• #### Quartz Enhanced Photoacoustic Spectroscopy Based Trace Gas Sensors Using Different Quartz Tuning Forks ﻿

(2015)
A sensitive trace gas sensor platform based on quartz-enhanced photoacoustic spectroscopy (QEPAS) is reported. A 1.395 μm continuous wave (CW), distributed feedback pigtailed diode laser was used as the excitation source ...
• #### Quartz-enhanced photoacoustic spectroscopy ﻿

(2007-07-17)
Methods and apparatus for detecting photoacoustic signals in fluid media are described. The present invention differs from conventional photoacoustic spectroscopy in that rather than accumulating the absorbed energy in the ...
• #### Quartz-Enhanced Photoacoustic Spectroscopy: A Review ﻿

(2014)
A detailed review on the development of quartz-enhanced photoacoustic sensors (QEPAS) for the sensitive and selective quantification of molecular trace gas species with resolved spectroscopic features is reported. The basis ...

• #### Quasi-Circular Rotation Invariance in Image Denoising ﻿

(1999-10-20)
This paper studies a new method for wavelet-based image denoising which is translation invariant (TI) <b>and</b> rotation invariant (RI). These invariances are crucial in image denoising and, more generally, may play ...
• #### Quasi-elastic resonant x-ray scattering ﻿

(1997)
In the fast collision approximation, the scattering amplitude operator of the quasi-elastic scattering is expressed as the summation of multipole moment operators $M\sp{(k)}(l\sb{i},s\sb{i})$ of the valence shell involved ...
• #### Quasi-static study on the fluid and structure interactions of the subsurface safety valves (SSSV) for extreme high pressure and high temperature (XHPHT) applications ﻿

(2010)
This thesis summarizes the preliminary design work of a new subsurface safety valve (SSSV) for extreme high pressure (30,000 psi) and high temperature (450&deg;F) (XHPHT) applications. Current SSSV designs are not reliable ...
• #### Quasiparticle coupled cluster theory for pairing interactions ﻿

(2014)
We present an extension of the pair coupled cluster doubles (p-CCD) method to quasiparticles and apply it to the attractive pairing Hamiltonian. Near the transition point where number symmetry gets spontaneously broken, ...
• #### Quasispecies theory for evolution of modularity ﻿

(2015)
Biological systems are modular, and this modularity evolves over time and in different environments. A number of observations have been made of increased modularity in biological systems under increased environmental ...

(1968)
• #### Quaternion Wavelets for Image Analysis and Processing ﻿

(2004-10-01)
Using the concepts of two-dimensional Hubert transform and analytic signal, we construct a new quaternion wavelet transform (QWT). The QWT forms a tight frame and can be efficiently computed using a-2-D dual-tree filter ...
