In order to improve the dynamic performance during startup process of hydropower units, while considering efficient and stable speed increase effective suppression water pressure fluctuations mechanical vibrations, optimization algorithms must be used select optimal parameters for system. However, in current research, various multi-objective still have limitations terms target space coverage diversity maintenance parameter hydraulic turbines. To explore verify turbines, multiple strategies are proposed this study. Under condition constructing a fine-tuned nonlinear model control system, paper focuses on three key indicators: absolute integral deviation, snail shell fluctuation, relative value maximum axial thrust. Through comparative analysis particle swarm algorithm (MOPSO), variant (VMOPSO), sine cosine (MOSCA), biogeography (MOBBO), gravity search (MOGAS), improved (IMOPSO), obtained compared analyzed strategy, most suitable actual working conditions selected through comprehensive weighting method. The results show that, local solution problem caused by other algorithms, method significantly reduces vibrations ensuring improvement, achieving better performance. significant guiding significance smooth operation safety provide strong support making operational decisions.

Improving facial expression recognition for autism with IDenseNet‐RCAformer under occlusions

International Journal of Developmental Neuroscience, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 27, 2024

The term 'autism spectrum disorder' describes a neurodevelopmental illness typified by verbal and nonverbal interaction impairments, repetitive behaviour patterns poor social interaction. Understanding mental states from FEs is crucial for interpersonal But when there are occlusions like glasses, facial hair or self-occlusion, it becomes harder to identify expressions accurately. This research tackles the issue of identifying parts face occluded suggests an innovative technique tackle this difficulty. Creating strong framework expression recognition (FER) that better handles increases accuracy goal research. Therefore, we propose novel Improved DenseNet-based Residual Cross-Attention Transformer (IDenseNet-RCAformer) system partial occlusion FER problem in autism patients. framework's efficacy assessed using four datasets expressions, some preprocessing procedures conducted increase efficiency. After that, recognizing simple argmax function applied get forecasted landmark position heatmap. Then feature extraction phase, local global representation captured preprocessed images adopting Inception-ResNet-V2 approach, Transformer, respectively. Moreover, both features fused employing FusionNet method, thereby enhancing system's training speed precision. extracted, improved DenseNet mechanism efficiently recognize variety partially A number performance metrics determined analysed demonstrate proposed approach's effectiveness, where IDenseNet-RCAformer performs best with 98.95%. According experimental findings, significantly outperforms prior frameworks terms outcomes.
