Multi-Risk-RRT: An Efficient Motion Planning Algorithm for Robotic Autonomous Luggage Trolley Collection at Airports
Zhirui Sun, Boshu Lei, Peijia Xie +4
Robots have become increasingly prevalent in dynamic and crowded environments such as airports and shopping malls. In these scenarios, the critical challenges for robot navigation…
A Robust ADMM-Based Optimization Algorithm For Underwater Acoustic Channel Estimation
Tian Tian, Agastya Raj, Bruno Missi Xavier +3
Accurate estimation of the Underwater acoustic (UWA) is a key part of underwater communications, especially for coherent systems. The severe multipath effects and large delay sprea…
The Emerging Weak Antilocalization Effect in Semimetal TaNbSb Single Crystal
Lei Guo, Meng Xu, Lei Chen +5
Weak antilocalization (WAL) effect is commonly observed in 2D systems, or 3D topological insulators, topological semimetal systems. Here we report the clear sign of WAL effect in h…
Coexistence of Logarithmic and SdH Quantum Oscillations in Ferromagnetic Cr-doped Tellurium Single Crystals
Shu-Juan Zhang, Lei Chen, Shuang-Shuang Li +9
We report the synthesis of transition-metal-doped ferromagnetic elemental single-crystal semiconductors with quantum oscillations using the physical vapor transport method. The 7.7…
Limits of Predictability in Top-N Recommendation
En Xu, Zhiwen Yu, Ying Zhang +2
Top-N recommendation aims to recommend each consumer a small set of N items from a large collection of items, and its accuracy is one of the most common indexes to evaluate the per…
Disco Intelligent Reflecting Surfaces: Active Channel Aging for Fully-Passive Jamming Attacks
Huan Huang, Ying Zhang, Hongliang Zhang +3
Due to the open communications environment in wireless channels, wireless networks are vulnerable to jamming attacks. However, existing approaches for jamming rely on knowledge of…
Illegal Intelligent Reflecting Surface Based Active Channel Aging: When Jammer Can Attack Without Power and CSI
Huan Huang, Ying Zhang, Hongliang Zhang +2
Illegal intelligent reflecting surfaces (I-IRSs), i.e., the illegal deployment and utilization of IRSs, impose serious harmful impacts on wireless networks. The existing I-IRS-base…
Bi-AM-RRT*: A Fast and Efficient Sampling-Based Motion Planning Algorithm in Dynamic Environments
Ying Zhang, Heyong Wang, Maoliang Yin +2
The efficiency of sampling-based motion planning brings wide application in autonomous mobile robots. The conventional rapidly exploring random tree (RRT) algorithm and its variant…
