Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

Title: "Everybody is talking about reception but what do they really mean?" - Teacher trainers' experience of work with aesthetic communication in perspective of a receiver with a special attention to the reception of music. The purpose of this thesis is to study the notion of reception among a group of teachers at the department of education at Malmö University. Our principal aim is to illuminate reception in an educational context as well as experiences of the teachers´ work with aesthetic communication in perspective of a receiver within the main subject KME (Culture Media Aesthetics). We are paying special attention to the reception of music since this is a part of our profession.

This thesis is about the interaction between composition, notation and interpretation and what occurs between the fields with an extended notation.The purpose of my thesis is to examine the possibilities tothoroughly describe and map the sounding samples through composition prototypes.The thesis has a qualitative approach, and the empirical material consists of different documents about notation and from interviews with musicians and students about the instruments used in the thesis.It also consists of 17 compositions recorded at Örebro University School of Music as an appendix.The analysis shows that the context in which the symbols are found, play an important role in performing them. It also shows that the performers are rooted in a traditional way of performing..

Meningen med denna uppsats är att ge läsaren en förståelse för hur skivbranschen använder sig utav Internet vid marknadsföring och produktlansering, detta har lett till att vi valt att undersöka hur skivbranschen använder sig utan Internet som ett marknadsförings- och produktlanseringsverktyg. En fallstudie har gjorts på två Svenska Independent Skivbolag i syfte att redogöra för hur de använder sig av Internet inom vårt forskningsområde. Studien visade att våra fallstudieobjekt använder Internet som ett komplement och inte som ett substitut för de andra marknadsföringsaktiviteter som de använder sig utav..

With the development of the Internet, illegal copying of electronic documents has become a growing problem. There is an increasing need of prevention in the field of pirate copying. One method is to mark the document by changing some of the words to synonyms. In this way it is possible to construct legal copies which do not differ in content but still are unique. Since the copies of the documents are unique, it is possible to trace the owner of a document and accordingly call him or her to account for pirate copying if several exactly similar copies are reaching the market.

Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

This is a project with the main purpose to create a visual identity and platform for the release of the new started record label Human vs Environment, by finding a form and logotype for the homepage and packaging of the first vinyl ep record by the artist Mr Kaizen. This has also been an exploratory work with the target to get a broader competence in the field of visual communication and increase my understanding of the designs communicative aspects of running a design project with an external partner from concept to finished product..

The culture center studied has gone from being organized by enthusiasts and ideals, to being institutionalized with a educational association responsible for the management. The questions discussed are ? how this change affects the active people in the house and what consequences these changes make for the institution of the house and for the regular management..

Through participant observation in a local promoter group of hardcore punk shows inGothenburg and qualitative interviews with its members I have investigated links between taste in music, values and social structures in the hardcore punk scene. The theoretical framework of this essay is built upon the concept of subcultural capital, which is adapted from Pierre Bourdieu and developed by Sarah Thornton and Keith Kahn-Harris. The result shows how members among the hardcore punk scene create and preserve distinction towards others, while the distinction becomes important benchmarks for including and excluding practices in the scene..

TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications. Other terminals, such as a PC, can also receive TV and radio services. Digital TV and radio can offer additional services such as e-commerce, electronic program guides and content synchronized to the TV and radio shows. If these services are to be received by several receiving terminals with different properties, the services must be adapted to the terminals.

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

Projektets ide är främst att göra byggnaden till en spektakulär och funktionell upplevelse förbesökarna. Varför är detta förslag den bästaför den här platsen? För att den är intressant och blir som ett märke och symbol för Stockholm som Sydneyoperan är för Australien. Dessutom kopplar den till omgivningen med sitt reflekterande fasad och den skapar en ny och spännande inre miljö för besökarna. När man har ett så stort program som detta projekt har bör man ta chansen att skapa att skapa monumentala rum och intresseväckande former.

Examensarbetet har gått ut på att uppgradera ett styrsystem och en operatörspanel för en centrifug i en kemisk industri. Projektets syfte är att centrifugen ska köras på ett mer automatiskt sätt med ett nyare system som har större tillgång till reservdelar.          Centrifugens äldre styrsystem från Siemens har bytts ut mot ett nytt Siemenssystem och den tidigare operatörspanelen från Siemens har bytts ut mot Beijer Electronic E1070 operatörspanel. Styrsystemet programmerades sedan i Siemens Simatic Step7 och operatörspanelen programmerades i Beijer Electronics E-designer.                Efter att programmeringen var klar testades kommunikationen mellan styrsystemet och operatörspanelen innan inkopplingen av det övriga systemet skedde.
