2. 1. Bounded Horizons : A study of upper secondary school choice for newly arrived students

   Author : Brendan Munhall; Fredrik Hertzberg; Larissa Mickwitz; Daniel Lövheim; Ee-Seul Yoon; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; newly arrived students; school choice; horizon for action; boundaries; upper secondary school; educational policy; educational marketization; pedagogik; Education;

   Abstract : Graduating primary school students in Sweden choose their upper secondary school within a unique quasi-market school system. The students may choose specialized programs but must also be accepted based on grade rankings by the schools. Despite equity arguments for the school choice model, opportunities are not equally available for all students. READ MORE

4. 2. Towards Asymptotic Vector Quantization

   Author : Jonas Samuelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EM algorithm; parametric models; expectation maximization; spectrum coding; Gaussian mixture models; fast search; bounded support; multidimensional companding; vector quantization; high rate quantization;

   Abstract : We study topics in source coding, and vector quantization (VQ) in particular. We approach VQ from two directions: a theoretical starting point based on high rate quantization theory, and a practical based on a database desription of the signal source. READ MORE

5. 3. Coding Speech for Packet Networks

   Author : Jonas Lindblom; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packet loss concealment; voice over IP; speech coding; harmonic modeling; vector quantization; sinusoidal modeling; Gaussian mixture modeling; bounded support; frame erasure; variable dimension;

   Abstract : The topic of this thesis is speech coding for packet networks. Problems related to the use of packet networks for voice communication are addressed. Real-time voice communication is for example very delay sensitive; if the total end-to-end delay in a telephone session grows large, it is perceived as annoying. READ MORE

   Author : Jonas Lindblom; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; bounded support; voice over packet packetized speech; spectrum prediction; Gaussian mixture modeling; frame erasure; speech coding; packet loss concealment; sinusoidal modeling;

7. 5. Pharmacometric Investigations of Prediction Precision and Advances of Models for Composite Scale Data

   Author : Gustaf Wellhagen; Maria C. Kjellsson; Bengt Hamrén; Per Olsson Gisleskog; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; modelling; non-linear mixed effects modelling; composite scale data; total score data; total score analysis; precision prediction; bounded integer; bounded integer model; IRT-informed total score analysis; item response theory-informed; mixed models for repeated measures; MMRM; dose-response; dose-response mixed models for repeated measures; DR-MMRM; HbA1c models; fit-for-purpose analysis; clinical trial analysis; Farmaceutisk vetenskap; Pharmaceutical Science;

   Abstract : Clinical trials are needed to evaluate new treatments. In late-stage clinical trials, failures are mostly due to lack of efficacy. Fit-for-purpose analysis methods will likely increase the success rates and advance drug development by providing higher precision to support decisions such as go/no-go, dose selection, or sample size.
