At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

Communication of sustainable development has become an increasingly important part of organisation?s corporate branding. Consumers demand more transparency from businesses and want to know more about how they work with these issues. An important part of how internal communication can be used to reach organisational success involves organisation?s employees.

The purpose of our study is to determine whether a membership in FRII exercise any influence over the fundraising organizations accounting and work, and if that?s the case we want to study the effects.We began with a search for information about the theories we intended to use in our study and to establish hypotheses. We came to the conclusion that the agency theory and the stakeholder model were the most relevant theories for our work. We also chose to discuss problems in accounting, legitimacy theory and standard setting.We decided to conduct a total opinon poll due to the fact that FRII only have approximately seventy members. We also decided to conduct a cross section approach which means that the attempt of our study is broad but rather shallow.

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

The aim of this study is to evaluate whether the working model, presented by The Swedish Floorball Federation, has been a good method to work with gender equality within Swedish floorball associations. The purpose of the The Swedish Floorball Federation?sproject was for its associations to develop a plan of action for how to act to be an equal treatment association pursuing an equal treatment sport. 13 associations answered the questionnaire study. The result show that the great majority clearly found a need of change to become more equally treating and most of those associations have somewhat of an idea how to realize those changes.

In the 1960?s, Paul Hersey and Ken Blanchard developed a theory called Situational Leadership. Situational Leadership is a model where the leader analyses the needs of the situation and the needs of the people to be led. After analysing the situation, decision is made on what leadership style to adopt. The Situational Leadership model was developed in a company environment.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

The purpose of this essay is to state a fundamental model which can describe the sounds of the city, emphasizing on its rhythm. The essay is based on a theoretical study that deals with essential elements to describe a soundscape. The theories presented are founded on R. Murray Schafer's theses about soundscapes, Bert De Coensels theses about rhythmical sound patterns and Ambjörn Hugardts view on rhythm. The model that is presented stresses the importance of a multidisciplinary perspective when one attempts to understand and describe a soundscape.

This report is about Adobe Acrobat 3D and their new PDF format witch can contain 3 dimensional models that are interactive. The purpose is to find out if the program and the format work in a level that is suitable for the market. To create this PDF you need Acrobat 3D installed on your computer but it only needs Acrobat Reader 7 or 8 to open it, and the Reader is free to download on the internet.The examination is focusing on four formats: U3D, 3DS, DWG and DXF because they are the most common in the building industry seen from the architects? way. From a 3D model exported to these four formats they where converted to PDF in different settings to be compared in different points as information and size of the files.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

Aim: To find out what nurses at a hospital in central Sweden are experiencing as good care and what they believe is needed to achieve good care. To examine what barriers exist and how the work environment plays into good nursing care. Method: Descriptive and exploratory qualitative design with semi-structured interviews as the data collection method. Seven nurses, all women between the ages of 25 and 52 were interviewed at a hospital in central Sweden. An interview analysis model was used to analyze the results.

In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.

The aim of this study was to understand how three selected football associations in three counties in Sweden work to include children and adolescents with disability in the age of 7-20 in their organization.  For this study we have used a qualitative method. The data have been collected through using semi-structured interviews with coaches and representatives from the board. When analyzing the data, we used Charles Tilly's theory Durable Inequality and research within the area of inclusion within sports, the significance of activities and the inequality within sports. The conclusions of the study showed that there was a stated lack of knowledge in the associations when it comes to their work with young people with disabilities and also in their work with the policies.

This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.
