Potential för värmeåtervinning från mjölkkylanläggningar

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

Matematiska färdigheter hos elever med lässvårigheter i årskurs 4

Reading difficulties is the most common learning difficulty in the western world and it is common that people with reading disabilities also exhibit arithmetic difficulties. Different theories about the cause of the relationship exists, one theory describes the importance of good phonological ability in reading as well as in arithmetic, while another theory describes the importance of a reliable number system and that only a subgroup of students with reading disabilities also have difficulties with arithmetic. The purpose of this study is to investigate how students with reading difficulties (RD), without any known mathematical difficulties, perform on mathematical tasks relative to a control group. The study was theoretically grounded on the Triple code model (Dehaene, 1992), which is a model for numerical information processing that describes how various numerical and arithmetic tasks are processed through three distinct representation systems in the brain, a verbal and a visual representation system and a quantity system. Reading skills, phonological skills, arithmetic skills and number processing skills were examined in 61 students through a variety of tests.

Där jag aldrig varit

The sites I visit turned into routines a long time ago. Everywhere someone has decided what should be there and what will not fit. I retreat into my daydreams, away from everyday life. A longing for something different, something wonderful. I decided to go where I've never been, searching for something unknown.

Framtagning av förbättringsförslag för SNCR-system

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Alla elever har särskilda behov : En kvalitativ studie med fokus på lärares upplevelser av att motivera elever med hög potential

Alla elever i dagens skola, oberoende av inlärningskapacitet, skall ges likvärdiga möjligheter till progressivitet av befintliga kunskaper i det egna lärandet. Iakttagelser under bland annat VFU indikerade en problematik i enskilda lärares förmåga till att förse samtliga elever med kunskapsmässiga utmaningar. En förbigången elevgrupp utgjordes här av klassens snabba inlärare; elever med hög potential. Syftet med undersökningen har varit att ur ett lärarperspektiv, söka reda på fungerande arbetsmetoder för att nå och tillgodose samtliga elevers kunskapsmässiga behov i undervisningen. För att belysa aspekter, specifika ur yrkesverksamma lärares synvinkel, valdes en kvalitativ intervjumetod av semistrukturerad art för undersökningen.

Teknisk undersökning av stafflimåleri ? Med fokus på två dörröverstycken från Röhsska museet

This bachelor thesis is a study in the analysis of paintings with focus on the technical exami-nation within the framework of ATSR. ATSR is a methodology based on an interdisciplinary study with the aim of putting the object in its context.The study is based on questions concerning which information the object can give, how we access this information and how it can be put in a larger context. My thesis contains three major parts. First a short overview of methods of analysis used in this form of investigation is presented. This is followed by two case studies which exemplify the technical investigation.

Flipp eller flopp?: En kvantitativ studie om bloggens potential som marknadsföringsmedium

The blog has become a widely discussed subject, but while marketers do invest in blogs, there is little evidence on the how the blog works as a marketing tool. Therefore, we thought it would be interesting to create a greater understanding of the blog's potential communication effects. To demonstrate the potential of the blog in comparison with more traditional media, we decided to compare the communication effects achieved by a blog with those achieved by an online magazine. We pursued an experiment where we exposed an identical text about a brand to respondents in seven blogs and in seven online papers and measured the resulting communication effects in terms of attitudes and intentions towards the exposed brand. The quantitative study showed that the blog in some basic aspects works as a more traditional media; when the consumer forms positive attitudes toward a text in a blog, the attitude spills over to the attitude toward the brand, with higher buying and w-o-m intentions as a consequence.

En utredning av tekniken "mobile mapping" i kommunal verksamhet

This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.

Tilltal i bild och text : En studie av gymnasieskolors hemsidor ur ett kommunikationsperspektiv

Due to political decisions regarding the Swedish school, public and independent schools booth face the need topromote themselves in the quest for new pupils. This study aims to, from a communications perspective, examine how four selected upper secondary schools address their target audience; the pupils?to?be, on their homepages. Additionally, I intend to investigate whether, and if so, how, said addressing can be connected to the different target groups applying to the schools in question.The questions asked in this study regard the way in which the selected schools describe themselves on their homepage; how do they use the textual and visual content to address their audience, and can there be disagreement between the meaning of the text and that of the image? To answer these questions, I use a theoretical base made out of visual communication and semiotic as well as rhetorical analyses.The methodological procedure is a qualitative approach on the matter, allowing me to understand the ?what? of the content on the homepages, as well as the ?how? it?s being communicated.

Matting of Natural Image Sequences using Bayesian Statistics

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.

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.

Spelmarknadens utveckling och relation till spelproblemen i Sverige 1999-2009 med fokus på män i åldern 18-24 år

The share of problem gamblers increased for men between 18-24 years old during the period 1999-2009, while the share were steady or decreased for other classes of population. This study examines the relation between this development of problem gambling and the Swedish gambling market. The factors that are studied are the functioning of the market with a focus on the new Internet market for gambling, the games and the underlying risk factors in those, the marketing and other factors outside the gambling market. First a large literature review was made to map the development as detailed as possible. After that a qualitative analysis of the content in television commercials was done to see if they were made for the problem group.

Online visual merchandising -ur ett konsumentperspektiv

Denna uppsats handlar om modeföretags online visual merchandising ur ett konsumentperspektiv. Vi har undersökt vad konsumenter anser vara viktiga aspekter ur perspektiven miljö, navigering och produktpresentation för att de ska finna en e-handelssida attraktiv. Tidigare forskning visar att för en kund ska genomföra ett lyckat köp på ett modeföretags e-handelssida krävs det att den virtuella miljön är väl utformad. Dock fann vi ett gap i tidigare forskningen där teorierna inte var prövade utifrån ett konsumentperspektiv. Målet var därför att skapa en modell, som tog hänsyn till konsumentens åsikter, och som modeföretagen kan ha användning för vid utformning av sin virtuella miljö.
