The development of high-performance electrocatalyst with earth-abundant elements for water-splitting is a key factor to improve its cost efficiency. Herein, noble metal-free bifunctional was synthesized by facile pyrolysis method using sucrose, urea, Co(NO3)2 and sulfur powder as raw materials. During the fabrication process, Co, S co-doped graphitic carbon nitride (g-C3N4) first produced, then this in-situ-formed template further induced generation N, tri-doped graphene coupled Co...
The spinel Li4Ti5O12/rutile-TiO2@carbon (LTO-RTO@C) composites were fabricated via a hydrothermal method combined with calcination treatment employing glucose as carbon source. coating layer and the in situ formed rutile-TiO2 can effectively enhance electric conductivity provide quick Li+ diffusion pathways for Li4Ti5O12. When used an anode material lithium-ion batteries, rate capability cycling stability of LTO-RTO@C improved comparison those pure Li4Ti5O12 or Li4Ti5O12/rutile-TiO2....
The goal of this paper is to investigate the security performance multi-antenna unmanned aerial vehicle (UAV)-enabled mobile relaying system with a destination in presence eavesdropper. To improve secrecy outage probability performance, we propose location-based three dimensional (3D) beamforming scheme without channel state information and end, first derive expression for uniform linear arrays (ULAs) circular (UCAs), which valid arbitrary values parameters. practicable UAV-enabled as...
Automated large-scale farmland preparation operations face significant challenges related to path planning efficiency and uniformity in resource allocation. To improve agricultural production reduce operational costs, an enhanced method for land paths is proposed. In the initial stage, unmanned aerial vehicles (UAVs) are employed collect data from field, which then used construct accurate farm models. For single-field operations, a approach developed that minimizes energy consumption. The...
Correlation filter (CF) based tracking algorithms have tremendously contributed to the field of visual due high computational efficiency and competitive performance. Nonetheless, most CF-based trackers are vulnerable influence occlusion boundary effect, which results in suboptimal In this article, we propose saliency guided via correlation with log-Gabor robustify its performance under effect challenges. Firstly, CF get a robust appearance model. The is adopted preprocess sequence gain...
Correlation filter based tracking algorithms have received significant attention in visual due to their accuracy and speed. However, it is susceptible distractors performs poor when faced with occlusion severe deformation. In this paper, we introduce a distractor-aware long-term correlation distinguish the target background. Firstly, information entropy weighted feature utilized deal different scenarios dynamically. Secondly, order facilitate tracker from which lead inaccurate localization,...
Frequency synthesizer is an important component in the modem electronic systems. This paper studied a kind of frequency UAV system and put forward improvement method for DDS (Direct Digital Synthesis) & PLL (Phase Locked Loop) hybrid synthesizer. Be further to raise performance fast locking noise immunity ability method, with Analog Adaptive Bandwidth Control (AABC) has been designed this paper. The new-type AABC presented based on conventional Charge pump circuit. block can control loop...
The configuration thought of industrial control automation field had been led into, Configuration Art is applied to test field. A pattern equipment put forward according the multiform requirement UAV (Unmanned Aerial Vehicle) test. With various form bus instrument, hardware platform mix-bus have founded; Based on method Hierarchical Intelligent Control, solved automatically generation problem process, so, a software developed. Under this comprehensive testing system, need system can be...

Climate change inevitably affects vegetation growth in the Tibetan Plateau (TP). Understanding dynamics of phenology and responses to climate are crucial for evaluating impacts on terrestrial ecosystems. Despite many relevant studies conducted past, there still remain research gaps concerning dominant factors that induce changes start date growing season (SOS). In this study, spatial temporal variations SOS were investigated by using a long-term series Normalized Difference Vegetation Index...

This paper probes into issues of synchronization in fixed time (FXT) or preassigned (PST) delayed memristive quaternion-valued neural networks (MQVNNs), which involved are (QV) state variables, external inputs, rates neuron self-inhibition, activation functions and connection weights. Uncommonly, instead dividing the original QV system four separated real-valued subsystems, this analyzes wholly through introducing a sign function two norms. Incidentally, several new properties norms deduced,...
