To address the increasingly serious issue of noise pollution, we propose an ultra-broadband and wide-angle acoustic absorber based on a periodic acoustic rigid-metaporous composite array. Numerical simulation results verify the broadband good acoustic absorption performance of the proposed absorber, which can achieve an average absorption coefficient of approximately 90.9% within the frequency band from 500 to 4000 Hz with incident angles ranging from -75 to +75 degrees, thus compensating for the shortcomings of traditional acoustic absorbers that are not as effective at low frequencies. This work will provide a new approach for ultra-broadband and wide-angle acoustic wave absorption and noise suppression. Copyright © 2024, The Authors. All rights reserved.

Orbit determination (OD) analysis for geostationary Communications, Ocean, and Meteorological Satellite (COMS) is presented. Since the orbital longitude of COMS is close to that of satellite tracking site, geometric singularity affects observability. For OD, we fix velocity increment by the wheel off-loading maneuver, and the azimuth angle tracking bias is not estimated because of observability problem. Final epoch of the propagated OD based on different data arc length is used for two-day orbit prediction. The difference between truth and 48-hour predicted orbit that contains the OD error shows 4-18 km Root-Sum-Squares (RSS) in 3-D sense (one sigma) in spite of the singularity problem. Thus an operational Orbit Determination and prediction (ODP) system for COMS fulfills the requirement for 18 km RSS (one sigma) predicted positioning knowledge.

Association rules mining algorithm using sharing mechanism niche leaping ant colony based on apriori algorithm

Journal of Computational and Theoretical Nanoscience 2015年第10期12卷 3223-3231页

作者： Wang, Yang Xu, Yakun Li, Gang Wang, Hongliang MicroNano System Research Center College of Information Engineering Taiyuan University of Technology Taiyuan Shanxi China Key Lab of Advanced Transducers and Intelligent Control System of the Ministry of Education Taiyuan University of Technology Taiyuan Shanxi China Ministry of Education North University of China Taiyuan China

Based on the alarm data in the information communication network under the context of big data, the paper discusses the classic association mining algorithms of Apriori and FP-Growth with living examples, elaborates the ant colony algorithm and the niche technology, combines the Apriori algorithm thought and the Travelling Salesman Problem (TSP) of the ant colony algorithm, and proposes association rules mining algorithm using Sharing mechanism Niche Leaping Ant Colony based on Apriori algorithm (SN-APLAC algorithm). The algorithm achieves the thought of "leaping ants" by accelerating support calculation through a sparse linked list and setting the route point of non frequent item sets as "stimulation point" and retains the local optimal solution to further improve the quality of association rules mining utilizing the technique of sharing mechanism niche.

The aim of this paper is to compare two analytic detection algorithms for pipeline leaks in order to assess their effectivity. Parameters such as precision and velocity to detect and locate a leak, algorithm complexity, and application facilities are evaluated, with the purpose of finding the most useful algorithm for a future real-time implementation on a Mexican aqueduct.

Recently there has been considerable interest in the modeling and simulation of hybrid dynamic systems (HDS). As an effective modeling tool of discrete event dynamic systems, Petri nets have a dual nature of a graphical tool and a mathematical object. In this paper, an extension of Petri net named Generalized Differential Petri Nets (GDPN) is proposed to model HDS that have a combination of discrete-event evolution and continuous state evolution. Differential place and differential transition defined in [8] are used to model the numeral simulation of the continuous dynamic process, and the weights defined on the directed arcs that connects the differential transitions and differential places are extended from real number to real matrix. The marking of differential place are also enlarged from real number to real vector. Then the evolution rules and the modeling method of HDS with GDPN are introduced. Two examples are used to illustrate the modeling power of GDPN in HDS.

Infrared and visible light image fusion technology is a hot spot in the research of multi-sensor fusion technology in recent years. Existing infrared and visible light fusion technologies need to register before fusion because of using two cameras. However, the application effect of the registration technology has yet to be improved. Hence, a novel integrative multi-spectral sensor device is proposed for infrared and visible light fusion, and by using the beam splitter prism, the coaxial light incident from the same lens is projected to the infrared charge coupled device （CCD） and visible light CCD, respectively. In this paper, the imaging mechanism of the proposed sensor device is studied with the process of the signals acquisition and fusion. The simulation experiment, which involves the entire process of the optic system, signal acquisition, and signal fusion, is constructed based on imaging effect model. Additionally, the quality evaluation index is adopted to analyze the simulation result. The experimental results demonstrate that the proposed sensor device is effective and feasible.

In this paper, we investigate various surface structures of oxygen adsorption on Pd doping Zn-terminated ZnO (0001) by DFT. The results show that oxygen atom prefers to be adsorbed on the H sites of Pd substituting Zn atom of first Zn-O bilayers. The calculated PDOS indicates that a stronger interaction between adsorbed O2p and Pd4d orbitals has been happened at near the Fermi level. Finally, the bonding situation between adsorbed oxygen and surface is analyzed by electron density difference. The study reveals working mechanism of Pd-ZnO gas sensor, which is useful for finding the relationship between doping and sensitivity of sensor in experiment and theory.

Supersolid and pair correlations of the extended Jaynes-Cummings-Hubbard model on triangular lattices

Physical Review A 2019年第3期100卷 033614-033614页

We study the extended Jaynes-Cummings-Hubbard model on triangular cavity lattices and zigzag ladders. By using density-matrix renormalization-group methods, we observe various types of solids with different density patterns and find evidence for light supersolids, which exist in extended regions of the phase diagram of the zigzag ladder. Furthermore, we observe strong pair correlations in the supersolid phase due to the interplay between the atoms in the cavities and atom-photon interaction. By means of cluster mean-field simulations and a scaling of the cluster size extending our analysis to two-dimensional triangular lattices, we present evidence for the emergence of a light supersolid in this case also.
