Intelligent fault monitoring and diagnosis of tunnel fans using a hierarchical cascade forest

Tunnel fan is critical fire-fighting equipment, and its safe and stable operation is very important for the efficiency and safety of tunnel traffic. Existing studies commonly train the fault diagnosis methods with the goal of minimizing mean error which ignores the difference between classes in feature distribution. To solve the problem of inaccurate prediction caused by mean error evaluation, this paper presents a non-neural deep learning model, namely hierarchical cascade forest, which has three characteristics: (1) A hierarchical cascade structure is constructed, of which the output comes from each layer; (2) Each fault class is evaluated and recognized independently, the result of fault classes that are easy to distinguish is output earlier; (3) A confidence-based threshold estimate method is proposed in HCF and used to improve the training method to increase the reliability of HCF. Based on these, HCF improves the cascade forest structure and implements the proper matching of different depth of feature and fault patterns. The effect of HCF is verified through experiments based on the tunnel fans testing rig. Experimented results show that, compared to Deep Forest, the accuracy of HCF increases by 0.6% to 10.8%, and the training time of HCF is reduced 33.24%.
A Deep Learning-Based Cascade Automatic Classification System for Malignant Thyroid Nodule Recognition in Ultrasound Image

As the most common malignancy in the endocrine system, thyroid cancer is often determined based on ultrasound images by professional radiologists based on ultrasound images. In this study, a cascade automatic classification system (CACS) is proposed to accurately achieve automatic segmentation and classification of thyroid nodules, reducing over-reliance on experienced doctors in the diagnosis. Firstly, the Res-UNet is used to segment the region of interest (ROI) of thyroid nodules in ultrasound images. Then, to overcome the limitations of the small sample size of medical training data as well as category imbalance, the modified Conditional Variational Auto-Encoder (CVAE), learning the probability distribution of the ultrasound images, is trained to produce new medical ultrasound images for ROI data augmentation. Finally, we perform the classification task by a three-branch ensemble network combined with clinical diagnostic features of thyroid nodule such as the aspect ratio, internal and external echoes, and edges. The proposed CACS can identify benign and malignant thyroid nodules with an accuracy of 0.892 and an AUC of 0.887, according to testing on real patient data.

The Mediated Effects of Quality of Life, and Moderating Effects on Premenstrual Coping Methods in Relationship between Premenstrual Syndrome(PMS) and Attitudes Towards Menstruation

Objectives This study verifies the mediated effects of quality of life, and moderating effects on premenstrual coping methods, in respect of Premenstrual Syndrome and attitudes towards menstruation. Methods 376 adult women in their 20s and 30s in Busan and Gyeongsangbuk-do were tested to measure premenstrual syndrome and related variables, and analyzed using Hayes' (2013) PROCESS Model 5. This model includes both indirect and controlled direct effects, and the indirect effect on the relationship between the preceding variable and the outcome variable was verified by brush wrapping, and the controlled direct effect was verified the interaction significance of the preceding variable and the control variable. Results First, the indirect effects of quality of life were examined in relation to premenstrual syndrome and attitudes towards menstruation. Second, the negative effect of premenstrual syndrome on attitudes toward menstruation showed that adjusting energy and self-care methods had moderating effects among premenstrual coping methods. However, avoiding harm, awarensess and acceptance of premenstrual change, and communication methods did not show any moderating effect. Conclusions This means that premenstrual syndrome affects the attitude towards menstruation through the quality of life. Among the premenstrual coping methods, passive coping does not reduce the negative effect of premenstrual syndrome on attitudes toward menstruation, and it means that active coping methods can reduce the negative effect of premenstrual syndrome on attitudes toward menstruation. In particular, it means that it is more effective to respond more actively, such as exercise or relaxation training, to directly alleviate symptoms rather than simply being aware of premenstrual changes. Finally, this study discussed the significance and limitations of this study and recommendations for further study.
