This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

The aim of this thesis is to analyze and explain the similarities and differences in management control between a private and a public primary care company. A comparative case study was developed based on one public and one private primary care company in Stockholm County Council. The framework of Otley (1999) was used to define and limit the area of management control systems, according to his five factors. For the analysis of the empirical results Hood's (1995) seven doctrines of New Public Management was applied, and customized to fit the purpose of the study. The results indicate that the differences between the two organizations are very limited.

Traditional financial management has lately been criticized, since it gives inadequate and unilateral information for decisions and strategy of the operation. The purpose of this essay is to investigate if a balanced scorecard is able to work together with a budget and become a stronger control system for the management. Essential theory underlies the gathering of data as well as the analysis, and the empirical investigation is based on personal interviews. The conclusions drawn from my analysis are that two parallel control systems could complement each other?s weaknesses.

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.

Titel: Innovate or Stagnate! ? Open innovation in manufacturing small and medium-sized businesses in Småland.The purpose of the study is that, from a leadership perspective (innovationmanagement), create a better understanding of open innovation in manufacturing small and medium-sized enterprises. The study therefore intends to contribute to the understanding of how open innovation processes leads to greater innovation in manufacturing small and medium sized businesses.We have used a qualitative research method and adopted an abductiveapproach. We made interpretations and created meaning based on our research results.Our theoretical framework is based primarily on Chesbroughs (2003) research on open innovation. Based on this model, we have selected a number of other theories, which we perceived as prerequisites for small andmedium sized companies in open innovation processes.

The aim of this Master?s thesis is to examine the function of the budget as a means of control within an organisation in the public sector. To accomplish this, a case study has been conducted on a certain business unit within Luftfartsverket responsible for providing Air Traffic Control services. The thesis is built on a framework of contemporary theories of budgeting and includes a brief discussion of the weaknesses usually associated with the traditional budget. The conclusion of the study is that the use of budget as a means of financial control within Luftfartsverket is not efficient enough at the moment.

Social control in different forms has existed in all known societies. This control has taken different shapes and expressions. In older smaller communities there was a collective control among the citizens. In modern societies the state is trying to control the lives of the citizens. These control mechanisms can be seen as both freedom-reducing and freedom inducing depending on which concept of freedom one upholds.

This study focuses on the politics around ecological sustainable development in Sweden today, with emphasis on urban development, building and living. The starting-point for this study is the environmental adapted city district of Stockholm, Hammarby Sjöstad. The primary focus of the study is to investigate what means of control the environmental investment in Hammarby Sjöstad is expressing, and to elucidate their ideological, political and social implications. The empirical material is primarily based up on the local Hammarby Sjöstad environmental program along with qualitative in-depth interviews with citizens of this district. The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.

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 purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

Background: Inter-organisational ways of working have become more and more common during the last decades. In order to attain efficiency and productivity, such inter-organisational relationships need to be governed and controlled. However, studies have shown that inadequate control is one of the main reasons for why inter-organisational relationships fail. One of the means that can be used for governing and controlling a business is management control. The use of management control in inter-organisational contexts is a quite unexplored area of research at the present time, which might seem somewhat surprising considering the fact that inadequate control is a common explanation for why inter-organisational relationships fail.

The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.

AbstractThis study focuses on three generations of Kurdish women's view on honor. The study is a qualitative research based on three individual interviews. The aim of this study is to examine how three generations of immigrant women from a culture of honor is influenced over time by the majority culture and its values together with how these women affect each other mutually both consciously and unconsciously within the family. The study is based on two questions: What does"honor" mean to the three generations of women who are Muslim and Kurdish? Did these three generations of women?s idea of honor change over time as they have lived in Sweden? Results of this study have shown that the concept of honor has its focus on the woman's body, sexuality and chastity.
