“…The storage system inside the blockchain security technology uses a distributed storage structure, through the distributed cloud storage network, parties who need additional storage capacity can store data more securely and transparently, and import and export trading companies can access trade data information nearby to achieve high availability of data information. [15][16][17] Of course, in order to ensure the security of data information, cryptography is also used in blockchain security technology to protect the privacy of both parties in the transaction process and reduce the risk of tampering with trade data. 9 There are several algorithms in cryptography, among which is digital signature.…”

With the rapid development of globalization economy, countries in the world are more and more closely connected in business, and international import and export trade has also achieved rapid development. Based on the analysis of the status quo of the country's import and export trade, this article combines the main national economic indicators to analyze and study the algorithm of import and export trade forecasting. RVM is a sparse probability model and a new supervised learning method. Firstly, this paper introduces the protection system of block chain technology for import and export trade data information. Then, a hybrid RVM model is constructed, which is optimized by PSO algorithm, and the import and export volume is predicted based on this model. Based on the analysis of the data, it is tested that the security protection coefficient of the blockchain security technology for import and export trade data can reach up to 99.9%, and the accuracy of the import and export trade forecast based on the PSO optimized hybrid RVM model can reach up to 85.79%. A series of experiments show that the import and export trade forecast model studied in this paper can accurately predict the volume of import and export trade, thus providing a new method for the country's import and export trade, with high practical significance.

“…It needs for a successful solution comprehensive observations of various kinds with the mathematical treatment. A number of analytical and numerical mathematical models, available in the literature, can be used to fit ground deformation and gravity data to infer source location, depth and density as found in (Shandarin & Sathyaprakash, 1996;Battaglia & Hill, 2009).Understanding the local gravitational field and its accounting is important for monitoring the dynamic earth activity (like, volcanic) and correct interpretation of geodetic observations of various kinds (Stepanova et al, 2021;Mazurov & Pankrushin, 2006;Charco et al, 2007). Determination of the gravity field and its transforms are not trivial task, and often, to achieve the goal of the gravity should be make a combination of analytical descriptions of some elementary spatial bodies with subsequent finite element partition of a complex element of relief.…”

Gravity meters can be used to measure all effects that make up the Earth’s gravity field. Many of these effects are caused by known sources such as the Earth’s rotation, distance from the Earth’s center, topographic relief, and tidal variation. Physical fields are the main component of many centuries of the paradigm of all of Earth Sciences. The changing gravitational field is very important subject of research in the scientific aspect and practical. This paper applies two analytical models to simplify the gravitation calculation, which are sphere and cone models. Examples and finite element applications for the two models are studied also and discussed. The results of this study reveal that the possibility of using the proposed method with using presented analytical, finite element and numerical models to estimate the better determination of the characteristics of the local gravity of natural and man-made objects of sizes up to several tens of kilometers.
