Increased resource efficiency in an energy system could result in large economic and environmental benefits. Tekniska verken i Linköping AB (Tekniska verken) is responsible for the district heating network in Linköping. Their vision is to create the world?s most resource efficient region. An important step towards this vision is more efficient usage of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system.

This is an essay concerning the density of the city. An increasing amount of today?s cities have a shortage of space available for the erection of new buildings and settlements, especially in areas close to the city-centre. New buildings and settlements are therefore often found in the outskirts of the city, resulting in long distances between work and living for many people. These long distances are a waste of limited resources and are inconsistent with the vision of the sustainable city.The challenge for the future is to insert new buildings and settlements in the existing city-structure and in this way reduce the distances between different city-functions.The density of the city can be increased in two different ways; by inserting new buildings between existing ones or by extension existing buildings, for example by an additional floor.

Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.

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.

The soil acidification and the pH-value of the soil have been discussed for many years. Many observations of the tree species effects on the soil pH have been done. We have discussed the effects on the soil surface pH-value with a birch (Betula spp. L.) admixture in Norway spruce stands (Picea abies L.).We have used data from the Swedish National Forest Inventory. We have also discussed how the wood production and the biodiversity can be increased in mixed stands, in according to the Swedish forestry act Skogsvårdslagen. Our sampling areas are located in Norrland, Sweden. The results show a significant correlation between an increased birch admixture and an increased pH-value of the soil.

AbstractThe purpose of this essay was to examine how young people who are about to graduate from high school define and value their future. We also wanted to se which emotions they associate with their future and what or who influences them in their choices in life.The questions for our study were:What does it mean for these youths to become an adult?What images do they have of future education, profession and unemployment?What or who influences the picture they have of their future?What kind of attitude do they have towards the future?We approached the research with a qualitative method and interviewed ten youths in high school. Our conclusion was that the youths had an ambivalent attitude towards becoming adults; it was scary and yet exciting. The youths had the impression that education was important in order get a good job and to avoid unemployment.

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.

Inom stadsplaneringen har man förstått vikten av en blandad och varierad stad. Istället för att tänka skola här, bostäder här och jobb där, försöker man nu integrera allt till en helhet. Jag har i detta projekt undersökt vad händer om tänker byggnaden som en stad, som används av olika människor under dygnet, veckan och året. Det är en studie i hur olika verksamheter kan samverka inom en byggnad. Och på så sätt skapa en byggnad som utnyttjas effektiv, används dygnet runt och av olika människor och verksamheter.Projektet tar utgångspunkt i en existerande miljö.

Eskilstuna Folkhögskola is located in Munktellstaden in Eskilstuna. The school has two separate buildings with entrances that are difficult to find. By having two separate buildings, and to be in an area where there are rules and guidelines for the area's environment, makes it difficult to guide visitors to the school premises.The purpose of my research was to examine how to guide visitors to the school, and how to increase understanding that the school's various buildings are connected.Through practices such as site analysis, interviews, I found that the guidelines are not adapted to the current situation that is established in the district.Through theory and empirical material I have produced a design proposal to facilitate Wayfinding to Eskilstuna Folkhögskola. This is presented as a landmark and a clarification of the schools entrances and signage..

This essay tries to show how The Swedish Museum of Architecture, Stockholm, with the exibition Architecture in Sweden - Function, Design and Aesthetic through the Ages, presents and represents architecture. It is stated that this is done in a multi-perspectival, multimedial fashion, with the aid of, for example, photography, models and mixed material surrounding the wide concept of ?architecture?. One chapter discusses the relationships between the exhibition on site, the exhibition catalog and the museum´s website. Another chapter argues that there can be no essential or perfect representation of architecture, although this utopian wish most certainly exists even today.
