Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?
This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..
Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker
The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines.
This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments.
The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done.
The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..
Folkbibliotekets uppdrag i teori och praktik. En diskursanalys kring formulerandet av folkbibliotekets uppdrag i ett urval biblioteksrelaterade tidskrifter under åren 1999-2000
The aim of this Masters thesis is to examine and analyse how the public librarys mission is interpreted and formulated in a selection of library related journals. The journals are both international scientific referee journals from the LIS field and journals with a closer connection to the practitioners within the public library field. The idea is that these journals can be seen as windows to an academic theoretic perspective on public libraries, as well as to the practitioners way of talking about the librarys mission. The study also aims to examine if there is a difference in the way that the librarys mission is interpreted and discussed among theorists and among practitioners within the field. The theoretical starting-point is Ernesto Laclaus and Chantal Mouffes discourse theory, and the method is text analytic.
Vad är Mångfald? : En studie om lärare samt ledning i två skolor i olika delar i
The subject of this paper is to examine the view of diversity among ten teachers and three principals in the Swedish compulsory school. The purpose is to investigate how they relate to the diversity and in what ways it is involved in their work.The French sociologist Pierre Bourdieus basic ideas of habitus, capital and field are used as a theoretical starting point. The study is mainly based on interviews supported by literature in the subject area.The findings show that diversity is associated with ethnicity among all informants. The drawn conclusion is that this is partly due to the mediated picture but also since ethnicity mainly serves as a starting point in the literature..
Sönderdelning av plogtilta med skärknivar :
During the last couple of years it has been more important to reduce the driving on the field to prepair the soil after ploughing. The machine costs are high so it is necessary to be effective. To reach a pleasant soilbed directly after ploughing is sometimes possible on easier soils but heavier clay soils always need more tillages. There is a lot of equipment mounted on the ploughs on the market, for example Furrow Cracker and Furrow presses, which makes a pleasant soilbed on easier soils. The last year Överum and Kverneland have presented knives which are mounted on the wing or moulboard.
Konst Kräver Offer : En analys av Nathalia Edenmonts konstnärskap i ljuset av Pierre Bourdieus kulturteori
Nathalia Edenmont is a controversial and uncompromising photo artist who has caused the whole world to rage over her obscene photographs. In this thesis I have researched Edenmonts artistry with help of the sociologist Pierre Bourdieus field analysis. By using Bourdieus's different field concepts I have researched Edenmonts artistic career by concepts such as habitus, consecration and different principles.The starting point of this research has been that Nathalia Edenmont is in the autonomous artistic field. I give examples of images that have been highly debated and I have collected information of how Edenmont sees her own images and her artistry. In this thesis I show amongst other things an example with Edenmonts photograph of dead rabbits with Elizabethan hair styling, cut up mice that work like finger puppets and children who are bound up in wire.Nathalia Edenmont autonomous artistry is deeply rooted in her background and the environment in which she was raised.
Evaluation of transgenic lines of field pepperweed (Lepidium campestre L.)
The worldwide industrial demand of energy, often in form of fossil fuel, is continuously growing and at the same time these resources are coming to an end (Hamamre, 2013). The interest and focus in renewable sources are then more important than ever and plants are suggested to be a good
alternative for production of raw material for industrial purposes (Nilsson et al., 1998). But the world is also facing an increasing world population which also increase the nutritional needs, plants therefore need to be suitable for both industrial and nutritional purposes. To achieve this, common plants need to be improved but it also need new potential crops to be developed and introduced
(Carlsson et al., 2009). Modern technology like gene engineering is an important tool to achieve these challenges (Carlsson et al., 2011).
This work focused on analyzes and evaluation of different transgenic lines of field pepperweed (Lepidium campestre L.).
Pressning och hantering av halm som energiråvara
I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.
Damaged Goods : Med fokus på emotionell kommunikation
How can the object based art help us, as viewers and as makers, to access a supplanted emotional state?One way of positioning yourself within the corpus-field is to step outside the traditional borders of the field and aim for other values within the objects, such as a visible working process, a storytelling or an emotional relationship to the object. It is a way of taking a step from the traditional silversmithing towards some kind of free undefined corpus-art. To reach for suppressed feelings is one way to find an importance within the artistic work, to give it a purpose.By investigating the concept of the sublime and the surrealist movement I try to find examples on how you, both as a viewer and as a maker, can put yourself in an emotional/intuitive state. Through interviews with Jewellery and corpus artists I get a maker?s perspective which I compare with my own reactions to their work.Works of art can be used as a catalyst to reach, and maybe also to process, unattended feelings. This creates a strong emotional connection to the work. As a maker you can, for example, do this by working with it as a theme, or by using an intuitive working method.
