Advanced Engineering Materials, EarlyView.Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Complex Dynamics Effect on Distributions [PDF]
arXiv, 2009 In this study, Lagrangian and Hamiltonian systems, which are mathematical models of mechanical systems, were introduced on the horizontal and the vertical distributions of tangent and cotangent bundles. Finally, some geometrical and physical results related to Lagrangian and Hamiltonian dynamical systems were deduced.

Advanced Engineering Materials, EarlyView.This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,

A Note on Positive Distributions in Gaussian Analysis [PDF]
Ukrainian Mathematical Journal 47 No. 5 1995, 2002 We describe positive generalized functionals in Gaussian Analysis. We focus on distribution spaces larger than the space of Hida Distributions. It is shown that a positive distribution is represented by a measure with specific growth of its moments. Equivalently this may be replaced by an integrability condition.

Low‐Velocity Penetration Impact Behavior of Triply Periodic Minimal Surface Strut‐Based Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS)‐based lattices are gaining attention for their multifunctional properties in applications as aeronautics and automotive, which involve low‐velocity impact loading. This work evaluates the low‐velocity penetration impact behavior of five distinct TPMS architectures.

On a distribution in frequency probability theory corresponding to the Bose-Einstein distribution [PDF]
arXiv, 2006 The notion of density of a finite set is discussed. We proof a general theorem of set theory which refines Bose-Einstein distribution.
