Classification of song similarities and differences in one bird species is a subtle problem where the actual answer is more or less unknown. In this paper, the singular vectors when decomposing the multitaper spectrogram are proposed to be used as feature vectors for classification. The advantage is especially for signals consisting of several components which have stochastic variations in the amp

Popular Abstract in English People normally associate hemoglobin with blood. It is true that the iron in the center of the hemoglobin molecule makes it excellent at carrying oxygen in the bloodstream from the lungs to every part of the body. However, seventy five years ago a hemoglobin was found in a plant. And plants do not have blood. So what is hemoglobin doing in plants? What are its functionsHemoglobins (Hb) are usually associated with blood in humans. However, these proteins are widely distributed among living organisms. In plants the most known group are the leghemoglobins. Still, other Hbs that not participate in symbiosis are also found. They are known as nonsymbiotic Hbs (nsHbs). NsHbs are divided into class-1 and class-2. In this thesis three nsHbs from sugar beet (BvHb1-1, BvHb

This essay examines the aesthetics and rhetoric through which popular science delivers the message of brain-mind conflation—‘You are your brain’. Noting the entwinement of realist and imaginary visual tropes in popular scientific presentations of brain imaging, author seeks a correlative ‘counter-text’ to this discourse in one of the classic texts in psychiatric history, the memoirs of the paranoi

Popular Abstract in Swedish Malaria parasiter skördar årligen runt 2 miljoner liv i regionerna söder om Sahara. De parasiter som orsakar malaria hos människor ingår i en stor grupp av blodparasiter som återfinns hos primater, reptiler, fladdermöss och fåglar. För att dessa parasiter ska kunna genomgå hela sin livscykel både ett ryggradsdjur och en blodsugande insekt (en vektor). I de blodsugande iMalaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. By using molecular methods to identify parasites from avian blood samples, I have found a diversity, based on the cytochrome b gene, that greatly exceeds the diversity prev

We studied the behavior of an iterative receiver using protograph based LDPC codes (PG-LDPCC) in an UWB short range communication system. An EXIT-Chart-Analysis is applied by means of density evolution of protographs. We show that AWGN-optimized protograph ensembles perform also well on frequency-flat UWB channels, outperform rate-compatible punctured convolutional codes (RCPC), but degrade with i

Från humlor, metanbomber och luftpartiklar till markkonflikter och klimatanpassning på medborgarnivå. Klimatförändringen och dess konsekvenser blir alltmer tydlig och sträcker sig allt längre in i samhällsfrågorna och vardagslivet. Klimatfrågan handlar dels om naturvetenskapliga frågeställningar, om atmosfärsprocesser och förändringar i havet och på tundran, och om naturresurser och tjänster som v

Popular Abstract in Swedish Denna avhandling syftar till att ge en översikt över cirka hundra år av europeisk intellektuell historia som lyfter fram nya aspekter av de klassiska tänkarna. Analysen av de fyra filosoferna Thomas Hobbes, John Locke, David Hume och Charles de Montesquieu syftar till att belysa en generell historisk process, nämligen hur den moderna människosynen växer fram i Europa. EThis essay has three main aims. The first one is to give an overview of some hundred years of European intellectual history, bringing out new aspects of the classical thinkers. The analysis of the four philosophers Thomas Hobbes, John Locke, David Hume and Charles de Montesquieu aims at illustrating a general historical process, viz. the emergence of the modern view of man in Europe. After Hobbes,

Six plutonium-containing particles stemming from Runit Island soil (Marshall Islands) were characterized by non-destructive analytical and microanalytical methods. Composition and elemental distribution in the particles were studied with synchrotron radiation based micro X-ray fluorescence spectrometry.
