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

Impulse response function analysis of the impacts of hospital accreditations on hospital efficiency [PDF]
Improving hospital efficiency is an emerging area of interest among policy makers in the new global economy's healthcare system. To ensure accurate efficiency analyses, we consider the nonhomogeneous input/output characteristics of various hospital departments, particularly the Department of Medicine, Department of Surgery, and Department of Other ...
