In recent years, the Internet of Things technology has developed rapidly. The main monitoring method of the Internet of Things is to realize its functions through the nodes of the sensor. The monitoring network of the Internet of Things transmits the monitoring data back to the database for further analysis through the computer and mobile phone platform. More detailed management and arrangement are also important for energy conservation and emission reduction. The continuous development of Internet of Things technology is, to a certain extent, the premise and foundation of agricultural development, and the ultimate goal and the biggest trend of China's agricultural development. This paper outlines the application scope of Internet of Things technology, studies the framework model of agricultural internet of things and its model prediction, and proposes the practical application of Internet of Things technology in agricultural production by studying the impact of Internet of Things technology on modern agriculture.

Considering of the advantages of low temperature sintering of nano-silver paste, compared with other lead-free solders, low temperature sintering of nano-silver paste has been applied in chip packaging. Someone conducted in-depth research on the tensile behavior of nano-silver paste of low temperature sintering and test on the Dynamic Mechanical Analyzer (DMA), some of the sintered sliver films under different temperature decrease with increasing temperature or with decreasing strain rate. In this study, Anand viscoplastic constitutive model was adopted, and ANSYS software was used to simulate the hot cycle load of the chip and the conjunctiva of nano-silver paste. The simulation results show that the plastic strain accumulation occurred in the nano-silver paste bond layer during the temperature cyclic loading process, which is the main reason that may cause the failure of chip connection..

Able deployable articulated mast is a deployable support arm which has been used in the space field as the positioning or support structure on the spacecraft. Due to the long arm length and accurate position requirements, the reasonable modal value of the mast has a critical impact on its operational stability. In this paper, a 60m-long mast is taken to study the influence parameters of the first mode. Firstly, the key parameters of the mast are extracted. Then, using the parameterized system established by VB, the APDL language of ANSYS is called to carry out the simulation solution. The actual modal value of 6-span mast is measured through experiments, and ANSYS analysis is used to determine stiffness value of spherical joint, so the relationship between stiffness of spherical joint and pre-tension of stay cable is concluded. The effect of the pre-tension on the first mode of the mast is studied by adjusting the value of the pretension of the cable.

Different from traditional packaging materials, nano-silver has better low-temperature sintering characteristics, which meets the requirements of lead-free green environment protection, preparation of nano-silver slurry, low temperature sintering mechanism, and the influence of temperature, time and temperature. The sintering mechanism of nano-silver slurry was expounded. Citrate as a protective layer played a stabilizing role on the surface of nano-particles. The void fraction of nano-silver slurry during low temperature sintering was reviewed. The effect of void fraction on sintering process and the effect of grain size on sintering process were discussed.

Researching on consumers' satisfaction with online Tibetan characteristic agricultural products can help e-commerce entreprises grasp consumers' product cognition dynamics, adjust their management tactics in time and enhance the ability of dealing with the market emergency. Taking the example of highland barley rice, the paper collects 1047 data on consumer comments from the official flagship store of Tiancijingke foods in Jingdong Mall, and apply the ROSTCM6 system to analyze the word frequency statistics, briefly developing an evaluation index system of consumers' satisfaction with highland barley rice. Through the AHP-entropy weight method, it has been quantitatively found that the influence degree of five indicators on consumers' satisfaction with highland barley rice is decreasing successively in order of external packaging, processing quality, logistics distribution, performance perception, and selling price.

One reason why deep neural networks require lots of data is that most current training methods are only driven by the task goal information. We propose a novel instructor which can guide networks to learn useful abstraction. Since the instructor provides additional learning power, the efficiency of data is significantly improved. To get appropriate instructor, we design a generative instructor mechanism which supports learning an instructor generator from multiple tasks. The generator can generate the corresponding instructor for different tasks by using fast weights. Experiment results demonstrate the efficiency and robustness of the generated instructor. Meanwhile, our generator also shows the property relating to continuous learning.

The refinement and rationalization of urban design has become an important trend of restructuring and development during the crucial stage of China's urban transformation. At the same time, big data technology is developing rapidly, with the availability of various types of high-precision data being gradually increased. The combination of big data and urban design plays an important role in the urban design of transition period. This paper describes the design of urban education system under the big data platform. With the traditional teaching model, which include four stage (research, topic, design and expression), big data technologies are divided into four aspects to consider how to apply the big data to the teaching of urban design. Specifically summarized: big data "accelerate" researching, big data "secondary" analysis, big data "enhanced" design and big data of "optimization" expression. The aim of this research is to let the traditional teaching system and cutting-edge technology of large data collide with each other fusion, which can not only enrich the existing education system, but also establish a complete technical structure. On this basis, it can help students establish and improve the construction, and the ability to learn new technologies, to promote the progress of urban design techniques.

In the rapidly changing world economy, big data and artificial intelligence listed companies may be the future industrial giants. The main body of such enterprises is the emerging technology industry. Innovation represents the theme of today's world development. To innovate, the first thing is to enhance one's own scientific and technological capabilities, and increased R&D investment is the key to innovative development of such enterprises. The government has become the leading force in the national innovation system. The government's R&D investment, as an important means and method for the government to lead the national innovation system, is attracting more and more attention. Meanwhile, as the key leader grasping enterprise direction, executives play a decisive role in the development decision of enterprises. The executives of big data and artificial intelligence listed companies in China must realize that the core of development is independent innovation. It is especially of practical significance and research value to study the relationship between executive incentives of big data and artificial intelligence listed companies, government technology subsidies and innovation performance, and propose corresponding suggestions for the future development direction of new economy.
