The data of responses from the sensor array to ethane, propane and propylene were treated by three-layer ANN with BP algorithms and PLS. The analytical results indicated that the concentration predicted with ANN is better than that with PLS. The average prediction errors for ethane, propane and propylene were 5.11%, 8.28%, 2.64%, respectively.展开更多

Through the construction of smart construction site platforms, the effectiveness and quality of on-site management work can be ensured, problems occurring in the on-site environment can be analyzed and judged in a timely manner, effective preventive and improvement measures can be formulated, and the construction effect of safety and civilization on the construction site can be strengthened. This paper mainly analyzes the application of smart site platform in municipal utilities, hoping to provide reference for the future development of the platform.展开更多

In order to greatly improve the quality and speed of power transportation in power supply and distribution system, advanced electrical automation technology is indispensable, which can effectively avoid omissions and deviations caused by man-made operation of power supply and distribution system, further alleviate the operating pressure of staff, and avoid unnecessary cost consumption on the basis of ensuring efficient operation of power supply and distribution system. In this paper, the related application functions of electrical automation technology are discussed, and the specific application contents of electrical automation technology in power supply and distribution system are analyzed.展开更多

In order to better carry out the construction of garden projects and guarantee the ultimate quality and effect of garden construction, in the actual construction stage, it is necessary to comprehensively manage the construction, consider the key elements and mitigation in the construction, and strengthen the attention and improvement of various construction problems. Judging from the current construction situation, it is necessary to make professional selection of pavement materials and strengthen the application of brand-new construction techniques in the construction of garden projects, so as to ensure the environmental protection and energy conservation of the construction, and on a certain basis, to strengthen the effect and quality of garden pavement construction. This paper mainly analyzes the application of new materials and techniques for pavement of garden roads in garden projects, hoping to improve the aesthetic and rationality of garden projects.展开更多

However, in the stage of garden engineering construction, some environmental pollution problems often occur. In order to improve the problems and strengthen the construction of conservation-oriented garden engineering, it is an important means to ensure the urban ecological environment. On the basis of ensuring the effect and quality of garden construction, the impact of construction on the environment is reduced. This paper mainly focuses on the research and analysis of the application of ecological measures in conservation-oriented garden projects, hoping to provide reference for the future construction and development of garden projects.展开更多

As an important part of agriculture, vegetables apply agricultural information technology in the process of vegetable growth and reproduction to promote the automation and information development of vegetable growth. Especially in the prevention and control of vegetable diseases and insect pests, has achieved certain achievements, it can be seen that the development of agricultural information has become the future development trend of agricultural industry. Based on this, the article starts with the related research of agricultural informatization, and analyzes the close relationship between agricultural informatization and the prevention and control of vegetable diseases and insect pests, in order to strengthen the prevention and control ability of vegetable diseases and insect pests.展开更多
