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 health care system in most western countries is undergoing rapid changes with an increasing amount of people living with chronic cancer. These people have to deal with their disease in every day life together with working and family life. The relationship between health services and every day life has changed and raises new requirements. Earlier research has shown that maintaining every day life is important for cancer patients and their families. This study comprised patients with lymphoma receiving their diagnosis during 2003 ? 2005.

In this textual analysis I have examined the book Att följa Jesus by Ulf Ekman and information from Word of Life's official website. The aim of this study is to see how a religious leader is shaping the identity of the groups members after a certain pattern that differs from the surrounding, secular society. The research focus  of this essay includes several aspects:  how a culture is formed in a religious minority in contrast to the prevailing cultural context; how the material can be explained by Paul Pruyser?s theory on the psychological worlds; how what Ulf Ekman writes about distinguishing themselves from the environment differs from how other religious minority groups distinguish their identity;  and,  how the psychological world, expected behavior, and context of Word of Life can be structured by Valerie DeMarinis? model of assessment. I have placed Word of Life in a realistic illusionistic world developed from Paul Pruyser?s theory of psychological worlds.

The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.

This project aims at investigating if the use of UML as a support to small-scale development ofan embedded system is relevant. The investigation is conducted by using UML during the initialphase of the development ofTelfafill, a filling machine by the company ?Telfafill AB?. The aimof the development of Telfafill is to separate the user interface from the control unit. In additionto this main objective, Telfafill AB would like possible changes to, and additions of,functionality of the filling machine to be investigated.Within the boundaries of this project, the development of Telfafill reached a full requirementspecification of the proposed system, and contact was made with potential external developers.No prototype construction had been started when the project ended.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

The aim of this study was to investigate if behaviour, ear positions and cortisol in lamb which were given access to play followed the different phases of the reward cycle of anticipation, consumption and relaxation. The study was done on 8 Dorset and 12 Dorset x Fine Wool uncastrated male lambs with an average age of 10 weeks. The lambs were housed pairwise in litter pens (2 x 3 m). Pairs of lambs were taken to a play arena (5.9 x 5.5 m) three times a week during five weeks (first week for learning). They were then first kept in a holding pen where they could look into the play arena for 5 minutes and thereafter released for 20 minutes in the play arena which had a ball, two chains and a tunnel.

Parallel to new technological advancements, including the development of interactive recommender systems, digital music services on the Internet, such as Spotify, have in a short time span gradually replaced former physical media such as CDs and MP3-players and become pioneers on a market with an otherwise uncertain future. By subscribing to the service, users have access to a vast library of music and from any device with Internet access. In order to provide a satisfactory and useful musical experience, different ways of coping with the vastness is required - which is precisely what recommender systems are for. Improved filtering techniques and use of devices built in sensors, make way for new opportunities of more precise and contextually tailored suggestions for track selection, which in turn leads to potential privacy issues when using interactive music services. But where do we stand today? By compiling, exemplifying and discussing three different perspectives with relating to the development of interactive music recommender systems, the objective for this paper is to provide a for science, industry and user, objectively nuanced account of current potentials and expectations.

The purpose of this master thesis is to, with the strategies of the organization and the preferences of the co-workers in mind, explore how reward systems can be designed in heterogeneous organizations. This is done by interviewing store managers and sales personnel in a heterogeneous organization. The frame of reference deals with theoretical approaches on reward systems and is divided in the following sections, individual or group based, differentiated or not differentiated rewards systems and goals, measurements and rewards. These sections are highlighted from the following aspects, equity, implementation possibilities and finally environment. The theoretical discussion ends in the conclusion that heterogeneous organizations should have several different reward systems, but not if a restructuring process is in progress or the system becomes too costly.

Visualization is a rapidly growing area of computer graphics. Due to the very progressive development of computer technology and especially 3D-graphic boards yesterdays imagination of visualizations, today is a reality. At Saab Bofors Dynamics in Linköping missile systems are developed. Through the development, different subsystems are simulated before the manufacturing starts. The results of these simulations have to be visualized to get a meaning.

The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

This study has been conducted on behalf of Vectura Consulting AB with the purpose to examine how different actors perceive the dimensions of sustainability and sustainable construction. The purpose is also to provide an understanding of existing barriers and opportunities for sustainable construction within the industry and exemplify with different directions for the actors in order to develop sustainability. The study has approach the research problem by using systems theory, developed by Checkland, to identify the relevant system. Other systems theories has been used as an theoretical framework in order to identify barriers and opportunities, which in this study are based on Hughes?s theory about reverse salients and salients.

Personal trainer is a profession that has grown strongly in recent decades, and has become increasingly common in the labor market within the health sector due to the widespread and growing interest in health and self- improvement. Further more, personal training is a great example of occupations with a close interaction between producer and consumer. The purpose of this study was to examine whether and if so how, personal trainers experience that the relationship with the clients affects their own personal development. This by finding out what impact the profession has had on the personality, what impact the relationship with the clients has affected the leadership, and last what impact the relationship with the clients have had on the personality based on social and mental aspects. Based on the purpose of the study qualitative method was chosen and data was collected with qualitative interviews.
