A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Some Notes about Inference for the Lognormal Diffusion Process with Exogenous Factors

Mathematics, 2018
Different versions of the lognormal diffusion process with exogenous factors have been used in recent years to model and study the behavior of phenomena following a given growth curve.

The Distribution of the Domination Number of a Family of Random Interval Catch Digraphs [PDF]

, 2010
We study a new kind of proximity graphs called proportional-edge proximity catch digraphs (PCDs)in a randomized setting. PCDs are a special kind of random catch digraphs that have been developed recently and have applications in statistical pattern ...

Rosenblatt distribution subordinated to gaussian random fields with long-range dependence [PDF]

, 2016
The Karhunen-Lo\`eve expansion and the Fredholm determinant formula are used to derive an asymptotic Rosenblatt-type distribution of a sequence of integrals of quadratic functions of Gaussian stationary random fields on R^d displaying long-range ...

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Pseudorandom functions whose asymptotic distributions are asymptotically gaussian

Journal of Mathematical Analysis and Applications, 1991
Given an ergodic transformation T on the Lebesgue space ([0,1],dx) and a continuous function h(x) \((\int^{1}_{0}h(x)dx=0)\), we are interested in asymptotic behaviours of the pseudorandom functions, \(q_{\theta}(t;x)=\sqrt{\theta}\cdot h(T^{[\theta t]}x)\) (x\(\in (0,1)\), \(\theta >0)\).

Asymptotic Distribution of Symmetric Statistics

The Annals of Statistics, 1980
Sequences of $m$th order symmetric statistics are examined for convergence in law. Under appropriate conditions, a limiting distribution exists and is equivalent to that of a linear combination of products of Hermite polynomials of independent $N(0, 1)$ random variables. Connections with the work of von Mises, Hoeffding, and Filippova are noted.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Testing Homogeneity for Poisson Processes Prueba de homogeneidad para procesos de Poisson

Revista Colombiana de Estadística, 2011
We developed an asymptotically optimal hypothesis test concerning the homogeneity of a Poisson process over various subintervals. Under the null hypothesis, maximum likelihood estimators for the values of the intensity function on the subintervals are ...

The accuracy of merging approximation in generalized St. Petersburg games

, 2009
Merging asymptotic expansions of arbitrary length are established for the distribution functions and for the probabilities of suitably centered and normalized cumulative winnings in a full sequence of generalized St. Petersburg games, extending the short
