The rapid digitalization of modern power infrastructures, combined with the integration of renewable energy (RE) and battery energy storage systems (ESS), has become pivotal to achieving a sustainable and resilient energy future. However, this convergence introduces critical cybersecurity vulnerabilities that can compromise system reliability, operational continuity, and data integrity. This paper provides a comprehensive review of cybersecurity risks specific to RE–ESS ecosystems, analyzing potential attack vectors, system-level impacts, and their implications for grid stability. It synthesizes recent advances in defense mechanisms, including anomaly detection through artificial intelligence, blockchain-secured data transactions, zero-trust network frameworks, and cryptographic protection of control systems. Beyond technical countermeasures, the study emphasizes the need for a unified cybersecurity governance framework that integrates regulatory standards, operational protocols, and resilience metrics. This review identifies persistent gaps in real-time threat detection, cross-domain data protection, and policy harmonization across energy markets. To address these, adaptive AI-driven monitoring, risk-based vulnerability assessments, and compliance alignment with international standards are proposed. By linking cybersecurity assurance with the functional reliability of energy storage infrastructures, this work contributes to the development of secure, efficient, and sustainable digital energy systems. The findings offer actionable insights for engineers, operators, and policymakers seeking to enhance the resilience of energy storage systems in the evolving smart grid landscape.

现代电力基础设施的快速数字化，加上可再生能源（RE）和电池储能系统（ESS）的整合，已成为实现可持续和有弹性的能源未来的关键。然而，这种融合引入了关键的网络安全漏洞，可能会损害系统可靠性、操作连续性和数据完整性。本文全面回顾了RE-ESS生态系统特有的网络安全风险，分析了潜在的攻击向量、系统级影响及其对电网稳定性的影响。它综合了防御机制的最新进展，包括通过人工智能进行异常检测、区块链安全数据交易、零信任网络框架和控制系统的加密保护。除了技术对策之外，该研究还强调需要一个统一的网络安全治理框架，该框架将监管标准、操作协议和弹性指标集成在一起。本综述确定了在实时威胁检测、跨域数据保护和能源市场政策协调方面存在的持续差距。为了解决这些问题，提出了自适应人工智能驱动的监测、基于风险的脆弱性评估以及与国际标准的一致性。通过将网络安全保障与储能基础设施的功能可靠性联系起来，这项工作有助于开发安全、高效和可持续的数字能源系统。研究结果为工程师、运营商和政策制定者提供了可行的见解，帮助他们在不断发展的智能电网环境中提高储能系统的弹性。

This review integrates bibliometric methods with a quantitative–qualitative analysis to evaluate various types of grouting materials for prefabricated grouted sleeve connections. Key findings reveal that conventional cement-based grouts (CGM) achieve 28-day compressive strengths of 80–95 MPa with initial flowability of 300–350 mm through controlled water-to-binder ratios and the use of superplasticizers. Fiber reinforcement increases strength by up to 30 % but reduces flowability by 5–20 %, depending on the dosage. Ultra-high performance concrete (UHPC)-based grouts deliver superior performance (105–160 MPa compressive strength) and enable 25–40 % shorter anchorage lengths compared with conventional materials, albeit at higher cost and with reduced injectability. Chemical admixtures in CGM provide quantifiable benefits: polycarboxylate superplasticizers maintain flowability without compromising strength; silicone-based defoamers can increase 28-day strength by 33–43 % while reducing total porosity by 37 %, and calcium formate accelerators enable strengths of 50 MPa at 1 day. The review also identifies gaps: the understanding of degradation mechanisms under coupled environmental actions is limited because most studies isolate single factors; research on self-healing grouts for sleeves remains sparse and lacks systematic comparisons; and data on the influence of the binder-to-sand ratio on bond performance are insufficient. Future work should prioritize multiscale characterization under coupled conditions, the development of degradation models, and the advancement of sustainable grout formulations incorporating industrial by-products. This review provides quantitative benchmarks for material selection and identifies technical challenges that must be addressed to improve the reliability of prefabricated construction.

