For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

The purpose of this thesis is to shed light on the various factors that influence the balancebetween the working lives and family lives of social workers. The research questions posedwere: Do social workers consider there is a conflict between their working lives and familylives? Which factors make maintaining a balance between working life and family life moredifficult and which make it easier to do so? How do social workers describe equality betweenthe sexes in their own family? Regarding methodology, the selection method is strategic andcombines data sources with quantitative and qualitative methodologies. The material collectedand via online survey, targeted to 120 municipal employees social workers in a district councilin a big city, and through interviews with four social workers in a rural community. The studywas performed using gender theory and the demand-support-control model.

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 starting point for this thesis has been the great process of change that Swedish municipalities now arefacing due to the political directive of offering full-time employment to all part-time employees. The aimof the research is to create a decision support model for Swedish municipalities, which simultaneouslyintroduce the offer of full-time employment and an internal personnel pool. The factors that mayinfluence the personnel?s choice of employment level and the quality of the outcome, thus the financial result,are we also aiming at explaining. The empirical observations were found through secondary data as well asobservations from the municipality of Göteborgs Stad.

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.

We have chosen to write our essay in collaboration with Varbergs kommun, where our starting point is to improve energy efficiency by management control. Their occupation separates from a pure profit driven corporation and therefore the management controls have to be adapted accordingly.  The reason why we have chosen to write an essay about the management control opportunities to improve the energy efficiency depends on two different reasons. The first reason is that we find it very interesting, how with support from the management control it is possible to improve different parts of the operation. And the second reason is that Varbergs kommun expressed a wish that they wanted to improve their energy efficiency process.The purpose of the essay is to describe and analyze the opportunities with support from the management control to help improving the process of energy efficiency in a municipal operation.

This paper aim to present a model for evaluating what we choose to call HTML-frameworks, a framework that contains a set of CSS layouts and occasionally JavaScript support, based on the characteristics of the software quality standard ISO/IEC 9126-1. The methods used to produce this model is based on a field study that involved making a web portal with the help of a HTML-framework, some relevant literature and an analysis of the framework based on the characteristics of the ISO/IEC 9126-1 standard. The result was a model based on twelve different characteristics; functionality, web browser compatibility, collaborative skills, user-friendliness, documentation, visuals, graphic layout, performance, activity, professional support, replaceability and license. This model should be viewed upon as a suggestion to what a model for choosing HTML-framework could look like, because we haven?t had the time to test it in a real situation, so further studies are needed, and we believe there could be improvements made in the objectivity of the assessments of the characteristics..

AbstractThe purpose of this thesis is to highlight the organization's importance to teachers' working environment. Through a survey conducted at a primary school in New Zealand and at a primary school in Sweden, teacher perceptions of their psychosocial work environment were compared. This study has answered the questions: ?How does a teacher at a school in New Zealand and at a school in Sweden view their psychosocial work environment from an organizational perspective?? and ?What are the similarities and differences in psychosocial working environment between a school in New Zealand and a school in Sweden?? The results were analyzed based on Karasek and Theorells demands-control-social support model. The study shows that teachers at both schools are experiencing high demands, but that New Zealand teachers are experiencing greater demands.

Organisations tend to focus more and more on product and process development to increase their competitiveness. Several major organisations, among them ABB, have developed models aimed to more effectively control and manage product development processes. ABB is using its standardised model ABB Gate Model for this. The purpose of this thesis is to analyze how the introduction of ABB Gate Model has affected the outcome of decisions and also the decision-making in the product development process. The study is limited to elucidate the version of ABB Gate Model handling product development projects.

The use of temporary workers gives companies the opportunity to be flexible, by avoiding hiring and dismissing workers because of economic conditions and trends in demand. The management control in use at the company has the purpose of influencing employees? behaviour to act in the company?s best interest and towards its goals. The management control should also influence the behaviour of the temporary worker. The companies have to create motivation and commitment among the temporary workers although they are employed by a staffing agency.

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.

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.

Finns det någon skillnad i upplevd stress hos förskolepedagoger och grundskollärare? Stress hos lärare kan definieras som en känsla av ilska, spändhet, frustration eller depression. Enligt Krav- kontroll-stödmodellen mår de som har jobb med höga krav, låg kontroll och dåligt socialt stöd sämst på jobbet. En kvantitativ studie har gjorts där enkäter delats ut till lärare på förskolan och grundskolan i en mindre ort i Sverige. Data jämfördes sedan med data från en större ort i Sverige.
