Examensarbetet utfördes i samarbete med Transient Design som är ett företag i HiFi branschen. Examensarbetet behandlar utvecklingen av en skivspelare vilket hade som mål att ge förslag på ett designkoncept samt bidra med relevanta tekniska lösningar.Arbete inleddes med en förstudie som syftade till att bygga en bra grund för att på ett bra sätt kunna utföra resten av arbetet. Den stora delen av förstudien var dels en marknadsundersökning av enklare typ avsedd att skapa en bättre bild av den tänkta målgruppen och dels litteraturstudier inom ämnen som vibrationsteori och mätutrustning. Då en stabil grund för arbetet formats gick projektet in i idégenereringsfasen där en stor mängd olika förslag på både design och tekniska lösningar var resultatet. Utifrån denna stora grupp med förslag utfördes en rad urval med vidareutveckling däremellan.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

Several theoretical models of change exist concerning attachment, but an integrated view and knowledge of the role separate factors of change play for the individual is lacking. This phenomenon is hereby studied by semi-structured interviews of 20 persons. Change and factors of change are examined statistically with affectregulation as measure of attachment. The results show that these individuals´ changes are small and mostly towards secure attachment. Metacognition is related to greater change towards secure attachment.

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.

The aim of this study is to fill the gap in mathematics education research concerning the relationship between identity and positioning in mathematical collaboration in groups. This study elaborates on the relationship between how pupils see themselves as math students in sixth grade, how they show their identities as math students, in contrast to how they position themselves reflexively in group collaboration while engaging in mathematical problem solving. The theoretical concepts linked to this study are discourse, identity and positioning. Discourse is used to describe and form the setting and context of the study. Identity is seen as a transient and elusive concept formed by the students own perceptions of self through narratives.

Ett digitalt vågfilter av Richardstyp har implementerats i en FPGA på ett utvecklingskort. Sampel kan skickas till filtret och mottas från filtret via serieporten på en dator. Metoden som användes är att en modell av filtret konstruerades i Simulink. Filtret har modifierats med avseende på skalning, brus och stabilitet. VHDL-koden till filtret genererades i Simulink genom att bygga modellen av Xilinx Blockset.

The Division of Language and Communication at Chalmers uses a web-based language tool, named EngOnline, to teach English grammar. The language tool suffers from some shortcomings. These include stability problems and an outdated interface but, above all, there is no documentation. Because of the lack of documentation and EngOnline?s need of maintenance, the Division of Language and Communication has decided to replace the language tool with a new and well documented one.The new language tool was developed using an agile work process; detailed documentation was replaced with more efficient communication.

This essay deals with development in Latin America. We have picked out some factors that the theories in development theory emphasize on. The first section of the study consists of a statistical analysis, were the main purposes are to study the relationship between the independent variables and the dependent and to choose which two countries we should focus on in the next section. The countries we decided to study were Costa Rica and Nicaragua, because these countries have shown very different levels of development. From this study we have concluded that political stability, economical investements and human investments are the most important factors when creating development..

The aim of this study is to look how the Social Service has handled custody issues. The study has a legal and social aspect with a purpose to investigate how the law affects the social administration as well as the family. During a period of one year a quantitative and qualitative study was performed within the social administration in a nearby community. The study focus is partly on the relationship between the law, family and society. The main questions have been: Which one of the parents, mother or father, did in fact get the custody and why? How has the children?s point of view been reported in the inquiry? A child needs a well organized everyday life in a preferably conflict free environment.

The purpose of this study has been to look how pedagogic process interacts in horse riding lessons. In order to research this problem I have used an ethnographic approach and during a week I observed ten riding lessons in two separate Riding house in the south of Sweden. In my theoretical frame I have used Michel Foucault ?Discipline and punish? as a toll to make clear how dominance and submission is present and active in the horse riding education. The conclusion shows how dominant power rules by its presence and creates submission, stability and feeling of security. The discipline is used to create a feeling that will bring the riders to new experience and develop their talent.

Olyckor är vanliga inom sjöfarten. För den akut medicinska behandlingen finns god beredskap ochtydliga riktlinjer. För den akut psykiska behandlingen saknas klara råd. Denna studie undersökerrådande riktlinjer och praxis för det psykiska stödet. Studien syftar på att klargöra vad det finns förmöjlighet att utveckla det psykiska stödet i det akuta skedet efter en incident ombord på svenskafartyg.

In a sequence described in the next paragraphs, I remove the poorly insulated roof of Gustavsberg Porcelain Factory and make new use of its  foundation. The monolith cement slab, once supporting heavy industrial machinery, is now the site of lakes and other movements:The top floor area is split, and a new built volume, one story higher, overtakes the southern half resting on the factory?s basement, digging into it at its western and eastern ends. Striking horizontally, the fissure exposes a long central axis, taking advantage of the factory?s horizontality to articulate vastness .

With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.
