Methods of Noise Suppression

Spence and Noronha [227] use the same set of equations discussed in Section 3.4.2.1 for the detection of progressive increase in heat evolution, where the following conditions must be met (1) the rate of temperature rise must be increasing, and (2) the rate of change if the temperature difference between the cooling medium and the contents must be positive, that is, 

If both conditions are met in a cooled vessel, or if the first condition occurs in a noncooled vessel, the potential situations for a thermal runaway are present.

The rest of the book is dedicated to the above quoted methods of photodetector enhancement. It is divided into two parts. One of them analyzes different methods to optimize the photodetector input, i.e., to perform its optical improvement, while the other part is denoted to nonequihbrium methods of noise suppression.
