The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

AbstractThe main purpose of this essay is to examine if media-sport influence pupils in their physical education and if the teachers understands it. At the same time the aim has also been to investigate how the teachers can get along with the media influence in their teaching. We have also investigated what teachers in physical education think about the curriculum and if there is space for a teaching method that respect the pupils will.The essay is an empirical qualitative study built on open-ended interviews with 3 respondents from two schools in the county of Värmland, Sweden. The range of qualified teacher is restricted at this school. We asked 5 teachers to join, but only 3 were accepting to join our study.

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

WebGL is a standard for drawing graphics in a web browser. Currently it isn?t widely understood how consistently WebGL performs across a majority of the de- vices that support it. Determining if an image looks correct to a human observer is an interesting problem. The solution for this is useful when developing WebGL applications, since a developer could make better informed decisions during de- velopment.

The aim of this study is to increase knowledge and understanding regarding which institutional demands can be identified by social welfare secretary?s in their work with juvenile offenders. The study uses organizational theory to try and find different institutional strategies that social workers use to handle such demands. The study takes a qualitative approach and consists of six semi-structural interviews with social welfare secretary?s who work with juvenile offenders.The results of the study show how institutional influence comes from various organizations and institutions such as media, legislation as well as the police and justice system.

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

The aim of this Master?s thesis is to examine how representations of identity construction are performed through the characters in the novel Snabba Cash by author Jens Lapidus. I examine what means the characters are using, and how the identity construction processes are related to the idea of modern society. For a theoretical background I use sociologist Anthony Giddens? theories regarding modernity and self-identity, to study general identity construction.

This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.

Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..

The study's aim is to implement a textbook analysis and examine how women are described in history textbooks for high school and in the curriculums Lgy 70, Lpf 94 and Gy 11. The study has a gender perspective and the study's purpose is to make a comparative study and compare textbooks with the current curriculum and compare the results with each other to see if there has been any change over time. The survey's material is three editions of Alla tiders historia from Gleerups förlag. The study refers to editions from 1989, 1996 and 2011. General parts from Lgy 70, Lpf 94 and Gy 11 are also central for my study.

Holmen Skog has in some places in their operation area access to timber trucks with centre mounted scrapers. They make transportation more flexible and reduce reliance on contractors for road maintenance. The trucks with centre mounted scrapers have a higher tare weight, making them less productive and therefore they receive compensation with a 0.75 % increase on transportation price. The purpose of this study was to investigate what actions a timber truck with centre mounted scraper can perform with acceptable quality in winter, and to examine if it is an economically profitable solution for the truck operator and charterer. The study was done in three stages; interviews, performance analysis of the transportations carried out and an economic analysis with the help of Sven Erik Gilles spreadsheet tool. The study included the districts Delsbo and Hudiksvall.

This work is designed to monitor developments in the relationship between teacher and student in the school environment, but also outside, from the 1950s until today. The survey was based on four interviews with teachers in the same age, and based on their life stories. Their experiences range from student to novice teachers and a long working life until retirement. In addition, all four children has a parent perspective. The following issues have been focused:                      1.What factors have been crucial in teaching elevrelationens development from the 1950s up     to today?                      2.

The purpose of this study is to describe and analyzes how the bookmobile librarians approach to purchase and selection and the range of views that may exist. The study is based on a qualitative method using a document study and three interviews included. The document study looking closely at public libraries library plans in Vastra Gotalands county. The qualitative interviews gets a closer look at librarians´approach regarding the purchase and selection and also if there are any similarities or differences between mobile library activities versus the main library.The theoretical framework is based on Sanna Taljas study where she has identified three different perspectives on the library´s music department. These are categorized as the interpretative repertoires and involves three categories of approach to quality.

The objective of this essay is, from the golf perspective including the golf courses' physical attributes, golf club management, members of the golf club and golf course designers, to explore possibilities for making existing golf courses more multifunctional. The purpose of this is to increase the understanding for golf courses' role as part of the landscape and comprehension regarding possible opportunities around them to exploit and develop.The increased pressure of population in peri-urban areas has resulted in a greater need for accessible recreation, particularly in the isolated farmland. As a result, land is sometimes used against landowners' will, which is a deficiency that is the basis for many conflicts between farmers and landowners.In the current situation, there is a negative trend in golf with reduced interest and fewer golfers than in the past. As a result, many of Sweden's golf courses have financial problems and are therefore trying to find new ways to avoid bankruptcy. Sweden's existing golf courses occupy about 30 000 hectares of land, of which a very large percentage are located in peri-urban areas.

The term Temporary places could be used to describe a wide range of shapes, functions and not least different time sets . In this thesis, however, the intention of temporality should be seen as the main definition regarding this subject. This thesis is based on a literature study and the aim is to explore temporary places, their values and their functions. Furthermore, the purpose is also to highlight temporary places as a method to be used by urban planners, in order to create more flexibility in the city planning of today. The thesis describes the underlying factors and conditions creating an increased interest in flexible planning. Furthermore, a number of tactics and applications are presented, all drawn from current research on the topic.
