Electric Power Systems Research, 2026
This paper delves into determining optimal zone-II settings for distance relays (DS) in coordination with numerical relays equipped with new proposed flexible time-voltage-current characteristics (FTVCC). A comprehensive comparative analysis is conducted, considering the existing standard and fully adjustable characteristic configurations of numerical relays proposed in the past literature on optimal protection coordination problem (OPCP). The study encompasses a thorough investigation of the applicability of the proposed FTVCC utilizing 9 bus, 14 bus, and IEEE 39 bus systems, with results compared across different relay characteristics. The results are achieved using nonlinear programming methodology with OPTI global optimization toolbox. The percentage reduction FTVCC achieved in the objective function is 41.09%, 37.72%, and 77.05% for the 9 bus, 14 bus, and IEEE 39 bus systems, respectively, when compared with the existing characteristics. The test systems are designed in DIGSILENT power factory, and the electromagnetic transient (EMT) simulations are extracted and fed to the FPGA-based FTVCCs through MATLAB Simulink interface in the experimental framework. This ensures that the performance and functionality of the proposed FTVCC are tested and verified under FPGA-validated conditions driven by different fault scenarios, serving as a preliminary semi-hardware verification step prior to full-scale field implementation for future works.

In this work, machine learning (ML) models have been developed to predict the feature responses in additive manufacturing to guide the process operation to achieve higher prediction accuracy. Artificial neural network models have been trained with the help of nature-inspired metaheuristic algorithms. This work also demonstrates the power of nature-inspired algorithms for learning the complex non-linearity present inside the data set. Importantly, the proposed models serve as a foundation for Digital Twin enabled AM process optimization under uncertainty, enhancing real-time monitoring and predictive analytics in additive manufacturing systems. Several prediction models were established among the laser power, scanning speed and track width, track depth, track height, and contact angle on the formation of a single track. The performance of various models in terms of their prediction accuracy, adaptability and relevance were further evaluated by comparing each of the models outcome. The experimental data has been collected from the literature. The result shows that the iFANN gives a better performance for predicting the track width, depth, height, and contact angle. The metaheuristic algorithm-guided neural network models perform extremely well for predicting the track height and contact angle compared to the traditional regression model. The iFANN model achieved minimized RMSE prediction value with only 30 generations, which traditional backpropagation model fails to achieve the same accuracy even with higher number of generations.

Global municipal solid waste generation is projected to exceed 3.8 billion tonnes annually by 2050. This makes the need for smart, inclusive, and scalable waste valorization systems more urgent than ever. This review critically explores the shift from conventional waste management to intelligent, technology‐driven solutions aligned with circular economy goals. Key findings highlight the transformative role of digital tools in waste classification, forecasting, and real‐time monitoring. Long Short‐Term Memory models achieved up to 94% accuracy in biogas prediction, while XGBoost demonstrated 98.5% accuracy in solid waste generation forecasting. Deep learning systems have reached classification accuracies of 83.11% across 28 recyclable categories and mean average precision scores up to 63% in complex waste detection. Despite promising advances, challenges such as data quality, regulatory hurdles, and system interoperability persist. This article contributes both a conceptual and practical blueprint for stakeholders, positioning smart waste valorization as a strategic opportunity to drive innovation.

