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 terrorist attack that shocked the world the 11th of September 2001, when two hijacked aircrafts flew into the World Trade Center's twin towers in New York, came to change the world view for many people especially Americans that felt that the world around them where about to collapse. A new time had begun, a more frighten one. A new kind of terrorism where seen in the dawn, a kind that never had been more evil, and there for was passed to be extremely dangerous. The United States followed by the United Kingdom decided quickly to declare war against the terrorism. Unavoidable this decision led to the development of new interpretations of public international law when the US where unwilling to follow the rule of law.

Vid större olyckor och kriser kan Försvarsmaktens helikoptrar nyttjas för bland annat sjukvårds-, transport-,släck-, flygräddnings- och sjöräddningsuppdrag. Sedan 2010 är Rakel det kommunikationssystem som används av de så kallade blåljusorganisationerna (Polis, Räddningstjänst, Ambulans, etc) samt vid krisledning i Sverige. I och med införandet av Rakel tappade Försvarsmaktens helikoptrar förmågan att kunna kommunicera och samverka effektivt vid olyckor och kriser med blåljusorganisationerna. Rakel är operativt i Försvarsmakten och Helikopterflottiljen men systemet finns inte att tillgå i helikoptrarna där behovet är störst.Målet med detta examensarbete var att ta fram ett tekniskt och taktiskt underlag för att undersöka om det är möjligt att installera Rakelsystemet i Försvarsmaktens helikoptrar och undersöka behovsbilden av Rakel vid insatser av civil karaktär..

The purpose of this thesis is to investigate the ways in which emotion regulation and mood affects risk taking when it comes to decision making competence. Emotion regulation is an essential part of the attachment process, the development of an autonomous self and functional stress coping systems. Research indicates that there is a relation between a distorted emotion regulation and some psychological disorders like depression, PTSD, anxiety disorders and borderline (or instable emotional personality disorder). There is a definite need to analyze the relation between emotion regulation and decision making competence since it is relatively unexplored. A digital questionnaire was distributed amongst the participants.

Tanzania is today one of the greatest aid recipients in the world, but still - after over 45 years of huge amounts of aid - one of the poorest and least developed countries. How can that be? Civil society is said to benefit the democratization process, but has not succeed in Tanzania. Has the extensive aid had any impact? Our purpose is to investigate this set of problems.We are using theories concerning civil society and aid in general, and the theoretical framework developed by Hadenius and Uggla ?Making Civil Society Work, Promoting Democratic Development: What Can States and Donors Do??, in particular.

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

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.

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

SammanfattningExamensarbetet har syftat till att undersöka möjligheten att utrusta Husqvarnas autonomagräsklippare med avståndssensorer. Dessa ska hindra gräsklipparen från att kollidera med hinder i sinomgivning. Gräsklipparen arbetar i en miljö där väder, temperatur, ljusförhållanden och underlagvarierar kraftigt. Detta innebär att kravet på sensorerna är högt.Av de sensorer som undersökts har det visat sig att ultraljud och ?structured light? är de system sombäst skulle kunna uppfylla all dessa krav till ett rimligt pris.I examensarbetet undersöks därför ultraljudssensorer från företaget Maxbotix närmare ochimplementeras i en prototyp.

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.

Obemannade markfarkoster är ännu ganska ovanliga i den svenska Försvarsmakten men borde kunna bli allt vanligare. UGV:er används traditionellt till att utföra smutsiga, tråkiga och farliga arbetsuppgifter. Kan de då vara användbara i Afghanistan mot den motståndare som FM möter där idag?I studien undersöker författaren möjligheterna för obemannade markfarkoster att bidra med militär nytta inom området logistiktransporter. De obemannade transportfordonen kan från grunden utgöras av standardlastbilar i FM som har utrustats med så kallade UGV-kit.

Detta examensarbete undersöker navigering för grupper av autonoma agenter i dataspelsmiljöer. Genom att kombinera olika styrbeteenden och beräkningsmodeller utvärderar arbetet vilken av dessa tekniker som är mest effektiv med avseende på tid och vägval i trånga spelmiljöer. En experimentmiljö har utvecklats som implementerar fyra stycken tekniker och utvärderar dessa i tre olika miljöer med 10 respektive 50 agenter som navigerar genom miljön. Som grund använder samtliga tekniker ett vägföljningsbeteende och ett flockbeteende. Det som skiljer teknikerna åt är vilken beräkningsmodell som används samt att två av teknikerna använder ett väggundvikelsebeteende.

Just how far is it possible to make learning of new parts for recognition and robot picking autonomous? This thesis initially gives the prerequisites for the steps in learning and calibration that are to be automated. Among these tasks are to select a suitable part model from numerous candidates with the help of a new part segmenter, as well as computing the spatial extent of this part, facilitating robotic collision handling. Other tasks are to analyze the part model in order to highlight correct and suitable edge segments for increasing pattern matching certainty, and to choose appropriate acceptance levels for pattern matching. Furthermore, tasks deal with simplifying camera calibration by analyzing the calibration pattern, as well as compensating for differences in perspective at great depth variations, by calculating the centre of perspective of the image.

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.
