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.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems.

Målet med uppsatsen är att åskådliggöra vilka fördelar, nackdelar och effekter användarbaserad systemutveckling har för den administrativa delen av en organisation. Intervjuer har gjorts med en chef och en controller på ett större svenskt företag samt med en expert inom området för användarbaserad systemutveckling. Undersökningen visar att fördelar som ges vid användande av användarbaserad systemutveckling är t.ex. att organisationen och individen blir mer produktiv, får en mer flexibel miljö att arbeta med och blir mindre beroende av konsulter. Nackdelar har visat sig vara att organisationen kan försätta sig i en situation där de blir beroende av den person som har utvecklat ett specifikt system och kvaliteten på underhåll kan även försämras när användarna utvecklar själva.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

Målet med denna studie är att framställa en modell för sannolikheten för skred i Cuenca del Arga i Navarra, Spanien, med hjälp av GIS och oskarp logik. Utifrån denna modell framställs en karta som visar områden där det finns sannolikhet för skred. Övergripande har metoden skett i fyra steg. Först har en skredindexkarta framställts, sedan har medlemsfunktioner skapats utifrån dessa med hjälp av skredriskparametrar. De ingående parametrarna har varit sluttningsvinkel, topografisk fuktighetsindex, avstånd till vattendrag, jordmån och markanvändning.

This thesis studies the negative impact that control signal saturation may have on a controlled system. Different methods that are used to compensate for this problem are also studied and evaluated. Both sensitivity to disturbances and the effect the method has on the systems'ability to follow a reference signal will be examined. Stability will be discussed, but no conclusions whether the systems are stabilized or not can be drawn. Control signal saturation will lead to a slower behavior in general.

Problem: Ekonomer i IT-projekt är ett väldigt outforskat område. Frågan är om ekonomens kompetens utnyttjas och dras nytta av i projekten. Vi vill se vad ekonomen kan ha för roll i IT-projekt och om de kan tillföra något för att förbättra projekten. Syfte: Syftet med uppsatsen är att föreslå roller och arbetsuppgifter som kan passa en ekonom i IT-projekt. Metod: För att kunna nå vårt syfte har vi använt oss av kvalitativ metod.

The role of the quality manager has evolved from being a quality controller to work with a more global business. Within many organizations in Sweden, however, the traditional role of the quality manager's remains and the tasks categorized as quality control still takes up most of the quality manager's time. The survey conducted as part of this master thesis shows that the quality manager in most businesses has multiple roles in addition to the role of quality manager, which can create a role conflict. One consequence of this is that each improvement is not given priority due to time constraints. Although the importance of a clear and committed leadership is the key for succeeding as the quality manager.

This qualitative study examines how emergency people are framed in Swedish evening-, and local newspapers during the forest fire in Va?stmanland, Sweden 2014. The study also includes if there is any difference between the framing due to the location of the newspaper. The study is based on qualitative text analysis. The theoretical basis is representation, framing theory, media image, media logic and a few conceptions from crisis communication theory.

The purpose of this essay is to investigate how the Swedish media framed the political party, the Swedish Democrats, two weeks prior to the election of parliament in 2014. This essay starts with the historical background of the political party, the Swedish Democrats, and continues with the theoretical framework for the essay. The theoretical framework consists of three theories: framing, media logic and media?s role in the democratic society. The essay?s main problem is presented as the question: What media image was there of the Swedish Democrats before the election of parliament in 2014? The main problem is answered by using a quantitative content analysis on the essay?s empirical material, 68 news articles from four Swedish daily newspapers.

The aim of this thesis is to investigate how municipalities handle planning of megaprojects. The term megaproject here refers to a large project in terms of time, space, investments, numbers of agents etc. With an increasing importance of the phenomena the need of discussing the role local politics could take in this process is important.How do municipalities handle the difficulties that come with megaprojects and what roles do they take in their work with megaprojects? These empirical questions are tested on a case where the municipality of Lund works with the megaproject European Spallation Source (ESS). A theoretical question discusses the megaproject in the light of governance and government, and structures the analysis around these two important terms.Different parts of the municipality handle there part of the planning from there own logic.

The Common Agricultural Policy has been a burning topic for debate for severaldecades. According to the CAP:s opponents it's effects include pollution, market distortionsand not least a huge expense for the European union.In this study we seek to explain why the CAP has remained almostunreformed since it's constitution in the 1950:s. The means by which we do so isa case study where we analyze the CAP by using three different theories; liberalinter-governmentalism, realistic trade theory and new institutionalism.In the final chapter we conclude that the theories complement each other. Newinstitutionalism explains the rigidity of the CAP. The liberal perspective explainsthe origin and the logic behind the policy whereas the realistic point of view putsthe policy in the light of an international economic theory and recognizes nationalpolicy makers roll in the inflexibility of the CAP..

The focus of this thesis is upon how conceptions of globalization is created by the labour-organizations Lands-organisationen (LO) and Svenskt Näringsliv. It is possible to discern two arguments for globalization in the texts, economy and democracy, and it is around these that the discourses of globalization are being constructed. Economy turns into a basic logic in the discourses of globalization. How to perceive the role of economy, as positive or negative, differs. Still, there is an agreement of the influence of economy.

Syftet med den här uppsatsen är att beskriva och analysera hur controllerfunktionen är fördelad inom en organisation, samt att diskutera orsakerna till detta.
