In order to better meet the needs of home sprouts cultivation and improve the convenience and appreciation of user management, a three-dimensional cultivation device for home sprouts was designed. The device consists of a frame structure, a cultivation system, a water supply system, and a light supplement system, a control system and other components. A simulation analysis was carried out using SolidWorks, and the results showed that the strength of each part can meet the force requirements, the irrigation water can flow into each cultivation trough smoothly, and the water supply in each trough is even. The prototype application test results show that: it can meet the cultivation requirements of sprouts, and the cultivation effect is better than ordinary three-dimensional cultivation devices, and the management convenience, ornamental, and comprehensive user satisfaction are also better than ordinary three-dimensional cultivation devices. The device can provide a certain reference value for related designs, and has broad promotion prospects in the field of home sprout vegetable cultivation.

In view of the low security of the management accounting online teaching system, this paper puts forward the design of the management accounting online teaching system based on virtual simulation technology. The overall module of management accounting online teaching system is designed by using virtual simulation technology. Combined with the detailed design of online classroom module, video management module, course management module and user management module, the design of management accounting online teaching system is realized. The test results show that the online teaching system of management accounting based on virtual simulation technology meets the expected results and has higher security.

In order to better meet the needs of home sprouts cultivation, and improve the convenience and appreciation of user management, a home ultrasonic sprouts cultivation device is designed, which consists of a base, an atomization system, a cultivation tank, a light supplement system, and a control system and other components. Simulation analysis was carried out using SolidWorks, and the results showed that the strength of each part can meet the force requirements, the water spray generated by the ultrasonic atomizer can flow into each cultivation trough smoothly, and the amount of spray in the trough is uniform. The prototype application test results show that: it can meet the cultivation requirements of sprouts, and the cultivation effect is better than ordinary three-dimensional cultivation devices, and the management convenience, ornamental, and comprehensive user satisfaction are also better than ordinary three-dimensional cultivation devices. This paper proposes the use of ultrasonic atomization to cultivate sprouts, which can provide a certain reference value for related design, and has broad promotion value in the field of home sprouts cultivation.

This paper proposes a novel software architecture for developing disease registries. Our proposal consists of five horizontal layers and two transversal layers. It takes into account several aspects of disease registries, such as various sources of data acquisition, security and privacy issues, data analytics, and user management tasks. Several use cases are presented: the Tunisian Fanconi Anemia Registry (TFAR), the Tunisian Gaucher Disease Registry (TGDR), the Tunisian Non-Hodgkin Lymphoma Registry (TNHLR), and the Tunisian Registry of Diabetes Type 1 (TRD-T1).

Aiming at the poor performance of the traditional college basketball course networked teaching system, with the purpose of improving the performance of college basketball course networked teaching system, a virtual reality-based college basketball course networked teaching system is designed. Through the user registration module design, the question answering module design and the student user management module design, the hardware design of the system is completed, and the software design of the system is completed through the management of college basketball course resources and the design of the student basketball course homework management program. The design of the networked teaching system of the course. The test results show that the network teaching system of College Basketball Course Based on virtual reality has reached the design requirements and has higher performance.

Traditionally remote laboratories are developed by utilizing personal computers (PC) or workstations as the main controller unit on the experiment side and a local server for database and user management. However, given the emergence of new technologies, embedded processors are becoming more powerful, faster, and resourceful. It is now possible to replace personal computers or workstation with embedded processor boards. In addition, remote laboratory Based on this scenario, this paper reports the development of several remote experimentation facilities in which embedded processors and cloud are utilized to replace PCs and local servers.

Online examination has been used more and more widely in the education and other fields due to its advantages of efficiency, convenience, and fairness. This paper proposes a new web-based online examination system, which utilizes PHP, Ajax and other technologies to implement online examination functions, including testing question collection, user management, online testing, real-time score calculation, answer checking, and result analysis. Particularly, an automated test paper generation module was designed and integrated. The system has been applied to a course involving more than 1000 students per semester at Guangzhou University of Foreign Studies. It has been proved to save efforts of teachers and students, demonstrating its effectiveness in assisting teaching and learning.

A problem that students find in some subjects is to find online educational resources on their content that have adequate quality. This paper presents a tool that allows a teacher to create in a simple way educational resources using their own material or automatically extracted from repositories of open data or linked data. In addition, the tool offers a user management system that allows a student to register with a specific teacher, so that they can access all the resources published by a specific teacher. Educational resources can be downloaded from the tool in order to be used non-online. In the article, the proposal has been illustrated in the context of the subject of Software Engineering.

Revocable Hierarchical Identity-Based Encryption (RHIBE) is a variant of Identity-Based Encryption (IBE), which enables the dynamic user management; a Key Generation Center (KGC) of a usual IBE has a key issuing ability. In contrast, in a RHIBE, a KGC can revoke compromised secret keys and even delegate both key issuing ability and revocation ability.

This paper describes problems that arose with the scaling and internationalization of the open source project Catrobat. The problems we faced were the lack of a centralized user management, insufficient scaling of our communication channels, and the necessity to adapt agile development techniques to remote collaboration. To solve the problems we decided to use a mix of open source tools (Git, IRC, LDAP) and commercial solutions (Jira, Confluence, GitHub) because we believe that this mix best fits our needs. Other projects can benefit from the lessons we learned during the reorganization of our knowledge base and communication tools, as infrastructure changes can be very labor-intensive and time-consuming.
