Riskkapitalbolags påverkan på styrning i sina portföljbolag: En studie om utveckling av styrsystem i svenska Venture Capital finansierade företag.
The aim of this study is to investigate which management control mechanisms evolve in companies that receive funding from Venture Capital companies and why the management control systems evolve in the way that they do. A case study was performed on three Swedish high technology companies, that all received funding from Venture Capital companies for the first time in 2006. Merchant?s framework, defining all management control mechanisms as either, results control, action control or personnel control, was used to structure the study. Results show that the companies that received Venture Capital all increased the use of management control mechanisms within results control, action control and personnel control.
Traditionell ekonomistyrning vs modern verksamhetsstyrning : en fallstudie av ett växande företagsstyrfilosofi

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..
Health Locus of Control och impulsivitet i relation till träning : en studie om universitetsstudenters träningsbeteende
There are many aspects which must be taken into consideration when studying individuals? need of exercise. The study investigates if impulsivity and Health Locus of Control affect the continuity of physical practise. The main presumption was that individuals with high impulsivity, high Powerful Others and high Chance Health Locus of Control, would have a significantly harder time to maintain a continuous physical activity. The survey used two standardized tests to measure impulsivity and Health Locus of Control and in order to be able to measure the insensitivity and the periodicity of physical exercise, a test was developed by the authors.
Energieffektivisering av luftningssteget på Käppalaverket, Lidingö
This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.
Utvärdering av reglerstrategier i luftningssteget på Himmerfjärdsverket
På Himmerfjärdsverket söder om Stockholm finns åtta luftade bassänger för biologisk rening av avloppsvatten. Genom att syresätta vattnet skapas en miljö där mikroorganismer kan arbeta och omvandla organiskt material och ammonium till koldioxid, vatten och nitrat.Bara luftningen av dessa aktivslambassänger på Himmerfjärdsverket står för nästan en femtedel av verkets totala energiförbrukning och är därför en viktig process att optimera. Under hösten 2011 har några olika reglerstrategier utvärderats genom fullskaleförsök på verket. Denna rapport handlar om dessa försök. Arbetet bygger på ett tidigare utfört examensarbete vid Himmerfjärdsverket och ingår i en större forskningsstudie som leds av IVL Svenska Miljöinstitutet i samarbete med Uppsala Universitet.
Interorganisatorisk styrning av leverantörsrelationer inom lågprismodebranschen: -En fallstudie av lågprismodeföretaget BikBok
This thesis concerns the control of outsourced interorganizational buyer-supplier relationships in the low-price fashion industry. A qualitative case study has been performed on two supplier relationships of a low-price fashion company. By identifying specificities of the industry and relating them to control problems and their implications on control solutions, the thesis has established a relation between industry specific characteristics and the way companies in the industry control their supplier relationships. The analysis is based on a theoretical framework created by Dekker (2004). Amongst other factors, the difficulty to define, quantify and measure the design variables of a fashion good, the high heterogeneity between individual products and the difficulty to predict the trend based demand, create high coordination requirements as well as appropriation concerns solved through extensive formal control.
Vad gör en livsmedelsinspektör egentligen? : en studie om livsmedelsinspektörens yrkesroll sedd ur olika perspektiv
Aims The aim of this study was to investigate how personnel within food control are regarded from different perspectives and to find the answers to the sub questions:- what is included in the profession of food control?- what are the requirements for personnel within the profession of food control?- how is the profession perceived from different perspectives?- how do personnel within the profession of food control estimate their psycho social working conditions?Method The study included 68 individuals (34 female and 34 male) and was conducted via observations, web-based surveys and survey-based interviews. Conclusion - The study was feasible.- The overall goal of the study as well as the research questions were answered to and contributed to clarify what is included in the profession of food control. - Quality measures should be implemented to greater extent within the development of the national food control system..
Modellbaserad prediktiv reglering av en dieselmotor med variabel geometriturbin och återcirkulering av avgaser
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.
Budget som styrmedel ? ett effektivt verktyg eller ett onödigt ont?: En fallstudie av den ekonomiska styrningen inom Luftfartsverket
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.
Effekter av Zeoliter i Biogasproduktion
Biogas är benämningen för metangas (CH4) som är producerad via anaerob (syrefri) rötning av biologiskt material. I Linköping finns en av Sveriges största biogasanläggningar. Anläggningen drivs av Svensk Biogas AB som ägs av Tekniska Verken i Linköping AB (publ.). I anläggningen rötas stora mängder proteinrikt substrat vilket leder till höga halter av ammoniak (NH3) och ammonium (NH4+) i rötkammaren. Ammoniak (NH3) är toxiskt för de metanbildare som i en välmående process står för den största delen av metangasproduktionen.
Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt
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..
Ekonomistyrning i interorganisatoriska relationer
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.

Intern kontroll : Inom mindre grossistföretag
Accounting is a well discussed topic, and an important tool that allows stakeholders and others to interact with the companies. To gain credible reports, the companies require maintenance, activities and monitoring. Wholesalers account for approximately 20% of Sweden's net and is increasing at a steady pace. Few studies on wholesalers are acquired and the internal control has shown to be important for the preparation of the financial statements.Therefore the study will be focusing on the smaller wholesaler?s internal control, all the way to the financial statements.
