Are PIIGS so different? An empirical analysis of demand and supply shocks [PDF]

Panoeconomicus, 2017
This paper analyses responses to supply and demand shocks in PIIGS countries. We compare the results obtained for PIIGS with those of Germany and the USA, and also with those of France, which despite its government’s efforts demonstrate ...

A Wavelet‐Based Test for Stationarity [PDF]

Journal of Time Series Analysis, 2000
We develop a test for stationarity of a time series against the alternative of a time‐varying covariance structure. Using localized versions of the periodogram, we obtain empirical versions of a reasonable notion of a time‐varying spectral density. Coefficients with respect to a Haar wavelet series expansion of such a time‐varying periodogram are an ...

Research on Iterative Learning Semi-active Control for Curve Passing of High-speed Train

机车电传动, 2020
When the high-speed train passes the curve, its dynamics performance deteriorates. In order to improve the dynamic performance of high-speed train when passing through different curves, the influence of semi-active control with yaw damper on its dynamic ...

Investments under non-stationarity: economic evaluation of adaptation pathways

Climatic Change, 2019
Investment decisions about capital-intensive, long-lived infrastructure are challenging due to uncertainty about their future performance, particularly if the performance is sensitive to climate change.

Stationarity of multivariate particle systems [PDF]

, 2013
A particle system is a family of i.i.d. stochastic processes with values translated by Poisson points. We obtain conditions that ensure the stationarity in time of the particle system in RdRd and in some cases provide a full characterisation of the ...
