Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.

We came in contact with the project "Grönplan Danderyd" that aims to create a green structure plan for a municipality of Stockholm called Danderyds kommun. Our thesis is a part of this project and makes it's contribution through the gathering and systematization of the knowledge of the functions of an urban green structure. It also makes a contribution through suggesting how this knowledge can be applied during the construction of an urban green structure plan. We found that "Stadens parker och natur", published by the Swedish National board of Housing, Building and Planning, was a recurrent source of information in the green structure plans that we studied. We saw a need of complementary additions and updates to the rather old report and found literature that adds the developments of the last decade. First of all we have chosen to make themes based on the functions of a green structure that were presented by 'Stadens parker och natur'. The themes we suggest that a greenplanning document manage are: Recreation, Pedagogies and Heath, Biological Diversity, Green structure in the History of Building Cities, Cultural Identity, the Health of the City, Biological Technology in the Municipality and Use and the Users. We found good examples of how to handle these themes in documents that handle greenstructure planning from the municipalities of Göteborg, Strängnäs, Eskilstuna, Malmö, Lund, Västerås and Uppsala.

This thesis is a discourse analysis analyzing public library librarians' talk on the subject of public library meeting places. Within the field of Library and Information Science the public libraries' functions as social meeting places have been scrutinized for more than a decade. Researchers in the Nordic countries in particular have looked at library users' use of the library space and have highlighted the sociologic dimensions of the public library and the meeting place functions. Few however have paid much attention to the library personnel's point of view. The discourse analysis perspective is about language use and how people construct the reality.

This report explains how different communication tools can be used in a company?s intranet. It gives a short description of the different parts in an intranet and their field of application, and what communication means. It?s only the communication tools that the company uses that we are illuminating in this report.

The aim of this paper is to highlight issues and potential problems regarding conservation inan exhibition situation. The thesis presents a case study from the Röhsska museum, inGothenburg, where an interior of painted tapestries was currently being conserved andrestored. The study includes general history about the painted tapestries, conservation historyand information about the current treatments.The painted tapestries originates from a former manor [sv: säteri] in Gothenburg calledHökälla and were donated to the Röhsska museum in 1916. The tapestries were a part of themuseum?s permanent exhibition until 1996, when it was dismounted and put in storage.

The author has, with the help of AK Consultancy Indoor Air AB, formed a series of questions regarding moisture problems in buildings and how these are handled in extreme climates with high temperatures and a high relative humidity. Furthermore to analyse and indentify key material that makes a construction safe against moisture problems. Ventilation, AC and the choice of materials have in a later stage of the thesis been investigated to enhance the knowledge of moisture protection. The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.

Since time immemorial, nature has been conceived of as a female entity. This ancient concept is also a recurring element in contemporary Swedish horror fiction. The purpose of this thesis is to compare the feature of nature in the selected works of Anders Fager, Andreas Marklund and Frida Arwen Rosesund and in what ways these respective depictions rely on a tradition where nature is gendered female. The theoretical starting-point for this comparative study is ecocriticism and its subcategory ecofeminism, which are modes of literary criticism where the role of nature in general, and its female connotations in particular, are appreciated as significant literary features. For executing an analysis that goes beyond what is explicit, the exploration of these three writers? texts also adopts a psychoanalytical perspective.

I did my degree project together with Universeum AB. The project had the work title: children?s world and the aim were to give children between 3-8 years old a place that was especially made for them. With their interests and needs in mind the area should trigger play but also learning through a well planned pedagogical environment.I did this project because I thought this was an excellent opportunity to really practise my new gained skills I had learned during my two years in CCD (Child Culture Design). It also gave me the opportunity to actually see how well my knowledge was working when it was put to the test, and I did learn a lot from this.Together with a crew of 6 people I developed and designed the area.

AbstractPurpose / Aim: The purpose of this study is to find out why people look at K-1. I wanted to investigate what it was about looking at televised martial arts, specifically K-1, that attracts peoples attention and interest, and what it needs it satisfies within the viewer.Material / Method: This study consists of three separate parts, where I investigate and analyse the producer side of K-1, the receiver side, and the program in itself as a media text. For the producer part I performed interviews with the chairman of K-1 Sweden, the production manager at Eurosport Sweden and the Eurosport K-1 commentator. As for the receivers I interviewed six people who watch K-1 more or less regularly, in order to find out why the watch the show and what it gives them. The program text analysis I performed on two K-1 programs from Eurosport, and I based it on previous studies done of similar and other kinds of programs.

This report describes an analysis of WebGL together with JavaScript with the aim to examine its limitations, strengths and weaknesses. This analysis was performed by building a 2D game engine containing some dynamic elements such as water, smoke, fire, light, and more. Different algorithms have been tested and analyzed to provide a clearer picture of how these work together. The report will go through the most basic functions of the game engine and describe briefly how these work.The result shows that JavaScript with WebGL can be considered to be a potent toolsets, despite the difficulties caused by JavaScript.In summary, similar projects can be recommended as Javascript and WebGL proved both fun and incredibly rewarding to work with..

This project is an attempt at creating a bag that is both functionaland has an interesting and relevant visual appearance. I have found that a bag that is functional usually have adapted certain aesthetics which are appealing only to a very limited target group. At the same time many bags that are more focused on style can be downright disabling to the carrier. I wanted to create a functional bag, and to explore new functions doing this, while working with aesthetics that stayed relevant and interesting to my target group. The bag was designed for the company Åhléns and their label WERA Stockholm, and theircustomers was the target group.

During the late 19: th century the park Tivoli in Halmstad, today called Norre Katts park, was known as one of the most beautiful amusementparks of southern Sweden. This is a description that hardly anyone would use to portray the park today. The aim of this study is therefore to investigate what the park once looked like and how it has changed until today?s neglected state. The history of the place and by who and for whom the park with; 4 ½ acers with meandering paths, caves, an avenue, leaf halls and bowers, was created. Who designed the park in the year of 1843 is an unrequited question.

An analysis of Zolas Nana focusing on male desire. Through a study of the narrtive structure and the polemic relation between the concepts of ?Nature? and ?Culture? it is shown that opposing ideologies are imbedded in the text. Nana is a symbolic character, in large, a myth created by male desire that eventually becomes a manifestation of that desire. At the same time, however, the character Nana evolves from being a mirrored image of male desire into a more stable and real individual and this process is also an answer to when and why she dies,underlining the fact that she initially was a creation emanating from male desire and in losing those symbolic functions she loses her function in the novel..

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.
