Lithium battery is a promising energy source that can used in power the electric motors of a battery electric vehicle or hybrid electric vehicle. However, in recent years, many serious safety accidents in electric vehicle that caused by the defect of the anode and cathode harm the industry. Therefore, we proposed a novel distance detection method, which can detect the defect of ...

Now, there are 36 million km2 of deserts on the planet, a quarter of the land area, and expanding by 60,000 km2 per year. To combat climate change and achieve the carbon peaking and carbon neutrality goals, China is engaged in afforestation. However, water scarcity, strong winds and shortcomings of current irrigation methods make afforestation a major challenge. Based on the ...

Artificial intelligence has infinite possibilities. With the continuous development of artificial intelligence, it will certainly provide great convenience to human life. In the future, artificial intelligence technology can be combined with smart homes.

BIM in the construction phase of the project information can be parameterized to ensure that the construction of the project data and information to achieve automated statistical analysis, BIM application in the construction phase, including technical disclosure, site layout, engineering calculation and so on to improve the construction project management quality and efficiency ...

This paper combines research and analysis of the internal chemical reactions of thermal runaway of lithium-ion batteries, identifies identification features that can accurately warn of thermal runaway, adopts a stepped warning strategy, incorporates corresponding automatic firefighting measures for the salient features of three different degrees of thermal runaway stages, and ...

This paper designs a smart socket based on microcontroller and WIFI module. The socket can measure the voltage information and grounding of the connected circuit, display the measurement results and voice broadcast, and the user can also view the measurement results in real time through the cell phone APP, and design a transparent waterproof box for it to enhance its waterproof ...

ZnO nanowires with semi-polar and non-polar orientations are fabricated on Si (100) substrates by low temperature chemical solution deposition. This distinctive growth is achieved by a co-effect of the seed layer templates and CBD solution. The growth mechanism is illustrated in detail and these semi-polar and non-polar ZnO/Si heterostructures show an excellent unidirectional ...

Valuable elements in lithium-ion batteries is a very significant secondary resource. Based on the recovery and recycling of the spent all-solid-state lithium-ion batteries in the future, we explore extracting valuable lanthanum, zirconium, and lithium elements from the solid electrolyte tetragonal phase LLZO by the leaching with the dilute sulfuric, and then by precipitation ...

Human activity recognition (HAR) is a technique that somehow senses the human activities, analyzes the relevant information, and identifies the corresponding behaviors mode. This text introduces a kind of human physical activity recognition system based on frequency features.

With the development of China, more and more foreigners are learning Chinese, and the post-epidemic period has brought the “Internet + Education” to a climax. This app combines “Chinese + vocational” education, including a multilingual HSK learning resource area and a “skills” community, and is an app that helps overseas Chinese learners to refine their vocational skills and HSK level.
