Flexural Strength and Hardness of Filler-Reinforced PMMA Targeted for Denture Base Application
Materials, 2021 The aim of this work was to evaluate the flexural strength and surface hardness of heat-cured Polymethyl methacrylate (PMMA) modified by the addition of ZrO2 nanoparticles, TiO2 nanoparticles, and E-glass fibre at different wt.% concentrations. Specimens

The hardness of conditional independence testing and the generalised covariance measure [PDF]
Annals of Statistics, 2018 It is a common saying that testing for conditional independence, i.e., testing whether whether two random vectors $X$ and $Y$ are independent, given $Z$, is a hard statistical problem if $Z$ is a continuous random variable (or vector).

Transferability and Hardness of Supervised Classification Tasks [PDF]
IEEE International Conference on Computer Vision, 2019 We propose a novel approach for estimating the difficulty and transferability of supervised classification tasks. Unlike previous work, our approach is solution agnostic and does not require or assume trained models.

Hardness-Aware Deep Metric Learning [PDF]
Computer Vision and Pattern Recognition, 2019 This paper presents a hardness-aware deep metric learning (HDML) framework. Most previous deep metric learning methods employ the hard negative mining strategy to alleviate the lack of informative samples for training.

Polydisperse hard spheres at a hard wall [PDF]
The Journal of Chemical Physics, 2004 The structural properties of polydisperse hard spheres in the presence of a hard wall are investigated via Monte Carlo simulation and density functional theory (DFT). Attention is focused on the local density distribution ρ(σ,z), measuring the number density of particles of diameter σ at a distance z from the wall.

The Hall–Petch and inverse Hall–Petch relations and the hardness of nanocrystalline metals
Journal of Materials Science, 2019 We review some of the factors that influence the hardness of polycrystalline materials with grain sizes less than 1 µm. The fundamental physical mechanisms that govern the hardness of nanocrystalline materials are discussed.