Säkerhet till varje pris : En jämförande studie om utvecklingen av privat säkerhet från Kuwaitkriget till Irakkriget
The purpose of this essay is to examine the development of the use of private securitycontractors in Iraq. The reason is that there has been a considerable increase of the number ofprivate security firms operating in Iraq during the last couple of years. The legislation in thefield of private military and security is indistinct and my hypothesis is that the lack of nationaland/or international legislation can be connected to the increased globalization. To come toany conclusions about this I have chosen to make a comparative study between the two casesthe Gulf War and the War in Iraq which started in 2003. In this comparison, I ask thefollowing questions: 1) Are there any signs of anarchy in the field of private security duringthe Gulf War respectively the last War in Iraq? 2) In what way has the use of private securitycontractors changed from Case 1 to Case 2 ?According to my research, there were signs of anarchy in the field of private security bothduring the Gulf War and during the latest war in Iraq.
Kvotering i Polishögskolan : En rättslig studie rörande tillåtelse att kvotera vid antagning till högskola och huruvida kvotering förekommer i polisutbildningen
The purpose of this essay is primarily to investigate the possibility of and the rules concerning using quotas in the field of admission to university. Secondly, an investigation of whether the Swedish Police Academy has been conducting this method during the years of 2009 and 2010 is made. They are currently accused of having discriminated applicants due to their gender and ethnicity. In order to examine the legal arena as far as possible the laws of discrimination, both including the legislations and regulations assumed by the EU as well as the Swedish laws in this field, will be studied. The laws of discrimination will be put in relation to the legal possibilities of making exceptions from the principle of equal treatment.
Minoritetspolitik för vem?
Different reports imply that the Roma are an excluded group in numerous areas of both Sweden and Europe. Efforts have been done through the centuries without given intentional results. The past 12 years as a Swedish national minority have not diminished the gap between the Roma and the majority society. How does Sweden create and operate its minority policy especially towards the Roma? We have studied international and national minority policy to see how it is described and implemented in the municipality work.
Med sinne för detaljer : En domänanalytisk studie av ämnet Textilvetenskap vid Uppsala universitet med fokus på föremålsdokumentation
The aim of this two year master thesis is to study the knowledge production within the field of Textile Studies at Uppsala University, with special focus on the use of artifact documentation as a research method. With domain analysis as a theoretical framework, ontological and epistemological assumptions as well as historical and social aspects are studied in relation to the research process. Qualitative research methods are used, including interviews, observations and text analysis. In the analysis of the knowledge processes in the field, perspectives on tacit knowledge and the concept of documents, are used as a theoretical basis. In the field of Textile Studies, the artifacts are used as one of the main objects of study, along with archival and pictorial sources. The main epistemological assumptions are that artifact analysis is dependent on a knowledge base, where technical handicraft skills, contextual knowledge and practical experience of object observation are the most important qualifications.
Utvärdering av Field-Programmable Gate Array (FPGA) som hjälpprocessor för prestandaökning
Det här arbetet är en utvärdering om huruvida det finns problem som kan få en prestandavinst då man använder en Field-Programmable Gate Array (FPGA) som hjälpprocessor till en mikroprocessor i jämförelse men att enbart använda en mikro-processor. För att avgöra detta implementerades algoritmen gaussfiltrering dels på en mikroprocessor med språket C och dels för en FPGA med hårdvarubeskrivningsspråket Very-High-Speed Integrated Circuits Hardware Description Language (VHDL). Simuleringar gjordes för dessa två implementationer och resultatet visade att det var möjligt att få en prestandaökning på 25 gånger för denna speciella algoritm..
Ett tydligare System C2 : Användargränssnittsutveckling med stöd av användarcentrerade metoder
User friendly and usable are two words that are often mentioned in the context of marketing new products. By doing so it adds an extra sense of quality to the product. The meaning of these words is therefore something that every product wants. But what is it that makes a product usable and user friendly? What methodology exists formaking sure that a product is usable? Does it exist applicable processes to ensure user centered development? These questions together with a practical example are parts of what will be addressed in this report.The thesis was carried out for C2 Management, a company that works with supporting other companies in their work with quality and constant improvements.
