Angle-Displacement Rigidity Theory with Application to Distributed Network Localization

no code implementations19 Dec 2023 Xu Fang, Xiaolei Li, Lihua Xie

This paper investigates the localization problem of a network in 2-D and 3-D spaces given the positions of anchor nodes in a global frame and inter-node relative measurements in local coordinate frames.


3-D Distributed Localization with Mixed Local Relative Measurements

no code implementations18 Dec 2023 Xu Fang, Xiaolei Li, Lihua Xie

Each node holds a local coordinate frame without a common orientation and can only measure one type of information (relative position, distance, relative bearing, angle, or ratio-of-distance measurements) about its neighboring nodes in its local coordinate frame.


Distributed Localization in Dynamic Networks via Complex Laplacian

no code implementations18 Dec 2023 Xu Fang, Lihua Xie, Xiaolei Li

Different from most existing distributed localization approaches in static networks where the agents in a network are static, this paper addresses the distributed localization problem in dynamic networks where the positions of the agents are time-varying.

Integrated Relative-Measurement-Based Network Localization and Formation Maneuver Control (Extended Version)

no code implementations28 Oct 2023 Xu Fang, Lihua Xie, Xiaolei Li

This paper studies the problem of integrated distributed network localization and formation maneuver control.


Radial velocity map of solar wind transients in the field of view of STEREO/HI1 on 3 and 4 April 2010

no code implementations8 Mar 2021 Xiaolei Li, Yuming Wang, Jingnan Guo, Rui Liu1, Bin Zhuang

According to the obtained spatial distributions of height and radial velocity of the CME, we analyzed the self-similarity of the radial expansion of the CME ejecta.

Generalized Emergent Dark Energy Model and the Hubble Constant Tension

no code implementations5 Mar 2021 Weiqiang Yang, Eleonora Di Valentino, Supriya Pan, Arman Shafieloo, Xiaolei Li

In particular, we find that $\Lambda$CDM model is disfavored at more than $2\sigma$ CL for most of the observational datasets considered in this work and PEDE is in agreement with Planck 2018+BAO+R19 combination within $1\sigma$ CL.

How flux feeding causes eruptions of solar magnetic flux ropes with the hyperbolic flux tube configuration?

no code implementations29 Jan 2021 Quanhao Zhang, Rui Liu, Yuming Wang, Zhenjun Zhou, Bin Zhuang, Xiaolei Li

But it is unclear how flux feeding influences coronal flux ropes that are wrapped by hyperbolic flux tubes (HFT), and whether it is able to cause the flux-rope eruption.

Sound source ranging using a feed-forward neural network with fitting-based early stopping

no code implementations1 Apr 2019 Jing Chi, Xiaolei Li, Haozhong Wang, Dazhi Gao, Peter Gerstoft

Based on FEAST, when the evaluated range error of the FNN reaches the minimum on test data, stopping training, which will help to improve the ranging accuracy of the FNN on the test data.

Monet: A User-oriented Behavior-based Malware Variants Detection System for Android

no code implementations10 Dec 2016 Mingshen Sun, Xiaolei Li, John C. S. Lui, Richard T. B. Ma, Zhenkai Liang

We present the design and implementation of MONET, which has a client and a backend server module.
