  1. 1. Bayesian Modeling of Directional Data with Acoustic and Other Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jalil Taghia; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  2. 2. On-line Mobile in situ Gamma Spectrometry

    University dissertation from Radiation Physics, Lund

    Author : Thomas Hjerpe; Lunds universitet.; Lund University.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Kärnfysik; Nuclear physics; radiation protection.; 137Cs; peak-to-valley method; depth distribution; orphan source search; orphan sources; emergency preparedness; mobile gamma spectrometry; nuclear accidents; Nuclear medicine; radiobiology; Nukleärmedicin;

    Abstract : Popular Abstract in Swedish I beredskapen för kärnolyckor är mobila in situ gammaspektrometriska mätningar ett viktigt redskap; vilket betyder att mätinstrument placeras i ett fordon (tex bil, flygplan eller helikopter) och gammastrålningen från omgivningen mäts under körning. I detta arbete har strategier och analysmetoder för två olika användningsområden utvecklats: 1) sökning av försvunna radioaktiva strålkällor, så kallade herrelösa källor (eng. READ MORE

  3. 3. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation

    University dissertation from Radiation Physics, Lund

    Author : Ferry Viawan; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distance protection; stochastic assessment; voltage dip; line drop compensation; distribution systems; on-load tap changer; overcurrent protection; sensitive equipment; voltage dip immunity; voltage control; short circuit; reactive power control; pilot protection.; protection coordination; protection; Distributed Generation; losses;

    Abstract : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. READ MORE

  4. 4. Planning Models for Single Wire Earth Return Power Distribution Networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Geofrey Bakkabulindi; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural electrification; power distribution planning; Single Wire Earth Return; distribution power flow; power system modeling; SRA - Energy; SRA - Energi;

    Abstract : The high cost of grid extension to rural areas, often characterized by scattered communities with low load densities, requires the use of low cost electrification technologies to ensure economic viability. In Single Wire Earth Return (SWER) power distribution networks, the earth itself forms the current return path of the single phase system leading to significant cost savings on conductors, poles and poletop hardware compared to conventional systems.

  5. 5. Trade, Knowledge and Income Distribution

    University dissertation from Jönköping : Jönköping International Business School

    Author : Helena Bohman; Högskolan i Jönköping.; [2008]
    Keywords : ;

    Abstract : This thesis consists of four independent essays which address two main areas of research. The first area deals with the role of income distribution in economic transactions. The first paper in the thesis, Knowing me, Knowing you, suggests a new method of incorporating income distribution into international trade analysis. READ MORE
