Autonom bil med enkapseldator och ultraljudssensorer : tillämpning av en Arduino mikrokontrollerplattform och HC-SR04 sensorer

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

Stubbtransporter och bränslekvalitet hos stubbved :

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

Föroreningar orsakade av stenar inblandade i barrmassaved

Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.

"Det internationella kortet": En undersökning av det politiska samtalet kring Ålandsexemplet

Over the past few years the Åland islands have attracted growing internationalattention as an example of how to successfully secure the position of a minorityregion, and in the current situation the government of Åland has an intention toextend the efforts of spreading the example of Åland. The purpose of this essay isto shed light on the political discussion about the example of Åland, andinvestigate the underlying political reasons for emphasizing the example of Ålandinternationally. Through interviews with leading politicians on Åland I analyzeÅland as a norm entrepreneur. The research shows that besides altruism, selfinterestis a factor behind emphasizing the example of Åland. The essay showsthat the theory of norm entrepreneurship also can be applied on an autonomousarea, but instead of influencing international organizations themselves, theautonomous area use norm entrepreneurship as a tool for influencing domesticpolitics..

Barns lek och autonomi i förskolan : En filosofisk granskning av barnets och lekens etiska ställning i den svenska förskolan

This essay is a philosophical investigation of the relation between children and their play. My aim is to see if children are autonomous when it comes to their play. Is there a moral boundary between those who take part in the play and those who do not? This topic is especially important when it comes to the moral status of a child in the Swedish pre-school. How should educationists act when it comes to children?s play?  Through an analysis of the notions of play and autonomy I show that play can be understood as something of a moral value to the child and if children should be seen as autonomous when it comes to their play.

Mekanisk säkring av helikopter på fartygsdäck : en konceptuell fallstudie av Saabs UAV-system Skeldar M

Den senaste trenden inom flygvapenindustrin är utveckling av obemannade farkoster. Den svenska vapenindustrikoncernen Saab AB följer denna trend i och med den stundande introduktionen av företagets obemannade helikopter Skeldar V-150. Som ett led i vidareutvecklingen av detta system finns planer på att även lansera en marin variant, kallad Skeldar M. Tanken med denna marina variant är att möjliggöra fullständigt autonoma starter och landningar från fartyg. För att kunna genomföra detta på ett tryggt sätt även i hårt väder krävs att helikoptern hålls säkrad på fartygsdäcket såväl innan start som efter landning.Uppgiften för detta arbete har varit att ta fram koncept för hur ett sådant säkringssystem skulle kunna se ut.

Tidsstudie av containerhuggbil

The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.

Inkluderande engelskundervisning : En fallstudie av Autonomous Learning och Europeisk Språkportfolio som metod för inkludering av elever i svårigheter

Bakgrunden till studien är att forskningen visar att elever i svårigheter utvecklas mest kunskapsmässigt och mår bäst socialt av att inkluderas i klassens undervisning. Trots detta finns det väldigt ofta en önskan att exkludera dessa elever eftersom många lärare inte anser sig klara elever med specialpedagogiska behov inom den ordinarie undervisningens ram. Detta har lett till en rättvise- och inkluderingsdebatt såväl som en debatt med ekonomiska förtecken. Frågor som lyfts är ?Var mår eleverna bäst och finns det metoder som fungerar så att alla elever kan inkluderas?? Min studie syftar till att undersöka möjligheten till ett inkluderande arbetssätt i engelskundervisningen med hjälp av Europeisk Språk Portfolio och Autonomous Learning.

Merkostnader med vinterväghållning för Grot-transporter orsakade av väglagring.

Fuel wood is currently the third largest assortment from the forest in Sweden after pulpwood and lumber. Branches and tops i.e. logging residues are one of the assortments of fuel wood which is a common by-product after harvesting nowadays. The way to utilize, disintegrate and transport the logging residues varies between northern and southern Sweden. Branches and tops are collected throughout the year at appropriate stands, but are consumed mainly wintertime.

Konst Kräver Offer : En analys av Nathalia Edenmonts konstnärskap i ljuset av Pierre Bourdieus kulturteori

Nathalia Edenmont is a controversial and uncompromising photo artist who has caused the whole world to rage over her obscene photographs. In this thesis I have researched Edenmonts artistry with help of the sociologist Pierre Bourdieus field analysis. By using Bourdieus's different field concepts I have researched Edenmonts artistic career by concepts such as habitus, consecration and different principles.The starting point of this research has been that Nathalia Edenmont is in the autonomous artistic field. I give examples of images that have been highly debated and I have collected information of how Edenmont sees her own images and her artistry. In this thesis I show amongst other things an example with Edenmonts photograph of dead rabbits with Elizabethan hair styling, cut up mice that work like finger puppets and children who are bound up in wire.Nathalia Edenmont autonomous artistry is deeply rooted in her background and the environment in which she was raised.

IT-stöd för träning av etisk kompetens

Ethical competence is an important precondition when people are to respond to moral problem situations as efficiently as possible. In these situations it is not easy to make choices and decisions, especially when many stakeholders are involved with various opinions and interests.The purpose of this thesis was to generate a web-based support tool to train and promote ethical competence of the users of this tool.We first created a theoretical basis by studying the major theories of ethics in general and ethical competence in particular. The importance of ethical competence and its main subject, namely, the autonomy in the theoretical part described and specified. In addition has the practical ethical reflection over morality preferred and characterized to the classical ethical passivity over morality. We have also preferred and characterized the autonomous thinking to the heteronomous one.Based on the theoretical base a prototype tool to support the training of ethical competence was designed and developed.

Läraren i praktiken : En studie om lärares förmåga att inspirera och medvetandegöra elevers inlärning, samt omforma sina akademiska ämneskunskaper

Denna uppsats, Läraren och den praktiska verkligheten, handlar om hur lärare gör föratt omforma sina ämneskunskaper till ämnesdidaktiska, vilka metoder de använder iundervisningen för att medvetandegöra elevernas inlärning, samt hur lärarna gör för attutmana och inspirera elevernas lärande och kunskapsutveckling. Teorierna som använtsi studien är läranderum, proximala utvecklingszonen, autonomous learning, learning tolearn och pedagogical content knowledge, vilka även ligger till grund för denanalyserande delen.Resultaten i studien visar att en fungerande gruppdynamik är avgörande för en godarbetsmiljö, en ständig dialog utifrån elevens perspektiv bör föras för att skapamedvetenhet hos eleven gällande lärprocessen. Utveckling av självständigt lärande skergenom tydlig kommunikation mellan lärare och elever, det vill säga att läraren är tydligmed anledningen till arbetsområdet, informationen kring anvisningarna, samt finns somen tydlig vägledare för att guida eleven genom ämnet. Vidare handlar omformning avämneskunskaper för lärare i praktiken om att reflektera, utvärdera och utvecklaplaneringen och den genomförda undervisningen..

Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.
