Published: November 2024

Objective: This descriptive systematic review was evaluated the effectiveness of mobile applications designed to aimed to prevent suicide.
Material and Method: Within the scope of the study, open access Turkish and English articles published in online databases (Web of Science, PubMed, WİLEY, Taylor & Francis Online, Science Direct) between 2019 and August 2024 were reviewed. Randomized controlled trials on mobile applications whose role in preventing suicide was clearly stated in the articles were included in the study.
Results: As a result of the screening, seven studies that met the inclusion criteria were included in this study. In four of the included studies, a routine intervention (awareness training, psychotherapy or medical treatment) was compared with an additional mobile application; in three studies, a routine intervention was compared with a mobile application. As a result of the evaluation, different results were obtained in terms of the effectiveness, acceptability and usability of mobile applications. It was concluded that mobile applications with psychotherapy content, especially applied together with face-to-face interventions, provided more positive results in reducing the risk of suicide. However, the level of effectiveness may vary depending on the content of the application, the characteristics of the sample, and whether it is a treatment support. All that, it has been determined that mobile applications are usable but that there is strictly limited data on their acceptability.
Conclusion: Mobile applications aimed at preventing suicide are potential tools that can be used in preventing suicide. However, there is no definitive result regarding their alone effectiveness. It is important to increase randomized controlled studies with a large sample, long follow-up period, and high level of evidence.

Authors: Mo Guoyin , Liu Fuhao , Wang Hongjiang , Liu Jiahao , Liu Chengyu
Published: November 2024

As one of the most important dynamic excitation sources, the gear time-varying mesh stiffness is the key parameter of gear system dynamic model. So how to calculate the gear mesh stiffness accurately is of great importance. Based on Euler beam theory, this paper proposes a primitive calculation algorithm (PCA) to calculate the time-varying mesh stiffness of spur gears. A simplified gear model is developed based on nonlinear strain-displacement relationships, and a finite element program is used to simulate the gear's meshing stiffness. The rationality of this method was verified through finite element analysis. The results indicate that mesh stiffness plays a crucial role in controlling mesh deformation. In view of this, this study lays a theoretical foundation for further analysis of the vibration and noise of gears.
Time-varying Meshing Stiffness Calculation of Spur Gears with Asymmetric Spalling Defects
Authors: Han Wenqiang , Jiang Hanjun
Published: November 2024

Gear systems are subjected to repeated loads during long-term operation, and factors such as insufficient lubricant to increase friction between gears, resulting in elevated temperatures and wear, are highly susceptible to tooth spalling. Tooth spalling is a common form of failure in gear failure. In previous studies, the vibration response of a gear pair with spalling defects at the tooth center near the pitch circle has been investigated. However, the location of the spalling defects offset from the center of the tooth flank is rarely studied. Tooth spalling faults occur in the pitch circle, but not necessarily in the center of the tooth, often formed on both sides of the center of the tooth and torsion in the meshing process. the symmetric and asymmetric rectangular spalling defects are considered, the torsional deformation is introduced. “torsional stiffness” is introduced into the overall TVMS due to the spalling defect. Therefore, it is meaningful to grasp the reasons for the formation of tooth spalling.

Experimental Study on the Crushing Strength of Diamond Grains
Authors: Yao Jianlin , Liu Bin , Li Yong
Published: November 2024

This study investigates the crushing strength of single diamond grains of varying grades and particle sizes using the WDW-100 electronic universal testing machine. The research aims to understand the mechanical properties of diamond particles, which are critical for optimizing the performance of diamond tools in industrial grinding processes. High-grade diamond particles, characterized by their regular polyhedral shapes and minimal impurities, exhibit higher and more stable maximum load forces compared to medium- and low-grade particles. Medium-grade particles show a balance between strength and brittleness, while low-grade particles display significant variability in their structural integrity due to higher impurity levels and defects. The study also reveals that larger diamond particles tend to have lower average maximum load forces, attributed to increased crystal defects and pronounced grain boundary effects. These findings underscore the importance of considering both the grade and particle size of diamond grains in applications requiring high mechanical strength. The insights gained from this research are essential for improving the design and durability of diamond tools, ensuring their efficiency and longevity in industrial applications.

