  2. 1. Characteristics of Vertical Forest Backscatter Profiles Measured using Radar Tomography

    Author : Patrik Bennet; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest remote sensing; L-band; above-ground biomass; P-band; vertical reflectivity profiles; radar tomography; temporal backscatter variations;

    Abstract : Forests are an integral part of the Earth’s climate system, having shaped the conditions of life throughout millions of years, but the coverage and conditions of forests are under rapid change. To monitor this change and predict the impact on climate, yearly global mapping of forest Above-Ground Biomass (AGB) is needed. READ MORE

  4. 2. Temporal Characteristics of Boreal Forest Radar Measurements

    Author : Albert Monteith; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; antenna array; Synthetic aperture radar; temporal coherence; tomography; backscatter; remote sensing;

    Abstract : Radar observations of forests are sensitive to seasonal changes, meteorological variables and variations in soil and tree water content. These phenomena cause temporal variations in radar measurements, limiting the accuracy of tree height and biomass estimates using radar data. READ MORE

  5. 3. Patient stratification and treatment effects in diseases with disturbed cardiac function

    Author : Gabriel Granåsen; Urban Wiklund; Frida Sandberg; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biostatistics; Heart rate variability; Cardiac amyloidosis; hypertrophic cardiomyopathy; cluster analysis; Echocardiography; Long QT syndrome; Pediatric; Statins; Coronary artery calcium; Computer tomography; Machine learning; Predictive modeling;

    Abstract : Background: Cardiovascular disease characteristics are often measured using a combination of different measurement modalities. By combining information from these modalities using statistical modelling we can gain additional knowledge about these diseases. READ MORE
