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.

Randomized Sparse Block Kaczmarz as Randomized Dual Block-Coordinate Descent
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 We show that the Sparse Kaczmarz method is a particular instance of the coordinate gradient method applied to an unconstrained dual problem corresponding to a regularized ℓ1-minimization problem subject to linear constraints.

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 ...

De l’événement au problème. Archéologie d’un paradigme mathématique [PDF]
La Deleuziana, 2020 The article deals with the presence in Deleuze of an image of mathematical thought centered on the idea of problem. This vision of mathematics, which Emile Bréhier’s studies trace back to the Stoic and Neoplatonic philosophies, feeds romantic thought as ...

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.

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 ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure
Advanced Engineering Materials, EarlyView.Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

PEMBELAJARAN MATEMATIKA DENGAN MODEL SAVI BERORIENTASI PAKEM
Ta'dib, 2016 Several international surveys and national examinations show that learning Mathematics in Indonesia have not expected optimum result. This is not only indicated by students’ low test score only but also by their low interest and negative image on the ...
