As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

The United Nations has a responsibility to combat acts of international terrorism, as they constitute a threat to international peace and security. In spite of this, there exists no generally accepted definition of the phenomenom within the UN. By examining resolutions on terrorism, this thesis aims to evaluate the UN?s policy on terrorism since the end of the cold war until 2003. The results show that the UN?s attitude towards terrorism eversince the end of the cold war has been condemning, but that the the events of September 11th 2001 has contributed to an even more firm approach to the problem.

This thesis is a part of the DySCAS (Dynamically Self-Configuring Automotive System)project which has the overall purpose of creating a middleware for the electronics in an automotive environment. The thesis has been made with collaboration with ENEA AB who is a member of the DySCAS project. ENEA AB has developed a demonstration platform to test the fundamental ideas which the DySCAS project is built on.The purpose of this thesis was to design and implement a GPS application to be added to the demonstration platform. This was done by adding a GPS receiver to the original DySCAS demonstration platform and designing and implementing an application to be able to extract the information from it. The resulting application is able to present cur- rent position and absolute time to the DySCAS networks as services to be used by other applications or by the network it self.

The purpose of this study is to describe and analyze homelessness in a medium-sized municipality from an organizational perspective. Some of the central questions in this study are: How is the cause of homelessness explained? How do different actors in the community address, prevent and combat homelessness? Who is responsible for the homelessness?This study is based on four semi-structured interviews with organizations that work with homelessness. The analysis is based on problem definition theory.The result of this study shows that homelessness is a problem in this medium-sized municipality even if it is not a big one and that it is often closely combined with substance abuse. The responsibility for the homeless is on the homeless themselves and the social service because that causes is, according to this study, individual based.  .

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.

In the gaming industry, it has long been popular to combine genres with the aim ofcreating games that bring together the best of several worlds. However, there are stillmany unexplored combinations with good potential.This report addresses the planning and development of a game prototype that combinestwo game genres, turn-based and real-time strategy. In addition to presenting the results,the report also discusses the di culties that were encountered and how they were handled.The prototype contains a working combat system and a basic AI. The prototype ismodular, which means that it is easy for an end user to extend the game with extra content.Most elements that were considered important from the two genres were implemented, butthere is still room for improvement and further development.The result is evaluated by means of quality assurance, a process that is commonly usedin the gaming industry. The response has been generally positive, which indicates thatthe combination has potential and should be explored further..

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

This master thesis is a study of anaerobic thread lockers and is done in cooperation withÖhlins Racing AB, which is a Swedish manufacturer of vehicle suspensions.The suspension in vehicles is constantly exposed to high vibration levels and a suspensionunit has several screw- and cylindrical joints. As an extra safety precaution so that thecomponents in the suspension doesn?t fall apart when using the vehicle, an anaerobicthreadlocker is added in these joints. The handling of these threadlockers is not totallyharmless and could lead to allergic reactions, and therefore there are Swedish laws to limit theuse of these. However, new types of anaerobic threadlockers have recently been launched onthe marked that are not considered under this law.

In this paper I will present my research about different kinds of social workers, and there way of looking at and working with adolescents alcohol use. To get my result, we interviewed eight social workers from four different organizations. The Interview participants were people working with adolescents on their spare time, and in the school environment. There were also participants representing social services and the police. The theory that we have chosen to apply to our thesis is systems theory.

Denna uppsats syfte är att ta reda på om euron är en internationell valuta och omeuron kan konkurrera med dollarn om titeln som världens ledande valuta.

In this study our aim is to display a series of possible mechanisms which operateswithin the regions and societies were child soldiers were frequently andextensively used in combat tasks. Our study is based on the assumption thattoday's peace-building strategies are inadequate to describe certain problemsfaced by many post-conflict countries, especially in Africa. We argue that largeformations of child soldiers will, if not properly and immediately addressed, causeserve and structural problems in society, gravely hampering growth andinstitutional capacity. The Issues of Post Traumatic Stress and societal insecuritybrought on by the use of child soldiers poses a serious threat to society as a whole.In this study we use Uganda as an illustrative case to describe the mechanisms atwork..

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

This Masters Thesis considers tracking of ground targets. Since ground targets often are difficult to detect with sensors a track is easily lost in ground target tracking. The main question in this thesis is whether information on close targets and observations of them can be used to make the tracking more reliable. An algorithm using Kalman filters and JPDA-association to create a group track for vehicles travelling together has been implemented in Matlab. Using the state of the centre of the group the state of a vehicle in the group can be updated.
