Petro earns Air Force award to research next-gen spacecraft propellants（图）
佩特罗因 下一代 航天器 推进剂
2023/5/18
With the advancement of satellite propulsion systems will come a new age in space exploration, which is why the Air Force Office of Scientific Research has selected Elaine Petro, assistant professor o...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：An active contour model with local variance force term and its efficient minimization solver for multi-phase image
局部方差力项 活动轮廓模型 多相图像 最小化求解器
2023/5/8
In this work, we propose an active contour model with a local variance force (LVF) term that can be applied to multi-phase image segmentation problems. With the LVF, the proposed model is very effecti...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Dynamics near a shear flow with Coriolis force
科里奥利力 剪切流 动力学
2023/5/16
In this talk, I will discuss the dynamics near a shear flow when the Coriolis force is involved. Compared with the non-Coriolis case, the spectral properties of the linearized Euler operator change fu...
Tool use has long been a hallmark of human intelligence, as well as a practical problem to solve for a vast array of robotic applications. But machines are still wonky at exerting just the right amoun...
In the Standard Model of particle physics, the Brout–Englert–Higgs mechanism provides mass to elementary particles. While physicists are carrying out direct studies of the Higgs boson to test this mec...

近日，中国地质大学机电学院葛明峰副教授团队硕士研究生徐景喆以第一作者在工业电子领域顶尖期刊《IEEE Transactions on Industrial Electronics》（IF= 7.515）上刊发研究成果。该文首先构建了一种新型半自主网络化从机器人的遥操作控制系统，并提出了力反馈分层控制框架解决了该系统的同步及编队跟踪问题。
Freestyle, a randomized version of ChaCha for resisting offline brute-force and dictionary attacks
Brute-force resistant ciphers Dictionary based attacks Key-guessing penalty
2018/11/29
This paper introduces Freestyle, a randomized, and variable round version of the ChaCha cipher. Freestyle demonstrates the concept of hash based halting condition, where a decryption attempt with an i...
Improved Brute-Force Search Strategies for Single-Trace and Few-Traces Template Attacks on the DES Round Keys
DES TDES Template Attack
2018/11/7
We present an improved search strategy for a template attack on the secret DES key of a widely-used smart card, which is based on a Common-Criteria certified chip. We use the logarithm of the probabil...
