Advanced Engineering Materials, EarlyView.This study developed a two‐step laser‐based process for sustainable surface treatment of Ti–6Al–4 V components, combining laser polishing and direct laser interference patterning with ns and ps pulses. Key findings include significant roughness reduction, hierarchical patterning with ps pulses, and improved homogeneity. A cost function is developed for

On elliptic solutions of the quintic complex one-dimensional Ginzburg-Landau equation
, 2006 The Conte-Musette method has been modified for the search of only elliptic solutions to systems of differential equations. A key idea of this a priory restriction is to simplify calculations by means of the use of a few Laurent series solutions instead ...

Production of Metallic Foam Precursors Using Current‐Activated Pressure‐Assisted Densification
Advanced Engineering Materials, EarlyView.A powder compaction metallurgical method, known as current‐activated pressure‐assisted densification, is applied to enhance the compaction of metal foam precursors. This method improves precursor quality by achieving higher density, lower electrical resistivity, and more uniform pore nucleation in the resulting foams, reducing energy consumption and ...

Elliptic equations with discontinuous nonlinearities
Topological Methods in Nonlinear Analysis, 1993 The paper deals with the existence and nonexistence of positive solutions of nonlinear elliptic equations, with the nonlinear term discontinuous in the unknown function. The authors distinguish between 3 types of solutions. Topological methods -- specifically the degree theory -- are employed to obtain the existence of solutions, either in \(\mathbb{R}^

An extension of a theorem by M. I. Freidlin to good solutions to elliptic nondivergence equations
Le Matematiche, 1999 In the context of second order linear uniformly elliptic equations with measurable coefficients, a result of Freidlin [9], which deals with homogenization type properties for elliptic equations with smooth periodic coefficients, is extended to ...

R-matrix Quantization of the Elliptic Ruijsenaars--Schneider model
, 1997 It is shown that the classical L-operator algebra of the elliptic Ruijsenaars-Schneider model can be realized as a subalgebra of the algebra of functions on the cotangent bundle over the centrally extended current group in two dimensions.
