Methods for determining moisture content can be divided into two types: direct measurement and indirect measurement. Among indirect measurements, nuclear magnetic resonance, infrared radiation and radio waves are the most commonly used measurement methods. At microwave frequencies, moisture will be polarized and oscillate, and the transmitted microwaves will be scattered, projected, ...

With the rapid development of UAV technology and the promotion of low-altitude economy, UAV applications are penetrating throughout the industry [1], and collaborative mission execution has become a mainstream trend. This paper focuses on the task allocation and path planning problems in multi-UAV collaborative mission planning.

Flow experience can promote person to produce an important aspect of happiness. A lot of study on flow experience can give a person with great pleasure and improve the quality of individual life. Physical exercise on negative psychological improvement has received a lot of empirical support, the rise of positive psychology, puts forward a new thinking for physical exercise, ...

The development of the cell seed feeder is important for the world seed industry, it can improve the breeding efficiency, shorten the breeding cycle and promote the development of the breeding industry. In order to promote the mechanization process of community breeding in the world, it is necessary to combine the requirements of breeding agronomy and work. In this paper, we ...

Ferrite absorbing metamaterials designed with metamaterial structures can effectively broaden the absorption bandwidth of electromagnetic waves. The current mainstream approach is to compound ferrite with other materials to produce ferrite absorbing metamaterials with better performance.

Promoting the construction of the Belt and Road is a major initiative of China's opening up to the outside world at a new stage of economic development, which is of great significance to both China and the countries along the Belt and Road. Taking investment projects along the Belt and Road as an example, this paper explains the current situation of investment projects along the ...

For environmental purposes, namely resource conservation, it is proposed to install a rainwater gathering system. You can collect rainwater by means of the system and use this water for the needs of the trolley fleet (washing of rolling stock). This system reservoirs can be also used for storage of excess filtered water.

In order to solve the problem of accurate navigation of mobile robots in dynamic indoor environment, a semi-direct RGB-D visual SLAM (Simultaneous Localization and Mapping) algorithm based on motion detection algorithm is proposed. The algorithm is mainly divided into three parts: motion detection, camera positioning and dense map construction based on TSDF (Truncated Signature ...

The composition of the glass scintillation materials was elaborated. The effects of rare earth ions upon spectral and luminescent properties of the glasses and glass ceramics were established.

The key to mechanized harvest of forest and fruit crops is efficient and low-loss picking. The existing machinery is mainly vibrating picking machinery. In order to prevent the resonance phenomenon between the machine and the fruit tree from damaging the trunk during picking, it is necessary to use ANSYS and ADAMS software to conduct dynamic simulation of the picking process.
