    Statistical Antenna Proximity Effect Modeling with Uncertainty Impedance Ellipses by Pedro Luis Carro, Jesús de Mingo, Paloma García-Dúcar, Antonio Valdovinos

    Published 2017-01-01
    “…In this paper, we investigate the influence of the user on the input impedance by means of a new statistical approach which relies on uncertainty, where a handheld antenna works in two modes (data and talk) while people couple to the antenna. …”

    Port scan detection algorithms based on statistical traffic features

    Published 2007-01-01
    “…A slowly port scan detect method was presented based on the statistical traffic features.Two statistical features: the ratio between the number of hosts and ports a host communicates and similarities of the ports set,were selected to denote the traffic features.The CUSUM and wavelet transform methods were employed to analyze the features and detect the slowly port scan behaviors.The experimental results show that the methods proposed detect port scan behaviors effi-ciently and correctly,it has low false negative and false positive alarm rate compared with the Snort.…”

    Statistical Downscaling Method for Vegetation Optical Depth Based on NDVI by Wang Xinyu, Fang Shibo, Han Jiahao

    Published 2025-01-01
    “…One involves integrating active microwave remote sensing, while the other involves integrating optical remote sensing.Currently, there is limited research focused on downscaling VOD, particularly using optical vegetation indices, which is very uncommon.Thus, statistical methods can be employed in conjunction with NDVI to spatially downscale VOD, exploring the feasibility of using optical remote sensing data for VOD downscaling. …”

    Dynamic Modeling and Optimal Control for Complex Systems with Statistical Trajectory by Lingli Guo, Zhengguang Xu, Ye Wang

    Published 2015-01-01
    “…This paper is concerned with the problem of the working state class dynamic modeling and control of the complex system with statistical trajectory. Firstly, a novel discrete-time nonlinear working state class dynamic mathematical model of sintering machine is constructed by K-means cluster method for the local data, which overcomes difficulties of modeling by mechanism and describes the class change against the point movement. …”

    Geometrical statistical channel model with an Inverted-Parabolic spatial distribution by Jie ZHOU, Dong-dong XU, Kikuchi HISAKAZU

    Published 2014-03-01
    “…,a proper geometrical statistical channel model was proposed with inverted-parabolic spatial distribution around mobile station(MS) by using geometric partitioning method.Closed-form expressions for probability density functions(PDF) of AOA ,TOA and DS in the outdoor macrocell and microcell wireless environments were derived.Compared with the uniform and Gaussian scatter density model,the observed results consist with previous theory and experience.In addition,the Doppler spectra at the MS was also presented and the Clarke U-shaped model was modified.Employing the channel model,the effect of directional antenna was analyzed with the main-lobe width 2α at the BS and D/R and φ .v…”
