Transient signal detection using GPS position time series
… with millimeter-level accuracy and have revealed transient deformations on various spatial and temporal scales. However, the transient deformation may not be easily identified from the position time series because of low signal-to-noise ratios (SNR), correlated noise in space and time and large …

Parameter recovery for transient signals
Transient signals naturally arise in numerous disciplines for which the decay rates and amplitudes carry some informational significance. Even when the decay rates are known, solving for the amplitudes results in an ill-conditioned formulation. Transient signals in the presence of noise are further …

The transient response of bedrock river networks to sudden base level fall
… in the factors that determine landscape form, a transient signal of adjustment propagates through the river network, progressively adjusting channels and hillslopes to the new conditions. When conditions favor incision, the rate and mechanism by which this signal propagates throughout the network …

Fiber Optic Sensors for Liquid Identifications
… optical fiber tip sensors and monitored the time-transient responses of the evaporating droplets. Inspired by the evaporation dynamics of liquids, we employed machine learning techniques to efficiently extract valuable information from the evaporation time-transient signals of liquid pendant …

The thermal regime of the Eastern Alps along the TRANSALP profile
… and exhumation was estimated, performing 1-D transient forward simulation and an analytical approach. The main paleoclimatic signal of -6.5 K was detected in a depth of 2 km. As exhumation leads to an elevation of temperature that increases with depth, the resulting transient signal in the …
