LINEAR TRUNCATIONS OF THE HILBERT TRANSFORM [PDF]
Real Analysis Exchange, 1996 The author considers the operator \(H_{a,b,c,d}f(x)=\int_{ax+b}^{cx+d} dt/t\) arising in connection with questions about bilinear operators of type \(\int_{R^1}g(t-ax)f(x-t) dt/t\), generalizing the Hilbert transform, but for \(a\neq 0\) being no convolutions.

Fire Histories and Rainforest Aboriginal Archaeology in the Wet Tropics Bioregion, North Queensland
Archaeology in Oceania, EarlyView.ABSTRACT Unlike the dominant Australian savanna‐sclerophyll vegetation, tropical rainforests do not burn easily. Any evidence of fire in Australian rainforests therefore invites explanations of its source. Analysis of 187 radiocarbon dates that include selected charcoal fragments from 23 soil pits and 7 archaeological sites from the Wet Tropics ...

How do you make a time series sing like a choir? Using the Hilbert-Huang transform to extract embedded frequencies from economic or financial time series [PDF]
The Hilbert-Huang transform (HHT) was developed late last century but has still to be introduced to the vast majority of economists. The HHT transform is a way of extracting the frequency mode features of cycles embedded in any time series using an ...

No‐regret and low‐regret control for a weakly coupled abstract hyperbolic system
Asian Journal of Control, EarlyView.Abstract This paper explores an optimal control problem of weakly coupled abstract hyperbolic systems with missing initial data. Hyperbolic systems, known for their wave‐like phenomena and complexity, become even more challenging with weak coupling between subsystems.

A probabilistic diagnostic for Laplace approximations: Introduction and experimentation
Canadian Journal of Statistics, EarlyView.Abstract Many models require integrals of high‐dimensional functions: for instance, to obtain marginal likelihoods. Such integrals may be intractable, or too expensive to compute numerically. Instead, we can use the Laplace approximation (LA). The LA is exact if the function is proportional to a normal density; its effectiveness therefore depends on ...
