Abstract

Recently, the world has witnessed the most severe pandemic (COVID-19) in this century. Studies on epidemic prediction and simulation have received increasing attention. However, the current methods suffer from three issues. First, most of the current studies focus on epidemic prediction, which can not provide adequate support for intervention policy making. Second, most of the current interventions are based on population groups rather than fine-grained individuals, which can not make the measures towards the infected people and may cause waste of medical resources. Third, current simulations are not efficient and flexible enough for large-scale complex systems. In this paper, we propose a new epidemic simulation framework called HMES to address the above three challenges. The proposed framework covers a full pipeline of epidemic simulation and enables comprehensive fine-grained control in a large scale. In addition, we conduct experiments on real COVID-19 data. HMES demonstrates more accurate modeling of disease transmission up to 300 million people and up to 3 times acceleration compared to the state-of-the-art methods., Comment: UIC-2022, code available at https://github.com/hygeng/humanflow

Abstract

With the development of the intelligent substation technology, the centralized protection attracts more and more attention of Chinese scholars. Due to the implementation of IEC61850, the development of the high-speed Ethernet, and the advanced performance of computer hardware, the centralized protection becomes a possible choice. Centralized protection simplifies the traction substation secondary wiring, and realizes real time data sharing. It avoids the repeated configuration of hardware, and reduces the space required for the installation of protection devices. Under the consideration of these advantages, the centralized protection will be the main trend for micro-computer protections for traction substations. Compared with and traditional protection, this paper discusses the schemes for the centralized protection for the hybrid dual redundant star network is discussed, and illustrates the design and reliability for these schemes.
