Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

The process of value creation is rapidly shifting from a product- and firm-centric view to personalized consumer experience today. Informed, networked, empowered and active consumers are increasingly co-creating value with the firm. The interaction between the firm and the consumer as well as the experience factor plays an increasingly important role in determining the success of a company?s offering. In this study, a special type of co-creating experience is investigated - ?omstartspex? - where the audience is interacting with actors during the play.

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

This paper examines and analyzes effects of the introduction of a new management control system tool within a Swedish public health organization, the Södra Älvsborg hospital, and its possible effect on organizational change. The new management control system tool, known as the SÄS-model, has been widely criticized for being too costly and with too small positive effects to be shown. Our approach has with that as a background been to examine whether the implementation of the SÄS-model and its balanced scorecard has been able to result in effects regarding organizational change. We have through a case study aimed to analyze how a management control system, much alike one that is typically used within foremost private organizations, can promote organizational change. Our results suggest that the implementation of the SÄS-model and the balanced scorecard has given the organization clearer visions and goals.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

Today´s debate in farming is being focused on tourism, outdoor life and hobbies in the rural areas. This is of interest also for the general public as a way of counteracting the depopulation of the rural areas. Within the last years, the farming has become more technically advanced and hence efficient. This has led to increased production volumes and wider selection of products with lower margins for the farmer as a consequence. When the profitability is reduced, the farmer is faced with the choice of either increasing efficiency or diversification of the business.

Sweden is a world leader in listed private equity and ranked fifth in the world in market capitalization. The sector is attracting increasing interest from the investment community. However, the private equity industry in Sweden has historically poor reputation and is criticized for creating value through high leverage, multiple riding and severe cuts. This study analyzes value creation drivers in buyouts from the perspective of the private equity firm using a dataset of 15 realized buyouts by private equity firms listed on NASDAQ OMX Nordic Stockholm. The methodology used separates the value contribution of leverage on the private equity firm's return from internal operational improvements and external variations in transaction multiples.

This essay examines how the meaning of an absurd play may be affected by how the reader understands the text. To address this problem I have turned to Wolfgang Isers theory of reception. Primarily I have taken on that the creation of meaning comes about when the reader fills in blanks in the text. I have also used Martin Esslins work on the theater of the absurd. I have mainly studied his research on Harold Pinter.

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

The aim of our graduate work is to study the importance of image and shape?s in children's development and learning and also the preschool teacher?s views on image and shapes. Our research aims to explore the value of image and shapes creation and how it is expressed among children and in classroom activities. We are also interested in finding out how it differs from adults' views and what materials teachers use to promote the image and shapes creation in the curriculum. In our own experience, image and shapes activities are often structured differently in different curriculum activities.

The aim of this study is to obtain a deep knowledge about identity creation of preschool child-ren at the age of four to sex with creative pictures and its aesthetic learning processes with childrens perspective as a starting-point. The issues that I have used in this study are how childrens identity creation relates to the aesthetic learning processes in the preschool enviro-ment, how children experience the figuration of their own identity related to other individuals and the enviroment by taking different positions in aesthetic learning processes and how childrens identity creation becomes visible in preschool.In order to explore preschool childrens identity creation in aesthetic learning processes the qualitative research-oriented approach has been implemented with unstructured observations and the informal interview as the methods for data acquiring.This studys theoretical points are sociocultural perspective and symbolic interactionism. Both these theoretical perspectives emphasize the significance of communication, taking different perspectives and learning in an interaction between an individual and enviroment within given sociocultural frames of referens which results in an individuals identity development.Results from the study show that childrens painting is more than an occupation with a picture as a product. Childrens painting is rather a playfull aesthetic expression form and a relation-oriented, dynamic learning process which is related to the enriching of individual self, the consciousness and the creation of meaning within preschools frames of reference.My expectation is that my study will contribute to didactic discussions about childrens iden-tity creation while using aesthetic expression forms..

Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.

This study is generated from a European Union project founded Barcelona, Spain and contents a questionnaire that is the same in the different studies, but with different questions or thesis in each of them. Our question is if there is an identity creation in the meeting with other people and if so, how that identity creation is constructed. The identity-creation-meeting in the study is a fictive love relation story. Two high school classes in the Stockholm area have participated in the inquiries.The work of Bjerrum-Nielsen & Rudberg (1991) shows that the two sexes differ in their opinion about what is desired in a relationship. The result of our study points out that both young men and women mostly prefers the same qualities in a relation in spite of that gender socialisation directs the informants towards stereotypical roles.
