In the 1970s and 1980s, the study of mental resilience emerged in the field of psychology in the United States and quickly became a hot topic in the field of international psychology. The field studies the psychological adaptation and development of children, adolescents (and later adults) in adversity. The extensive research on the psychological resilience of college students can enlighten the complexity of their psychological development. Throughout life, people inevitably encounter setbacks and adversities, and are under pressure from all sides at all times. With the development of society and the intensification of competition, college students are facing more and more pressure. Some college students can adapt to pressure and grow up healthily, while others cannot adapt to adversity, which leads to psychological problems. In the era of computer big data, relevant experience shows that physical exercise has certain help in forming mental resilience and positive emotions. Therefore, this paper analyzes the relationship between physical exercise, mental resilience and positive emotions of college students by using computer technology and mathematical model, so as to provide help for college students to form healthy psychology.
Objective: To explore the changes of college students’ lifelong sports consciousness before and after community interaction by using computer technology. Method: Research object and content. Five hundred students from three colleges and universities in Fujian Province were selected as the objects of investigation. 512 questionnaires were sent out and 500 were collected. T-check and Pearson check use computer technology to comprehensively analyze the collected data. Result: With the development of interactive sports activities between colleges and communities, the sports mode and consumption structure of college students have undergone profound changes. Conclusion: Community interaction is of positive significance to the cultivation of College Students’ lifelong sports consciousness.
Convolutional neural networks have been widely used in nondestructive testing of agricultural products. Aiming at the problems of missing detection, false detection, and slow detection, a lightweight improved cottonseed damage detection method based on YOLOv5s is proposed. Firstly, the focus element of the YOLOv5s backbone network is replaced by Denseblock, simplifying the number of modules in the backbone network layer, reducing redundant information, and improving the feature extraction ability of the network. Secondly, the collaborative attention (CA) mechanism module is added after the SPP pooling layer, and a large target detection layer is reduced to guide the network to pay more attention to the location, channel, and dimension information of small targets. Thirdly, Ghostconv is used instead of the conventional convolution layer in the neck feature fusion layer to reduce the amount of floating-point calculation and speed up the reasoning speed of the model. The CIOU loss function is selected as the border regression loss function to improve the recall rate of the model. Lastly, the model was verified using an ablation experiment and compared with the YOLOv4, Yolov5s, and SSD-VGG16 network models. The accuracy, recall rate, and map value of the improved network model were 92.4%, 91.7%, and 98.1%, respectively, and the average recognition time of each image was 97 fps. The results show that the improved network can effectively solve the problem of missing detection, reduce false detection, and have better recognition performance. This method can provide technical support for real-time and accurate detection of damaged cottonseed in a cottonseed screening device.
Abstract-The real estate trust as a new tool of financing, with its flexibility, has attracted a large amount of private capital, solving the financial problem effectively for the real estate developers. With the continuing updated macro-control measures and great changes of economy environment, how to explore the model of fund raising of the real estate trust with untraditional financial ideas has great significance on both theoretical and practical sides. In this article, the author casts out several suggestions to the development of the real estate industry of our country by referencing the conditions of developed countries. There are five important reorganizations in the history of the real estate trust in our country. However, there is still a long way to go on the task of reforming the real estate trust, as well as the whole monetary market. With referencing experience abroad and national conditions, the jobs related to the reform task should be done creatively and actively.
