Haifeng Liu,Xiaolong Chen,Jialing Che,Ning Liu,Minghu Zhang 한국콘크리트학회 2020 International Journal of Concrete Structures and M Vol.14 No.4

Currently, fire in building is one of the most serious disasters. With the increase of basic construction items in western China, ordinary medium sand resource no longer met with the need of engineering. Compressive strength experiments of concrete produced with desert sand after elevated temperature were carried out in this paper. The effects of desert sand replacement rate (DSRR), temperature and cooling regime on the mechanical performances of concrete produced with desert sand were analyzed. XRD and SEM experiments were also conducted to study the microstructure of concrete produced with desert sand after elevated temperature. Experimental results showed that the cubic compressive strength of concrete produced with desert sand increased firstly, and then declined with temperature. Whereas, the prismatic compressive strength and elasticity modulus of concrete produced with desert sand under static compression declined with temperature. With the enhancement of DSRR, the elasticity modulus under static compression, cubic compressive strength and prismatic compressive strength of concrete produced with desert sand after elevated temperature increased firstly, and then declined, the maximum value of which was reached when DSRR amounted to 40%. Regression models were established to predict the mechanical performances of concrete produced with desert sand after elevated temperature, which were in good agreement with experimental results.

At present, the exploitation of river sand is forbidden because of the harm to the environment. The production processes of microsilica sand are complicated and the cost is high. The excellent availability of desert sand provides a practical solution for using it as the aggregate, this research used high-volume fly ash, steel fiber, PVA fiber and some or all of the Mu Us desert sand to replace the river sand to prepare the Desert-Sand-based steel-PVA hybrid Fiber Reinforced ECC (H-DSECC) that meets the performance requirements. Through the single factor test, the steel fiber replacement rate and the desert sand replacement rate were taken as the main factors, and the mechanical properties of H-DSECC were initially explored. The results show that the high steel fiber replacement rate or high desert sand replacement rate is not conducive to the realization of strain-hardening. An H-DSECC mixture containing 40% desert sand with W/B ratio of 0.29 has delivered the best properties with the tensile strain capacity of 1.467%, the tensile strength is 7.5 MPa and the cylinder compressive strength is 41.03 MPa at 28 days. Based on the measured stress-strain curves, the uniaxial tension/compression stress-strain curve equations are proposed.

Experimental Study on the Electro-osmotic Treatment of Frost Boiling Damage of Cold-Region Subgrade

Deren Liu,Jiale Yang,Shuangyang Li,Xu Wang,Shuochang Xu 대한토목학회 2022 KSCE Journal of Civil Engineering Vol.26 No.4

In cold regions, the pore water of subgrade surface soil rises sharply because ice lenses thaw in spring-thawing seasons and cannot drain out in a short time, which leads to a high water content in the thawed layer of the cold-region subgrade. Frost boiling damage of subgrade occurs frequently under repeated traffic loads and seriously affects the normal operation of the road. Based on the advantages of rapid and effective electro-osmotic drainage, a horizontal stage electro-osmotic drainage method (HSEDM) was designed to treat the frost boiling damage of cold-region subgrade. To test the engineering effectiveness of the HSEDM, a model test was carried out, in which many key indexes, such as the current intensity, effective potential, electrode corrosion, water content, shear strength and surface settlement, were closely monitored. Through the controlled trial, it indicates that the pore water was mainly driven to move from the anode to the cathode and further drained out from the slope by electric field force. At the same time, the shear strength of the frost boiling subgrade increases significantly after electro-osmotic consolidation. The experimental results provide a theoretical basis for the engineering application of the HSEDM in the treatment of frost boiling damage of cold-region subgrade.

Indicator of percolation transition in graphite oxide suspension containing cations

Liyan Liu,Jiale You,Haonan Zhu,Wei Tang 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.7

The percolation transition behavior occurs in the solid-liquid separation of graphite oxide (GO), whichchanges the system from suspension to colloid state and terminates the separation process. An indicator of percolationtransition is necessary to help control the status of GO suspension to finish the solid-liquid separation process. Theswell ratio, macroscopic appearance TEM, and rheological behavior of GO suspension were tested before and after thepercolation transition occurred in a specific interval of K+ concentration. Then, the physical properties of 1.00 g/L GOsuspension containing 0.40-0.80 g/L K+, including conductivity, thermal conductivity, viscosity, surface tension, andabsorbance were characterized. The values of these physical properties showed a sharp change in the specific interval ofK+ concentration. We calculated the first and second slope of two adjacent points of each physical property to obtain aproper percolation transition indicator. The conductivity with the second slope up to 500% was the most significantchange among these physical parameters, which can be used as an indicator of percolation transition in GO suspension. To verify the availability of the indicator, we explored the percolation transition behavior of Ca2+ and Al3+ in GOsuspension and K+ with different GO solid content, found that the conductivity is still the most significant percolationtransition indicator. The indicator obtained in this paper is reliable under varying content of GO and types of cations insuspension, which can be used to determine the percolation transition threshold during the solid-liquid separation ofGO suspension containing cations.

