2021 FEB 09 (NewsRx) By a News Reporter-Staff News Editor at Information Technology Daily Investigators publish new report on Information Technology - Data Recovery. According to news reporting originating in Guangzhou, People’s Republic of China, by NewsRx journalists, research stated, “In this paper, we focus on the false data injection attacks (FDIAs) on state estimation and corresponding countermeasures for data recovery in smart grid. Without the information about the topology and parameters of systems, two data-driven attacks (DDAs) with noisy measurements are constructed, which can escape the detection from the residue-based bad data detection (BDD) in state estimator.”

On December 23, MBA China released the ranking “TOP100 Best MBA Programs” and “TOP10 Best Finance MBA Programs” among all Chinese business schools in 2020. The ranking is based on key indicators such as faculty, curricula (including commercial thoughts, curriculum innovation, multidisciplinary integration, discipline foresight, intellectual capital, comprehensive effectiveness, and alumni resources), student evaluation, enrollment, brand influence, etc. They are currently the most authoritative and acceptable MBA school ranking lists in China.
Among the TOP100 Best MBA programs, the School of Economics and Management at Tsinghua University ranked the first. Antai School of Economics and Management at Shanghai Jiao Tong University and Guanghua School of Management at Peking University ranked the second and third respectively. The School of Management of Zhejiang University and the School of Management of Fudan University were strongly selected as the 4th

High cost, EMI issue

To take full advantage of a GaN transistor, the preferred requirements for isolated gate drivers are:
Maximum allowable gate voltage 7 V 100 kV/ms dv/dt at switching node, 100 kV/µs to 200 kV/µs CMTI
High-low switch delay match ≤50 ns for 650 V application
Negative voltage clamp (–3 V) for turning offThere are several solutions to drive both the high-side and low-side of the half-bridge transistor. One myth about the traditional, level-shifted, high voltage driver is that the simplest single-chip implementation is widely used only for silicon-based MOSFETs. In some high end products (for example, power supply for servers), the ADuM4223 dual-isolated driver is used to drive an MOS for compact designs. However, when turning to GaN, the level-shift solution has disadvantages, such as very large propagation delay and limited common-mode transient immunity (CMTI) and is not optimal for high switching frequency. The dual-isolated d
