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 investigation is to show how politicians state primary goals and how they break them down into secondary objectives within the sector of Child-and education area. This is supposed to create a general image on how the targeting process is handled within the public activity. Finally, this will lead us to what is necessary for the targeting process to work successfully within the public activity.  We have implemented a qualitative study within the two chosen municipalities. This case study is based on personal interviews that are conducted through semi structured questions.

Abstract This thesis is based on a case study of the drawn out legal process on the question of establish a limestone quarry in Bunge Ducker in north Gotland (Sweden). The current fields are located next to areas that are protected by virtue of being EU-certified Natura 2000-areas. Despite this, the Swedish governments and courts have not agreed in witch national interest that should be prevail when decisions are made on this issue. This phenomenon are reflected in the judicial process and different court have evaluate information differently in the case. A change among governmental actors where priority is given to the importance of national interest have occur in the later part in the process.

Participation, public art and participatory public art as phenomenons and subjects have been studied and discussed. With interviews and observations as a base, we have studied projects and discussed participation, effect and quality in relation to these. Furthermore we have looked at how the participatory art processes work in Sweden and England. This essay seeks to discuss the process of participatory public art and to emphasize the elements contributing to the quality of this process. It is up to us as planners to recognize the possibilities for a qualitative place. To mediate between different interests, for example between politicians and stakeholders, between economics and quality, between the place and its users, between individuals and the community, and in our case between artists, users and the municipality. Public art has gone from being about the product, an art piece, to becoming more of a process, from non interactive to interactive. Participation ranges from receiving information to play an active part in the process. Four cases have been studied, taken both from Sweden and England, showing the diversity of processes connected to Participatory Public Art. From interviews conducted in Sweden and England information and thoughts have been received and they show a higher degree of use of participatory public art in England, and also a higher consciousness.

The purpose of this bachelor?s thesis is to examine video games, gamers and gaming from an information science perspective. The purpose of the study is partly to study video games as a type of information system and partly to study gamers information use, information seeking and also the experience of gaming. A selection of five games have been analysed using a topology for video game analysis created by Espen Aarseth. A quantitative investigation has also been made, in the form of a web survey distributed through four Swedish online forums, the result of which was analysed using Carol Collier Kuhlthaus model of the information seeking process.

Around year 2004, a new service was introduced on the Swedish housing market with the purpose of increasing the sell price, namely homestaging. Homestaging means that a home gets in order before a open house, for example by removing personal affections or the leasing of new furniture. The phenomenon originates from the United States, where it has existed for several decades.Most components, but not all, that is included in the homestaging concept is tax-deductible and this has lead to several questions around the law and foremost within tax law. To elucidate this complexity of problems around the right to deduction for homestaging, the Swedish tax agency, Skatteverket, has formulated a letter stating the authority?s attitude towards the phenomenon.

This master thesis was carried out at ELFA, one of the largest catalogue distributors of electronics in northern Europe. ELFA offers a wide selection of products such as measuring instruments, fuses and screwdrivers. The master thesis handles the possibilities of an increase in the internal flow of products. The background to this problem is ELFA?s acquisition of two new companies, which brought the product range in the warehouse from 55 000 to 80 000 products.

Today it becomes more and more important to work with continuous improvements to stay ahead of the competitors. Pfizer in Strängsäs started working with continuous improvements in 2010. By the end of 2012, the company?s goal is to reach 24 improvements per employee at the factory.Their project has two main purposes; to examine the need and possibilities for visualization regarding continuous improvements at the production department and to develop a concept for visualisation of the entire factory?s continuous improvements.To attain the information required to examine the needs at the production department, interviews with relevant employees at the department were conducted. Using interviews as a benchmarking instrument was also helpful in getting different points of views.

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

The current debate regarding organizational strategies for sustainabledevelopment is influenced by the theory of global governance. Decentralizedstructures of the global society are taken to use in the realization of a sustainabledevelopment. New roles of transnational networks and partnerships raisesquestions of the ability of global governance to co-ordinate and implement longtermsolutions without assistance from centralized and hierarchic structures basedon government. The aim for this thesis is to illustrate the current conditions forwell-functioning networks of sustainable development and examine therelationship between global governance and government. Issues of participation,decision making and compliance are examined by a case study of the Marrakechprocess, a global process to support the implementation of sustainableconsumption and production.

The purpose of this thesis was to study how an internationalization process to China may appear for a small Swedish enterprise and to identify important factors that may be essential for the process. The focus extends from the point where the enterprise makes its first connection with China up to the point where they are well established. Their business is up and running and they have begun production. To gain a deeper understanding of the subject a gathering of existing theory and research articles was conducted. The gathering of theory yielded knowledge of different approaches and methods that can be used to implement internationalization and provided a greater understanding of cultural and regional differences in China compared to Sweden.

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.
