  2. 21. 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

  4. 22. Applying Data Analytics to Freight Train Delays in Shunting Yards

    Author : Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; delay prediction; congestion; delay probability distributions; temporal delay distributions; Rangergodsbangårdarna; förseningsprediktion; trängsel; fördröjning av sannolikhetsdistributioner; tidsfördröjningsdistributioner; Transportsystem; Transport Systems;

    Abstract : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.

  5. 23. Entropy, information theory and spatial input-output analysis

    Author : David F. Batten; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Commodity flows; dynamic analysis; entropy; information theory; input-output analysis; probability distributions; regional and interregional modelling;

    Abstract : Interindustry transactions recorded at a macro level are simply summations of commodity shipment decisions taken at a micro level. The resulting statistical problem is to obtain minimally biased estimates of commodity flow distributions at the disaggregated level, given various forms of aggregated information. READ MORE

  6. 24. Reliability-based Assessment of Concrete Dam Stability

    Author : Marie Westberg; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; stability; concrete dam; structural reliability analysis; probability; uplift; system reliability;

    Abstract : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. READ MORE

  7. 25. The operating cycle representation of road transport missions

    Author : Luigi Romano; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; transport application; road mission; probability distributions; stochastic processes; energy estimation;

    Abstract : The difficulties that conventionally road vehicles are facing in meeting regulation standards require ad-hoc solutions. Moreover, the impellent shift of paradigm towards full electrification and partial automation is posing great challenges to the automotive industry, which has set a zero-emissions target to be reached within a short time horizon.
