Abstract The inefficient delivery of herbicides causes unpleasant side effects on the ecological environment. Protoporphyrinogen oxidase (PPO)‐inhibiting rely presence external light to exert activities and thus their performance in field is extremely susceptible Here, taking acifluorfen (ACI) as a model PPO‐inhibiting herbicide enhance efficacy by boosting utilization rate sunlight, amphiphilic cationic CDs (CPC‐CDs) from cetylpyridinium chloride (CPC) precursor, first prepared...
The conventional application of fungicides suffers from substantial off-target loss due to photolysis, evaporation, and rain washing, resulting in risks the environment human health. To address these limitations, self-assembled nanopesticides based on two kinds have emerged as precision agrochemical delivery platforms that synchronize enhanced bioactivity with environmental risk mitigation. Herein, core-shell structured nanoparticles (PRO-PYR NPs) an average particle size 263 nm were...
In urban environments, the positioning performance of global navigation satellite system (GNSS) degrades severely due to harsh environment, which will be improved after fused with a strap-down inertial (SINS). However, error accumulation, ability GNSS/SINS integration also decrease significantly during frequent GNSS outages. To improve accuracy, we use stereo vision enhance integration, where and are loosely coupled tightly SINS under Earth-centered Earth-fixed (ECEF) frame, respectively....
GNSS (Global Navigation Satellite System) observation insufficiency limits the development of voxel-based computerized ionospheric tomography (CIT) technique. Electron densities voxels without cannot be accurately estimated by commonly used algebraic reconstruction techniques. In this study, we proposed a compressed sensing technique (CST) based on dictionary learning for tomography. Specifically, K-SVD (singular value decomposition) algorithm was training sets that are derived from NeQuick...
The continual miniaturization of mass-market sensors built in mobile intelligent terminals has inspired the development accurate and continuous navigation solution for portable devices. With release Global Navigation Satellite System (GNSS) observations from Android Nougat system, smartphones can provide pseudorange, Doppler, carrier phase GNSS. However, it is still a challenge to achieve seamless positioning consumer applications, especially environments where GNSS signals suffer low...
Scale-space behavior of corners is important for developing an efficient corner detection algorithm. In this paper, we analyze the scale-space with Laplacian Gaussian (LoG) operator on a planar curve which constructs Scale Space (LSS). The analytical expression Scale-Space map (LSS map) obtained, demonstrating corners, based newly defined unified model. With formula, some summarized. Although LSS demonstrates similarities to Curvature (CSS), there are still differences. First, no new extreme...
Nowadays, the autonomous vehicle has undergone an impressive development, in which one of most challenging tasks is to pursue high-precision and continuous navigation complex scenarios. However, GNSS signals are very likely be blocked inertial system suffers from error drift over time. To achieve centimeter-level positioning accuracy, a tightly-coupled model built via fusing visual, GNSS, INS measurements, based on priori visual feature map. The map first generated by mobile surveying...
This article embarks on a comparative analysis to uncover the role of island as liminal space in William Shakespeare’s The Tempest and television series Lost , exploring its function facilitating redemption, fantasy, transformation. study elucidates how both narratives utilize not merely setting but crucial catalyst for character evolution thematic depth. Through an examination geographical, temporal, psychological dimensions liminality, demonstrates island’s pivotal where human complexity,...
In recent years, the rapid development of light remote sensing platforms and load has brought unprecedented opportunities for Unmanned Aerial Vehicle (UAV). order to meet high requirements applications such as precision agriculture, forestry monitoring environmental protection etc., we designed integrated a UAV-based hyperspectral imaging system. This paper briefly introduced composition system, discussed geometric processing data. A Spline function mosaic method based on Sparse Bundle...
In the era of intelligence, there is a huge demand for precise positioning in fields such as automatic driving, assisted and vehicle to everything. Due continuous high-precision capability, global navigation satellite system (GNSS) has been an important foundation large-scale location applications open-sky conditions. For land kinematic navigation, GNSS method based on Kalman filtering (KF) also become primary choice. However, general state model velocity acceleration KF lacks mining...
Although two-dimensional principal component analysis (2DPCA) extracts image features directly from 2D matrices rather than one dimensional vectors, 2DPCA is only based on the whole images to preserve total variances by maximizing trace of feature covariance matrix. Thus, cannot extract localized components, which are usually important for face recognition. Inspired nonnegative matrix factorization (NMF), features, we propose a novel algorithm recognition called (2DNPCA) components and...
Rapid urbanisation worldwide, especially in developing countries and areas, has led to the generation of large amounts construction demolition waste (C&DW).The resultant transportation demands pose severe threats safe secure city operation.By considering low-probability-high-consequence nature C&DW traffic accidents effectiveness route optimisation risk control, a risk-averse project was implemented.Furthermore, an optimal routing model based on conditional value at (CVaR) criterion is...
In the paper effect of negative pre-swirl on performance and flow in a centrifugal compressor stage are investigated by both experimental numerical methods. The results show that, at pre-swirl, whether pressure ratio is increased or not determined contest between energy transfer losses. At large losses IGV impeller obviously, which makes efficiency reduced dramatically. further analysis enhanced separation area depravation inlet condition main sources losses, while there almost no influence...
The collaboration among carriers by exchanging their transportation requests can reduce costs and consequently increase profits. Their profitability be further improved for with limited carbon emission permits if they also trade permits. In this paper, we propose a multi-round combinatorial double auction carrier in less than truckload both exchange trading, where each may play role as seller buyer. round of the auction, auctioneer first announces outsourcing price request unit trading Based...
