Rieffel's Deformation Quantization and Isospectral Deformations [PDF]
International Journal of Theoretical Physics, 2001 We demonstrate the relation between the isospectral deformation and Rieffel's deformation quantization by the action of $\mathbb{R}^d$.

Classifying deformable and non-deformable video objects [PDF]
7th International Conference on Imaging for Crime Detection and Prevention (ICDP 2016), 2016 This paper presents a fully automated approach to classifying deformable and non-deformable moving objects in a video surveillance scene. We estimate an object's motion using Marzat optical-flow algorithm. We filter the motion vectors and attempt to find the transformation that represents the correct mapping between the two positions.

IMA Journal of Applied Mathematics, 2016 For materials science, diamond crystals are almost unrivaled for hardness and a range of other properties. Yet, when simply abstracting the carbon bonding structure as a geometric bar-and-joint periodic framework, it is far from rigid. We study the geometric deformations of this type of framework in arbitrary dimension d, with particular regard to the ...

Journal of Materials Research and Technology, 2023 The present work demonstrates a novel interpretation of the effect of well-known heat treatments of solutionizing (ST) and solutionizing plus aging (T6) along with a newly-developed direct aging (DA), on the microstructural evolution and corresponding ...

Quarterly of Applied Mathematics, 2019 Geometric variations of objects, which do not modify the object class, pose a major challenge for object recognition. These variations could be rigid as well as non-rigid transformations. In this paper, we design a framework for training deformable classifiers, where latent transformation variables are introduced, and a ...

The effect of rare earth elements on the work softening behavior of as-cast Mg-4Al-2Sn
Materials Research Express, 2020 This work explores the addition of 1% Rear Earth (RE) elements on the Mg–4Al–2Sn magnesium alloy, with an emphasis laid on the microstructural evolution during solidification and subsequent hot deformation behavior.

基于定点形变资料获取断裂浅层倾向和倾角的方法研究—以唐山台为例
Dizhen xuebao, 2018 本文利用唐山地震台1978—2016年跨断层定点形变资料探究唐山地震台所跨断层的浅层倾向和倾角。首先，对形变资料进行数字滤波处理，消除原始观测数据中的非构造信息；其次，对数据精度进行评价，得出1997—2016年滤波后的形变数据年累计残差普遍较小、精度较高；最后，采用精度较高的形变数据计算SE和NW两倾向不同倾角下基线与水准和的累计残差分布，进而获取断层的浅层倾向和倾角。结果显示，依据跨断层定点形变资料获得唐山地震台所跨断层的浅层倾向为SE，倾角为89°，该结果与前人探槽剖面中断层产状相一致 ...
