Optical Aberrations and Wavefront
Türk Oftalmoloji Dergisi, 2014 The deviation of light to create normal retinal image in the optical system is called aberration. Aberrations are divided two subgroup: low-order aberrations (defocus: spherical and cylindrical refractive errors) and high-order aberrations (coma ...

Performance prediction and procurement in practice : assessing the suitability of commodity cluster components for wavefront codes [PDF]
, 2009 The cost of state-of-the-art supercomputing resources makes each individual purchase a length and expensive process. Often each candidate architecture will need to be benchmarked using a variety of tools to assess likely performance.

POLYCHRONOUS WAVEFRONT COMPUTATIONS [PDF]
International Journal of Bifurcation and Chaos, 2009 There is great interest in methods for computing that do not involve digital machines. Many computational paradigms were inspired by brain research, such as Boolean neuronal logic [McCulloch & Pitts, 1943], the perceptron [Rosenblatt, 1958], attractor neural networks [Hopfield, 1982] and cellular neural nets [Chua & Yang, 1988].

Analysis and Mathematical Physics, 2023 AbstractWe develop a notion of wavefront set aimed at characterizing in Fourier space the directions along which a distribution behaves or not as an element of a specific Besov space. Subsequently we prove an alternative, albeit equivalent characterization of such wavefront set using the language of pseudodifferential operators.
