Islastens inverkan på brottsannolikheten för glidning och stjälpning av betongdammar
There are many old dams in Sweden and, since few dams are constructed today, the main task in risk assessment on the existing dams is often to reduce the risk of failure. RIDAS (Swedish Guidelines on Dam Safety) is used when designing new dams and assess the existing ones. The guidelines include stability requirements for different failure modes, e.g. overturning and sliding, which imply that the load effect from e.g. uplift and ice load need to be less than the resisting loads or moments.
Utveckling av ett svensk-engelskt lexikon inom tåg- och transportdomänen
This paper describes the process of building a machine translation lexicon for use in the train and transport domain with the machine translation system MATS. The lexicon will consist of a Swedish part, an English part and links between them and is derived from a Tradostranslation memory which is split into a training(90%) part and a testing(10%) part. The task is carried out mainly by using existing word linking software and recycling previous machine translation lexicons from other domains. In order to do this, a method is developed where focus lies on automation by means of both existing and self developed software, in combination with manual interaction. The domain specific lexicon is then extended with a domain neutral core lexicon and a less domain neutral general lexicon.
Ljudlandskapets Attribut: Metoder för att bättre förstå och beskriva ljudlandskap
In soundscape research, the field?s methods can be employed in combination with approaches involving sound quality attributes in order to create a deeper understanding of sound images and soundscapes and how these may be described and designed. The integration of four methods are outlined, two from the soundscape domain and two from the sound engineering domain. This study has shown that by combining these methods the understanding of both the entire soundscape and the specific sounds increase. The study also shows that when the methods are used, there is a qualitative change of the description and understanding of soundscapes and the concrete description becomes more elaborate..
Tillämpad informationsteknologi i klassrummet
This bachelor thesis in science Informatics contains the qualifications for the applying of IT in education for students in elementary school, grade 1-3. By empirical case study on an existing elementary school, whose success on IT use is noticed, describes how to apply IT in the classroom in an adequate way. We look at different theoretical frameworks in interaction and design of systems designed for learning purposes, and satisfies their specific needs and situations within the classroom's four walls. The current lack of statistical measurements on students' results and effects of the use of IT in teaching, prevents further improvements. If we simultaneously work to develop more well-designed systems that are designed for this purpose, it is possible that the effects become more and better.
Inventering av trädbränsleaskor : en sammanställning av spridningsbar aska i södra Sverige
I takt med ökande intresse för uttag av grot så ökar också intresset för återföring av aska tillbaka till skogen. I rapporten utreds hur mycket återföringsbar aska som produceras av förbränningsanläggningar. Arbetet begränsas genom att endast förbränningsanläggningar med större kapacitet än 10 GWh träbränsle per år tas med . Dessutom sker en avgränsning geografiskt till att endast ta med anläggningar placerade söder om en tänkt linje mellan Karlstad och Stockholm.Datainsamlingen för förbränningsanläggningarnas askmängder har gjorts både med telefonintervju och enkätundersökning. Totalt har 107 förbränningsanläggningar tillfrågat.
There is no there, there : om platslöshet i fysisk planering
The vizualisation and creating of places is an essential part of physical planning. The notion of places as placeless, is likewise of importance for the creating of places. Some tendencies concerning architecture like modernism, as well as constructions whome don´t fit in their landscape, have contributed to the benaming and experience of places as placeless. Phenomenon as globalization and post-industrialism have in some cases conduced to the withering of the sense of place. With starting-point in litteraturestudies, observations of places and interviews, this is a lucubration concerning the means of placelessness in physical planning.
Ett tidigt möte med matematik : En förskolas arbete med matematik
This research is about the experience educationalists have of children encountering mathematics in a preschool. What is the impact of introducing mathematics in preschool? How do educationalists work with mathematics and how do they experience the children?s interest in mathematics? The aim of this degree project is to examine how educationalists experience children´s interest in mathematics when they encounter mathematics at an early age. The degree project is limited to educationalists and children within a preschool located north of Stockholm.This research seeks answers to the following questions at issue. Does an early encounter with mathematics in preschool lead to increased interest in mathematics among children? How can educationalists in preschool work in a appropriate way with mathematics to stimulate children to develop within mathematics and to increase their interest? How does educationalists in preschool experience children´s interest in mathematics?Theories by Piaget, Vygotskij and Dewey were used as well as former research in this subject.To answer the aim and the questions at issue in this research, three interviews was conducted with educationalists at the preschool and recorded with a Dictaphone.
Betyg och identitet : En undersökning av elevers föreställningar om betyg
A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.
