Hypersemilattice Strongly Regular Relationson Ordered Semihypergroups

In this paper, we ?rst consider the regular and strongly regular relations on ordered semihypergroups in detail. In particular, we introduce the concepts of the hypersemilattice strongly regular relations and complete hypersemilattice strongly regular relations on ordered semihypergroups, and investigate their related properties.Furthermore, the properties of hyper?lters of an ordered semihypergroup are studied,and several related applications are given. Especially, we prove that the equivalence relation N on an ordered semihypergroup S is the least complete hypersemilattice strongly regular relation on S.

Continuity of Solution Mappings for Parametric Set Optimization Problems under Partial Order Relations

This paper mainly investigates the semicontinuity of solution mappings for set optimization problems under a partial order set relation instead of upper and lower set less order relations. To this end, we propose two types of monotonicity definition for the set-valued mapping introduced by two nonlinear scalarization functions which are presented by these partial order relations. Then, we give some sufficient conditions for the semicontinuity and closedness of solution mappings for parametric set optimization problems. The results presented in this paper are new and extend the main results given by some authors in the literature.

On Relations for Moments of Generalized Order Statistics for Lindley–Weibull Distribution

Moments of generalized order statistics appear in several areas of science and engineering.These moments are useful in studying properties of the random variables which are arranged in increasing order of importance,for example,time to failure of a computer system.The computation of these moments is sometimes very tedious and hence some algorithms are required.One algorithm is to use a recursive method of computation of these moments and is very useful as it provides the basis to compute higher moments of generalized order statistics from the corresponding lower-order moments.Generalized order statistics pro-vides several models of ordered data as a special case.The moments of general-ized order statistics also provide moments of order statistics and record values as a special case.In this research,the recurrence relations for single,product,inverse and ratio moments of generalized order statistics will be obtained for Lindley–Weibull distribution.These relations will be helpful for obtained moments of gen-eralized order statistics from Lindley–Weibull distribution recursively.Special cases of the recurrence relations will also be obtained.Some characterizations of the distribution will also be obtained by using moments of generalized order statistics.These relations for moments and characterizations can be used in differ-ent areas of computer sciences where data is arranged in increasing order.

Higher-order squeezing of quantum field and higher-order uncertainty relations in non-degenerate four-wave mixing

It is found that the field of the combined mode of the probe wave and the phase conjugate wave in the process of non-degenerate four-wave mixing exhibits higher-order squeezing to all even orders. The higher-order squeezed parameter and squeezed limit due to the modulation frequency are investigated. The smaller the modulation frequency is, the stronger the degree of higher-order squeezing becomes. Furthermore, the hlgher-order uncertainty relations in the process of non-degenerate four-wave mixing are presented for the first time. The product of higher-order noise moments is related to even order number N and the length L of the medium.

Heat transfer of nanofluids considering nanoparticle migration and second-order slip velocity

The heat transfer of a magnetohydrodynamics nanofluid inside an annulus considering the second-order slip condition and nanoparticle migration is theoret-ically investigated. A second-order slip condition, which appropriately represents the non-equilibrium region near the interface, is prescribed rather than the no-slip condition and the linear Navier slip condition. To impose different temperature gradients, the outer wall is subjected to q2, the inner wall is subjected to q1, and q1 〉 q2. A modified two-component four-equation non-homogeneous equilibrium model is employed for the nanofiuid, which have been reduced to two-point ordinary boundary value differential equations in the consideration of the thermally and hydrodynamically fully developed flow. The homotopy analysis method （HAM） is employed to solve the equations, and the h-curves are plotted to verify the accuracy and efficiency of the solutions. Moreover, the effects of the physical factors on the flow and heat transfer are discussed in detail, and the semi-analytical relation between NUB and NBT is obtained.

Orders of Automorphism Groups of Some p-Groups

The orders of automorphism groups of the groups of order p^6 in the twelve family Ф12 axe produced, where p is an odd prime. Every group is analysed by utilizing the properties of metabelian, regularity and p-commutativity of finite p-groups, and the structure of the generators of its automorphism groups is obtained. Then the orders of automorphism groups are determined through some properties of equivalence in number theory.

On Moment Generating Function of Generalized Order Statistics from Erlang-Truncated Exponential Distribution

In this paper explicit expressions and some recurrence relations are derived for marginal and joint moment generating functions of generalized order statistics from Erlang-truncated exponential distribution. The results for k-th record values and order statistics are deduced from the relations derived. Further, a characterizing result of this distribution on using the conditional expectation of function of generalized order statistics is discussed.

Quality oriented multimode processes monitoring based on a novel hierarchical common and specific structure with different order information

Due to higher demands on product diversity,flexible shift between productions of different products in one equipment becomes a popular solution,resulting in existence of multiple operation modes in a single process.In order to handle such multi-mode process,a novel double-layer structure is proposed and the original data are decomposed into common and specific characteristics according to the relationship between variables among each mode.In addition,both low and high order information are considered in each layer.The common and specific information within each mode can be captured and separated into several subspaces according to the different order information.The performance of the proposed method is further validated through a numerical example and the Tennessee Eastman(TE)benchmark.Compared with previous methods,superiority of the proposed method is validated by the better monitoring results.