International Journal on Interactive Design and Manufacturing, 2026
Fused Deposition Modeling (FDM) is a widely adopted additive manufacturing process in which surface roughness (SR) critically influences the performance and appearance of printed components. This study presents an Artificial Neural Network (ANN) model to predict and optimize SR based on three key process parameters: extrusion temperature, layer height, and printing speed. A full factorial design of 64 experiments was conducted using PLA material, and the resulting data were used to train a 3-10-1 ANN architecture in MATLAB R2021a. The model was trained using the Levenberg–Marquardt algorithm with a 70:15:15 split for training, validation, and testing. The ANN achieved a high correlation coefficient (R² >0.99) and a maximum prediction error of 1.23%, confirming its robustness and accuracy. Analysis showed that layer height had the greatest impact on SR due to the staircase effect, while extrusion temperature and printing speed had secondary effects. Optimal surface roughness was achieved at an extrusion temperature of 210 °C, layer height of 0.1 mm, and printing speed of 40 mm/s, consistently improving surface quality across horizontal, vertical, and inclined orientations. These settings minimize surface roughness by balancing thermal adhesion, layer resolution, and deposition accuracy across varied geometries. The developed ANN model offers a reliable, data-driven tool for process optimization in FDM, enabling improved print quality and reduced trial-and-error in industrial applications. Graphical abstract
Comparative study of FSW and TIG welding of AA3003 aluminium flange joints under varying tool geometries and rotational speeds
Ibrahim Sabry, Noah E. El-Zathry, Rasheedat M. Mahamood, Stephen Akinlabi, Wai Lok Woo
Welding in the World, 2026
Flange joints are widely used in pipelines, heat exchangers, and pressure-retaining aluminium structures, yet their behaviour under friction stir welding (FSW) remains insufficiently explored in the literature. This study addresses this gap by evaluating the combined effects of tool geometry and rotational speed on the microstructural and mechanical performance of FSW AA3003 flange joints, with Tungsten Inert Gas (TIG) welding used as a benchmark. The conical-pin tool produced superior weld quality, generating refined stir-zone grains (7.26 µm), higher hardness (46 HV₀.₂), and the highest tensile strength (185 MPa) owing to enhanced material flow and dynamic recrystallisation. The cylindrical pin yielded slightly lower properties (44 HV₀.₂, 165 MPa), while TIG welds exhibited coarse dendritic structures and reduced strength. Hydrostatic testing further demonstrated the sealing advantage of FSW, with conical-pin welds remaining leak-tight up to 32 bar, compared with failure at 23–25 bar in TIG joints. These results establish optimised FSW, particularly with conical-pin geometry, as a high-integrity, energy-efficient, and sustainable joining method for aluminium flange assemblies.

Journal of Field Robotics, 2026
An in‐depth understanding of the risks related to robotic systems is crucial to guarantee safety throughout all stages of robot design and operations. This required a thorough risk assessment following international standards. This study presents a systematic review of previous research on safety considerations in the design of robotic systems, concentrating exclusively on peer‐reviewed articles. A search method was developed to collect relevant articles, using keywords such as safety, fault, risk evaluation, safety evaluation, risk assessment, and ergonomics, among others. The keyword “robot” was utilized to bias the search results, which helped to narrow down collected articles to papers directly related to robotics. The risk assessment process includes recognizing machine shortcomings, recognizing threats, evaluating risk, and articulating a standardized computerized risk strategy. Mathematical analysis plays a crucial role in assessing the technical and social behavior of robots in different applications. Generally, injury associated with robots arises from errors during risk assessment. The Risk Ranking Number (HRN) is employed to quantify the degree of safety, incorporating factors like the possibility of occurrence and magnitude of potential hazard. In robot design, the main attention should be on minimizing/eradicating physical hazards and optimizing control mechanisms. Algorithms like force limitation and obstacle avoidance can minimize injury risk, especially during robot–human interactions. The review underscores the critical importance of establishing comprehensive risk assessment frameworks and utilizing safety models, algorithms, and functions as crucial tools to safeguard the integrity and security of robotic systems.

International Journal of Advanced Manufacturing Technology, 2025
Ultrasonic Vibration–Assisted Friction Stir Welding (UVaFSW) represents a next-generation solid-state joining technology designed to overcome the limitations of conventional friction stir welding by integrating ultrasonic energy to promote refined microstructures and superior joint integrity. This study presents a systematic optimisation and metallurgical investigation of UVaFSW applied to aerospace-grade AA2060-T8E30 Al–Li alloy, linking process design, microstructural evolution, and mechanical performance through Response Surface Methodology (RSM). A Central Composite Design was employed to model the effects of tool rotational speed (TRS), traverse speed (TTS), axial force (AF), tilt angle (TA), and ultrasonic vibration amplitude (Amplitude, µm) on ultimate tensile strength (UTS), elongation (EL), and hardness (HV). The optimised parameters (TRS = 1200 rpm, TTS = 2 mm s⁻¹, AF = 6 kN, TA = 2°, Amplitude = 15 μm) yielded UTS = 449.8 MPa, EL = 12.9%, and HV = 129.1, achieving ~ 90% joint efficiency with R² > 94%. Metallurgical characterisation revealed that an intermediate-amplitude (15 μm) deformation induced intense dynamic recrystallisation, refined grains to ≈ 4.6 μm, and homogenised the S′–Al₂CuMg and Al₆(Mn, Fe) precipitates, simultaneously enhancing strength and ductility. This work establishes a quantitative link between ultrasonic amplitude, microstructural evolution, and mechanical optimisation in Al–Li alloy UVaFSW, demonstrating its potential to produce defect-free, high-efficiency joints for sustainable aerospace manufacturing.
Comparative evaluation of conventional friction stir welding and ultrasonic vibration-assisted friction stir welding techniques

