Abstract Integral imaging (II) display, one of the most critical true-3D display technologies, has received increasing research recently. Significantly, an achromatic metalens array realized a broadband metalens-array-based II (meta-II). However, past micro-scale arrays were incompatible with commercial micro-displays; furthermore, elemental image (EIA) rendering is always slow. The two hinders in device and algorithm prevent meta-II from being used for practical video-rate near-eye displays...
The “defocused transmit-focused receive” (DTFR) mode in the distributed multiple-input multiple-output (MIMO) radar network is very effective multitarget tracking. In this mode, a completely defocused beam transmitted and focused receive synthesized so that MIMO capable of tracking targets independently. A joint target assignment power allocation (TAPA) strategy developed for multiple networks cluttered environment using DTFR mode. Our aim to achieve better system accuracy under constraints...
This article develops a joint subarray selection and power allocation (JSSPA) strategy for tracking multiple targets in clutter environments using large-scale distributed MIMO radar networks. The mechanism of our is to implement the best resource on basis information recursive manner, aiming at improving overall accuracy. By integrating with reduction factor, we derive predicted conditional Cramér-Rao lower bound (PC-CRLB) clutter, which offers more accurate measure target state estimate...
Abstract Short fiber reinforced polymers (SFRP) based on unidirectionally arrayed chopped strands (UACS) offer exceptional formability and great mechanical properties. To ensure its stability safety in applications, it is crucial to enhance the impact performance of UACS laminates. This study investigated low‐velocity (LVI) responses damage evolution laminates with different slit sizes continuous carbon polymer (CFRP) under various energies (4, 7, 11 J). The curves force energy were recorded...

Accurately classifying the surrounding rock of tunnel face is essential. In this paper, we propose a machine learning-based automatic classification and dynamic prediction method rocks using data monitored by computerized drilling trolley based on intelligent mechanized construction process for blasting tunnels. This provides auxiliary support decision at site. First, solves imbalance in samples constructing Synthetic Minority Oversampling Technique (SMOTE) algorithm 500 parameters covering...
This study investigates the opening size effect of a novel short fiber reinforced quasi-isotropic composite laminate with unidirectionally arrayed chopped strands (UACS) under tensile load by approaches simulations and experiments. The layup [45/0/-45/90]s was used to fabricate carbon laminates various central hole diameter from 4 mm 10 mm. Low notch sensitivity strength reduction rate were observed in UACS open-hole laminates. It found that when width ratio (d/w) is less than 20%, 80%...
Abstract Accurate daily runoff prediction plays an important role in the management and utilization of water resources. In order to improve accuracy prediction, this paper proposes a deep neural network (CAGANet) composed convolutional layer, attention mechanism, gated recurrent unit (GRU) network, autoregressive (AR) model. Given that sequence is abrupt unstable, it difficult for single model combined obtain high-precision predictions directly. Therefore, uses linear interpolation method...
Abstract The mining of coal mines in western China needs to focus on protecting groundwater. A non-hydrophilic similar material for simulating the development and hydraulic conductivity weakly cemented overlying strata fractures was developed. Fine sand, coarse gypsum are used as aggregates. Paraffin Vaseline binders. ratios sandy mudstone medium-grained sandstone were determined by orthogonal experiments, simulation tests. results show that non-hydrophilicity rock-like materials can be...
