The synthesis of metal halide perovskite/perovskitoid (MHP) photocatalysts with well-defined morphologies and facet-specific redox activity is technically challenging. Herein, using surfactants to control the arrangement 0D facet-shared [Bi2I9]3– dioctahedra building blocks, we successfully fabricated ordered perovskite Cs3Bi2I9 hexagonal prisms (CBI-HPs). Using Co2+ oxidation Pt4+ reduction as probes, photoexcited holes were shown spatially migrate edge (100) facets while electrons migrated...
Tailings ponds are a major hazard, and ranked 18th in the risk assessment of world accident hazards. The saturation line height is one most important factors that affects safety tailings ponds. Due to extremely complicated seepage boundary conditions ponds, precise calculation method urgently needed for predicting lines. Therefore, dynamic model should be investigated evaluate potential dam breakage. In this paper, based on an analysis various regions, we use long short-term memory (LSTM)...
This paper proposes a novel mechanical structure for power transmission lines inspection robot. The proposed composed of two identical lifting arms which are connected through middle girders with rotational joints. Symmetric is adopted as whole. There four mainly units, including motion open-close pressing units and rotating Walking obstacle-overcoming experiments on the simulative achieve desired effects in lab. It proves validity design maneuverability
Abstract Toward solving the actual operation problems of cascade hydropower stations under hydrologic uncertainty, this paper presents process extraction statistical characteristics from long-term optimal operation, and proposes a monthly function algorithm for through identification, processing, screening available information during operation. Applying to on Jinshajiang-Yangtze River system, modeled electric generation is shown have high precision provide benefits. Through comparison with...
For power transmission line detection, the multiple lasers of different wavelengths are used to location. Because sophisticated effects environmental light and background elements, it's difficult extract laser spot. So, this paper presented a method hybrid-laser image spot based on HSV space SVD for which in is formed target object. First, it extracts detection spots from image. Second, separates at wavelengths. Final, by experiment show that very effective can accurately
The discrete wavelet transform (DWT) has received considerable attention in the context of image processing due to its temporal and frequency characteristics. A specific VLSI architecture for forward/inverse DWT is presented. characteristics structure coefficients are utilized reduce circuit area. In addition, Booth algorithm balanced pipelines have been adopted which result a high throughput at 2 outputs per clock 5 clocks' pipeline latency. This design described verified by VHDL...
Online search queries have been used in various behaviour studies. As smoking has become a global health issue, studies that assess smoking-related behaviours using online faced limitations data utilization and study design. This conducts comparative analyses to investigate changes represented by volumes. Baidu from 2013 2017 were examine the volume containing four groups of keywords. A validation process was validate proposed method comparing with observed tobacco consumption. The results...
Due to the excellent properties such as high temperature resistance, corrosion good heat conduction and plasticity, MAX-phase materials have been considered one of candidate for cladding coating material in liquid metal cooled fast reactors. In this paper, evolution surface structure wettability Ti 3 SiC 2 under short-term LBE were studied experimentally. The samples immersed with saturated oxygen concentration 100, 300 500 h at 450°C. cross section morphology well composition distribution...
The design of climbing tower robot is mainly consisted two parts, including structure and control system. mechanical composed under actuated gripper a linear moving body. Based on the environment, designed. Further analyzing stress optimizing structure, based developed. system includes box body, communicate via WIFI. Finally testing doing in condition tower. experimental results show that principle prototype reasonable, feasible simple easy to operate.
The operation of the Three Gorges power station is most complex feature in China and even world, for it involves many factors such as flood control, generation, shipping water supply. This paper takes experimental reservoir impoundment 2008 example, demonstrated its impact on grid operation, meanwhile, put forward suggestions time, target, fluctuating process adjusting mechanism building, etc.
An adaptive fusion method of multi-focused image based on wavelet transform is presented. The match degree source considered as an threshold to decide whether maximum selection or weighted average be used for new coefficients sub-images. Experiments show that the proposed will obtain more information content and higher clarity after inverse than traditional methods.
Auto focus is an important technique to improve the automation for fund us camera. Selection of image sharpness evaluation function a key auto-focus technique. In order ensure focusing accuracy, new algorithm proposed. It uses definition retinal vessel edge as and combines rough search with fine together. The can be extracted fast accurately by confidence detection, result used auto-focus. And in decrease computation complexity, proposed only in-focus area. Experimental results show that...
The paper introduces the structure and basic theory of intrinsic safety explosion-proof, parameters each part principles selection. Emphasizes features、work earthing isolated barrier, which is used in explosion-proof industry process control system .
In order to promote the efficiency of actual hydropower system operation under limited inflow forecast, an Implicit Stochastic Optimization method using Support Vector Machine (SVM) theory is proposed in this paper derive long-term optimal operating rules. By applying model Jinsha-Yangtze river which largest base China, fitting performance rules explained and evaluated. System simulation results are given compared deterministic operation.
