Detta examensarbete utröner möjligheten att aktivt släcka ut en amplitudstark frekvensmodulerad sinussignal digitalt. Detta skall göras utan förkunskap om signalen gällande fas, frekvens eller amplitud. Eventuellt övriga, men betydligt svagare, sinussignaler i den analoga signalen skall inte påverkas nämnvärt av utsläckningen. För att lösa problemet har olika teorier för att lösa delproblemen med att mäta amplitud, fas och frekvens studerats varefter en lämplig kombination valts för implementering i en FPGA. Prestandan som uppmätts har jämförts med vad som teoretiskt är möjligt och vi konstaterar att metoden löser problemet på ett adekvat sätt men är i behov av en del förbättringar som diskuteras i slutet..

Syftet med denna uppsats är att bidra med ökade kunskaper om och bättre förstå hur fyra lärare använder och förhåller sig till digitala verktyg och digital teknik i undervisningen i svenska för senare år. Studien har en hermeneutisk fenomenologisk ansats och baseras på semistrukturerade kvalitativa intervjuer med informanter som har olika ämneskombinationer. Informanterna i studien har en jämn könsfördelning, är av olika åldrar och har varierande antal tjänsteår. Tematiseringsarbete som mynnade ut i fyra teman kan sägas karaktärisera lärarnas upplevelser av att använda digitala verktyg och digital teknik i undervisningen. Teman som växte fram och även utgör rubriker i resultatavsnittet var den utåtriktade tekniken, den betydelsefulla direktheten, den kontextförstärkande digitala tekniken och den svårkontrollerade användningen.

Syfte Syftet med arbetet a?r att so?ka fo?rsta?else fo?r utvecklingen fra?n traditionell till digitalmarknadsfo?ring samt att analysera hur fo?retag praktiskt arbetar med detta.Studien anva?nder en kvalitativ metod och data har inha?mtats fra?n ba?de prima?ra och sekunda?ra ka?llor.

The purpose of this paper is to analyze and map out the cyber culture of the Internet and its all users, identity, design theories and services. How people communicate and how they build up their identities are some of the baselines. I will also discuss the important aspects of Interaction design and how this can be used in a Community for digital storytelling. The Internet, or new media, was founded in the 60?s by some great philosophers (McLuhan, Rheingold, Lambert and more). With influence from their books I will discuss and analyze what kind of media the Internet is and how it can be seen as extensions to our senses, as McLuhan claims.

The purpose of this master thesis is both to interpret the articles of the UN Convention on the Rights of the Child from a public library point of view and to investigate how childrens librarians in the county of Norrbotten view their working situation in their relation to the users. This purpose leads to the main question: How do the childrens librarians and the childrens library consultant describe the present and the future of the childrens library activities in the sparsely populated regions in the county of Norrbotten? The subquestions are: What articles from the Childrens Rights Convention are the most relevant for the public library? In what way can you notice the Childrens Rights in the way the childrens librarians work towards the users? What part of the childrens library activity is the most important according to the childrens librarians and the childrens library consultant? The thesis is based on qualitative interviews with childrens librarians and the childrens library consultant of Norrbotten and field observations. The result of the study shows that the articles we found most relevant for the public library are 2, 3, 6, 12, 13, 14, 17, 23, 28/29, 30, 31 and 42. The Childrens Rights can be noticed in several ways in the childrens library activities.

The purpose of this thesis was to examine if users of digital music games may acquire skills from the games that may be of use in learning to play a real instrument, that is a non-digitally simulated instrument like an acoustic piano. We have used Gee?s theory regarding a possible interconnection between different semiotic domains, and how this connection may enable a transfer of skills between related domains. In this thesis we examine possible skill transfer between the domains ?digital games? and ?non-digital instruments?. To examine our question formulation we chose to conduct a pilot study from which we collected both quantitative and qualitative data.

