- Developing the Dynamic Hazard-Based Safety Engineering by Introducing the Control-Oriented ModelThis article will illustrate why it is necessary to introduce the control-oriented model to hazard-based safety engineering (HBSE), based on a typical large core switching fan-tray architecture design and related failure model. The authors also provide detailed design and evaluation guidelines, which can ensure the control of random hardware failure and avoid systematic failure (both hardware and software), then achieve the safety target (i.e., safety integrity level).
- Introduction to Fault-Managed PowerFault-managed power systems transmit higher voltages safely by detecting faults and halting power within milliseconds. This ISPCE 2025 Best Paper Award winner introduces the technology's origins, infrastructure applications, compliance standards, and advantages over traditional AC distribution.
