Coherence analysis: Methods, solutions and problems

, 2008
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A coherence function is a measure of the correlation of two signals and may be used as a measure for functional relationship between brain areas.

Sources for random arrays with structured complex degree of coherence

, 2018
Simultaneous control of the far-field spectral density distribution, together with the modulus and the phase of the complex degree of coherence of a beam radiated by a stationary source, is hard to achieve in view of the intrinsic constraints on the ...

Student-perceived program coherence in seven disciplines: associations with student motivation and identification

Frontiers in Education
IntroductionProgram coherence is considered a critical factor for student learning and professional development in higher education. In teacher education, the subjective perception of coherence—defined as the degree to which learning opportunities and ...

Intrinsic degree of coherence of classical and quantum states

, 2017
In the context of the 2-dimensional (2D) polarization states of light, the degree of polarization P2 is equal to the maximum value of the degree of coherence over all possible bases.

Electromagnetic Coherence and Pancharatnam-Berry Phase in Young’s Interference Experiment

, 2007
The spectral interference law is used to derive the electromagnetic degree of coherence and the Pancharatnam-Berry phase in Young's two-pinhole setup. The phase has a straightforward connection to the Stokes parameters at the openings.

High-sensitivity detection of narrowband light in a more intense broadband background using coherence interferogram phase

, 2006
This paper describes an optical interferometric detection technique,. known as the interferogram phase step shift, which detects narrowband, coherent, and partially coherent light in more intense broadband incoherent background light using changes in the

Degree of higher-order optical coherence

, 1967
In this paper we define the normalized coherence function of arbitrary order (m, n), in a manner which seems to be a natural generalization of that defined for the second-order coherence function.

Climate policy integration, coherence and governance

, 2009
It is becoming evident that if high-consumption societies are to tackle climate change, significant changes in production processes as well as in consumption patterns will be required.

A statistical technique for measuring synchronism between cortical regions in the EEG during rhythmic stimulation [PDF]

, 2001
The coherence function has been widely applied in quantifying the degree of synchronism between electroencephalogram (EEG) signals obtained from different brain regions.