CSR i sociala medier - Möjligheter och risker med att kommunicera CSR i sociala medier
This B.Sc. Thesis examines how Swedish Large Cap companies communicate CSR in social media. We describe the current state of CSR communication in four different social media channels, Twitter, Youtube, Facebook, and blogs. This research, supported by interviews with stakeholders and a quantitative survey, analyses the potential risks and benefits from communicating CSR via social media and provides concrete advice on the development of a CSR communication strategy for social media. Although some benefits have been realized, many companies have failed to truly reap the potential benefits from an effective social media strategy for CSR.
Ta på era "hållbar utvecklingsglasögon"! : Ett idéhäfte som kan hjälpa pedagoger att arbeta mer med hållbar utveckling i förskolan
Natural and environmental issues are everyday parts in preschool but when educators shall consciously work with sustainable development they tend to stop at recycling and what is necessary to be done for achieving the Grön Flagg-certification. I have been observing various preschools and noticed that sustainable development is flawed, often because of the teachers lack of interest, knowledge and in some cases both. Out of this grew an idea of making a project that could help the teachers see how the work with the subject in a fun and educational way can become a part of the preschools everyday routine. I made a tutorial booklet with basic facts and activities relating to sustainable development and the three questions in my report were how much knowledge and interest the teachers initially have, if the tutorial booklet could help the teachers to produce new knowledge and interest for the topic and if it turned out to be easier for them to provide educational activities within the subject. There were three departments that participated in my survey and the methodology of collecting data was an anonymous survey with the teachers' own comments in response.
Moraliska normer och information : En ekonomisk analys av källsortering i Linköping
Den svenska lagstiftningen lägger en stor del av ansvaret och kostnaderna för källsortering på hushållen trots att det inte finns några formella tvång. Den här uppsatsen bygger på en enkätundersökning som utförts på hushåll i Linköping och undersöker varför många hushåll frivilligt källsorterar och bidrar till den kollektiva nyttan miljön. Detta analyseras först utifrån individens ansvarskänsla för miljön, där syftet är att undersöka om detta kan fungera som en förklarande faktor till att individer källsorterar. För att få in ytterligare ett perspektiv på analysen beaktas även individens uppfattning om att han gör nytta när han källsortera, genom ett experiment där respondenterna får ta ställning till hur han förhåller sig till källsortering efter ny kritisk information.Respondenternas uppfattning om att källsortering är miljövänligt verkar ha betydelse för deras motivation till att källsortera. Vidare kan ansvarskänslan och vilken information respondenterna har tillgång till mycket väl vara viktiga faktorer för deras källsortering, även om detta inte med säkerhet går att visa i undersökningen..
Grundskolans nya kursplan för matematik : en jämförande analys av den nu rådande och den kommande kursplanen för matematik
The purpose of this study has been to compare the present with the future syllabus of mathematics. With a text analytical approach has questions about how the structure is different, how the look at knowledge has changed and which learning theory that characterizes the two syllabus been answered. As a theoretical framework I adopt three different learning theories, behaviourism, cognitivism and the socio-cultural perspective. The pervious research I have looked at is the concept of knowledge an the underlying theories to previous curriculum. During the increase results in the greatest difference seen in the structure.

Material- och energiåtervinning av kuvert : Scenarioanalys
Material- och energiåtervinning är två sätt att ta hand om avfall. Materialåtervinning av papper är generellt det sätt som ger upphov till lägst ackumulerade utsläpp av koldioxid. Kuvert är en pappersprodukt som idag saknar producentansvar och branschen för returpapper anser inte att kuvert skall materialåtervinnas i och med att kuvert innehåller substanser som kan ge upphov till stickies. Ett argument som används mot materialåtervinning av kuvert är att problem orsakade av stickies medför ökade kostnader för företagen som tillverkar papper från returpapper. På den svenska marknaden finns det kuvert som, när de processeras i pappersbruken, inte ger upphov till stickies, nämligen svanenmärkta kuvert.
Metaforen - sportkrönikans byggsten : En kvalitativ studie av hur metaforer användes i Aftonbladets sportkrönikor under en tvåmånadersperiod under 2014
The purpose of this study was to study how metaphors are used in sports chronicles . As a complement, we also chose to study whether there are gender differences in the use of metaphors. We also wanted to take a look at whether journalists tend to mythologize sports stars with the help of metaphors. We have been using a qualitative study in our work. We chose to examine four sports journalists who writes sports chronicles for the newspaper Aftonbladet.
