New computational treatment of optical wave propagation in lossywaveguides

Jian-xin ZHU,Guan-jie WANG

《信息与电子工程前沿（英文）》 2015年第16卷第8期页码 646-653 doi: 10.1631/FITEE.1400406

摘要： In this paper, the optical wave propagation in lossy waveguides is described by the Helmholtz equation with the complex refractive-index, and the Chebyshev pseudospectral method is used to discretize the transverse operator of the equation. Meanwhile, an operator marching method, a one-way re-formulation based on the Dirichletto-Neumann (DtN) map, is improved to solve the equation. Numerical examples show that our treatment is more efficient.

An isogeometric numerical study of partially and fully implicit schemes for transient adjoint shape sensitivity

Zhen-Pei WANG, Zhifeng XIE, Leong Hien POH

《机械工程前沿（英文）》 2020年第15卷第2期页码 279-293 doi: 10.1007/s11465-019-0575-5

摘要： In structural design optimization involving transient responses, time integration scheme plays a crucial role in sensitivity analysis because it affects the accuracy and stability of transient analysis. In this work, the influence of time integration scheme is studied numerically for the adjoint shape sensitivity analysis of two benchmark transient heat conduction problems within the framework of isogeometric analysis. It is found that (i) the explicit approach ( = 0) and semi-implicit approach with <0.5 impose a strict stability condition of the transient analysis; (ii) the implicit approach ( =1) and semi-implicit approach with > 0.5 are generally preferred for their unconditional stability; and (iii) Crank–Nicolson type approach ( =0.5) may induce a large error for large time-step sizes due to the oscillatory solutions. The numerical results also show that the time-step size does not have to be chosen to satisfy the critical conditions for all of the eigen-frequencies. It is recommended to use for unconditional stability, such that the oscillation condition is much less critical than the Crank–Nicolson scheme, and the accuracy is higher than a fully implicit approach.

Trapezoidal Intuitionistic Fuzzy Aggregation Operator Based on Choquet Integral and Its Application to

Xi-hua Li,Xiao-hong Chen

《工程管理前沿（英文）》 2015年第2卷第3期页码 266-276 doi: 10.15302/J-FEM-2015048

摘要： The Choquet integral can serve as a useful tool to aggregate interacting criteria in an uncertain environment. In this paper, a trapezoidal intuitionistic fuzzy aggregation operator based on the Choquet integral is proposed for multi-criteria decision-making problems. The decision information takes the form of trapezoidal intuitionistic fuzzy numbers and both the importance and the interaction information among decision-making criteria are considered. On the basis of the introduction of trapezoidal intuitionistic fuzzy numbers, its operational laws and expected value are defined. A trapezoidal intuitionistic fuzzy aggregation operator based on the Choquet integral is then defined and some of its properties are investigated. A new multi-criteria decision-making method based on a trapezoidal intuitionistic fuzzy Choquet integral operator is proposed. Finally, an illustrative example is used to show the feasibility and availability of the proposed method.

一般四元数函数梯度的定义、特性及在信号处理领域的应用

Meng-di Jiang, Yi Li, Wei Liu,w.liu@sheffield.ac.uk

《信息与电子工程前沿（英文）》 2016年第17卷第2期页码 83-95 doi: 10.1631/FITEE.1500334

摘要：目的：随着四元数在信号处理各个领域越来越广泛的应用，基于四元数的信号处理理论也获得了快速发展。然而，制约其进一步应用的一个瓶颈就是对一般四元数函数的梯度的定义及特性还缺乏清晰并有说服力的描述。本文就试图对这一问题进行探索。创新点：在信号处理中，虽然很多优化函数的值都是实数，但在进行优化时，尤其是在非线性信号处理中，经常会遇到对取值为四元数的四元数函数求梯度。不同于以往只适用于实数值四元数函数梯度的定义，本文第一次就一般四元数函数的梯度给出了一个自洽的定义，并对其特性进行了详细的研究和描述。基于以上研究，本文对四元数值的最小均方(LMS)自适应算法，以及一个有代表性的非线性自适应算法进行了推导，并以矢量传感器阵列波束形成为例进行了计算机模拟。

