Sammanvägda avrinningskoefficienter i rationella metoden : en jämförelse mellan idag och 1970-talet

Storm water is rain and melted snow that runs off, primarily from impervious surfaces.Future storm water management is facing the challenges of increased precipitation, asclimate changes, and increased areas of impervious surfaces due to the expansion anddensification of the cities. Impervious surfaces reduce the potential for water to infiltratein the ground leading to increased surface runoff and higher peak discharge.The runoff coefficient is closely related to the percentage of impervious surfaces andrepresents the maximum percentage of a catchment that can contribute to runoff. In thisstudy, the objective was to evaluate the weighted runoff coefficient for three differenturban types; apartment buildings, townhouses and residential areas and a comparisonbetween today and the 1970`s was made.The runoff coefficient was determined by manual mapping of the different surface typesin each area based on data in the form of orthophotos and aerial photographs. The surfacetypes that were mapped were asphalt, permeable areas, tiles, sand/gravel and roof.Tiles and sand/gravel were the most difficult surface types to map. In order to see towhat extent these categories influenced the weighted runoff coefficient a sensitivityanalysis was carried out and the runoff coefficient based on surface type was changed indifferent scenarios.The results of the Sensitivity analysis showed that the surface types tiles and sand/gravelhad little impact on the weighted runoff coefficient which in mainly due to the fact thatthe percentage of these surfaces types of the total area is small.The result of the study showed that the largest change in the runoff coefficient occurredin residential areas where the increase in the percentage of impervious surfaces causedby new roofs in the form of porches and garages and from paved or tiled driveways.

Betydelsen av förändringar i DuPont-komponenterna för framtida operativ lönsamhet

The DuPont formula is one of the most well known and basic tools used for financial statement analysis and is highly useful for understanding firms strategies and operating environment. Previous studies on American listed companies have also shown that analysis of the changes in the DuPont components is useful in forecasting contexts. In this thesis we test whether disaggregating the change in return on net operating assets provides incremental information about future performance for Swedish listed and not listed companies. We find that the change in asset turnover is a leading indicator of increased profitability for both listed and private companies, regardless of size. We also find evidence that the usefulness of the disaggregation for understanding future performance is greater in capital intense industries and lesser in service industries..

The Picture book - text and image in interaction. A study of Tove Jansson's picturebook: The Book About Moomin, Mymble and Little MyThis study examines Tove Jansson's picture book The Book About Moomin, Mymbleand Little My, to show relationships between text and image in the narration of thestory.

The various concepts are; the epicpicture book, the expanding text as well as the genuine picture book. This study hasperformed a text and image analysis showing that the image colors, the differentspreads, landscape scenes and characters' placement, et cetera play a role in placingthe picture book in its concept.Tove Jansson used more than text and image to work out the story of theMoomintroll, Mymble and Little My, there are holes in the picture book that have animportant role, which the analysis will show.

Att klassificera arkeologi: En komparativ studie av tre klassifikationssystem

The purpose of this Masters thesis is to compare classification codes and feature headings of three different universal classification schemes SAB, UDC and DDC, when classifying archaeological literature. The aim is to determine whether a subject analysis of a title generates similar feature headings in the three systems, and to find positive and negative things about each system from an archaeological point of view. The comparison and the analysis of the 22 chosen archaeological monographs showed that the subject analysis of the titles didnt always generate similar feature headings. This could depend on several things, for example different interpretations of the subject analysis of a document, less knowledge about the system and/or the subject, or the fact that its not the same classifier that creates the codes. The study also showed that the different classification systems did treat the subject archaeology a bit differently, and that its difficult to say that one of them is better for classifying archaeological literature.

Biografier om gangsters och åldrande rockstjärnor som snortar myror : en diskursanalytisk undersökning av litteraturförmedling i livsstilsmagasin för män

 The aim of this thesis is to examine men's attitudes towards literature, and how social norms affect their book reading, in order to contribute to the knowledge of why men's book reading is decreasing. This is realized through a discourse analysis of literature recommendations in men's lifestyle magazines.Two magazines, King of Sweden and Magazine Café, are examined through critical discourse analysis. Theories of discourse are combined with theories of gender to explore how gender stereotypes affect men's reading habits.The analysis shows that ideals of masculinity have a great influence on the book recommendations. Social norms, associated with gender, also seem to have significance to whether or not a book is considered suitable for men to read. These are, inter alia, norms of heterosexuality and violence.

Valda verkligheter : En studie av svenska och engelska tidningars konstruerande av verklighet i rapporteringen kring Julian Assange

This is an analysis of how the Swedish newspapers Dagens Nyheter and Aftonbladet and the English newspapers The Independent and The Guardian reported about the sexual molestation and rape charges that were alleged against the Wikileaks founder Julian Assange in August 2010. Through a critical discourse analysis, a theme- and proposition analysis and a process analysis this paper aims to investigate how the above mentioned newspapers create reality in their articles. The purpose is to shed light upon with what means the journalists through the inherited structures of the newspaper illustrate actions and events, how they let other people get visible in the text and who is described as responsible for current events.    The results of the analysis shows that Aftonbladet uses a relatively large amount of propositions and speech cues to create an image of the reality that is almost explicitly angled. Dagens Nyheter and The Independent claims a higher degree of objectivity and through micro themes with different perspectives and few explicit statements they create a reality with plenty of room for the reader to make her own conclusions. The Guardian creates an image of the world where the Wikileaks is a great force of democracy and where actions are performed by humans as well as by objects and organizations.   .

Hur ska tall- och gran bestånd i Götaland gallras för att minska risken för vindskador?

With knowledge of how the southern Swedish forests have been affected by storms the past years, this study intended to find out which factors affect the storm firmness of a stand the most. The study was based on data from stands in the, by the storm Gudrun, affected area. The results of the analyses that tested the stand factors that influence the amount of storm damage to the greatest extent showed that the storm sensitivity of Norway spruce stands were largely due to previous management actions. The factors that could be controlled by thinning and had relevance of storm damage standpoint, according to the results were; the dominant height, volume, basal area weighted mean diameter and stand age at last thinning. In this study, these results are not as clear for Scots pine.
