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.

Aim: To investigate if physical exercise in combination with coaching will reduce pain and improve knee function in patients with mild to moderate osteoarthritis in the knee compared to physical exercise alone.Method: The study consisted of 42 patients who were randomized to either an intervention group or a control group. Both groups followed a standardized training program at home, but the intervention group received additional support with regard to the aim of their training, as well as extra coaching during the training period of ten weeks. A Visual Analog Scale (VAS) was used to evaluate the patients? pain. A 10 metre walking test, the Index of Muscle Function (IMF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) were also used to evaluate knee function.

The aim with this project was to describe how nursing staff working in the home care environment perceive their level of knowledge regarding mental ill health and if this level of knowledge is sufficient / insufficient in their dealings with mentally ill patients. The study is empirical and a qualitative method has been used. Questionaires have been used and interviews have been carried out with nurses working in the home care system and data has also been collected from previous research in this area. Result The result show that home care nurses consider that they have inadequate knowledge of treating patients with mental ill health and they seek more training, guidance and collaboration with psychiatric nurses. Conclusion Increased knowledge of mental health care and continuous guidance would make home care nurses more confident in their dealings with patients suffering from mental ill health.

H2: Personer med intern Locus of Control har större benägenhet att använda sig av relationskonflikthanteringsstrategin Kompromiss i sina kärleksrelationer. H3: Kvinnor påverkas mer än män av Locus of Control när det gäller vilka typer av strategier de använder för att hantera kärleksrelationsproblem. Deltagarna var 172 studenter.

The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

The purpose of this study is to highlight the second home sector in Sweden and Denmark, in a comparative study of regulations for the second home market, and residence requirement. Two attractive second home island destinations is being compared in Ven, Landskrona and Gudhjem, Bornholm. The study addresses issues such as the local effects of a regulation of the second home market get at a local level, and the effects generated by deregulation, as well as local people's opinions about second home regulation in a popular second home area in southern Sweden. This has been examined using a mix between qualitative method and quantitative methods, and the study is based on six semi-structured interviews from informants from Ven, Bornholm, and Gudhjem which has been analyzed throughout a thematic analysis. In addition to the interviews, diagrams from the Central Bureau of Statistics of Sweden and Statistics Denmark, and various real estate websites, and a field observation from Ven and Gudhjem will be presented.The result shows that show that the discussion on residence requirement has been going on for a long time in Sweden and Ven, but the local organizations found more disadvantages than advantages and are now looking in to other solutions, while other locals believes that there are more advantages with a residence requirement. In Denmark it?s revealed that there is recently started discussion between municipal decision-makers and local organizations about the regulations, and if it should be abolished or not.

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..

Föreliggande studies syfte var att undersöka validitet och intern konsistens för den svenska översättningen av Impaired control scale (ICS), en självskattningsskala som mäter grad av kontroll av alkoholkonsumtion. ICS består av subskalorna; Attempt control (AC), Failed control (FC) samt Predicted control (PC). Svar på ICS sammanställdes från respondenter (n = 203) som behandlats för alkoholproblem vid mottagningar i Västra Götaland. Faktoranalysen visade en bakomliggande faktor för AC, och två faktorer för FC respektive PC. Den interna konsistensen var god.

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.

The purpose of this study is to investigate the unaccompanied children's experiences of the support offered at group homes intended for this group.

The survey aims to investigate and analyze how the image of Sweden and "Swedish character? is produced in the correspondence between Swedish immigrants and family at home, compared to how the image of America and the U.S. is produced. The starting point is the concept of identity, which is shaped by the social group a person belongs, which can lead to stereotypes are formed. How does the Emigrant describe his new life in letters home to Sweden? What comparisons are made? What memories are passed from the time at home? How does the picture changes over time? How does the stereotypes change over time? The material used are remnants and secondary sources in the form of correspondence between emigrants and their relatives back home.

The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.
