Laser-induced incandescence (LII) is a versatile technique for quantitative soot measurements in flames and exhausts. When used for particle sizing, the time-resolved signals are analysed as these will show a decay rate dependent on the soot particle size. Such an analysis has traditionally been based on the assumption of isolated primary particles. However, soot particles in flames and exhausts a
The main topic of this thesis is the investigation of small molecules adsorbed on metal surfaces by means of core-level photoemission spectroscopy. The thesis consists of three parts; The first group of papers concerns the effects of internal molecular vibrations on the core-level photoemission spectra. The second and third groups of papers concern more basic adsorption properties, like adsorption
A critical and evaluative study of the eight Commissions of the Edinburgh 1910 World Missionary Conference, including papers commissioned from leading Third World theologians, with substantive Introduction and Conclusion by editors. The book represents a major contribution to the preparation of the 2010 international centenary conference, also to be held in Edinburgh.
This paper presents dataflow machines, a model for stream programs aimed at capturing their logical structure in a way that is amenable to analysis, composition, and hardware and software code generation. We discuss the properties of the model, and its relationship to a previous effort, actor machines. Dataflow machines are motivated by the shortcomings of actor machines when generating highly par
Fundamental bounds on single-port antennas and on array antennas have been shown to depend on the electric and magnetic polarizability tensors. We show four such cases and compare how the polarizabilities enter into the bounds. One of the critical items in using these bounds is the determination of the polarizabilities. We here review methods to obtain the polarizabilities, and discuss some of the

During the whole evacuation modelling process, there are uncertainties in every task. To date, scarce literature is available on the assessment of those uncertainties and evacuation model users generally do not present this information consistently (if omitted at all) in evacuation modelling studies. Considering the classification made in other modelling fields (e.g. fire modelling), uncertainties
Popular Abstract in Swedish Nedfall av radioaktiva ämnen, framförallt Cs-137 från atmosfäriska kärnvapenprov och från Tjernobylolyckan, ger idag ett bidrag till den bakgrundsstrålning vi utsätts för. På grund av att Cs-137 har en förhållandevis lång halveringstid (30 år) kommer detta radioaktiva ämne att finnas kvar i ekosystemen för lång tid framöver och det är därför betydelsefullt att studera dIn this thesis a variety of sampling methods have been utilised to assess the amount of deposited activity, mainly of Cs-137, from the Chernobyl accident and from the nuclear weapons tests. Starting with the Chernobyl accident in 1986 sampling of air and rain was used to determine the composition and amount of radioactive debris from this accident, brought to southern Sweden by the weather systems
Popular Abstract in Swedish Den elektriska aktiviteten i hjärtats förmak vid kroniskt förmaksflimmer Bakgrund: Det mänskliga hjärtmuskeln består av fyra delar som var och en omsluter ett hålrum, vänster och höger förmak samt vänster och höger kammare. Ett hjärtslag, dvs den sammandragning av hjärtmuskeln som pumpar runt blodet i kroppen, utlöses normalt av att en elektrisk impuls bildas i sinuskChronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. However, there is a lack of
