Deformable classifiers

open access: yesQuarterly 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 ...

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

open access: yesDizhen 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 ...

The effect of rare earth elements on the work softening behavior of as-cast Mg-4Al-2Sn

open access: yesMaterials 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.

Concurrent influence of geological parameters on the integrated nano-pore structure and discretized pore families of the petroliferous Cambay shale assessed through multivariate dependence measure

open access: yesFrontiers in Earth Science, 2023
Heterogeneous nanopore structure and distribution regulate the gas trapping, desorption kinetics, and diffusion in shale matrices. In shale, pores range from continuous micro- and mesopore size distributions, varying with organic (total organic matter ...

Unveiling the influence of dendrite characteristics on the slip/twinning activity and the strain hardening capacity of Mg-Sn-Li-Zn cast alloys

open access: yesJournal of Magnesium and Alloys, 2023
This work explores the correlation between the characteristics of the cast structure (dendrite growth pattern, dendrite morphology and macro-texture) and strain hardening capacity during high temperature deformation of Mg-5Sn-0.3Li-0 and 3Zn multi ...

Measurement and analysis of brain deformation during neurosurgery. [PDF]

open access: yes, 2003
Recent studies have shown that the surface of the brain is deformed by up to 20 mm after the skull is opened during neurosurgery, which could lead to substantial error in commercial image-guided surgery systems.

Researches on Application of GPS to Earthquake Monitoring and Prediction [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2007
The earliest researches on application of GPS to earthquake monitoring and prediction in China began in 1980s, and it was limited to learn some relative technology from other countries and do some test with a few of equipments.

'Windswept deformity'. [PDF]

open access: yesArchives of Disease in Childhood, 1983
We describe 8 children with 'windswept deformity'--a valgus deformity of 1 knee in association with a varus deformity of the other. The disease is a physeal osteochondrosis and conservative treatment with serial corrective plaster casts is as effective as corrective osteotomies.

On the cyclic hardening/softening behavior of a rare earth-containing magnesium alloy during strain-controlled fatigue

open access: yesJournal of Materials Research and Technology, 2022
The origin of cyclic hardening under low strain amplitude (with N = 25284 cycles to failure) followed by pseudo-plateau response under high strain amplitude (with N = 2671 cycles to failure) during fully reversal (R = −1) strain-controlled pull–push ...

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,
