1. 16. Knowledge-based speech enhancement

   Författare :Sriram Srinivasan; Bastiaan Kleijn; Rainer Martin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech enhancement; noise reduction; linear predictive coe±cients; autoregressive; codebooks; maximum-likelihood; Bayesian; nonstationary noise; blind source separation.; Telecommunication; Telekommunikation;

   Sammanfattning : Speech is a fundamental means of human communication. In the last several decades, much effort has been devoted to the efficient transmission and storage of speech signals. With advances in technology making mobile communication ubiquitous, communications anywhere has become a reality. LÄS MER

3. 17. 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. 18. Development of new methods for miniaturized separation techniques

   Författare :Marcus Öhman; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

   Sammanfattning : The aim of this study has been to develop and investigate separation methods for miniaturized systems. Micro liquid chromatography was coupled on-line with a mass spectrometer equipped with an electrospray ionization source for the separation and characterization of flavonoids in Citrus juices.

5. 19. Study of MFI zeolite membrane for CO2 separation

   Författare :Shahpar Fouladvand; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : Nowadays, the need and interest for renewable sources of energy has increased. Biogas is a renewable source of energy that can be considered as a sustainable substitute for natural gas. LÄS MER

7. 20. Elucidating the Influence of Food Packaging Attributes on Source-separation of Food Packaging Waste at Home

   Författare :Babak Nemat; Kamran Rousta; Isabel Ordonez; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Household waste; packaging attributes; packaging waste; consumer s recycling behavior; Resource Recovery; Resursåtervinning;

   Sammanfattning : The global amount of waste generated by households, including food packaging waste, has been increasing continuously across the world, posing a massive threat to societies and the environment. Proper waste management, therefore, has become a challenging environmental issue and a priority for governments. LÄS MER
