards digital communication in preschools.A qualitative case study of comparative nature has been conducted, where two preschools were selected because of their use and non-use of digital media for communication with caregivers.

In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

The use of digital technology in preschool has been a question aboutif it will be used. By the new curriculum for preschool, it now is a question about how it will be used. My experience shows that many pedagogues are still afraid that the children will miss the interaction whit other children when they are using digital technology.The aim of the study is to see if it is social for the children to use digital technology in preschool.This study is made by inquiry, qualitative interviews and observations.My result shows that children are social active with each other while using digital technology. Turn taking and time determines who will play and what the conditions are. The thesis concludes that children perform social interaction when using digital technology.

Digitala kompetensportföljer ökar i popularitet och deras användningsområde har under de senaste åren ökat. En digital kompetensportfölj kan demonstrera en individs framsteg, prestationer och hjälpa till att visa upp hur väl en student behärskar den kompetensen som krävs inom ett visst yrkesområde. Forskning pekar på att designkompetens och designförmåga är någonting som är svårt att fånga samt förmedla då en stor del av en designers designprocess genomförs inne i huvudet på designern. Jag har genom en kvalitativ studie, intervjuat olika roller gällande deras tankar om hur designkompetens kan utvecklas och synliggöras. Studien resulterade i riktlinjer hur en digital kompetensportfolio kan stödja utveckling och synliggörande av designkompetens..

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Earlier research has shown that combining education with entertainment can improve students motivation in school. With this study we aim to learn more about interactive digital learning resources and how they should be designed to entertain and thereby contribute to motivation. We have identified aspects of educational games that also could be considered when developing interactive digital learning resources, to make them more entertaining and motivating. We have chosen to study and evaluate an interactive digital learning resource called ?Grasp the Disaster?, a fictional online adventure created for students in the ages between 13-15.

The art of producing films have been around for more than a century and the technology just continues to evolve. But although much has happened in 100 years, there are also processes, theories and practices that look the same now as then. I write this thesis because I want to find the differences between the analogue and the digital way of production. This study is based on a qualitative approach because my ambition is to seek the views concerning film production processes. The advantages of analogue film is that it contains more information than the digital formats and that it has a more cinematic style.

In 2005 Gunhild Eriksdotter published Behind The Facades in which she analyses the ways of approaching historical buildings in archaeology. Eriksdotter emphasizes that the archaeology of buildings is in dire need of renewal videlicet the traditional outlook on buildings as two-dimensional objects need to change. She develops a method of analysing the spatial dimensions in a three-dimensional world. By fusing theories and methods in excavating archaeology and architecture, she is able to give us a new way of approaching buildings. Her method includes the analysing of a buildings material, spatiality and use.

The purpose of this study is to examine if digital public libraries are serendipitous environments. Serendipity in this instance is defined as finding something unexpected and valuable, while searching for something else.A survey was conducted at two Swedish digital public libraries, where the patrons were asked to fill in a questionnaire online. The questions were based on the work on serendipitous digital environments by Lori McCay-Peet, as well as considerations of human factors that could possibly influence serendipity.The result indicate that a majority of patrons experience serendipity at the digital library, although it?s still more common to do so at the physical library or on other web sites. The result also confirms the importance of taking human factors into account when studying serendipity.

The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.
