Hygrothermal Treatment

Abstract The article discusses one of the directions of the transition of agricultural production in Russia to the sixth technological order based on the introduction of nanotechnology in the field of hygrothermal effects on grain crops. The features of hygrothermal action on grain under vacuum conditions are presented. The distinctive features of such processing as nanotechnology are substantiated. Based on the method of similarity in the functioning of technical systems for vacuum-capillary processes of humidification, drying, and wet-heat treatment, generalized similarity criteria are obtained, their numerical values are determined, and generalized criterion dependences of the intensity of the processes under consideration on the processing parameters are obtained. The implementation of this method made it possible to quantitatively describe the processes of vacuum capillary hygrothermal treatment of grain, to assign processing parameters and control them.

The Impact

In this paper, the pulse-induced acoustic sound in laser cutting is collected, and the data processing is performed with wavelet denoising and time-frequncy analyzing. The impact of laser processing parameters on the acoustic signal is discussed; and further analysis of the effect of cutting speed is conducted. The corresponding relationship between the best velocity and the maximum time-frequency energy density is got; also the plan of adaptive control in laser cutting is designed. The results in this paper can provide important parameters for adaptive control of laser cutting.

Time management is the ability to plan and control how a person spends his hours in order to achieve his goals effectively. This involves organizing time between different areas of life, from work, household tasks, social life, and hobbies. Time always passes and we cannot control it, but time management is by organizing events in your life in proportion to time. You may often want to get more time in your day, but you only have 24 hours, 1440 minutes, or 86,400 seconds each day. How long can someone invest Time has acquired its importance for a person, as it represents an important dynamic and mobile dimension in his life that he cannot control, and because it is the vessel that embraces all human interactions and products, and because it is life itself, and that life is the amount of time that a person lives from birth until his death. Therefore, many specialists consider time as the most important component of life, and the most important resource available to humans in life, due to its unique and distinctive features. Because of the importance of time for humans, the ancient civilizations and the various monotheistic religions varied in their interest in it, but during research findings that there are important to record a precedent in order to take advantage of each part of the time, its parts to implement the righteous and purposeful workers that benefit them with good and benefit in the world and the hereafter, and warned them against wasting it and this is clearly manifested in many of the evidence included in the recommendation and result in part.

Agricultural mechanization has become the main mode of agricultural production and represents the development direction of modern agriculture. The amount of data generated in the agricultural production process is extremely huge, so it is necessary to introduce the concept and analysis method of big data. Combining agricultural robots with big data can improve the performance and application effect of robots. This paper combines big data, WLAN technology and robot technology to realize man-machine remote cooperation platform. This gives full play to the advantages that people are good at object recognition and robots are good at execution, and improves the fruit picking efficiency. The target fruit positioning and recognition system aided by machine vision is adopted to realize the accurate positioning of the fruit to be picked. Design of LFM control signal fitting based on big data clustering. In order to verify the feasibility of the scheme, taking the tomato picking robot as an example, the communication error and control accuracy using big data and WIFI (Wireless Fidelity) technology were tested, and the positioning and navigation efficiency with and without remote monitoring system was compared. Test results show that using big data and WIFI remote monitoring technology can effectively improve the efficiency and accuracy of positioning and navigation of remote operating system, which is of great significance for the design of automatic control system of picking robot.

In the thermal processing of metal materials, the performance of thematerial is more stable, and the heat-treated materials are processed into parts to make the performance more excellent and more in line with the performance requirements of mechanical parts. However, in thermal processing, metal materials are prone to problems, such as deformation, deformation of the appearance of metal materials, and fatal effects on the processing of mechanical parts. Therefore, this paper focuses on solving the causes of deformation in the thermal processing of metal materials, as well as solutions to improve the problems in the processing of metal materials.

Severe frost usually has adverse impacts on agricultural production, resulting in crop freeze injury, poor crop yield, and crop quality reduction. Timely and accurate detection of frost plays an important role in cold damage warnings, prevention, and control. Current frost detection methods mostly use physical properties such as light, electricity, and heat, or the judge and quantify using environmental factors such as temperature and wind speed. However, it is difficult to detect and accurately identify the frosting phenomenon in real time during field trials because of the complex environment, different plant types, and interference by many factors during observation. To provide an overview of the analytical tools for scientists, researchers, and product developers, a review and comparative analysis of the available literature on frost mechanisms, correlations, and characteristics are presented in this study. First, the mechanisms of the frost formation process, frost level, and the significance of detection, are introduced. Then, the methods and techniques used to measure frost on plant surfaces are synthetically classified and further compared. Moreover, the key points and difficulties are summarized and discussed. Finally, some constructive methods of frost detection are proposed to improve the frost detection process.
