Shape-independent hardness estimation using deep learning and a GelSight tactile sensor [PDF]
IEEE International Conference on Robotics and Automation, 2017 Hardness is among the most important attributes of an object that humans learn about through touch. However, approaches for robots to estimate hardness are limited, due to the lack of information provided by current tactile sensors.

Hard Negative Examples are Hard, but Useful [PDF]
, 2020 Triplet loss is an extremely common approach to distance metric learning. Representations of images from the same class are optimized to be mapped closer together in an embedding space than representations of images from different classes. Much work on triplet losses focuses on selecting the most useful triplets of images to consider, with strategies ...

Frustration of freezing in a two dimensional hard-core fluid due to particle shape anisotropy [PDF]
Condens. Matter Phys., 2016, vol. 19, No. 2, 23605, 2016 The freezing mechanism suggested for a fluid composed of hard disks [Huerta et al., Phys. Rev. E, 2006, 74, 061106] is used here to probe the fluid-to-solid transition in a hard-dumbbell fluid composed of overlapping hard disks with a variable length between disk centers.

Influence of heat treatment on the wear resistance of the ZnAl40Cu1.5Ti1.5 alloy
Archives of Metallurgy and Materials, 2017 Zn-Al-Cu alloys are predominantly used due to their tribological properties. One of the crucial issues related to the use of Zn-Al alloys is their dimensional instability.
