Testsystem för utredning av integrerad styrning för RC-helikopter

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

Hitstandard: Myt eller verklighet?: Finns det verkligen en idealform vid komponering av populärmusik?

Det har under lång tid existerat en diskussion gällande huruvida det finns en formel för att skriva musik som tilltalar alla. I detta arbete gjordes ett försök att ta reda på om så är fallet. Detta gjordes genom att analysera tio listettor från Trackslistan och identifiera gemensamma nämnare såsom form, tempo, tonart, instrumentsättning och ackordföljd. Med hjälp av de gemensamma nämnarna skapades en idealform som borde tilltala flertalet lyssnare. En låt komponerades efter idealformen, och jämfördes i lyssningstest med andra variationer på låten för att se om försökspersonerna föredrog idealformen.

Cykeltouren

The number of locals in Stockholm who chooses the bike in front of public transport has increased significantly in recent years. The product purchaser of this project, Joakim Victorin at Sigma AB, has a keen interest in cycling, which resulted in a fairly obvious topic of this project; through a web application Sigma AB wanted to make it possible to handle results from professional as well as amateur competitions in cycling.The purpose of this web application is to simplify reporting and handling of competition for both small and bigger bicycle races. By providing the users of the system a platform independent client, any available device may be used.This thesis has followed the development principles which prevail on the ASP .NET MVC 3 concept. When developing the system the Microsoft Visual Studio 2010 development environment was used. The framework and the pattern of ASP .NET MVC 3 is a prominent part of today?s web development.

Dialekter i svenskämnet : En studie av dialekters utrymme i undervisning och läromedel i gymnasieskolan

Dialekter av olika slag är något som de flesta kommer i kontakt med dagligen, genom möten, via TV eller radio och även i skolan. I denna uppsats undersöks hur dialektundervisningen ser ut i skolan och hur stort utrymme momentet får. Detta görs med hjälp av en enkätundersökning som sammanlagt 34 informanter i Karlstad, Södertälje och Umeå fyllt i. Dessutom analyseras dialektavsnittets utrymme i elva läroböcker för kursen Svenska 1, för att jämföras med undervisningen.     Resultatet visar att lärarna i snitt undervisar 5,27 lektioner om dialekter, där lärarna i Södertälje uppgett minst antal lektioner. Vidare visar undersökningen att flera faktorer påverkar hur stort utrymme momentet får, bland annat hur pass intresserade eleverna är av dialekter.

En retrospektiv fallstudie av konservativ behandling av intraartikulära hovbensfrakturer, typ II och III, hos rid- och körhästar :

Hospital records of 32 non-racehorses referred to Skara Animal Hospital and Halland Animal Hospital, Sweden, between January 1995 and September 2001 for intraarticular fractures of the third phalanx, were reviewed, and follow-up information on final outcome was collected to determine whether any injury or treatment factors could be associated with the outcome. Mean age of the horses was 8.3 years (range, 1-20 years), and follow-up time ranged from 1 to 7 years after injury. In 11 (34%) of the horses, injury involved the front limbs. Twenty-two (69%) horses returned to their original level of use. There was no statistically significant correlation between outcome and elapsed time from injury to treatment, treatment variables, or bony union in the present study.

En organisation i förändring. En fallstudie om Lantbrukarnas Riksförbund och riksförbundsstämman.

AbstractThe Swedish agricultural organisation, LRF, stands in front of many changes and the work with the changes in the organisation has caused some conflicts at the top. Is it like Michels say that it's a few people at the top that rules? The case with LRF shows to be something different, since the president Caroline Trapp was re-elected. The election committee proposed a new president, but the assembly had another opinion and re-elected Caroline Trapp. This shows that the opinions at the top were not the same as among the members of the organisation and the election committee couldn?t rule over them.In this essay I try to understand what kind of organisation LRF is and what made this case special.

