The aim of this thesis is to improve the control of urea injection at the combined power and heating plant Framtidens Gärstad (FTG). Tekniska Verken i Linköping AB is the owner of the plant.The FTG plant consists of a boiler where garbage combustion is done. From the combustion nitrogen oxides are emitted. These nitrogen oxides are hazardous to the environment. To reduce the nitrogen oxides, injection of urea into the boiler is used.

The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

This essay aims to examine managers experiences of control at the workplace within the property sector, and how these experiences differ between female and male managers. This study is a qualitative single case study that intends to offer a deeper understanding of a unique case and uses an abductive method approach. The essay is based on two main theories, Foucault?s (2003) theory of control and the gender system of Hirdman (1988, 2001) and is supplemented by previous studies of the modern workplace. The study is based on eighteen semi-structured interviews that aims to capture the participants personal experiences regarding control at the modern workplace, and the norms, surveillance, hierarchies, and self-discipline that make up this control.

Vobbla Racing is a racing team who has an online sales department that is in need of an upgrade to be more efficient and easier to use. Before this study their present homepage was anything but structured. The products were sorted in an illogical order which made it difficult for the customer to find a wanted product. The customer had to summarize the products, transport sums and other costs. The order had to be e-mailed or phoned in to Vobbla Racing Produkter.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

AbstractTitle:The Impact of Management Control Systems on the Purchaser Function - A study of Scania and Sandvik Authors: Mohammad Reza Akhbari and Johanna Sullivan Svensson Published: 2011 Keywords: Management control, purchasing function, impact, control, control instruments, Key Performance Indicators, measurement, communication and organizational structure. Background and problem formulation: In order for a company?s business idea or vision to be fulfilled, the management of a company needs assistance from various means to intentionally affect the operation in the desired direction. Management control concerns activities of both financial and non-financial character in order to implement the strategy of a company and to reach profitability. Since the purchaser function is responsible of spending 50 percent of a company?s total revenue, the function has an optimal starting point to be a key actor in the shaping and execution of a company?s strategic plan.

Södra Interiör har en anläggning i Kallinge där man tillverkar golv och paneler av furu. I takt med att produktionen har ökat har även lagernivåerna ökat vilket har ökat risken för att fel råvara används till fel produkt. Syftet med examensarbetet är att ta fram ett arbetssätt som minskar risken för att fel råvara används.Studien visar att något måste göras för att säkerställa att rätt råvara används till rätt produkt. Lagernivån och informationskvaliteten är andra problem som identifierats. Nyckelbegreppen för att lösa problemen är ordning och reda, information, framförhållning och utrymme.

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..

The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.

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 Regional Forestry Board in Värmland- Örebro needs increased knowledge on silviculture in broad- leaved forests. This thesis is an inventory of naturally regenerated broad leaved forests, and the results from the inventory have been compared with The Regional Forestry Board?s demands on regeneration results. The result of this inventory was that the regenerated sites were suitable for broad leaved trees, but only half the number of the stands fulfilled the demands of regeneration results of The Regional Forestry Board, mainly because of gaps in the stands. The gaps in the stands were mainly caused by lack of soil preparation and seed trees..
