Geometric maximizers of Schatten norms of some convolution type integral operators [PDF]

, 2017
In this paper we prove that the ball is a maximizer of the Schatten $p$-norm of some convolution type integral operators with non-increasing kernels among all domains of a given measure in $\mathbb R^{d}$.

Meshfree Approach for the Torsional Analysis of Orthotropic and FGM Thin-Walled Open Sections [PDF]

Mechanics of Advanced Composite Structures
The torsional study of different engineering sections made up of orthotropic and functionally graded material is presented in this paper. Prandtl’s stress function approach is used for the formulation of governing differential equations.

Similar dissection of sets [PDF]

, 2010
In 1994, Martin Gardner stated a set of questions concerning the dissection of a square or an equilateral triangle in three similar parts. Meanwhile, Gardner's questions have been generalized and some of them are already solved.

Algorithmic Design of Disordered Networks With Arbitrary Coordination: Application to Biophotonics

Advanced Functional Materials, EarlyView.
Predictive Design of Disordered Networks: Disordered network‐like morphologies are abundant in nature, from cytoskeletal networks to bone structures and chalcogenide glasses. These structures are naturally hard to characterize. A new algorithmic tool extends the established Wooten–Weaire–Winer (WWW) algorithm to valencies above 4.

The flows structure in unsteady gas flow in pipes with different cross-sections

EPJ Web of Conferences, 2017
The results of numerical simulation and experimental study of the structure of unsteady flows in pipes with different cross sections are presented in the article. It is shown that the unsteady gas flow in a circular pipe is axisymmetric without secondary
