Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Background: Ill-health related to unhealthy lifestyle is increasing and despite existing knowledge about healthy lifestyle it is difficult to change behaviour. Counselling in the primary health care is often superficial and without critical elements for behaviour change. Aim: The aim of this paper to elucidate interventions for change of lifestyle with respect diet and physical activity. Method: A literature review was carried out and ten scientific articles were analyzed and compiled in two main categories: design of these interventions and participation in them. Results: Education, decision making, goal setting, feedback, social support and follow-up were identified as critical elements for behaviour change.

Background: Poor perineal wound healing and infections after proctectomy surgery, affect a significant proportion of physical and psychological morbidities such as pain, leakage and abscesses. In its lengthening some of these symptoms will lead to extended periods of hospitalization. These kind of postoperative complications are also associated with delays in eventual chemotherapy treatment Aim: To describe the patients experiences of postoperative wound infection as well as communication and self-care support from the nurse specialist after proctectomy due to rectal cancer.

           AbstractAims: To explore whether and in that case how nurses question women in the psychiatric care about violence in close relationships and how nurses respond to women who have been exposed to domestic violence.Method: A qualitative descriptive interview study with twelve nurses from four psychiatric wards was carried out in Uppsala. Informants were chosen from a convenient selection. The interviews with semi-structured interview questions were recorded on tape, transcribed and analyzed with content analysis.Results: There is no routine to ask all female patients if they are victims of violence. It happens only in cases where the suspicion arises or is confirmed. It is individually whether and how the nurse asks the woman if she is subjected to violence in a close relationship, depending on patient and nurse.

The purpose with this degree thesis was to investigate the preschool teacher´s view onchildrens´s influence in preschool routine situations. The target group for this study ispreschool teacher´s that currently are working with children that are 1 ? 5 years of age. To manage to answer the aim of this study semi-structured interviews were conducted. I have performed interviews with five preschool teacher´s that currently work in a preschool that is situated in a medium sized city, in the county Värmland, Sweden.

My intention with this study is to evaluate, as a singer and a voice teacher, a number of routines for daily vocal practice through practical application. Seven different routines are presented, five of them originating from interviews with Swedish vocal teachers and singers and two chosen from literature. These routines are then tried out and evaluated. Using the results of these evaluations as a basis, I make an attempt at formulating my own personal practice routine, optimal for my own needs. I will also try to address motivational issues related to practice with hints acquired through the interviews.

Today, some kind of laboratory results is required for around 70% of the diagnostics and follow-ups for diseases. In many of the cases the time from sampling to a result is very critical. Therefore the discussion of how to improve this situation has begun. For many analyses serum has been the routine choice for a long time but now it is disputed. After blood collection in a serum tube it is essential to wait 30-60 minutes before centrifugation and analysis of the sample, a long time for someone in an acute state.

Background:The adult inpatient psychiatric care is regulated by law and allows certain amount of coercion, most commonly restraint, forced medication and seclusion. To be treated according to this law you need to suffer from a serious mental disorder, oppose to the care and have an indispensable need of care. Many studies describe patients experiences to be treated with coercion but few about health care workers experiences.Aim:To describe health care workers experiences of performing coercion in psychiatric compulsory care.Method:A literature review was made and eight articles is the basis for the result.Results:From the articles used inthis study four themes were created. These are coercions impact on relations, health care workers feelings during coercion, coercion as a necessary evil and health care workers need for reflection. The themes are presented as headlines in the result.Conclusion:To use coercive measures brings out many different feelings among health care workers.

Palliative care is founded on a holistic attitude, with the goal to alleviate suffering when a cure is no longer possible. Palliative care affirms life and regards dying as a normal process, providing possibilities of a quality time for the patient and family. Studies show that an increasing number of people choose to live the final phase of their life in their own home. A requirement for end of life care is an effective team work, where the nurse is responsible for more advanced care, and the caregiver?s provides the immediate care.
