The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

The aim of the study is to investigate how a teacher uses multimodal resources with an interactive whiteboard while teaching reading and writing. The aim is also to investigate what view the teacher has on using an interactive whiteboard while teaching reading and writing. Video-recorded observations and audio-recorded interviews are the methods used to collect data. The analysis was performed from a multimodal perspective and is also inspired by interaction analysis. The result of the analysis showed that the teacher uses several multimodal sign systems in combination with those found on the interactive whiteboard.

Undersökningen tar upp hur rösten används, närmare bestämt berättarröstens påverkan, när den tjänstgör som berättarverktyg för läsupplevelsen. Språket är inte bara förknippat med det mänskliga intellektet utan också med den mänskliga kroppen. Språket är bundet till kroppen via vår röst. Vi har analyserat röster från ljudböcker och har använt oss av en lyssningsmodell för att byta fokus var vi lyssnade. Rösten i ljudboken bär med sig orden från författaren men även en del av sig själv.

This thesis aim to explain which part sound and music possess as a branding tool. We consider this to be of relevance since there is very limited reseach conducted on the subject. To fulfill the purpose of this thesis we have focused on three main issues. Our ambition is to describe this subject from a marketing perspective with the brand in focus.

Some people do not have the opportunity to visit a physical exhibition because of limited time or long travelling distances, it is here the need for a web-based exhibition arises.This dissertation describes the development of an interactive web-site representing a part of a physical exhibition of over 200 interviews on different peoples immigration to inner Scandinavia. The interviews contain text, audio clip, pictures and video clip.The website contains modern programming technologies such as HTML5, ASP.NET MVC3, SQL, JavaScript and jQuery.A cover of the technologies used and how the project has been designed and implemented is explained in the dissertation. In the end of the dissertation we discuss about how the result of the project follows the goals we set up in the start phase. The result of this project is an interactive and easy to use web-site showing a part of the physical exhibition online. An easy administration to insert new information and edit existing without any major computer knowledge..

Idre Fjäll currently has not full control of how visitors experience their site or if it has good usability. I have helped the company to do a usability test on their website to see how and where any improvements can be made on the page before the winter season 2010. I have also done a survey to investigate how users perceive Idre Fjälls website. Ten people of various ages participated in the survey. All test subjects was recorded with both audio and screen activity during the tests.

The purpose of this thesis is to examine how reading different media forms can lead to different experiences for the reader and how they choose which media form to read. Two questions are posed in the study. Question number one is: How does the media form influence the reading experience of the book and question number two is: What reasons can be seen behind the different choices of media forms?The study is based upon qualitative interviews with six readers using different media forms. Two different theories are used for analyzing the result.

Efter fyra månader som ljudpraktikant på det svenska spelföretaget Starbreeze i Uppsala, var det dags att ta steget vidare i ytterligare fyra månader. Från ljuddesign till scriptning, idéer och tankar, samt en inblick i hur scriptning fungerar. Detta arbete handlar om framtagandet av en ljuddesign-prototyp åt ett externt företags framtida spelprojekt. En utveckling som från början var tänkt att öka kunskaperna om scriptning, och att skapa ett sammanhängande spelscenario, men som sedan utvecklades till att leda mycket längre. Förklaring: Ljuddesign = Ljudläggning av någon form, i detta fall spel.

This study was conducted at a special school for children with autism and developmental disabilities. The study consists of three interviews where pedagogues have different experiences of working with children in need of special support. The aim is to get an idea of how teachers think about working with children autism, but above all to find out what methods and educational tools that are used, and why they are used to best motivate students to a rewarding education. Sense of coherence (SOC) is a central concept and a theoretical basis of the study relating to the student to create comprehensibility, manageability and meaningfulness in life. All of these three are essential for the student to find a predictable environment.From the result shows how schools and teachers use different methods and different tools, but both have a focus to help the student find motivation in the learning process.

Syftet med högskoleavhandlingen var att konstruera en klass-D förstärkare för audio med en DDXi-2161 krets från Apogee. Förstärkaren har en digital stereoingång för I²S-format. Digitalisering av en analog audiosignal sker med codec-kretsen WM8731 från Wolfson. För att möjliggöra implementering av funktioner för digital signalbehandling av audiosignalen ingår en FPGA-krets från Altera i systemet. Gränssnitten mellan codec-kretsen och FPGA:n samt FPGA:n och klass-D förstärkaren är beskrivna med VHDL och implementerade i FPGA:n.

The purpose of this study was to investigate how young adults withunilateral cleft lip and palate assess their own speech and communication,and to let speech and language pathologists make a perceptual analysis ofthese individuals? speech at the age of 19 years. An additional aim was toexamine the relationship between these two different ways of evaluation.Data was collected through perceptual analysis from audio recordings and byusing a self-report questionnaire based on the ICF-structure (InternationalClassification of Function, disability and health). Altogether, 33 peopleparticipated. One third of the participants had no speech deficiencies.

A film can attract all kinds of emotions and moods of the audience through its audiovisual communications and cinematic expression, in which music plays a significant role in both understanding and interpretation of film content.It is interesting to explore the musical significance and the emotional aspect of the film out of a media and communications perspective and visual communications perspective because it?s a subject that belongs to the communications of scientific discipline as film is a media text which is working both as communicative and as audio-visual medium with its expressive aspects.The purpose of this bachelor?s paper is to increase and deepen the understanding of music's function and significant role in context with its reinforcing sense of visual expression in film. More specifically, it aims to explore the musical value of the expressive aspect of the media text in form of film musical Les Misérables (2012), which has been transmedialised from the novel of the same name, referring to the sound, music and song in relation to the film's visual expression.The research questions are at the core of the essay study: "how is music used to reinforce the cinematic visual expression?" and "how can music signify the narrative and highlight the emotional aspect of the film?" The theoretical framework is based on some of the key scholars assumptions such as Michel Chion (1994) and Claudia Gorbman (1987), who share the same theoretical views that the soundtrack seems powerful when it expresses its participation in a scene?s emotional moods as the music follows the scene?s rhythm, the image?s flow and contributes emotional and musical codes of emotions and expressions. According to Chion sound and image interact together to tell a story where sound enrich the image with expressive and informative values.
