Prediction of Mineralization Prospects Based on Geological Semantic Model and Mobile Computer Machine Learning

Mineral resources are indispensable in the development of human society and are the foundation of national economic development. As the prospecting target shifts from outcrop ore to concealed ore, from shallow to deep, the difficulty of prospecting becomes more and more difficult. Therefore, the prediction of mineralization prospects is of great significance. This paper is aimed at completing the prediction of mineralization prospects by constructing geological semantic models and using mobile computer learning to improve the accuracy of prediction of mineralization prospects and expanding the application of semantic mobile computing. We use five different semantic relations to build a semantic knowledge library, realize semantic retrieval, complete information extraction of geological text data, and study mineral profiles. Through the distributed database of mobile computing, the association rules and random forest algorithm are used to describe the characteristics of minerals and the ore-controlling elements, find the association rules, and finally combine the geological and mineral data of the area and use the random forest algorithm to realize the prospect of mineralization district forecast. The geological semantic model constructed in the article uses the knowledge library for associative search to achieve an accuracy rate of 87.9% and a recall rate of 96.5%. The retrieval effect is much higher than that of traditional keyword retrieval methods. The maximum value of the posterior result of the mineralization prospect is 0.9027, the average value is 0.0421, and the standard deviation is 0.1069. The picture is brighter, and the probability of mineralization is higher.

Method of ensuring the survivability of highly mobile computer networks

The article discusses the features of the functioning of mobile computer networks based on small-sized aircraft (highly mobile computer networks). It is shown that such networks, in contrast to stationary or low-mobile ones, have a low level of survivability in case of local damage to their nodes. The purpose of the article is to develop a method for ensuring the survivability of highly mobile computer networks under conditions of destructive external influences, which leads to local destruction of network nodes or links between them, using the method of assessing survivability at all stages of network functioning, by changing the main function to implement all available strategies for the functioning of the network when determining the critical values of the integrity of the network and its ability to perform at least one of the available functions. The results obtained allow: to continue the development of theoretical research in the development of strategies for managing highly mobile computer networks in extreme situations; to develop an applied solution to ensure the survivability of highly mobile computer networks by building multifunctional or redundant structures, increasing the value of their redundancy. The studies allow us to conclude that the proposed method can be used at the design stages of highly mobile computer networks, characterized by increased survivability and capable of functioning in conditions of multiple local damages without catastrophic destructive consequences for the network structure.

We the Gamers

The world is in crisis. The people of the world are all connected, and rely on one another to make ethical decisions and to solve civic problems together. Ethics and civics have always mattered, but it is becoming more evident how much they matter. Teaching ethics and civics is essential to the future. This book argues that games can encourage the practice of ethics and civics. They can help people to connect, deliberate, reflect, and flourish. They can help people to reimagine systems and solve problems. Games are communities and public spheres. Like all communities, they may encourage care, connection, and respect. They may also be used for hate, disinformation, and exclusion. Games reveal humanity’s compassion as well as its cruelty. We the Gamers provides research-based perspectives related to why and how people should play, make, and use games in ethics, civics, character, and social studies education. The book also shows how people are already engaging in ethics and civics through games. It systematically evaluates how to use games in classrooms, remote learning environments, and other educational settings, with consideration to different audiences and standards. This book also provides tips and guidelines, as well as resources, activities, and case studies. It includes examples of all different types of games—virtual reality, mobile, computer, and card games, and big-budget commercial games, indie games, and more. How can people play and design a new world, together?

CONTOUR METHOD FOR POSITIONING OBJECTS IN MOBILE COMPUTER VISION SYSTEMS

The paper considers the possibility of solving the problem of improving the quality of technical vision using the contour method, which is used to position objects in mobile computer vision systems. The hardware part of the object positioning system includes two video cameras, a Raspberry Pi 3 microcomputer, a depth contour map screen, and a motor control unit. The codes of programs based on the OpenCV library, the algorithm of the system and examples of the implementation of the contour method are given. The algorithm of the developed positioning technique includes the selection of the contours of objects on the frames of a stereopair, removal of all open contours, calculation of the moment (center of mass) of each closed contour, determination of the displacement along the x-axis of the moments of the corresponding contours, filling each closed contour with points with a brightness inversely proportional to the displacement of the moments. The presence of two video cameras, a Raspberry Pi 3 microcomputer, a contour depth map screen provides stereoscopic and panoramic "vision", that is, the ability to determine the presence of objects and their distance, as well as to get an overall picture in the "field of view" of the system. The engine control unit allows mobile devices to avoid obstacles. Based on the analysis of the research results, it was found that the proposed system provides an increase in the quality of positioning of objects and a decrease in the required computing resource, which gives a significant decrease in power consumption and ensures the autonomy of the system.

ImplantoPUC: an educational application for mobile computing devices aimed at patients and professionals in the field of Implantology

ABSTRACT Objective: development of an application for mobile computer devices, mobile phones and tablets, which contains educational material for patients and professionals in the area of Implantology. The use of ImplantoPUC at PUC Minas implant dentistry clinics aims at a more effective communication between professionals and patients, with better visualization of the proposed treatments, improving the understanding of patients. Methods: for the development of ImplantoPUC, a responsive technology was used, and the application windows can adapt to different screen formats, consequently, the application can be made available on different platforms such as: Web, Android and Apple. The application size is 13.4 MB and was developed using the OutSystems platform using Apache Cordova. The prototype of the ImplantoPUC application can already be accessed through the link https://includesistemas.outsystemcloud.com/implantpuc/homescreen. Results: the application is still under test at PUC Minas implant dentistry clinics, but due to the pandemic its use is still below expectations. In the Play Store your rating has a maximum rating of 5.0, with more than 50 downloads so far. Conclusion: Implanto PUC makes the task of informing more interactive and easy to understand for patients, also assisting professionals in the area in obtaining updated information and at the reach of hands, and can also be used in other Dentistry Educational Institutions, becoming a reference in the area of implant dentistry.
