Abstract
In the process of lightweight design of structures, the topology optimization method does not depend on the experience of designers, so it can design the optimal products more flexibly and creatively, which has become a hot issue in structural design. However, the current topological optimization results usually have problems such as difficult processing and high cost, which limit their wide application in engineering design. Therefore, this paper is based on the two-way progressive structure optimization method (BESO), considering the existence of jagged edges in the optimization results. In the finite element analysis of the fixed grid method, the boundary element is judged by the sensitivity of the element node, and the boundary element is localized divide and realize the partial deletion of the unit, so as to achieve a smooth boundary of the optimization result. The sensitivity of element nodes during structural flexibility optimization is deduced in detail, its basic principles and specific steps are explained, and finally the feasibility of this method is verified by an example.

Abstract
At present, with the rapid development of science and technology and the rapid development of computer related technology, with the development of this series of technologies, multimedia communication has rapidly become the means of communication and communication. Digital image technology, a very important form of information representation in multimedia communication, has now become a mainstream way. The technology provides more convenience for people's lives, but also has many problems, such as security, transmission and storage. For example, some images will involve personal privacy, business secrets, and even government secrets. In addition, the rapid transmission of information in limited bandwidth is also very important. Especially in the presence of cloud storage, it can not only store large amounts of information, such as files, videos and images, but also provide a large enough online space to store shared data. In this case, the real-time and security requirements of information transmission are higher and stricter. It is of great theoretical and practical significance to compress the image and reduce the bandwidth and ensure the security of image encryption. Image encryption is also called digital image encryption. Image compression is mainly based on the use of different technologies to change the pixel value and location of the image to protect the image. Image compression mainly compresses the image by removing redundant or unrelated information. In this paper, the concept of the variational self encoder is introduced firstly, and then the image compression and encryption based on the variational self coder generation model are studied and summarized briefly.

Published: January 2021

Abstract
To observe the effect of regulating qi and invigorate blood circulation method on hemorrheology in rats with acute blood stasis syndrome from the perspective of modern pharmacology, and use network pharmacology to explain its mechanism. Forty male Wistar rats were randomly divided into 6 groups. Except the blank control group, the other groups were injected with adrenaline hydrochloride and ice bath to establish the acute blood stasis syndrome model. Each group were administered Xuefu Zhuyu D ecoction, Jinlingzi Powder, Taohong Siwu Decoction, and Yanhusuo Decoction, and t he blank control group and model control group were given the same volume of saline, respectively. The blood rheology indexes such as red blood cell aggregation index of rats were measured. The TCMSP and Batman database were used to search for chemical components and targets of Jinlingzi Powder, and protein interaction analysis, GO enrichment analysis and KEGG analysis were performed on the common targets. The experimental results show that, compared with the model group, the blood rheology index levels of the Yanhusuo group and Taohong Siwu Decoction group are reduced, while the blood rheology index levels of the Xuefu Zhuyu Decoction group and the Jinlingzi S an group are significantly reduced. The network pharmacology predicts that Jinlingzi Powder has 44 active ingredients and 34 drug-disease shared targets, and KEGG analyzes 61 signaling pathways. Conclusion: IN the case of blood stasis syndrome, the effect of regulating qi with invigorate blood circulation is better than that of regulating qi alone. Network pharmacologic prediction showed that TNF signaling pathway was strongly correlated with hemorheology, and its action pathway was closely related to key tar gets IL6, TNF, CASP3.
