It is a challenging work to design tamper recovery schemes for digital speech signal. Briefly, there are two problems need to be solved. One is that the signals used to tamper recovery are difficult to generate and embed, and the second is that it’s hard to tamper location precisely for attacked speech signal. In this paper, compression and reconstruction(More)
The tolerance of plants to biotic and abiotic stresses could be improved by transforming with fungal resistance-related genes. In this study, the cDNA sequence (GenBank Acc. No. KP337939) of the resistance-related gene Hsp24 encoding the 24 kD heat shock protein was obtained from the biocontrol fungus Trichoderma asperellum ACCC30536. The promoter region of(More)
We present a toolbox for high-throughput screening of image-based Caenorhabditis elegans phenotypes. The image analysis algorithms measure morphological phenotypes in individual worms and are effective for a variety of assays and imaging systems. This WormToolbox is available through the open-source CellProfiler project and enables objective scoring of(More)
—In this study, near-field electrospinning (NFES) was used to fabricate PVDF (Polyvinylidene fluoride) piezoelectric nano-fibers mixed with additional multiwalled-carbon nanotubes (MWCNT). Both mechanical strength and piezoelectric characteristics of a single nano-fiber were discussed. NFES technology can be used to fabricate PVDF piezoelectric fibers with(More)
Project Description: This research investigates using the Selective Laser Sintering (SLS) process to fabricate three-dimensional complex parts for aerospace, biomedical and energy applications. The parts being fabricated include aerospace structural components from high temperature and ultra-high temperature materials (alumina and zirconium diboride), bone(More)
