  2. 21. Geometric Discretization in Shape analysis

    Author : Erik Jansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; compressible fluids; diffeomorphisms; residual neural networks; quantization; machine learning; Shape analysis;

    Abstract : Discretizations in shape analysis is the main theme of this licentiate thesis, which comprises two papers.  The first paper considers  the problem of finding a parameterized time-dependent vector field that warps an initial set of points to a target set of points. READ MORE

  4. 22. Input-Output Stability Analysis of Networked Control Systems

    Author : Johannes Nygren; Kristiaan Pelckmans; Torkel Glad; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; L2-stability; quantization; delay; packet dropouts; switching systems; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). READ MORE

  5. 23. Low-delay sensing and transmission in wireless sensor networks

    Author : Johannes Karlsson; Mikael Skoglund; Markus Flierl; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative communication; wireless sensor networks; low-delay transmission; joint source-channel coding; estimation; quantization; Telecommunication; Telekommunikation;

    Abstract : With the increasing popularity and relevance of ad-hoc wireless sensor networks, cooperative transmission is more relevant than ever. In this thesis, we consider methods for optimization of cooperative transmission schemes in wireless sensor networks. READ MORE

  7. 25. Massive Multi-Antenna Communications with Low-Resolution Data Converters

    Author : Sven Jacobsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; orthogonal frequency-division multiplexing; channel estimation; quantization; linear precoding; convex optimization; nonlinear precoding; linear combing; hardware impairments; analog-to-digital converter; beamforming; Massive multi-user multiple-input multiple-output; digital-to-analog converter;

    Abstract : Massive multi-user (MU) multiple-input multiple-output (MIMO) will be a core technology in future cellular communication systems. In massive MU-MIMO systems, the number of antennas at the base station (BS) is scaled up by several orders of magnitude compared to traditional multi-antenna systems with the goals of enabling large gains in capacity and energy efficiency.
