This thesis is an attempt to study computer games and playful computer programs for childrenand youth at Swedish public libraries. The main method used, is qualitative interviews.The main reason the libraries in the study offer computer games and playful computer programsto their users, is that every member of the society shall have opportunity to use newtechnology such as computers and computer programs. The users of this media are for themost part boys. The librarians in our study wish to have pedagogical games and programswithout violent themes at their libraries. Lending computer games and computer programs isnot of any priority for the libraries..

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

The purpose of this thesis has been to explore the topic of business simulation from a theoretical foundation in social constructivism and theories concerning leadership as the management of meaning. The most important findings are that business simulation can be used for strategical leadership by management to create a common vision in the organisation members, which affects their perception of the business and the decisions and actions they make, which in turn can lead to a more efficient organisation that becomes better at meeting set goals. This can be viewed in different ways from different theoretical viewpoints: as inducing targeted changes in mental models to create changes in decision making and actions; as a secondary socialization process where the vision of management is externalized as a business simulation that is in turn internalized by the organisation members that participate in the business simulation, or as a way to frame and define the reality of the organisational members which creates a shared reference point against which a feeling of organisation and direction can emerge. In the future, business simulations may become increasingly used by organizations to create a common vision or to communicate a new decision to the organization members..

Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when Computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.
