Despite the fast growing development of IP-telephony services, only a small number of people in Sweden use them. Of the total amount of fixed telephony subscriptions, maximally five percent are based on IP-technology. Through an exploratory study, the main purpose with this thesis is to identify factors that influence the use of IP-telephony on the consumer market, and the factors? internal relationships. The thesis also has two sub-purposes: firstly, chart the supply of IP-telephony services and secondly, discuss what IP-telephony services that are requested by today?s customers in the future.

In the world we live in today the environmental issues has become increasingly important, and we have begun to realize that we can not continue to use fossil fuels at the rate we do. When it comes to generating electricity we are constantly trying to come up with cleaner and more efficient solutions. The fuel celltechnology is one such alternative and has been around for over 100 years. Yet, it is not until now that the world has started to notice this great technology. The fuel cell has been developed in several areas and can today be used for handheld electronics, vehicles and small settlements.

Arbetet grundar sig både i en empirisk och teoretisk studie. Jag har gjort en kvalitativ undersökning, där en observation på tre olika skolor i Västerbotten har lagt en grund för arbetet. Fokus har legat på att studera hur lärare tar tillvara och kopplar undervisningen till elevens tidigare kunskaper, för att få en helhet och förståelse i skolan samt hur moment börjar och avslutar och om det sker någon uppföljning kring momenten. I observationen låg även fokus på hur elevernas färdiga material hanteras och samlas.Syftet är att försöka komma på ett sätt att kunna dra nytta av tidigare kunskaper eleven fått, för att skapa förståelse och ett helhetsperspektiv i skolan. Jag har gjort litteraturstudier hur portfolioteknik fungerar och hur man kan koppla till tidigare kunskaper.

The  change that has occurred during the past few decades concerning the development of electronic records, information technology and the constantly increasing quantity of information, have confronted the archival discipline with new challenges. In the digital world, the concept of ?record? has changed from representing something lasting and physical to something much more abstract and transient. The way to approach archival description has also changed, from focusing on the static preservation of archival records, to documenting the transactions of organisations, and to clarify operational processes. The discussion about the general purpose of the archival discipline, and its place in a changing world, has led to a new approach to archival description.

The purpose of this master thesis is to investigate what the work situation of children's librarians looks like in the year 2000, after the changes in society which took place since the 1980's. Did the tasks of children's librarians change during the nineties, and if so, in what way and why have they changed? Which new knowledge needs emerged for children's librarians during the nineties, and what was the cause of these new needs? Finally I want to know which needs for professional development arose, and how these needs are fulfilled. The thesis is based on qualitative interviews with children's librarians, library managers, library consultants, one representative of the Swedish school of Library and Information Studies and one member of SAB's children and youth committee. The study reveals that the identity of children's librarianship is strongly associated with the stimulation of language and reading.

Den tekniska utvecklingen har lett till ett ökat informationsflöde. Telia är ett företag som de flesta associerar med just kommunikation och flöden av information. Telia kanal Partner är den del av Teliakoncernen som är ansvarig för företagskunder. Volymen post som kommer till kanal Partner och därefter delas ut till medarbetarna har minskat de senaste åren eftersom allt mer av den post som tidigare kom via Posten nu kommer via e-post och andra digitala överföringsverktyg. Kostnaden för att sortera och dela ut posten är densamma vilket har lett till att kostnaden per försändelse ökat.

Bakgrund: Från att ha förmedlats via grottmålningar, papperstidningar, böcker och skivor har distributionen av contentprodukter blivit smidigare i och med att internet har fått genomslagskraft. Denna typ av distribution är mycket snabbare och dessutom i många fall billigare än de tidigare typerna. Dessutom finns det numer möjligheter för gemene man att publicera och distribuera content. Syfte: Att undersöka hur contentdistribution i musikindustrin förändras på grund av den pågående övergången från analog till digital ljudförmedling. Dessutom undersöka vad det finns för incitament till fortsatta förändringar i framtiden.

The tourism industry in Sweden has expanded in recent years and the increasing industry has meant that customers are in need of a reseller for their trips abroad. Today there are three types of retailers available. These are : Traditional travel agencies , tour operators and online travel agencies.Online Travel agencies are the most modern online option for customers. Their existence has made it easier for the customer and reservation can be made anytime and anywhere. The competition has intensified between the three retailers and the traditional alternatives must find new ways to survive.

In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

Our society has become more and more digitalized and we have access to more information than ever before, which has had an effect on both our personal and professional lives. This change has naturally also changed the way in which organizations are structured and how they communicate ? both internally and externally. Intranets, e-mail and other technical channels are an important part of most organizations in-house communication today.The aim of this study is to examine how the internal communication in a medium-sized firm, CranabSlagkraft in the north of Sweden, works. The focus in the study is on the existing intranet, and if there are any differences in the opinions between the firms leaders and the employees that works in the production.

The web has evolved much through the years. From being a place where author and reader were clearly distinguished, it now invites everyone to take part in the development of both content and technology. Social services are central in what is called Web 2.0. Wikis, blogs and folksonomies are all examples of how the users and their communities are key to the development of services. Collaborative writing, tags and API:s are central.

This thesis has been carried out to the Technology Group at industrial plant Tube Mill2012, which belongs to the Sandvik AB. Technology Group is a unit that takes care ofall requirements and suggestions regarding investigations, test runs and designmodifications. The main objective is to identify and analyze the existing initializationprocess to see where improvement opportunities exist and to come up withsuggestions for improvement, supported by previous research and literature. Anextensive literature search and case study has been conducted to provide a solidfoundation to refer to during the work. Completing the interviews and the workshopgave a clear picture of their unstructured work and approach, how the lowrequirements on the received orders caused problems for the group as well as thelack of a standardized resource allocation method provides major delay factors.Solution proposal then became a very easy process model in five steps with all theinformation gathered in one place.

This thesis examines which function the information technology may have in thechildren's library, with the example from two library computer programmes. One is anexpert system, Hedvig, which will help children to choose and to find books, and theother is a computer game, The mysterious signs, that will teach children library user education.The main question is: What conceptions do the project-leaders, the children'slibrarians and the children have concerning the function of these two programmes in thechildren's library?The study is based upon qualitative interviews with two projects-leaders, fourlibrarians, three computer programmers and twenty-eight children.The theoretical material consists of examples on other library computer programmesfor children developed in Denmark and USA, some American studies in children'sabilities to use computerized information retrieval systems, and studies concerningchildren's relations to computers.The adult's conceptions of the computer programmes are divided into categories asfollows: Democracy, aspect of sex, complement, marketing, reading promotion,development of competence, information technology development, pedagogics, adulteducational activities, compensation and armusement, pedagogics, usefulness,effectiveness and information. These categories shall be seen as the conclusions of the thesis..

When a disaster occurs the main focus is on the loss of human lives. Here the environmental effects have been in the centre of attention. This work has had two main purposes. The first one was to formulate attributes, variables that together present a complete picture of the consequences that an event has had on the environment. The other main purpose was to investigate how people value the impact that a disaster can have on the environment.
