Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

BACKGROUND End-expiratory lung volume measurement by the nitrogen washin-washout technique (EELVWI-WO) may help titrating positive end-expiratory pressure (PEEP) during acute respiratory distress syndrome (ARDS). Validation of this technique has been previously performed using computed tomography (EELVCT), but at mild PEEP levels, and relatively low fraction of inspired oxygen (FiO2), which may...

The recent progress in application of nanostructures in electrochromic materials and devices is reviewed. ZnO nanowire array modified by viologen and WO₃, crystalline WO₃ nanoparticles and nanorods, mesoporous WO₃ and TiO₂, poly(3,4-ethylenedioxythiophene) nanotubes, Prussian blue nanoinks and nanostructures in switchable mirrors are reviewed. The electrochromic properties were significantly en...

Tungstated zirconia is a robust solid acid catalyst for light alkane (C(4)-C(8)) isomerization. Several structural models for catalytically active sites have been proposed, but the topic remains controversial, partly because of the absence of direct structural imaging information on the various supported WO(x) species. High-angle annular dark-field imaging of WO(3)/ZrO(2) catalysts in an aberra...


 Das Einzige, das Bestand hat, ist die Veränderung. Dieser Prozess war noch nie so schnell wie jetzt. Unsere Welt verändert sich im Minutentakt und macht es uns immer schwerer, einen Anker für unser Leben zu setzen. Darum umso wichtiger, den aktuellen Herausforderungen stellen, Lösungsansätze suchen in eigene Tun implementieren. Mit Techniken der Wo-bist-du-Frage oder Auseinandersetzung m...

Datenschutz ist zwar als Querschnittsmaterie bekannt, dies wird aber typischerweise so verstanden, dass er in allen Fachbereichen erforderlich ist, d.h. unabhängig von der konkreten Anwendung überall dort, wo personenbezogene Daten auftreten. Doch auch direkt im Softwareentwicklungsprozess kann Datenschutz als Querschnittsmaterie angesehen werden: In allen Phasen der Softwareerstellung sind spe...

HE locus of Woolly is in chromosome 2 of the tomato, Lycopersicon escuZentum, in which the basic chromosome number is 12. Three alleles, in addition to the normal non-Woolly allele, WO+, are known. WO and Wov are dominant and lethal when homozygous, and WO"' is partially dominant and viable when homozygous (RICK and BUTLER 1956). Woolly plants have thicker, longer trichomes than the normal and ...
