Lunar Lander and Rover of China will be launched in 2013. It will finish the mission targets of lunar soft landing and patrol exploration. Lunar Rover has forward facing stereo camera pair (Hazcams) for hazard avoidance. Hazcams calibration is essential for stereo vision. The Hazcam optics are f-theta fish-eye lenses with a 120°×120° horizontal/vertical field of view (FOV) and a 170° diagonal FOV. They introduce significant distortion in images and the acquired images are quite warped, which makes conventional camera calibration algorithms no longer work well. A photogrammetric calibration method of geometric model for the type of optical fish-eye constructions is investigated in this paper. In the method, Hazcams model is represented by collinearity equations with interior orientation and exterior orientation parameters [1] [2]. For high-precision applications, the accurate calibration model is formulated with the radial symmetric distortion and the decentering distortion as well as parameters to model affinity and shear based on the fisheye deformation model [3] [4]. The proposed method has been applied to the stereo camera calibration system for Lunar Rover. © Copyright SPIE.

In this paper, we present a series of composite metamaterial THz modulators that combine optimized metallic metasurface with AlGaN/GaN heterostructure array to realize the amplitude and phase modulation of terahertz waves. Embedded with the nanostructured 2DEG layer of GaN HEMT, the resonance intensity and surface current circuit of the resonant modes in the metamaterial unit can be dynamically manipulated by electrical control of the carrier distribution and depletion of the 3 nm-2DEG. In real-time dynamic tests, THz spatial amplitude modulator achieves 93% modulation depth and 3 GHz modulation speed. THz spatial phase modulator achieves a 137 degree phase shift with an external controlling voltage of only several volts in the THz transmission mode.

Task-free functional connectivity in animal models provides an experimental framework to examine connectivity phenomena under controlled conditions and allows for comparisons with data modalities collected under invasive or terminal procedures. Currently, animal acquisitions are performed with varying protocols and analyses that hamper result comparison and integration. Here we introduce StandardRat, a consensus rat functional magnetic resonance imaging acquisition protocol tested across 20 centers. To develop this protocol with optimized acquisition and processing parameters, we initially aggregated 65 functional imaging datasets acquired from rats across 46 centers. We developed a reproducible pipeline for analyzing rat data acquired with diverse protocols and determined experimental and processing parameters associated with the robust detection of functional connectivity across centers. We show that the standardized protocol enhances biologically plausible functional connectivity patterns relative to previous acquisitions. The protocol and processing pipeline described here is openly shared with the neuroimaging community to promote interoperability and cooperation toward tackling the most important challenges in neuroscience.

We search for gravitational-wave (GW) transients associated with fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project, during the first part of the third observing run of Advanced LIGO and Advanced Virgo (2019 April 1 15:00 UTC-2019 October 1 15:00 UTC). Triggers from 22 FRBs were analyzed with a search that targets both binary neutron star (BNS) and neutron star-black hole (NSBH) mergers. A targeted search for generic GW transients was conducted on 40 FRBs. We find no significant evidence for a GW association in either search. Given the large uncertainties in the distances of our FRB sample, we are unable to exclude the possibility of a GW association. Assessing the volumetric event rates of both FRB and binary mergers, an association is limited to 15% of the FRB population for BNS mergers or 1% for NSBH mergers. We report 90% confidence lower bounds on the distance to each FRB for a range of GW progenitor models and set upper limits on the energy emitted through GWs for a range of emission scenarios. We find values of order 10⁵¹-10⁵⁷ erg for models with central GW frequencies in the range 70-3560 Hz. At the sensitivity of this search, we find these limits to be above the predicted GW emissions for the models considered. We also find no significant coincident detection of GWs with the repeater, FRB 20200120E, which is the closest known extragalactic FRB. © 2023. The Author(s).

