Mathematica Users: I am now working on applications of Nonstationary Time Series Analysis to brain electrical signals by using standard packages of the Mathematica System. In this context, several difficulties around the subject of making decision about of signal depacture from stationarity have been arisen. Hence, I am using some approximating techniques like confidence intervals or boostrap for focusing this problem on. But unfortunately, I have not found a boundary of bias for both real and imaginary crosspectra. One of the most magisterial dissertation on this whole topic has been presented by Dr.G. Melard from Brussels Free University. I have been attempting to contact him but I dont have the exact address. I would appreciate very much any suggestion about how to save this troubles. Maybe someone could give me Dr. Melard's address, fax, telephone or Email numbers. Please if you are going to answer me you must do it by my Email number (invest at cneuro.cu). I am not user of Mathematica System. Thanks very much in advance. Jorge J. Riera Cuban Neuroscience Center
