  2. 1. On the Military Utility of Spectral Design in Signature Management : a Systems Approach

    Author : Kent Andersson; Jouko Vankka; Gunnar Hult; Hans Kariis; Hans Liwång; Harold Lawson; Jari Hartikainen; Försvarshögskolan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; military utility; survivability; signature management; systems engineering; camouflage; Low Observable Technology; spectral design; multi-spectral; Försvarssystem; Military Technology;

    Abstract : There is an ongoing duel between military sensor development and developments in signature management. The last decade, with warfare characterized by joint expeditionary operations and asymmetry, has favored sensors. READ MORE

  4. 2. Plasmonic Nanospectrocopy of Individual Nanoparticles - Studies of Metal-Hydrogen Interactions and Catalysis

    Author : Svetlana Alekseeva; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; grain boundary; metal-hydrogen interactions; plasmonic sensors; single particle spectroscopy; palladium nanoparticles and nanocrystals; localized surface plasmon resonance; hole-mask colloidal lithography; nanocatalysts; shrinking-hole colloidal lithography; plasmonic nanospectroscopy; dark field scattering spectroscopy; nanoscale effects;

    Abstract : Localized surface plasmon resonance (LSPR) is the phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light used for the excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. READ MORE

  6. 4. Implication of chemical deterioration on mechanical performance of wood

    Author : Shahin Norbakhsh; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The oak wood of the 17th century warship Vasa has shown significant changes in the chemical and mechanical properties as compared to recent oak. The most important factors contributing to these changes are the incorporation of iron compounds during waterlogging and the uptake of polyethylene glycol (PEG) in the course of the preservation treatment.

  7. 5. Key Technologies in Low-cost Integrated Vehicle Navigation Systems

    Author : Yueming Zhao; Lars E. Sjöberg; Milan Horemuž; Hossein Nahavandchi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; INS; MEMS; error modelling; integration structure; lane detection; camera motion; balance adjustment; sensor array;

    Abstract : Vehicle navigation systems incorporate on-board sensors/signal receivers and provide necessary positioning and guidance information for land, marine, airborne and space vehicles. Among different navigation solutions, the Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. READ MORE
