Reconstruction from projections using dynamics: Non-Stochastic Case
Kevin R. Vixie, Gary L. Sandine
The problem of determining three-dimensional density fields from single two-dimensional projections is hopelessly underdetermined without additional assumptions. While parameterize…

The Bispectral Aliasing Test: A Clarification and Some Key Examples
Kevin R. Vixie, Murray Wolinsky, David Sigeti
Controversy regarding the correctness of a test for aliasing proposed by Hinich and Wolinsky has been surprisingly long-lived. Two factors have prolonged this controversy. One fact…

Detection of Aliasing in Persistent Signals
Kevin R. Vixie, David E. Sigeti, Murray Wolinsky
We explain why aliasing can be detected in a generic temporally-sampled stationary signal process. We then define a concept of stationarity that makes sense for single waveforms. (…
