Transient Stability of Voltage-Source Converters With Grid-Forming Control: A Design-Oriented Study
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 Driven by the large-scale integration of distributed power resources, grid-connected voltage-source converters (VSCs) are increasingly required to operate as grid-forming units to regulate the system voltage/frequency and emulate the inertia.

The Zwicky Transient Facility: Data Processing, Products, and Archive [PDF]
Publications of the Astronomical Society of the Pacific, 2018 The Zwicky Transient Facility (ZTF) is a new robotic time-domain survey currently in progress using the Palomar 48-inch Schmidt Telescope. ZTF uses a 47 square degree field with a 600 megapixel camera to scan the entire northern visible sky at rates of ...

Journal of the American Academy of Orthopaedic Surgeons, 2008 Transient osteoporosis is characterized primarily by bone marrow edema. The disease most commonly affects the hip, knee, and ankle in middle-aged men. Its cause remains unknown. The hallmark that separates transient osteoporosis from other conditions presenting with a bone marrow edema pattern is its self-limited nature. Laboratory tests usually do not

Terminal Transient Phase of Chaotic Transients
Physical Review Letters, 2018 Transient chaos in spatially extended systems can be characterized by the length of the transient phase, which typically grows quickly with the system size (supertransients). For a large class of these systems, the chaotic phase terminates abruptly, without any obvious precursors in commonly used observables.

OT 060420: A Seemingly Optical Transient Recorded by All-Sky Cameras [PDF]
, 2006 We report on a ~5th magnitude flash detected for approximately 10 minutes by two CONCAM all-sky cameras located in Cerro Pachon - Chile and La Palma - Spain. A third all-sky camera, located in Cerro Paranal - Chile did not detect the flash, and therefore

IEEE transactions on industrial electronics (1982. Print), 2021 Attributed to the ability of inertia provision and good regulation performance, the virtual synchronous generator (VSG) has been proven as a promising solution to the problems introduced by using converter interfaced generation. Although the small-signal
