Positive Time-Frequency Distributions via Quadratic Programming,ting these signal-dependent distributions. The method is based on an evolutionary spectrum formulation of positive 11-Ds. The minimization problem reduces to a linearly-constrained quadratic programming problem, for which standard solutions are widely available.

Joint Distributions of Arbitrary Variables Made Easy,the theory of joint distributions of arbitrary variables into an easy exercise of coordinate transformation. While straightforward, the method can generate many distributions previously attainable only by the general construction of Cohen, including distributions of time versus inverse frequency, ti

The Analysis of Under Water Vehicle Non-Stationary Acoustic Transient Signals Using a New Fast Algosient signals are receiving considerable attention, especially from the standpoint of detection and tracking of under water vehicles. Thus, modern methods for processing these non-stationary acoustic transient signals are required. This paper presents a very powerful method for analyzing acoustic tr
