Recycled concrete technology plays a crucial role in the sustainable development of the concrete industry. However, its durability in cold regions remains a pressing challenge for engineers. This paper reviews domestic and international studies to summarize the performance and degradation mechanisms of recycled concrete under freeze-thaw cycles, focusing on four factors: recycled aggregate proportion, freeze-thaw cycle conditions, water-to-cement ratio, and admixtures. Evaluation systems for frost resistance of recycled concrete are also summarized. Finally, improvement measures for enhancing the frost resistance of recycled concrete are proposed, providing a theoretical basis for further research and engineering applications in this field.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322043","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}

When combined with an analysis of the average conductivity of effectively propped fractures at different locations, it becomes evident that the proppant distribution pattern becomes uneven after pulse injection. However, this pattern displays a discontinuous distribution law on the macro level. Influenced by the proppant distribution pattern, fracture conductivity exhibits significant variation at different locations. During the conventional injection process, the conductivity of fractures near the wellbore gradually decreases from proximity to distance. Conversely, the proppant phase distribution during pulse injection induces fluctuation in fracture conductivity, transitioning from proximity to distance.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139321930","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}

Optical fiber sensors offer more advantages than conventional sensors, such as light weight, small size, immune to electromagnetic interference, easily embedded in composites. Extensive applications have been reported with a few embedded technology details by Boeing and Airbus, etc. In this paper, The methods of improved optical fiber surface-bonded composites by glass cloth and epoxy resin, as well as optical fiber embedded in composites were researched. The installation of fiber and composites, composites assembly pressure adaptability on FBG sensors, influences on structure properties of composite materials due to different fiber diameters and different numbers of optical fibers by the way of microscopic interface analysis and C-san were studied. The adequate fiber embedded technology was found to obtain the most feasibility of SHM. Light intensity and wavelength of FBG sensor surface-bonded by glass cloth are affected by the structural assembly pressure. It can be seen that diameter of embedded optical fiber equal to the thickness of prepreg monolaye, the fiber embedded next to 0 degree layer, less than five fibers within a 25mm width composite unit have little impact on composite structure. Then, 12 FBG sensors were embedded in a typical aircraft structure, a carbon fiber enhanced stiffened composite plate with length 600 mm and width 600 mm, to detect position and energy of external impact load by a mathematical analysis method, cross correlation algorithm. Finally, suggestions on future study are listed from four aspects, co-forming technology of FBG sensor and composite skin, research on the extraction technology of optical fiber, new flexible wing testing technology and advanced fiber optical sensing technology.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322007","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}

Real car to car frontal collision is better simulated by installing deformable barrier on the load-cell wall . By the load-cell wall data, the values and distribution of vehicle frontal collision loads can be further obtained. Based on this, the full width deformable barrier tests are conducted for different structural sedans and SUV. The height index, homology index, horizontal structure interaction index(HSI), vertical structure interaction index(VSI), and minimum load-cell index are analyzed and compared. The results indicate that there is uncertainty when calculating the homology index RH and the evaluation indexes proposed by FIMCAR repeat the first step of VSI and HSI. Therefore, the height index, VSI, and HSI indexes are selected as effective indexes for evaluating the compatibility of the full width deformable barrier test.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"85 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322037","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}

There are multiple stages in the flight process of electric aircraft, as well as different failure behaviors of system components at different stages. The electric motor system is a k-out-of-n system. Therefore, it is not possible to accurately describe the electric motor system with the existing operators when using the GO-FLOW method for electric propulsion system reliability calculations. In order to solve this problem, this paper models the electric motor system using the multi-valued decision diagram method (MDD method), based on which a new operator 43 is proposed to simulate the electric motor system, and then builds the GO-FLOW model and calculates the overall reliability based on the distributed electric propulsion system schematic. The example results show that the method can calculate the reliability of the distributed electric propulsion system more realistically.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322041","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}

Genetic mutations in different subtypes of breast cancer may lead to different types of disease and have different clinical implications. Therefore, molecular typing based on the characteristics of breast cancer heterogeneity and the screening of associated genes for different subtypes of breast cancer may be able to more accurately determine the pathogenic genes of breast cancer. In this paper, we propose a weighted sample-specific network based on breast cancer subtypes to predict associated genes, named BGSSN. To better reflect the individual characteristics of patients and the importance of patient samples in different subtypes, the weight of samples is added when constructing the sample-specific network. The random walk with restart method is then utilized to predict new breast cancer-associated genes within the constructed network. By leveraging this method, the network structure can be effectively explored to identify potential gene candidates.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139321979","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}
