In deep learning, the choice of activation function plays a vital role in enhancing model performance. We propose AHerfReLU, a novel activation function that combines the rectified linear unit (ReLU) function with the error function (erf), complemented by a regularization term 1/(1 + x2), ensuring smooth gradients even for negative inputs. The function is zero centered, bounded below, and nonmonotonic, offering significant advantages over traditional activation functions like ReLU. We compare AHerfReLU with 10 adaptive activation functions and state-of-the-art activation functions, including ReLU, Swish, and Mish. Experimental results show that replacing ReLU with AHerfReLU leads to 3.18% improvement in Top-1 accuracy on the LeNet network for the CIFAR100 dataset, 0.63% improvement on CIFAR10%, and 1.3% improvement in mean average precision (mAP) on the SSD300 model in the Pascal VOC dataset. Our results demonstrate that AHerfReLU enhances model performance, offering improved accuracy, loss reduction, and convergence stability. The function outperforms existing activation functions, providing a promising alternative for deep learning tasks.

在深度学习中,激活函数的选择对提高模型性能起着至关重要的作用。我们提出的 AHerfReLU 是一种新型激活函数,它将整流线性单元(ReLU)函数与误差函数(erf)相结合,并辅以正则化项 1/(1+x2),即使在负输入的情况下也能确保平滑的梯度。与 ReLU 等传统激活函数相比,该函数具有零中心、下限值和非单调性等显著优势。我们将 AHerfReLU 与 10 个自适应激活函数和最先进的激活函数(包括 ReLU、Swish 和 Mish)进行了比较。实验结果表明,用 AHerfReLU 替代 ReLU 后,LeNet 网络在 CIFAR100 数据集上的 Top-1 精度提高了 3.18%,在 CIFAR10% 数据集上提高了 0.63%,在 Pascal VOC 数据集上的 SSD300 模型的平均精度 (mAP) 提高了 1.3%。我们的研究结果表明,AHerfReLU 增强了模型性能,提高了精度、损失减少率和收敛稳定性。该函数的性能优于现有的激活函数,为深度学习任务提供了一种有前途的替代方法。

This paper designs an optimal control strategy for the auto-berthing control (ABC) problem of underactuated surface vessels. The purpose is to achieve accurate berthing of USVs in complex environments. In the traditional ABC problem of surface vessels, the underactuated characteristics of USVs complicate the control design. This underactuated phenomenon is manifested in the lack of lateral driving force on the boat, which restricts its motion to a specific direction. In order to solve the problem of the lack of lateral driving force of USVs, this paper first uses diffeomorphism transformation to transform the original nonholonomic constraint system into a chain structure. Through this transformation, the problem of the state of the vessel being restricted during motion is avoided. On this basis, this paper further describes the optimal control problem of the USV on the horizontal plane based on the kinematic and dynamic models of the USV. In order to solve the optimal control problem, this paper adopts the Gaussian pseudospectral method (GPM). By discretizing the continuous optimal control problem into a nonlinear programming problem, the computational complexity is effectively reduced and the solution efficiency is improved. The optimal navigation trajectory of the USV system and the corresponding optimal control input are then obtained. In order to verify the feasibility and effectiveness of the proposed control strategy, numerical simulation is carried out. The simulation results show that the optimal control strategy can achieve stable and accurate berthing of USVs.

针对欠驱动水面船舶的自动靠泊控制问题,设计了一种最优控制策略。目的是实现无人潜航器在复杂环境下的准确靠泊。在传统的水面舰艇ABC问题中,无人潜航器的欠驱动特性使控制设计复杂化。这种欠驱动现象表现在船上缺乏横向驱动力,这限制了它的运动到一个特定的方向。为了解决无人潜航器横向动力不足的问题,本文首先利用微分同构变换将原非完整约束系统转化为链式结构。通过这种变换,避免了船舶在运动过程中状态受限的问题。在此基础上,基于USV的运动学模型和动力学模型,进一步阐述了USV在水平面上的最优控制问题。为了解决最优控制问题,本文采用高斯伪谱法(GPM)。通过将连续最优控制问题离散化为非线性规划问题,有效地降低了计算量,提高了求解效率。得到了无人潜航器系统的最优导航轨迹和相应的最优控制输入。为了验证所提控制策略的可行性和有效性,进行了数值仿真。仿真结果表明,该最优控制策略能够实现无人水面艇稳定、准确靠泊。

