   Sammanfattning : This thesis deals with the development of the DP (the Determiner Phrase) in bilingual first (2L1) and in adult second (L2) language acquisition of Italian, with a focus on a case study of Italian as a second first language. The thesis suggests that the bilingual children and the Swedish adult learners develop the Italian DP differently. LÄS MER

3. 2. Automatic Instance-based Tailoring of Parameter Settings for Metaheuristics

   Författare :Felix Dobslaw; Theo Kanter; Åke Malmberg; Thomas Bartz-Beielstein; Mittuniversitetet; []
   Nyckelord :Algorithm Configuration; Parameter Tuning; Parameter Control; Metaheuristics;

   Sammanfattning : Many industrial problems in various fields, such as logistics, process management, orproduct design, can be formalized and expressed as optimization problems in order tomake them solvable by optimization algorithms. However, solvers that guarantee thefinding of optimal solutions (complete) can in practice be unacceptably slow. LÄS MER

4. 3. Optimal portfolios in the high-dimensional setting : Estimation and assessment of uncertainty

   Författare :Erik Thorsén; Taras Bodnar; Joanna Tyrcha; Mark Podolski; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shrinkage estimator; high-dimensional covariance matrix; random matrix theory; optimal portfolios; parameter uncertainty; ridge regularization; dynamic decision making; matematisk statistik; Mathematical Statistics;

   Sammanfattning : Financial portfolios and diversification go hand in hand. Diversification is one of, if not, the best risk mitigation strategy there is. If an investment performs poorly, then it will not impact the performance of the portfolio much due to diversification. Modern Portfolio Theory (MPT) is a framework for constructing diversified portfolios. LÄS MER

5. 4. Subspace-Based Parameter Estimation Problems in Signal Processing

   Författare :Joakim Sorelius; Torsten Söderström; Peter Stoica; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor array processing; parameter estimation; spread spectrum communication; direct sequence CDMA; order estimation; subspace fitting; blind identification; system identification; Signal Processing; Signalbehandling;

   Sammanfattning : The effects of multipath-induced angular spread and non-zero band-width on narrow-band direction-of-arrival (DOA) estimation are investigated. In both cases expressions for the resulting estimation error are developed for the MUSIC, ESPRIT and WSF DOA estimators. LÄS MER

7. 5. Parameter and State Estimation with Information-rich Signals

   Författare :Magnus Evestedt; Alexander Medvedev; Fredrik Gustafsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; information-rich signals; audio; video; acoustic echo cancellation; steel production; LD-converter; Kalman filter; covariance windup; recursive parameter estimation; Automatic control; Reglerteknik;

   Sammanfattning : The complexity of industrial systems and the mathematical models to describe them increases. In many cases, point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. LÄS MER
