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.

Title: Communicate ? to provide an opportunity Authors: Ida Eriksson & Petra LindbergTutor: Johan Grinbergs, Mälardalen UniversityExaminer: Cecilia LindhSubject: Bachelor's essay, Business AdministrationKeywords: communication, internal communication, channels, communication models, communication theory, information, organizationPurposeThe idea of this study was to describe how ABB Sweden?s internal communication and information appeared in Västerås. The aim is also to see what tools and channels they use to communicate information internally and see how employees perceive them in Västerås.MethodWe have read literature in form of books and articles that discuss theories on the subject communication including internal communication, channels and tools. Interviews were conducted with employees of ABB and were to serve as the basis for our empirical work. A survey by the Communication Center was made in the spring 2010 and was also the basis for our empirical work.ConclusionsThe communication has been increasingly from one-to two-way communication. To get a functioning organization, it is required that the internal communication in the first place will work.

Syftet var att undersöka om personers Locus of Control påverkar deras konflikthanteringsstrategier i kärleksrelationer. Hypoteserna var: H1: Det finns skillnader mellan personer med extern och intern Locus of Control när det gäller vilka typer av strategier de använder för att hantera kärleksrelationsproblem. 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..

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.

This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

By identifying effects that a buyout-firm has on management control systems in its portfolio companies, the aim of this thesis is to explain how such effects differs between the companies and finally to explain why the effects differs even though the companies are owned by the same buyout-firm. The study is conducted as a qualitative case study based on interviews with representatives from the studied buyout-firm and three of its portfolio companies.By analyzing the empirical findings with frameworks and theories within management control systems and value creation, we cannot only identify effects that are common for all portfolio companies but we can also observe differences between the portfolio companies.The identified effects that are common for all portfolio companies are: increased internal reporting burden, increased perceived risk of getting laid off among managers and co-workers and replacement of the board immediately after acquisition.The effects that are observed only for two portfolio companies are: increased focus on short-term planning, higher financial targets, replacement of company management upon acquisition and moving of decision authorities to higher organizational levels. Differences are observed although the portfolio companies are owned by the same buyout-firm due to: differences in management and co-workers equity stake in the portfolio companies, differences in business complexity and differences in planned exit-horizon..

Motivation är en viktig drivkraft för individers beteende. Den har betydelse för att handlingen såväl påbörjas som uppehålls. Forskning inom området har konstaterat att motivation uppkommer av både inre och yttre faktorer samt att en del handlingar är relativt omotiverade. Den hierarkiska modellen för inre och yttre motivation anger även att motivation förekommer på flera nivåer inom individen. Studien undersökte relationen mellan högskolestudenters kontextbundna motivation, globala självkänsla och generaliserade locus of control.

Internal communication is an important factor in organisations today. For many system development teams it?s critical that the communication works well. Without communication, success would be impossible. This study aims to highlight the effect communication has on the members of agile project teams.

The purpose of this thesis was to study managers in the tourism market who works with internal marketing towards their personnel. A case study with two tourism providers, Hotel La-ponia and Mix Ranch, was performed. The cases were based on personal interviews with the hotel manager at Hotel Laponia and with the owner of Mix Ranch. The research questions were based on why tourist providers use internal marketing and how tourist providers use internal marketing. The findings were that it was regarded as very important to have moti-vated, satisfied, and properly trained personnel in this business because they are the ones who have direct communication with the clients and they are an important issue to help the com-pany to success.

En majoritet bland ledare i olika organisationer har en bakgrund som storasyskon eller ensambarn (Hudson, 1990). Denna studie genomfördes för att få svar på om personer med ledaransvar skiljer sig åt gällande syskonplats och locus of control jämfört med de personer som inte har ledaransvar. Ledare och medarbetare på en statlig myndighet svarade på en enkät gällande plats i syskonskara, erfarenhet av ledarskap och locus of control. Resultatet visade att sistfödda i detta urval hade en högre grad av intern locus of control än förstfödda vilket kan tyda på en annan typ av sistfödd på denna myndighet. Urvalet var dock bristfälligt (N = 48) och slutsats kunde inte dras utan att riskera ett felaktigt resultat..
