The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.

Kosmologiska gammautbrott är bland de mest energirika fenomen som observerats i universum. Ursprunget för dessa kraftiga blixtar av gammastrålning är idag relativt okänt, men tros komma ur kollisionereller kollapser av tunga stjärnor.  Efter analys av data från detektorerna ombord på Fermi Gamma Ray Space Telescope visas  i detta arbete att spektrumet från GRB 080916C beskrivs väl av den enkla Bandfunktionen (två sammanlänkade potensfunktioner) och därför troligtvis kommer från en enkel strålningsprocess. Den starkaste kandidaten är synkotonstrålning, även om modellen idag inte till fullo kan förklara spektrumet på ett tillfredsställande sätt. GRB 080916C:s isotropa energi mäts till den extremt höga nivån ~ 9 x 10 (upphöjt till 54) erg. vilket är bland de högsta  som uppmätts för gammautbrott..

To be examined in hospitals can sometimes be perceived aspainful by children. Therefore there is a need for something,which can distract children?s attention from their perceivedpain. During my graduation project, I discovered a designopportunity to work with suspended ceiling systems inexamination rooms, as there is not much to look at whilebeing examined.The result, Twig Ceiling is an interactive nature-inspiredbacklit module with colored LEDs. Twig Ceiling has onelayer of pattern that is visible when the module is not litand the second layer of pattern appears when turning onthe light.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

The purpose of this study is to understand school counselors knowledge and work with cyber bullying among students. Our study is based on the result from eight qualitative semi-structured interviews. These interviews were conducted with school counselors working at elementary and high school in the state of Kronoberg, Sweden. Our theoretical base is human services organizations, street level bureaucrats and acting space. Our study shows that school counselors have adopted cyber bullying in various ways which has an impact on their knowledge and systematical work regarding this question.

This thesis is a study of residential environments and a design concept for a proposed housing area in Tierp. The industrial era created a need for the central planning of housing. The confined environments that arised in cities during the 19th century, together with modernistic and democratic ideas, led to regulations in planning and housing. Though the overall goal has been the same: to create a good standard in living, the ideas of how to achieve that have varied. The starting point for following generations has been to attend to the insufficiencies of the earlier planning periods.

AbstractMy purpose of this essay was to discover three- and four-year-olds comprehension of their internal body and then compare the result between their ages. I have used the same methods in both essays, semi-qualitative interviews. It is structured interviews with space for following questions. My formulations of the questions were: Do the children have a comprehension of their internal structure of the body? Do the children have a comprehension of organs and organ systems? Is there any difference between the ages?Their comprehensions I have categorized in four categories and I have seen age related differences in their comprehensions.

This essay concerns graffiti, and in particular graffiti removal regarded as iconoclasm.Graffiti is described as a visual symbol laden with both negative and positive values, and sometimes as a meaningful expression in the urban public space. One problem with graffiti as a field of study is the diversity of both the meaning of the term as well as the diversity of the phenomenon itself. Therefore I have defined the term graffiti as follows: words and images painted on public walls by a person usually in an unauthorised manner. Specific examples of graffiti and related phenomena are presented. Within the Swedish anti-graffiti discourse the pejorative term klotter (scribbling) is used to describe what I above define as graffiti.

Denna uppsats syftar till att, utifrån en granskning av tre olikt gestaltade gator i Stockholm, belysa faktorer och förhållanden vilka gynnar eller missgynnar vistelse och därigenom påverkar möjlighet för möten och interaktion mellan människor. Vi ämnar visa hur Stockholms stad arbetar med sociala aspekter knutna till gator inom planering och gestaltning samt om det finns verktyg för utvärdering av sociala kvaliteter.Genom fallstudier av Sergelgatan, Götgatan och Hammarby allé erhölls resultat om respektive gatas förutsättningar för vistelse. Utifrån litteraturstudier av Jan Gehls och Jane Jacobs mest erkända böcker samt av Stockholms stads styrdokument vid planering och gestaltning av staden, analyserades observationerna av gatorna.Resultaten i studien bekräftar för det mesta Gehls och Jacobs teorier om hur offentliga rum bör gestaltas, med undantag från vissa upptäckter. Ett annat erhållet resultat är att Stockholms stads arbetsdokument inte är tillräckliga för att genomföra en detaljutformning av stadens gaturum. Dokumenten behandlar oftast en mer översiktlig planering och beskriver snarare ett synsätt än fungerar som konkreta hjälpmedel för planerare och arkitekter vid utformning av staden.En mångfald måste finnas i staden för att många kontakter, både ytliga och mer intensiva, ska uppstå och ge staden ett socialt liv.

Humanity has always dreamed about a better world. These dreams has manifested themselves in the vision of Utopia - the good place, but also the non-existing place. Up until World War II man still wrote optimistic descriptions of this ideal world, and spread the idea through literature. In the aftermath of the atomic bomb and under the influence of the cold war, these publications seized to surface in literary surroundings. Despite this utopia did not die - it has only changed.

Stadsdelen Skäggetorp är en förort cirka 4 kilometer från Linköpings centrum som uppfördes under miljonprogrammet det vill säga mellan 1965-74. Under dessa tio år uppfördes drygt en miljon bostäder i Sverige med avsikten att bygga bort den bostadsbrist och trångboddhet som då rådde. Efteråt har byggandet och stadsdelarna från epoken kommit att kritiserats hårt för att bland annat ha monotona och torftiga miljöer. Utemiljöerna var något som allt som oftast blev eftersatt vid byggandet på grund av att det rationaliserades och serietillverkning skedde. Förorterna från miljonprogrammet har även kritiserats på grund av den segregering som allt som oftast skett i dessa stadsdelar.

Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..

The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure. The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.
