用于锦屏深地核天体物理研究的强流加速装置的设计与试验进展
深地实验室 强流加速装置 直接测量
<
2021/2/23
对揭示元素形成及天体起源具有重要作用的关键低能核反应由于反应截面较小，同时受宇生高能射线影响，在地面环境难以进行直接测量。在极低本底的深地环境中，利用强流离子加速器打靶，进一步提高关心核反应的发生率，就可在地球开展接近伽莫夫能区低能核反应截面直接测量。锦屏深地实验室（CJPL）具有优越的地理环境，可有效屏蔽宇生高能射线。依托CJPL的有利条件，中国原子能科学研究院正在开展核天体物理关注能区核反应直...

2015/6/2
In this article, we present an evaluation of the application of statistical shape models for automatic landmark generation from a
training set of deformable shapes and in particular, from a class of...
AUTOMATIC BUILDING RECONSTRUCTION FROM AERIAL IMAGES: A GENERIC BAYESIAN FRAMEWORK
Building Reconstruction Modeling
<
2015/6/1
A novel system for automatic building reconstruction from multiple aerial images is presented. Compared to previous works, this
approach uses a very generic modeling of buildings as polyhedral shapes...
