IP-telefoni - En explorativ studie om vad som påverkar konsumenters användande av IP-telefoni

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.

Hållbar energi : - Ett initiativ till utveckling av bränsleceller i Sverige

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.

"De är ett väldigt nyfiket släkte, barnbibliotekarierna". En kvalitativ undersökning av hur 1990-talets samhällsförändringar påverkat barnbibliotekariernas arbetsuppgifter, kvalifikations- och fortbildningsbehov

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.

(O)kritisk informationskompetens? : En utvärdering av undervisning i informationskompetens inom högre utbildning

The purpose of this thesis is to examine the benefit of information literacy instruction in two student groups at Kristianstad University, in relation to development of critical information literacy and within the boundaries of the educational goals. This study takes on a critical information literacy perspective that combines critical pedagogy and standards for information literacy in higher education. Two methods have been used for data collection: interviews and questionnaires. According to the results of the study the information literacy instruction provided by the Kristianstad University Library is important and useful for the students in their academic studies. It also becomes clear that the information literacy differs between the two groups as a consequence of the varying information literacy instruction received by the two groups.

Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology

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.

Wickrpedia : Integrering av sociala tjänster

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.

Kartläggning och analysering av initieringsprocessen : En fallstudie utförd hos Teknikgruppen för RV2012 på Sandvik AB

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.

Kunskapsorganisation av ämnesområdet arktektur : Klassifikation eller indexering av samlingarna på en arkitekthögskola?

Kan Hedvig lösa De mystiska tecknen? : en studie av två biblioteksdataprogram för barn

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..

Värdering av katastrofers miljökonsekvenser

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.

Nostalgiska Ljud

Det finns ljud som är på väg att försvinna i takt med teknologins utveckling. Dagens ungdomar har aldrig hört ljud från den äldre teknologin, som den äldre generationen har fått växa upp med såsom skrivmaskinen, modemet m.m. Dessa produkter gav ifrån sig ett speciellt ljud som numera inte hörs lika mycket idag. Men vad händer när tekniken utvecklas till den grad att ljud blir en säkerhetsfråga? Förutom teknikljud finns det ljud från förhistoriska och nyligen utdöda djur som forskare har lyckats återskapa genom studier av kvarlevornas anatomi.

Teen dating violence : Samverkar våld i relationen depressiva symptom hos ungdomar?

This paper examines dialect as a rhetorical means of persuasion. A survey containing inquires about four different Swedish dialects have been handed out mainly in Södertörn University and Stockholm University, in order to research the values and connotations of theese dialects. The four chosen dialects are as following: Göteborgska, Stockholmska, Norrländska and Skånska. The results of the survey are processed and compiled to see which attitudes these values and connotations may indicate to each dialect. These attitudes and values are then discussed in correlation with five rhetorical theories: Attitude as a means of persuation, Ethos, Persona, Rhetorical Agency and Pierre Bourdieu?s theory of Field and Habitus.

Förändring av intranät och dess inledande utmaningar

Organizations today face changes continuously as the society, the surroundings and the technology change. The information technology used in organizations has become essential, where intranets are a big part of it. Many organizations embrace social intranets, and these kind of changes has an impact on the members in the way they work, handle information and communicate. As many organizations and the members in it face new kinds of changes, they also face new kinds of challenges. This paper presents an interview study at Smurfit Kappa Kraftliner in Piteå, whom are about to go through a change process unlike any other change they have ever gone through before.
