The Common Aero Vehicle (CAV) is a hypersonic reentry weapon platform which was researched and developed by Boeing for USA FALCON program. Aiming at the reentry guidance problem of CAV under complicated path constraints and terminal conditions, a generation method of three-dimensional reentry reference trajectory is presented, and then a trajectory tracking controller is designed using linear quadratic regulator (LQR) theory. Lateral guidance is realized by using bank-reversal strategy of bank angle with the aid of the azimuth error corridor. Finally, the reentry guidance results for CAV are presented based on the above method. © 2011 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.

Power distribution operation involves the supervision and control of the operating states of a large distribution power grid. This technology includes several features, e.g. an abundant amount of application nodes, diversity of communication channels, etc. To accelerate the construction of state Grid-electric Internet of things and to guarantee the security of power grids data network and to consider the feature of power grids, a synthetic key management system is proposed. In the first section of this paper, from the perspective of maturity and practicality of related technology, the feasibility of combining quantum private communication and automatic power grid key management system is analyzed and demonstrated. In the next section, a key-management method, which is designed to combine quantum private communication technology and interaction with encryption devices, is designed and implemented. In the concluding section, to guarantee the integrity and atomicity in key storage processes and to achieve the quantum key storage, rollback mechanism of large-capacity quantum key storage is studied and discussed. © 2019 IEEE.

Optimization mechanisms of TiO 2 doping on functional properties of Gd 2 O 3 -Al 2 O 3 -SiO 2 glass ceramics for high-performance substrate applications

Ceramics International 2025年

作者： Daimeng Chen Tian Gao Bo Li School of Integrated Circuit Science and Engineering University of Electronic Science and Technology of China Chengdu 610054 China State Key Laboratory of Electronic Thin Films and Integrated Devices Chengdu 610054 China National Engineering Research Center of Electromagnetic Radiation Control Materials Chengdu 610054 China

This study systematically investigated the effects of TiO 2 on the crystallization, sintering characteristics, phase compositions, microstructure and functional properties of Gd 2 O 3 -Al 2 O 3 -SiO 2 (GAS) glass ceramics (GCs). The results revealed that TiO 2 , acting as a heterogeneous nucleating agent, significantly reduces the crystallization activation energy, thereby promoting nucleation and phase separation within the glass matrix. Furthermore, the partial substitution of Si 4+ with Ti 4+ in the glass network enhances its stability and densification. An optimal amount of TiO 2 improves the mechanical properties, reduces the thermal expansion coefficient, and minimizes signal delay and energy dissipation. Under sintering conditions of 1050°C, the GT3 GCs with 6 wt% TiO 2 exhibits exceptional comprehensive performance: σ 3p =321.8 MPa, H v = 8.96 GPa, E = 142.9 GPa, K IC = 2.46 MPa·m 1 / 2 , CTE = 6.40 ppm/◦C, ε r = 9.18 and tanδ = 3.5 × 10 -3 . These findings provide valuable insights into the doping modification of GAS glass ceramics and their potential for high-performance substrate applications.

Differential vertical screw conveyor is a new type of vertical screw conveyor. Use similarity theory to predict the conveying capacity of different particle material of differential vertical screw conveyor. First, using the similarity theory to establish the similarity index of a differential vertical screw conveyor and the similarity criteria is derived. Then measure the conveying capacity of millet and Thailand sago on the differential vertical screw conveyor test platform. At last, calculate the theoretical conveying capacity of Thailand sago through similarity theory according the conveying capacity data of millet. And construct analytic method for the conveying capacity of differential vertical screw conveyor. The result shows that the similarity theory banding correction coefficient is a good analysis method of the conveying capacity of differential vertical screw conveyor. © 2019 IEEE.

IEEE 802.15.4g Standard specifies multi-rate and multi-regional orthogonal frequency division multiplexing (MR-OFDM) physical layer, which supports principally outdoor, low-data-rate, wireless, smart metering utility network (SUN). The inter-channel interference (ICI) results in subcarrier frequency sampling offset and phase shift for signal on MR-OFDM. In this paper, phase tracking algorithms which estimate and compensate the offset on symbols are studied. A basic phase tracking method is presented that the phase rotation of reception signal can be recognized by using the data on the pilot tones. Furthermore, in order to mitigation the influence of noise, an average-based algorithm is proposed as a modified solution. In contrast with the basic method, the average-based algorithm enhances the reliability of phase tracking. Simulations of algorithms are assessed, which are in accordance with theoretical analysis. © 2019 IEEE.

With the construction of state Grid informatization, professional data such as operation inspection, marketing, and regulation have gradually shifted from offline to online. In recent years, cyberspace security incidents have occurred frequently, and national and group cybersecurity threats have emerged.
