  1. 21. Low-angle estimation : Models, methods and bounds

    Författare :Katarina Boman; Peter Stoica; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Sammanfattning : In this work we study the performance of elevation estimators and lower bounds on the estimation error variance for a low angle target in a smooth sea scenario using an array antenna. The article is structured around some key assumptions on multipath knowledge, signal parameterization and noise covariance, giving the reader a framework in which Maximum Likelihood estimators exploiting different á priori information can be found.

  3. 22. Models for tracking in automotive safety systems

    Författare :Fredrik Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; active safety; vehicle tracking; Automotive; radar detections; preventive safety;

    Sammanfattning : This thesis treats the three main components of a tracking system: motion models, sensor models and implementation architecture. A tracking system utilizes models to extract as much information as possible from a set of sensors, with the purpose of estimating the state of a dynamic system. LÄS MER

  4. 23. Statistical inference with deep latent variable models

    Författare :Najmeh Abiri; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deep Learning; Generative Models; Variational Inference; Missing data; Imputation; Fysicumarkivet A:2019:Abiri;

    Sammanfattning : Finding a suitable way to represent information in a dataset is one of the fundamental problems in Artificial Intelligence. With limited labeled information, unsupervised learning algorithms help to discover useful representations. LÄS MER

  5. 24. Color Prediction and Separation Models in Printing : Minimizing the Colorimetric and Spectral Differences employing Multiple Characterization Curves

    Författare :Yuanyuan Qu; Sasan Gooran; Roger D. Hersch; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Color prediction models and color separation models are essential for print device characterization and calibration, from which the profiles used in color management systems are built up. Dot gain refers to the phenomenon in printing causing the printed ink dots appear bigger than their reference size in the original bitmap. LÄS MER

  7. 25. The Missing link : Business Models Lock-in in Sociotechnical Transitions

    Författare :Rami Darwish; Mats Engwall; Vinit Parida; KTH; []
    Nyckelord :Business Models; Sociotechnical Transitions; Lock-in; Resource Dependence; Industriell ekonomi och organisation; Industrial Economics and Management;

    Sammanfattning : Societal and environmental challenges present challenges for our current industrial systems. In order to respond to these difficulties, various alternative systems have been suggested, as they promise sustainability and increased societal quality of life enabled by innovative technologies.
