AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

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.

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

The purpose of this study is to investigate how students in a Swedishjunior high school (grade 7-9) view their possibility to participate in thecollection management of their school library, and how the schoollibrary works to involve the students when purchasing media. The studyhas resulted in a model for easy and effective involvement of studentsin the collection development.To achieve this aim both quantitative and qualitative methods are used.A survey in three classes in the school, observations at the schoollibrary and a qualitative interview with the library assistant have beenperformed. The collection management at the school library isdescribed using the School Library Taxonomies developed by DavidLoertscher and two models for participation developed by Roger A Hartand Harry Shier. In the survey, the students are asked about their libraryand reading habits, their perception of their own participation in thecollection management of the library and their opinions of theimportance of student participation in the library.The results show that all students view the possibility of participation as something important, but not all of the students are willing to be active themselves. The proposed model for effective involvement of students in the library focuses on simplicity, voluntariness, distinct information and visible results..

This essay examines how the meaning of an absurd play may be affected by how the reader understands the text. To address this problem I have turned to Wolfgang Isers theory of reception. Primarily I have taken on that the creation of meaning comes about when the reader fills in blanks in the text. I have also used Martin Esslins work on the theater of the absurd. I have mainly studied his research on Harold Pinter.

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

This bachelor thesis describes the process of developing a two wheeled robot with activebalancing. The robot is designed to go straight ahead until it reaches a finish line. Then it shallstop to stand still balancing. The workload in the group has been divided according to theprevious individual projects, which are attached. The design of the robot is inspired by theconcept of the Segway.

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.

Hospital Mergers have been proved to be troublesome, the most crucial ingredient is believed tobe the participation of members of the organization on all levels. When the hospital mergerbetween the hospital of Malmö and the hospital of Lund is a fact, it seems clear that knowledgeabout managing motivation is important. The knowledge could also lead to increased possibilitiesto improve support for motivation where needed at the hospital.I have through a literature review created a descriptive model of the theoretical view onmotivational factors for participation in change and their relationships. The theoretical modelwhere then tested in a empirical study in which additional data created a more true model of themotivation on participation at the hospital.The findings of the study show how the descriptive model illustrates how the twodifferent departments both work with a empowering philosophy that have built in properties thatenable the employees to gain more motivation. The model also underline the importance of thecommunication role to enlighten the employee in what, where, when and why the change takesplace.

This project consists of an adaptation, trial and evaluation of a model for practicing. Based on prior research I created a model aiming mainly to raise a musician?s self- awareness around the different parameters a performance consists of. An additional wish was for it to simultaneously assist the musician in monitoring his or her progress. With video recording and self-evaluation as the two main parts I tried the model by using it over a period of three months.
