Higher-order expansions of powered extremes of logarithmic general error distribution

In this paper,Let M_(n)denote the maximum of logarithmic general error distribution with parameter v≥1.Higher-order expansions for distributions of powered extremes M_(n)^(p)are derived under an optimal choice of normalizing constants.It is shown that M_(n)^(p),when v=1,converges to the Frechet extreme value distribution at the rate of 1/n,and if v>1 then M_(n)^(p)converges to the Gumbel extreme value distribution at the rate of(loglogn)^(2)=(log n)^(1-1/v).

THE LOGARITHMIC SOBOLEV INEQUALITY FOR A SUBMANIFOLD IN MANIFOLDS WITH ASYMPTOTICALLY NONNEGATIVE SECTIONAL CURVATURE

Global Existence and Decay of Solutions for a Class of a Pseudo-Parabolic Equation with Singular Potential and Logarithmic Nonlocal Source

This article investigates the well posedness and asymptotic behavior of Neumann initial boundary value problems for a class of pseudo-parabolic equations with singular potential and logarithmic nonlinearity. By utilizing cut-off techniques and combining with the Faedo Galerkin approximation method, local solvability was established. Based on the potential well method and Hardy Sobolev inequality, derive the global existence of the solution. In addition, we also obtained the results of decay.

Existence of a Sigh-Changing Solution Result for Logarithmic Schrödinger Equations with Weight Function

This paper is devoted to studying the existence of solutions for the following logarithmic Schrödinger problem: −div(a(x)∇u)+V(x)u=ulogu2+k(x)| u |q1−2u+h(x)| u |q2−2u, x∈ℝN.(1)We first prove that the corresponding functional I belongs to C1(HV1(ℝN),ℝ). Furthermore, by using the variational method, we prove the existence of a sigh-changing solution to problem (1).

基于Logarithmic方程的干燥参数对稻谷水分扩散特性影响分析

稻谷籽粒内部水分扩散的快慢决定了干燥速率。本文基于Logarithmic方程,建立稻谷水分传递动力学模型,并分析热风温度(40、50、60、70℃)和风速(0.3、0.4、0.5 m/s)对稻谷(湿基水分含量23.4%)有效水分扩散系数和扩散活化能的影响。结果表明:随着干燥温度和风速的上升,稻谷干燥速率提高,同时对应的有效水分扩散系数越大,分别为5.123×10-12~2.141×10-11m^2/s;扩散活化能从32.94 k J/mol增加至36.30 k J/mol;对比常用的5种谷物干燥模型发现,Logarithmic模型对稻谷薄层干燥的拟合度较好,R2>0.997,RMSE<2.810×10^(-3),同时该模型模拟得出的有效水分扩散系数与实际差值均低于3.8×10^(-13)m^2/s,扩散活化能均低于2.53 k J/mol,与实际值基本吻合。

乔伊斯的短篇A Little Cloud标题之评析

A Little Cloud是爱尔兰现代派小说家詹姆斯.乔伊斯(James Joyce)的一部短篇小说。长期以来,小说的标题A Little Cloud如乔伊斯的写作风格一样,云遮雾障,令人费解。人们根据自身的理解与联想,对该标题作了不同的翻译与阐释,但普遍认为“a little cloud”意指“天上的一小片云”,象征着生活的甘霖。笔者通过诸多研究与论证,最终得出:a little cloud意指“一个小烟圈”,象征着主人公从最初的“精神瘫痪”到希冀到快乐,直至希望破灭而最后顿悟(epiphany)的整个过程。

基于Littlewood-Paley小波支持向量机的故障诊断

提出一种基于Littlewood-Paley小波支持向量机(LPWSVM)的旋转机械故障诊断模型。首先将故障信号EMD分解为平稳IMF分量,再选择表征故障调制特征的IMF分量并构造瞬时幅值Shannon熵作为故障特征矢量输入到LPWSVM中进行故障识别。EMD分解可自适应分离故障调制信号;瞬时幅值Shannon熵矢量的不同拉大了各类故障的互异性;Littlewood-Paley小波核是一种具有平移正交性的多维允许支持向量核函数,可以其正交性逼近二次可积空间上的任意函数,具有良好的作线性映射能力,因而LPWSVM在同等条件下比一般最小二乘支持向量机的学习精度和自适应识别能力要高,更适用于故障诊断等复杂模式识别问题。一个滚动轴承故障诊断实例说明该模型的有效性。
