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.

AbstractThe purpose with my study was to find out how students with physical difficulties are treated in school by teachers and other students and also if there are any differences between how teachers and students treat students with physical difficulties. I also wanted to see if there were any prejudices against students with physical disabilities from either students or teachers. If there are any prejudices, I wanted to know what kind it is that exists. When I went to school, I remember that I looked down on the students with physical difficulties because they were different. When I have been working in school as a teacher, I have seen students who pull away from students with difficulties.I chose to do the study at a higher grade school, because I have not been in such a high grade in school during my practice.

Aim: To investigate if physical exercise in combination with coaching will reduce pain and improve knee function in patients with mild to moderate osteoarthritis in the knee compared to physical exercise alone.Method: The study consisted of 42 patients who were randomized to either an intervention group or a control group. Both groups followed a standardized training program at home, but the intervention group received additional support with regard to the aim of their training, as well as extra coaching during the training period of ten weeks. A Visual Analog Scale (VAS) was used to evaluate the patients? pain. A 10 metre walking test, the Index of Muscle Function (IMF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) were also used to evaluate knee function.

This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..

Rapporten var en systematisk litteratursammanställning. Databaserna som användes för sökningen var AMED, PubMED och ProQuest.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

Introduction: Each year 1200-1300 patients are diagnosed with head neck cancer. Treatment that involves radiotherapy can cause severe side effects for example trismus that affects quality of life.Purpose: To study health-related quality of life in patients who have undergone radiation treatment for head and neck cancer and participated in a intervention group who received training intended to prevent trismus or in a control group who received standard treatment.Method: This is a prospective study in which data is collected from 66 patients participating in a randomized study aiming to evaluate a training program to prevent trismus. Thirty three participated in the intervention group and thirty three in the control group. Both patient groups assessed health related quality of life (HRQOL) with EORTC QLQ C30 and QLQ-H&N35, at start and end of the radiation treatment, and at 3 and 6-months after completing radiation treatment.Results: There is no difference between the intervention and control groups regarding symptoms, functional status and global health, except for intake of nutritional supplements.  For both groups almost all scales measuring HRQOL deteriorated under the radiation treatment. However, 3 and 6 months after end of radiotherapy HRQOL had improved and had returned to the baseline values.

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

The aims of the present study were to implement and evaluate a three-session Acceptance and Commitment Therapy (ACT) stress management intervention in a non-clinical group of university students (N = 25) and to investigate the importance of practice in an ACT-intervention. A design with pre-test and double post-test was chosen. A comparison was made between a nine-hour ACT-intervention containing practice for the participants, a two-hour lecture on ACT and stress management containing no practice for the participants and a control group. Psychological flexibility was assessed with Acceptance and Action Questionnaire-2 and mindfulness was measured with Kentucky Inventory of Mindfulness Skills. Perceived stress level was measured with Perceived Stress Scale.

Purpose: To evaluate how a treatment period on four weeks in a warm climate influences physical function, condition and the patient's experience of the climate effect of patients with ankylosing spondylitis. Method: 10 persons with a diagnosis of ankylosing spondylitis went through four weeks of treatment on Centro Forestal Sueco, Marbella. The treatment consisted of both physical and theoretic lessons given of a rehabilitation team. All patients were examinated measured for physical function and condition before treatment, after two weeks and at the end of the treatment. To measure physical function, Timed-Stands Test, Timed Get Up and Go, The Bath Ankylosing Spondylitis Metrology Index, Index of muscle function and functionestimitation of shoulder/arm were used.

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.

Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.
