Exploring river–aquifer interactions and hydrological system response using baseflow separation, impulse response modeling, and time series analysis in three temperate lowland catchments [PDF]
Hydrology and Earth System Sciences, 2022 Lowland rivers and shallow aquifers are closely coupled, and their interactions are crucial for maintaining healthy stream ecological functions. To explore river–aquifer interactions and the lowland hydrological system in three Belgian catchments, we ...

Impulse Response Identification Using Multiresolution Analysis
IFAC Proceedings Volumes, 1995 Abstract In this paper, the authors propose a new identification method for the discrete-time impulse response model of a linear system from sampled input-output data using multiresolution analysis theory. The continuous-time impulse response which is viewed as a L2(R) function of time, is approximated by scaling and wavelet functIons which are ...

Frontiers in Built Environment, 2018 A double impulse input is used as a substitute for near-fault earthquake ground motions. An explicit expression is derived on the maximum elastic–plastic response of a single-degree-of-freedom damped structure with bilinear hysteresis under the “critical

Generalized impulse response analysis: General or Extreme? [PDF]
econoquantum, 2013 This note discusses a pitfall of using the generalized impulse response function (GIRF) in vector autoregressive (VAR) models (Pesaran and Shin, 1998). The GIRF is general because it is invariant to the ordering of the variables in the VAR. The GIRF, in fact, is extreme because it yields a set of response functions that are based on extreme identifying

Frontiers in Built Environment, 2015 The triple impulse input is used as a simplified version of the forward-directivity near-fault ground motion and a closed-form solution of the elastic-plastic response of a structure by this triple input is obtained.

Analysis of an LMS algorithm for unbiased impulse response estimation [PDF]
IEEE Transactions on Signal Processing, 2003 In this correspondence, a least mean squares (LMS)-based algorithm is devised for unbiased system identification in the presence of white input and output noise, assuming that the ratio of the noise powers is known. The proposed approach aims to minimize the mean square value of the equation-error function under a constant-norm constraint and is ...

Ultra-Wideband Geo-Regioning: A Novel Clustering and Localization Technique
EURASIP Journal on Advances in Signal Processing, 2007 Ultra-wideband (UWB) technology enables a high temporal resolution of the propagation channel. Consequently, a channel impulse response between transmitter and receiver can be interpreted as signature for their relative positions.

Frontiers in Built Environment, 2015 The multiple impulse input is introduced as a substitute of the long-duration earthquake ground motion, mostly expressed in terms of harmonic waves, and a closed-form solution is derived of the elastic-plastic response of a single-degree-of-freedom ...
