Due to the increasing proportion of wind power connected grid, day-ahead prediction plays a more and important role in operation system. This paper proposes short-term model based on deep learning (DWT_AE_BiLSTM). Firstly, discrete wavelet transform (DWT) is used denoise data, then an autoencoder (AE) technology extract data features, finally, bidirectional long memory (BiLSTM) for prediction. To verify effectiveness proposed DWT_AE_BiLSTM model, we studied three different stations compared...
Abstract The study reveals the dynamic impact damage resistance and energy absorption of oxygen/argon/nitrogen multiple plasma modified ultra‐high molecular weight polyethylene (UHMWPE) fiber reinforced composites. interface bonding properties composite were studied by microsphere debonding test, low‐velocity high‐velocity test. parameters are optimized based on quadratic polynomial equation. was evaluated from aspects ballistic limit velocity, failure mode dissipation mechanism. results...

To study the effects on coal structure and microbial community diversity during CO2 storage in deep unminable water-bearing seams, lignite mining area of Inner Mongolia was selected as research object. The simulation experiments supercritical-CO2 (ScCO2)-H2O-microbial-coal interaction under different pressure conditions performed by using an autoclave. Then solid–liquid phases before after reaction were analysed XPS, low-temperature liquid nitrogen adsorption, 16S rRNA other testing methods....
This research aimed to develop a new method for clean utilization and treatment of landfill leachate solid waste weathered coal. Landfill coal were adopted combined anaerobic fermentation methane production. The characteristics microbial community, mechanism biological production, broth residue co-fermentation analyzed through metagenomics, soluble organic matter detection thermogravimetric (TG) analysis. obtained results revealed that increased production by 80.1%. Syntrophomonas,...
In this paper, we propose a vectorized noncircular MUSIC (VNCM) algorithm based on the concept of coarray, which can construct difference and sum (diff–sum) for direction finding (NC) quasi-stationary sources. Utilizing both NC property Khatri–Rao product, proposed method be applied to not only ULA but also sparse arrays. addition, utilize characteristic instead spatial smoothing solve coherent issue generated by product operation so that available degree freedom (DOF) constructed virtual...
The annual output of shale gas from the Wufeng-Longmaxi formations in South China reached 15.4 × 109 m3 2019, which makes Sichuan basin second-largest producing area world. Based on data more than 1000 samples taken typical drilling and outcrop profiles Weiyuan, Changning, Fuling, Wuxi areas China, characteristics differential enrichment are analyzed main controlling factors discussed. study shows that has some both vertical lateral orientations. In orientation, sweet-spot intervals...
Millimeter wave (MMW) imaging systems have been widely used for security screening in public places due to their advantages of being able detect a variety suspicious objects, non-contact operation, and harmlessness the human body. In this study, we propose an innovative, multi-dimensional information fusion YOLO network that can aggregate capture multimodal cope with challenges low resolution susceptibility noise MMW images. particular, data aggregation module is developed adaptively...
Abstract This study reveals the impact resistance of shear thickening gel (STG) impregnated four‐layer regular angle interlocking fabrics (AIF) composites. The effects STG parameters, including reaction time, temperature, and ratio, on rheological characterization mechanical properties STG/AIF flexible composites were investigated. results show that increase in parameters accelerated formation BO crosslink bonds within STG. energy storage modulus increased by three orders magnitude for a...
Recently, the concept of difference and sum co-array (DSCa) has attracted much attention in array signal processing due to its high degree freedom (DOF). In this paper, DSCa nested (NA) is analyzed then an improved configuration known as diff-sum (DsNA) proposed. We find prove that set for NA contains all elements set. Thus, there exists dual characteristic between two sets, i.e., result any sensor locations NA, one equivalent non-negative/non-positive other can always be found. order reduce...
High electrical and thermal conductivity is beneficial to shape recovery performances of electroactive memory polymer composites. In this work, the chopped carbon fiber (CCF) was processed into silver plated (Ag/CCF), Ag/CCF filled hydro-epoxy (H-EP) resin prepare electrically responsive The Ag/CCF/H-EP composites show good compared CCF/H-EP When content reaches 1.8 wt%, e reach threshold conductivity, percolation. H-EP composite with 5.4 wt% 2.33 W/(m·K), which 2.6 times 12 that matrix...