Iterative HOEO fusion strategy: a promising tool for enhancing bearing fault feature

《机械工程前沿（英文）》 2023年第18卷第1期 doi: 10.1007/s11465-022-0725-z

摘要： As parameter independent yet simple techniques, the energy operator (EO) and its variants have received considerable attention in the field of bearing fault feature detection. However, the performances of these improved EO techniques are subjected to the limited number of EOs, and they cannot reflect the non-linearity of the machinery dynamic systems and affect the noise reduction. As a result, the fault-related transients strengthened by these improved EO techniques are still subject to contamination of strong noises. To address these issues, this paper presents a novel EO fusion strategy for enhancing the bearing fault feature nonlinearly and effectively. Specifically, the proposed strategy is conducted through the following three steps. First, a multi-dimensional information matrix (MDIM) is constructed by performing the higher order energy operator (HOEO) on the analysis signal iteratively. MDIM is regarded as the fusion source of the proposed strategy with the properties of improving the signal-to-interference ratio and suppressing the noise in the low-frequency region. Second, an enhanced manifold learning algorithm is performed on the normalized MDIM to extract the intrinsic manifolds correlated with the fault-related impulses. Third, the intrinsic manifolds are weighted to recover the fault-related transients. Simulation studies and experimental verifications confirm that the proposed strategy is more effective for enhancing the bearing fault feature than the existing methods, including HOEOs, the weighting HOEO fusion, the fast Kurtogram, and the empirical mode decomposition.

Reliability analysis of urban gas transmission and distribution system based on FMEA and correlation operator

Su LI,Weiguo ZHOU

《能源前沿（英文）》 2014年第8卷第4期页码 443-448 doi: 10.1007/s11708-014-0336-4

摘要： In order to improve the safety management of urban gas transmission and distribution system, failure mode and effects analysis (FMEA) was used to construct the reliability analysis system of the pipeline network. To solve the problem of subjectivity and uncertainty of the multi-expert decision making, the correlation operator was introduced into the calculation of the risk priority number (RPN). Using FMEA along with weight analysis and expert investigation approach, the FMEA evaluation table was given, including five failure modes, risk priority numbers, failure causes and effects, as well as corrective actions. The results show that correlation operator can directly process the linguistic terms and quantify the priority of the risks.

摘要： The aim of this paper is to analyze unbalanced radial distribution systems (UBRDS) with the distribution static compensator (D-STATCOM). The main objectives of this paper are D-STATCOM allocation in UBRDS with an objective of providing reactive power support to enhance voltage profile and reduce line losses of the distribution network, determination of optimal D-STATCOM rating subjected to minimization of total cost, and impact of D-STATCOM placement on improving power factor and savings in cost of energy loss. The analysis is conducted on a large industrial load model with light, medium and high loading scenarios. Further, the impact of load growth is also considered for better planning of the power distribution system. The results are obtained on standard 25-bus UBRDS to check the feasibility of the proposed methodology.

一种基于变异算子与淘汰重组机制的改进GWO及其应用 Article

Xiao-qing ZHANG, Zheng-feng MING

《信息与电子工程前沿（英文）》 2017年第18卷第11期页码 1705-1719 doi: 10.1631/FITEE.1601555

摘要：标准苍狼优化算法（grey wolf optimizer, GWO）因其简单易用的特性受到广泛关注。由于存在搜索结构不完善、易陷入局部最优等问题，其应用范围受到了限制。本文提出了一种基于变异算子和淘汰重组机制的苍狼优化算法（eliminating-reconstructing GWO, MR-GWO）。对GWO的分析表明，GWO仅以三个领导层苍狼为核心进行搜索，且仅通过调整参数a来平衡算法的探索和开发性能，意味着苍狼群在一定程度上失去了多样性。因此，本文对优秀的搜索狼引入变异算子，对性能较差的搜索狼采用淘汰重组机制，不仅有效地扩展了算法的随机搜索面，同时加快了算法收敛速度。为了验证改进后算法的有效性，通过13个标准连续函数全局优化实验及RBF（radial basis function）网络逼近试验将MR-GWO算法与其它算法进行了比较，试验结果表明MR-GWO算法具有较强的竞争力。

