Accelerating ptychographic reconstructions using spectral initializations [PDF]
Optics Letters, 2021 Ptychography is a promising phase retrieval technique for label-free quantitative phase imaging. Recent advances in phase retrieval algorithms witnessed the development of spectral methods to accelerate gradient descent algorithms. Using spectral initializations on experimental data, for the first time, we report three times faster ptychographic ...

Accelerated spectral approximation [PDF]
Mathematics of Computation, 1998 A systematic development of higher order spectral analysis, introduced by Dellwo and Friedman, is undertaken in the framework of an appropriate product space. Accelerated analogues of Osborn’s results about spectral approximation are presented. Numerical examples are given by considering an integral operator.

Probabilistic seismic hazard assessment of the historical peninsula of Istanbul [PDF]
Natural Hazards and Earth System Sciences, 2012 In order to design buildings that are resistant to earthquakes, first it is necessary to determine the parameters of ground motion. In this study, the earthquake seismic hazard analysis of the Old City Districts of Istanbul (Fatih and Eminonu) was ...

Accelerated spectral refinement Part I: simple eigenvalue [PDF]
The Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 2000 AbstractA general framework is developed for constructing higher order spectral refinement schemes for a simple eigenvalue. Well-known techniques for ordinary spectral refinement are carried over to higher order spectral refinement yielding faster rates of convergence. Numerical examples are given by considering an integral operator.

Buildings, 2023 There are very few results in the literature on spectral content of seismic ground displacement; nonetheless, these results are singular as most of the spectral content is limited to a very narrow low frequency band, contrary to ground acceleration ...

Accelerated spectral refinement Part II: Cluster of eigenvalues [PDF]
The ANZIAM Journal, 2000 AbstractThe framework for accelerated spectral refinement for a simple eigenvalue developed in Part I of this paper is employed to treat the general case of a cluster of eigenvalues whose total algebraic multiplicity is finite. Numerical examples concerning the largest and the second largest multiple eigenvalues of an integral operator are given.
