Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Estimation for the Nonlinear Functional Relationship
The Annals of Statistics, 1988 Let \(\{b_ n\}^{\infty}_{n=1}\) and \(\{a_ n\}^{\infty}_{n=1}\) be sequences of positive real numbers such that \(a_ n\cdot b_ n=n\). Let \[ f(z^ 0_ t,\beta^ 0)=0,\quad t=1,2,...,b_ n \] be a functional relationship, where \(z^ 0_ t\) are unobservable fixed vectors belonging to a parameter space \(\Gamma \subset R^ p\), \(\beta^ 0\in \Omega \subset R ...

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.

Tikhonov Regularized Variable Projection Algorithms for Separable Nonlinear Least Squares Problems
Complexity, 2019 This paper considers the classical separable nonlinear least squares problem. Such problems can be expressed as a linear combination of nonlinear functions, and both linear and nonlinear parameters are to be estimated.

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 ...
