This study proposes a new approach to tackle the challenge of detecting hidden hollows in urban areas. The approach utilizes geophysical investigations using soil stress waves excited by subway tunnel vibrations to examine void defects in the soil layers above. A shaker excited concrete plates to generate the necessary stress waves required for detecting vacancy defects. The results showed that the amplitude of the stress wave signals in both the time and frequency domain significantly attenuated after passing through void defects. There were significant differences in wave impedance at the boundaries of these voids. Wave field propagation contour maps, obtained using laser Doppler vibrometers (LDVs), visually demonstrated the propagation of soil stress waves at the boundaries of void defects. Reflected waves exhibit increased strength with larger void dimensions, while diffracted waves at the soil’s end weaken. The energy distribution contour maps in the time domain provided an intuitive indication of the presence, horizontal projection position, and size of the void defects. Sensitivity coefficients ((omega)), statistical feature indicators such as root-mean-square deviation coefficients ((RMSD)), and wavelet packet energy ratio deviation coefficients ((E_{RVD})) were established to quantitatively characterize the size of void defects from different perspectives. The preliminary findings of this study have verified the feasibility and scientific validity of utilizing soil stress waves generated by subway vibrations for the detection of void defects.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"13 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current study, a small-scale jet grouting device has been used to create 47 small-scale columns in dry and wet (20% moisture content) sand to investigate the effects of the soil moisture content on the diameter, uniaxial compressive strength (UCS), and the treatment efficiency. The columns were constructed using different injection times, rotational speeds of 10 and 25 rpm, and soil relative densities of 5% and 95% to assess the comparative influence of the moisture content on the effectiveness of other parameters. The results demonstrated that the initial soil moisture had the most significant effect on the column diameter. In sand with a 20% moisture content, the column diameter increased an average of 63% and 87% in loose and dense sand, respectively, compared to dry sand. However, an increase in the injection time in wet sand caused a significant decrease in the treatment efficiency. A 60% decrease in the rotational speed from 25 to 10 rpm had a greater effect on increasing the diameter in dry sand than doubling the injection time. The relative density had a much smaller effect on the column diameter created in wet sand than in dry sand. The high cement-to-soil ratio of the columns increased the UCS of the core samples and eliminated the effect of the aforementioned parameters on the UCS.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"25 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a gap in the literature on the high-temperature wear properties of Inconel 718. The aging process determines the service life and working conditions of the alloy. This study aims to reveal the effects of various aging heat treatments on the room and high-temperature wear properties of Inconel 718. The aging conditions were selected as non-aged, solution aged (SA), conventionally aged (CA), overaged (OA) and furnace-controlled aged (FCA). Cylindrical samples were machined for 500 m, using a Si3N4 ball at room temperature and 400 °C. The surfaces of the samples were smoothed by turning. FCA was performed in a controlled atmosphere furnace. The heating and cooling rates of FCA were 10 min/°C. Ar was selected as the shielding gas. The rapid cooling stages of SA, CA and OA were performed by quenching in water. FCA refined the microstructure and enhanced the wear resistance. SA resulted in a rigid microstructure, abrasive wear was dominant. EA led to an increase in the Laves phase ratio, which was identified by X-ray diffraction analyses. Optical microscope and scanning electron microscope (SEM) images of the microstructures and worn surfaces were correlated with the microhardness scores to accurately define the wear properties. The precipitations were identified by energy-dispersive X-ray spectrum application that is combined to SEM. The experimental evidence from this work clarified the predominant wear mechanisms due to microstructure and phase evolution.

The KRuBr3, RbRuBr3, and CsRuBr3 materials' band-structure data during the evaluation rendered it obvious that these materials exhibit an indirect semiconductor nature, with bandgap values of 1.81 eV, 1.79 eV, and 1.74 eV, respectively. The three critical elastic constants for each of these materials under inquiry were initially determined and these values were subsequently employed to assess every mechanical characteristic of the materials under study. To identify the degree of ductility, the computed Pugh's and Poisson's ratios for the KRuBr3, RbRuBr3, and CsRuBr3 materials were confirmed. The bandgap values of the explored materials lie in the range of the visible spectrum reflecting its feasibility for solar cell technology.

