This book provides a comprehensive study on the design throughout process-structure-property correlation of the cellular silica constructs with an emphasis on the influence of the porous architecture on intended foam properties with following features: i) Provides a technology featuring 118 figures and 22 tables aiding towards the design and fabrication of cellular ceramics with manual solution available; ii) Slurry based processing route involving the use of hydrophobized fused silica with two different foam stabilization routes, in amalgamation with direct foaming method (to generate porous...

Digital Right Management-Systeme (DRMs) verarbeiten Mediendaten in der Regel in komprimierter und verschlüsselter Form. Häufig ist es erforderlich, diese Medienelemente in der komprimierten verschlüsselten Domäne selbst mit einem Wasserzeichen zu versehen, um Manipulationen zu erkennen oder eine Eigentumserklärung oder Urheberrechtsverwaltung zu ermöglichen. Es ist eine Herausforderung, diese komprimierten, verschlüsselten Ströme mit einem Wasserzeichen zu versehen, da der Komprimierungsprozess die Informationen der Rohmedien in eine geringe Anzahl von Bits gepackt hätte und die...

Digital Right Management systems (DRMs) generally handle media data in a compressed and encrypted form. It is often necessary to watermark these media items in the compressed-encrypted domain itself for tamper detection or ownership declaration or copyright management purposes. It is a challenge to watermark these compressed encrypted streams as the compression process would have packed the information of raw media into a low number of bits and encryption would have randomized the compressed bit stream. Attempting to watermark such a randomized bit stream can cause a dramatic degradation of...
