Design av slutsteg med digital PWM-teknik för gitarr
Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.
Bildernas byggstenar : En studie om pixlar och vektorers egenskaper i form av digitala material
With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.
Unga, nyinflyttade IT-guider : - ett socialt och symboliskt kapital för digital delaktighet
Many reports in recent years are suggesting that young people should be involved in the development of the digital society. The Swedish government's Digidel campaign launched in 2011 involved adolescents to train elderly people. This thesis builds on the campaign with its major aim being to investigate how young people think about digital society and their own knowledge and skills to promote digital inclusion.The research questions were set to examine how adolescents look upon the competencies needed in today's digital society, what specific skills and capital the adolescents suggest that they have which can promote digital inclusion and how projects in this direction are perceived by the participants. The theoretical framework is based on theories about social capital. It encompasses Bourdieu's theories about symbolic capital and people's habitus, Putnam's theories about social capital and the power of the organization and Gidden's vision about how people are organizing themselves in the modern world.

Branding för distansarbetande kreatörer : Förbättra din nätnärvaro
In the fragmented network economy of toady remote work for creative designers becomes mor eand more prevalent. This is good for a number of reasons. Mainly, creative designers can find work inside and outside of their region irrespective of where they choose to live. However, competing for jobs in a global market is harder, and the online presence of the creatives becomes their main shopping window. We have conducted a study, interviewing digital creatives in Västerbotten.
Pedagogers förhållningssätt och barns möjligheter till teknik i förskolan
Syftet med studien är att undersöka vilket förhållningssätt pedagoger har till teknik samt hur deras förhållningssätt påverkar teknik som innehåll i förskolan. Studien är även fokuserad på vad pedagoger ser som hinder respektive möjligheter för att barn ska få uppleva teknik i förskolan.Metoden är kvalitativa intervjuer med 10 pedagoger från 8 olika förskolor.Resultatet visar på en nyfikenhet till ämnet men samtidigt en stor osäkerhet om vad teknik egentligen innebär eftersom teknik inte synliggörs tillräckligt konkret i Lpfö 98 (Skolverket 2006), enligt pedagogerna. Pedagogernas brist på kunskap och intresse ses som det största hindret för att kunna erbjuda teknik i förskolan, men även vilket material som erbjuds och hur det används är ett hinder.I diskussionen uppmärksammas vikten av pedagogens roll som medforskare samt miljöns betydelse för att barn ska kunna utforska sin omvärld..
Klicka här för gemenskap : Hur interaktivitet skapar engagemang och lojalitet
Digital marketing has been changing continuously and rapidly since the introduction of Web2.0 ten years ago (Lin, Li, Deng, & Lee, 2013). Companies are now engaging their users intheir digital marketing by providing with interactive contents in digital campaigns. The digitalcampaigns are getting more converge with SNS (social networking sites) in order to let the usershare the content with others and therefore the e-WOM (electronic word of mouth) helps thecompanies digital campaigns to be shared by more users (Moran, Muzellec, & Nolan, 2014).The interactive content in the digital campaigns have shown to provide for engaged users andtherefore leads to loyal users. The reason for this has its roots in the culture of consumptionthat has brought our everyday consumption to a whole new level where we no longer justconsumes a product, we are the brand (Davis, 2013).The study, Click here for solidarity, aims to explain the interactive phases and rhetorical elementsthat companies use to engage the user to interact with the content of the digital campaigns.The study is based on four digital campaigns in four different market areas in order to providewith an overall picture of how companies work with interactive and rhetorical elements. Thusthe study falls into the area of marketing and branding.
Temarbete inom teknik: en undersökning om elevers intresse
för ämnet teknik ökar när vi arbetar temainriktat i skolan
Syftet med vårt arbete var att undersöka om man kan öka elevers intresse för ämnet teknik då man arbetar temainriktat med VA-system i deras närmiljö. Undersökningen genomfördes med 15 elever i år nio vid Svansteins Centralskola i Övertorneå Kommun under sju veckor tid. Arbetet med eleverna omfattade ett temaarbete, med teoristudier, studiebesök och modellbygge, där de fick undersöka hur VA-systemet var uppbyggt i deras by. De mätmetoder vi använde oss av var enkäter, intervjuer samt observationer. Vår undersökning visar att ett temainriktat arbetssätt inom teknik bidrar till att öka elevers intresse för ämnet teknik..
Instruktionsformer i slöjden
Syftet med denna uppsats är att undersöka vilka instruktionsformer och arbetssätt som fungerar i slöjden. De didaktiska läromedlen i slöjden är få och nästan inga alls och för att studien skulle gå att genomföras tillverkade jag ett eget läromedel med olika instruktionsformer ? digitala filmer, skriftligt och muntligt, i formen av ett gestaltande examensarbete.
