  1. 1. Solar Wind and Geomagnetic Activity - Predictions Using Neural Networks

    Författare :Hans Gleisner; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; kosmisk kemi; rymdvetenskap; magnetosphere; solar wind; space weather; geomagnetic activity; geomagnetism; ring current; auroral electrojet; neural networks; forecasting; Astronomy; space research; Astronomi; cosmic chemistry; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Fysicumarkivet A:2000:Gleisner;

    Sammanfattning : This thesis shows how artificial neural networks (ANNs) can be applied to predict geomagnetic activity from solar-wind data. It introduces and summarizes five papers where development of ANN models are reported, and where predictions of geomagnetic activity are discussed. LÄS MER

  3. 2. Towards forecasting epigenetic repression

    Författare :Moa J. Lundkvist; Yuri B. Schwartz; Ludvig Lizana; Peter V. Kharchenko; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; epigenetics; Polycomb; PRC1; PRC2; H3K27 methylation; Monte-Carlo simulation; chromatin structure; Drosophila; molekylär bioteknik inst f molekylärbiologi ; molecular biotechnology dept of molecular biology ;

    Sammanfattning : Multicellular organisms form many different cell types from one genome, which requires differential gene activity. The Polycomb system upholds the correct gene expression programs by epigenetically silencing genes that encode critical transcription regulators. LÄS MER

  5. 4. Enhancing aftermarket demand planning with product-in-use data

    Författare :Joakim Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Big data; Digitalization; Product-in-use.; Forecasting; Demand planning; Aftermarket;

    Sammanfattning : Enhancing aftermarket demand planning with product-in-use data ABSTRACT Aftermarket demand planning, consisting of forecast and known demand, is a critical activity for both the uptime of customers’ products and the supply chain-related costs. Traditional aftermarket forecasting methods use historical demand as the only input to the statistically based forecasts, usually combined with judgmental modifications. LÄS MER

  7. 5. Context-aware Human Motion Prediction for Robots in Complex Dynamic Environments

    Författare :Andrey Rudenko; Kai Arras; Achim Lilienthal; Thierry Fraichard; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; robotics; human motion prediction; activity forecasting;

    Sammanfattning : Understanding human behavior is a key skill for intelligent systems that share physical and emotional spaces with humans. One of the main challenges to this end is the ability of such systems to make accurate predictions of human motion. LÄS MER
