Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

The expected number of critical percolation clusters intersecting a line segment [PDF]

, 2015
We study critical percolation on a regular planar lattice. Let EG(n) be the expected number of open clusters intersecting or hitting the line segment [0; n].

MATHEMATICAL MODEL OF COLORIMETRY

Bulletin of Kyiv Polytechnic Institute. Series Instrument Making, 2017
Робота присвячена аналізу методів математичного моделювання і вивчення процесу розпізнавання людиною кольорових відбитків та побудови пристроїв для класифікації предметів за їх колірним характеристикам. Розглядається конструкція датчиків кольору, в яких використовується не три, а більша кількість фотоприймачів, що дає можливість шляхом систематичних ...

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Mathematical modeling and analysis of thermal dynamics in an electrical contact bridge with nonlinear Stefan problem including thermoelectric effect and internal heat source

Results in Applied Mathematics
This paper presents a mathematical model and analytical study of the thermal dynamics in an electrical contact bridge under the influence of the Thomson effect and Joule heat generation. The model considers a bridge structure adjacent to a vapor zone, in

On the structure of λ-Cantor set with overlaps

, 2019
Given λ∈(0,1), let Eλ be the self-similar set generated by the iterated function system (IFS) {x/3,(x+λ)/3,(x+2)/3}. Then Eλ is a self-similar set with overlaps.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

The Role of a Two-Phase Region in Directional Crystallization of Binary Liquids

Mathematics
Motivated by the widespread occurrence of directional crystallization in nature, laboratory experiments and industrial facilities, we consider how a two-phase (mushy) region filled simultaneously with liquid and solid material influences the process and ...

Dimensionality Reduction and Uncertainty Quantification for Inverse Problems

, 2015
Many inverse problems in science and engineering involve multi-experiment data and thus require a large number of forward simulations. Dimensionality reduction techniques aim at reducing the number of forward solves by (randomly) subsampling the data. In

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
