Федеральное государственное бюджетное образовательное учреждение высшего образования «Национальный исследовательский Мордовский государственный университет имени Н. П. Огарева», г. Саранск, Россия, тел. (834) 25 44 05, e-mail: [email protected] Электронные карты необходимы для измерения площади полей и создания цифровой среды, с которой работают остальные компоненты точного земледелия. Для практической реализации был выбран метод отрисовки полей с помощью специальных программ на базе операционной системы ANDROID. Наиболее оптимальными, с точки зрения функциональных возможностей были определены программы «GPS Area» от компании News Marathon Ltd, «Навигатор полей» от компании Farmis и «Field Bee» от компании е Farmer BV. Для создания электронных карт полей с помощью метода отрисовки программами на базе операционной системы ANDROID лучше использовать более сложные системы параллельного вождения, которые позволяют не только сохранять поля, но и имеют функции экспорта карт, передачи, изменения единиц измерения. Данные системы позволяют комбинировать функции отрисовки и объезда полей, а также подсоединять внешнюю антенну GPS для увеличения точности измерений. При этом было выявлено, что программы курсоуказатели не отрисовывают и не создают электронные карты полей, а служат лишь для нанесения параллельных контуров и трекеров на бесконечное виртуальное поле приложения. Числовой расчет оптимального критерия выбора показал, что наиболее эффективной является программа «Навигатор полей» с критерием выбора Z = 5,01. На основе исследований программного обеспечения на операционной системе ANDROID разработаны практические рекомендации. Electronic maps are necessary to measure the area of fields and create a digital environment with which the rest of the components of precision agriculture work. For practical implementation, the method of rendering fields using special programs based on the ANDROID operating system was chosen. The programs «GPS Area» from News Marathon Ltd, «Field navigator» from Farmis and «Field Bee» from е Farmer BV were determined to be the most optimal in terms of functionality. To create electronic maps using the method of rendering programs based on the ANDROID operating system, it is better to use more complex parallel driving systems which allow not only to save fields, but also have the functions of exporting maps, transferring, and changing units of measurement. These systems allow combining the functions of rendering and detouring fields, as well as connect an external GPS antenna to increase the accuracy of measurements. Herewith, it was found out that the course indicator programs do not render or create electronic maps, but only serve to draw parallel lines and trackers onto the limitless virtual field of the application. Numerical analysis of the optimal selection criterion showed that the most effective program was "Field navigator" with the selection criterion Z = 5,01. Based on the research of software on the ANDROID operating system, practical recommendations have been developed.

This research produced an Palembang Exlore application which is an application for tourism promotion in Palembang City. Tourism here is not only historical sites, but also can be other tours, including historical or famous places / buildings in a city, where you can buy souvenirs or souvenirs, where to buy special foods from a region or culinary, and so on. This application is useful for tourists, both domestic and foreign who will visit the city of Palembang. So that tourists are expected to know all the tourist attractions that can be visited, ranging from tourist places or historic buildings to culinary tours of the city of Palembang. The method used in making this application or software uses the Extreme Programming method which consists of several stages, namely planning, design, coding and testing. The application is made using HTML 5 programming language. This application is used through the Android operating system

This paper evaluates the performances of numerous encryption algorithms on mobile devices running the Android operating system. The primary objective of our research was to measure and compare the relative performances of tested algorithm implementations (Data Encryption Standard (DES), 3DES, Advanced Encryption Standard (AES), ChaCha20, Blowfish, and Rivest Cipher 4 (RC4)) on the Android platform. The algorithms were compared in terms of CPU utilization by measuring the time required to encrypt and decrypt variable size text files. Besides evaluating the six common symmetric encryption ciphers, a comparison has been conducted for several Password-Based Encryption (PBE) algorithms. Diverse cipher transformations were evaluated for each algorithm by utilizing various feedback modes and padding schemes. Two smartphone devices were used for testing, with different versions of the Android operating system and hardware specifications. The summarized performance outcomes for various cipher transformations are presented to demonstrate the effectiveness of each algorithm.

Robots imitating spider’s moving have many advantages such as flexible movement, high stability, diversity in movements performed, especially in terrain  crossing, in military reconnaissance, in surveying and collecting environmental data in dangerous areas,.... In this article  with the main objective is to exploit multiple control methods to support applications of a spider robot with low-cost, a spider robot with 6 legs and 18 joints was designed. The ESPWROOM-32 module (ESP32-D0WDQ6 chip) and MIT App Inventor were used as the main tools for conducting this research. As a result, the robot is controlled via Bluetooth and Wifi to move, making some actions by self-written software running on the Android operating system. In addition, the robot has the capacity of self-propelled to avoid simple obstacles and send some environmental parameters to the software, including obstacles distance, humidity and temperature.

Android is a mobile device on the operating system for mobile phones based on Linux, android provides an open platform for developers to create applications. Android-based application developers make applications so that they can be useful for the community ranging from game genre applications, education, entertainment and simulation applications that are very likely to be created and run on this android operating system. Simulation is the process of designing a matemastis or logical model of a real system, conducting experiments on models using computers to describe, explain and predict system behavior. For a simulation application company can be used as a medium of product promotion, while for smartphone users can help to channel the existing imagination into a real picture. The application of simulation applications many functions, one example of its application to two-wheeled motor vehicles. By utilizing android application and the growth of vehicle users that lead to the hobby of modification, it can be utilized by creating an android-based coloring simulation application to help modifiers and modification lovers in order to channel their imagination and make it easier to design colors as desired. Without having to bother using design software that requires special skills
