  1. 1. Spaceborne Synthetic Aperture Radar for Sea Ice Observations, Concentration and Dynamics

    University dissertation from Chalmers University of Technology

    Author : Anders Berg; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sea ice concentration; sea ice dynamics; sea ice monitoring; satellite; synthetic aperture radar; interferometry;

    Abstract : Spaceborne Synthetic Aperture Radar (SAR) is the primary choice for sea ice monitoring due to its all-weather, day-and-night capability and regular delivery of high resolution images. This thesis presents methods for estimation of sea ice concentration and drift, a multi-sensor study of Baltic Sea ice radar signatures and an interferometric study of landfast sea ice. READ MORE

  2. 2. Optimal Detectors for Transient Signal Families and Nonlinear Sensors Derivations and Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : This thesis is concerned with detection of transient signal families and detectors in nonlinear static sensor systems. The detection problems are treated within the framework of likelihood ratio based binary hypothesis testing. READ MORE

  3. 3. Planning and Provisioning Strategies for Optical Core Networks

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Ajmal Muhammad; Linköpings universitet.; Linköpings universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Optical communication networks are considered the main catalyst for the transformation of communication technology, and serve as the backbone of today's Internet. The inclusion of exciting technologies, such as, optical amplifiers, wavelength division multiplexing (WDM), and reconfigurable optical add/drop multiplexers (ROADM) in optical networks have made the cost of information transmission around the world negligible.

  4. 4. Estimation of Thrust and Health Parameters for Jet Engines

    University dissertation from Chalmers University of Technology

    Author : Mattias Henriksson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Automatic control; Signalbehandling; Signal processing; Gas turbine performance estimation; Thrust estimation; Gas path analysis; Kalman filtering; Reduced order observers;

    Abstract : An advanced turbofan engine control system would benefit from an accurate thrust and engine performance estimate. Unfortunately, there is to date no reliable in-flight thrust measurement sensors available. READ MORE

  5. 5. Energy Constrained Wireless Sensor Networks Communication Principles and Sensing Aspects

    University dissertation from Uppsala : Institutionen för teknikvetenskaper

    Author : Erik Björnemo; Uppsala universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Abstract : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. READ MORE
