Generalized Impulse Response Analysis in Linear Multivariate Models¤

Building on Koop, Pesaran and Potter (1996), we propose the `generalized' impulse response analysis for unrestricted vector autoregressive (VAR) and cointegrated VAR models. Unlike the traditional impulse response analysis, our approach does not require orthogonalization of shocks and is invariant to the ordering of the variables in the VAR. The approach is also used in the construction of orde...

A Non-linear Technique for Room Impulse Response Estimation

Most techniques used to estimate the transfer function (or impulse response) of an acoustical space operate along similar principles. A known, broadband signal is transmitted at one point in the room whilst being simultaneously recorded at another. A matched-filter is then used to compress the energy in the transmission waveform in time, forming an approximate impulse response. Finally, equalis...

Impulse response recovery of linear systems through weighted cumulant slices

Identifiability of the so-called w-slice algorithm is proven for ARMA linear systems. Although proofs were developed in the past for the simpler cases of MA and AR models [2][6], they were not extendible to general exponential linear systems. The results presented in this paper demonstrate a unique feature of the w-slice method which is unbiasedness and consistency when order is overdetermined,...

Primary Breakup of Turbulent Round Liquid Jets in Uniform Crossflows

Anexperimental investigation of the deformation andbreakupproperties of turbulent round liquid jets in uniform gaseous crossflows is described. Pulsed shadowgraphandholographobservationswere obtained for turbulent round liquid jets injected normal to air crossflow in a shock tube. Crossflow velocities of the air behind the shock wave relative to the liquid jet were subsonic (36–90 m=s) and the ...
