Abstract :

In order to improve the quality of the porous asphalt pavement in seasonal freezing areas and reduce the freeze-thaw damage of the pavement, the modified porous asphalt mixture with glass fiber, diatomite and old asphalt pavement materials are employed to improve the performance. The changes in compressive strength, porosity, and strain of porous asphalt mixtures with different material contents after freeze-thaw cycles are analyzed by considering the influence of different materials and different material contents on the water stability of porous asphalt mixtures. Based on the theory of damage mechanics, the compressive strength is used as an index to represent damage variables, and the evolution of freeze-thaw damage of modified porous asphalt mixtures is also studied. Based on the CT non-destructive testing and digital image processing technology, the changes in the number of air voids and air void area of the glass fiber porous asphalt mixture before and after freezing-thawing are analyzed. The test results show that the compressive strength of the mixture decreases with the increase of the number of freeze-thaw cycles, and the void ratio and strain show an increasing trend. Four porous asphalt mixtures with 0.7% glass fiber content, 15% old asphalt pavement material content, 25% diatomite content and 15% old asphalt pavement material and 20% diatomite content present the best water stability. The modification effect of glass fiber is the best. Mixing glass fiber, 15% diatomite and 15% old asphalt pavement material may reduce the freeze-thaw damage of porous asphalt mixtures. However the recycled porous asphalt mixtures containing diatomite have more serious damage and have higher strength in the early stage of damage, which are more suitable for short-term frozen soil areas. Compared with recycled porous asphalt mixtures containing diatomite, the porous asphalt mixture containing glass fiber, recycled porous asphalt mixture and porous asphalt mixture containing diatomite have a longer rapid damage period, a shorter damage stability period and a shorter damage evolving period. The number of air voids in the sample increases and the average single air void area decreases with a lower glass fiber content, while the sample with a higher glass fiber content has the opposite effect.

Abstract :

River flow is affected by boundary shear stress, and too large boundary shear stress will lead to erosion and reduce the stability of river banks, and cause river morphology changes by affecting sediment deposition and transport. To study the shear stress of river boundary is equivalent to the study of flow characteristics in river. Because there are too many complex factors affecting the boundary shear stress in rivers, a two-dimensional rectangular straight open channel flow model was established by numerical software after removing all factors, and the laboratory experiments were carried out on the rectangular straight open channel model by using similarity theory. Firstly, numerical simulation was carried out for flows in uniform straight channels of 5 different scales. Since the stage-discharge relation obtained from the simulation results is highly consistent with the stage-discharge relation deduced by Manning formula, it can be considered that the parameters simulated by the model are true and reliable. In the case of non-uniform flow, through the concepts of under-uniform flow and super-uniform flow, 9 cases of straight open channels under different discharges were simulated in this paper. The momentum theorem was used to analyze the force at 101 points with the same spacing in the center of the non-uniform straight path. The average value of shear stress was taken between every two points, and then the resistance of all points was summed up to approximate the integral of the river bed resistance, which will greatly reduce the influence of the error caused by uncertain factors such as stage fluctuation. A general formula of bed shear stress was derived, which showed that the bed shear stress could be calculated by the water depth h, flow velocity u and Manning roughness coefficient n, regardless of whether the flow of rectangular open channel is uniform or not. To verify the new formula, the new formula was compared to four existing formulas, and the results showed that the new formula conformed to the momentum theorem and had physical significance. The research result is simpler than the traditional methods and can provide a faster algorithm in required calculations.bm

Abstract :

In order to relieve the alarm fatigue of security analysts and improve the security operation efficiency, an attacker IP analysis system based on the Ensemble-based Local Outlier Factor algorithm (EBLOF) was proposed in this paper. Firstly, normalized network security alarm logs were extracted and merged, and then the feature engineering was constructed from the attribute dimension and attack behavior dimension of attacker IP. Secondly, inspired by the idea of ensemble learning and traditional LOF anomaly detection algorithm, a robust EBLOF algorithm of finding high-threat attacker IP was constructed in the system. Thirdly, a set of online learning architecture was built by the system, aiming to solve the problem that the machine learning model was difficultly updated online. Through the batch real-time learning technology, the learning architectures ensure that the learning model can be updated online from the system architecture level rather than the algorithm level. Finally, the EBLOF algorithm of this paper was trained on the public anomaly detection data set ODD. The experimental results showed a fact that the algorithm has better robustness than the naive LOF algorithm under different data distributions. The system proposed in the paper was applied in real attack and defense scenarios. Its effectiveness and feasibility were verified by comparing with security operation analysts

Abstract :

CCTS-based solar cells show promising performance in the realm of sunlight-based energy production in this study. Optimizing the buffer layer remains a barrier to improving the efficacy of CCTS-based solar cells. The initial structure is made up of a CCTS absorber layer, a ZnO resistive layer, an AZO transport conducting layer, and a window layer, as well as different buffer layers (CdS, ZnS, and ZnSe) to find the best buffer layer. The second structure is made up of a CCTS absorber layer, a ZnO resistive layer, an AZO transport conductive layer, a window layer, and different buffer layers (CdS, ZnS, and ZnSe) to find the best buffer layer. The second structure consists of the same layers as the first structure, minus the resistive layer ZnO, while the third structure consists of the same layers, minus the window layer AZO. The solar cell in this structure's open circuit (Voc), short circuit current (Jsc), fill factor (FF), and conversion efficiency (PCE) revealed that the first structure has good agreement, and that these buffer layers were used to investigate the effect of buffer thickness as alternative buffer layers. Among these three buffers, cadmium sulphide CdS) is preferable over Zns and ZnSe, and after improving the initial structure, the power conversion efficiency (PCE) was 13.47% for buffer Cds, 13.46%. The simulation showed that for structure MO / CCTS /(CdS)/ZnO / AZO at (3100) nm of absorber layer (CCTS), 40 nm of buffer layer (cds), 10 nm of resistive layer (ZnO), and 60 nm of AZO performs the best for (Voc = 0.573 V, Jsc = 30.344 mAcm-2, FF = 72.57 %, and PCE = 13.91%).

Abstract :

The effect of ethanol on diesel engine performance using B30 fuel has been investigated, namely a mixture of 30% calophyllum inophyllum biodiesel and 70% petrodiesel. The ethanol concentration mixed to B30 was 10% and 20% vol/vol. The experiment was conducted on a single-cylinder four-stroke diesel engine with a natural air system and joined with a generator that functioned as a dynamometer. The test was applied three times to the machine for each load, involving 0, 200, 400, 600, and 800W at a constant rotation speed of 2000 rpm. The experiment reveals that the consistent engine speed method and lamp load produce the same torque (Nm) and effectiveness power (kW) between fuels, impacted by the governor's mechanism. The 20% ethanol (B30E20) has the highest effective thermal efficiency of 28.41% and effectiveness fuel consumption of 0.46 kg/kWh. The addition of 20% ethanol reduced exhaust emissions of carbon monoxide and hydrocarbons up to 0.09% and 27.33 ppm. However, there was an exhaust emissions increase of carbon dioxide up to 8.0%. The exhaust emissions increase of carbon dioxide cannot be considered as a negative consequence because it can be reused (consumption) in the photosynthesis process raw material biofuels.
