1995 Frank Nelson Cole Prize in Algebra

The Frank Nelson Cole Prize in Algebra is awarded every five years for a notable research memoir in algebra which has appeared in the previous five years. This prize and the Frank Nelson Cole Prize in Number Theory were established in honor of Professor Frank Nelson Cole, who served as secretary of the AMS from 1896 to 1920 and also served as editor-in-chief of the Bulletin for twenty-one years...

Numerical extraction of Cole-Cole impedance parameters from step response

In this paper we propose a numerical method to extract the four parameters (Ro, R∞, C, and α) that characterize a single-dispersion Cole-Cole impedance model from its step response, based on modelling the step response using fractional calculus, without requiring direct measurement of the real and imaginary impedance parts. MATLAB simulations using Cole-Cole impedances of fruit tissues with α <...

RATING AGENCIES Harold Cole

For decades credit rating agencies were viewed as trusted arbiters of creditworthiness and their ratings as important tools for managing risk. The common narrative is that the value of ratings was compromised by the evolution of the industry to a form where issuers pay for ratings. In this paper we show how credit ratings have value in equilibrium and how reputation insures that, in equilibrium...
