4. 2. Probabilistic Modelling of Hearing : Speech Recognition and Optimal Audiometry

   Author : Svante Stadler; Arne Leijon; Stefan Stenfelt; KTH; []
   Keywords : auditory models; probabilistic modelling; speech modelling; human speech recognition; hearing aids; cochlear implants; psychoacoustics; diagnostic methods; optimal experiments; audiometry;

   Abstract : Hearing loss afflicts as many as 10\% of our population.Fortunately, technologies designed to alleviate the effects ofhearing loss are improving rapidly, including cochlear implantsand the increasing computing power of digital hearing aids. Thisthesis focuses on theoretically sound methods for improvinghearing aid technology. READ MORE

5. 3. Modelling Sexual Interactions : Sexual behaviour and the spread of sexually transmitted infections on dynamic networks

   Author : Disa Hansson; Tom Britton; Fredrik Liljeros; KaYin Leung; Janneke Heijne; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; Sexually transmitted infections; Egocentric network analysis; Dynamic networks; Sexual behaviour; HIV; Statistical inference; Mathematical Statistics; matematisk statistik;

   Abstract : In this thesis we develop statistical and mathematical models to study different factors of relevance for the spread of sexually transmitted infections (STIs). Two special interest groups for STI interventions are considered: sexually active youths and men who have sex with men (MSM). READ MORE

6. 4. Population ecology and management of waders breeding on coastal meadows

   Author : Richard Ottvall; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; Djurekologi; grazing management; population modelling; demography; genetic structure; population decline; Tringa totanus;

   Abstract : Many wader (Charadrii) populations are declining throughout in Europe, but the underlying causes are often poorly known and diverse. To fully grasp the reasons behind declines in vulnerable wader populations, it is crucial to understand the demography. READ MORE

7. 5. Home, Job and Space : Mapping and Modeling the Labor Market

   Author : John Östh; Bo Malmberg; Lena Magnusson; Stewart Fotheringham; Uppsala universitet; []
   Keywords : Social and economic geography; GIS; ELMO; Estimated Labor Market Outcome; Estimated Labour Market Outcome; Accessibility; Access; Job Accessibility; Place; Employment; Unemployment; Labour; Labor; Labor Market; Labour Market; Topology; Local Labour Market Area; Modelling; Modeling; Spatial Modelling; Spatial Modeling; Spatial Mismatch; SMH; Mismatch; Commuting; Regionalization; Geography; Population Geography; Economic Geography; Time-geography; Space; Kulturgeografi;

   Abstract : How does space affect individuals’ outcome on the labor market? And how do we measure it? Beyond the notion of the labor market as a system of supply and demand, lays a society of individuals and workplaces, whose relationships are undeniably complex. This thesis aims to shed some new light on how to investigate and analyze the complex labor market relationships from a spatial perspective. READ MORE