Tracking athletes in high-speed outdoor sports like alpine skiing causes substantial difficulties because of ever-changing movements, environmental variability, and the limitations of traditional tracking technologies, such as intrusive sensors and single-view camera setups. This study proposes a hybrid approach for tracking alpine skiing activities by combining YOLO-v8 with an evolutionary version of the chimp optimization algorithm (CHOA-EVOL) for optimizing hyperparameters. The primary goal of this research is to enhance the CHOA to optimally adjust the hyperparameters of YOLO-v8, consequently addressing the drawbacks of outdoor sports tracking technology. This hybrid model integrates data from unmanned aerial vehicles (UAVs) and terrestrial cameras to better understand athletes’ rapid rotating motion. The suggested approach is extensively tested and validated using advanced algorithms with the UAV123 dataset and a recently developed alpine skiing dataset (ASD). The results have shown that our proposed approach can achieve high precision and robustness.

The existence of clearance in the joint causes positional deviation and reduces the accuracy of robotics, in which nonlinear factors such as friction and lubrication inside the joint seriously affect its dynamic behaviors. On the other hand, the effectiveness of control algorithms is largely dependent on the dynamic complexity of the robotics, while its complexity analysis is an important prerequisite for achieving high-performance control. In this paper, we provide a method for analyzing the dynamic complexity of a planar manipulator with clearance and lubrication in joints based on a nonlinearity measure. The influences of joint parameters such as friction coefficient, lubricant viscosity, and gap radius are quantified on the dynamic complexity of the kinetics, which can identify the collision state of the joints effectively in the robot’s motion. First, a dynamical model of a planar manipulator is established by integrating the contact-separation model and the force model at the joint, and a method for calculating the dynamic complexity based on the nonlinearity measure is proposed. Second, the effects of different joint parameters on the dynamic behaviors of the robotic system are analyzed, and the relationships between the lubricant viscosity, gap radius, and the dynamic complexity under different friction coefficients are established to analyze the impacts of the joint parameters on the dynamic complexities. The results show that the dynamic complexity of the robotic system can be decreased significantly by using the small gap radius and high viscosity of the lubricant, which can help to realize the better control performance. Especially, this method is more sensitive to state changes such as the collision state of the joint relative to the sample entropy method.

关节间隙的存在导致机器人的位置偏差,降低了机器人的精度,其中关节内部的摩擦和润滑等非线性因素严重影响了机器人的动力学行为。另一方面,控制算法的有效性在很大程度上取决于机器人的动态复杂性,而其复杂性分析是实现高性能控制的重要前提。本文提出了一种基于非线性测度分析具有间隙和关节润滑的平面机械臂动态复杂度的方法。量化了摩擦系数、润滑剂粘度、间隙半径等关节参数对动力学动态复杂度的影响,能够有效识别机器人运动中关节的碰撞状态。首先,将平面机械臂的接触分离模型与关节处的力模型相结合,建立了平面机械臂的动力学模型,并提出了基于非线性测度的动态复杂度计算方法。其次,分析了不同关节参数对机器人系统动力学行为的影响,建立了不同摩擦系数下润滑油粘度、间隙半径与动态复杂度的关系,分析了关节参数对动态复杂度的影响;结果表明,采用小间隙半径和高粘度的润滑油可以显著降低机器人系统的动态复杂性,有助于实现更好的控制性能。特别是,相对于样本熵法,该方法对关节的碰撞状态等状态变化更为敏感。

