Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

A product and design development of a household device which shall dry food waste has beencarried out in collaboration with Smedlund Miljösystem AB.This project has been implemented through several brainstorms and a questionnaire study.A great insight of how it is to work in a project in real work life has this project been givenme. This is a slightly less straight road to a conclusion than in the academic world that I amused to..

Today, branding is not a phenomenon but rather a prerequisite for a brand to be able to both survive and grow stronger. During the last couple of years, personal branding has come to be an established term, just like corporate branding. With the growth of the social media and the thousands of ways to interact with each other personal brands face great competition. It is more difficult than ever to maintain a strong brand, partly because of this. There are several growth options for brands.

The purpose of this master´s thesis is to examine how the cultural exchange function of Swedish libraries may be perceived on their websites. A further intention is to examine how the library websites are used at the present. Two quantitative web-based surveys have been sent out to a great number of Swedish public libraries. The first survey was directed to the webmasters of the libraries, in order to review the different services offered by the Swedish library websites of today. The second survey was conducted with library directors, in order to visualise what services they consider ought to be present on their own library website.

Background: Each year, over one million people around the world die as a result of suicide. About 1500 of those are in Sweden. In each case an estimated six kindred?s are to be affected. These people are in great need of support.

EU-NAVFOR är den första insatsen som den Europeiska Unionen skapat och den första okonventionella konflikten till havs som ska bekämpas med konventionella medel. Forskningsläget angående hur dessa konventionella styrkor ska agera mot denna typ av motståndare är väldigt begränsad.Syftet med denna uppsats är således att undersöka om Wayne P. Hughes konventionella krigföringsteorier är användbara i en nutida konflikt samt att se om det finns några likheter eller skillnader mellan dessa teorier och den taktik ME02 använde sig av under insatsen utanför Somalia.Denna uppsats baseras på en kvalitativ metod där Wayne P. Hughes teorier om ?The Great Constants? studeras och beskrivs för att sedan nyttjas som analysverktyg i en teoriprövande fallstudie på ME02.

When the Eolshällproject was completed for the first time, a great deal of moisturedamage was discovered. Therefore the structure completion was removed andreinstalled. The project was originally planned to cost a total of 126 million SEK, but thefinal costs landed on 271 million SEK. What caused this failure? Were the designs poor,was the technology used too advanced, or was the project not managed properly?Based on the Eolshällproject, theses will be presented about what may have caused themoisture damage.

The technical evolution has a great influence on the public libraries. Electronic media becomes more and more common. This Master´s thesis is based upon the Swedish Library law 9§ (SFS 1996:1596) which says: Public- and school libraries should pay special attention to children and teenagers by offering books, information technology and other media, adapted to their needs, to encourage development of language and stimulate reading. From this point of view we have examined why the children´s departments in public libraries offer CD-ROM games which are based upon characters from the literature, how they are used in the daily activity and how they can contribute to the development of the children´s department.We have made literary studies and empirical investigations including interviews, observation studies etc. The results from this studies shows that both young and adults appreciate the CD-ROM games.

Background: The amount of elderly patients who?s suffering from dementhia increases every year. Many of these patients develop and decrease in their cognitive ability. The development can lead to people's communication skills deteriorate. It can be a problem for the nurse to communicate with these patients.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Libraries are often associated with positive values such as democracy and equal rights. The contents of the literature on offer should therefore be of great interest to the librarian, the supplier of said literature. The topic of this Master?s thesis is the popular literary genre known as chick lit. The purpose is to investigate the love theme in Swedish chick lit, and how it relates to Anthony Giddens? theory on love in late modernity.

The philosopher Heraclitus has been renowned for a great amount of time. Despite that fact the remaining fragments of his work have just recently been assembled to the composed form they have today. Among these fragments there are a couple of terms that stands out amongst others; one of them is the term logos. The main focus of this thesis is devoted to the mystery and usage of the term logos, which comes into a great display in fragment number 50.The ambition of the thesis is to evaluate and compare three interpreters? readings of Heraclitus while having a close focus on his usage of the word logos in fragment 50.

The aim of the thesis is to study young peoples, defined as boys and girls between 14 and 16 years old, attitudes to library in two municipalities. Notwithstanding the fact that young people, and children, often is given priority in library work, the reality often seems to be another. Attitudes are founded primarily in childhood and therefore it is of great importance to examine how young people regard libraries. Besides studying former research about young people and libraries that has been performed on library and information science, we also have been using concepts and theories from social science. We give a brief outline of youth research and its development and look at official records and legislation to see if and in what context young people are mentioned.

This essay is about power in the classroom. It is about the power dimension of the student-teacher relationships that arise in that space. The overall aim has been to investigate which categories are fruitful in a power analysis of these relationships. My aim has therefore been to develop power categories and to use them to identify and to categorise cases of power interaction that take place between those particular actors in that particular setting.In order to gather material for my study I have both read literature that approaches the study of the student-teacher relationships from a power perspective and done a series of observations in a high school.My theoretical frame comprises a concept of power and a series of power categories. These categories include strength, authority, inducement, coercion, violence, resistance as well as to possess power, to have power, to exert power, the scope of power and the base of power.

The knowledge of early employment experiences has evolved over the last decade in countries such as Australia and Great Britain. In Sweden, this type of research is still unusual and the aim of this study was to break new ground by highlighting some areas that could be of extra interest in the Swedish early employment research to come. A focus in the study was to give an overview of what job sectors school students work in; and the amount of jobs aquired through school-organized work placement, private social networks or personal marketing of own merits. In addition to this, a multi variate analysis was carried out to find patterns in the picture of early employment experiences among students at upper secondary school. The findings of the study has relevance for ways of conducting career counselling and therefore the general aim of this study is to point out the importance of developing the practises of vocational psychology.A survey among 74 teenaged school students with economics as their main subject has been carried out in a mid-size Swedish city May 2012.
