This thesis visits the forefront of algorithmic research on edge coloring of cubic graphs. We select a set of algorithms that are among the asymptotically fastest known today. Each algorithm has exponential time complexity, owing to the NP-completeness of edge coloring, but their space complexities differ greatly. They are implemented in a popular high-level programming language to compare their p
Popular science summary Comparison of ectoparasite load on barnacle geese (Branta leucopsis) in arctic and temperate regions Some birds winter in warm regions, but breed in the arctic. This long migration takes up a lot of energy, which leaves scientists wonder why birds undertake this journey. One of the many hypotheses to explain it, is that there are fewer parasites in the arctic. Therefore,
This thesis presents methods for estimation and autonomous control of a hexacopter which is an unmanned aerial vehicle with six rotors. The hexacopter used is a ArduCopter 3DR Hexa B and the work follows a model-based approach using Matlab Simulink, running the model on a PandaBoard ES after automatic code generation. The main challenge will be to investigate how data from an Internal Measurement
Sammanfattning EU står inför en stor utmaning att kunna ta emot alla flyktingar som är på flykt. Idag är det främst de syriska flyktingar som är på EU:s agenda. Situationen i Syrien har tvingats miljontals människor på flykt och EU har ett stort ansvar att ta hand om de syriska flyktingar som kommer till dit. I EU pågår därför ett intensivt arbete att hitta lösningar på flyktingproblematiken, för Summary The Syrian refugees coming to Europe is a big challenge for the member states in the European Union. The situation in Syria has led to many millions of Syrians have fled their country of origin and they seek protection in nearby countries and in Europe. The European Union is facing a big problem in finding a solution for all these Syrians coming to Europe. During the last year, 2013, it ha
Abstract The present thesis is concerned with the investigation of a metalorganic catalyst, a Pt complex used for C-C or C-N single bond formation in a cross coupling reaction. The investigated catalysts are used in a homogeneous reaction. In this study I have used chemical methods for the synthesis of the catalytic materials, a number of different techniques for the characterization of the catal

The purpose of this thesis is to investigate how notions of public space take p
Under stora delar av det senaste århundradet har indelningen i ‘äkta’ och ‘oäkta’ underlåtenhetsbrott varit frekvent förkommande inom den svenska straffrättsvetenskapen. De moderna standardverken, inom straffrättens allmänna del, tenderar till och med att bygga upp sin presentation av underlåtenhetsansvaret kring en dylik indelning. Dessutom associeras det för underlåtenhetsansvar stundvis tillkomThe concepts of ‘authentic’ and ‘inauthentic’ crimes of omission have been frequently used by Swedish criminal law writers during the larger part of the last century. As of today, these concepts tend to be essential for the representation of criminal responsibility for omissions in the legal literature. Their importance cannot be understated, especially since the requirement of a ‘special duty to
This is a study of the implementation of the ALARP-principle in risk analyses performed as a part of land-use planning. Interviews conducted with active parties in the industry shows that the current guidelines for using the ALARP-principle results in a variation of the methods used to decide whether a risk can be considered reduced to ALARP. Furthermore several respondents are of the opinion that
Popular science summary As the climate warms and species move northwards, some species encounter populations of a similar species. In this case, the banded demoiselle damselfly Calopteryx splendens is moving north, further into Fennoscandia than it has been known to go before, and is meeting populations of the beautiful demoiselle damselfly Calopteryx virgo. Males of both species set up and defen

Bakgrund: I samband med palliativ vård är symtom såsom smärta, oro och ångest vanligt förekommande, men här framträder också existentiella behov. Dessutom kan existentiell, psykisk och andlig smärta vara mer smärtsam än den fysiska. Omvårdnadsforskning har visat att patienters existentiella behov ofta är försummade och att vårdpersonal undvikit att beröra frågor som gällde dessa behov. Syfte: StudBackground: In palliative care symptoms such as pain and anxiety are common, but also existential needs. Additionally, the existential, psychological and spiritual pain can be more painful than the physical. Nursing research has shown that patients` spiritual needs often are neglected and that health workers have avoided issues related to these needs. Objective: The aim of the study was to explore

The aim of our study was to investigate how the Swedish press and webbforums choose to portray cannabis and it’s use. The study was based on examining articles published in well established Swedish newspapers from august 2011 and on. The analysis was based on Håkan Jönsons perspective analysis, which have a strong connection to both social constructivism and discourse analysis. We aspired to exami
The aim and purpose of this paper was to examine the images of children and parenting, with a focus on parental separation and reconstruction of family and parenthood, which was constructed in internet forums. Which pictures emerge of separated mothers and fathers? My material was obtained from two large community pages for parents on internet. In my analysis I have chosen to be inspired by discou
Rape must be understood from a gender system and exposed women are often afraid of how they will be treated in the subsequent court procedure. The purpose of this essay is to examine how the Swedish courts construe women in rape trials and how this maintains and reinforces the gender system. To do this I am doing a critical discourse analysis of 20 reasoning of judgements with the theory of two fe
