    Evaluation of the angular coordinates in survey radar stations with subsystems for spatial noise compensation by S. V. Kozlov, Vu. Thanh Ha

    Published 2019-06-01
    “…Algorithms are based on intraperiod interference cancellation operations with «whitening» of their results in the time domain by dividing the sum of weighted internal noise by estimating the root-mean-square voltage value and uncompensated residuals of external interference, calculating the expected signal for all possible target positions within the uncertainty domain, constructing and maximizing the likelihood function in the form of the mutual correlation function of isolated implementation and the reference signal. …”

    Incremental clustering method based on Gaussian mixture model to identify malware family by Jianwei HU, Xin CHE, Man ZHOU, Yanpeng CUI

    Published 2019-06-01
    “…Aiming at the logical similarity of the behavioral characteristics of malware belonging to the same family,the characteristics of malware were extracted by tracking the logic rules of API function call from the perspective of behavior detection,and the static analysis and dynamic analysis methods were combined to analyze malicious behavior characteristics.In addition,according to the purpose,inheritance and diversity of the malware family,the transitive closure relationship of the malware family was constructed,and then the incremental clustering method based on Gaussian mixture model was improved to identify the malware family.Experiments show that the proposed method can not only save the storage space of malware detection,but also significantly improve the detection accuracy and recognition efficiency.…”

    Global dynamics of the chemostat with different removal rates and variable yields by Tewfik Sari, Frederic Mazenc

    Published 2011-05-01
    “…In this paper, we consider a competition model between $n$ species in a chemostat includingboth monotone and non-monotone growth functions, distinct removal rates and variable yields.We show that only the species with the lowest break-even concentration survives, provided that additional technicalconditions on the growth functions and yields are satisfied.We construct a Lyapunov function which reduces to the Lyapunov function used byS. …”

    Adaptive routing and wavelength assignment method based on SDN by Zhongnan ZHAO, Jian WANG, Hongwei GUO

    Published 2019-09-01
    “…Routing and wavelength assignment is an important resource allocation method of all-optical network.Aiming at the problem of traditional method combined with the new architecture,an adaptive multi-objective routing and wavelength assignment method based on SDN was proposed,which could realize the allocation of link resources of all-optical network through self-regulation.Based on the SDN service function chain model,service scheduling time and link service quality were taken as the scheduling objective,routing and wavelength assignment problem was constructed as the 0-1 integer programming problem,meanwhile,binary hybrid topology particle swarm optimization algorithm was used to optimize the network resources for optimal scheduling.The simulation results show that the proposed method is superior to the traditional classical algorithms in the test of recovery time,blocking rate and resource utilization.…”

    STRUCTURAL RELIABILITY OPTIMIZATION DESIGN OF REINFORCED SHELL MODEL BASED ON ADAPTIVE SURROGATE MODEL by LIU YuZhuo, CAO LiXiong, WU JianGuo, LI HaiBo

    Published 2024-01-01
    “…Reinforced shell structure is widely used in aerospace load-bearing structures because its high specific stiffness and specific strength.By considering the uncertainty and risk factors in the structural parameters,the Reliability-Based Design Optimization (RBDO) can avoid the overly conservative design of the structure and ensure its reliability and safety.An efficient RBDO method based on adaptive agent model was proposed.This method solves the problem of lightweight design of reinforced shell structure under buckling reliability constraints.The adaptive addition of sample points was implemented through the expected feasibility function criterion,and the discrete variables was continued by constructing piecewise functions.This increases optimization efficiency while ensuring the reliability of design results.Finally,the effectiveness of the proposed method is verified by comparing the RBDO results with the deterministic optimization results.…”

    Blind recognition of STBC-OFDM signals based on modified K-S test by Qing LING, Li-min ZHANG, Wen-jun YAN

    Published 2017-04-01
    “…Aiming at the problem that existed blind classification of STBC-OFDM in multiple input single output (MISO) communication system,an efficient method for blind classification of space-time block coded orthogonal frequency-division multiplexing (STBC-OFDM) signals based on modified Kolmogorov-Smirnov (K-S) test was proposed,when a single receiver antenna was employed at the receiver.Firstly,the model of received STBC-OFDM signals in MISO systems was given.Secondly,with the correlation of the coding matrix of STBC-OFDM signals,and the discrimination features function provided by the empirical cumulative distribution (CDFs) of the received OFDM blocks was constructed.Finally,the distance between CDFs was tested by the two-sample K-S test,which could blindly classify the STBC-OFDM signals.The proposed algorithm didn't need the estimation of channel,noise statistics and modulation type,and consequently,was well suited for non-cooperative communication context.Theoretical analysis and experimental verify its validity.…”
