Evaluation of Lightning Impulse Test by Frequency Response Analysis [PDF]

, 2006
In this work are presented the basis for improving the interpretation of transformer lightning impulse test and the development of a graphical user interface system, which allows comparisons of time domain data and frequency response.

Macroeconomic effects of reallocation shocks: a generalised impulse response function analysis for three European countries [PDF]

, 2003
We develop a generalised impulse response function (GIRF) approach to explore the different impacts of aggregate and sectoral shocks within a VAR-GARCH-M model.

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 ...

Critical Response of Single-Degree-of-Freedom Damped Bilinear Hysteretic System under Double Impulse As Substitute for Near-Fault Ground Motion

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

Eroding ribbon thermocouples: impulse response and transient heat flux analysis [PDF]

, 2005
We have investigated a particular type of fast-response surface thermocouple to determine if it is appropriate to use a one-dimensional transient heat conduction model to derive the transient surface heat flux from the measurements of surface temperature.

Critical earthquake response of elastic-plastic structures under near-fault ground motions (Part 2: Forward-directivity input)

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 factors affecting dominant acoustic impulse-response frequency of orange fruit based on grey relative theory

浙江大学学报. 农业与生命科学版, 2005
Using nondestructive acoustic impulse-response technique to evaluate the quality of oranges, it was found that there were lots of factors affecting dominant impulse-response frequency, such as mass, density, pH value, firmness and sugar content ...

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 ...
