Heat waves have a catastrophic impact on ecosystems, economy, society and human health. Revealing the underlying physical drivers of heat waves is essential for improving extreme event forecasts and disaster prevention capabilities under climate change. Thus, this study provides an analysis of the maximum temperature, and heat wave frequency and duration during July–August in China from 1961 to 2022...
Malwares always query DNS names to locate their C&C servers and keep regular communication with them, either for fetching instructions or checking updates. Traditional works consider such regular communication as a single-cycle behavior. However we find that many malwares communicate with their C&C servers in a multi-cycle way, which makes them more like normal and evading existing defense...
It cannot reflect the real situation for analysis of flexible coupling-rotor system if the flexible coupling is viewed as shaft or directly ignored. After carefully analyzing the responses in different speed and different unbalance displacements considering the threaded coupling, the accurate threaded coupling-rotor system is established using finite element method. Meanwhile, the threaded coupling-rotor...
A computer aided system is proposed to screen and sort the non-patent literatures in this paper. It is introduced that the present situation and strategy of screening in data processing. The system here is a man-machine interactive system. First, knowledge and experience which stand for the know-how of the experts were inserted into the knowledge base, including the screening rules and principle in...
In this paper, in order to granulate target image's color feature, it needs define a unified formula of the similar degree. It suggests one kind of granule computing formula in images and image retrieval case formed by the similar degree. The Close-degree of the granule computing is applied in the calculation of images' the similar degree, which can improve the retrieval flexibility and system's functions.
The paper aims to discuss TD-SCDMA technology commercialization strategy and proposes a conceptual framework for mobile telecommunications technology commercialization process. In the framework, the mobile telecommunications technology commercialization process consists of three stages: (1) idea generation and invention, driven by customers, (2) technology innovation, driven by manufacturers and (3)...
