The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

The purpose of this study is to investigate how power is distributed in the mathematics classroom and how students achieve agency when ICT (Information and communication technology) is used as a teaching tool. Three learning situations, structured by mathematics, are analysed: in the first situation mathematics is taught in a traditional way, in the second mathematics is taught in interdisciplinary projects, and in the third mathematics is taught using ICT as a pedagogical tool. The theoretical concepts of power and agency are used as analytical tools within a socio-political framework. The concept of power is used to assess the students? ability to influence their learning and degree of inclusion in the three learning situations.

This thesis paper is based on Ian Manners Normative Power Europe-theory with a focus on EU?s military operation in Somalia. By examining documents from EU institutions in the form of reports concerning EU NAVFOR ? Operation ATALANTA ? EUTM Somalia ? EUCAP NESTOR. This study shows that the Normative Power Europe-theory can get expressed and that the EU continues its normative statements in Somalia. This result is an interesting contribution to the theory of Normative Power Europe witch have gotten a lot of critic about how a military operation should effect and diminish the theory..

Hofstede constructed a culture dimension called Power Distance, measuring the inequality of Power. Germany and Sweden have relatively similar values according to his world-renowned research. But a series of interviews of Swedish entrepreneurs in Germany shows that these perceive a large difference in inequality of power in the two countries. This essay seeks to explain the difference between these subjective-qualitative experiences and the objective-quantitative data of Hofstedes Power Distance Index. We propose that a combination of differences in communication, exercise and visibility of power and formality influence the way Power Distance is perceived.

This thesis is a feasibility study for a future product development project. The purpose ofthis project is to evaluate the possibilities and difficulties associated with the design of anelectric power assist servo for all terrain vehicles (ATVs). The project has been carriedout in collaboration with Nira Control AB. Nira designs and manufactures electric andelectro mechanic products mainly for the motor sport market segment.Nira Control AB is developing a fuel injection system for a new line of large ATVs oncommission. To be able to compete with manufacturers like Yamaha and Honda thecommissioner should be able to offer optional power assist steering.

The purpose with this paper is that trough a description of the management control at Jitech AB find out if traditional management control have been abandoned for benefit for modern management control and in which extent the transition have happened. Further is the second purpose with this paper to find out which decisions that lies behind the design of the management control and how these are in opposition to with the theory..

This thesis treats the normative power of the European Union and its affect on Macedonia. The main purpose has been to look closer with the use of the application of Ian Manners theory of normative power on the Macedonian case. The focus will be to answer the following questions: Does the European Union act as a normative power in relation to Macedonia, if so, how are these values diffused? Has there been any effect of the spreading of these values? Based on six interviews and the available material of European Union strategies for the Macedonian membership I have attempted to understand to what extent the European Union?s normative power has had an influence in Macedonia. The result of my analysis is confirmation of the European Union as a normative power in Macedonia and the understanding of the methods of application..

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

The aim of this thesis is to examine how salesperson control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the control system. The main finding is that the company?s management control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..

Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

Problem: What are the characteristics of Polykemi?s management control system and how is it affected by growth? Purpose: To describe and analyse the management control system of a medium-sized family-owned company from the perspective of Simons? Levers of control. Research design: An abductive, interview-based case study of Polykemi AB. Conclusion: Polykemi?s management control system is primarily a traditional one which is rather strong in terms of Levers of control.

Bakgrund: Under senare år har många företag valt mer processorienterad inriktning påverksamheten, framförallt i syfte för att förbättra kundvärdet. Många företag har enmer hierarkisk struktur i utgångsläget, vilket innebär att vertikal och horisontellstruktur kombineras. Ett vanligt misstag är då att nya processorienterade styrmedelinförs, utan att existerande vertikalt orienterade styrmedel tas bort. Detta leder tillatt företagets styrmedel sänder ut motstridiga styrsignaler. För att öka företagetsmöjlighet att uppnå uppsatta mål, så krävs det att dess styrmedel är kompatibla.I sämre tider är det vanligt att företag formulerar mål med Net Working Capital somgrund.

This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.

Abstract:The purpose of this study is to examine what actually makes Russia an incomplete democracy, despite of all the formal democratic institutions and legal democratic rights.The research method used for this essay has been qualitative case study, which strives to answer two research questions: Which democratic principles are not respected in Russia? How does the executive power control the political arena? The theoretical framework used for this study consists of a model based on Dahls Polyarchy theory and the Rule of Law concept. The conclusions points out that very little have formally changed in Russia regarding democratic rights and the constitution. The democratic decline is due to political manoeuvres and undue political influence. There is no proper division of power and the executive powers are not controlled by a system of checks and balances.
