Lithium battery has been employed widely in many industrial applications. Parameter mismatches between lithium batteries along a series string is the critical limits of the large-scale applications in high power situation. Maintaining equalization between batteries is the key technique in lithium batteries application. This paper summarizes normal equalization techniques and proposed a new type of lithium Battery Equalization and Management System (BEMS) employing the isolated DC-DC converter structure. The system is integrated both equalization functions and management functions by using distributed 3-level controlled structure and digital control technique. With this control method the flexibility of the balance control strategy and the compatibility for different battery strings are both improved dramatically. The experimental results show optimizing equalization, efficiency and the battery string life span has been extended.

Learning Management

Online education helped resume learning that had come to a momentary and uncertain pause with the onset of COVID-19 pandemic across the globe. Since then, learning in many educational institutions continued through synchronous and asynchronous modes, with teaching being undertaken remotely on digital platforms. In this large-scale migration towards online mode of curriculum delivery induced by the pandemic, the institutional learning management system (LMS) had a critical role to play in ensuring uninterrupted learning and student engagement. By drawing heavily from extant works, learnings from MOOC platforms, observations from the LMS applications in corporate training, the present article synthesis the extant literature on how the effective use of LMS can make the learning process interactive, student centric, catering to the needs of diverse learners in higher education.

This paper presents a system in which the cluster devices are controlled by single-chip microcomputers, with emphasis on the cluster management techniques of single-chip microcomputers. Each device in a cluster is controlled by a single-chip microcomputer collecting sample data sent to and driving the device by driving data received from the same cluster management computer through COMs. The cluster management system running on the cluster management computer carries out such control as initial SCM identification, run time slice management, communication resource utilization, fault tolerance and error corrections on single-chip microcomputers. Initial SCM identification is achieved by signal responses between the single-chip microcomputers and the cluster management computer. By using the port priority and the parallelization of serial communications, the systems real-time performance is maximized. The real-time performance can be adjusted and improved by increasing or decreasing COMs and the ports linked to each COM, and the real-time performance can also be raised by configuring more cluster management computers. Fault-tolerant control occurs in the initialization phase and the operational phase. In the initialization phase, the cluster management system incorporates unidentified single-chip microcomputers into the system based on the history information recorded on external storage media. In the operational phase, if an operation error of reading and writing on a single-chip microcomputer reaches a predetermined threshold, the single-chip microcomputer is regarded as serious fault or not existing. The cluster management system maintains accuracy maintenance database on external storage medium to solve nonlinear control of specific devices and accuracy maintenance due to wear. The cluster management system uses object-oriented method to design a unified driving framework in order to enable the implementation of the cluster management system simplified, standardized and easy to transplant. The system has been applied in a large-scale simulation system of 230 single-chip microcomputers, which proves that the system is reliable, real-time and easy to maintain.

The article considers the concept of "risk in railway transport", identifies the types of risks that exist in the railway transport of Ukraine; determined that the processes of transformation of economic relations in Ukraine require the deepening of theoretical and practical developments in risk management in the field of railway transport; the risk management process according to the ISO 31000: 2018 standard is given; according to the implemented Strategy and Policy of JSC "Ukrzaliznytsia" the main tasks of the risk management system are defined and the risk map of JSC "Ukrzaliznytsia" is developed; The results of the structural reform of railway transport were insufficient to create effective sources of development in the short term, which will ensure large-scale attraction of funds for the development of the industry and its modernization. The results of the structural reform of railway transport were insufficient to create effective sources of development in the short term, which will ensure large-scale attraction of funds for the development of the industry and its modernization. Many types of risks that need to be assessed, as well as different purposes of assessing the same type of risk (for the purposes of state supervision and company purposes) provide JSC "Ukrzaliznytsia" a real challenge in terms of building risk assessment models. The task of applying the method of assessing a specific type of risk is significantly different from the task of building a methodology for assessing the risks of a large company. In solving this problem, it is important to keep in mind that a method successfully applied in one area may be completely ineffective in another. Risk classification of JSC "Ukrzaliznytsia" should be carried out taking into account the existing management structure, as well as the tasks to be solved at each level of management; the effect of the risk management system should be synergistic, each element of each level of management should be effective: from the structural unit at the linear level to the department of the corporate level of management. Currently, for the company's internal purposes, several dozen risks have been formulated related to various areas of life of JSC UZ: from financial activities to locomotive maintenance and innovative development.

The article considers the project management system as a tool for achieving strategic goals of network trading companies. This study is relevant, because in retail project management is widely used to solve unique and large-scale business problems, but the degree of prevalence of the project approach is still low, which affects the income of companies. In the course of the research, the classification of the activities of network trading companies, the functional-oriented organizational structure of project management of a network trading organization is presented, the model of the business architecture of project management of a network trading company is developed, and the algorithm of selection and the main functions of the software for project management are considered. As a result of the research, a standard project portfolio and a top-level model of the business architecture of a network trading company with an implemented corporate project management system were developed.