A novel optimization strategy for job scheduling based on double hierarchy

引用

Journal of Engineering science and technology Review 2017年第1期10卷 61-67页

作者： Zhao, Guozeng Gao, Xiang Zheng, Weidong Lv, Zhiguo School of Computer Science and Engineering Luoyang Institute of Science and Technology Luoyang471023 China Department of Control and Computer Engineering Politecnico di Torino Corso Duca degli Abruzzi 24 Torino10129 Italy State Key Laboratory of Integrated Services Networks Xidian University Xi'an710071 China

At present, the high-performance cluster system has been widely applied to multitask and multi-user data processing procedures. However, computation loads can be influenced by the job scheduling optimization strategy (JSOS) of the cluster system, which can cause imbalance during job scheduling process, job starvation, and resource fragmentation. This situation can further result to problems, such as dissatisfactory resource utilization and lengthy job response, turnover, and completion times. First, a double hierarchical job scheduling model was proposed in this study to optimize the job scheduling strategy of the cluster system. Second, this study analyzed the hierarchical tasks in the scheduling model and the factors, namely, resource utilization and job completion time that influence them. The reasonability of the JSOS was also verified. Finally, the optimization strategy for job scheduling was compared with the first-come, firstserved (FCFS) and FirstFit strategies. Result shows that compared with FCFS and FirstFit strategies, the proposed job scheduling strategy increased resource utilization by 6.3% and 0.8%, and reduced average response time by 22.05% and 1.12%, average turnover time by 9.82% and 2.01%, and completion time by 10.45% and 1.11%, respectively. Thus, the proposed double hierarchical job scheduling strategy not only improves system resource utilization but also reduces job response, turnover and job completion times. The experimental result is consistent with the expected requirements, and the study provides a feasible scheme for the job scheduling optimization problem in the cluster system. © 2017 Eastern Macedonia and Thrace Institute of technology.

Single-photon sources are of great interest because they are key elements in different promising applications of quantum technologies. Here we demonstrate a highly efficient tunable on-demand microwave single-photon source based on a transmon qubit with the intrinsic emission efficiency more than 99%. To confirm the single-photon property of the source, we study the single-photon interference in a Hanbury-Brown-Twiss (HBT) type setup and measure the correlation functions of the emission field using linear detectors with a GPU-enhanced signal processing technique. The antibunching in the second-order correlation function is clearly observed. The theoretical calculations agree well with the experimental results. Such a high-quality single-photon source can be used as a building block of devices for quantum communication, simulations and information processing in the microwave regime.

Recent years have witnessed much interest in Low Power Wide Area (LPWA) technologies, which are gaining unprecedented momentum and commercial interest towards the realisation of the Internet of Things (IoT). Long Range (LoRa), as a representative LPWA technology, has the potential to satisfy the growing demand for the longer range and larger amount connectivities in vehicular communication networks. In this paper, LoRa is firstly applied into two typical vehicular networks, namely Vehicle-to-Infrastructure (V2I)and Vehicle-to-Vehicle (V2V), and performance of LoRa schemes with different parameter configurations are evaluated and compared. Further, Monte Carlo simulations indicate that the schemes equipped with higher bandwidth or lower spreading factor exhibit significant advantages in combating the fast fading caused by Doppler effect in networks. © 2018 IEEE.

A causal matrix-based method for key process identification: A case study in heavy medium coal preparation

引用

International Journal of Performability Engineering 2018年第6期14卷 1341-1351页

作者： Yuan, Qingwen Li, Zhaojun Jia, Shun Jin, Zhenzhen Department of Finance and Economics Shandong University of Science and Technology Jinan Shandong250031 China Department of Industrial Engineering and Engineering Management Western New England University Springfield Massachusetts01119 United States Department of Industrial Engineering Shandong University of Science and Technology Qingdao266590 China State Key Laboratory of Mining Disaster Prevention and Control Shandong University of Science and Technology Qingdao266590 China National Demonstration Center for Experimental Mining Engineering Education Shandong University of Science and Technology Qingdao266590 China

In order to identify key processes in coal mining and preparation processes for optimized process control and quality improvement, a modified causal matrix method is proposed to reduce quality defects and avoid unnecessary investments. The limitations of existing key processes identification methods are reviewed with the identified key process identification requirements in the context of the coal mining industry. The key Process Identification Method of Coal Preparation (CP-KPIM) is proposed based on a redesigned causal matrix method, which considers four aspects, i.e., the systematic production data set, multi-dimension quality measures, the correlation between processes and quality characteristics, and a unified total process criticality assessment method. The implementation steps of CP-KPIM are demonstrated in details through a case study in a heavy medium coal preparation plant. Based on the total process criticality assessments, eleven key processes were identified from a total of fifty-three processes. In addition, the CP-KPIM has demonstrated significant productivity improvement through the process capability analysis. © 2018 Totem Publisher, Inc. All rights reserved.
