Hur upplever gymnasieelever sin informationssökning? En studie på en skola utan tillgång till skolbibliotek
This masters thesis aims to investigate how upper secondary school pupils experience their information seeking in a school context without access to a school library. It is the pupils own thoughts and opinions about information seeking and criticism of the sources that is the main focus. The literature that has been used consists of material from research concerning youth and different aspects of information seeking such as the information seeking process, information seeking on the web, criticism of the sources and how pupils interact with other people in order to acquire information. The method that has been used is group interviews. Twelve pupils from an independent school without access to a school library have been interviewed in groups of three.

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.

Den militära nyttan med geografiska informationssystem kopplat till eldlednings- och observationsinstrumentet vid precisionsbekämpning.
I takt med Försvarsmaktens ökade engagemang internationellt och det faktum att alla insatsförband inom Försvarsmakten ska kunna verka på alla konfliktnivåer och i en urban miljö kommer nya krav och behov på bekämpningsförmågan att uppstå avseende precisionsbekämpning.Med hjälp av ett GIS kopplat till EOI:et vid en insats i en urban miljö kan en rad vinster erhållas för att stödja artilleriet vad avser precisionsbekämpning. Exempel på sådana områden är: målverifiering, justering av målkoordinater, lägesuppfattning avseende målets närmiljö, redovisning och presentation av verkansområde inför en insats för dimensionering av verkan..
Hello Skandia: Om kulturen på intranätet
Corporate spending on Information Technology is persistently increasing and a majority of companies are currently employing an intranet. Intranets have implications for internal communication but are also instruments for the dissemination of corporate culture. Existing research on intranets and corporate culture is limited to Swedish organizations within the industrial or IT-sector and to foreign companies. The purpose of this study is to understand how or if corporate culture can be embedded into an intranet. Specifically, this study addresses the research question: How is corporate culture communicated via an intranet in a Swedish service-sector company? We perform a qualitative case study and find that communication on intranets is still characterized by a traditional top down approach.
Det är dit man går om man ska söka information. Skolbibliotekets roll i gymnasieelevers informationssökning
The aim of this thesis is to examine how high school students use their school library for their information-seeking. The theoretical framework is based on Louise Limbergs three categories of students views on information-seeking and Andrew Large and Jamshid Beheshtis three categories of students choice of information systems. Qualitative interviews were used and seven high school students were interviewed. The empirical material was compared and divided into 9 categories. The results show that the students see the school library as a place where they can search for information, but its also considered to be a good place to hang out between lessons to study or to meet friends.
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.
Mental arbetsbelastning : jämförelse av flygning under enmotorskedet med flygning under tvåmotorskedet
Som grund för denna uppsats ligger en tidigare undersökning med titeln Undersökning av mental arbetsbelastning under instrumentflygövningar (Andreas Johnsson, 2004). Denna uppsats utgör en fortsättning på ovan nämnda undersökning. Liksom i Johnssons (2004) undersökning har en subjektiv mätmetod baserad på en niogradig skala använts för att utvärdera svaren på den enkät som använts för att få fram data. I denna uppsats undersöktes samma kurs som i den tidigare undersökningen. Det vill säga studenterna i kurs 03:2 vid Trafikflyghögskolan, Lunds universitet.
Mellan digitalt arkiv och socialt forum - en idéanalys av visionerna bakom biblioteksportalen Europeana
Digitizing and digital libraries create great opportunities toprovide access to cultural heritage globally, but the quicklychanging Information Technology environment also raises manyquestions. The aim of this bachelor thesis is to analyse whatvisions and ideas behind one specific digital library, Europeana,that can be found in documentation related to the project. Whatideas can be identified concerning aspects such as userparticipation, access to information, knowledge andinformation literacy? What is the project?s role in relation toeducation, preservation of cultural heritage and democracy?The method used to answer these research questions is adescriptive idea analysis. The empirical material, consisting ofprimary sources written in relation to the project, has beencategorized within dimensions and analysed according toDouglas Raber?s three public library strategies: social activism,the conservative response and the populist initiative.
IKT i undervisningen : En studie kring innehåll och visioner utifrån ett lärarperspektiv
The concept of IT has developed into ICT (Information- and Communication Technology) over the years. ICT has an increasing impact in society and the Swedish curriculum (Lpo 94) highlights the importance of school to convey lasting knowledge that constitutes the general frame of reference that everyone in society is in need of. The purpose of this study was to find out how teachers perceive and use ICT in secondary school and discover the teachers? vision concerning ICT.The used approach for the study is a qualitative research with a basis of interviews. Four interviews are made with teachers from the early years of secondary school, at two different schools.
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.
