ELoran Propagation Delay Prediction Model Based on a BP Neural Network for a Complex Meteorological Environment [PDF]
Sensors, 2023 The core of eLoran ground-based timing navigation systems is the accurate measurement of groundwave propagation delay. However, meteorological changes will disturb the conductive characteristic factors along the groundwave propagation path, especially ...

Delay Correction Method Based on VLF Timing Signal Phase Variation Model [PDF]
SensorsPositioning, navigation, and timing (PNT) services require stable time transfer, but satellite-based PNT signals are vulnerable to interference, attenuation, and limited availability in constrained environments. Very-low-frequency (VLF) signals propagate

A Review of Research on Flight Delay Propagation: Current Situation and Prospect
Journal of Advanced TransportationThe correlation between flight routes makes the initial delays easy to cause chain delays of downstream airports, forming a large area of delays. Studying delay propagation can block its propagation path and alleviate large-scale delay problems.

Mitochondria delay action potential propagation
Communications BiologyThe internal resistance of axons to ionic current flow determines action potential conduction velocity. Although mitochondria support axonal function, axons have been modeled as organelle-free cables, and mitochondrial impact on conduction velocity ...

Minimum propagation delays in VLSI [PDF]
IEEE Journal of Solid-State Circuits, 1982 Conditions are outlined under which propagation delays in VLSI circuits can be achieved that are logarithmic in the wire lengths. These conditions are imposed by area requirements and the velocity of light.

A Spatial–Temporal Network Perspective for the Propagation Dynamics of Air Traffic Delays
Engineering, 2021 Intractable delays occur in air traffic due to the imbalance between ever-increasing air traffic demand and limited airspace capacity. As air traffic is associated with complex air transport systems, delays can be magnified and propagated throughout ...
