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 ...

Language and Mathematics [PDF]

, 2005
This collection of papers on Language and Mathematics presented in Working Group 8 at CERME 4 demonstrates some of the complexity of the field and the multiplicity of theoretical approaches taken by researchers. Perhaps we should expect this to be the

The e-multiplicity and addition-deletion theorems for multiarrangements [PDF]

, 2006
The addition-deletion theorems for hyperplane arrangements, which were originally shown in [T1], provide useful ways to construct examples of free arrangements. In this article, we prove addition-deletion theorems for multiarrangements.

Comparative Meta-Analysis of Arbitrage Opportunities in Option Pricing Models: Evidence from Black-Scholes, Heston, and Binomial Models [PDF]

Pizhūhish/hā-yi ḥisābdārī-i mālī
The purpose of this study is to empirically investigate arbitrage based on option pricing models, which uses three pricing methods, including Black-Scholes, Heston, and binomial. This study is an applied analysis with a meta-analysis method in nature. By

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.

Literature in the age of mathematics: Gender and the multiplicity of modernity [PDF]

, 2011
This dissertation investigates mathematics as a multivalent metaphor in twentieth-century fiction and theory and as a powerful cultural force integral to the development of competing modernist paradigms. Though it appears that writers such as Ezra Pound,

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 ...

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.