本文将文献计量学方法与定量定性分析相结合，对预制灌浆套筒连接的各种灌浆材料进行了评价。关键研究结果表明，通过控制水胶比和使用高效减水剂，常规水泥基注浆（CGM）的28天抗压强度为80-95 MPa，初始流动性为300-350 mm。纤维增强可使强度提高30%，但根据用量的不同，可使流动性降低5 - 20%。基于超高性能混凝土（UHPC）的灌浆具有卓越的性能（105-160 MPa抗压强度），与传统材料相比，锚固长度缩短了25 - 40%，尽管成本更高，可注入性降低。CGM中的化学外加剂提供了可量化的好处：聚羧酸高效减水剂保持流动性而不影响强度；硅基消泡剂可将28天强度提高33 - 43%，同时将总孔隙率降低37%，甲酸钙促进剂可使1天强度达到50 MPa。审查还指出了差距：对耦合环境作用下的退化机制的理解有限，因为大多数研究孤立单一因素；套筒自愈灌浆的研究仍然很少，缺乏系统的比较；而胶砂比对粘结性能影响的数据还不够。未来的工作应优先考虑耦合条件下的多尺度表征、降解模型的开发以及包含工业副产品的可持续注浆配方的进步。本综述为材料选择提供了定量基准，并确定了必须解决的技术挑战，以提高预制结构的可靠性。

In large-aperture parabolic trough solar power plants, improving the efficiency of heat collection elements remains a critical research challenge. This study proposes an integrated system consisting of a novel vacuum absorber tube combined with a flat secondary reflector, configured within a three-stage heating structure to form a single-loop parabolic trough solar collector system. The system includes three sequentially arranged absorber sections with diameters decreasing from 90 mm to 80 mm and finally to 70 mm, coupled with an 8 m-wide aperture concentrator. Under direct normal irradiance levels ranging from 400 to 1000 W/m², the system achieves an optical efficiency of 79.3 % and a thermal efficiency between 62.9 % and 72.8 %. The total loop length is 1314.5 m, representing a reduction of 71.5 m (5.2 %) compared to a conventional system using an optimal 90 mm absorber tube. Furthermore, the optical and thermal efficiencies are improved by 3.1 % and 4.0 %, respectively. Additionally, the system enables the heat transfer fluid to reach an outlet temperature exceeding 560 °C, significantly enhancing its applicability in high-efficiency power cycles. These results demonstrate the potential of the proposed multi-stage variable-diameter design to simultaneously enhance optical performance, thermal output, and economic feasibility in next-generation concentrated solar power applications.

在大孔径抛物面槽式太阳能电站中，提高集热元件的效率仍然是一个重要的研究挑战。本研究提出了一种集成系统，该系统由一种新型真空吸收管和一个平面二次反射器组成，配置在一个三级加热结构中，形成一个单回路抛物线槽太阳能集热器系统。该系统包括三个顺序排列的吸收器部分，直径从90mm减小到80mm，最后减小到70mm，再加上一个8 m宽孔径的集中器。在400 ~ 1000 W/m²的直接辐照度下，该系统的光学效率为79.3%，热效率为62.9% ~ 72.8%。总回路长度为1314.5 m，与使用最佳90 mm吸收管的传统系统相比，减少了71.5 m（5.2%）。此外，光效率和热效率分别提高了3.1%和4.0%。此外，该系统使传热流体的出口温度达到560°C以上，大大提高了其在高效电源循环中的适用性。这些结果证明了所提出的多级变直径设计的潜力，可以同时提高下一代聚光太阳能应用的光学性能、热输出和经济可行性。

Building Information Modelling (BIM) offers considerable potential for the construction industry, particularly in terms of transparency, increased efficiency and integrated data management throughout the entire life cycle of buildings. However, technical and organizational barriers exist, which limit the widespread adoption of BIM. This study therefore employed two large-scale, online surveys to analyze the technical and organizational aspects of BIM implementation in lighting design. The results show that, in addition to technical barriers, successful BIM implementation hinges on knowledge, acceptance, and organizational learning ability. Training, internal processes and a supportive corporate culture are crucial for the effective use of new workflows. Fragmented planning processes and asynchronous participation reinforce technical limitations. To fully realize the potential of BIM, an integrated approach combining technological innovations with organizational learning and collaborative structures is essential. Key solutions include modular, interoperable BIM systems, open interfaces, and standardized data structures.

