Applied Sciences, Vol. 16, Pages 9338: Defect-Specific Physical-Prior-Guided Synthesis of Photovoltaic RGB Defect Images with Pixel-Level Annotations
5+ min ago (305+ words) Reliable visual inspection of photovoltaic modules is limited by the scarcity of diverse defect images and pixel-level annotations. This study proposes a defect-specific RGB image synthesis framework combining local feature disentanglement and physical-prior-guided modeling for shadow, debris, dust, and broken…...
Applied Sciences, Vol. 16, Pages 9339: Hybrid Grey Wolf Optimizers with Probabilistic Spiral Updating for Global Optimization
5+ min ago (427+ words) The Grey Wolf Optimizer (GWO) is a widely used meta-heuristic optimization algorithm; however, its standard linear encircling mechanism often leads to premature convergence to local optima in complex search spaces, and the equal weighting of its top three leaders limits…...
Applied Sciences, Vol. 16, Pages 9342: Receptive-Field-Aware Adaptive Fusion for Multiscale Insulator Defect Detection in Transmission-Line Images
25+ min ago (418+ words) Transmission-line inspection requires a single detector to localize complete insulator strings together with much smaller broken-shell and flashover-damaged regions. These targets differ in spatial extent and in their dependence on local detail and surrounding context, which complicates cross-scale feature fusion…...

The Department of Applied Mathematics, College of Science and Technology, Andhra University, began a five-day Faculty Development Programme (FDP) on “Emerging Applications of Linear Algebra and…...
Applied Sciences, Vol. 16, Pages 9333: Towards Unified Affective AI: A Cross-Modal Survey of Emotion Recognition, Generation, and Control
34+ min ago (539+ words) Emotion recognition and generation have become increasingly important research areas in artificial intelligence, underpinning applications in healthcare, education, customer service, and human–computer interaction. Human emotion is inherently multimodal, being conveyed through facial expressions, speech, and language, while modern affective…...
Applied Sciences, Vol. 16, Pages 9337: Deep Learning for Surface-Conditioned Structural Crack Recognition: Integrating CNN-Attention Models and Calibrated Confidence Estimation
45+ min ago (410+ words) Surface recognition can organize structural inspection imagery, but high classification accuracy does not establish crack detection or structural diagnosis. This study evaluates the supplied 49,124-image StructDamage collection, containing nine surface categories and 4586 masonry-focused images. A shared ResNet-18 encoder supports ten…...
Did you know that Your presentation and Your AI knowledge source can be the same file.

Build an insider-buying screener with Python and SEC Form 4 data
1+ hour, 7+ min ago (1355+ words) A director bought $101,760 of Tenax Therapeutics. Another bought $500,000 of Inhibrx Biosciences. Sorted by dollars, the second purchase comes first. Measured against the holding reported with each transaction, the increases were 2330.7% and 1.2%. Both numbers came back in the same API field....
