This study goes beyond previous efforts by incorporating fractional temporal evolution instead of linear temporal evolution in the concatenation model. This would facilitate the regulation of the internet bottleneck phenomenon by enabling the deceleration of internet traffic in one direction at a node while maintaining its full flow in the other direction. The model presents a novel approach that contributes to a deeper understanding of potential applications in the telecommunication industry. The implemented technique presents several solitons. In addition to those solitons, the method presents solutions in terms of Jacobi and Weierstrass elliptic functions. A full spectrum of optical solitons are thus recovered. This will include bright solitons, dark solitons, singular solitons, and straddled solitons. The existence criteria of such solitons, in the form of parameters constraints, that naturally emerged during the course of derivation, are presented. The recovered solitons will be presented in the paper that can be efficiently implemented to mitigate the internet bottleneck effect.

Various technologies, such as Total Stations (TST), Light Detection and Ranging (LiDAR), and Global Positioning Systems, are conventionally used to obtain stockpile volumes; however, DOTs seek a faster, safer way to obtain an object’s volume with minimal workforce training. Uncrewed Aircraft Systems (UAS), coupled with visual imagery, have the potential to address these limitations; however, UAS visual has not been effectively developed to account for flight parameters in measurements, such as Ground Sampling Distance (GSD). Images of regular and irregular objects were collected in several flights to measure their geometries. The measurements were performed using a computer vision algorithm and a common commercially available photogrammetry tool (Pix4D) as UAS visual and UAS LiDAR. The results indicated that UAS visual is a viable technology that provides consistently accurate measurements of stockpiles of various sizes. The authors used Pix4D to measure volumes ranging from 0.45 m³ to 2838 m³ with errors ranging from 4 % to 6 %. The results indicated that ensuring a GSD value of 0.80 cm in visual imagery can lead to accurate volumetric measurements of irregular objects. To reduce the processing time, a deep leaning-based point cloud classification model was developed to detect the objects of interest, stockpiles, and separate them from irrelevant objects. The average volume difference between the volume predicted using Pix4D and point cloud classification was less than 5.5 %. Finally, we compared the advantages and challenges of UAS with traditional methods and UAS LiDAR in terms of data collection time, cost, limitations, and safety. The results demonstrate that using UAS for stockpile volume measurement is safer and more time-consuming and cost-effective.</div></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":"16 2","pages":"Article 103251"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143177012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IoT consumer devices, from smart home appliances to wearable gadgets, have become ubiquitous daily, facilitating automation and seamless connectivity. However, ensuring their reliability and security presents a tremendous challenge. Anomaly detection methods offer a promising solution, especially those powered by TinyML (Machine Learning (ML) on Tiny Devices). These IoT devices can autonomously identify unusual behaviours or patterns that diverge from regular operation by leveraging the proficiencies of deep learning (DL) techniques enhanced for resource-constraint environments, like neural networks. Incorporating DL, anomaly detection, and TinyML allows real-time monitoring and proactive mitigation of malfunctions or security breaches in IoT devices. This advanced technology ensures improved reliability, privacy, and overall user experience in the dynamic landscape of connected devices, whether identifying irregular health data or detecting unauthorized access attempts on a smart door lock from the wearable fitness tracker. Therefore, this study develops a new Deep Learning technique to secure IoT consumer devices with TinyML Driven Real-time Anomaly Detection for Predictive Maintenance (DLTML-RTADPM). The DLTML-RTADPM technique aims to recognize and categorize the anomalies in IoT consumer devices. At the primary phase, the DLTML-RTADPM model normalizes the input data using Z-score normalization. In the DLTML-RTADPM method, the Fennec Fox Optimization Algorithm (FFA) is used for a high dimensionality reduction process where the optimal feature set is chosen. The DLTML-RTADPM technique implements gradient least mean squares with a bidirectional long short-term memory (GLMS-BiLSTM) approach for anomaly detection. To further improve the detection results of the DLTML-RTADPM technique, the Jaya optimization algorithm (JOA)-based hyperparameter tuning process is utilized. A series of simulations are performed on the benchmark dataset to ensure better detection outcomes of the DLTML-RTADPM model. The investigational validation of the DLTML-RTADPM method portrayed a superior accuracy value of 98.11% over other techniques.</div></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":"16 2","pages":"Article 103281"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143178378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, optimizing the deposition process to generate high-quality CdTe devices remains a challenge since deposition factors such as pressure have a substantial impact on the structural, optical, and electrical properties of the films, eventually influencing device performance. This study explores the effects of deposition pressure during the Close-Spaced Sublimation (CSS) process on the structural, morphological, optical and electrical characteristics of CdTe thin films, with an emphasis on pressures ranging from 1 to 10 Torr. High-quality CdTe films with large grain sizes (∼3 µm), cubic (111) preferential crystallite orientation, low dislocation density, and decreased strain are grown at deposition pressures ranging from 1.5 to 2 Torr, according to structural studies. These properties are appropriate for producing high-performance p-type CdTe absorber layers for solar cells. The optimized films has a band gap of 1.49 eV, a Voc of 0.64 V, a Jsc of over 18 mA/cm², and solar cell efficiencies above 5 % under normal AM1.5 conditions. Films deposited at higher pressures (≥5 Torr) exhibit poor electrical performance, including poorer carrier mobility, higher recombination losses, and low Jsc due to carrier dispersion and grain boundary defects. This work emphasizes the importance of deposition pressure in managing the balance of crystallinity, grain size, and carrier concentration, all of which are required for optimal solar cell performance. The findings present a systematic approach for optimizing CSS deposition parameters in order to achieve higher-efficiency CdTe thin-film solar cells. Furthermore, this study provides the groundwork for future research focusing on pressure-dependent manufacturing processes and post-deposition treatments to increase the efficiency, stability, and scalability of CdTe-based solar cells.</div></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":"16 2","pages":"Article 103255"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143177841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its design may impact gender equality by either facilitating or hindering equal access to public amenities for both men and women. The entrenched constraints on equal opportunities for women in establishing social activities, particularly in ideologically traditional developing countries like Iran, create observable disparities in the usage of public amenities. This research aimed to develop a comprehensive framework fostering equal opportunities for both men and women in static social activities around street furniture. To achieve this, the research employed a mixed-methods approach. The study combined empirical field observations, space syntax analysis, and interviews with users of public spaces. The space syntax analysis was used to evaluate spatial integration and connectivity, while interviews provided qualitative insights into how men and women interact with urban furniture. Observational data helped identify patterns in the use of street furniture by different genders. The results indicated that street furniture positively influences the social logic of space by enhancing spatial integration and connectivity, thus improving overall accessibility to public spaces for social activities. However, a significant gender imbalance was observed, with men predominantly using street furniture more frequently than women. This disparity highlights conflicting perspectives on gender equality in public space usage. The findings suggest that achieving a more equitable gender distribution in public spaces requires designing street furniture that reduces visual integration and connection while increasing the visual clustering coefficient and entropy, thereby creating more inclusive environments.</div></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":"16 2","pages":"Article 103250"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143178048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
