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).

Outdoor education is a teaching method which has several advantages to traditional classroom tuition. Its ideas have a long tradition and find support in the current Swedish curriculum. The place for the tuition is a central aspect within outdoor education. This essay aims to investigate what good places for outdoor education look like as well as discussing how the characteristics of such places can be used when designing schoolyards. Previous research shows that nature has characteristics that suit outdoor education well.

Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).

 Date                   May 28, 2009Level                  Bachelor thesis in Business Administration/Information TechnologyAuthors             Jennie Andersson, Niklas Fridell, Visar HoxhaTutor                  Marie MörndalDepartment    HSTTitle                    ERP-solutions in small to medium sized enterprises ? possibilities and problemsSummary          ERP-solutions have penetrated the market for SME: s, offering the same advantages larger enterprises have enjoyed for years. For a significantly cheaper price, SME: s can nowadays acquire ERP-solutions and become more effective and increase their profit.  The authors have examined five SME: s in both the production and service company segment and have come to the conclusion that an ERP-solution would indeed benefit these companies in many levels but also induce certain obstacles the examined companies must overcome, both financial and organizational.Purpose            The purpose of this thesis is to examine if and how SME: s can become more efficient and developed and increase their profit by implementing an ERP-solution. Further, the purpose is to discuss which conditions that exists for the examined SME: s in order to implement an ERP-solution.Method            The thesis consists of a qualitative research where the authors have interviewed either the owner or employees at management level by using semi-structured interviews.

This master?s thesis was performed during the fall of 2006 at Cloetta Fazer AB in Ljungsbro. Cloetta Fazer is the market leader in Scandinavia of manufacturing confectionary and chocolates. The purpose of the project has been to identify causes that impact the quantity of waste in production as well as a cost/benefit analysis of the solutions that can reduce the problem of production waste.The work includes four production lines that are individually designed depending on what kind of product that are produced on the line. By using qualitative and quantitative methods such as focus groups, interviews and observations data has been collected.

The purpose behind this work was to investigate whether I could from a practical approach to create desire for mathematics among students in primary schools. I wanted also to find out how students feel about their current mathematics teaching. By introducing an equation game, and interviewing students to find out their perception of their mathematics teaching, I was able to answer my questions. What I came to was that through a practical and laboratory work, I could create an enjoyable educational opportunity in mathematics. Then during the interviews I also learned that students had not a pre-determined negative attitude towards mathematics.

Knowledge is today one of the most important resources for an organization to handle. But knowledge can also be difficult for organizations to manage. The internet is still growing and new tools take form that allows users to effectively share information. The purpose of this report was to describe how organizations can make use out of internal social media to facilitate knowledge management processes. Three issues involving mapping, coding and dissemination of knowledge to were produced to answer the thesis. The study was limited to examining the identification, coding and dissemination of knowledge through the internal social media plattformen, IBM Connections. The theoretical framework emphasizes how social networks can promote knowledge sharing, how a knowledge mapping can promote knowledge dissemination and sharing, how knowledge can be stored in data sources and how important interaction is to spread awareness. The theory has been supplemented by descriptions of how the system IBM Connections works. Surveys were conducted on four companies that use IBM Connections as an internal communication plattformen. The four companies were selected to illustrate how they use the plattformen of knowledge management processes and we chose to interview the people who were responsible for the introduction of the plattformen. The study identified several similarities between the different companies and that although there were some technical and cultural recalcitrant units against this new type of system within the organization so favored IBM Connections knowledge in several ways. The built-in search automatic created a map of knowledge through the plattform's user profiles. Saved files and documents could be found even after the employees left the company, which encodes knowledge into the company knowledge resources. The opportunity to interact with one another, often over great distances, favored the sharing of knowledge. A comparison with the theoretical framework provided us with the conclusion that internal social media can be used in several ways to Knowledge management through automated knowledge maps, the ability to store knowledge within the company and to communicate knowledge across functional and geographical boundaries in interactive discussions..

The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..

[ An abstract in English will follow]Denna uppsats handlar om på vilket sätt användarinvolvering påverkar acceptansen av ett affärssystem. I studien redogörs varför acceptansen påverkas av användarinvolveringen, samt hur påverkan sker och vad som leder till den.IT genomsyrar idag så gott som alla former av företagsamhet. Affärssystem stödjer affärsprocesser i flera branscher, från tillverkande företag till renodlade tjänsteföretag. Ett företag behöver exempelvis anpassa både sina affärsprocesser och det nya affärssystem för allt som sker inom företaget. På grund av komplexiteten som detta för med sig är implementeringen ofta ett stort steg för företaget och dess anställda.

This examination paper defines how educators work with esthetic, and esthetic learning in pre-school. I have done research by interviewing four pedagogues. The result shows that the pedagogues does work with esthetic and practice esthetic learning processes, but their work shift. Some pedagoues practice strong esthetic and some practice more modest esthetic. Some of the pedagogues are more aware than other of the esthetics influens of the childrens life long learning.

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.
