There is little doubt that the digital technology has played a major role in reshaping the ways in which we experience the world. In a few decades the Internet has become a vast repository for knowledge and ideas. New arenas where people may meet and fraternize have emerged, and with the help of various digital tools and websites, the production of new material has increased to an almost unfathomable level.But all is not well on the digital front. As the Internet has become a crucial part of our everyday life, certain skills in handling digital media has become very important to master. A well-developed ability to navigate through this ocean of information is needed, and knowledge in managing the risky nature of the internet is critical.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.

Differences between groups or individuals in a society with regards to access to information and communication technologies (ICTs) are known as the digital divide. The digital divide pertains to differences in physical access to computers and the Internet as well as knowledgein using technology. Important factors affecting the digital divide are disabilities, age, gender, socioeconomical background, ethnicity and geography. The digital divide appears on several levels: internationally, nationally, regionally and locally. Individuals who, for some reason, have limited or no access to information and communication technologies risk, among other things, to experience social exclusion.

This exploratory thesis uses qualitative research to investigate how digital music is beeing packaged. The main study consists of 11 deep interviews with key representatives of the digital music industry in Sweden. These are (record companies) EMI, SonyBMG, Universal, Warner, (DSP) InProdicon, (mobile operators) 3, TeliaSonera and (cell phone producer) SonyEricsson. Packaging is a concept of marketing that has specific implications depending on which good or service that is being packaged. Packaging occurs at different levels in the production chain.

In the wake of the electronic revolution digital library has become one of the central themes concerning libraries. The present study takes up the question whether digital library can function in the same way as the conventional library. The question can obviously be posed from different perspectives, e.g. technological-, the user-, or the organizational perspective. The study investigates if (and how) digital library can have the same functions as the traditional library.

Med mitt arbete vill jag undersöka hur man arbetar med portfoliometodiken i textilslöjden och hur arbetet med portfolio kan underlätta för läraren att arbeta utifrån de direktiv som finns i kursplanen för slöjd. Undersökningen har genomförts i enkätform där textillärare som arbetar med portfoliometodiken har fått svara på ett antal frågor med olika svarsalternativ. I undersökningen har det framkommit att när man arbetar med portfolio i textilslöjden så sparas alla elevens arbeten. Den färdiga produkten har fotograferats och sparats tillsammans med elevens utvärdering och i de flesta fall även med lärarens kommentar. Däremot är det ingen som sparar någon bild på produkten under arbetets gång. Trots att fokus har flyttats från produkt till process i Lpo 94. Nästan samtliga lärare tycker sig se att portfolion hjälper eleven att se sin egen utveckling i slöjd, att den hjälper eleven att ta ansvar för sitt arbete samt att det är lättare att motivera eleven att skriva en utvärdering.

BakgrundPortfolio används för att synliggöra barns lärande och utveckling för barn, förskollärare och föräldrar. Portfolion är ett hjälpmedel för att kunna följa barns lärandeprocess. Genom samspel med förskolläraren kan barnet genom reflektioner kring portfolion få syn på sitt eget lärande och sin egen utveckling. Samspelet mellan barn och vuxen samt mellan barn och barn ligger till grund för att lärande ska ske. I bakgrunden har de didaktiska frågorna vad, hur och varför samt hur portfolion kom till Sverige bearbetats.

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.

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

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..

Portfolio är ett bra verktyg för att dokumentera och synliggöra lärandet. Det har forskats om portfolio ur lärarperspektivet men mindre utifrån elevernas perspektiv. Syftet är att eleverna ska se sin kunskapsutveckling och sitt eget lärande under hela skolgången. Det är inte dokumentationen i sig som är det viktiga utan de reflektioner den ger upphov till. Utgångspunkten är elevernas egna satta mål.

This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.
