Bone microstructure and atomic periodic disharmonization in osteoporosis
Universa Medicina, 2015 Background Both cortical and cancellous bone display a complex, porous microstructure whose properties depend on the macrostructure of bone as well as age and health of the individual.

Laser Interference Lithography—A Method for the Fabrication of Controlled Periodic Structures
Nanomaterials, 2023 A microstructure determines macro functionality. A controlled periodic structure gives the surface specific functions such as controlled structural color, wettability, anti-icing/frosting, friction reduction, and hardness enhancement.

Periodic Microstructures Fabricated by Laser Interference with Subsequent Etching [PDF]
Nanomaterials, 2020 Periodic nanostructures have wide applications in micro-optics, bionics, and optoelectronics. Here, a laser interference with subsequent etching technology is proposed to fabricate uniform periodic nanostructures with controllable morphologies and smooth surfaces on hard materials. One-dimensional microgratings with controllable periods (1, 2, and 3 μm)

Design of Fault Detection Filters for Periodic Systems [PDF]
, 2004 We propose a numerically reliable computational approach to design fault detection filters for periodic systems. This approach is based on a new numerically stable algorithm to compute least order annihilators without explicitly building time-invariant ...

Magnetoactive elastomers with periodic and random microstructures
International Journal of Solids and Structures, 2014 AbstractWe investigate the behavior of magnetoactive elastomers (MAEs) with periodic and random distributions of circular and elliptical fibers. For the MAEs with periodic microstructures, we develop finite element models and determine the local fields as well as the effective properties of MAEs with rectangular and quasi-hexagonal unit cells.

Computational Methods for Periodic Systems - An Overview [PDF]
, 2001 We present an up-to-date survey of numerical methods for the analysis and design of linear discrete-time periodic systems. The basic tool is the periodic Schur form and its variants, for which a certain form of numerical stability can be ...
