Popular Abstract in English Insects, birds, bats and pterosaurs have all evolved the ability to fly, even though it requires a lot of energy. The advantage is obvious: one can move about vertically, to go where others cannot, find and access distant food sources or escape your predators. But flying is also a very fast mode of transportation, and when you count the amount of energy required to get Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. To this end I studied the aerodynamic performance of a jackdaw (Corvus mone

This study concerns fundamental analysis and predictive modelling of heat and mass transfer in frozen hamburger patties cooked in a double-sided contact fryer. Mathematical and physical models are formulated and further developed to enable improved understanding of the transport processes and reveal the influence of essential parameters. Prediction and analysis of practical situations with heating

X-ray diffraction methods have been used to study the crystal structure of different compounds, both organic and inorganic. The inorganic compounds were all synthesized by solid state reactions. A new compound, Re4As6S3, was synthesized and its structure was solved by Rietveld methods. Re4As6S3 is a cluster compound described by a rock-salt-type arrangement of ReAsS3- and As5- clusters. This stru

Esports is computer games played in a competitive environment, and analytics in this domain is focused on player and team behavior. Multiplayer Online Battle Arena (MOBA) games are among the most played digital games in the world. In these es, teams of players fight against each other in enclosed arena environs, with a complex gameplay focused on tactical combat. Here we present a technique for se

2015 markerar 100-årsminnet av armeniska folkmordet i Osmanska imperiet under första världskriget. Denna publikation är ett led i programmet för ihågkommandet av folkmordets 100-årsminne och innehåller de hundra mest förekommande frågorna. Boken innehåller korta sammanfattade svar till dessa frågor med källhänvisningar och referenser till andra litteratur som läsaren kan sedan använda för vidare f

This doctoral thesis examines labour market legislation concerning disability and work in Sweden, England and Germany. In order to provide increased access to the labour market for people with disabilities, all these countries have undertaken more of less far-reaching legislative measures over a number of decades, both in line with, or as a result of, general labour and employment legislation, but

Stuttering is one of the most common speech disorders. However, the etiology is poorly understood, and is likely to be heterogeneous. The aim of this thesis was to clarify causal mechanisms, focusing the brain. The project included theoretical development based on published data, and a broad approach of explorative studies and testing of hypotheses. The theoretical work focused the basal ganglia,
