Comparative Study of Cosine–Histogram Association and Deep Learning Methods for Leather Defect Detection

open access: yesIEEE Access
Reliable leather defect detection is essential for industrial quality control, yet many deep learning solutions demand substantial computational resources and extensive training.

Fast computation by block permanents of cumulative distribution functions of order statistics from several populations

open access: yes, 2007
The joint cumulative distribution function for order statistics arising from several different populations is given in terms of the distribution function of the populations.

Multilinear formulas and skepticism of quantum computing

open access: yesProceedings of the thirty-sixth annual ACM symposium on Theory of computing, 2004
Several researchers, including Leonid Levin, Gerard 't Hooft, and Stephen Wolfram, have argued that quantum mechanics will break down before the factoring of large numbers becomes possible. If this is true, then there should be a natural set of quantum states that can account for all experiments performed to date, but not for Shor's factoring algorithm.

Asymptotic unbounded root loci - Formulae and computation [PDF]

open access: yes1981 20th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1981
We study the asymptotic behavior of the dosed loop eigenvalues (root loci) of a strictly proper linear time-invariant control system as loop gain goes to \infty . The formulas are stated in terms of the eigenvalues of nested restricted linear maps of the form A(\mod S_{2})|_{S_{1}} where S 1 and S 2 are subspaces of complementary dimension.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Black Holes and Complexity via Constructible Universe

open access: yesUniverse, 2020
The relation of randomness and classical algorithmic computational complexity is a vast and deep subject by itself. However, already, 1-randomness sequences call for quantum mechanics in their realization.

Cubic scaling algorithms for RPA correlation using interpolative separable density fitting

open access: yes, 2017
We present a new cubic scaling algorithm for the calculation of the RPA correlation energy. Our scheme splits up the dependence between the occupied and virtual orbitals in $\chi^0$ by use of Cauchy's integral formula.

Computing the Density of States of Boolean Formulas [PDF]

open access: yes, 2010
In this paper we consider the problem of computing the density of states of a Boolean formula in CNF, a generalization of both MAX-SAT and model counting. Given a Boolean formula F, its density of states counts the number of configurations that violate exactly E clauses, for all values of E.

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Multifidelity Comparison of Supersonic Wave Drag Prediction Methods Using Axisymmetric Bodies

open access: yesAerospace
Low-fidelity analytic and computational wave drag prediction methods assume linear aerodynamics and small perturbations to the flow. Hence, these methods are typically accurate for only very slender geometries.
