Drawing on journal articles indexed in CNKI and the Web of Science Core Collection, this study conducts a systematic review and comparative analysis of Chinese and international research on AI-empowered foreign language and translation teaching. Specifically, 104 Chinese literature pieces published between 2020 and 2025, and 200 English literature pieces published between 2006 and 2025 were included in the survey. By adopting bibliometric methods and knowledge mapping with CiteSpace, the study e...

The purpose of this paper is to introduce a nano-topological space via graph theory which depends on a neighborhood between the vertices based on undirected graph with example. The Concept of Continuity was generalized via graph in order to obtain more of characterization which is application in the graph, we also introduced the concept of nano-dense via graph theory with an example and theorem. At last the concept of homeomorphism was introduced with some examples and theorem.

With the large-scale application of industrial robots, the safety problems caused by the sudden failures of industrial robots occur from time to time. Traditional fault diagnosis methods based on data analysis have several problems, such as the sensor data are disturbed by the external environment, the communication protocols for different types of robots are complex and not unified, the monitoring systems embedded in the execution systems affect each other, and so on. In this paper, we propose ...

In order to improve the visual effect of aerial images in foggy weather, a Retinex defogging algorithm combining dark channel priors is proposed to solve the phenomenon of insufficient defogging and over-enhancement of aerial defogging in Reinex defogging. First, the foggy original image is decomposed into foggy incident light components and foggy reflected light components by Retinex theory. Then, the principle of foggy image degradation is analyzed by an atmospheric scattering model, and the d...
