Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

This report represents a comparison between two different tools used to create an online store that was developed by two students at the Technical University in Jönköping. The web shop will be of great benefit to both customers and administrator in a food firm known as Mattias' Livs. The company wanted an online store that facilitates the sale section and gives a full control of their stocks. The aim of this thesis is to create an online store that offers customers the ability to shop online and help the staff to operate the company in a simpler and more efficient way, which reduces the need for human resources and thus leads to less costs for the company. The aim also includes a comparison between the two different tools used to create the online store.

This bachelor thesis discusses various difficulties with architectural paint research. The difficulties are exemplified through a case study ? a paint research on a furrowed string-course in the southern vault of the Royal Palace of Stockholm, which was carried out November ? March 2009-2010 on behalf of Statens Fastighetsverk. The paint research was made in order to receive information about the string-course and to get inspiration for a renewed color scheme on it. The base material of the string-course is Gotlandic sandstone and the surface of it is furrowed.

For a company to survive it has to make a profit. To make a profit transactions are necessary and to achieve this a company can choose to focus on creating loyal customers. Loyal customers can contribute to secured revenues, increased market shares and reduced marketing costs. Research within customer loyalty has mainly focused on different types of loyalty and the impact it has on customers behavior. However, there is a lack of research concerning which factors that create loyal customers.

Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..

Title: Theory and Practice: A study of Swedish Research on the Internationalization in Swedish Business and its Relevance to Practice´s, according to The Camber of Commers, Swedish Trade Council and researchers.Main issue: Within marketing science, there is an general ongoing discussion about the gap between researchers and practitioners, this leads to the thesis main issue on whether the Swedish marketing research conducted in the internationalization of Swedish companies, is relevant to practitioners and provides essential tools for practitioners to applicable in real business situations.Purpose: The purpose is to answer the problems of theory and practice, what it looks like and what the underlying factors and impact difference between internationalization theory and practice are.Method: The thesis has a qualitative methodology mainly based on theory, as well as empirical findings from researchers and organizations working with Swedish company's internationalization.Results: The result shows that there is a difference between theory and practice and that there are several factors underpinning this. Theories primary purpose is not to be practical but to explore an unanswered need to create an understanding to the researcher?s audience, which is other researchers, thereby are theories based on knowledge not demands from the practitioners. The result also shows that the internationalization theories can be applied in practice´s reality on the internationalization of companies. Research degree of generality has a sense of reality given by the empirical studies which therefore reflects the reality of the theory which gives theory a content of truth.Conclusion: The gap that exists between theory and practice has both positive and negative effects.

The object under investigation in this Master?s thesis is students? information use in connection to Bachelor thesis writing. The purpose of the study is to increase understanding of why nursing students and product engineering design students are using information in such different ways despite their comparable starting point. The empirical material consists of 18 student theses and a document comprising directives for thesis writing that are analysed from three different theoretical perspectives. A citation analysis of all 18 theses is carried out.

Background: Many authors consider knowledge to be a significant source for competitive advantage. Replicating companies found their competitiveness on an ability to leverage its knowledge base by replicating its business model in new contexts, a process often referred to as the McDonalds approach. Several authors emphasize that an efficient method for knowledge transfer may increase the risk for imitation. Purpose: The purpose of this study is to examine in an explorative manner how strategies for replicating complex knowledge systems are employed and developed. Furthermore, our ambition is to explore the notion of replication strategy.

The aim of this essay is to analyze how media constructs strategic positional statements in debates of great immediate interest in order to stress ideological standpoints. Two questions are derived on the basis of this aim.- How is Russia positioned in Svenska Dagbladet's and Dagens Nyheter's editorials in the debate on the Swedish defence during 09-01-13 - 09-01-31?- Are there differences in the positional statements between the newspapers?In the study a Critical Discourse Analytical (CDA) approach is applied, and more specifically that of Teun A. van Dijk. Both the theoretical basis and the methodological tools are based on van Dijks CDA.

Issues related to multilingualism and its importance to each individual and the whole society are the subject of today?s school debate. The mere fact that the aspects of multilingualism are discussed actively not only in a school environment but even in the mass media and other communities proves that multilingualism is an important and complex phenomenon in our lives.The subject that I have chosen to study into is about the importance of multilingualism for minority individuals and the conditions for their multilingualism. The aim of this research is to investigate the importance of multilingualism for identity formation among several Russian-speaking young people who were born and raised in Estonia, as well as to try to understand the factors that were relevant to these young people's multilingualism and their view on it. Six young people aged 16-19 were considered in this study.

The purpose of this study is from a case study develop a model that aims to cost effectively improve productivity in a manufacturing production process. The study highlights the importance of having knowledge about customer needs and using a holistic process perspective when improving productivity to identify the relations between the process stations and by this find problems that cause waste and losses in productivity. Tools and methods used to make production more efficient such as single minute exchange of die, spaghetti diagram, 5s and master production schedule is presented an applied in the model to see how these effect costs, productivity etc.Maintenance effects on quality and productivity in a manufacturing company will as well be covered in this thesis. The results and conclusions finally reveals how the process improvement tools, maintenance and production planning for example effects each other and why it is important to establish an attitude in the company where continuous process improvement should be emphasized..

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.

The purpose of this Masters thesis is to analyze the research front within medical ethics. We wish to identify which research themes that are included in the subject field of medical ethics. The research themes can be identified by a couple of bibliometrical methods and techniques. In our case, it is bibliographic coupling combined with a cluster analysis. The analysis is accomplished by the extracted references from articles in the two journals Bioethics and Journal of medical ethics.
