A popular self-normalization (SN) approach in time series analysis uses the variance of a partial sum as a self-normalizer. This is known to be sensitive to irregularities such as persistent autocorre...
基于广义的Huygens-Fresnel原理和非Kolmogorov谱模型,推导了无线光通信系统中径向分布部分相干高斯-谢尔模型阵列光束在非Kolmogorov大气湍流中传输时瑞利区间zR和湍流距离zT的解析表达式,对瑞利区间和湍流距离随湍流参量和光束参量的变化情况进行了数值分析.结果表明:不论是相干还是非相干合成,径向分布部分相干高斯-谢尔模型阵列光束的zR和zT均随湍流广义指数α的增大非单调变...
In this paper, we carry out a detailed mathematical study of two theoretical distinguishers based on the Kolmogorov-Smirnov (KS) distance. This includes a proof of soundness and the derivation of cl...
基于广义惠更斯-菲涅尔原理,采用Rytov方法推导了径向分布高斯阵列光束在非Kolmogorov湍流大气中传输时的光强闪烁指数表达式,分析了径向半径r0、光束个数N、广义指数α及传输距离L对轴上和离轴闪烁指数的影响。结果表明:轴上和离轴闪烁指数随着α的增加均先增大后减小,值得注意的是不同的r0光束的闪烁指数达到极大值所对应的α略有不同,轴上闪烁指数随着r0的增大达到极大值所对应的α呈减小趋势,而离...
近期,中国科学院合肥物质科学研究院安徽光学精密机械研究所大气光学研究中心研究员朱文越课题组提出非Kolmogorov湍流折射率结构常数的等效方法,该方法建立了Kolmogorov湍流折射率结构常数与非Kolmogorov湍流折射率结构常数之间的等效关系,这一成果发表在美国光学学会(OSA)近期出版的optics express (2015,23(18),23004-23012)...
In this paper we will give a proof of Kolmogorov’s theorem on the conservation of invariant tori. This proof is close to the one given by Bennettin, Galgani, Giorgilli and Strelcyn in [2]; we follow t...
where K(Y ) denotes the length of the shortest computer program that can compute the finite-precision n-vector Y . In words, this is the simplest object that fits the data to within the ...
Shannon’s Rate-Distortion Theory describes the number of bits needed to approximately represent typical realizations of a stochastic process X = (X(t) : t ∈ T),while Kolmogorov’s -entropy describes...
As long as vorticity quantization remains irrelevant for long-wave physics, superfluid turbulence supports a regime macroscopically identical to the Kolmogorov cascade of a normal liquid. At high enou...
基于Rytov近似和Huygens-Fresnel原理, 推导出外差激光雷达在non-Kolmogorov弱湍流中斜程探测时目标平面的平均光强和闪烁指数, 得到外差激光雷达系统效率, 并针对广义指数、天顶角、结构常量、基站结构、望远镜孔径和光束类型对系统效率的影响进行了研究.研究结果表明:当广义指数小于3.2或大于3.8时, 外差激光雷达的系统效率减小幅度较大;随着天顶角的增大系统效率逐渐减小;双...
Generic side-channel distinguishers aim at revealing the correct key embedded in cryptographic modules even when few assumptions can be made about their physical leakages. In this context, Kolmogorov-...
Can complexity classes be characterized in terms of efficient reducibility to the (undecidable) set of Kolmogorov-random strings? Although this might seem improbable, a series of papers has recently p...
Accurate Goodness of Fit tests for the extreme tails of empirical distributions is a very im-portant issue, relevant in many contexts, including geophysics, insurance and finance. We have derived exac...
The conditional in conditional Kolmogorov complexity commonly is taken to be a finite binary string. The Coding Theorem of L.A. Levin connects unconditional prefix Kolmogorov complexity with the discr...
We study the dependence of the Kolmogorov widths of a compact set on the ambient Banach space.
