“Elastic network interpolation (ENI)” generates a series of transitional conformations between two protein conformations by interpolating inter-atomic distances. A group of atoms that maintain their inter-atomic distances while moving concurrently in a protein is known as a rigid cluster; “rigid cluster ENI” is the interpolation of the rotations and translations of rigid clusters. Rank 3 positive...
Traditional time-domain adaptive filtering has limitation in signal detection and estimation under condition of low SNR. Therefore, a method of weak signal detection based on FRFT-domain adaptive filtering algorithm is presented. The method utilizes excellent features of FRFT(Fractional Fourier Transformation) specific to LFM signals, processes echo signals through adaptive filtering algorithm on...
TISCO is the earliest and the largest enterprise of stainless steel production in China. After continuous technical reconstruction, especially 500,000t stainless steel enlarging capacity reconstruction and 1.5 million tons of new stainless steel revamp project, stainless steel output reached 3 million tons. In recent years, a group of proprietary technology with independent intellectual property rights...
To date a couple of lossless data hiding methods have been developed. However, the pure payload is still a little low in those proposed schemes. To solve this problem, a lossless data hiding method based on pixel differences histogram for multilevel embedding is proposed in the paper, which utilizes multiple pairs of peak points to embed more data, and also alternates the scan order to achieve the...
Multistatic passive radar systems provide higher positioning accuracy comparing with the bistatic ones. However, the positioning performance of the multistatic passive radar systems is largely dependent on the geometry. Especially, it is difficult to designate transmitters from the given ones in a single frequency network (SFN) based passive radar system. Therefore the receiver location is of crucial...
In order to suppress the multi-path interference (MPI) in the DS CDMA system, a new RAKE receiver based on parallel interference elimination is first proposed in this paper: data symbol tentative decision is obtained by linear decision; the multi-path interference are evaluated by tentative decision and known user information. Then the performance over Rayleigh fading channel are analyzed and compared...
Path planning is an effective means to improve the operational effectiveness of aircrafts. A reasonable estimation and description of threats existing in operation space are significant before generating a specific path for an aircraft. To avoid depending on experts' experience excessively when we evaluate the threat situations, an index based threat modeling method named IBTMM is proposed. IBTMM...
MPPT (maximum power point tracking) is the main approach to improve efficiency of the PVGS (photovoltaic voltage grid system). Based on formula fuzzy control and adaptive an intelligent adaptive fuzzy control method is proposed in this paper. Its application can make the system restrain the overshoot and quickly track the MPP. Final experiments can prove its effects into improving efficiency, power...
