This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.

The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.

The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production.The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with thenmeasured time of usage.

The aim of this study is to illuminate and discuss a case of political steering, specifically Managment-By-Objectives (MBO) in Swedish municipalities, from a democratic perspective. The essay examines a discrepancy between MBO in the Swedish municipalities and democratic theory.To fulfil the aim of the study one leading politician and one leading civil servant from five municipalities have been interviewed on this matter. This material is discussed in the light of a democratic theory constructed specifically for this essay. The democratic theory consists of three main democratic values in the democratic process: debate, transparence and the ability to demand political accountability.The main conclusion is that there is a contradiction in the use of MBO and the democratic values of debate, transparence and the ability to demand political accountability. MBO has resulted in a lack of debate and transparency and furthermore, it has made it increasingly more difficult to demand political accountability..

This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.

Studiens syfte var att undersöka om det fanns skillnader i personlighet och val av konfliktstil beroende av vilken placering respondenterna hade i syskonskaran samt om Locus of control skiljde sig mellan olika åldersgrupper. Samband mellan chefers konfliktstil och personlighet undersöktes också. De 103 respondenterna som var mellan 25-75 år, 63% män och 37% kvinnor, besvarade en enkät som bestod av demografiska frågoroch arbetsrelaterade frågor om chefskap. Tre test användes; ett personlighetstest, RottersLocus of Control och Thomas-Kihlman?s konfliktstiltest.

In this bachelor thesis, diagnostic methods for one of Siemens stem inlet control valves have been developed. The work has taken place during ten weeks at Siemens Industrial Turbomachinery AB in Finspång. The company produce steam- and gas turbines and also provides service and maintenance. The purpose with this project has been to develop diagnostic methods that oversee the health of the control valves. By using the developed methods you will know when it?s time for maintenance.

Background: Performance measurement as a management control tool has received considerable academic attention. As the number of inter-organisational relationships, such as customer-supplier relationships, increases, there is a new scope for performance measurement as a management control tool. In order for a company to assess the effectiveness of its supplier relationships it has to define, measure and evaluate variables that are critical for the success of the relationship. The role of management control, and thereby of performance measurement, has increasingly been discussed in theory. However, empirical research in this area is still somewhat limited.

In the recent years auditing scandals all around the world, deficient internal control has attracted a lot of attention. This has contributed to further requirements on insight and internal control. Those scandals have seriously damaged the auditor?s profession and contributed to a reduced trust among the public. Therefore an extensive work to recover and stringed the trust was started all around the world.

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

The aim of this Master?s thesis is to study the effects that geographical distance have on the control systems in a scattered organization and how this, ultimately, affects the employees in terms of loyalty and motivation. In order to do this, a case study has been conducted on a multinational travel group and its local branches in Thailand. The study is based on a selected number of theories focusing mainly on control systems in multinational contexts as well as on theories regarding communication and autonomy. The conclusion of the study is that geographical distance has led to a rather large autonomy for the local branches and that the headquarter to a large extent rely more on formal control.

A degree thesis about quality control and assurance in construction. Made in cooperation with Wästbygg. An analysis was made of the self-monitoring control that is conducted during the construction. The data was collected from interviews from personnel employed by Wäsbygg as either work-leader, project-manager or quality- and environmental-coordinator. During the study there was also a review of the literature in the subject.

Recent years have been very turbulent for most private equity firms. Especially the financial meltdown in global economy has affected the industry, but also the public pressure has made private equity houses change their control strategies towards more conventional methods used in public companies. This thesis aims to put light on the control methods used in listed private equity houses which use a buyout strategy. The paper describes how the control methods change over the different phases the asset experience and how different value generating strategies use altered control methods. Using Merchant's (2003) framework for management control systems and Berg and Gottschalg's (2004) research on value generating strategies in buyouts the thesis shows that action controls as designing instructions for the board and a business plan, together with goal alignment is the commonly used control strategy directly after the acquisition.

In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.