A Study on Order Reconstruction via Dialogue in The Joy Luck Club

While much research on The Joy Luck Club has been studied through grand lens,like feminism,or cultural factors,trauma,etc.,little research has been conducted to highlight self-consciousness and conflicts that are reflected in their seemingly endless dialogues between the four mothers and their daughters throughout the novel.Using dialogue from Bakhtin’s polyphony theory,the present study investigates precisely how it works to awaken self-consciousness in all of them;how their understanding and connection are restored,and eventually how exactly right decisions are made for their daughters in marriage.The findings show that,after numerous dialogues between mothers and daughters,their self-awareness has become clearer,their relations are mended,the right decisions are made,and eventually the order in every aspect is reconstructed.The study calls for greater attention to the embodiment of dialogues in The Joy Luck Club,and how they work effectively and profoundly at every level,and at last how they fulfill the reconstruction of orders in certain aspects.

Study about the Acquisition of the English Relative Clauses for Chinese Middle School Students

In recent four decades, relative clause has interested many scholars due to its unique structural complexity. This articletook Chinese senior high school students as subjects and found their acquisition order of relative clauses fully coincided with Ku-no’s Perceptual Difficulty Hypothesis but partly agreed with Keenan&Comire’s Noun Phrase Accessibility Hypothesis and Hamil-ton’s SO Hierarchal Hypothesis, which can provide implications and references for the English relative clauses’ learning andteaching.

资源下乡背景下乡村关系的差序格局及其形塑逻辑

以“一乡−多村”为乡村关系的两个主体,突破过去将乡村关系中的“村”视为一个抽象整体的研究进路,提出“乡村关系的差序格局”。在“行政消解自治”乡村一体化的背景下,乡镇与其下辖的各行政村的关系存在“亲疏远近”之别。形塑这种亲疏远近的要素主要有三个:一是特定行政村在中央或地方涉农政策中的重要性。政策性位置越突出,其与乡镇的关系越亲近。二是特定行政村村治情况良善与否。村干部治村能力越强,其与乡镇的关系越亲近。三是特定行政村在体制内有无先赋性外联关系。这种外联关系越重要,其与乡镇的关系越亲近。自上而下的各类资源在各行政村之间的配置,相应由乡村关系的差序格局来形塑。

美国政治极化与亚太战略风险

政治极化,特别是民主、共和两党的党争极化,是当前美国政治的突出现象。美国民主、共和两党不仅在意识形态取向和重大国内外政策上分歧严重,双方对对方的“情感温度”也急剧下降。美国的极化政治波及对外政策的制定,导致其对外政策缺乏连贯性,过分夸大外部威胁,且过分强调美国优先。极化政治下的美国对外政策,不仅可能加剧中美对抗风险,也会给亚太地区的和平、稳定与繁荣蒙上阴影。

“印太战略”框架下澳越关系的发展及影响

在“印太战略”框架下,近年来澳越两国关系不断升级,双方合作全面推进,两国尤其强化了在防务安全领域的合作和南海问题上的战略协调。澳大利亚希望借助与越南关系的升级提升地区影响力和彰显中等强国地位;越南则希望在南海问题上获得澳大利亚的支持。澳越关系的深化对南海局势及亚太地区秩序的稳定都将产生一定的影响。在推进两国合作制衡中国的战略盘算和应对所谓“中国威胁”的共识下,澳越两国关系将会继续深化,尤其是海洋安全领域的合作将会是两国关系的主要内容。为了维护南海局势和地区秩序的稳定,中国和东盟国家要相向而行,尽力排除域外国家介入南海争端,构建中国和东盟国家共同主导的南海地区秩序。

基于TOPSIS和GRA的信息安全风险评估

信息安全风险评估是一项非常重要的信息安全保障活动.依据信息安全相关标准,可从资产、威胁和脆弱性3方面识别出重要的风险因素,并确定相应的信息安全风险评估指标.参考等保2.0确定风险评估指标是一种可行的方法.在进行信息安全风险评估时,采用熵权法进行客观的指标赋权,并结合优劣解距离法(technique for order preference by similarity to ideal solution,TOPSIS)和灰色关联分析(grey relational analysis,GRA)进行综合评估.实例分析表明,依据信息熵进行客观赋权相对减少了主观因素的影响;基于TOPSIS和GRA进行信息安全风险评估,综合被评价对象整体因素和内部因素,较有效地将多项信息安全风险评估指标综合成单一评分,便于对多个被评对象进行信息安全风险的择优与排序.

完全图高阶关系驱动的链接预测

图卷积网络(graph convolutional network,GCN)因其在处理图数据方面的独特优势而被广泛应用于推荐系统中,它通过利用图中节点之间的依赖关系传播节点属性信息,极大地提高了节点表示的准确度从而提升推荐性能.然而现有基于GCN的推荐方法仍因过平滑问题而难以进行更深层的建模,从而限制了用户与项目间高阶关系的表达.为此,提出了一种基于项目间关系的完全图高阶关系驱动的链接预测(link prediction driven by high-order relations in complete graph,LinkCG)方法.LinkCG通过用户-项目交互图与项目间隐式关联关系全局图组成的异构图预测用户到项目的链接,跳过了中间的用户节点直接利用完全图建模每个用户历史交互的项目间的局部隐式关联关系,获得项目间的高阶关系从而缓解数据稀疏性问题;此外,不同于基于节点嵌入的推荐方法,LinkCG通过赋予项目间的链接权重来表示项目间关系的紧密程度,并根据紧密程度进行链接预测,优化了模型的训练过程.在3个公开数据集上的实验结果表明,LinkCG作为只包含2个超参数的非深度学习模型,与一些先进的基于深度学习的基线方法相比提供了更好的性能.在社交关系数据上的应用进一步表明LinkCG能够从用户历史交互项目中获取足够丰富的用户偏好信息.
