In an effort to face this challenge, the Differential Absolute Contrast (DAC) method was proposed as a solution to the problem of a priori selection of a sound area; it is based on the 1D model of adiabatic heat transfer over the surface of a solid semi-infinite material without internal flaws, heated by a thermal pulse. The technique pretends to predict the temperature in every sound point of the excited surface to subtract these predicted values from sensed real temperatures, and obtain greater discrepancies from defective regions than from sound areas (Benitez, 2007).
This then leads to a thermal pulse during which the star expands and brightens for a short period of time.
There is a thermal pulse, a pressure wave or blast wind, and shrapnel.
The shell originates from a thermal pulse during which the star had a brief period of increased mass loss.
Every 10,000 to 50,000 years, these gaseous behemoths burn helium for a few hundred years in a runaway process known as a thermal pulse, causing the layers of the star to mix.
As for the gas, reporting to a slice that gets the thermal pulse in the heat exchange, the specific volume of the gas will be heated (increasing its temperature) and then slowly it will cool down (decreasing its temperature), like shown in the next figure:

The sensing process starts with a thermal pulse created in the oil layer by the absorption of a powerful C[O.sub.2] laser pulse.
The mission team quickly reported that it had acquired useful data and that the Lunar Reconnaissance Orbiter had picked up the impact's thermal pulse. But these notes of success were drowned out in a chorus of groans that turned to mocking laughter.
The brief but intense thermal pulse of a nuclear explosion immediately ignites any combustible material nearby.
Two bright Miras, R Aquilae and R Hydrae, were long known to have changing periods, which were eventually attributed to thermal pulses. The question then became whether we could catch a star just starting a thermal pulse.
These three terms can be regarded as three consecutive ground thermal pulses q, [q.sub.y], [q.sub.h] and [q.sub.h] each multiplied by their respective effective ground thermal resistance [R.sub.y], [R.sub.m], and [R.sub.h].
