Abstract.In recent years, artificial intelligence technology has been widely used to assist radiologists in diagnosing and analyzing medical images. The use of artificial intelligence technology can well assist doctors in the localization of lesions. However, the mainstream target detection models at this stage are difficult to be practically applied in medical systems because of factors such as the use of large backbone networks and high input resolution, which leads to low model accuracy and high consumption of computational resources. In this paper, we propose a fast detection speed and high … Read more →

Abstract.The plateau phenomenon is a phenomenon with regularity discovered by educational psychologists in the process of studying the formation of operational skills. Skill is an activity or mental activity to successfully complete a certain task. It is obtained through practice. When skills are formed, practice will temporarily stop at a certain stage. On the growth curve, it is shown as maintaining a certain level and continuously rising or falling, but after breaking through the plateau phenomenon, the curve can be seen to continue to rise. This article analyzes the manifestation of the plateau … Read more →

Abstract.To achieve semantic segmentation tasks in practical applications such as autonomous driving, networks need to efficiently process high-resolution images while maintaining high accuracy. This requires methods to effectively fuse spatial information in high-resolution images with semantic information in low-resolution images. To address this, this paper proposes a Multi-scale Fusion Convolutional Network (MFCNet) based on a single-branch network structure. In order to simultaneously handle information at different scales and assist the network in capturing a wide range of contextual information, … Read more →

Abstract.Earthquake is a kind of common and terrible sudden natural disaster. Frequent earthquake disasters bring inestimable loss of people and property to human society. Based on the earthquake background and considering the impact of aftershocks on emergency rescue activities, this paper constructs a multi-objective vehicle routing optimization model with the objectives of time, risk, fairness of material distribution and minimum cost. Through simulation examples, conclusions are drawn: Decision makers should first consider risk and time, when considering time, focus on considering the time window … Read more →

Abstract.To study the adsorption and diffusion mechanism of low-rank coal at the microscopic level, samples of Fukang low-rank coal were collected, and the elemental composition, carbon type distribution and functional group type of the Fukang low-rank coal structure were determined by elemental analysis (Ea), Fourier-transform interferometric radiometer (FTIR), X-ray photoelectron spectroscopy (XPS) and 13C nuclear magnetic resonance (13C NMR) experiments to construct a 2D molecular structure of the coal and a 3D macromolecular structure model. The adsorption and diffusion characteristics of methane … Read more →

Abstract.Reading is an important part of English teaching. Traditional English teaching has always on the basis of teaching new words, grammar and long and difficult sentences, however, it is necessary for us to carry out the reform and innovation of English teaching in order to change the ineffective way of English teaching. In this paper, three schema forms of schema theory are introduced into high school English reading teaching activities. It is hoped that schema theory can help students overcome difficulties in learning, improve the quality and speed of reading, stimulate their interest in … Read more →

Abstract.This paper investigates the distribution characteristics of earth pressure on circular caisson foundations in soft soil areas based on practical engineering considerations. Utilizing a three-dimensional numerical analysis model and a displacement-based method for earth pressure calculation, the lateral earth pressure on the retaining structure is examined. Adjustments are made to the distribution pattern of earth pressure on circular caisson foundations in soft soil areas. The study demonstrates that the radius of the caisson significantly influences the spatial distribution of soil pressure. … Read more →
