  1. 1. Issues of incompleteness, outliers and asymptotics in high dimensional data

    Author : Peter S. Karlsson; Thomas Holgersson; Ghazi Shukur; Åke E. Andersson; Jönköping University; []

    Abstract : This thesis consists of four individual essays and an introduction chapter. The essays are in the field of multivariate statistical analysis of High dimensional data. The first essay presents the issue of estimating the inverse covariance matrix alone and when it is used within the Mahalanobis distance in High-dimensional data. READ MORE

  2. 2. The acquisition of contrast : a longitudinal investigation of initial s+plosive cluster development in Swedish children

    Author : Fredrik Karlsson; Kirk P. H. Sullivan; Peter E. Czigler; Marilyn M. Vihman; Umeå universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; phonological contrast; speech development; place and manner of articulation; aspiration; structural complexity; acoustic cues; homonym production; Phonetics; Fonetik;

    Abstract : This Thesis explores the development of word-initial s+plosive consonant clusters in the speech of Swedish children between the ages of 1;6 and 4;6. Development in the word-initial consonant clusters is viewed as being determined by 1) the children’s ability to articulate the target sequence of consonants, 2) the level of understanding of which acoustic features in the adult model production are significant for the signalling of the intended distinction, and 3) the children’s ability to apply established production patterns only to productions where the acquired feature agrees with the adult target, to achieve a contrast between rival output forms.

  3. 3. Radio Resource Sharing in Hierarchical Cellular Systems

    Author : Robert S. Karlsson; KTH; []
    Keywords : ;

    Abstract : Hierarchical Cell Structures (HCSs) is generally believed tobe a solution to capacity problems of future mobilecommunication systems. In such systems we have a mix of cellsizes that handle different types of traffic. We can have largecells providing wide area coverage and small cells providinghigh capacity. READ MORE

    Author : Mattias E. Karlsson; Richard Olsson; Mikael Skrifvars; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; nanocomposites; HVDC; conductivity; metal oxide; nanoparticles; surface functionality; polyeten; nanokompositer; HVDC; konduktivitet; metalloxider; nanopartiklar; ytfunktionalitet; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Power transmission over long distances by using high voltage direct current (HVDC) cables is important for the transition from fossil energy to using renewable energy sources, e.g. wind, solar and water. READ MORE

  5. 5. Carbon Emissions from Western Siberian Inland Waters

    Author : Svetlana Serikova; Jan Karlsson; Oleg S. Pokrovsky; Hjalmar Laudon; Peter Raymond; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

    Abstract : Inland waters (i.e. rivers, streams, lakes, ponds) emit carbon (C) into the atmosphere. The magnitude of global inland water C emission has been estimated to equal the global ocean C sink, thus making inland waters an important component of the global C cycle. READ MORE
