Phase Decomposition in Polymers

Annual Review of Physical Chemistry, 1992
The area of "polymer mixtures," or the so-called "polymer blends," has interested many scientists since the 1960s. This is evident by the develop­ ment of the Flory-Huggins equation ( 1), which is a mean-field description of the free energy of mixing of flexible polymers.

Phase decomposition

Interpretation, 2016
Abstract Any seismic trace can be decomposed into a 2D function of amplitude versus time and phase. We call this process phase decomposition, and the amplitude variation with time for a specific seismic phase is referred to as a phase component.

Gas Phase Decomposition by the Lindemann Mechanism

SIAM Journal on Applied Mathematics, 1991
Summary: Several mechanisms have been proposed to explain observed phenomenon in gas phase decompositions, yet few theoretical solutions exist. One set of simple mechanisms is proposed by Christiansen and Lindemann [\textit{K. J. Laidler}, Chemical Kinetics, McGraw-Hill, New York (1950), pp.

Extended phase map decompositions for unitaries

Mathematical Structures in Computer Science, 2013
We give a complete structural characterisation of the map implemented by the positive branch of a one-way pattern. Our approach is based on the phase map decomposition (de Beaudrap et al. 2006; de Beaudrap et al. 2008) and leads to some preliminary results on the connection between the column structure of a given unitary and the angles of measurements ...

BTEX decomposition by ozone in gaseous phase

Journal of Environmental Management, 2012
Environment management is turning its efforts to control the air pollution. Nowadays, gas phase contaminants coming from different sources are becoming into the main cause of serious human illness. Particularly, benzene, toluene, ethylbenzene and xylene (BTEX) are getting more and more attention from the scientific community due the high level of ...

On the phase decomposition of Bi2Sr2CaCu2O8

Solid State Ionics, 1997
One of the ways to increase pinning force in superconductors is to create small precipitates of secondary phases in the bulk matrix. The samples of superconductor Bi 2.18 Sr 3-x Ca x Cu 2 O 5 with different compositions have been decomposed according to the phase diagram of the BiO 1.5 -SrO-CaO-CuO system.

Phase transformation on hydroxyapatite decomposition

Ceramics International, 2013
Abstract The collapse of sintered hydroxyapatite (HA) has been attributed to HA decomposition; however, the detailed variations in microstructure are still unclear. Two phase transformation routes of HA decomposition during sintering were identified by transmission electron microscopy in this study.

Decomposition of? phase in?+? titanium alloy

Metal Science and Heat Treatment, 1975
The thermal effects during heating of quenched VT22 alloy were investigated. It was found that the ..cap alpha.. + ..beta.. reversible ..beta.. transformation temperature is 920 to 930/sup 0/C. It appears that the ..beta.. solid solution is heterogeneous in chemical composition and the residues contain only that portion corresponding in electrochemical

Implementation of the Principle Phase Decomposition Algorithm

IEEE Transactions on Geoscience and Remote Sensing, 2007
This paper outlines the implementation details and enhancements of a previously described new concept in blind seismic deconvolution that is referred to as principle phase decomposition (PPD). A requirement of the PPD algorithm is for the investigator to determine the seismogram's dominant frequency (DF) and corresponding principle phase components ...

Phase Transitions in the Dynamic Mode Decomposition Algorithm

2019 IEEE 8th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2019
We analyze the Dynamic Mode Decomposition (DMD) algorithm in the noisy data setting. Previous work has shown that DMD is a source separation algorithm in disguise, i.e., that it is capable of unmixing linearly mixed time series. In this work, we analyze the performance of DMD when the mixed time series are corrupted by noise.
