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.

Information technology (IT) have for several decades been used in university education. An increasing number of classrooms today are built around a concept which uses IT in collaboration with the room itself. However, little is known about the experience of university teachers when working in such classrooms. This study examines the views and opinions of teachers at a Swedish university regarding using and interacting with these classrooms. Furthermore, we identify possible underlying factors that influence these views.

Placed within the field of recent research concerning religion and contemporary religious landscapes, this thesis aims to show conceptions of human life and body displayed in ten Swedish health magazines. The analysis aims to demonstrate the appearance of body and bodily experience and in addition see in what way ?westernized? religious traditions and methods from east Asia may contribute to perspectives of health. The main theories for the study are objectified versus phenomenological understanding of the human body by Drew Leder (1992; 1990) and Kristen Zeiler (2010). The quote in the main title is from the empirical material (Hälsa & Fitness, 2014 (11), cover).

The issue of sick leave and an increase of ill health in the workplace is a social problem inSwedenthat is currently an important topic. Public human service organisations are one of the sectors where this is a major problem. The aim of this study is to examine what significance the leadership in public human service organisations has on the health and sense of well being among the staff within the organisation. We have chosen to look at this issue from a health promoting perspective where we focused on health factors and to what extent the management can influence and promote the possibilities for a healthy workplace with healthy staff. The results of the study are based on interviews with three leaders within the public human service sector.

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.

The purpose of this study was to examine whether there was any connection between coping strategies; emotional and cognitive strategy and perceived level of stress among primary school teachers in primary and middle school. It was also investigated whether there was a difference between full-time and part-time employees and perceived level of stress. As a theoretical background Lazarus' transaction theory of stress was used as an explanation of mental stress, Lazarus coping strategies for stress and Karasek?s and Theorell?s model of psychosocial work environment was used to explain unhealthy at work. To measure coping we used Coping inventory resources and to measure the stress we used Percieved stress scale.

The European Union is struggling to maintain democracy and tries to increase the participation among the citizens in Europe. The European Citizens? Initiative, ECI, is a platform established by the European Commission to allow citizens to propose new legislation. ?Water and sanitation are a human right! Water is a public good, not a commodity!? is the first ECI that has met the requirements.

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.

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.

Real estate agent is a popular occupation that many young people study today. They enter the market and will have to compete with experienced real estat agents. Why should the customer choose them instead of those with more experience? We describe the character of services offered, expectations and customer satisfaction. We have chosen to give a questionnaire to customers and real estat agents.

The thesis examines the nineteenth century German philosopher and philologist Friedrich Nietzsche?s early notion of how a word is generated in the process of perception. It does so by looking at the ?metaphorical transitions? Nietzsche talks about in the essay ?Über Wahrheit und Lu?ge im außermoralischen Sinne? (?On Truth and Lie in an Extra-MoralSense?). According to the relevant passage in ?On Truth and Lie?? an image is first created as a metaphor for a stimulus and a word is then created as a metaphor for the image.

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.

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

Background: Enterprises often refer to their employees as ?Our most valuable assets? in annual reports and other written statements. In reality, employees are seen as an expense rather than an asset in annual reports and the voluntary disclosure is often insufficient. Human capital disclosure has been discussed through decades and the latest topic in voluntary disclosure is called integrated reporting. Knowledge firms should disclose more about their employees than industrial companies due to the fact that the employees are a considerably more important asset to these types of enterprises.Purpose: The purpose of this thesis is to study the disclosure of human capital, compare the disclosures between knowledge firms and industrial companies, and study the development of the human capital disclosures between the years 2003-2013.
