In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

 There is a lack of research in the field of quality improvement efforts based on profound knowledge in social services. The current situation is therefore a significant knowledge gap in terms of studies of this type of systematic quality work and how it is applied in practice. This study therefore intends to describe Pilbackens quality work and further examine if the profound knowledge is consistent with quality work in microsystems by an analysis of Pilbackens work. The present study has been performed by a qualitative method and the material is collected through semi-structured interviews. In order to analyze the study?s result have profound knowledge and the model microsystems been used.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..

Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

This paper is a qualitative study of the pedagogical conditions and the knowledge necessary for the creation and development of an education regarding leadership in the field of amateur theatre.The purpose of the study has been for participants to reflect and create knowledge about the creation and implementation of a course for leaders of amateur theatre.Questions raised in the study concern the students? previous experience of drama, theatre and leadership; their desire to become leaders of theatre; their own view of their need for knowledge for their future leadership; their understanding of the contents of the education and the theoretical perspectives upon which a course in theatre leadership can build. Finally, the participants? perceptions of difficulties and possibilities of working as theatre leaders were investigated.All 13 participants have answered a questionnaire regarding their previous experience of drama, theatre and leadership and also about why they want to become theatre leaders. The participants have also taken part in four focus conversations regarding what they think they learned, how they value the knowledge they gained and what knowledge they feel will be needed in a future leadership.The data has been analyzed hermeneutically to find patterns in the participants? perceptions of their learning.

This study is based on an interest in trying to understand what is needed to ensure that students actually learn in a learning object, in this study equations. Algebra is an area of mathematics in several studies proved to be a stumbling block for many students. Using letters in mathematis is difficult for most students according to research reports and it is also consistent with my own experince as a teacher. The purpose of this study was to seek answers to what in the lesson content and also during the interview that allowed the students to learn more about the learning object. Based on students' prior knowledge and the difficulties students might have with the learning object and the offer of learning, I try to get an answer to what might have contribut the students to developed knowledge of the learning object.

The purpose of this study is to understand school counselors knowledge and work with cyber bullying among students. Our study is based on the result from eight qualitative semi-structured interviews. These interviews were conducted with school counselors working at elementary and high school in the state of Kronoberg, Sweden. Our theoretical base is human services organizations, street level bureaucrats and acting space. Our study shows that school counselors have adopted cyber bullying in various ways which has an impact on their knowledge and systematical work regarding this question.

Our purpose is to analyse three different epistemological discourses that exist in the social practice, Library and Information Science LIS, using the strategy for interpretation from the mimesis model by Paul Ricoeur and the terms from the critical discourse analysis by Norman Fairclough. The aim is also to explore there different views of knowledge organisation. We review previous research involving epistemology, knowledge organisation and discourse analysis in LIS. These show that there are many different epistemological standpoints and that later research has shown a more critical and sceptical state of knowledge organisation than earlier traditional positivist ideals. Discourse analysis is described as an important theory and method in LIS.

If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.

Linjäriseringar av olinjära system är mycket relevanta eftersom det finns en i förhållandevis enkel och omfattande matematisk teori kring linjära system, till skillnad från allmänna olinjära system.För vissa olinjära system är det svårt eller inte ens möjligt att genomföra en analytisk linjärisering.Orsakerna till detta kan vara hög komplexitet av systemet eller avsaknaden av ett analytiskt uttryck.Numerisk analys kan vara en lösning på detta problem.I detta examensarbete används framåtdifferens och centraldifferens för att genomföra de derivata-approximationersom behövs för att genomföra en numerisk linjärisering av ett olinjärt system.Rapporten behandlar även vad som sker då det är dålig upplösning på den indata som används när man genomför enlinjärisering, vad som händer med heltal och binära signaler om de ingår i ett system som linjäriseras ocheffekten av att ha olika samplingstider för olika delmoduler i ett system som linjäriseras.Slutligen undersöks numerisk bilinjärisering av ett system på bilinjär form och en jämförelse mellan analytisk linjärisering och bilinjärisering görs..

Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad. One of Banverket Trafiks information systems (Opera) presents the train?s actual position on a map and provides the user with physical information about the trains. Due to increasing demands on the information systems, Banverket Trafik needs to update the present system architecture in order to manage the increasing demands on map graphics and map functions. This paper analysis the information system Opera on the basis of theory and support of methods and discuss problems and demands for Opera.

This survey aims to investigate and analyze how six teachers on a high school in Stockholm reflect on pedagogical aspects of problem based learning( PBL). The survey focuses on ana-lyzing how the teachers relate to the benefits and problems of PBL and how they reflect on the students development. The survey was conducted on a high school and the method used for the study was interviews, each taking 30-45 minutes. The outcome of the survey indicates that the teachers sees problem based learning as an alternative to what they define as tradi-tional education regarding its epistemology. They indicate that PBL allows the students to define their own questions, to be carriers of knowledge and to evolve analytic skills in relation to the basegroup.

This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system.