In this paper, we study the joint radio and computational resource allocation in the ultra-dense mobile-edge computing networks. In which, the scenario which including both computation offloading and communication service is discussed. That is, some mobile users ask for computation offloading, while the others ask for communication with the minimum communication rate requirements. We formulate the problem as a joint channel assignment, power control and computational resource allocation to minimize the offloading cost of computing offloading, with the precondition that the transmission rate of communication nodes are satisfied. Since the formulated problem is a mixed-integer nonlinear programming (MINLP), which is NP-hard. By leveraging the particular mathematical structure of the problem, i.e., the computational resource allocation variable is independent with other variables in the objective function and constraints, and then the original problem is decomposed into a computational resource allocation subproblem and a joint channel assignment and power allocation subproblem. Since the former is a convex programming, the KKT (Karush-Kuhn-Tucker) conditions can be used to find the closed optimal solution. For the latter, which is still NP-hard, is further decomposed into two subproblems, i.e., the power allocation and the channel assignment, to optimize alternatively. Finally, two heuristic algorithms are proposed, i.e., the Co-channel Equal Power allocation algorithm (CEP) and the Enhanced CEP (ECEP) algorithm to obtain the suboptimal solutions. Numerical results are presented at last to verify the performance of the proposed algorithms.

Qiu, Jialing,Lu, Xintao,Ma, Lianxiang,Hou, Chuanchuan,He, Junna,Liu, Bing,Yu, Dongyou,Lin, Gang,Xu, Jiming Asian Australasian Association of Animal Productio 2020 Animal Bioscience Vol.33 No.4

Objective: The objective of this study was to investigate the effects of low doses of organic trace minerals (iron, copper, manganese, and zinc) on productive performance, egg quality, yolk and tissue mineral retention, and fecal mineral excretion of laying hens during the late laying period. Methods: A total of 405 healthy hens (HY-Line White, 50-week-old) were randomly divided into 3 treatments, with 9 replicates per treatment and 15 birds per replicate. The dietary treatments included feeding a basal diet + inorganic trace minerals at commercial levels (CON), a basal diet + inorganic trace minerals at 1/3 commercial levels (ITM), and a basal diet + proteinated trace minerals at 1/3 commercial levels (TRT). The trial lasted for 56 days. Results: Compared to CON, ITM decreased (p<0.05) egg production, daily egg mass, albumen height, eggshell strength, yolk Fe concentration, serum alkaline phosphatase activity and total protein, and increased (p<0.05) egg loss and feed to egg ratio. Whereas with productive performance, egg quality, yolk mineral retention, and serum indices there were no differences (p>0.05) between CON and TRT. The concentrations of Fe and Mn in the tissue and tibia were changed notably in ITM relative to CON and TRT. Both ITM and TRT reduced (p<0.05) fecal mineral excretion compared to CON. Conclusion: These results indicate that dietary supplementation of low-dose organic trace minerals reduced fecal mineral excretion without negatively impacting hen performance and egg quality.

Sensorless Control of the Switched Reluctance Motor Based on the Sliding-Mode Observer

Li Xinyu,Liu Jiayu,Ge Lefei,Zhong Jixi,Huang Jiale,Zhao Yuchen,Song Shoujun 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.2

To upgrade the application of switched reluctance motors (SRMs) for more electric aircraft, this paper presents a method with sensorless control based on the flux-linkage data from the finite element method. First, a calibration strategy is employed to obtain the flux-linkage characteristics. Then, a sliding-mode observer is used to realize the sensorless control of the SRM. The proposed method only requires the flux-linkage of the SRM at aligned and unaligned rotor positions from the experiment which takes a low-measurement effort to get the rotor position and has better accuracy in position and speed estimation than the FEM. Experimental results verify the accuracy and effectiveness of the proposed method.