建筑信息模型（BIM）为建筑行业提供了巨大的潜力，特别是在透明度、提高效率和在建筑整个生命周期内集成数据管理方面。然而，存在技术和组织障碍，这限制了BIM的广泛采用。因此，本研究采用了两个大规模的在线调查来分析BIM在照明设计中实施的技术和组织方面。结果表明，除了技术障碍外，BIM的成功实施还取决于知识、接受度和组织学习能力。培训、内部流程和支持性的企业文化对于有效使用新的工作流程至关重要。分散的规划过程和异步参与强化了技术限制。为了充分发挥BIM的潜力，将技术创新与组织学习和协作结构相结合的综合方法是必不可少的。关键解决方案包括模块化、可互操作的BIM系统、开放接口和标准化数据结构。

Lightning strikes pose a growing threat to wind turbines, particularly due to climate change and technological advancements. This study focuses on the 9 MW Lamma Wind Power Plant (WPP) in Hong Kong, analyzing the effects of standard and non-standard lightning waveforms on its components based on the strike's location. There are four suggested ways to lower the risk: choosing the right metal oxide surge arrester (MOSA), building a high voltage filter (HVF), using both at the same time, and using both an externally gapped line arrester (EGLA) and a non-gapped line arrester (NGLA). Modeling with MATLAB/SIMULINK revealed that a lightning strike near the inverter increased peak voltage by 12.3 %, with the tail time parameter rising from 50 to 300 microseconds, leading to a 36.6 % increase in peak voltage at the impact site. The concurrent use of MOSA and HVF significantly reduced lightning risk by 95 % compared to HVF alone and 96.3 % compared to MOSA alone. Additionally, four EGLA models were developed, with the composite air gap variant reducing overvoltage by approximately 57.2 % compared to NGLA alone. These mitigation strategies not only enhance the safety of wind power plants but also lower maintenance and replacement costs for expensive components.

雷击对风力涡轮机构成越来越大的威胁，特别是由于气候变化和技术进步。本研究以香港9 MW南丫岛风力发电厂（WPP）为研究对象，根据雷击位置分析标准和非标准雷击波形对其组件的影响。有四种方法可以降低风险：选择合适的金属氧化物避雷器（MOSA），构建高压滤波器（HVF），同时使用这两种避雷器，以及同时使用外部间隙线避雷器（EGLA）和非间隙线避雷器（NGLA）。利用MATLAB/SIMULINK建模表明，在逆变器附近的雷击使峰值电压增加12.3%，尾时间参数从50微秒增加到300微秒，导致冲击点峰值电压增加36.6%。同时使用MOSA和HVF与单独使用HVF相比可显著降低95%的雷电风险，与单独使用MOSA相比可降低96.3%的雷电风险。此外，开发了四种EGLA模型，与单独的NGLA相比，复合气隙变体可以降低约57.2%的过电压。这些缓解策略不仅提高了风力发电厂的安全性，而且降低了昂贵部件的维护和更换成本。

Accurate localization is essential for Unmanned Aerial Vehicles (UAVs) in mission-critical applications such as military operations, search and rescue, and environmental monitoring. While Global Navigation Satellite Systems (GNSS) provide reliable positioning in open environments, GNSS-denied conditions remain challenging, such as in obstructed or hostile environments. Various localization strategies have been developed using visual and/or non-visual sensors such as LiDAR, barometers, Inertial Measurement Units (IMU), and cameras, with recent advances in machine learning. However, there is a lack of comparative studies that analyze the trade-offs between learning-based and conventional estimation approaches in such conditions. This study bridges that gap by comparing two fundamentally different methods: a Terrain Contour Matching algorithm-Extended Kalman Filter framework (TERCOM-EKF), and Visual-Inertial Sensor Fusion with Random Forest Regression (ViSensorRF), a machine learning approach based on Random Forest Regression (RFR). Both methods are evaluated in a GNSS-denied simulation environment using PX4, Robot Operating System (ROS) 2, Gazebo, and QGroundControl over a digital elevation model of the Taif region in Saudi Arabia. Results demonstrate that ViSensorRF achieves superior localization accuracy, with a root mean square error (RMSE) ranging between approximately 1 to 5 m across multiple trajectories, but requires significantly higher execution time of 1.92 s. In contrast, TERCOM-EKF offers faster computation of 0.04 s, making it suitable for real-time deployment in resource-constrained UAV systems. These findings highlight a trade-off between localization precision and computational efficiency, offering valuable insights for UAV deployment in GNSS-denied environments.