Inspired by the genetic evolution mechanism of DNA, a hybrid DNA Gray Wolf Optimizer (hDNA-GWO) is proposed to develop an accurate kinetic model. This algorithm incorporates innovative DNA encoding, selection, crossover, and mutation operators inspired by genetic processes. We adopt the roulette-wheel method to select individuals with greater environmental adaptability from the current population to form the next population. The crossover operation involves swapping gene segments between paired chromosomes to create new individuals and maintain the population diversity. The mutation operator can maintain the diversity of the population, avoid the phenomenon of “premature” convergence, and effectively improve the local search capability. The performance of hDNA-GWO is investigated on typical benchmark functions compared to GWO, PSO, GWO-PSO, and GWO-GA. In addition, the superior search capabilities of our model are validated by kinetic parameter estimation using experimental data from supercritical water oxidation processes. The results indicate that the hDNA-GWO can overcome premature convergence and obtain higher-quality global optimal solutions.

Using the matching data of the UN COMTRADE, China Customs, and China Industrial Enterprise database from 2000 to 2013, we explore the relationship between product density and the export technological complexity at the enterprise level. We find product density at the firm level has a significant positive effect on the export technological complexity of Chinese manufacturing enterprises. The result remains still robust after adopting instrumental variable method, replacing explanatory and explained variables and substituting more detailed data for the proxy variables. Both specialized agglomeration and diversified agglomeration have significant positive effects on the export technological complexity. The results of moderating effect test indicate that specialized industry agglomeration has significantly reinforced the abovementioned effects as a moderator. However, diversified agglomeration significantly inhibits the technological upgrading effect. Heterogeneity tests show that product density is more conducive to the upgrading of the export technological complexity of enterprises in the eastern region, and so are to the foreign-funded, capital-intensive, and technology-intensive enterprises.

利用2000 - 2013年UN COMTRADE、中国海关和中国工业企业数据库的匹配数据,在企业层面探讨了产品密度与出口技术复杂性之间的关系。研究发现,企业层面的产品密度对中国制造业出口技术复杂性具有显著的正向影响。采用工具变量法,替换解释变量和被解释变量,用更详细的数据替换代理变量后,结果仍然是稳健的。专业化集聚和多元化集聚对出口技术复杂性均有显著的正向影响。调节效应检验结果表明,专业化产业集聚显著强化了上述调节效应。然而,多元化集聚显著抑制了技术升级效应。异质性检验表明,产品密度更有利于东部地区企业出口技术复杂程度的提升,外资、资本密集型和技术密集型企业出口技术复杂程度的提升也是如此。

To suppress the frequency oscillation phenomenon that occurs in the parallel control system of multiple virtual synchronous generators (multi-VSG) during load mutation, this paper proposes a multi-VSG parallel control strategy based on sliding mode linear active disturbance rejection (SM-LADRC). Initially, mathematical modeling of the multi-VSG parallel control system is conducted to analyze the mechanism by which load mutation affect frequency. Subsequently, based on the rotor motion equation of the VSG, linear active disturbance rejection control (LADRC) is applied to the angular frequency, and an extended state observer (ESO) is constructed to estimate and compensate for the system’s frequency state and load mutation in real time, thereby enhancing the system’s disturbance rejection capability. Concurrently, an integral sliding mode linear state error feedback (SM-LSEF) control law is formulated to rapidly adjust the frequency error control quantity, eliminating the reaching phase and accelerating the system’s response speed. Moreover, the integral sliding mode, by introducing an integral term, continuously approximates the switching function, making the sliding mode surface smoother, which effectively suppresses sliding mode chattering and improves the system’s robustness. Finally, simulation comparisons validate the correctness and effectiveness of the proposed control strategy, providing a theoretical and simulation experimental basis for engineering applications.

