Popular Abstract in English Animal flight has always intrigued people, and different aspects of animal flight have therefore widely been studied by biologists, physicists and engineers. At least to me, the aspect concerning the aerodynamics of animal flight in particular is very interesting because of the complex temporal varying wake dynamics as a result of continually wing morphing in flapping fThe efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. Using these methods, I have studied flight of the Pied Flycatcher (Ficedula hypoleuca), the Pallas’ Long

Neutral photodissociation processes and non Franck-Condon effects in the N2 and O2 molecules induced by excitation with synchrotron radiation photons have been studied in the 15-35 eV region. Neutral dissociation processes have been studied by monitoring dispersed fluorescence from excited N and O atoms. The excited atoms are created through excitations to members of the molecular Rydberg seri

The philosophical debate about liberty has recently gained in complexity and political relevance through the revival of the republican understanding of liberty as the absence of asymmetric power relations or domination. As a staunch defender of the importance of theorizing liberty in this way, I nevertheless argue that a theory of liberty in the social world needs to be conceptually multifaceted a

The book is a history of the medieval city of Söderköping in the Swedish province of Östergötland, which was founded in the beginning of the thirteenth century. It is based on the numerous archaeological finds that have been unearthed in the city, as well as on the documentary sources in various archives.

A low-rate turbo coding scheme based on superorthogonal convolutional encoders is examined. We analyze the asymptotic performance that can be achieved when both the code length and the number of iterations tend to infinity and present a bound on the iterative limit of this superorthogonal turbo code construction. Simulations of the codes with large permutors (interleavers) confirm the results of t

Popular Abstract in Swedish Kärnmagnetisk resonans (NMR) är en metod som bygger på att många atomkärnor uppför sig som mycket små magneter. Detta i sin tur beror på att kärnan beter sig som en liten roterande laddning. Man säger att kärnan har ett spinn, eller att kärnan är ett spinn. I min avhandling använder jag mig av en fantastisk egenskap hos kärnspinnen. Om man stör systemet kommer det att In the work presented, nuclear magnetic resonance (NMR) relaxation is used to study wide range of systems. The thesis concerns solvent interactions studied with relaxation techniques that involve measurements at many fields, which allows the separation of individual relaxation mechanisms. The approach also makes it possible to characterize the involved dynamic properties in much greater detail. T

Popular Abstract in Swedish Sammanfattning Mänskliga aktiviteter och klimatförändringar påverkar vegetationen över hela jorden, idag och i framtiden. Denna påverkan kan studeras och kvantifieras med hjälp av observationer från satelliter vilka förmedlar information om vegetationsförändringar i tid och rum. I denna doktorsavhandling har metoder för analys av vegetationsförändringar utvecklats och Abstract This thesis aims to advance the analysis of nonlinear trends in time series of vegetation data from Earth observation satellite sensors. This is accomplished by developing fast, efficient methods suitable for large volumes of data. A set of methods, tools, and a framework are developed and verified using data from regions containing vegetation change hotspots. First, a polynomial-fittin

Konst på internet för en undangömd tillvaro så länge som vi inte riktar blicken mot de mest framgångsrika objekten som lever i detta nya medium, nämligen spelen. Artikeln placerar in spel och visuella objekt i spel inom ramen för samtida offentlig konst.

Popular Abstract in Swedish Ändamålet med studien var att identifiera prognostiska och etiologiska riskfaktorer för melanom och dess relation till histopatologi. Studie 1-3 innefattade 711 patienter från 1965-1989. Vi fann en mediantjocklek som varierade mellan 1,1 och 1,4 mm, utan något statistiskt förändring genom åren och en ökning av andelen tunna tumörer (The purpose was to study the prognostic and aetiologic risk factors for melanoma in correlation to histopathology. Paper 1-3: Thin tumours (