Interactive DE for solving combined security environmental economic dispatch considering FACTS technology

Belkacem MAHDAD, K. SRAIRI, B. TAREK

《能源前沿（英文）》 2013年第7卷第4期页码 429-447 doi: 10.1007/s11708-013-0270-x

摘要： This paper presents an efficient interactive differential evolution (IDE) to solve the multi-objective security environmental/economic dispatch (SEED) problem considering multi shunt flexible AC transmission system (FACTS) devices. Two sub problems are proposed.The first one is related to the active power planning to minimize the combined total fuel cost and emissions, while the second is a reactive power planning (RPP) using multi shunt FACTS device based static VAR compensator (SVC) installed at specified buses to make fine corrections to the voltage deviation, voltage phase profiles and reactive power violation. The migration operation inspired from biogeography-based optimization (BBO) algorithm is newly introduced in the proposed approach, thereby effectively exploring and exploiting promising regions in a space search by creating dynamically new efficient partitions. This new mechanism based migration between individuals from different subsystems makes the initial partitions to react more by changing experiences. To validate the robustness of the proposed approach, the proposed algorithm is tested on the Algerian 59-bus electrical network and on a large system, 40 generating units considering valve-point loading effect. Comparison of the results with recent global optimization methods show the superiority of the proposed IDE approach and confirm its potential for solving practical optimal power flow in terms of solution quality and convergence characteristics.

《信息与电子工程前沿（英文）》 2021年第22卷第12期页码 1551-1684 doi: 10.1631/FITEE.2000658

摘要：低功耗有损网络路由协议（RPL）由因特网工程任务组设计，主要适用于通信条件复杂、环境恶劣的低功耗有损网络。为进一步提高低功耗有损网络性能，本文提出一种基于三角模算子的情景感知RPL新算法（CAR-TMO）。首先设计了一种新的情景感知复合路由度量（CA-RM）；CA-RM可综合评估候选父节点的剩余能量指数、缓存占用率、以及该候选父节点到根节点之间路径所需的期望传输数（ETX）、时延和跳数。CA-RM以递归方式评估了候选父节点及其偏好父节点的剩余能量指数和缓存占用率，以降低上游父节点对偏好父节点选择的影响。CA-RM综合使用路径上各链路ETX和时延的和值、均值和均方差值以进一步提高网络性能。其次，设计了上述各路由度量的隶属度函数。然后，基于三角模算子和各路由度量的隶属度函数构造综合隶属度函数和情景感知目标函数（CA-OF）。此外，提出新的计算节点秩值和偏好父节点选择机制。最后，理论分析和仿真结果均表明，CAR-TMO在分组投递成功率、能效等方面均优于RPL及其相关改进算法。

《信息与电子工程前沿（英文）》 2017年第18卷第10期页码 1525-1533 doi: 10.1631/FITEE.1601364

摘要：旅行商问题（traveling salesman problem, TSP）是经典的NP（non-deterministic polynomial）难问题，在实际工程中有许多应用。而果蝇优化算法作为一种用于求解TSP问题的新群智能算法，具有易于理解、实现简单等优点。然而，该算法收敛速度慢、易陷入局部最优，从而导致寻优精度不高。为了有效求解TSP问题，本文提出了三种改进方法，以优化果蝇算法在TSP求解中的应用。一是，更加注重果蝇觅食行为中的视觉搜索能力，从而增强果蝇算法的收敛能力；二是，在果蝇优化算法中融入了淘汰机制以增加种群多样性；三是，提出了逆序操作算子和乘法操作算子，并将这两种基本操作算子运用到果蝇算法求解TSP问题上。本文对TSPLIB中的10个算例进行仿真实验，并与其它算法的实验结果进行对比，结果证明该算法不仅收敛速度快，而且寻优精度高。
