Volatility impulse response analysis for DCC‐GARCH models: The role of volatility transmission mechanisms [PDF]

open access: yesJournal of Forecasting, 2020
AbstractThis study introduces volatility impulse response functions (VIRF) for dynamic conditional correlation–generalized autoregressive conditional heteroskedasticity (DCC‐GARCH) models. In addition, the implications with respect to network analysis—using the connectedness approach of Diebold and Y lmaz (Journal of Econometrics, 2014, 182(1), 119–134)

Ultra-Wideband Geo-Regioning: A Novel Clustering and Localization Technique

open access: yesEURASIP 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.

The Finite-Precision Numerical Effects Analysis of Infinite Impulse Response

open access: yesOALib, 2019
This paper mainly uses the MATLAB software to design IIR digital filter with the amplitude frequency characteristic method and zero-pole method, and then analyzes the effect of coefficient quantization and quantization effects in IIR digital filter arithmetic. It is that we can use the software to draw some pictures. These pictures can show coefficient

Critical input and response of elastic-plastic structures under long-duration earthquake ground motions

open access: yesFrontiers 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 ...