Authors: Wang Rongjun , Zhang Tilang , WanYan Jianfei , Chen Yang , Xu Junsong , Qiao Zhiyong
Published: November 2024

Roadbed construction occupies a core position in highway construction, but its quality is easily constrained by multiple factors such as changing environmental factors, the performance of construction equipment, and the professional abilities of construction personnel, leading to potential quality risks. Traditional quality inspection methods are mostly carried out after construction is completed, making it difficult to achieve continuous and real-time monitoring of roadbed compaction quality, which to some extent limits the real-time feedback and adjustment of construction quality. Vibration compaction technology has been widely used in the field of highway engineering due to its high efficiency and speed. The compaction degree is directly related to the durability and service life of the highway; therefore, accurate and efficient detection of compaction degree is crucial. This article proposes a method for detecting roadbed compaction degree by integrating machine learning (ML) and vibration acceleration signals. This method aims to achieve accurate evaluation of roadbed compaction by real-time monitoring and analysis of vibration acceleration data, combined with the powerful prediction and classification capabilities of ML algorithms. The experimental results show that this method not only improves the detection efficiency, but also significantly enhances the accuracy of compaction degree detection.
Bifurcation Characteristics Analysis of Gear System Considering Time-varying Gear Backlash
Authors: Liu Jiahao , Liu Chengyu , Mo Guoyin , Liu Fuhao
Published: November 2024

Dynamical models for super gear systems have been established, considering both fixed gear backlash and time-varying gear backlash. The focus is on analyzing the modeling process of the time-varying gear backlash. Based on this, a six degrees of freedom bending-twisting dynamical model for super gears has been developed. Then, using rotational speed as the control variable, numerical simulations have been conducted to compare the bifurcation characteristics of super gear systems with fixed gear backlash and time-varying gear backlash. The results indicate that the overall trends of the bifurcation characteristics for both systems are consistent, with their vibration periods decreasing as the rotational speed increases, leading to a gradual stabilization of the system. However, the bifurcation characteristics of the super gear system considering the time-varying gear backlash exhibit a distinct leading trend, showing significant jump phenomena at relatively low rotational speeds.
Dynamic Analysis of Helical Gears Considering Friction
Authors: Liu Chengyu , Liu Jiahao , Fang Shengjie , Liu Fuhao
Published: November 2024

The use of high contact ratio (HCR) gears is an effective method to reduce single tooth loads, as well as vibration and noise, making the application of helical gears increasingly widespread. Although the presence of helix angles can cause significant relative sliding, the presence of more teeth in contact makes HCR gears more sensitive to surface quality. The existing literature mainly investigates geometric optimization, load distribution, or efficiency calculation of helical gears. The research on the influence of rough surfaces on the dynamic performance of helical gears is very limited. To this end, a multi degree of freedom mathematical model of static transmission error was established based on the 2-DOF system. The relative sliding friction was studied using different friction coefficients, and the influence of different friction coefficients on the gear system was analyzed in detail. The numerical results indicate that surface roughness has a relatively small impact on the dynamic transmission error of the system, but has a significant impact on the motion and friction in the direction of departure.

Published: November 2024

This study presents an experimental investigation of tool wear and chip shape after turning 6060 aluminium alloy using wiper and conventional cutting tools under dry cutting conditions. The influence of parameters such as cutting speed, feed rate, depth of cut, and tool type on tool wear and chip shape were examined. A Taguchi L9 orthogonal array was employed to optimise the cutting parameter, and the effect of each parameter on tool wear was determined using analysis of means (ANOM) and analysis of variance (ANOVA). It was found that a combination of a cutting speed of 1000 rpm, feed rate at 0.1 mm/rev, and depth of cut of 0.5 mm achieved minimal tool wear when dry turning 6060 aluminium alloy using wiper tools. Also, the ANOVA indicated that the main factor contributing to lower tool wear was cutting speed followed by feed rate, with percentage contribution ratios (PCRs) of 54.75% and 37.67% respectively. This confirms that the relationship between cutting speed and tool wear is proportional. Additionally, the ANOVA results demonstrated that the depth of cut, and tool type had little impact on tool wear. Although the wiper and conventional tools are made of similar material with different nose geometries, the wiper insert showed limited abrasion at the higher cutting speed compared to the conventional one. All turning tests produced long irregular continuous curled chips at the beginning of the cutting process, which then changed from the curled to a string-like shape wrapped around the insert tip and the machined part at the end of the turning process. Meanwhile, all the cutting parameters were found to have only a minor impact on chip shape when dry turning 6060 aluminium alloy. Keywords: Dry turning, 6060 aluminium alloy, wiper and conventional coated carbide tools, tool wear, chip shape.

