ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

The purpose of this study was to examine and increase the knowledge about the way young, newly graduated social workers view their professional role considering their age and professional experience, how they experience the relation to their clients and colleagues and how these experiences all together affect the way the young social workers handle their professional role. Seven social workers in the ages between 23 and 25, who graduated from Socialhögskolan, Stockholm University, in January 2007, where interviewed. They also answered a questionnaire covering the similar questions as the interview. Little research had previously been made in this particular area, why the triangulation of methods was helpful in analyzing the results, with ata coming from two different resources. To analyze the data a multidimensional theory was used, containing coping theory, an experiential perspective, Antonovskys theory a sense of coherence, cognitive theory and role theory.

The aim of this study was to increase the knowledge about if and how the National Value System?s goal of a life with dignity for the elderly pervades the work in home care organisations. The study was based on a qualitative research method and was conducted through interviews with professional care givers in home care organisations, there were five individual interviews and one pair interview. The background for this study was the National Value System for the eldercare that was introduced in 2011. The theory of New Public Management and the concept of Rationality of Caring were used to analyse the result.

Marknaden för mobila system har utvecklats enormt snabbt de senaste åren. Idag är det ett område med en allt större omsättning och det har vuxit fram som en helt ny gren inom Software Engineering. Utvecklare av mobila applikationer står ständigt inför en utmaning när det gäller att välja vilket mobilt system man ska satsa på när man utvecklar applikationer. Valet av system kan vara helt avgörande för om man hittar rätt målgrupp av konsumenter och därmed kan generera tillräckligt med omsättning för att driva lönsam utveckling av applikationer. Det räcker inte att enbart kolla på vilket system som har mest användare eller vilket system som genererar mest omsättning, utan man bör noggrant överväga de förhållande som gäller för just den applikation som ska utvecklas.

To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..

Projektet omfattade en jämförelsestudie avseende stomsystem. Studien undersökte ramverk och fackverk/balk/pelar-system och genomfördes självständigt med stöttning av Ramböll AB´s kontor i Falun. Syftet var främst att undersöka vilka skillnader det finns mellan tvåledsramar och fackverk/balk/pelar-system för lätta hallbyggnader och försöka få klarhet i varför fackverk/balk/pelar-system är det dominerande systemet i Sverige eftersom övriga Europa har tagit en annan utveckling och domineras av tvåledsramar. Studien undersöker skillnaderna mellan systemen i en hallbyggnad med förutbestämda mått i stål.Inledningsvis gjordes en litteraturstudie för att få en bredare bakgrund av systemen och en bättre förståelse om förutsättningarna för varje system. Efter litteraturstudien kunde sedan ett typhus och beräkningsunderlag för jämförelsestudien tas fram.

Who runs the development? A comparative study of the construction of residential buildings in Nacka and Södertälje.The aim of this study is to identify actors involved in the initiation and implementation of residential house construction in two Swedish municipalities. This means who is taking initiative for new residential buildings, who affects the planning process, who finances these new buildings and who builds them. By exploring empiric material from the municipalities of Nacka and Södertälje, the above questions will be answered and by referring to pluralism, growth machine theory and regime theory a link to general theories of political science is made. The results found show that the analysed municipalities have quite different possibilities for acting and that these backgrounds are also important for which actors will take initiative for new residential buildings and which actors will be allowed to state their opinion during the planning process.

The review of Integrated green spaces in urban areas ? A case study of inner Brisbane highlight the significance of addressing characteristics, qualities and landscape values in our outdoor environment. The importance of green spaces to the wellbeing of people in the city and the ecological, social and cultural values they carry are widely recognised in the field of urban and regional planning. At the same time population growth, climate change and urban development put planners and scientists in a challenging position where new solutions must be put on the agenda in order to accomplish sustainability. Open space strategies, collaboration between stakeholders, public participation, learn from earlier failings and a ?value-led? approach facilitate the managing of open space. Brisbane is located in the fastest growing metropolitan region in Australia. The city´s open space landscapes offer cultural, geographical, recreational, social and scenic amenity assets, which make a major contribution to the regions identity they a wide world known for.

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.

The aim of this thesis is to examine the archivist's professional role in public authorities and discuss if, and in what way, the profession is effected by the new swedish process oriented archival description system. The study focuses on swedish authorities and does not make any international comparisons with other institutions. Neither does it investigate archivists workingin the private sector, but centers on public institutions.The survey is performed in five swedish public authorities, using interviews and observations. Grounded theory is used as a method initially in the purpose of keeping an open mark towards the object of study. The initial results led on to questions about how well the archivists perceived that communication within the authorities served, and how this in turn prepossessed their work situation and the professional roles in which they found themselves.

Throughout many years there have been discussions within the European Union (EU) regarding harmonization and improvement of accounting rules for companies with listed shares or other securities. The ambition exists to adopt, the within the union applied accounting standards, to those applied globally. These discussions lead the year 2002 to adoption by the council and parliament of international accounting standards (IFRS). The ordinance meant that all listed European companies have to adopt international accounting standards, accepted for application within the EU, for their consolidated accounts.During July 2003 the Swedish Government Official Reports issued a report (SOU 2003:71) stating, among other things, the differences and oppositions of implementing IFRS on a corporate level in Sweden, since corporate disclosure is regulated in Swedish law by Bokföringslagen (BFL) and Årsredovisningslagen (ÅRL). One of the main obstacles for the full implementation of IFRS is that a company?s annual report underlies the governmental taxation and an implementation of IFRS would affect this balance.

This study has a qualitative approach and deals with difficult issues that arise in connection to male violence against women in close relations. The purpose of this study is to bring clarity to why women stay in violent relationships. I have been studying two leading theories, one called the Normalization Process of Violence represented by Eva Lundgren (sociology and theology). The other leading theory is the Neutralization of Violence represented by Margareta Hydén (fil dr and leg psycho therapeut).I have also studied the fight between these two theories for the leading position in the research on male violence against women. Eva Lundgren presents her theory through a structural perspective.

Turkey?s nearly fifty-year-old aspiration for admittance to the European Union took a crucial step forward with the signing of the Ankara agreement in 1996. The aim of this thesis is to examine the trade effects that evolve from the creation of a customs union. Our objective is to study how Turkey?s trade patterns adapted to the liberalized trade by examining the effects on resource allocation, specialization and welfare.

Syftet med studien var att undersöka hur Parken Zoo använde sig av Facebook för att kommunicera med sina intressenter under en kris som drabbade organisationen hösten 2012. Med hjälp av en kvalitativ textanalys studerade vi de Facebookinlägg som Parken Zoo hade publicerat under krisen. Därefter genomförde vi en kvalitativ intervju med marknadschefen på Parken Zoo, som var ansvarig för kommunikationen på Facebook under krisen.Med hjälp av ett analysverktyg baserat på situational crisis communication theory och image restoration theory kunde vi avgöra vilka försvarsstrategier Parken Zoo hade använt i Facebookinläggen.Resultatet visade att Parken Zoo omedvetet hade använt många olika försvarsstrategier, men att tre tydliga budskap förmedlades i Facebookinläggen. Resultatet visade också att Parken Zoos syfte var att använda Facebook som ett dialogverktyg, men att de i själva verket använde Facebook för att sprida enkelriktad kommunikation.En slutsats vi kunde dra från studen var att det är viktigt för organisationer att vårda sina kundrelationer genom att bemöta intressenternas frågor och kommentarer på sin Facebooksida under en kris. En annan slutsats var att det är viktigt för organisationer att ha en god krisberedskap och att inkludera Facebook i den..
