  1. 1. Adaptable Semi-Automated 3D Segmentation Using Deep Learning with Spatial Slice Propagation

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Niels Agerskov; [2019]
    Keywords : Deep learning; spatial propagation; image segmentation; semi-automated;

    Abstract : Even with the recent advances of deep learning pushing the field of medical image analysis further than ever before, progress is still slow due to limited availability of annotated data. There are multiple reasons for this, but perhaps the most prominent one is the amount of time manual annotation of medical images takes. READ MORE

  2. 2. Projecting invasive species using remote sensing and spatial explicit models

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Astrid Zimmermann; [2018]
    Keywords : Physical Geography; Ecosystem Analysis; Rosa rugosa; invasive species; aerial images; growth rate; modeling; cellular automata; Earth and Environmental Sciences;

    Abstract : An evaluation of the current and previous Rosa rugosa growth on Kieler Ort, Germany, with the aim to predict the rose coverage in future, under consideration of environmental factors. Kieler Ort, a rather isolated island in the southwest Baltic Sea is representing a unique environment which is protected for its landscape, nature, flora and fauna and serves as a bird sanctuary.

    Author : Mengqiao di; [2018]
    Keywords : Ultrasound Optical Tomography; Deep Tissue Imaging; Monte Carlo Simulation; Spectral Hole Burning; Physics and Astronomy;

    Abstract : Ultrasound Optical Tomography (UOT) is a proposed technique, which combines ultrasound imaging and optical imaging in a new way to detect, e.g. READ MORE

  4. 4. Beamforming in LTE FDD for Multiple Antenna Systems

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Atef Hatahet; Ankit Jain; [2018]
    Keywords : Beamforming; FDD; MIMO; LTE; AOA; Technology and Engineering;

    Abstract : High data rate is still the most crucial factor in cellular systems, and with 5g approaching new techniques are studied to achieve higher bit rates. Using MIMO technology, the spatial domain was exploited through beamforming and multiplexing multiple users’ data together assured more spectrum efficiency which resulted in higher bit rates.

  5. 5. A 3D-model for O2 airglow perturbations induced by gravity waves in the upper mesosphere

    University essay from Chalmers tekniska högskola/Institutionen för rymd- och geovetenskap

    Author : Anqi Li; [2017]
    Keywords : MATS; internal gravity wave; mesosphere; O2 airglow;

    Abstract : To investigate the influence of atmospheric waves in the mesosphere, a new Swedishsatellite MATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) willbe launched in 2019. It will observe infrared emissions at 762 nm from the O2(b1+g )airglow in the region of 70 - 110 km altitude. READ MORE
