Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

The aim of my study is to answer the question whether there is a potential for services by working horses in the Swedish municipalities. The Swedish University for Agricultural Sciences (SLU) and Swedish Farmers Union (LRF) has started a cooperation called Climate School (Klimatskolan), with the purpose to increase knowledge in environmental and climate related issues in context of agriculture. This Master thesis is in the framework of the Climate School.Global warming is a problem that gets much attention today. Global warming and climate change are two subjects that are very much in focus on the political agenda. The municipalities of Sweden have a big responsibility concerning environmental work and to develop their own environmental thinking.

The aim of this study was to describe and analyze if and in that case how project Speaking English contributes to improved skills in English to pupils in reading and writing difficulties. The project started out in order to give pupils in reading and writing difficulties an alternative to the regular English teaching. The study was carried out in two nine-year compulsory schools. We have conducted interviews with both teachers and pupils to see what they think about the project. According to the teachers we interviewed Speaking English contribute to improved skills for the pupils and they also believe that their chances to pass the 9th grade will increase.

A literature study and a field trial have been carried out in order to investigate the physiological response of potato plants to different soil moisture levels. Higher yield, quality and number of tubers can according to the literature be obtained if constant high soil moisture is kept during major parts of the growing season. A field trial was set up where drip irrigation was used as an alternative to conventional irrigation techniques to maintain high and constant soil moisture. The application of water in the drip irrigated area was monitored and adjusted on a daily basis so that the soil moisture stayed as close as possible to the recommended level. The sprinkle irrigated area was irrigated according to traditional practices with approximately 35 mm every 7th to 10th day depending on the whether.

The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

Hus byggs idag allt tätare för att möta högre miljökrav, ställda av både konsumenter och politiker. När hus byggs täta minskar luftläckaget genom klimatskalet. Tack vare det sänks energiåtgången då nästan all luft styrs genom en värmeväxlare. Tätheten i de nya husen har lett till att utsugande köksfläktar inte fungerar som de ska, beroende på att de behöver mycket luft. I detta projekt utvecklades ett utsugande köksfläktsystem för passivhus, de allra tätaste husen på marknaden.

In the 1970s and 1980s, Sweden held about 15-20 certified health resorts that wanted to improve peoples? health with vegetarian food and alternative medicine. This essay aims to explore the popularity of health resorts through a patient?s perspective. What did the patients look for at the resort, which they could not find in the official health care? A basis for the analysis is Bonnie Blair O´Connor?s theory of Health Belief Systems.

The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

Sweden has had laws protecting nature for about a hundred years. In this paper the views of nature and the values that serve as a rationale for protective measures are analyzed as results of a social process characterized by the dialectic relationship between institutions and discourse. Critical discourse analysis (CDA) is used to study this relationship and the discursive practices used by institutions, which reproduce or reshape views of nature that define the relationship between society and nature. Institutional design contributes to shaping discourse in the field of nature protection, while being originally shaped by discourse. In Sweden, the national park is an institution that reproduces a view of nature as the wild and untamed opposite of society, and the natural reserves reproduce a view of nature as holder of a multi-faceted set of values intertwined with society.

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.

Med anledning av den debatt som förts i media om svaveldirektivets införande blev vi intresserade av attsammanställa olika instanser syn på direktivet samt hur deras intentioner förhåller sig till varandra. Med detta som utgångspunkt utvidgade vi arbetet till att studera flera typer av styrmedel. I resultatet har vi presenterat en sammanställning av intervjuer vi utfört med svenska politiker, hamnar och befraktare. Vi kom fram till att svaveldirektivet behövs för att åstadkomma en reducering av sjöfartens utsläpp av miljögifter men att direktivet inte kommer kunna uppfyllas av alla fartyg på grund av brist på lågsvavelhaltigt bränsle, stora hinder för LNG drift och tekniska problem med skrubbers. Skatt på marina bränslen och utsläppsrätter för sjöfarten som styrmedel bedömdes inte vara aktuellt inom en överskådlig framtid.

Arbetets syfte var att undersöka intentionen och förväntade effekter av den nyasjöarbetskonventionen som nu ska implementeras vad gäller bemanningsnivåer ochvilotider på svenska fartyg. Genom att först genomföra en litteraturstudie lades grundenför arbetet. Med anledning av att konventionen inte var implementerad genomfördes enkvalitativ intervjustudie mot tre sakkunniga representanter från svensk sjöfartsnäring föratt utreda vad konventionens verkliga intention var. Därefter genomfördes en kvalitativintervjustudie mot fyra aktörer i den svenska sjöfartsnäringen för att utreda vad dessaförväntade sig för effekter av konventionen, gällande bemanningsnivåer och vilotider.Resultatet av undersökningarna visade på att konventionens intention är att höja deninternationella standarden vad gäller just bemanningsnivåer och vilotider till en nivåsom liknar den svenska relativt höga nivån. Vad gäller förväntade effekter avkonventionen tror de svenska aktörerna att den svenska sjöfartsbranschen kommer att seganska små förändringar om några alls..

Syftet med detta arbete var att ta reda på hur många studenter i avgångsklasserna vid Sjöfartshögskolan som fick en anställning via Career Event 2012 och studenternas uppfattningar om mässans funktion som en plattform för yrkesmässiga kontakter med företagen inför framtiden. I sökandet efter tidigare arbeten hittades ingen liknande undersökning. Däremot hittades ett arbete som under rekryteringsmässorna Career Event och Sjölog 2011, undersökte rederiernas framtida behov av arbetskraft. Arbetet Career Event ? Jobb i sikte försöker komplettera den bilden genom att här presentera hur det faktiska utfallet blev året 2012.

Libraries exist around us and for most of us they are a part of our every day life. But how often do we stop and think about their meaning?Libraries in fiction are usually not the center of the narrative, they play a role quietly in the background and offer a backcloth to the story. Yet they are a vital part of the story. Without them a big part of the magic in the stories would be lost.And what is their role in our lives? What do the libraries mean to the books they harbor, the readers who seek them out and society in which they have their axiomatic role?This essay?s focus is my story ?Between the shelves?, which is about the young girl Julia and the mysterious passageway she discovers in her local library.
