  2. 6. Low Frequency Acoustic Excitation and Laser Sensing of Vibration as a Tool for Remote Characterization of Thin Sheets

    Author : Etienne Mfoumou; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nondestructive testing; remote acoustics; slow dynamics; nonequilibrium dynamics; resonance frequency; material characterization; vibration-based technique; fracture toughness;

    Abstract : There is a need to monitor the existence and effects of damage in structural materials. Bulk components provide a much publicized example, but the need exists in a variety of other structures, such as layered materials used in food packaging industries. READ MORE

  4. 7. Towards Automation in Digital Investigations : Seeking Efficiency in Digital Forensics in Mobile and Cloud Environments

    Author : Irvin Homem; Theo Kanter; Panagiotis Papapetrou; Rahim Rahmani; Fredrik Björck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer forensics; network forensics; mobile devices; mobile forensics; cloud computing; semantic web; hypervisors; virtualization; remote acquisition; automation; evidence analysis; correlation; P2P; bittorrent; datalogi; Computer Science; informationssäkerhet; Information Systems Security;

    Abstract : Cybercrime and related malicious activity in our increasingly digital world has become more prevalent and sophisticated, evading traditional security mechanisms. Digital forensics has been proposed to help investigate, understand and eventually mitigate such attacks. READ MORE

  5. 8. High-­resolution mapping of soil organic carbon storage and soil properties in Siberian periglacial terrain

    Author : Matthias Siewert; Gustaf Hugelius; Mats Olsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil organic carbon; Siberia; remote sensing; ecosystems; Physical Geography; naturgeografi;

    Abstract : In the past years considerable attention has been given to soil organic carbon (SOC) stored in permafrost-affected soils in periglacial terrain. Studies have shown that these soils store around half the global SOC pool, making them a key component of the global carbon cycle. READ MORE

  6. 9. Glacier-Ocean Interactions in the Arctic : Contemporary calving and frontal melt from field observations, remote sensing, and numerical modelling

    Author : Felicity Alice Holmes; Nina Kirchner; Benedict T. I. Reinardy; Riko Noormets; Jason Briner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Glacier-ocean interactions; Arctic; Calving; naturgeografi; Physical Geography;

    Abstract : Globally, glaciers are losing mass as a result of the changing climate, with this mass loss having a considerable societal impact through rising sea levels. Glaciers which terminate in the oceans are particularly vulnerable to changing external conditions as a result of high sensitivity at their marine margins. READ MORE

  7. 10. Digital Beamforming Focal Plane Arrays for Radio Astronomy and Space-Borne Passive Remote Sensing

    Author : Oleg Iupikov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; spaceborne radiometers; radio telescopes; phased array feeds; reflector antenna feeds; feed-reflector interaction;

    Abstract : Dense Phased Array Feeds (PAFs) for reflector antennas have numerous advantages over traditional cluster feeds of horns in a one-horn-per-beam configuration, especially in RF-imaging applications which require multiple simultaneously formed and closely overlapping beams. However, the accurate analysis and design of such PAF systems represents a challenging problem, both from an EM-modeling and beamforming optimization point of view. READ MORE