The usage of temporary work agencies services is increasing in the Swedish labour market and it has also caused some problems. There have been cases where employers have been accused to circumvent the preferential right to reinstatement by using temporary agency workers rather than rehire preference eligible employees during labour need.The purpose of this thesis is to describe, analyse and enhance the understanding of the preferential rights to reinstatement and study when hiring of temporary agency workers, during the period when there is preference eligible former employees, is permitted. The method being used in this thesis has been applied with particular attention to the directives, laws, legislative history and doctrine.The preferential rights to reinstatement in 25-27 §§ of the Employment Protection Act is a protection which states that the employer has to hire employees or former dismissed employees during increased labour needs. The purpose of this right is that an employer should not be able to terminate an employee due to redundancy and then later hire new employees. An employee is entitled to the preferential right as he/she meets the criteria of the Employment Protection Act.

The purpose of this study is to discuss how journalists think about the interaction with the audience in social media and the fact that it can make the traditional audience feel excluded. The study shows how journalists on P4 Kalmar is experiencing audience interaction in social media and describes how aware the journalists are about the digital divide. The results show that all of our interviewed journalists think that the interaction with the audience through social media works well and that there is awareness among journalists about the digital divide. The results also show that many of the interviewed journalists had not reflected on that parts of the audience can feel excluded by the interaction taking place in social media, but some of them could understand if parts of the audience felt that way. We consider our study as part of a research field on journalist?s interactivity with the audience through different types of media, but also as source of inspiration for future research on how the digital media becomes one with the community..

The purpose of this thesis is to examine if the school's democracy project is successful. The objective is examined in relation to two specific questions. The first question is whether students, after completing their studies in civics A, understand the relationship between the concepts of human rights and democracy. The second is if the students understood the concepts of practical significance and impact on society and the individual. Variation theory comes from the phenomenographic theories and is central to this work. The approach to learning, in this essay, is a change in how a person experiences, understands or perceives a phenomenon. Variation theory focuses on a learning object and contextualization sees as crucial to how the individual perceives the object.The study is based on a quantitative research method in the form of a survey at a secondary school. A number of students may respond to valuation questions about how they perceive democracy and human rights in practical situations. The results are related to curriculum goals.The results of the study is not positive in relation to curriculum objectives, where many students respond negatively to questions..

In this thesis, the four types of math problems that occur in the digital educational math game Zcooly Affären 2 have been analyzed. Focus has been aimed at how the problems mediate instructions and mathematical concepts to players, and how the mathematical content is supported by the context within the game. The result shows both positive and negative aspects of the math problems, based on the theories for math education used in this thesis. Apart from the analysis of the game, this thesis also presents earlier research regarding what possibilities digital games possess as tools for learning. Researchers have partly different views on how digital games should be designed to enhance learning, and whether or not games are efficient to use for learning purposes..

Syftet med examensarbetet är att undersöka erfarenheterna av IKT i Utbildningsvetenskaplig kärna1 (UVK-1) hos lärarstudenterna som läser den nya lärarutbildningen som lanserades 2011. För attuppnå detta syfte ämnar jag att besvara frågan:? I vilken grad har undervisningen i Utbildningsvetenskap-1 (UVK-1) bidragit till att utvecklalärarstudenternas digitala kompetens?Som metod används en hypotetisk deduktiv ansats. Min hypotes är att genomtänkta ochgenomgående inslag av digital kompetens saknas i lärarutbildningen. Hypotesen prövas genom enanalys av resultatet från en enkätundersökning, där lärarstudenterna är informanter.

Högtalare består idag ofta av flera högtalarelement, avsedda för olika frekvensområden. Signalen som driver dessa måste delas upp genom att oönskade frekvenskomponenter filtreras bort ur respektive utgående signal. Normalt görs detta med passiva komponenter i högtalarlådan. I denna rapport beskrivs arbetet med att ta fram ett digitalt system för att ersätta dessa passiva filter. Teoridelen tar metodiskt läsaren till en relevant kravspecifikation för systemet.
