In the end of the 80´s the area of system development moved into a new era. As a consequence many new methods and development models emerged which in many cases resulted in problems when choosing system development models and methods. As a result of these problems the today standardized modeling language UML (Unified Modeling Language) was created. UML is tailored to support many different types of projects. This is possible because of UML?s capacity to be adjusted and adapted to a specific company environment.The purpose of this bachelor thesis is to investigate how and why companies use UML and what experiences and opinions those who use UML have of using UML in practice.

The thesis research problem is:- Which valuation methods does a valuator use in practice todetermine the value of producing companies and servicecompanies?- Does the valuator take different types of information andkey ratios in consideration when valuating producingcompanies and service companies?Purpose: The purpose is to examine and describe which valuation methods a valuator uses to valuate producing companies and servicecompanies in an acquisition.Method: In order to achieve the purpose of the thesis a quantitative survey and three qualitative interviews, made by email, has been carried out.Conclusion: The conclusion of the thesis is that discounted cash flow and relative valuation are used to determine the value of producingcompanies and service companies. The valuators choice ofvaluation method is not generally affected by the nature of thecompany?s operations.Keywords: Company valuation, valuation methods, producing companies,service companies, relative valuation, discounted cash flow.

Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

The aim of this thesis is to make a contribution to the field of design oriented theory, regarding young children and their way to digital competence. My research question is: How can a preschool with a certain pedagogical ICT-design give the children affordances for media play and for developing a digital competence?The European Parliament points out digital literacy as one of the Key Competences for life long learning. A digital competence is built on basic ICT (Information and Communication technology) skills. Skills you can develop any time during life, weather you are young or old.

Communication is an important part of any multi-agent system. There are different ways of communicating and they have different effects on a multi-agent system. This project describes and evaluates two different ways of communication, implicit and explicit. To compare the two methods, two experiments have been executed. The result of the experiments have been compared and discussed.

This work is about the rights of children, how students use social media and how effective teachers are using social media in their work against abusive treatment. The purpose of this work is to examine what students have rights in school, what and how students use social media and how schools and teachers are working to prevent the abuse that takes place over the internet and via mobile phones. The method used to investigate this is partly a survey of students in grades five and six at four different schools and interviews with four practicing teachers, working as a teacher in each class who made survey. My conclusion is that children have a variety of rights in school, and all schools and teachers are working on this through rules, values ??clarification and collaborative exercises. More and more younger children use out of social media, the survey shows that many of the students in grades five and six uses much social media.

The Civil Engineering office in Skellefteå needs to develop the users' participation in the planning of parks and playgrounds. In order to get such a procedure to work one have to find a method that can work in the daily activity. My work aims to find such a method and to implement it in practice. Apart from helping the Parks departement to find an functional method I will also develop a deepened knowledge about users?participation wich can be very useful i my future profession. This work can be divided in three stages.

The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy of this kind of low-height photographing system, a task given from the consultant company WSP, in Sweden. Landbadet in Uddevalla municipality was chosen as a test field for the zeppelin. Seventeen images distributed over three strips were acquired from the flying height of 80 m.

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.

My point of origin concerning this thesis was an interest for how school may develop students? reading comprehension. International surveys show that the results for Swedish students? performance regarding reading comprehension have declined and the current curriculum, Lgr-11, emphasizes the importance of incorporating this into all school subjects. The special teacher education programme has raised the awareness concerning the importance of including the students and that learning is achieved in an interactive setting.

 This study aims to deepen the understanding of which opinions and perceptions the teachers in the study have about the national goals, as well as local, when they plan their lessons in science studies for the younger ages. We wish to illustrate which goals these teachers find most important, their opinions on how they use these and how the different goals affect their design of teaching. The study also aims to examine which syllabuses, national or local, the teachers believe have an effect on their planning. Data were collected by interviews with four teachers, combined with questionnaires sent to 25 teachers teaching in science studies in forms 1-6. To analyse the data, key terms from Vygotsky and a sociocultural theory was used, such as situated learning, artifacts, the zone of proximal development, thinking in group and mediation. The data was also interpreted and examined by recent studies regarding this subject. The results show that the teachers find their own knowledge, the national syllabus and their colleagues as most important for their planning.

Humans and dogs are both mammals. One of the differences between the two species is that man walk on two legs and dogs on four legs. There are also differences in the nerve system between the two species. The human nerve system is supposed to provide opportunity for fine motor tasks- while the nerve system of the dog is more focused on the ability to perform locomotor tasks. Humans need to increase their motor control and postural control when affected by various conditions and diseases.
