This study proposes a novel color image encryption algorithm based on 3D chaotic Hopfield neural network and random row–column permutation. First, is proposed to produce the sequence for generating diffusion permutation keys. Then, rows columns of original are randomly arranged according key in process. Three subgraphs formed by separating R, G, B components Each three split along form parts; left middle parts exchanged. keys used encrypt each parts. Finally, individually encrypted stitched...
Instance level detection and segmentation of thoracic diseases or abnormalities are crucial for automatic diagnosis in chest X-ray images. Leveraging on constant structure disease relations extracted from domain knowledge, we propose a structure-aware relation network (SAR-Net) extending Mask R-CNN. The SAR-Net consists three modules: 1. the anatomical module encoding spatial between parts. 2. contextual aggregating clues based query-key pair RoI lung fields. 3. propagating co-occurrence...
Object rearrangement is important for many applications but remains challenging, especially in confined spaces, such as shelves, where objects cannot be accessed from above and they block reachability to each other. Such constraints require motion planning collision checking calls, which are computationally expensive. In addition, the arrangement space grows exponentially with number of objects. To address these issues, this work introduces a lazy evaluation framework local monotone solver...
For rearranging objects on tabletops with overhand grasps, temporarily relocating to some buffer space may be necessary. This raises the natural question of how many simultaneous storage spaces, or "running buffers," are required so that certain classes tabletop rearrangement problems feasible. In this work, we examine problem for both labeled and unlabeled settings. On structural side, observe finding minimum number running buffers (MRB) can carried out a dependency graph abstracted from...
Cementing quality can’t meet the requirements in deep and ultra-deep wells cementing because of many factors such as long open hole section, multiple pressure system, high temperature pressure. In order to solve problem wells, retarder fluid loss additive were studied, then cement slurry system for developed performance was evaluated. The results show that has steady temperature, adjustable thickening time, less loss, good settlement stability, compressive strength, all which can requirement...
Based on the statistical analysis of China Water Resources Bulletin, environmental situation Bulletin and national statistics yearbook during 2008-2019, we summarized water resources environment quality seven major basins, proportion, main pollutants change trend various types are discussed. Meanwhile, wastewater discharge pollution also analyzed. The results show that in recent years, overall is improving, but still not optimistic. only basis for human survival development, a strategic...
The rotary wing UAV has an important practical significance in the military and civil fields. ability of autonomous flight control obstacle avoidance is precondition for ensuring safe unmanned aerial vehicles. This paper uses contour map data to see closed curve as obstacle, extracts height points, removes insertion values outside measured elevation get polygonal obstacles carry out path planning. simulation results show that algorithm feasible some advantages complex terrain, such mountain...
A self-[3+2] annulation reaction of pyridinium salts has been developed for the synthesis N -indolizine-substituted pyridine-2(1 H )-ones.
The aim of our study was to develop a nomogram predicting the early failure rate Pavlik harness in infants under 6 months age with developmental dysplasia hip (DDH). We retrospectively analyzed clinical data 227 patients (372 hips) DDH who were treated at institution from August 2019 January 2022. Fifty-eight (102 failed treatment, and 169 (270 successfully treated. Then, independent risk factors for treatment determined via univariate multivariate logistic regression used generate harness....
Performing object retrieval in real-world workspaces must tackle challenges including \emph{uncertainty} and \emph{clutter}. One option is to apply prehensile operations, which can be time consuming highly-cluttered scenarios. On the other hand, non-prehensile actions, such as pushing simultaneously multiple objects, help quickly clear a cluttered workspace retrieve target object. Such however, also lead increased uncertainty it difficult estimate outcome of operations. The proposed...
Abstract The problem of neutral-point potential balance is always an inherent three-level inverters. In this paper, improved varied virtual-space-vector modulation method proposed to improve the neutral point capability Firstly, virtual medium vector redefined, and distribution coefficient k introduced control amount charge flowing out point. Secondly, based on principle compensating maximum in a switching period, appropriate composite voltage selected dynamic response control. simulation...

Good lattice point (GLP) sets are many of points uniformly distributed over the domain interest and thus have good space-filling property. GLP frequently used in applications, such as quasi-Monte Carlo, dimensional integral, structural reliability evaluation other areas. However, number dimensions increases, amount calculation also increases could not get a better generating vector to obtain especially high-dimensional space. To handle this problem, new method is proposed for space, which...