Journal of Advanced Joining Processes, 2025
• Ultrasonic vibration-assisted FSW (UVaFSW) improved joint strength and ductility of AA2060-T8, with UTS increasing by up to 31.8 % and elongation reaching 11 %. • UVaFSW refined grain structure and enhanced precipitate uniformity, leading to improved microstructural homogeneity and weld quality. • UVaFSW eliminated surface defects and produced defect-free joints under high-speed conditions (4 mm/s, 6 kN), which were prone to flaws in FSW. Enhancing joint strength in aluminium alloys remains a critical challenge for industrial applications. Friction stir welding (FSW) is a solid-state welding process that offers superior weld quality compared to fusion methods. However, further advancements are needed, particularly for high-performance alloys like third-generation Al-Li. To address this, ultrasonic vibration-assisted FSW (UVaFSW) has been explored as a potential enhancement. This study compares the mechanical and microstructural properties of AA2060-T8-E30 joints produced by FSW and UVaFSW. Key process parameters, including tool traverse speed and ultrasonic vibration amplitude (7.5 µm and 22.5 µm), were varied to assess their influence on weld quality. Mechanical performance was evaluated through tensile testing and Vickers microhardness, while microstructural characteristics were examined using optical microscopy and SEM. The results demonstrated that UVaFSW significantly improved material flow, reduced asymmetry in the thermo-mechanically affected zone (TMAZ), and refined the grain structure. Consequently, the ultimate tensile strength increased by 16.6 % and 31.8 % at 7.5 µm and 22.5 µm amplitudes, respectively, and elongation reached 11 %, nearly three times that of FSW. Furthermore, UVaFSW produced finer grains and more uniform precipitate distribution. Therefore, UVaFSW emerges as a promising technique for enhancing weld quality in advanced Al-Li alloys for demanding engineering applications.

This study investigated the potential of biochar produced via torrefaction of rice straw as a sustainable alternative to coal and coke in iron and steel production. The effects of process parameters, temperature (200–300 °C), residence time (20–60 min), and heating rate (10–30 °C/min) on torrefaction yield were evaluated. Following optimization, the biochar was characterized through ultimate, proximate, SEM, BET, EDS, and TG analyses, and its properties were compared to those of coal. The results indicated that the solid, Liquid, and syngas yields ranged from 44.67–96.43, 1.50–22.39, and 2.07–36.79%, respectively. The optimized process parameters achieved a solid yield of approximately 64% at an optimal temperature of 270 °C. The moisture, ash, volatile, and fixed contents of the biochar ranged from 7.43–8.80, 5.76–6.87, 21.75–28.26, and 56.83–63.82%, respectively. Among the optimized samples, O3 exhibited superior combustion performance, with a fixed carbon content of 63.82%, and morphological properties comparable to bituminous coal. The HHV (19.88 MJ/kg) of the optimized biochar falls within the upper range of lignite and approaches the lower range of bituminous coal. The optimized biochar showed a significantly higher BET surface area (58.845–59.572 m2/g) than lignite and anthracite (0.187–1.498 m2/g). Its BJH-specific surface area (47.423–48.194 m2/g) also far exceeds that of coal (0.178–1.985 m2/g), indicating superior adsorption capacity. Additionally, the total pore volume of the biochar (0.1366–0.1407 cm3/g) and average pore diameter (4.457–4.765 nm) surpass those of coal, supporting enhanced mass transfer and surface interactions.
