Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Asymptotics of Entropy of the Dirichlet-Multinomial Distribution
2019 IEEE International Symposium on Information Theory (ISIT), 2019 Dirichlet distribution and multinomial distribution play important role in information theory and statistics. They find applications in estimation, average minimax redundancy in source coding, Polya urn model, and graph compression. Dirichlet-multinomial distribution is a multinomial distribution in which parameters are distributed according to the ...

New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design
Advanced Engineering Materials, EarlyView.This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...

Two Characterizations of the Dirichlet Distribution
The Annals of Statistics, 1973 Let $X = (X_1, \cdots, X_k)$ be a random vector with all $X_i \geqq 0$ and $\sum X_i \leqq 1$. Let $k \geqq 2$, and suppose that none of the $X_i$, nor $1 - \sum X_i$ vanishes almost surely. Without any further regularity assumptions, each of two conditions is shown to be necessary and sufficient for $X$ to be distributed according to a Dirichlet ...

A Continuous Analog of Correspondence Analysis with an Application to the Dirichlet Distribution [PDF]
The Egyptian Statistical Journal, 1993 In this article we intend to combine the well developed factorial analysis of continuous correspondence theory with Dirichlet distribution. It is pointed out that the hypergeometric function is capable of characterizing the factors playing the major role

Advanced Functional Materials, EarlyView.HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.