为了抑制多台虚拟同步发电机(multi-VSG)并联控制系统在负载突变时出现的频率振荡现象,本文提出了一种基于滑模线性有源干扰抑制(SM-LADRC)的多台虚拟同步发电机并联控制策略。首先,对多 VSG 并联控制系统进行数学建模,分析负载突变对频率的影响机制。随后,根据变速发电机的转子运动方程,对角频率采用线性主动干扰抑制控制(LADRC),并构建扩展状态观测器(ESO)来实时估计和补偿系统的频率状态和负载突变,从而增强系统的干扰抑制能力。同时,制定了积分滑动模式线性状态误差反馈(SM-LSEF)控制法则,以快速调整频率误差控制量,消除到达阶段,加快系统响应速度。此外,积分滑动模态通过引入积分项,不断逼近开关函数,使滑动模态面更加平滑,从而有效抑制了滑动模态振颤,提高了系统的鲁棒性。最后,仿真对比验证了所提控制策略的正确性和有效性,为工程应用提供了理论和仿真实验依据。

Moreover, the integral sliding mode, by introducing an integral term, continuously approximates the switching function, making the sliding mode surface smoother, which effectively suppresses sliding mode chattering and improves the system’s robustness. Finally, simulation comparisons validate the correctness and effectiveness of the proposed control strategy, providing a theoretical and simulation experimental basis for engineering applications.</p>\u0000 </div>","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2025 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/cplx/9646736","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss the relationship between environmental sustainability and system complexity. This is motivated by the fact that solutions to environmental challenges often create additional complexity in the overall socioeconomic system, at local to global levels. This increase in complexity might hamper the ultimate achievement of sustainability. This theme is over utmost importance but is overlooked in studies of environmental sustainability, environmental and climate policy, and sustainability transitions. It merits serious attention as this can provide a general basis and clarification of related topics that are currently studied in isolation—think of energy rebound, carbon leakage, green paradox (fossil fuel market responses to climate policy), circular economy, and environmental problem shifting. The relationship between complexity and sustainability is examined from thermodynamic and systemic perspectives, resulting in identifying a set of mechanisms of complexity increase and clarifying how this potentially creates barriers to meeting sustainability goals. While this issue is pertinent to all economies and countries, it is of high relevance to developing countries as their economies are likely to undergo considerable complexity increases in the near future due to further development. The question is then whether countries will be able to steer their development in a sustainable direction while simultaneously limiting a more roundabout nature of their production structure. We contend that this may require “complexity policy” and outline ideas in this regard. An important role can be played by cap-and-trade, but this will work mainly for carbon emission and not for other environmental pressures. Ultimately, a policy mix could guide different subsystem complexities in terms of environmental pressures and welfare impacts—resulting in optimizing system complexity for sustainability.

我们讨论了环境可持续性与系统复杂性之间的关系。这是因为环境挑战的解决方案往往会在地方和全球层面上给整个社会经济系统带来额外的复杂性。这种复杂性的增加可能会阻碍可持续性的最终实现。这个主题非常重要,但在环境可持续性、环境和气候政策以及可持续性转型的研究中却被忽视了。它值得认真关注,因为它可以为目前孤立研究的相关主题提供总体基础和澄清-想想能源反弹,碳泄漏,绿色悖论(化石燃料市场对气候政策的反应),循环经济和环境问题转移。从热力学和系统的角度考察了复杂性和可持续性之间的关系,从而确定了一套复杂性增加的机制,并阐明了这种机制如何可能对实现可持续性目标造成障碍。虽然这个问题与所有经济体和国家有关,但它与发展中国家高度相关,因为它们的经济在不久的将来可能由于进一步发展而变得相当复杂。那么问题就在于,各国是否能够在控制其生产结构更加迂回的同时,将其发展导向可持续的方向。我们认为,这可能需要“复杂性政策”,并概述了这方面的想法。限额与交易可以发挥重要作用,但这主要是针对碳排放,而不是针对其他环境压力。最终,政策组合可以在环境压力和福利影响方面指导不同子系统的复杂性,从而优化系统复杂性以实现可持续性。

