As a necessary protective equipment for workers to enter and exit the construction environment, safety helmets are of great significance to ensure the safe operation of workers. However, there are still some workers who lack safety awareness and do not wear safety helmets from time to time, and there are great safety hazards. This paper is based on the target detection algorithm of YOLOv4, focusing on the real construction site, and real-time detection of workers' helmet wearing in complex scenes. In order to solve the common phenomenon that only one type of helmet is detected, the helmet that is standing on the table or held in the hand is also recognized as a worker wearing a helmet. This article adds a human body model based on the helmet training. Training makes the detected helmet and the human body have a one-to-one correspondence. Experimental results show that the model achieves 93% accuracy on 9986 hard hat data sets. At the same time, the model has been deployed to the actual construction site to meet the daily detection of workers' hard hats, which verifies the effectiveness of the algorithm.
安全帽作为工人进出施工环境的必要防护装备,对保证工人的安全作业具有重要意义。但是,仍有一些工人缺乏安全意识,不经常戴安全帽,存在很大的安全隐患。本文以YOLOv4的目标检测算法为基础,着眼于真实施工现场,对复杂场景下工人头盔佩戴情况进行实时检测。为了解决只检测到一种头盔的普遍现象,将站在桌子上或拿在手里的头盔也识别为戴头盔的工人。本文增加了一个基于头盔训练的人体模型。训练使检测到的头盔与人体有一对一的对应关系。实验结果表明,该模型在9986个安全帽数据集上的准确率达到93%。同时,将模型部署到实际施工现场,满足工人安全帽的日常检测,验证了算法的有效性。

Deep learning is the current advanced solution for remote sensing segmentation. Massive high-quality training datasets are the basic inputs to deep learning networks for solving the segmentation problems. Most of the existing remotely sensed image datasets have low segmentation accuracy due to their coarse spatial resolution and the susceptibility to image noise. Image augmentation is a technical means of effectively solving deep learning trainings in small and/or low-quality training datasets, which has continuously accompanied the development of deep learning and machine vision. Many augmentation techniques and methods have been proposed to enrich and augment the training datasets and to improve the generalization ability of neural networks. Common image augmentation methods are based mainly on image transformations, such as photometric changes, flips, rotations, dithering and blurring. In this paper, the segmentation task of multispectral remote sensing data is validated by augmentation methods. The segmentation accuracy was found to be 96.10%, which is higher than that (92.36%) of the corresponding un-augmented data.
深度学习是当前遥感分割的先进解决方案。海量高质量的训练数据集是深度学习网络解决分割问题的基础输入。现有的遥感图像数据集由于空间分辨率较低,易受图像噪声的影响,分割精度较低。图像增强是一种有效解决小质量和/或低质量训练数据集上深度学习训练的技术手段,一直伴随着深度学习和机器视觉的发展。为了丰富和增强训练数据集,提高神经网络的泛化能力,人们提出了许多增强技术和方法。常用的图像增强方法主要基于图像变换,如光度变化、翻转、旋转、抖动和模糊。本文采用增强方法对多光谱遥感数据的分割任务进行了验证。结果表明,该算法的分割准确率为96.10%,高于未增强数据的分割准确率(92.36%)。

Emergency load shedding (ELS) is an essential measure to prevent power system accidents from expanding. Economy and security need to be optimized comprehensively for ELS. In this paper, an ELS optimization model is established, which takes the minimum load shedding amount as the objective function and the transient angle security, transient voltage deviation acceptability, transient frequency deviation acceptability, maximum controllable load as constraints. The social learning-based particle swarm optimization (SL-PSO) algorithm is proposed to solve the ELS optimization problem, which adopts adaptive parameters. The portable and open-source power system dynamic simulation toolkit (STEPS) is used for numerical simulation to check the feasibility of the solution. Finally, the efficiency of the solution is improved by parallel computing. The proposed model and algorithm are validated with the IEEE 39 bus test system.