Kristdemokratiska partier i förändring? : En partiideologisk studie av tre kristdemokratiska partier över tid

Denna uppsats undersöker KRAVs möjlighet att förändra jordbruket i mer hållbar riktning genom att studera mjölkbönders inställning till ekologisk produktion i Halland. Både ekologiska och konventionella bönders syn på ekologisk produktion beaktas. Genom att jämföra KRAVs arbete med de av mjölkbönderna upplevda hindrena för omställning syftar denna studie att ge klarhet i certifieringssystemens effektivitet som politiskt styrmedel. Resultaten visade att de av bönderna upplevda hindren för omställning till ekologisk produktion till stor del grundade sig i fördomar och feluppfattningar. Undantaget var markbrist, vilket av båda grupper identifierades som det största omställningshindret.

Whispers in the forest : a field study about communication within Vi-agroforestry

The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data. I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003) Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.

"Man tiger, biter ihop och går vidare?" : en representationsteoretisk analys av talet om sexuella trakasserier i en svensk kulturdebatt

The purpose of this essay is to analyse how medial representations in a specific cultural debate expresses thoughts about gender, power and speech. The debate in question took place in Sweden 2010 and was about an inspection of sexual harassments in the Swedish acting area, made by Sveriges Radio, Ekot. This essay examines the made representations of the debate, with a feministic point of view and concludes that a male gaze shapes the form of speech and gives the debate a discourse sort of reasoning about gender. The special discourse formatted in the examined area contains a certain conception of power and the structure of power, which is also explained by the male gaze and the meaning of post-feminism..

Telekrig mot bandspridningsteknik

I denna uppsats betraktas två olika bandspridningstekniker och vilken påverkan de har på telekrigsförmågan. Uppsatsen svarar på frågan:Vilka möjligheter finns att bedriva signalspaning och störning mot radiokommunikation som använder bandspridningsteknikerna frekvenshopp eller direktsekvens?Inledningsvis beskrivs en modell för telekrig mot radiokommunikation, ?telekrigcykeln?. Därefter beskrivs principer för ett radiosystem samt de två bandspridningsteknikerna frekvenshopp och direktsekvens. Slutligen analyseras bandspridningsteknikernas påverkan med hjälp av telekrigcykeln och resultaten diskuteras.Uppsatsen kommer fram till att båda signalerna går att spana mot, direktsekvens innebär större svårigheter för signalspaningen än frekvenshopp.

The Surveillance Camera Players : Ett konstnärligt motstånd mot övervakningssamhället

The purpose with this essay is to examine how arts and politics integrate to raise urgent messages and call upon social changes. Performance art as an artistic manifestation against the surveillance society has been studied to clarify this integration and through an empirical examination of the anarchistic performance group The Surveillance Camera Players. This group formed in New York City 1996 as a manifestation against the increased use of surveillance cameras in public places in Manhattan. Through performance in front of these cameras, The Surveillance Camera Players are able to express their protest against the surveillance society which, occurring to them, violates citizens constitutionally right to privacy. The development and signification of the surveillance society are examined through theoretical perspective by foremost Michel Foucault, but also by contemporary scientist in that field.

EU:s svårföränderliga jordbrukspolitik - En studie om varför CAP är så svårföränderligt ur ett nyinstitutionalistiskt perspektiv

The European Union's long-term budget negotiations during the summer of 2005 were obstructed from being successful due to a quite fierceful debate about the future guidelines of the Common Agricultural Policy. A quarrel about money and who gets what, was the common answer as to why it took the European leaders six months to accept the budget, and quite rightfully. This essay, however, goes beneath those explanations and tries to see what other reasons there might be for such a phenomena.With a new institutionalistic approach this study seeks to see what underlying reasons for why an institution such as CAP is so resistant to change. With special attention to the new historical institutionalism and the rational choice institutionalism the study successfully shows that though the front laying reasons to the problems with the budget might have been economical, several other factors also affected the outcome of the budget negotiations.Structures, national identity and decisions taken when outlining the Common Agricultural Policy in the 1960's still affect the European union, its members and foremost of all, the Policy/institution itself..

Temperaturens, kadaverålderns och radiopulssekvensens betydelse för bildkvaliteten vid magnetresonanstomografi av tarsus hos häst

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.
