Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

The discussion concerning what role the church and theology should have in a modern, western society is a question that is ongoing in Sweden as well as in other countries. The present; American theologians Stanley Hauerwas and Max L. Stackhouse have different ideas concerning the identity of the church and theology as well as their relation to the society they are in. This essay surveys their views on the church and the theology and how they should relate to the society. Hauerwas focuses his theology on the church, and the first part of the essay deals with his view on what makes a church, how it differs from the rest of the world and what the church?s calling is.

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

I denna designpedagogiska undersökning behandlar jag frågeställningen: Vad händer i mötet mellan olika generationer när man använder det textila handarbetet som en social plattform där kunskap förmedlas? Med underfrågorna: Vilken roll spelar handarbetet i mötet mellan generationer? Hur påverkar skillnader i förhållningssätt till handarbetet mötet mellan generationer? Syftet med min undersökning är att undersöka handarbetets möjlighet att skapa en social plattform där generationer kan mötas. Jag undrar om det går att synliggöra och tillgängliggöra en äldre generation och dess kunskap för en yngre generation.Undersökningen består av två träffar där en grupp äldre kvinnor träffas tillsammans med en grupp yngre kvinnor för att handarbeta. Det finns i och med träffarna även en uttalad önskan om förmedling av handarbetskunskap. Både de äldre och de yngre deltagarna har medverkat utifrån ett eget intresse och initiativ.

The purpose of this essay is to analyse and understand how branding can take place in a football organisation. Football clubs have for a long time been seen as non-profit organisations but since money have become a main factor also in football these days the organisations are more or less turning in to commercial businesses. Football organisations have for many years neglected the assets of actively contributing values to their brand. Despite that branding doesn't seem to be seen as important in football organisations as it is for real companies who spend a fortune of money on building strong brands, which makes us curious to find out how this approach can be developed also in football. We are also interested in what the characteristics are and which underlying factors that determines the choice of a football brand.

Bakgrund: På uppdrag av regeringen har Barnombudsmannen år 2010 skrivit en rapport där syftet var att ta reda på hur placerade barn och unga upplever sin situation på HVB-hem och familjehem. De intervjuer som gjorts med flertalet ungdomar runt om i Sverige tyder på en negativ inställning till Socialtjänsten som bottnar i en oärlig kommunikation från myndighetens sida men även en missaktning från samhällets sida. Syfte: Med en utgångspunkt i de resonemang som skildras i uppsatsen går det att anta att en placering till stor del har en stark inverkan på den unge på olika vis, samt att det är många aspekter som ska samspela för att vårdformen ska vara den bästa för individen. Uppsatsens syfte är att lyfta fram och synliggöra vilken påverkan och betydelse vården kan ha för den unge under och på vägen ut från en placering samt på vilket sätt. Jag vill även skapa en förståelse för hur det påverkar dennes motivation till en strävan att vilja lämna vården.Metod: Studien baseras på kvalitativ metod med en central utgångspunkt i hermeneutiken, men utgår även till viss del från den narrativa metoden med angreppssättet livsberättelser.

I början av 1950-talet utvecklades en idé att flottan skulle bli lättare. Detta berodde delvis på ekonomiska faktorer samt att flottans större system såsom pansarskepp började bli föråldrade. Den tekniska utvecklingen bidrog även till att system som radarn gjorde intrång. Sjömålsroboten och den trådstyrda torpeden kunde skjutas från mindre plattformar vilket gjorde det möjligt med en lättare flotta. Hotet vid denna tid sågs som Sovjetunionen.

The purpose of this thesis was to study the origin of the local news in local newspapers. Do the news originate mostly from the police, the municipality, from press releases or from the reporters own ideas? We also wanted to find out what kind of content predominated in texts with its origin in press releases respectively the reporters own ideas. Of course we also wanted to find out if there were any similarities or differences between the two studied newspapers.We used a type of constructed week, but with non random selection instead of random. We chose one of each weekday the newspapers were published and studied the news covered in the papers that specific day.

Title: This is not Africa - West African teaching methods in Sweden. This is a work of "translation". The study started with a musical journey to Guinea, West Africa. It was a field study where I had the opportunity to open my senses towards another culture and another kind of music. I found another learning tradition and decided to try to bring it with me back to Sweden, into the Swedish school system.

This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

The Swedish educational system has taken a step toward change in hopes of a better education by presenting a new national curriculum: Curriculum for the compulsory school, preschool class and the leisure-time centre 2011 (Lgr 11). I have therefore chosen to analyze the textbooks Champion 4 and Portfolio based on the objectives and areas of knowledge for grades 4-6 found in the syllabus for English in Lgr 11 in order to find out whether or not the textbooks are in harmony with the syllabus and if the textbooks can be used to help students meet the requirements found in the syllabus for the English subject.The purpose of this study is to analyze selected textbooks for the English subject for students in fourth grade to find out which of the curriculum?s requirements are met for grades 4-6, that is, goals and areas of knowledge and if they can be used in the compulsory school.The results of this study show that the analyzed books can be used in an education that today follows a new curriculum. However the education should not only be based on the textbooks. The teacher must take responsibility for designing an education that suits the intended student group, but also provides students with different learning styles an opportunity to develop in their individual ways.

Den här studien undersöker hur faktorerna etnicitet, genus, funktionsförmåga, generation/ålder och klass ur ett intersektionellt perspektiv skapas, rekonstrueras och samspelar i läslärorna Den magiska kulan och Briljant svenska. Studien har genomförts med hjälp av en kritisk diskusanalys enligt Faircloughs tredimensionella modell och är uppdelad i två delstudier. Syftet är att se hur dessa faktorer skildras samt undersöka samspelet mellan dessa. Vidare diskuterar studien vilka normer och värderingar som kan tänkas förmedlas i och med användandet av de aktuella läslärorna. Studien visar att böckerna skapar och upprätthåller en gräns mellan minoritet och majoritet, där majoriteten tillskrivs en överordnad roll. .

The purpose of this master thesis is to examine how librarians/cultural workers act in projects in order to stimulate and promote reading among children and youth in sparsely populated regions in the county of Jämtland during a period of three years, and if/how these projects differ. The examination is based upon the progress of these projects in four of eight communities. Four librarians and two cultural workers have been interviewed in order to get their view of the proceedings of the projects. The results indicate that the four communities all made up plans for three years but in different ways. They mainly collaborated with the school but also with the board of children's health and the preparatory school.

In today's society the borders between work and leisure blurs out more and more, and just as we might bring our work home, we might as well take our leisure to work with the help of so called smartphones with constant connection to social networks such as facebook and twitter. But what happens when the small talk around the coffee machine in the workplace gets out in public spaces? Instead of complaining to my closest colleague when my boss is acting like a fool or when my workload sky rocketed, I might now instead update my status on facebook with my complaint. But what am I actually allowed to write about my employer? And has the employer any possibility to act legally in respond to what I write?For the younger generation, who more or less is grown up with these social networks, I think this demarcation can be difficult to draw and understand.In this essay I deal with the issue of whether a principle of law, such as the duty of loyalty might collide with my constitutional right to use freedom of speech against my employer..
