'Whenever you have a defect, you would have some influence in how this thermal wave
is penetrating the material,' explained Ferber.
When [tau] = 0, the thermal wave
model of bioheat transfer becomes Pennes bioheat transfer model.
In photopyroelectric (PPE) methods [1, 2], the thermal wave
cavity (TWC) technique has been extensively applied for measuring the thermal properties of various types of liquids .
In this case, the SC6000 camera (Flir systems) is used; for the purpose, the system is equipped with a Lock-in module that drives the halogen lamp to generate a harmonic thermal wave
of selectable frequency / and the IRLock-In[C] software.
Lock-In Thermography is based on the solution of the Fourier equation obtained taking into account the hypothesis that a homogeneous semi-infinite solid body is impinged by a sinusoidal thermal wave
of temperature T propagating along x direction with modulation frequency, [omega], and initial temperature, [T.sub.0],
The first 1D example is based on hyperbolic thermal wave
equations and is presented to demonstrate the ability of the proposed DGFEM to filter out the numerical oscillations in wave after, wave-front, and the interface between two layers.
In previous equations, NS is an arbitrary number of thermal wave
reflections to be considered (the smaller diffusivity, the higher NS value).
Effects of stiffness and thermal relaxation times on the amplitude ratios for incidence of various plane waves, for example, longitudinal wave (P-wave), thermal wave
(T-wave), and transverse wave (SV-wave), are depicted numerically and shown graphically with angle of incidence.
A 200mWCW DPSS (MGL 150(10)) modulated laser beam impinged on the black painted external face of the thin metal foil and converted it to a thermal wave
. The PVDF film was fixed with silicon glue to a Perspex substrate.

Among them are discussions of characteristics of laser-generated visco-elastic Rayleigh waves, selective optical gas sensors using butterfly wing scales nanostructures, fabricating a monolithic integrated bimaterial resonant uncooled infrared sensor, different kinds of carbon-based material for resistive gas sensing, direct surface relief formation in polymer films, using a microwave sensor as an online indicator of neurological impairment during surgical procedures, improving amorphous selenium photodetector performance using an organic semiconductor, and evaluating the polarization state of integrated piezoelectric sensors and actuators using the thermal wave
Since the efficiency of the basic adsorption refrigeration cycle is low, and the cooling output is not continuous, many advanced adsorption refrigeration cycles (such as the heat recovery cycle, mass recovery cycle, thermal wave
cycle, forced convective thermal wave
cycle, etc.) have been developed to improve efficiency and practicability.
