Quantitative Phase Analysis [PDF]
, 2012 The most common use of powder diffraction in analytical science is the identification of crystalline components, or phases, present in a sample of interest. The near universal applicability of the method for this purpose is derived from the fact that a diffraction pattern is produced directly from the components’ crystal structure.

The Stationary Phase Approximation, Time-Frequency Decomposition and Auditory Processing [PDF]
, 2012 The principle of stationary phase (PSP) is re-examined in the context of linear time-frequency (TF) decomposition using Gaussian, gammatone and gammachirp filters at uniform, logarithmic and cochlear spacings in frequency. This necessitates consideration

Cyclic variations of quality characteristics in river water in an industrial region
Water Science and Technology, 2021 River water in industrial regions is a dynamic medium defined by random variables that cannot be described by linear equations. However, some water quality characteristics, e.g., pollutant concentrations, which look chaotically distributed are largely ...

Sequence Phase Analysis of Phased Rectifier
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2013 At present, three-phase bridge type full controlled is the most widely applied in all kinds of rectifier circuit. To guarantee the normal work of the phase control circuit, it is the most important thing that should be according to the size of the triggering angle at the right moment to the thyristor trigger of the circuit on effective puls.

Shuttle instabilities: semiclassical phase analysis
, 2004 We present a semiclassical analysis of the instability of an electron shuttle composed of three quantum dots: two are fixed and coupled via leads to electron resevoirs at different chemical potentials, while the central dot is mounted on a classical ...

The Electroweak Phase Transition: A Non-Perturbative Analysis [PDF]
, 1995 We study on the lattice the 3d SU(2)+Higgs model, which is an effective theory of a large class of 4d high temperature gauge theories. Using the exact constant physics curve, continuum ($V\to\infty, a\to 0$) results for the properties of the phase ...
