Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.

The aim of this thesis in Archival Science was to explore the concept of electronic archives and the challenges that might be encountered when attempting to move archives into a new digital age, as well as having a closer look at the term e-archive itself. Another aim was to explore how the OAIS reference model works in practice.To explore these questions I decided to do a case study on E-Arkiv Stockholm, a functioning e-archive. I decided to do a study on several documents that were created throughout the project, these included documents related to the planning of the archive, as well as the final report. My reason for this method was that these docu-ments came straight from reality and would give a clear and unbiased view of the project and it?s many aspects.Examination of the documents showed that the OAIS reference model and its concepts had been the foun-dation of much of the planning.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

The aim of this thesis is to investigate what information needs arise from the interest in music, which sources are preferred, how this information is sought and what part does the public library play in providing music materials. Brenda Dervin`s Sense-Making theory is what serves as a theoretic framework for this study. A qualitative approach was undertaken in the investigation and nine interviews were conducted with people interested in music. Findings indicate that different ways of acquiring information are used depending on the situation in which the information is needed and also what kinds of music people prefer. The main findings of this study suggest that people interested in music are keen to constantly discover new music to perform or listen to.

The purpose of this examination is to investigate how Judisk Krönika, a periodical which was introduced in 1932 with the aim of disseminating Jewish culture and tradition in Sweden, uses history to make comments about its role in contemporary history, specifically during the first two years of the First Intifada. A second purpose was to examine how this use of history differed from results shown in earlier studies comprising the 1960s and the 2000s. The method in use is qualitative; the source material has been read thoroughly and scrutinized in search of the authors open and hidden messages and intentions. The main finding shows that four major themes could be identified: anti-Semitism(anti-Zionism); memory; ethnonational and media. The most dominant theme during the 1980s, as opposed to the 1960s and the 2000s focus on Zionism and Jewish culture respectively, is memory, that could be described as hegemonic and as a part of a existential use of history, which aims for survival and preservation of the Jewish culture in times of conflict..

Målet med detta arbete var att belysa skillnaderna mellan ett fyravåningshus med trä- respektive halvprefabricerad betongstomme ur ett tekniskt perspektiv för att utröna vilket stomalternativ som är att föredra.Faktorer som belystes var:Tjocklekar på bärverksdelarLängsta möjliga spännvidderInstallationsmonteringElementmonteringGrundstorlekLjudisolerande förmågaRisk för fuktskadorBranddimensioneringProjekteringskomplexitetBygghandlingar från ett befintligt flerbostadshus med trästomme erhölls och analyserades, och ett hus med likvärdig stomme av betong projekterades.Bärverket med halvprefabricerad betong dimensionerades efter rådande Eurokoder och detaljer utformades enligt gällande lagar och regler samt erkänd branschstandard.Ur de tekniska perspektiv som avhandlats i denna rapport väger fördelarna med betong något tyngre än träalternativets fördelar trots att egenskaperna i vissa hänseenden är mycket lika.Betongalternativet ger stora fördelar vad gäller brand och ljud och är samtidigt enklare att projektera, medan trä har sina fördelar i montering och grundläggning. Att välja en stomme av trä till ett flerbostadshus verkar också ha fördelar i de icke avhandlade aspekterna, t.ex. miljö och arbetsmiljö.För att uppfylla ljud-, brand- och fuktkrav i ett trähus krävs det avancerade byggsystem som innebär stor komplexitet i projekteringen vilket kräver ett nära samarbete mellan träprojektör och fabrikör. .

This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.

In this essay I have tried to present the ideas and thoughts of the Swedish author Rolf Edberg (1912-1997), journalist, ambassador and county governor. By many regarded as an environment philosopher and the introducer of deep ecology into Sweden. The essay emphasizes Edberg as a modern renaissance man of important knowledge with a rhetorical force to present and generalize the problems the planet Earth is meeting. The paper compares him with Henry Thoreau but also finds a close but perhaps unintended relationship with the German philosopher Ernst Haeckel although Edberg himself claimed to be a Darwinist at heart.The essay stresses on four characteristic features in his authorship namely 1) a holistic view of nature and man, rejecting dualism for monism; 2) a cosmic relationship within the whole universe and also between organic and inorganic matter; 3) the planet Earth is in a crisis due to an uneven and unjust distribution of the resources of the Earth, the nuclear weapon threat and the overpopulation; 4) the evolution and not the religion has the answer to our existential questions..

My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.

Uppsatsens undersökningsområde är den världsomspännande idé eller rörelse som går under beteckningen Corporate Social Responsibility (CSR), företags samhälleliga ansvar. En viktig del i CSR-rörelsen är den internationella avtalskonstruktion som benämns Global Compact. Med FN som plattform har ett globalt samarbete mellan företag och intressegrupper upprättats där frågan om företags samhälleliga ansvar behandlas med hjälp av tio principer. Undersökningen har två delsyften; A) att beskriva och undersöka bolags samhälleliga ansvar enligt Global Compact, särskilt enligt principerna 1 och 2, samt B) att kritiskt pröva frågan om det ansvaret är förenligt med bolags legala vinstsyfte. Först följer en deskriptiv redogörelse av CSR och Global Compact för att visa på grunder, struktur och terminologi.

The aim of this study is to describe, from a didactic point of view, wether gender norms are challenged and sex equality is maintained when two teachers in grade one communicate with their pupils. This is based on the existing norms in our society which generates into certain expectations of how one should act depending on wether you are a girl or a boy. In addition to this, the lack of equality between women and men is a global question. The norms and conditions in society are reproduced, but can also be deconstructed in school (Martinsson and Reimers 2008, p. 8).

In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.

The Sitting while waiting for sustainability project goal was to make a functional model for a resting chair and to make it by using furniture and artefacts as material. A try of understanding the process of re-design and to use it to design was driving the project through. The result was a prototype made out of a bed frame and 18 pair of jeans and with details made out of leather..
