Nonlinear control for collision-free navigation of UAV fleet
Sliding mode control Collision free navigation UAV coordination
2024/1/23
This paper presents the development of a cooperation scheme among unmanned aerial vehicle (UAV). Sliding mode control technique is used to guarantee that the set of robots can follow a reference traje...
LHCb begins using unique approach to process collision data in real-time（图）
LHCb 碰撞数据 大型强子对撞机
2023/5/29
Current technology does not allow all Large Hadron Collider (LHC) proton–proton collision data to be stored and analysed. It is therefore necessary to filter out the data according to the scientific g...
Yen-Jie Lee probes particle collision data for clues to the universe’s origins（图）
粒子碰撞数据 宇宙起源 粒子物理学
2023/6/9
When Yen-Jie Lee came to MIT as a graduate student in 2006, it was a bit of a culture shock. The aspiring particle physicist had studied physics at National Taiwan University before his career took a ...
Birth of magnetar from colossal collision potentially spotted for first time（图）
Birth of magnetar colossal collision potentially spotted first time
2020/11/20
Long ago and far across the universe, an enormous burst of gamma rays unleashed more energy in a half-second than the sun will produce over its entire 10-billion-year lifetime.After examining the incr...

locust swarms improve collision avoidance
2020/8/27
Plagues of locusts fly across the sky to attack crops, but the individual insects do not collide with each other in these massive swarms.Now a U.S. National Science Foundation-funded team of rese...
Astronomers find a golden glow from a distant stellar collision（图）
Astronomers golden glow distant stellar collision
2019/11/15
An NSF-supported team of astronomers found new evidence of the occurrence of a kilonova -- a cosmic explosion that creates massive amounts of gold and platinum -- that went unnoticed during initial ob...

The Art of Guessing in Combined Side-Channel Collision Attacks
MDCCF distinguisher voting collision voting
2019/6/13
Recent combined collision attacks have shown promising results for exploiting side-channel leakage information from both divide-and-conquer and analytical distinguishers. However, divide-and-conquer d...
On the Complexity of Collision Resistant Hash Functions: New and Old Black-Box Separations
Collision Resistance Statistical Zero Knowledge Black box separations
2019/6/12
The complexity of collision-resistant hash functions has been long studied in the theory of cryptography. While we often think about them as a Minicrypt primitive, black-box separations demonstrate th...
New Semi-Free-Start Collision Attack Framework for Reduced RIPEMD-160
hash function RIPEMD-160 freedom degree utilization
2019/6/10
RIPEMD-160 is a hash function published in 1996, which shares similarities with other hash functions designed in this time-period like MD4, MD5 and SHA-1. However, for RIPEMD-160, no (semi-free-start)...

Collision-detecting suitcase wayfinding app blind navigate airports
2019/10/30
Researchers at Carnegie Mellon University say that a wayfinding smartphone app and a smart suitcase that warns blind users of impending collisions can help people with visual disabilities navigate air...
An Efficient and Compact Reformulation of NIST Collision Estimate Test
IID Non-IID Min Entropy
2019/5/14
In this paper we give an efficient and compact reformulation of NIST collision estimate test given in SP-800 90B. We correct an error in the formulation of the test and show that the test statistic ca...

Tectonic collision 50 million years ago widespread ocean changes
2019/11/22
When the landmass that today is the Indian subcontinent slammed into Asia some 50 million years ago, the collision changed the configuration of the continents and altered global climate.Now a team of ...
Horizontal Collision Correlation Attack on Elliptic Curves
side-channel analysis elliptic curves implementations ECDSA
2019/4/1
Elliptic curves based algorithms are nowadays widely spread among embedded systems. They indeed have the double advantage of providing efficient implementations with short certi cates and of being rel...
