Utveckling av nytt koncept för positioneringsslid

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

En lärarkår i förändring? : En studie om bildskapandet av läraren i sin yrkesroll i media under åren 1979, 1989 och 2006.

In this pilot study, we have investigated what the two biggest newspapers Aftonbladet and Dagens Nyheter, and the two largest union affiliated journals Lärartidningen/Lärarnastidning and Skolvärlden has written about teachers in their professional roles, and investigated if and whether their reporting has changed over time. In the study, we have also examined what the newspapers and the union affiliated journals emphasize as status enhancing and status lowering factors for the Swedish teaching staff. We have furthermore analyzed our material through Leif Mathiassons theoretical framework in the anthology Uppdrag Lärare ?En antologi om status, yrkesskicklighet och framtidsdrömmar, in which he describes the creation of the image of the school as a medial and political construction. To reinforce Mathiassons theoretical framework we have also presented and used the agenda theory, the gestalt theory and the priming theory in our concluding discussion.

Variationer av klor, svavel och aska i havrekärna : odlingsfaktorernas inverkan på havrens bränsleegenskaper

The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.

Optimering av ett småskaligtvattenkraftsystem

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Ett annorlunda uttryck : en kvalitativ studie om Feministiskt initiativ och deras kommunikation under valkampanjen 2006

The purpose of this study was to examine the political party ?Feministiskt initiativ? (Fi) and their communication during the election campaign 2006. We wanted to find out what the intention was and how the communication was received by the public. We also looked for signs of congruence between those two sides.Fi is the first political party with a feministic ideology to candidate for the parliament in Sweden. The party is rather new and their political standpoints and internal affairs have often been subject of for debate in the media.We wanted to investigate people?s individual opinions of the matter, and therefore we chose to personally interview a number of people.

Modellering och optimering av Lycksele kraftvärmeverk

Stigande kostnader för bränsle samt pressade elpriser gör att produktionen för ett kraftvärmeverk bundet till ett fjärrvärmenät måste optimeras. I denna rapport presenteras en ?Mixed integer linear programming? modell över Skogsbacka kraftvärmeverk, dess ackumulatortank, extrapannor och Lyckseles fjärrvärmenät tänkt att kortsiktigt optimera energiproduktionen. Kraftvärmeverket har en panneffekt på 50 MW och turbineffekt på 16 MW. Modellen tar hänsyn till fjärrvärmenätets framledningstemperatur och returtemperatur samt hur dessa parametrar påverkar kraftvärmeverkets drift samt hur de påverkar ackumulatortankens lager och laddning.

Många röster små : En applicering av Michail Bachtins polyfonibegrepp på Moa Martinsons roman Kvinnor och äppelträd

The aim of this essay is to investigate to which extent the novel Kvinnor och äppelträd by Moa Martinson can be classified as a polyphonic novel. The concept polyphony was established in literary theory by the Russian language theorist and literary critic Michail Bachtin in 1929, in his book Problems of Dostoevsky?s poetics. In order to understand and comprehend the concept of polyphony I have used an interpretation due to the literature scholar Robyn McCallum. She notes that the characters in a polyphonic novel function as focalizers.

En jämförande studie kring några av dagens produkter inom Store and Forward och Live

SVT is Sweden?s largest TV-network and broadcasts more then 22 000 hours of TV each year. SVT is a public service company where the basic idea is to reflect the world from different perspectives and news is very important for providing neutral and versatile information in a variety of areas. An important part of the flow of information is to continuously receive reports from all corners of the world around the clock. This places very high demands on the technology used and it is important that it function and develops to meet current and future growing needs.

Dietary fibre composition and sensory analysis of heat treated wheat and rye bran

When grains of wheat and rye are conventionally milled, large quantities of bran classified as by-products are left and are mainly used for animal feed. Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. It would also be valuable for the food industry to convert by-products as bran to products with higher commercial values. The aim of this thesis was to analyse the content and composition of dietary fibre of heat treated wheat and rye bran according to the Uppsala method with some modifications in order to analyse soluble and insoluble dietary fibre separately. Half of the bran samples were precooked, dried and roasted and the other half dried and roasted (uncooked).

Medborgarnas Förtroende för EU : En fråga om gemensam europeisk identitet?

