Abstract.Ecological waterway construction requires coordination and unity with natural ecology in the process of waterway construction, realize green development, and form a benign interactive construction and development model, which is in line with the concept of ecological society construction in the new period of our country. This paper makes an in-depth study of the background, research status, related methods and key technologies of the ecological waterway, and puts forward several questions according to the current situation, hoping to provide help for the relevant personnel and attract … Read more →

Abstract.Smart home provides people with a more convenient and intelligent way of living and it is one of the most widely used application of Internet of Things (IoT). However, building a smart home laboratory for students to visit and learn is labor intensive and time consuming. In order to meet the demand of experimental teaching in higher education, this paper designed and developed a Virtual Simulation Experimental Platform (VSEP) for smart home. Firstly, we introduced goals, platform architecture and functional modules of the system. Then, the development process was discussed. Specifically, the … Read more →

Abstract.The formation of fissile nuclei through breeding conversion is a hot topic in academic research, as it provides a continuous source of nuclear fuel for nuclear reactors. Fast neutron reactors, which have been extensively studied, use natural uranium or low-enriched uranium as the nuclear fuel, achieving burning after uranium-plutonium conversion. Thorium, as another potential fissile fuel, can theoretically be converted into nuclear reactor fuel through the thorium-uranium cycle. In this study, the physical evolution process of nuclear fuel in a specific core parameter is simulated using the … Read more →

Abstract.Study the front lighting system of the Volkswagen Magotan B8L model, analyze the composition and control principle of high beam, low beam, and side marker lights in the front lighting system. Introduce typical fault cases of high beam, low beam, and side marker lights, analyze fault phenomena, conduct fault diagnosis, and achieve fault elimination. Read more →

Abstract.Under the action of cyclic dynamic loads caused by earthquakes, the sandy soil foundation will liquefy, which may easily lead to damage to the pile foundation. For example, the soil liquefaction will cause pile foundation subsidence, the failure of the connection between pile cap and cap, and the beam drop caused by pile foundation moving sideways with soil. There are many influencing factors of foundation liquefaction, and the influence of many factors on foundation liquefaction is highly nonlinear. The author analyzes the liquefaction principle of sandy soil foundation and combines the … Read more →

Abstract.There are studies on the impact of agricultural technology progress on rural revitalization. Domestic scholars have initially studied the relationship between the two. Agricultural technological progress has a significant impact on rural revitalization, and rural revitalization is a nonlinear system. This paper will use the threshold variable model and the DLNM nonlinear lag model to deeply test the nonlinear impact of agricultural technological progress on rural revitalization, and at the same time explore whether there is a lagged impact, explore the path of rural revitalization using the … Read more →

Abstract.In order to study the internal cycle characteristics of glutenite reservoirs, this study conducted high-resolution sequence division of glutenite based on INPEFA technology and wavelet transform technology. In this paper, the basic principles of INPEFA technology and wavelet transform technology are introduced in detail, and the differences and advantages and disadvantages of the two methods in high-resolution sequence division are compared. Taking Jilantai oilfield as an example, combined with INPEFA technology and wavelet transform technology, INPEFA processing and wavelet processing are … Read more →
