  2. 21. Modeling, Control and Protection of Low-Voltage DC Microgrids

    Author : Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

    Abstract : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. READ MORE

  6. 24. Distribution patterns of fleshy-fruited woody plants at local and regional scales

    Author : Matilda Arnell; Ove Eriksson; Johan Ehrlén; Sara A.O. Cousins; Angela Moles; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fleshy fruits; woody plants; dispersal; distribution patterns; range filling; dispersal limitation; historical land use; spatial associations; point-pattern analysis; recruitment; reproduction; pollination; fruit set; fruit-removal; Daphne mezereum; Plant Ecology; växtekologi;

    Abstract : Fleshy-fruited woody plants share a long history with humans, providing us with food and wood material. Because of this relation, we have actively moved some of these plants across landscapes and continents. READ MORE

  7. 25. Bayesian Modeling of Directional Data with Acoustic and Other Applications

    Author : Jalil Taghia; Arne Leijon; W. Bastiaan Kleijn; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE
