1. 11. System Modeling Using Basis Functions and Application to Echo Cancelation

   Författare :Lester S.H. Ngia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laguerre filters; Gauss-Newton algorithms; Levenberg-Marquard algorithms; room acoustics; separable nonlinear least-squares; adaptive filtering; off-line estimation; echo cancelation; on-line estimation; system modeling; neural net filters; Kautz filters; loudspeaker systems; steepest-descent algorithms; Hammerstein models;

   Sammanfattning : This thesis concerns modeling of linear and nonlinear dynamic systems, where the applied models can be described by basis function expansions. In the first part of the thesis, the investigated model (or filter) structures and parameter estimation algorithms are described. LÄS MER

3. 12. Bayesian Modeling of Directional Data with Acoustic and Other Applications

   Författare :Jalil Taghia; Arne Leijon; W. Bastiaan Kleijn; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directional statistics; directional distributions; axial distributions; von Mises-Fisher distribution; complex Watson distribution; complex Bingham distribution; Bayesian inference; probabilistic modeling; variational inference; two-dimensional hidden Markov models; Markov chain; blind source separation; frequency domain BSS; underdetermined BSS; online BSS; Bayesian recursive; gene expression data; gene-microarray data; line spectral frequency; speaker identification. ii;

   Sammanfattning : A direction is defined here as a multi-dimensional unit vector. Such unitvectors form directional data. Closely related to directional data are axialdata for which each direction is equivalent to the opposite direction.Directional data and axial data arise in various fields of science. LÄS MER

4. 13. Murine plasmacytomagenesis : an experimental model of B-cell neoplasia

   Författare :Santiago C Silva; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :mouse plasmacytomas; chromosomal translocation; chimeric mice; MYC-transgenic mice; ;

   Sammanfattning : A chromosomal translocation which results in the illegitimate activation of the c-myc proto-oncogene by one of the three immunoglobulin (Ig) loci is invariably associated with human Burkitt's Lymphoma (BL), mouse plasmacytoma (MPC) and rat immunocytomas (RIC). In the MPC system a genetic predisposition linked to the BALB/c strain has been suggested. LÄS MER

5. 14. Travelling Business Models : On adapting business models to new contexts

   Författare :Kajsa Ahlgren Ode; Innovationsteknik; []
   Nyckelord :affärsmodell; innovation; översättning; hållbarhet; process; solenergi; business model; innovation; translation; sustainability; process; solar energy;

   Sammanfattning : How business models are configured can provide one solution to bringing forward sustainable innovations and transforming businesses and industries so that they become more sustainable. Creating a shift in the energy sector’s use of renewable sources is of particular importance since the energy sector is the source of one-fourth of all global greenhouse gas emissions. LÄS MER

7. 15. On the Realization of Credible Simulations in Aircraft Development : Efficient and Independent Validation Enabled by Automation

   Författare :Robert Hällqvist; Petter Krus; Magnus Eek; Robert Braun; Gerhard Schmitz; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft Vehicle Systems; Credibility Assessment; FMI; Interoperability; Modelica; Modeling and Simulation; Model integration; SSP;

   Sammanfattning : Designing modern aircraft is not an easy task. Today, it is not enough to optimize aircraft subsystems at a subsystem level. Instead, a holistic approach is necessary whereby the constituent subsystems need to be designed for the best joint performance. LÄS MER
