The manufacturing industry tries to innovate always cater customer-oriented products. digitization of is revolutionizing the future this industry. Industrial Internet Things (IIoT) bringing down labor cost, reducing machine downtime, and overall increasing production speed. A new technological trend like Machine Learning (ML) a subset Artificial Intelligence (AI) that uses computer algorithms based on available data can improve or decide further, automatically, experience, without need for prior programming commands. ML daily processes identifying bottlenecks, developing products, controlling quality, providing security industry, using AI robotics in place humans. On one hand, technologies ML, AI, IIoT, materials, photonics, rapid prototyping are driving sector adopting version Industry 4.0, other European Commission (EC) has defined roadmap until 2050 more, achieving sustainable goal carbon-neutrality complete digitalization with resilience across continent. However, it challenging match planned actual roadmaps technology-based There uncertainties about how will be shaped by EU changing political, environmental social world environment. Recognizing these difficulties, current article consults literature topic determine factors characterize countries. relevant information sectors first been collected from various sources Eurostat data, EC policy documents, company's annual reports, research reviews, journal articles, Days event, etc. Then were analyzed gain insight into context Commission's outlined policies. Variable different presented member states scenario analysis was used understanding possible future. It concluded does not lie adapting environment but creating companies themselves - revolution must met revolution. Their early experiences path dependency seen as stubbornness, which may act formidable barriers building capabilities. Therefore, step-wise integrate resources create process, structure, personnel motivation, fits broader coming decades.

The transition to sustainable electricity generation depends heavily on renewable energy sources, particularly wind power. Making precise forecasts, which calls for clever predictive controllers, is a crucial aspect of maximizing the efficiency turbines. This study presents DeepVELOX, new methodology. With this method, sophisticated machine learning methods are smoothly incorporated into power systems. Increased Velocity (IN-VELOX) turbine framework combines Gradient Boosting Regressor (GBR) with Grey Wolf Optimization (GWO) algorithm. Predictive capabilities entering age thanks integration. research its structure, and results. In particular, considerable performance DeepVELOX. MAPE 0.0002 an RMSPE 0.0974, it gets outstanding Key Performance Indicator (KPI) criteria Accuracy, F1-Score, R2-Score, Precision, Recall, value 1, further emphasize performance. result process MSE 0.0352. significant reduction in forecast disparities made possible by system’s remarkable accuracy. Along improving accuracy, integration algorithms, including GBR, GWO algorithm, operations, offer dynamic capture.

Although floating offshore wind technology is gaining interest due to its potential, the platform part makes highest proportion of total cost. As a result, an appropriate selection necessary reduce This research identifies best system-based on-site properties (wind resource, water depth, distance shore, port, sea state, and shipping traffic) via Analytical Hierarchy Process. Experts answered questionnaire with numerical values create pairwise comparison for criteria alternatives. Results show that experts do not prefer Tension Leg Platform complexity in installation. Meanwhile, most likely high-traffic density sites Spar system. However, Semi-submersible systems are proposed as alternative light traffic sites. A validated AHP-based model simplify selection.

Wind energy technology is progressing at an accelerated pace due to the growing global demand for renewable energy, particularly horizontal axis wind turbines (HAWTs). Ducted (DWTs) have emerged as a promising enhancement traditional turbines, demonstrating substantial improvements in efficiency and power output. This study presents comprehensive evaluation of four distinct designs DWTs, with focus on critical factors including efficiency, cost-effectiveness, durability, environmental sustainability. Among analyzed, Diffuser configuration emerges most advantageous terms cost, delivering more economically than Nozzle-Diffuser design. The durability analysis underscores design’s superior longevity, indicated by index 0.9, reflecting its robust construction low maintenance demands. Additionally, design shown be highly environmentally sustainable, achieving Environmental Impact Score 0.91, highlighting minimal carbon footprint high recyclability. concludes that offers balanced effective solution, combining cost considerations while maintaining competitive levels.