Intrinsically disordered proteins (IDPs) possess flexible 3-D structures, which make them play an important role in a variety of biological functions. We develop a method to predict intrinsically disordered proteins based on feature selection and convolutional neural networks (CNN). The combination of structural, physicochemical and evolutionary properties is used to describe the differences between disordered and ordered regions. Especially, to highlight the correlation between the target residue and adjacent residues, multiple windows are selected to preprocess the selected properties. After that, these calculated properties are combined into the feature matrix to predict IDPs through the constructed CNN. Our method is training as well as testing based on the DisProt database. The simulation results show that the proposed method can predict intrinsically disordered proteins effectively, and the performance is competitive in comparison with IsUnstruct and ESpritz.

Massive small files access is the main challenge for the Hadoop Distributed File System. To solve these problems, we present a new Algorithm of archive file, A Faster Read and Less Storage Algorithm for Small Files on Hadoop. A new logical file name is used to identify the file which generated by the pair in the name node. Our experiments show that the algorithm is around 76.6% faster than original HDFS in the time of file storing, and around 31.9.6% faster than original HDFS in the time of file reading, around 73.9% less than original HDFS in the memory consumption of namenode.

Risk Analysis Based on Quantum Theory 基于量子理论的风险分析
Pub Date : 2021-08-01 DOI: 10.1109/ICCEAI52939.2021.00038
Yan Zhimei, Pan Ping
The risk is uncertain. It is impossible to determine the influence of a risk by default risk, but only to cognize the influence degree of its existence. In an open behavior system, according to the quantum theory, the risk is reflected in the wave function of the behavioral system, and at risk, the dynamic evolution of the system is determined by the environmental Hamiltonian in system Hamiltonian. When the environment is perfectly correlated to the eigenvalue of the behavior subject, it does not affect its evolution, and the risk is controllable. Otherwise, the risk will harm the evolution of the behavior subject. Meanwhile, the corresponding control strategy is proposed through the dynamic analysis of the evolution of quantum wave function.
风险是不确定的。通过违约风险来确定风险的影响是不可能的,而只能认识其存在的影响程度。在开放行为系统中,根据量子理论,风险反映在行为系统的波函数中,在风险时,系统的动态演化由系统哈密顿量中的环境哈密顿量决定。当环境与行为主体的特征值完全相关时,不影响其演化,风险是可控的。否则,风险将损害行为主体的进化。同时,通过对量子波函数演化的动态分析,提出了相应的控制策略。

A fine-grained image classification method based on generating adversarial networks with SIFT (Scale Invariant Feature Transform) texture input is proposed to improve the recognition ratio of fine-grained image classification by deep learning. For the phenomenon of data sets that require a large amount of labeled information for strong supervised learning, active learning capabilities of generative and adversarial networks and excellent image modeling capabilities for target classification images are used to achieve active learning of image features. Then the difficulty of data set construction and the computational complexity are reduced, and the disturbance to the network that may be caused by manually set labeled boxes is lessened. The input method of generating the adversarial network to is fixed to balance the authenticity and diversity of the generated samples. The idea of image restoration is considered. The random input method of the generative adversarial network that combines image feature points and random noise to is used to reduce the training difficulty of the generative and adversarial network. Experiments results show that our method outperformances the current deep learning methods in fine-grained image classification.

Objective to explore the nursing intervention points of postoperative hypoglycemia in elderly patients with endometrial cancer and diabetes mellitus. Method: 50 elderly patients with hypoglycemia after endometrial cancer and diabetes were selected. During the nursing process, the author made a detailed record and follow-up observation, and summarized the data. Result: After treatment, the condition of some patients were under control, including 44 cases with obvious effect, 4 cases with general effect, 2 cases with no effect, and the effective rate was 98%. Conclusion: In the clinical nursing of endometrial cancer patients with diabetes mellitus, effective nursing can greatly improve the recovery effect of patients, and can effectively control the deterioration of the disease, so efficient nursing methods can be popularized in clinical.
