The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

The main aim of my research essay is to examine two congregations, one in Sweden and one in Democratic Republic of Congo, how theology and the life in the church shape the cultural context. The analysis uses semi-structured interviews of two pastors responsible for organizing the Easter celebration in their churches. The interviews serve the purpose to reveal how they apply theology in their context, how they interpret the Easter celebration liturgically in relation to the early church and how they perceive the cultural development in the congregations Easter celebration 2010-11. To give complementary insights to the interviews I use computer-aided interviews with members of the congregations. The methodological approach is based on a study of contextual theological theories, Easter traditions in the early church, Easter theologies and then applying these theories in the interviews.

This paper examines and analyzes effects of the introduction of a new management control system tool within a Swedish public health organization, the Södra Älvsborg hospital, and its possible effect on organizational change. The new management control system tool, known as the SÄS-model, has been widely criticized for being too costly and with too small positive effects to be shown. Our approach has with that as a background been to examine whether the implementation of the SÄS-model and its balanced scorecard has been able to result in effects regarding organizational change. We have through a case study aimed to analyze how a management control system, much alike one that is typically used within foremost private organizations, can promote organizational change. Our results suggest that the implementation of the SÄS-model and the balanced scorecard has given the organization clearer visions and goals.

The work with this report has been focused on developing a methodology model for control at purchase. The methodology model covers parts classification, dispatching systems, batch shaping and more. The aim with the methodology model is that it will be used as an aid for a cost effective material planning to increase the value for customer.The work covers also a description of the present situation and the purchase process at Company X. Six parts have been applied, two from each class (A, B and C), in the methodology/model. The parts that have been applied are included in the flow between Company X and their supplier Company Y.Data have been collected trough literature studies, interviews and the company?s business system.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

ABSTRACT: Introduction: There are intentions from the Swedish government to provide guidelines and tools for a healthy social planning. The field is in a Swedish context relatively unstudied regarding psychosocial health and the neighbourhood. Aim: The study aimed to examine how social planning can affect the health of individuals. The focus areas were contextual and compositional factors related to individuals' psychosocial health and the contextual risk- and health factors that exist in the neighbourhood. Method: A literature-based study was conducted and 15 scholarly articles form the basis for analyse.

This report describes the construction and development of a control box, which is a tool for testing and verifying a certain model of Rapid?s built in staplers (model A6102). Basically the function of the control box is to interpret any errors that may occur in the stapler and to make it possible to test fire the stapler.The control box should be able to communicate with the stapler using a specialized communication protocol. The different data such as errors, firmware etc. from the stapler is presented in plain language on a display.

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..

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

The aim of this paper is to examine how confidence in co-operative behaviour of partner is reached in a relationship between an entrepreneur and a venture capitalist. A case study has been conducted on a Swedish football club that has involved venture capital in order to develop the organization. The paper presents a theoretical approach which draws on a control model of interorganizational relationships developed by Dekker (2004) and a model developed by Shepherd & Zacharakis (2001) illustrating how control, trust and confidence is reached in a venture capitalist-entrepreneur relationship. The relationship between the football club and the venture capitalist can simultaneously be seen as an interorganizational relationship and a relationship between an entrepreneur and a venture capitalist. Because of the complexity of the relationship, different control problems prevail.

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.
