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.

Sustainability issues have become increasingly high-profile and important in recent decades. In addition, quality issues have come to play a central role in corporate marketing, strategy and management. The word quality can be defined differently in different contexts. This paper focuses on the concept of quality, based on the Total Quality Management perspective, which in Swedish has come to be known as Offensiv kvalitetsutveckling. Offensiv kvalitetsutveckling has been described as a theoretical framework in which an organization continually strives to meet and preferably exceed customer needs and expectations at the lowest cost through continuous improvement, and in which all members of the organization are committed and focused on the organisation's processes. The purpose of this study was twofold. First, to clarify the applicability of the theoretical model Offensiv kvalitetsutveckling as a theoretical explanatory model. Second, to explore how Max Hamburgerrestauranger AB performs according to the values in Offensiv kvalitetsutveckling. A multiple case study was conducted in order to explore these topics. The results showed that Max Hamburgerrestauranger AB is working in a dedicated and value-driven manner, aligned with the values ??that form the basis for Offensiv kvalitetsutveckling. The results also showed that the model for Offensiv kvalitetsutveckling could serve well as a theoretical explanatory model, but that the model would benefit from being developed, enriched or integrated with other models.

Studies among parents of children with disabilities have shown that they experience a higher level of parenting stress as well as a lower degree of wellbeing, compared to parents of children without disabilities. However, there is a need to further explore parents? experience on this matter within a Swedish context. The aim of the current study was to examine how parents of preschool children, with and without disabilities, in Västerbotten, experience the impact of their child. A sample of 67 parents of children with disabilities and 134 parents of children without disabilities took part in the questionnaire study.

The purpose of this study is to examine the role social media canplay in a school library context, based on a theoretical model,called ?A new model for the public library in a knowledge andexperienced society? by Henrik Jochumsen, Dorte Skot-Hansenand Casper Hvegaard Rasmussen.The bachelor thesis aim to answer three research questions, theyare as follow: Which request of social media is there by teachersand pupils at a high school library? Which social media is the mostrequested by teachers and pupils at a high school library? Andshould the library services for teachers and students be improved ifsocial media were used at a high school library?The methodology used for this study was an inquiry investigation.My findings are presented in a context of previous, relatedresearch and the study shows that teachers and pupils are wellinformed of what social media is and they use social media whenthey are at school.The thesis also shows that the unit I study, a vocational trainingunit, is more or less interested in what the school library can do forthem with social media.They seldom are at the school library and they seldom use theteach platform were they can find library services.This result can open up for the school library to meet the users at anew arena with for example social media..

The purpose of this study was to examine how people experience being in debt, what they consider was the reason for being in debt and how they experienced economic counselling. The empirical data was based on five semi-structured interviews with people having experiences from being in debt and experiences of economic counselling. The data was analysed by using theoretical perspectives from a model called economic-shame created by Bengt Starrin. The model shows how being in debt and the feelings of shame influence health. The conclusion shows that the reasons for being in debt often is due to several sudden and tragic events happening at the same time or due to each other.

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 aim of this qualitative study was to investigate the social identity of students at upper secondary school for physically disabled students. The youths I drew my attention to suffered from severe physical disabilities and therefore received specially adapted education in small classes, but integrated at an ordinary upper secondary school.By "social identity" I mean how the students view themselves as a group, how they value their membership of the group and how they relate to non-disabled students at school. I wanted to investigate the connections between these students' social identity and the problems of marginalization of disabled people in society.According to qualitative methods I interviewed five physically disabled students, aged 18-19, at upper secondary school level taking part of especially adapted education. The study showed that these students regarded themselves as a segregated group at school. None of them associated with non-disabled students at school.

In this study I have explored the profession sales people and how they use social media. I have also studied their needs for further education and how it can be addressed in social media, in order to learn how a B2B-company that educates in sales training can meet sales people in social media. It?s an empirical study based on individual interviews with a semi-structured interview template. Respondents were of mixed age, both men and women.

I detta examensarbete undersöker jag två övergripande frågeställningar gällande fysisk tillgänglighet. Den första frågan rör varför enkelt avhjälpta hinder, det vill säga retroaktiva krav på ökad tillgänglighet, har tillfogats Sveriges bygglagstiftning. Den andra frågan rör hur arbetet med åtgärdandet av de retroaktiva föreskrifterna har utförts i svenska kommuner. Motiven bakom uppkomsten av krav undersöks genom en genomgång av äldre byggregler och handikapputredningar. I undersökningen konstateras att tillgänglighetskrav har funnits i svenska byggregler sedan länge, men att omfattning och formuleringar har varierat.

Personal assistance from a welfare perspective, offering a variety of reasons is perceived as a different design assistance than is usually there in the public social assistance depending on the strong foundations of the handicap principle autonomy and influence is in terms of how, what and when the operation is performed. The aim of our study was to highlight the handicap principle influence and autonomy in the operation of personal assistance. It is intended both to illustrate the legislature's intentions and ideologues expectations and also to examine a number of managers and personal assistants experiences of the conditions that exist for realize these principles. In order to answer our purpose and our issues, we have chosen a qualitative approach. We have first conducted a literature review and secondly implemented six interviews with personal assistants and managers.

The purpose of this thesis is to examine how five public libraries reason about the use of social media in their day-to-day work. This thesis aim to answer three research questions: What is the libraries use of social media today? How do libraries look upon their own use of social media? And have the libraries formulated any goals about their use of social media, and what are their thoughts on this? The methodology used in this thesis is a content analysis of the libraries social media and a questionnaire interview which was sent by mail to all of the libraries involved. The theoretical framework for the thesis is a model developed by Jochumsen, Hvenegaard Rasmussen and Skot-Hansen.The results of our study shows that the room of meetings, from the theoretical framework, are the most represented in the content of the social media used by the libraries. The libraries find that social media is a good way to connect and communicate with their users, but they feel that the time they spend on their social media is not enough.Our study also shows that most of the libraries have not formulated any goals for their use of social media, and that they do not have any intentions to do so..