Due to the damage to machine components, manufacturing processes degrade over time, resulting in substandard products. Generally, statistical process control tools such as control charts aid in identifying patterns and trends indicative of process changes. This investigation delves into the effectiveness of cumulative sum control charts using the sample mean and median as plotting statistics. Run-length measurements assess performance after the charts experience linear and quadratic drifts in non-normal setups under zero- and steady-state conditions. The findings reveal that Cumulative Sum (CUSUM) charts outperform zero-state monitoring compared to steady-state monitoring. Notably, the CUSUM chart for the mean is suitable for normal and Gamma distributions, exhibiting a greater ability for drift detection under biased and unbiased Average Run Lengths. This study offers valuable insights into enhancing manufacturing quality through effectively implementing and comparing Shewhart, Exponentially Weighted Moving Average, and CUSUM charts. By evaluating their performance under various conditions and comparing them with other control chart methods, this research provides valuable guidance for industries seeking to improve process monitoring and product quality. It is essential to acknowledge that the findings are based on specific experimental conditions and may not fully capture the complexity of real-world manufacturing environments. For practical purposes, the suggested charts are also applied to real-world case studies, including air quality (focusing on five metal oxide chemistry sensors: carbon monoxide concentration, non-metonic hydrocarbons, benzene, total nitrogen oxides, and nitrogen dioxide) and maintenance data (including air temperature, rotating speed, and equipment failure).","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"25 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This type of machining is a highly coupled thermomechanical process. During machining, the tool/chip interface is the site of complex interactions between mechanical, thermal and metallurgical phenomena. The experimental study remains difficult and expensive because of the multitude of parameters involved in the cutting phenomenon, which makes the use of finite element (FE) simulations an essential approach. In this work, a thermomechanical 2D model of the orthogonal cutting process of 42CrMo4 steel was developed using Abaqus/Explicit. The objective of this work is to study the influence of cutting parameters (feed f and cutting speed Vc) on cutting forces, stress distribution and temperature. A particular interest is given to the temperature and constraints of the cutting tool compared to similar work, particularly for 42CrMo4 steel. Knowing these two answers makes it possible to calculate the wear and thus the service life of the cutting tool. The results show that cutting speed and feed rate have a significant influence on cutting force, stress and temperature in the cutting zone. A comparison of the simulated and experimental results was carried out in terms of cutting force, to verify the accuracy and reliability of the developed simulation model. It was found that the average error on the cutting force is 8.11%, which proves the relevance and reliability of the proposed numerical model.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"35 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The discrimination of fault and normal operating conditions is achieved based on the signs of reactive power at both ends of the transmission line.

The purpose of this study is to evaluate nucleated hydroxyapatite (HA) on polydopamine (PDA)-coated 3D printed PLA scaffolds, focusing on chemical composition, morphology, crystallinity, wettability, porosity, and biocompatibility via MTT assay. 3D printed PLA scaffolds were designed using computer-aided software (CAD). These scaffolds were immersed in a dopamine salt solution for 24 h to create a thin PDA layer and then placed in Simulated Body Fluid (SBF) for 5 days to stimulate apatite layer formation, observed through FE-SEM. PLA scaffolds had smooth surfaces, while PLA–PDA surfaces were different, and PLA–PDA–HA scaffolds revealed more homogeneous distribution of HA. PLA scaffolds had higher porosity (88%) and hydrophobic, whereas PLA–PDA scaffolds became hydrophilic due to the introduced amine and hydroxyl groups from the PDA coating. PLA–PDA scaffolds were amorphous, indicating reduced crystallinity, while PLA–PDA–HA displayed crystalline structure. The PLA–PDA–HA scaffolds declined most in weight loss (0.7%) due to the hydrolytic degradation of HA. In contrast the PLA–PDA scaffolds were the least degraded, with steady degradation trend lasting up to the 21st day of immersion. The PLA–PDA–HA scaffolds, with HA nucleation, exhibited the highest cell viability (145%) on day 7, emphasizing the crucial role of robust cell viability in tissue engineering. In conclusion, the PLA–PDA–HA scaffold was the most robust option due to its enhanced adhesion, biocompatibility, and potential protection against degradation.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"37 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, PV-PCM (Phase Change Material) integration is a widely used passive method to reduce and stabilize PV panel temperature. However, particularly in angled PV panels, the movement of the PCM within its container can cause uneven temperature distributions on the PV panel surface. To address this issue, this study employs a trapezoidal geometry to increase the amount of PCM and the surface area exposed to the environment in the regions where the molten PCM accumulates. Furthermore, the effects of PCM area and heat transfer coefficient to the environment on the temperature distribution of the PV panel for different trapezoidal geometries (different tilt angles and the ratio of side surfaces) were investigated. A numerical model was developed for these investigations, and this model was validated with experimental work found in the literature. The results showed that the surface temperature decreased by 5–21 K and the surface temperature uniformity improved between 10 and 44% depending on the parameter change with the use of trapezoidal geometry.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"62 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extending the network’s lifespan is challenging because of the sensors’ short battery life. However, developing appropriate charging schedules for mobile charging vehicles (MCVs) is a difficult problem. These charging schedule designs can have an influence on WRSNs overall consumption of energy and lifetime. We address the challenge of minimizing travel energy for MCVs in WRSNs. Our proposed solution includes a priority-based charging schedule that balances MCV travel time and charging time effectively. Additionally, we offer a method for selecting charging energy levels to conduct partial charges aiming to prolong the network’s lifespan. We have also incorporated the remaining lifetime of sensor nodes (SNs) as a crucial factor in mitigating the occurrence of dead SNs in the network. In this article, we partition the requested SNs into several partitions and assign an MCV to each region using the Aquila Optimization meta-heuristic approach. A heuristic-based partial charging method is proposed. We compare the outcome of our proposed technique with several other existing algorithms. The outcomes of the simulation indicate that our suggested method performs better than the others. Additionally, an analysis of variance and a post hoc analysis are carried out. We demonstrate, through comprehensive simulations and hypothesis testing, that the proposed scheme increases the number of replenished sensor nodes up to 36.36% and the charging utility up to 97.82% while decreasing the charging time and the number of dead sensor nodes up to 54.16% and 85.86%, respectively.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"13 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
