Syftet med följande arbete är att förstå en grupp lärares och elevers uppfattningar om kunskap samt om undervisningsformer inom ämnet Fotografisk bild. Arbetet ger en inblick i aktuell forskning om lärande i skolan. Med hjälp av en kvalitativ studie inkluderande intervjuer av såväl elever som lärare ville jag förstå deras uppfattningar om kunskap samt om undervisningsformer inom ämnet Fotografisk bild. Det framkom i min undersökning att den digitala tekniken är det som används i samhället idag, och även förändrar vårt sätt att lära och att tolka världen. Den digitala tekniken bör därför vara ett naturligt inslag i elevernas kunskapsbildning. Dessutom kan jag konstatera att den analoga tekniken har visat sig medföra positiva effekter på kreativiteten samt elevernas engagemang.

Att ?sexta? innebär att med textbaserade digitala medier kommunicera med sexuella partners, vilket är en praktik som kan upplevas väldigt intim trots mediets begränsningar av de karaktäristiska dragen av en fysisk interaktion. Denna studie har som syfte att ge en övergripande bild över hur denna typ av interaktion konstrueras och tar sig uttryck, vilket görs i en tredelad undersökning som fokuserar på kommunikationsmönsterna och hur dessa reflekteras över. Det empiriska materialet utgörs av 18 bidrag insamlade via en nätbaserad deltagande observation, 2 kvalitativa intervjuer och 56 svarande på en nätbaserad enkät. Genom ett självselektivt urval avgränsades den studerade gruppen till i huvudsak informanter med en medianålder på 27 år med erfarenheter av heterosexuella relationer.

Social media is by many believed to be the core of a new type of Public Relations. This new PR is called PR 2.0. Most larger companies today are to be find using dif- ferent types of social media to interact with their publics. Each year companies invest more money in this type of digital public relations. Social media is a relatively new online phenomenon and still used at a very early stage.

The digital era has led to technical advances that have transformed the role of the public library from being a place that is used only through physical visits and material, into also being a virtual space that can be accessed by users from outside the library through Internet-based access to e-media such as e-books and streamed or downloadable audiobooks.The aim of this study is to examine how the role of public libraries in Stockholm County has changed in the process of developing into digital libraries: how this has affected their organisation, work methods and strate- gies, as well as their accessibility. The theoretical framework of the study draws on Michael K. Bucklands theory of information accessibility, which is based on six factors of access that are determined by different types of barriers. The methodology is based on a combination of quantitative and qualitative methods. Primary data was gathered through an empirical survey, which consisted of a structured questionnaire distributed to most of the public libraries in Stockholm County and semi-structured interviews with selected librarians and experts for further in-depth understanding.

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.

This thesis explores the position of book blogs in the literary system through Robert Escarpit's socio-literary model of the book market. Simultaneously the thesis serves as a test for Escarpit's theory: by actively applying his theory and model to a very new and contemporary actor on the book market I hoped to reach or confirm new insights into the usefulness and validity of Escarpit's work for contemporary socio-literary studies.Three book blogs were selected for the analysis and interviews were carried out with the authors. The interview questions were formulated specifically for the purpose of extracting the kind of information necessary for an analysis using Escarpit?s theory. As a complement to the interviews, statistics on the type of books reviewed on the blogs were also compiled.

Digital teknik och media har kommit att bli en del av samha?llet vi lever i idag. I Sverige har kommuner gjort stora satsningar na?r det ga?ller digital teknik, dock a?r det fa? skolor som lyckats integrera tekniken med la?randet pa? ett bra sa?tt. Samtidigt a?r den digitala tekniken en stor del av barn och ungdomars vardag.

Syftet med denna uppsats är att diskutera och redogöra för hur religionslärare och läromedelsförlag resonerar kring religionskunskapslärobokens koppling till digital informationsteknik. Genom intervjuer med lärare och läromedelsförlag ville jag ta reda på om det finns en efterfrågan av en lärobok med koppling till digital informationsteknik, vilka funktioner de skulle vilja ha i ett sådant läromedel och vilken funktion det beskrivs få i undervisningen. Resultaten visar att det finns en efterfrågan av läromedel med koppling till digital informationsteknik även om olika grupper av lärare efterfrågar olika saker precis som de förhåller sig olika till teknik och läroboken. Resultaten bekräftar teorin om att ny teknik i skolan leder till en evolution snarare än en revolution då lärarna främst vill kunna använda tekniken till det de redan gör idag. Detta blir en svårighet för förlagen då satsningar på digitala funktioner inte tilltalar den grupp av lärare som använder läroboken mest idag och den grupp av lärare som efterfrågar mer digitala funktioner bara ser läroboken som en i mängden av läromedel och antagligen inte kommer att använda den mer trots nya funktioner..

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed daily. The project is performed at Vattenfall´s district heating power plant in Uppsala. Information is gathered through discussions, drawings of the plant and guided tours of the plant.

The purpose of this essay is to try to understand the relationship between the structures of modern working life and the development of burnout. By using the method of qualitative interviews we wanted to see if the Effort-Reward Imbalance Model could be applied to the data we had collected. Two questions have been highlighted in our research:        ? Is it possible to establish a relationship between the structures of modern working life and the development of burnout among the subjects interviewed?  ? Is it possible to explain the development of burnout among our interviewed subjects through the Effort-Reward Imbalance Model?    Our theoretical frames are the general theories of the modern society and the modern working life as developed by Anthony Giddens, Ulrich Beck and Zygmunt Bauman. We have also used Johannes Siegrist?s medical-sociological Effort-Reward Imbalance Model (ERI-Model).

Jag har i det här arbetet gjort en analys av skillnaden mellan analog och digital summering avljudspår. Analyserna gjordes med avseende på frekvensspektrum, transientrespons och fasdifferens.Det gjordes genom att jag skrev och spelade in två låtar att använda till analyserna, mixade dessaoch körde ut till 24 separata ljudspår per låt. De summerades sedan på tre olika mixerbord och i treolika mjukvaror, för att sedan med Adobe Audition analysera hur frekvensspektrum,transientrespons och fasdifferens ändrats. Därefter gjordes genomsnitt för de analoga och de digitalasummeringarna för att se om det fanns några skillnader dem emellan. Även om det fanns gott omskillnader mellan mixerborden så var fasdifferenser det enda som var genomgående för alla analogasummeringar mot de digitala..

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

The purpose of this report is to create and develop a model that streamlines and helps the innovationprocess of an idea owner and also in the development of ideas.This model should be able to apply for workshops and in innovation advice or business devlopment. I used the qualitative method in my essay just to get a maximum clear data collection, where the seven respondents were included in the interviews. However, much of the information retrieved from the theory books and research/science articles, in order to answer the research/Sceince question in the best possible way.

As a result of a successful human development around the world an extensive urbanization of societies are taking place that are networked in various ways. In these networks, increased travel and digitization are central where individuals and organizations converge in a constant and immediate wireless and mobile technology flow. An example of this is Stockholm and its public transportation company Storstockholms Lokaltrafik (SL). Although most participate in most of the network society, SL is struggling with an audience that seldom travel with them: families with children. We intended to find out how the communication of SL´s digital platforms could get families to travel more with public transportation.
