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.

Background: Studies showed differences in attitudes towards patients with mental illness in nurses who worked in somatic care compared to nurses who worked in psychiatric care. The nurses in somatic care stated more negative attitudes to mental illness in relation to the nurses in psychiatric care. Studies also showed that work experience affected attitudes towards mental illness. Nurses who often came in contact with people with mental illness had less negative attitudes and prejudices against mental illness. Aim: The aim was to examine the experiences from nurses in somatic care, caring for patients who also have a psychiatric diagnosis.

Background: Mental health problems among children and adolescents have increased. The school is an important arena for prevention of mental health problems. There is a huge demand for successful interventions. SEL is a method that aims to increase the social and emotional competence among children and adolescents. The program SET applies this method.

Syftet (även kallat huvudtema i kategoriprofilen) med studien var primärt att (1) undersöka vilkeninställning idrottande ungdomar har till begreppet mental styrka. Sekundärt syfte som förs upp tilldiskussion var att (2) skapa en förståelse om hur de tränar och upprätthåller sin mentala styrka samt(3) vilka faktorer under träning och tävling som deltagarna anser är viktiga för att utveckla ochupprätthålla mental styrka. I studien deltog tio idrottande ungdomar (m= 16,24), 6 män och 4kvinnor inom både lag och individuella idrotter. En egen utformad semi- strukturerad intervjuguideanvändes, utvecklad med teoretiskt stöd från Jones et al., (2007) och Gucciardi et el., (2009).Resultaten i studien visade att deltagarnas inställning och kunskap om begreppet mental styrkavarierade. De flesta deltagarna hade en positiv inställning och ansåg att det var en viktig faktor i deflesta situationer inom deras idrott.

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.

Patients with mental illness experience dissatisfaction with their care due to lack of understanding and ignorance from the nurses. The nurses? approach might influence these patients' experience of their care. The purpose of the literature review was to describe nurses' approach in care of patients with mental illness. The literature review is based on an inductive approach and the result is based on 14 scientific papers, of which eight used a qualitative design and sex used a quantitative design.

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.

Subsurface Scattering är nu för tiden väldigt populärt inom datorgrafik och används inom de flesta filmer och spel, men det är ingen enkel process för att uppnå ett bra resultat. Därmed kommer forskningen och utvecklingen fokuseras på subsurface scattering i verkligheten och inom Autodesk Maya med inbyggda renderingsmotorn mental ray. Subsurface scattering via mental ray kan lösas på flera olika sätt och nödvändig information om subsurface scattering shaders och andra noder kommer att förklaras för de metoder som känns till som lightmaps och photon maps. Det kommer även finnas en tredje metod som fokuserar på passrendering av en lightmap shader. Metoderna bevisar sedan vilken metod som anses vara den bästa för situationen man befinner sig i..

Suicid har minskat i Sverige de senaste decennierna men ändå är suicid den vanligaste dödsorsaken bland män i åldersgruppen 15-44 år och bland kvinnor i samma åldersgrupp är det den näst vanligaste dödsorsaken. ....

Mitt arbeta handlar om mental träning för elever som känner sig stressade inför prov. Då mina erfarenheter var begränsade inom området, valde jag att anpassa ett redan utformat material inom idrotten, Integrerad mental träning (IMT, 1996), skriven av Lars-Eric Unesthål. Här ändrade jag endast på vissa formuleringar för att materialet skulle passa in på skolan. Arbetet består av en teoretisk del utifrån idrotten och en teoretisk del där jag visar på vad mental träning kan åstadkomma i skolan. Till sist finns en praktisk del, med ett utarbetat åtgärdsprogram för arbete med mental träning i skolan.

The mental health has during the recent years decreased among Swedish adolescents while theinternet has become a common tool for communication between people. Aim: The overall aim is toidentify the relationship between internet use among adolescents and their mental health. Method:A literature based study within a defined research field. Result: The scientific hypotheses whichexist is based on whether social capital increase or decrease due to internet use. The healthoutcome is positively affected by internet communication, especially for boys and socially anxiousadolescents.

Abstract Integrated mental training is a method that entails a systematic and long-term training of mental processes (thoughts, images, emotions) that aims to enhance performance as well as gratify feelings and improve thought processes. This training develops an alternative system of control by using substitute state of consciousness and self-hypnosis. The method is concerned with both mindfulness and performance approaches, which is crucial in order to feel and function better. The intent of this study is to highlight the experience of the different steps of integrated mental training to gain an understanding of how, where, and when changes occur. To achieve the objective of this study, a qualitative empirical method was used.

Mental illness in school ? A counselors perspective - The purpose of the study is to examine school counselors work with students (13- 15 years of age) who are struggling with mental illness. Focus on mental illness is discussed in a school context. From the school counselors perspective questions like, what kind of working methods are they using and, how they collaborate are examined. The research design is based on a qualitative approach, with ten Semistructured interviews with ten different informants who work as a counsellor at 10 different schools around Skåne.
