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

   Författare :Linda Olsson; Ulf Träff; Joakim Samuelsson; Lisa Thorell; Linköpings universitet; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 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

3. 2. Continuous time Graphical Models and Decomposition Sampling

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

4. 3. Computational Modelling of Early Olfactory Processing

   Författare :Malin Sandström; Anders Lansner; Jeanette Hällgren Kotaleski; Thomas Nowotny; KTH; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

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

   Författare :Naveed Butt; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

7. 5. Climate Change, Dengue and Aedes Mosquitoes : Past Trends and Future Scenarios

   Författare :Jing Liu-Helmersson; Joacim Rocklöv; Åke Brännström; Eduardo Massad; Richard Paul; Umeå universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dengue; mathematical modelling; vectorial capacity; DTR; Aedes aegypti; Aedes albopictus; climate change; Europe; vector invasion; abundance; dengue; matematisk modellering; vektorkapacitet; DTR; Aedes aegypti; Aedes albopictus; klimatförändring; Europa; vektor invasion; epidemiologi; Epidemiology;

   Sammanfattning : Background Climate change, global travel and trade have facilitated the spread of Aedes mosquitoes and have consequently enabled the diseases they transmit (dengue fever, Chikungunya, Zika and yellow fever) to emerge and re-emerge in uninfected areas. Large dengue outbreaks occurred in Athens in 1927 and in Portuguese island, Madeira in 2012, but there are almost no recent reports of Aedes aegypti, the principal vector, in Europe. LÄS MER