The General Electricity Company of Libya (GECOL) has experienced a surge in electricity demand in recent years, leading to power shortages, particularly during peak summer months. These shortages, often exacerbated by system outages caused by large generating unit failures or transmission line disruptions, have significantly impacted the country's stability. This is further compounded by the ongoing political instability in Libya, which, coupled with electricity supply issues, has negatively affected oil and gas production in some of the country's largest fields. This research addresses the challenge of electricity load demand forecasting by employing Machine Learning (ML) techniques, specifically focusing on Medium Term Load Forecasting (MTLF) based artificial intelligence algorithms. The study compares the accuracy and convergence of different ML methods against actual consumption data, aiming to identify the most effective approach. Accurate load forecasting is crucial for electrical utilities like GECOL to effectively meet customer demands and optimize power generation and transmission. Focusing on Benghazi, this research pioneers the application of Machine learning techniques to predict total energy consumption and demand. The study's findings are validated against real-world data obtained from GECOL's Benghazi Regional Control Center (BRCC), demonstrating the potential of ML for improving electricity load forecasting in Libya. The study concluded with the following results: The Extra Trees Regressor algorithm produced the best results for pregnancy as a target, with an accuracy value of 85%. The Huber Regressor algorithm produced the best results for deficit quantity as a target, with an accuracy value of 77%. Keywords: GECOL, Machine Learning, Load Forecasting, Medium Term Load Forecasting, MTLF.

As the global demand for renewable energy sources continues to rise, wind energy has emerged as one of the most important and sustainable methods for generating electricity. Wind energy stands out for its ability to operate continuously compared to solar power, and it is particularly cost-effective in areas with consistent high winds. With advancements in technology, the cost of electricity generation from wind turbines has become competitive with traditional methods, further highlighting its global significance. To ensure the efficiency and longevity of wind turbines, it is essential to implement robust protection and monitoring systems. In this research, we propose the design and implementation of a control system using Arduino and the LM35 temperature sensor to monitor the temperature of the wind turbine generator. The system will automatically shut down the turbine when the generator's temperature exceeds 70°C, thereby preventing damage and ensuring continuous, efficient energy generation. The proposed system provides precise temperature monitoring and triggers a shutdown when necessary, with the potential to integrate a cooling system for enhanced performance in high-temperature environments. This research contributes to improving automated protection systems for wind turbines, enhancing the effective use of wind energy while reducing the likelihood of mechanical and electrical failures caused by overheating.

The study explores the relationship between corporate social responsibility (CSR), human resource management (HRM), client satisfaction, and business efficiency in Pakistani food and beverage manufacturing SMEs. Despite increasing interest in CSR, its effects on SME performance remain unclear. The research uses partial least squares structural equation modeling (PLS-SEM) to analyze survey data from 75 companies. Results show that CSR has significant positive direct effects on execution, HRM practices, and customer satisfaction. Firm performance strongly influences customer satisfaction, and CSR indirectly affects customer satisfaction. The study provides valuable insights for managers in the food and beverage sector, suggesting that integrating CSR into business strategies can yield tangible benefits. Future research directions include longitudinal studies and broader industry representation.

Published: November 2024

Bu makale, 20. yüzyılın önde gelen şairlerinden Muhammed Hüseyin Şehriyar'ın şiirlerinde dil ve milliyet şuuru kavramlarını inceleyerek onun ana dilini yüceltme çabasını ve kültürel mirasa katkılarını analiz etmeyi amaçlamaktadır. Şehriyar, "Haydar Baba'ya Selam" adlı ünlü şiirinde Azerbaycan Türkçesini kullanarak halk arasında güçlü bir manevi uyanış yaratmış ve ana dilinin gücüyle halkının ruhuna dokunmuştur. Şehriyar, Azerbaycan Türkçesi aracılığıyla millî kimlik ve kültürel değerleri koruma mücadelesi vermiştir. Makalede, Şehriyar’ın klasik edebî mirasa olan bağlılığı ve çağdaş İran ile Azerbaycan şiirinde edindiği konum değerlendirilirken dil uğruna verdiği mücadelenin önemi de vurgulanacaktır. Ayrıca onun eserlerine yönelik eleştiriler, dil ve kimlik bilinci bağlamında ele alınacaktır.
