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 master?s thesis is to examine how pupils with Swedish as a second language and school librarians perceive the concept of pleasure of reading and the feeling of being a part of society. Our research is based on qualitative interviews with eight students in grades 6-9 and from two different schools. We have also interviewed two school librarians in these two libraries. As a method of analysis, we used phenomenography because it is the informants' perceptions of the phenomenon of pleasure of reading that we investigate.

This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.

The aim of my study is to critically analyse the discourse behind two different integration projects in Sweden, by using post colonial theory. My hypothesis is that many projects intended for increased integration includes a view of immigrants as the ?Others? which can be seen in how one talks about integration and culture in the discourse behind integration projects.The first of these two projects aims at increased diversity in the cultural sphere, organized on at state level. The purpose of the second project is to increase the communication and results for schools in areas with a high rate of immigrants in Malmö. In my study I make a discourse analysis of the discourse behind these two projects and study how they are motivated and how one conceptualise culture and integration in these documents.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Asperger´s syndrome is a state with certain difficulties in social relations, communication and perception. People with Asperger´s syndrome often have a special interest for a certain topic. The main purpose of this study was to describe how grown people with Asperger´s syndrome make sense of living with Asperger´s syndrome. The inquiry was based on semi-structured interviews with eight persons with Asperger´s syndrome. We reached those subjects trough interest organisations for people with Asperger´s syndrome.

The common asylum and migration policy of the European Union is a struggle between a strong belief in the protection of human rights and the need of strong and secured borders. This paper highlights the dilemma that occurs in the common asylum and migration policy of the European Union. What happens when the union have to choose between liberal standards with high priorities to human rights and a realistic focus on security? The aim is to study the asylum policy presented in the Stockholm Program, and thereafter evaluate what kind of character the union has itself. By an ideal type analysis of the Stockholm program from 2009, the common asylum policy is divided into either liberal or realistic ideas.

Nearly half of the worlds population is individuals under the age of eighteen. The UN Convention on the Rights of the Child state in its first article that a child is ?every human being below the age of 18 years?. Our aim and purpose with this essay is to problemize this broad definition. Our hypothesis is that the definition brought by the UN Convention on the Rights of the Child is too wide and therefore brings difficulties when children of different ages beneath eighteen should and shall be treated the same.

Rapporten är skriven på svenska. För att utveckla användarvänliga system finns ett flertal riktlinjer angående hur man ska designa systemet. Rapporten tar huvudsakligen upp de designprinciper som Professor Donald Norman utvecklade, och som behandlar varje område i ett informationssystem. Det finns även andra riktlinjer som beskriver användarprinciper och universal design, och som med fördel kan följas vid design av ett informationssystem. En grupp på North Carolina State University i USA är en av många som har utvecklat sju principer för att behandla användarvänlighet[1].

The main objective of this study has been to explore how art therapists experience the visual art´s that can be used in the promotion of health among people with depression - and anxiety disorders. The concept of SOC- sense of coherence has been a central term and a link between imaging and SOC were identified in the study. The underlying method in the study was a qualitative form, where semi-structured interviews were used. Through a strategic- sample five female art therapist were contacted, who all came to participate in the study. The study is essentially based on hermeneutical method and the analysis of interview material has been analyst by using thematic analysis.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

The aim of this thesis is to analyse the most common economic effects of countries pursuing trade facilitation. Trade flows are constrained by non-tariff barriers and through trade facilitation these barriers can be decreased. We will study the effects of trade facilitation from a theoretical perspective and evaluate a number of empirical studies. Several different trade barriers will be identified as well as those regions and countries that will gain the most from trade facilitation. We draw the conclusion thatlarge gains would prevail for all countries and that the consumers, businesses and the state all benefit from trade facilitation.

The European Union provide 27 % of total volume raw milk produced in the world. This number is steadily decreasing due to that the world milk production increase is more rapid than EU production growth. The growing middle-class change the demand for food, a higher standard of living increase the demand of milk products as well as other various animal products. Since 1984 the EU milk quota has limited the supply from EU, but the quota will expire April 1st 2015. The European Milk Board expect that the removal of quotas will make the farm gate price decline.

Access to correct and updated intelligence about our environment is in an increasingly degree considered important in the private as well as in the public sector. At Mälardalens University, competitive intelligence as an area of research is closely related to Information Design - a multidisciplinary consideration which goal is to improve the receiver´s understanding of intended messages. This study was conducted in order to find out how Information Design was representedin different kinds of literature regarding Competitive Intelligence. Also, it describes the main focus areas concerning Competitive Intelligence in the same literature. Through an explorative "pearl-growing" method combined with searches through referrals, 60 different sources provide a broad basis for analysis.
