The principle of coherence was successfully used to define a number of units of measure based on the centimetre gram second (CGS) system of units (CGS), including the erg for energy, the dyne for force, the barye for pressure, the poise for dynamic viscosity and the stokes for kinematic viscosity.
The latest generation technology is based on the principle of partial coherence interferometry, which uses a light source to make measurements [ 1, 4].
High-definition OCT (HD-OCT) is a recently introduced non-invasive technology based on the principle of low coherence interferometry [ 4– 9, 15].
The EU established the principle of Policy Coherence for Development in recognition that "some of its policies can have a significant impact outside of the EU and that either contributes to or undermines its development policy".
OCT makes it possible to examine high-resolution cross-sections of ocular tissues using the principle of low coherence interferometry [ 6, 7] and seems more reliable than SLP and HRT for the evaluation of the RNFL [ 8].
Both the principle of Policy Coherence for Development and Sustainability Impact Assessment tools are aligned with the objectives of global health impact assessments in that they all focus on considering the global, cross-border impacts of EU or UK policies and actions on developing countries – albeit on different sectors or priorities.
The operation of OCT is based on the principle of low coherence interferometry: the distances and sizes of different structures in the eye are determined by measuring the "echo" time it takes for light to be back-scattered from different structures at various axial distances.
Validity and cognitive import are matters calling for logical, semantic, epistemological, and metaphysical criteria of the principles of rational order and coherence, meaning, knowledge, and reality and this means that the appraisal of religious experience is ultimately a philosophical and theological problem.
The principles of sparseness and temporal coherence were originally formulated without explicit reference to the behavioral repertoire of the agent.
Optical coherence tomography (OCT) [ 26– 29] works based on the principle of low-coherence interferometry.