Den Europeiska Unionen är en mångfacetterad samling länder med ett brett spektra av historisk bakgrund, geografisk placering och ekonomiska förhållanden. I denna uppsats undersöks huruvida en gemensam europeisk identitet kan bidra till en ökad tillit från medborgarna i unionen till EU som institution.Uppsatsens teoretiska underlag består av tidigare forskning. Denna forskning skapar ett fundament för den statistiska modell som används för att besvara frågeställningen.Med hjälp av data samlad ur bland annat Eurobarometerrapporter tar uppsatsen, via multipel linjär regression, fram en modell som förklarar förhållandet mellan den beroende variabeln ?förtroende för EU? och de oberoende variablerna ?uppfattning av gemensam europeisk identitet?, ?avstånd till Bryssel?, ?BNP per capita? och ?antal år som medlem i EU?.Resultatet visar en koppling mellan en högre grad av upplevd gemensam identitet hos medborgarna i ett land och ett ökat förtroende för EU.Vidare visar modellen ett negativt samband mellan förtroendet för EU och ett stigande värde på var och en av de övriga förklaringsvariablerna. Med andra ord: ju längre avstånd till Bryssel, ju högre BNP per capita och ju längre medlemskap i unionen desto lägre förtroende känner den genomsnittlige medborgaren för EU..

The values is then usedinternally or is sent to other control units on the CAN networks.

Extraktion av polyfenoler från pressrester av röda vindruvor

Antioxidanter är kemiska ämnen som är kapabla till att förhindra oxidation av andra molekyler. Dessa ämnen återfinns i djur- och växtriket och tycks ha en skyddande effekt på cellvävnad genom att motverka skadliga oxidativa reaktioner. Antioxidanter används bland annat industriellt som tillsater i livsmedel och andra produkter i syfte att förhindra oxidativ degradering och bibehålla näringsvärdet i livsmedel. I vindruvor återfinns höga koncentrationer av naturliga antioxidanter, främst i form av fenoliska ämnen. På grund av att vinindustrin bidrar till stora mänger avfall, främst i form av druvrester, är det önskevärt att hitta en effektiv metod för att återvinna fenoliska antioxidanter från avfallet.I detta arbete användes lösningsmedel-extraktion för att extrahera fenoliska ämnen från pressrester av röda vindruvor av varianten Tempranillo.

Från teckning till färdig produktion : en studie av storyboards inom spelfilm och animerad film

In this thesis I focus on the artistry and essential work, behind the scenes that storyboard artists have contributed to, since the early days of film history. The works I will focus on are the important phases of pre-planning of feature films and animated films. I theorize on the aspect of what makes a good story and how it is brought to life on the screen, as well as how the story is actually conveyed with this drawings. The hypothesis maintains the importance of storyboards, as well as defining their main purpose. Using a formalistic point of view and historical argumentation, I examine and compare five different directors´ use of storyboards and how their respective collaborative teams (i.e director of photography, production designer and story artists, editors etc) create each film´s particular nuances and cinematic expressions.

Didaktiska arter

The study intends to find easily recognizable indicator species for water quality in the constructed wetland of Flemingsbergsviken. The study is relevant since indicator species can be difficult to determine for common people. Easily recognizable indicator species could improve dialogue between the scientific community, administrative authorities and the general public. Such species could be used in education systems, associations or in information campaigns. Therefore, I have chosen to refer to these species as didactical species.

Den Jordiske Fadern. Bilden av Josef i barndomsberättelserna i Matteus och Lukas

The purpose of this study is to investigate how the authors of Matthew and Luke describe Joseph; The main aim is to see how the picture of him is drawn in the infancy narratives of their respectiveGospels; what unites, and what distinguishes the pictures of the two evangelists' account of Joseph,as a character and as a father.With the help of both textual and grammatical criticism, this study investigates - pericope bypericope - different aspects of Joseph's participation in the infancy narratives of Matthew and Luke; his relationship to the child and the mother, the terms used to describe him, and his overall modusoperandi. This essay builds its structure upon the individual study of each pericope, with the aim of painting a general and summarized picture.From the outset of already formulated uniting characteristics of the two gospels, as stated in Raymond E Brown's The Birth of the Messiah this study proposes that more can be said about the common features of Matthew and Luke, especially concerning Joseph's both character and relationto the child. First, this study suggests that both Matthew and Luke describe Joseph as the legal father of Jesus; second, both evangelists seems to describe Joseph as observant of Jewish law andcustom.The main impression of the two evangelists' birth narratives is however the differencesconcerning the description of Joseph. This study shows that there is one major common feature: the ambivalence evident in the evangelists' way of describing Joseph. On the one hand, both Matthew and Luke prescribe Joseph some importance; Matthew by describing Joseph and letting him act,Luke by calling him father and parent.