在军事行动、搜救和环境监测等关键任务应用中，精确定位对无人机（uav）至关重要。虽然全球导航卫星系统（GNSS）在开放环境中提供可靠的定位，但GNSS拒绝的条件仍然具有挑战性，例如在受阻或敌对环境中。利用视觉和/或非视觉传感器，如激光雷达、气压计、惯性测量单元（IMU）和相机，以及机器学习的最新进展，开发了各种定位策略。然而，在这种情况下，缺乏分析基于学习和传统估计方法之间权衡的比较研究。本研究通过比较两种根本不同的方法来弥补这一差距：地形轮廓匹配算法-扩展卡尔曼滤波框架（TERCOM-EKF）和视觉惯性传感器融合随机森林回归（ViSensorRF），一种基于随机森林回归（RFR）的机器学习方法。在gnss拒绝的仿真环境中，使用PX4、机器人操作系统（ROS） 2、Gazebo和QGroundControl对沙特阿拉伯塔伊夫地区的数字高程模型对两种方法进行了评估。结果表明，ViSensorRF实现了卓越的定位精度，在多个轨迹上的均方根误差（RMSE）在大约1到5 m之间，但需要显着提高的1.92 s的执行时间。相比之下，TERCOM-EKF提供了0.04秒的更快计算，使其适合在资源受限的无人机系统中实时部署。这些发现强调了定位精度和计算效率之间的权衡，为在gnss拒绝环境中部署无人机提供了有价值的见解。

Process fluids (MWFs) play a crucial role in machining operations by providing lubrication, cooling, and chip removal. Their quality directly impacts production efficiency and the service life of equipment. This study aimed to comprehensively assess the contamination of MWFs by microparticles and microorganisms in a turning center and to experimentally evaluate the effectiveness of advanced nanofiber filtration and ozonation in their removal. Five types of nanofiber filtration materials were tested using high-resolution microscopic and microbiological methods, including confocal microscopy, SEM/EDS, culture-based analysis, and quantitative PCR. The dominant contaminants were identified as iron, aluminum, and oxidation product particles ranging from 5 to 50 µm in size. The most effective filtration material was the Berry (Fiberweb, Synergex pure) nanofiber filter, achieving a removal efficiency of 69.3 %. Microbiological analysis revealed the presence of potentially pathogenic strains, including Pseudomonas aeruginosa, and demonstrated that a 30- min ozonation reduced the microbial load to 0–8 CFU/mL without significantly altering the pH. However, qPCR analysis detected residual bacterial DNA, indicating the presence of viable but non-culturable (VBNC) cells or free DNA fragments. These findings confirm that combining nanofiltration and ozonation offers an effective, chemical-free strategy to improve the hygiene and stability of MWFs. However, conventional microbiological methods should be complemented by molecular tools for accurate contamination monitoring.

加工流体（MWFs）在加工操作中起着至关重要的作用，提供润滑，冷却和切屑去除。它们的质量直接影响到生产效率和设备的使用寿命。本研究旨在综合评价微颗粒和微生物在旋转中心对MWFs的污染，并通过实验评估高级纳米纤维过滤和臭氧化去除MWFs的效果。采用高分辨率显微镜和微生物学方法，包括共聚焦显微镜、SEM/EDS、培养分析和定量PCR，对五种纳米纤维过滤材料进行了测试。主要污染物被确定为铁，铝和氧化产物颗粒范围从5到50µm的大小。最有效的过滤材料是Berry （Fiberweb， synerggex纯）纳米纤维过滤器，去除率达到69.3%。微生物学分析显示存在潜在的致病菌株，包括铜绿假单胞菌，并表明30分钟的臭氧化将微生物负荷降低到0-8 CFU/mL，而不会显著改变ph。然而，qPCR分析检测到残留的细菌DNA，表明存在活但不可培养（VBNC）细胞或游离DNA片段。这些发现证实，纳滤和臭氧氧化相结合提供了一种有效的、无化学物质的策略来改善MWFs的卫生和稳定性。然而，传统的微生物学方法应该与分子工具相辅相成，以实现准确的污染监测。

To develop high-performance hybrid perovskite solar cells, it seems necessary to identify the most suitable charge transport materials and perovskite absorber characteristics through a meticulous analysis of various device parameters, including layer thickness, doping concentration, and defect densities. In this work, the photovoltaic performance of triple cation mixed halide FAMACsPb(IBr)₃-based solar cells are investigated using one-dimensional Solar Cell Capacitance Simulator (SCAPS 1D) platform. Firstly, a study of various electron transport materials (ETMs) is carried out to understand their influence on the device’s performance. Once the ETM is chosen and their properties are identified, the optimization of the hole transport material (HTM) is carried out by varying its thickness and the doping concentration. Furthermore, the thickness and the defect density of the perovskite absorber were tuned to further optimize the performance of the designed solar cells. The optimized device exhibited a power conversion efficiency (PCE) of 26.16 %, with an open circuit voltage (V_oc), short-circuit current density (J_sc), and fill factor (FF) of 1.16 V, 26.28 mA.cm^-2, and 85.20 %, respectively. The findings of this study are expected to be a helpful reference for the future implementation of a cost-effective and efficient triple cation perovskite solar cell.

