Pig weight and body size are important indicators for producers. Due to the increasing scale of pig farms, it is increasingly difficult farmers quickly automatically obtain size. this problem, we focused on a multiple output regression convolutional neural network (CNN) estimate DenseNet201, ResNet152 V2, Xception MobileNet V2 were modified into CNNs trained modeling data. By comparing estimated performance each model test data, was selected as optimal estimation model. Based height, shape,...
Ghost imaging is widely used in underwater active optical because of its simple structure, long distance, and non-local imaging. However, the complexity environment will greatly reduce quality ghost To solve this problem, an method based on generative adversarial networks proposed study. The generator network adopts U-Net with double skip connections attention module to improve reconstruction quality. In training process, total loss function sum weighted loss, perceptual pixel loss....
There exists the contradiction between imaging efficiency and quality for Fourier single-pixel (FSI). Although deep learning approaches have solved this problem to some extent, reconstruction at low sampling rate is still not enough meet practical requirements. To solve problem, inspired by idea of super-resolution, paper proposes paralleled fusing U-net attention mechanism improve FSI a rate. This builds generative adversarial network structure achieve recovery high-resolution target images...
Abstract To solve the problem of target recognition for flying‐birds and biomimetic flapping‐wing unmanned aerial vehicles (UAVs), a rectangular‐trapezoidal composite scattering model lidar detection bird wings has been proposed established. According to model, influence different line‐of‐sight angles on time–frequency distribution characteristics laser micro‐Doppler under same flapping wing motion was simulated studied. Then, frequency maximum shift are extracted based two‐dimensional...
The red imported fire ant, Solenopsis invicta Buren, is a significant urban, agricultural, and medical pest with wide distribution in the world. Surface or mound treatment using contact insecticide one of main methods to control S. invicta. In present study, cycloxaprid, newly discovered neonicotinoid insecticide, was evaluated for compared two referent insecticides, imidacloprid bifenthrin.Surfaces sand treated imidacloprid, bifenthrin caused high mortality workers, action cycloxaprid...
The application of plant growth-promoting rhizobacteria (PGPR) is a novel and an efficient strategy for improving soil degradation productivity. However, the effect PGPR on tobacco (Nicotiana tabacum L.) seedling growth under salt stress remains unclear. Here, microcosm experiments were designed to verify effects Bacillus cereus TC012 (BC), methylotrophicus TC023 (BM), amyloliquefacien TC037 (BA) grown in salt-affected soil. results showed that BC, BM, BA treatments significantly increased...
Since 2019, most ad exchanges and sell-side platforms (SSPs), in the online advertising industry, shifted from second to first price auctions. Due fundamental difference between these auctions, demand-side (DSPs) have had update their bidding strategies avoid unnecessarily high hence overpaying. Bid shading was proposed adjust bid intended for second-price order balance cost winning probability a first-price auction setup. In this study, we introduce novel deep distribution network optimal...
We proposed a new premixing method for photon-counting chirped amplitude modulation lidar (PCCAML). Earlier studies used the counting results of returned signal detected by Geiger mode avalanche photodiode detector (Gm-APD) to mix with reference signal, called postmixing method. use an alternative known as method, in which is directly modulate sampling gate width Gm-APD, and mixing completed before Gm-APD. This more flexible may perform better than terms signal-to-noise ratio cutting down...
White spot syndrome virus (WSSV) cause great harm in shrimp aquaculture. To understand the impact of viral infection on metabolism, we monitored culture farms Litopenaeus vannamei and collected samples different stages WSSV infection. The hepatopancreas were separated, then used gas chromatography mass spectrometry to detect metabolites. Through spectrometric analysis combined with multivariate data analysis, including PCA OPLS models, metabolism was significantly changed by indicated that...
A single photon avalanche diode (SPAD) is a high sensitivity detector that can work under weak echo signal conditions (≤1 per pixel). The measured digital signals be used to invert the range and reflectivity images of target with photon-efficient imaging reconstruction algorithm. However, existing algorithms are susceptible noise, which leads poor quality reconstructed target. In this paper, non-local sparse attention encoder (NLSA-Encoder) neural network proposed extract 3D information...
Controlling the backfat thickness of sows within an appropriate range during different production stages helps to increase number pigs weaned per sow year and ultimately enhances economic benefit pig farm. To obtain automatically, a estimation method based on machine vision is proposed. First, values 3D images buttocks 154 Landrace-Yorkshire crossbred were obtained using veterinary ultrasound meter Azure Kinect DK camera. After preprocessing utilizing Python 3.9.16 software, 10 external...
