Novel MMC Sub-Module Topology With DC Fault Clearing Capability

IEEE Access
The traditional half bridge sub-module (HBSM) cannot clear the DC side fault by itself. On the other hand, the clamp double sub-module (CDSM) has the ability to self-clear the fault current, but it can only output the negative level of the single ...

Non-invasive monitoring and control in silicon photonics by CMOS integrated electronics [PDF]

, 2014
As photonics breaks away from today's device level toward large scale of integration and complex systems-on-a-chip, concepts like monitoring, control and stabilization of photonic integrated circuits emerge as new paradigms.

Aileron Locking Fault Detection Based on Extended Kalman Filter for UAV

Proceedings of the 3rd International Conference on Vision, Image and Signal Processing, 2019
This paper presents application of Nonlinear Extended Kalman Filter for aileron actuator locking scenario in Unmanned Aerial Vehicles and estimation of states to make comparison between sensor results and estimation results. At first, nonlinear state space system of UAV is formulated.

Plate coupling and strain in the far western Aleutian arc modeled from GPS data

Geophysical Research Letters, 2017
The Aleutian and Kuril‐Kamchatka arcs meet at a triple junction of the Pacific (PAC), Bering (BER), and North American (NAM) plates. We invert GPS observations from the westernmost Aleutian (Komandorsky) Islands and Kamchatka for the fault locking depth ...

Distributed Lower‐Crustal Flow Beneath the Central Xianshuihe–Xiaojiang Fault System: Reconciling Geodesy and Geology

Geophysical Research Letters
We use recently compiled GNSS velocities across the Zemuhe‐Daliangshan fault zone, part of the central Xianshuihe‐Xiaojiang fault system, to reconcile a long‐standing mismatch between geodetic and geologic slip‐rate estimates.

Geodetic slip rate and seismogenic depth of unmapped active faults in Yogyakarta, Indonesia, inferred from dense Global Navigation Satellite System campaign observation

Geodesy and Geodynamics
Yogyakarta was struck by a devastating MW6.3 earthquake, which intensified awareness about the seismic hazards in the region. This study investigates the kinematic slip rate and seismogenic depth of the northern segment of Opak Fault and an unmapped ...

Continental breakup and UHP rock exhumation in action: GPS results from the Woodlark Rift, Papua New Guinea [PDF]

, 2015
We show results from a network of campaign Global Positioning System (GPS) sites in the Woodlark Rift, southeastern Papua New Guinea, in a transition from seafloor spreading to continental rifting. GPS velocities indicate anticlockwise rotation (at 2–2.7°

Deformation Distribution Characteristics and Seismic Hazard of the Xianshuihe Fault Zone Based on GNSS and InSAR Data

Applied Sciences
The spatial distribution characteristics and slip rate in the Xianshuihe Fault Zone (XSHFZ) are still subject to controversy, and the segments where creeping movement occurs within the fault remain unclear.
