A new method for characterization of simultaneous intra-atrial and ECG recordings during atrial fibrillation (AF) is presented. With different preprocessing, both types of signals are characterized using a logarithmic time-frequency distribution from which trends of frequency, regularity, morphology (only ECG) and signal quality are extracted. The objective of the study is to relate ECG measures o

Voltage collapse was one of the main causes for many recent blackouts. The direct link between voltage stability and reactive power balance in the system leads to more attention toward reactive power resources in the power systems. Shunt reactors and capacitors are used to balance reactive power in the power systems. The strategy to control them in both normal and emergency conditions is an import

Thread-Level Speculation can be used to take advantage of multicore architectures for web applications. We have implemented Thread-Level Speculation in the state-of-the-art JavaScript engine V8 instead of using an interpreted JavaScript engine. We evaluate the implementation with the Chromium web browser on 15 popular web applications for 2, 4, and 8 cores. The results show that it is beneficial t

Popular Abstract in Swedish När ett barn föds före graviditetsvecka 30 är andningsinsufficiens eller på engelska kallad respiratory distress syndrome (RDS) ett av de stora kliniska problemen som barnläkaren står inför. Redan på 1920-talet förstod man att det måste finnas ett ytspänningsnedsättande ämne i lungorna och på 1950-talet fann man att för tidigt födda (prematura) barn med RDS hade brist pUsing an animal model, the thesis explores how the initial ventilation of the lungs, and surfactant therapy, should best be managed after premature birth. Material and measurements: The studies were made in newborn lambs delivered by cesarean section. Spread of exogenous surfactant was analysed by mixing it with technetium-labelled macroaggregated human serum albumin and imaging the radioactivity

Detta är den tredje och avslutande delen i trilogin "Slaveri - en världshistoria om ofrihet". I centrum för volymen står kampen mot slaveri, en kamp som inleddes i slutet av 1700-talet och kulminerade hundra år senare - men som ännu inte är avslutad. Efter ett inledande kapitel om de första abolitionisterna följer en beskrivning av utvecklingen i Västindien, Latinamerika och USA. I USA växte värld

In recent years, we have seen the development of a more relational approach to territoriality. This perspective, which focuses on events rather than space, also opens up for an elaboration of temporal aspects of territorial production. In this study, I investigate the central urban square, Stortorget, in Malmö, Sweden, in order to develop a discussion of urban time-space territorology. In 1978, Ko

Popular Abstract in Swedish Spridning och inavel i naturen I modern tid har vi människor orsakat stora förändringar i miljön, vilket påverkat många arters livsbetingelser. Exempelvis har vi avskogat stora områden och efterlämnat små delar av de större områden som tidigare hängde ihop. Organismer som lever i sådana uppsplittrade miljöer kommer att vara isolerade från varandra, vilket får som följdTo evaluate how inbreeding affects the viability of small populations, it is crucial to determine what constitutes a population (i.e., the number of breeders in local patches and the degree of dispersal), and also to estimate the reproductive consequences of philopatry and emigration. In this thesis, I concentrate on dispersal, inbreeding and fitness in natural populations. I consider dispersal ra