为了开发高性能的混合钙钛矿太阳能电池，似乎有必要通过对各种器件参数（包括层厚度、掺杂浓度和缺陷密度）的细致分析，确定最合适的电荷传输材料和钙钛矿吸收剂特性。本文利用一维太阳能电池电容模拟器（SCAPS 1D）平台研究了三阳离子混合卤化FAMACsPb(IBr)3基太阳能电池的光伏性能。首先，研究了各种电子传输材料（etm），以了解它们对器件性能的影响。一旦选择了ETM并确定了其性质，就可以通过改变其厚度和掺杂浓度来优化空穴输运材料。此外，还对钙钛矿吸收剂的厚度和缺陷密度进行了调整，以进一步优化所设计的太阳能电池的性能。优化后的器件功率转换效率（PCE）为26.16%，开路电压（Voc）、短路电流密度（Jsc）和填充因子（FF）分别为1.16 V、26.28 mA.cm-2和85.20%。本研究结果有望为未来实现经济高效的三阳离子钙钛矿太阳能电池提供有益的参考。

This study conducts a PRISMA-guided systematic review of Microbially Induced Calcite Precipitation (MICP) and Enzyme-Induced Calcite Precipitation (EICP) for improving the mechanical and hydraulic performance of clayey soils. The review synthesizes 37 peer-reviewed studies published between 2020 and 2025, evaluating relationships among microbial activity, chemical parameters, injection techniques, and soil mineralogy. Findings indicate that MICP generally yields higher unconfined compressive strength and lower permeability than EICP due to more efficient bacterial nucleation and calcite bonding. Controlled injection and electro-osmotic delivery enhance calcium carbonate uniformity, while extended curing promotes crystal densification and strength development. The addition of nano-SiO₂ and hybrid lime–MICP systems further refines microstructure and increases durability. Microstructural analyses using SEM, EDS, and XRD confirm rhombohedral calcite formation bridging clay particles, linking microscopic bonding with macroscopic strength gains. Key influencing factors include urea–Ca²⁺ balance, curing duration, and clay mineralogy. Identified limitations involve non-uniform precipitation, bacterial inactivity, and salinity inhibition, which can be mitigated through staged feeding, optimized ionic strength, and adaptive field protocols. Integrating sustainability assessment through Multi-Criteria Decision Analysis (MCDA) provides a framework for balancing performance, environmental impact, and cost efficiency. Overall, this review establishes mineralogy-aware and process-controlled bio-cementation as a scalable, sustainable alternative to traditional soil stabilization for fine-grained and low-permeability soils.

本研究以prisma为指导，系统综述了微生物诱导方解石降水（MICP）和酶诱导方解石降水（EICP）对改善粘性土力学和水力性能的作用。该综述综合了2020年至2025年间发表的37项同行评议研究，评估了微生物活动、化学参数、注射技术和土壤矿物学之间的关系。研究结果表明，由于更有效的细菌成核和方解石结合，MICP通常比EICP具有更高的无侧限抗压强度和更低的渗透率。控制注入和电渗透输送增强碳酸钙均匀性，延长固化时间促进晶体致密化和强度发展。纳米二氧化硅和混合石灰- micp系统的加入进一步细化了微观结构，提高了耐久性。通过SEM、EDS和XRD的微观结构分析，证实方解石形成的方解石是菱形的，桥接粘土颗粒，将微观结合与宏观强度增加联系起来。关键影响因素包括脲钙+平衡、固化时间和粘土矿物。确定的限制包括不均匀沉淀、细菌不活性和盐度抑制，可以通过分阶段进料、优化离子强度和自适应现场协议来缓解。通过多准则决策分析（MCDA）整合可持续性评估为平衡绩效、环境影响和成本效率提供了一个框架。总的来说，这篇综述建立了矿物学感知和过程控制的生物胶结作为一种可扩展的，可持续的替代传统土壤稳定的细粒和低渗透土壤。
