Many physical phenomena are described by first-order differential equations whose solution
is an exponential decay. Determining the time constants and amplitudes of exponential …

The application of quasi-elastic light scattering for the determination of particle size
distributions is reviewed. The basic principles and assumptions on which the method relies …

Particle characterization is an important component in product research and development,
manufacture, and quality control of particulate materials and an important tool in the frontier …

We describe the wavelet–vaguelette decomposition (WVD) of a linear inverse problem. It is
a substitute for the singular value decomposition (SVD) of an inverse problem, and it exists …

Publisher Summary This chapter considers linear inverse problems that have the following
general structure. The first step is the definition of the direct problem, which must be linear …

Thermal emission of current carriers from defects in semiconductors has been used as a
characterization technique for over 50 years. One of the most significant early publications …

Many algorithms for calculating concentration depth profiles (CDPs) from ARXPS or ARAES
measurements have been published over the last decade, ranging from simple least …

Transport properties of a thermal medium determine how its conserved charge densities (for
instance the electric charge, energy or momentum) evolve as a function of time and …

The authors discuss linear methods for the solution of linear inverse problems with discrete
data. Such problems occur frequently in instrumental science, eg tomography, radar, sonar …

Biological tissues frequently contain different water compartments, and these often have
distinct transverse relaxation times. Quantification of these may be problematic on clinical …
