The study used yellow soil as the main experimental material, combined with additives such as cement, sodium sulfate, and ethylene glycol, successfully developing a controllable low-strength fluid material, namely, yellow soil slurry. Based on this, with steel bars as reinforcing material and yellow soil slurry as grouting material and slope protection layer, indoor scaled model tests were conducted relying on the similarity principle, using the yellow soil from a roadbed slope project in Lanzhou. Using slope top settlement and foot bulge as mechanical response indicators, the study investigated the effects of slope gradient, soil nail length, angle, and spacing on the stability and bearing capacity of roadbed slopes. Experimental results indicate that indoor model tests found that the gentler the slope, the higher the stability, and soil nail length and density can enhance the bearing capacity of the roadbed; the reinforcement effect on the roadbed slope is most significant when the angle between the soil nail and the horizontal direction is around 10°. The study results are of reference significance for the application of yellow soil slurry in roadbed slope engineering.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":"20 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139185223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bubbles are generated through underwater discharge, and the generating device is placed horizontally or vertically below the ice plate, and the experimental phenomenon is observed through an ultra-high-speed camera. Firstly, the motion characteristics and ice breaking ability of two horizontal bubbles under an unperforated ice block were demonstrated. Then, the motion characteristics of two horizontal bubbles and two vertical bubbles under a porous ice block, the breaking effect of the ice block, and the water mound phenomenon on the free surface were observed. The experiment observed unique bubble behavior, including bubble fusion, bubble collapse, and oblique jet, as well as the influence of bubble-bubble and bubble-ice interactions on the morphology evolution and ice breaking effect of bubbles. The results indicate that the ice breaking effect of the interaction between bubbles and perforated ice plates is weaker than that of non-perforated ice plates, which may be more helpful for subsequent bubble ice breaking research.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":"17 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139184961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking a two story, three span, and shallow buried subway station as the research object, a two-dimensional finite element analysis model of soil structure underground in a typical engineering site was established using ANSYS. Ten earthquake records were selected from PEER as input, and the structural seismic fragility analysis method based on incremental dynamic analysis (IDA) method was introduced into the subway station structure. The maximum story drift angle was used as the structural damage index, and three typical seismic intensity measures were selected, the exploration is conducted on the seismic intensity measures applicable to shallow buried subway stations and the variation pattern of seismic response of subway stations with increasing seismic amplitude. The seismic fragility curve of shallow buried subway station structures is established to obtain the failure probability of the structure at different seismic intensity levels. The analysis results indicate that for shallow buried subway stations, PGA is the most suitable seismic intensity measure, and the comparison with existing empirical fragility curves shows that the vulnerability analysis method is feasible and can quantitatively provide the failure probability of structures at different performance levels, providing reference for seismic design of underground structures.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139267956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, escalating demands, coupled with climate change, have given rise to significant water scarcity in numerous areas, including the Yellow River Delta (YRD) in China. This study aims to characterize the hydrochemical composition and stable isotopes (δ2H and δ18O) of groundwater in YRD and identify spatial clustering patterns using combined Hierarchical Cluster Analysis (HCA) and Discriminant Analysis (DA). Comprehensive analyses were conducted on the major ions (i.e., K+, Na+, Ca2+, Mg2+, Cl-, SO42-, and HCO3-), water quality indicators (i.e., pH, electrical conductivity (EC), and oxidation-reduction potential (ORP)) and isotopic composition of groundwater samples. Applying HCA on a collection of 38 water samples, the study delineated six distinct clusters, each bearing unique hydrochemical characteristics. DA was used to establish a discriminant model, achieving a classification accuracy of 80% for new groundwater samples. The study underscores that there are localized variations in the hydrochemical characteristics of groundwater in YRD, attributed to different geological conditions and anthropogenic influences. Such insights are instrumental in crafting effective strategies for water resource management, environmental conservation, and sustainable development in YRD and other analogous regions confronted with groundwater challenges.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139290459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The difference of pupil diameter under different color combinations showed that background color had a significant effect on visual fatigue. In addition, black background color can lead to the lowest degree of visual fatigue, followed by brown background color. Moreover, blue background color was the most likely to cause visual fatigue. The subjective report data showed that the visual afterimage color was related to the foreground and background color combination. In the combination of background color and foreground color, the ratio of visual afterimage color and background color is the highest, followed by the foreground color, and the complementary color of foreground color or background color.

The reaction produces a wide variety of products, of which C2+ products such as ethylene, ethanol and propanol have higher energy density and added value compared to C1+ products such as carbon monoxide and formic acid [1]. Electrochemical reduction of CO2 is carried out using a gas diffusion electrolytic cell, which has many advantages: 1. small size, easy operation, close electrode distance, etc., which can effectively improve the mass transfer efficiency between gas and liquid; 2. the advantage of close electrode distance is low potential and less electrolyte consumption; 3. the reactor is easy to install and dismantle, the reaction system is well-closed and does not leak; the electrolyte is circulated outside the body, and the flow rate is adjusted by a peristaltic pump, which is more convenient and easy to control. At present, a new type of catalyst preparation has been completed and has completed the effect of the test, the catalyst is by the copper iodide (CuI) and 4,4-bipyridine coordination reaction two obtained by the ratio of the amount of different substances of the two mixed as well as the reaction of different time to obtain different coordination form of the catalyst, and the effect of the test, that is, the catalyst mixed with organic solvents are sprayed together with the carbon paper, clamped into the electrolytic cell, the electrolyte is analyzed using various instruments. Various instruments were used to analyze the composition of the electrolyte to derive the percentage of product. Through the test, it was found that the color of the catalyst gradually became darker with the prolongation of the reaction time, and the color of the catalyst gradually became darker with the increase of the proportion of 4,4-bipyridine in the reactants. The catalytic effect of the darker catalysts was significantly better than that of the lighter catalysts, with the percentage of C2+ products such as ethylene and ethanol increasing by 10%-15%.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139290152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The data were obtained from the data set of Question C of the 2022 Gaoxueshe Cup National University Student Mathematical Modeling Competition. After eliminating the invalid data, analytical methods such as association rule analysis, factor analysis, cluster analysis, and algorithms such as Apriori and K-means++ were used for problem solving. Results: A total of 56 glass artifacts and 56 artifact sampling sites were included in the study, and the main findings were as follows: the relationship between the weathering of the surface of glass objects and their glass type, decoration, and color under the two-, three-, and four-correlation rules; the classification of glass objects into high-potassium or lead-barium glass based on the five compositional categories (SiO2, PbO, CaO, Fe2O3, and K2O); and the clustered dendrograms. The most homogeneous classification of high-potassium or lead-barium glass into each of the three subcategories was based on magnesium oxide and aluminum oxide, whose content varied considerably before and after the weathering process; and finally, changes in the chemical compositional correlation between the different categories were also analyzed.
