Restrictive Effect Analysis of Context on the Sentences Choice in the Perspective of Contemporary Pragmatics

Jie Bai

There is a very close relationship between context and sentence choice, the specific context must be matched with the language form. This paper focuses on the context of the functional point of view to explore the role of context on constraints of the sentence choice from the perspective of pragmatic language.

Non-Destructive Monitoring of Maize Nitrogen Concentration Using a Hyperspectral LiDAR: An Evaluation from Leaf-Level to Plant-Level

Remote Sensing (2021)

Kaiyi Bi Zheng Niu Shunfu Xiao Jie Bai Gang Sun

Advanced remote sensing techniques for estimating crop nitrogen (N) are crucial for optimizing N fertilizer management. Hyperspectral LiDAR (HSL) data, with both spectral and spatial information of the targets, can extract more plant properties than traditional LiDAR and hyperspectral imaging systems. In this study, we tested the ability of HSL in terms of estimating maize N concentration at the leaf-level by using spectral indices and partial least squares regression (PLSR) methods. Subsequently, the N estimation was scaled up to the plant-level based on HSL point clouds. Biomass, extracted with structural proxies, was utilized to exhibit its supplemental effect on N concentration. The results show that HSL has the ability to extract N concentrations at both the leaf-level and the canopy-level, and PLSR showed better performance (R2 > 0.6) than the single spectral index (R2 > 0.4). In comparison to the stem height and maximum canopy width, the plant height had the strongest ability (R2 = 0.88) to estimate biomass. Future research should utilize larger datasets to test the viability of using HSL to monitor the N concentration of crops, which is beneficial for precision agriculture.

Reactive Power Optimization for Including Wind Farms Based on Improved Differential Evolution Algorithm

Shenyang Nongye Daxue xuebao (2010)

Jie Bai

Reactive power optimization for wind power system is a non-linear problem with multi-state variables and multi-constraints.As differential evolution algorithm(DE) has a shortcoming of easily plunging into a local optimal solution,an improved DE was put forward.For the basic differential evolution algorithm,the increasing quadratic function crossover operator was added to increase the convergence speed.When the algorithm runs into prematurity,the random perturbation mutation strategy is adopted for the best individual and the randomly selected individual to help them being out of local minimum.The results of system simulation showed that this algorithm can seek the best result of overall situation effectively and increase the convergence speed obviously,having favorable self-adaptive characteristic.

A Preliminary Study of the Validation of Land Surface Models with Large Aperture Scintillometer Data

The application of large aperture scintillometer observations to the validation of land surface models has important significances in better understanding and describing the influences of land surface processes on climate change.With observational data from stations,field survey data,and remote sensing data,the land surface processes of Miyun and Arou,two typical flux observation stations in northern China,were simulated by SiB2 model at the spatial scale of 1km2.The simulation was validated by the sensible heat fluxes obtained by Large Aperture Scintillometer(LAS) and Eddy Covariance measurement(EC).The results showed that: ①SiB2 has given a good simulation of the sensible heat flux as well as its diurnal variation and seasonal variation;②The validation of large scale simulation by LAS can avoid the disadvantage of EC,such as energy disclosure and spatial scale differences with model simulation,and could give better results.

MFSPest: A multi-scale feature selection network for light-trapped agricultural pest detection

Journal of Intelligent & Fuzzy Systems (2023)

Ze Yang Xianliang Jiang Guang Jin Jie Bai

Accurate and fast pest detection is crucial for ensuring high crop yield and quality in modern agriculture. However, there are significant challenges in using deep learning for pest detection, such as the small proportion of pest individuals in the image area, complex backgrounds in light-trapped pest images, and an unbalanced distribution of pest species. To address these problems, we propose MFSPest, a multi-scale feature selection network for detecting agricultural pests in trapping scenes. We design a novel selective kernel spatial pyramid pooling structure (SKSPP) in the feature extraction stage to enhance the network’s feature extraction ability for key regions and reduce its focus on irrelevant background information. Furthermore, we present the equalized loss to increase the loss weights of rare categories and improve the distribution imbalance among pest categories. Finally, we build LAPD, a light-trapping agricultural pest dataset containing nine pest categories. We conducted experiments on this dataset and demonstrated that our proposed method achieves state-of-the-art performance, with Accuracy, Recall, and mean Average Precision (mAP) of 89.9%, 92.8%, and 93.6%, respectively. Our method satisfies the requirements of pest detection applications in practical scenarios and has practical value and economic benefits for use in agricultural pest trapping and management.
