Background: Melanoma is a highly aggressive form of skin cancer, necessitating early and accurate detection for effective treatment. This study aims to develop novel classification system melanoma that integrates Convolutional Neural Networks (CNNs) feature extraction the Aquila Optimizer (AO) dimension reduction, improving both computational efficiency accuracy. Methods: The proposed method utilized CNNs extract features from images, while AO was employed reduce dimensionality, enhancing performance model. effectiveness this hybrid approach evaluated on three publicly available datasets: ISIC 2019, ISBI 2016, 2017. Results: For 2019 dataset, model achieved 97.46% sensitivity, 98.89% specificity, 98.42% accuracy, 97.91% precision, 97.68% F1-score, 99.12% AUC-ROC. On 2016 it reached 98.45% 98.24% 97.22% 97.84% 97.62% 98.97% 2017, results were 98.44% 98.86% 97.96% 98.12% 97.88% 99.03% outperforms existing advanced techniques, with 4.2% higher 6.2% improvement in 5.8% increase specificity. Additionally, reduced complexity by up 37.5%. Conclusions: deep learning-Aquila (DL-AO) framework offers efficient detection, making suitable deployment resource-constrained environments such as mobile edge computing platforms. integration DL metaheuristic optimization significantly enhances robustness, detection.

This paper examines land management technologies to enhance environmental monitoring more efficiently. The study highlights the interactions between human activities and systems with a data-driven approach. There are many pressures, such as pollution, degradation, habitat loss, negatively impacting soil health. methodology proposed improves status assessments in response evolving pressures by utilizing satellite imagery predictive modeling. integration of Sentinel-2 imagery, calculation various spectral indices (NDVI, NBR, NDMI, EVI, SAVI) at different time intervals, application Isolation Forest algorithm employed this determine specific area that is affected issue. chosen was favored due its superior performance handling high-dimensionality data, enhanced computational efficiency, provision interpretable results, insensitivity disparities class distribution. analyzes two separate cases scales. first involves wildfire identification achieving an overall accuracy 98%. second focuses on expansion areas pre-existing quarries 95%. NBR proved most effective delineating burned areas, whereas EVI generated remarkable results quarry case study. approach provides scalable tool for monitoring, supporting sustainable policies, strengthening ecosystem resilience.

The environmental impacts of mining activities in Southeast Nigeria pose significant challenges and threats to the local ecosystems communities. Research reveals that impact these had hitherto been poorly monitored or assessed due inefficient manual approach used. Now, there are currently gaps literature on potential advanced technologies for sustainable management vis-à-vis practices Nigeria. This research therefore seeks bridge this gap has adopted a review method synthesize existing knowledge determine prospects integration geospatial machine learning monitoring managing support improved decision-making. adhered PRISMA guidelines, which involved an initial evaluation 550 articles eventually resulted 64 relevant materials used study. findings indicate led severe land degradation, deforestation, water contamination, adversely affecting biodiversity livelihoods. study also revealed hold great monitoring, assessment, as whole call urgent policy considerations from stakeholders governments.