In the context of rapid development of social networks, users gather together through social network platforms (SNPs) to form social circles, which become the main carriers for users to disseminate public opinion information and emotions, and it is easy to form the phenomenon of network public opinion polarization in social circles. To prevent the polarization of network public opinions in social circles, the application of blockchain technology to SNPs can provide a credible database for the traceability of public opinions and avoid the spread of false information in social circles. Based on blockchain traceability, this paper establishes a three-party evolutionary game model consisting of government, SNPs, and social circle managers (SCMs). Through model solving and numerical simulation, the influencing factors of each party’s strategy are analyzed. The findings suggest: (1) Although the rising cost of building blockchain platforms may undermine the government’s incentive to regulate, the government will still prioritise support for their construction if they can significantly enhance social welfare. (2) The government could boost SNPs’ willingness to adopt blockchain technology through subsidy measures, but increased privacy risks could undermine this willingness. (3) Blockchain technology realizes the traceability of public opinion and improves the rational guidance tendency of SCMs. Therefore, in order to promote and strengthen the collaborative governance of network public opinion in social circles, SNPs should enhance the use of blockchain technology, while the government should give full play to its regulatory and supervisory roles. This study introduces blockchain technology for public opinion traceability; explores a collaborative network public opinion governance system based on strict regulation by the government, introduction of blockchain technology by SNPs, and rational guidance by SCMs; expands the related research on network public opinion governance; and provides a new idea for the study of network public opinion governance of social circles based on blockchain traceability.

在社交网络快速发展的背景下,用户通过社交网络平台(snp)聚集在一起形成社交圈,成为用户传播舆情信息和情绪的主要载体,极易形成社交圈内网络舆情两极分化的现象。为防止网络舆情在社交圈的两极分化,将区块链技术应用于snp,可以为舆情溯源提供可信的数据库,避免虚假信息在社交圈的传播。基于区块链可追溯性,本文建立了由政府、snp和社交圈管理者(scm)组成的三方进化博弈模型。通过模型求解和数值模拟,分析了各方策略的影响因素。研究结果表明:(1)尽管建设区块链平台的成本上升可能会削弱政府的监管动机,但如果区块链平台能够显著提高社会福利,政府仍将优先支持其建设。(2)政府可以通过补贴措施提高snp采用区块链技术的意愿,但隐私风险的增加会破坏这种意愿。(3)区块链技术实现了舆论的可追溯性,提高了scm的理性引导倾向。因此,为了促进和加强社交圈网络舆情的协同治理,snp应加强区块链技术的使用,而政府应充分发挥其监管和监督作用。本研究引入区块链技术进行舆情溯源;探索政府严格监管、snp引入区块链技术、scm合理引导的协同网络舆情治理体系;拓展网络舆情治理的相关研究;为基于区块链溯源的社交圈网络舆情治理研究提供了一种新的思路。

Correct detection of plant diseases is critical for enhancing crop yield and quality. Conventional methods, such as visual inspection and microscopic analysis, are typically labor-intensive, subjective, and vulnerable to human error, making them infeasible for extensive monitoring. In this study, we propose a novel technique to detect tomato leaf diseases effectively and efficiently through a pipeline of four stages. First, image enhancement techniques deal with problems of illumination and noise to recover the visual details as clearly and accurately as possible. Subsequently, regions of interest (ROIs), containing possible symptoms of a disease, are accurately captured. The ROIs are then fed into K-means clustering, which can separate the leaf sections based on health and disease, allowing the diagnosis of multiple diseases. After that, a hybrid feature extraction approach taking advantage of three methods is proposed. A discrete wavelet transform (DWT) extracts hidden and abstract textures in the diseased zones by breaking down the pixel values of the images to various frequency ranges. Through spatial relation analysis of pixels, the gray level co-occurrence matrix (GLCM) is extremely valuable in delivering texture patterns in correlation with specific ailments. Principal component analysis (PCA) is a technique for dimensionality reduction, feature selection, and redundancy elimination. We collected 9014 samples from publicly available repositories; this dataset allows us to have a diverse and representative collection of tomato leaf images. The study addresses four main diseases: curl virus, bacterial spot, late blight, and Septoria spot. To rigorously evaluate the model, the dataset is split into 70%, 10%, and 20% as training, validation, and testing subsets, respectively. The proposed technique was able to achieve a fantastic accuracy of 99.97%, higher than current approaches. The high precision achieved emphasizes the promising implications of incorporating DWT, PCA, GLCM, and ANN techniques in an automated system for plant diseases, offering a powerful solution for farmers in managing crop health efficiently.
