As one of the most popular instant messaging applications on smart devices, mobile QQ contains kinds of user data which even includes the evidence information of important investigation, so forensic analysis for mobile QQ is significant. Aiming at this situation, at first, this paper introduced the basic information about Android system and mobile QQ, and the research status of forensic model and...
Beginning with the basic concept and connotation characteristics of equipment core maintenance capability, the paper puts forward a military-civil support tasks allocation method based on core maintenance capability, and discusses the significant methods to intensify core maintenance capability construction.
Recent advances in our group about graphene bioapplications are discussed. In particular, the functionalization of graphene and graphene oxide, biosensing and bioimaging by using graphene-based nanomaterials, and some fundamental studies of graphene and graphene oxide have been summarized.
Runoff that is time domain hydrological random variable should be time domain and non-stationary regionalized variables as the factors changes usually shows some trends. Universal Kriging method is one of main methods to deal with optimal valuation of non-stationary regionalized variables. The study builds time domain of universal Kriging forecast model based on geostatistics theory. Analyzing data...
A fast super-resolution reconstruction algorithm designed for license plate recognition is proposed in this paper. It uses a new reduced cost function to produce images of higher resolution from low resolution frame sequences. Computational cost required in this algorithm is much lower compared with other methods. The effectiveness of the proposed algorithm is demonstrated through blind reconstruction...
To overcome the adverse effect caused by shift and rotation in fingerprint matching, a new method for fingerprint minutia extraction is presented. Since the orientation field around the fingerprint core has a certain specific regularity, we extract the fingerprint reference point and reference direction based on the orientation field of the image. Then we take the reference point as the origin, and...
Spatial domain based super-resolution reconstruction techniques, which were designed for uncompressed video to produce high-resolution image or image sequences, may not work well when applied directly to compressed videos, especially to those with severe quantization errors. Here a reconstruction approach designed for videos or image sequences, which were compressed using DWT-based techniques, is...
