  1. 1. Bifurcations and Exchange of Stability with Density Dependence in a Coinfection Model and an Age-structured Population Model

    Författare :Jonathan Andersson; Vladimir Kozlov; Uno Wennergren; Ezio Venturino; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In nature many pathogens and in particular strains of pathogens with negative effects on species coexists. This is for simplicity often ignored in many epidemiological models. It is however still of interest to get a deeper understanding how this coexistence affects the dynamics of the disease. LÄS MER

  3. 2. “Count on me!” : Mathematical development, developmental dyscalculia and computer-based intervention

    Författare :Linda Olsson; Ulf Träff; Joakim Samuelsson; Lisa Thorell; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematical development; symbolic number processing; Approximate number system; developmental dyscalculia; computer-based intervention; matematisk utveckling; symboliskt nummerprocessande; Approximativa nummersystemet; dyskalkyli; datorbaserad intervention;

    Sammanfattning : A “sense” of number can be found across species, yet only humans supplement it with exact and symbolic number, such as number words and digits. However, what abilities leads to successful or unsuccessful arithmetic proficiency is still debated. LÄS MER

  4. 3. Continuous time Graphical Models and Decomposition Sampling

    Författare :Jonas Hallgren; Timo Koski; Blazej Miasojedow; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Two topics in temporal graphical probabilistic models are studied. The topics are treated in separate papers, both with applications in finance. The first paper study inference in dynamic Bayesian networks using Monte Carlo methods. A new method for sampling random variables is proposed. LÄS MER

  5. 4. Computational Modelling of Early Olfactory Processing

    Författare :Malin Sandström; Anders Lansner; Jeanette Hällgren Kotaleski; Thomas Nowotny; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfaction; olfactory system; olfactory bulb; olfactory receptor neuron; synchronization; CaMKII; mathematical modelling; lukt; luktsystemet; luktbulben; synkronisering; CaMKII; matematisk modellering; Computer science; Datavetenskap;

    Sammanfattning : Chemical sensing is believed to be the oldest sensory ability. The chemical senses, olfaction and gustation, developed to detect and analyze information in the form of air- or waterborne chemicals, to find food and mates, and to avoid danger. LÄS MER

  7. 5. ROBUST DETECTION AND SPECTRAL ANALYSIS OF SIGNALS WITH APPLICATIONS IN SPECTROSCOPY

    Författare :Naveed Butt; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Detection; NQR; NMR; Raman Spectroscopy; Spectral Analysis.;

    Sammanfattning : Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic techniques. LÄS MER