Med studien vill jag undersöka instruktionsformernas för- och nackdelar till att vägleda och underlätta elevernas kunskapsinhämtning till ett självständigt elevarbete i slöjden. Lärarens tid i slöjdsalen begränsas av att ge eleverna stöd till att nå kunskapsmålen. Genom att ta in de digitala hjälpmedlen i slöjden i form av datorer, iPads och smartphones förändras slöjdlärarens arbetssätt från instruktör till handledare.
Utveckling och förändring inom digital musikdistribution
Jag har presenterat komponenterna individ, teknik och marknad som utgör musikindustrins grundläggande drivkraft för förändring. I företagsintervjun har jag använt den kvalitativa metoden och diskuterat de individuella processerna, olika tekniker och varierande, ögonblickliga elektroniska marknadsplatser som kan förändra ett köpbeteende. Med historiska perspektiv belyses den nuvarande musikindustrins inkompetens och vidhållande till traditionella verksamhetsmetoder, samt musikbranschens interna oförmåga att modernisera och möta den nya efterfrågan från en musikintresserad allmänhet. Digitaliseringen har medfört en förändrad och utvecklad varudistribution av en elektronisk infrastruktur och nyuppfunna funktioner som verktyg för vardaglig musikavlyssning. Systemutvecklingen på 00-talet har frambringat nya modeller och en tidsenlig användarvänlighet för varje producent och konsument av musik.
Aristoteles och cyberspace : Kunskaper, färdigheter och insikter i hypertextens föränderliga värld
The purpose of this thesis is to deepen the understanding of our contemporary description of digital literacy using the perspective on knowledge from the Nicomachean Ethics by Aristotle. I have chosen to deal with the problem using a hermeneutic approach. The method of inquiry is based on close reading of the selected literature. The selection itself has been made after a strategic selection regarding perspective on knowledge and digital literacy. It appears in the thesis that there are substantial differences but also similarities between our contemporary description of digital literacy from Recommendation of the European Parliament and of the Council of 18 December 2006 on key competences for lifelong learning and the perspective on knowledge from the Nicomachean Ethics by Aristotle.Still, the result has been possible to use for the purpose of the thesis since the problem has an answer and a deepened impression of the understandings of digital literacy..
Lärare och digitala verktyg i matematikundervisningen : En kvantitativ studie om lärares inställning och kompetens kring användningen av digitala verktyg i årskurserna F-3
The purpose of this study is to examine in what extent primary school teachers, teaching children in the age of 6 to 9, choose to use digital tools in their teaching of mathematics. I also want to examine what these teachers think, in terms of advantages and disadvantages, about using digital tools on their mathematics lessons. Finally I want to examine what skills they possess about digital tools.I am using a quantitative method to collect my data. The quantitative survey consisted of a questionnaire survey of ten questions that 38 primary school teachers have answered.The results of my study show that the teachers to some extent use digital tools when they teach mathematics and that the availability of various digital tools are generally good. But it turns out that the availability of tools is not a guarantee that they are used in teaching of mathematics.
DIGITAL VISUALISERINGSTEKNIK : möjligheter, för- och nackdelar
Ever since the development of the pc and their software, in the early 80´s,architects way of work have changed a lot.

Strategiskt arbete med digital tjänsteutveckling : En kvalitativ fallstudie om företags utmaningar och möjligheter
The postindustrial market increasingly demands service infused products to add more value to the customer in order to be competitive. Much research regarding digitalized services indicates that companies have to be innovative in order to compete on the market. However, companies within different industries face different challenges with digital service development. This study has been conducted because there are little known about the opportunities and the challenges different industries faces with a globalized market. Our research question is what the challenges are and what opportunities does strategic digital service development entails for companies.
Digital delaktighet : folkbibliotekens undervisande roll i kampanjen Digidel
In this thesis the pragmatic pedagogy as formulatad by John Dewey is applied to theswedish national campaign Digidel and its work to spread the digital participation among thegeneral public. The purpose of the thesis is to visualize and problematize that differentunderstandings of a problem, lead to different solutions, as lifted in John Dewey´s pedagogy, thatconstitutes the thesis' theoretical framework. The term digital participation is used by the Digidelcampaign, where public libraries take active part to spread digital participation througheducational efforts. By qualitative interviews with four librarians this thesis examines howunderstandings of the term may vary and in turn lead to differenent educational goals, designsand executions. The result shows that basic computer- and Internetskills are seen as either equelto or prerequisites for digital participation and that the digital participant is seen as either apassive recipient or an active participant.
