Abstract:
Techniques described herein are generally related to steganalysis of suspect media. Steganalysis techniques may include receiving instances of suspect media as input for steganalytic processing. A first set of quantized blocks of data elements may be identified within the media, with this first set of blocks being eligible to be embedded with steganographic data. A second set of quantized blocks of data elements may be identified within the media, with this second set of blocks being ineligible to be embedded with steganographic data. The steganalysis techniques may requantize the first and second blocks. In turn, these techniques may compare statistics resulting from requantizing the first block with statistics resulting from requantizing the second block. The steganalysis techniques may then assess whether the first block of data elements is embedded with steganographic features based on how the statistics of the second blocks compare with the statistics of the first blocks.
Abstract:
A halogen-free, flame retardant composition comprises thermoplastic polyurethane, olefin block copolymer, carbonyl-containing olefin polymer compatibilizer, and flame retardant package comprising bisphenol-A bis(diphenyl phosphate) and/or resorcinol bis(diphenyl phosphate), a nitrogen/phosphorus based, halogen-free flame retardant, and epoxidized novolac. The composition that will not only be processed easily to make a wire or cable sheath but also pass both the VW-1 flame retardancy test and the UL1581 heat deformation test at 150° C. exhibits good tensile and flexibility properties.
Abstract:
Methods for presenting files upon switching between system states and portable terminals are provided. The portable terminal comprising a first system platform and a second system platform, a state in which the presentation of the file is controlled by the first system platform being a first state, and a state in which the presentation of the file is controlled by the second system platform being a second state. The method comprising: detecting, by the first system platform in the first state, that a status of the file satisfies a preset condition; backuping, by the first system platform, the file for the second system platform; and switching to the second state, and continuing, by the second system platform, the presentation of the file based on the backup file. With the portable terminal of hybrid system architecture according to embodiments of the present invention, if the system state is switched while a file is being played, the switched-to system can continue presenting the file based on the backup file, according to the presentation progress before the system switching. In this way, it is possible to achieve a seamless presentation of the file before and after the switching, and thus improve user's experience.
