Images (typically JPEG) are used as evidence against cyber perpetrators. Typically the file is carved using standard patterns. Many concentrate on carving JPEG files and overlook the important of thumbnail in assisting forensic investigation. However, a new unique pattern is used to detect thumbnail/s and embedded JPEG file. This paper is to introduce a tool call PattrecCarv to recognize thumbn...

Abstract The adduct of Urea and Hydrogen Peroxide (UHP), also called Carbamide Peroxide, is industrially produced as a solid source hydrogen peroxide for bleaching, disinfection, oxidation reactions. As chemical combination fuel oxidiser, UHP has explosive potential but it unclear whether could sustain detonation at small scale. In the configuration we tested, succeeded in recording self‐sustai...

The geochronology of metasediments incorporated to orogenic wedges provides an important key in understanding the early evolution collisional systems. This study reveals timing Variscan processes Saxothuringian wedge, reflecting transition from oceanic continental subduction and collision. In situ monazite U-Pb Rare Earth Elements (REE) geochemistry were performed Erzgebirge Crystalline Complex...

Mutants of Escherichia coli defective in the hexose phosphate transport system were isolated. Negative selection by penicillin treatment or positive selection with phosphonomycin was employed. These mutants grew normally on all carbon sources other than hexose phosphates. The map location of the mutations in 18 independently isolated mutant strains was investigated by transduction crosses. All ...

Although donor-acceptor (0-A) recombination UHP emission in semiconductors is reasonably well un2O~ ~ T’l.2K derstoo&, the processes contributing to the photo0 ~ production of the 0°-A°generators have not been o 489nm adequately explored. The interplay among exciton and charge carrier roles results in different spatial and neutral-pair-separation distributions 9 10 which are manifested in the s...

Based on the old but famous distinction between"in the small"and"in the large"software development, at Nancy Universit\'e, UHP Nancy 1, we experience for a while software engineering education thanks to actual project engineering. This education method has the merit to enable students to discover and to overcome actual problems when faced to a large project which may be conducted by a large dev...
