    Get PDF
    There is a lot of interest in a compound with improved mechanical power, toughness, wear resilience, and increased electric and thermal conductance. This work examined the tribological conduct and fabrication of the titanium metal matrix composite (TiMMC) augmented with graphene (Gr) and tungsten carbide (WC) fragments. The TiMMC, which had 8 percent mass percentages of WC and Gr, was created using stir casting. Taguchi's L27 orthogonal grid method was used for designing the tribological investigations, which were then conducted as wear experiments with a pinon-disc gadget. ANOVA and Taguchi's study show that loading and range have the most effect on wear percentage, accompanied by speed.By examining the worn areas of the composite samples using scanning electron microscopy, the wear mechanism was determined. The wear rate statistics were correctly categorized by machine learning classifying techniques such as random forest, support vector machines, and XG-Boost methods, which provided accuracy values of 72%, 66%, and 56.3%, respectively. Notwithstanding the encouraging outcomes, the research acknowledges that the system's efficiency may differ depending on certain properties of the composite component and operating circumstances. Therefore, it motivates further research to validate and extend these novel discoveries over a larger range of components and circumstances. &nbsp

    In this research, Advanced Finite Element Methods (FEM) for engineering applications’ fluid dynamics problem solving are investigated, where high order discretization, hybrid solvers and AI enhanced FEM models are studied. SUPG, VMS and DG methods were analyzed in terms of their accuracy and efficiency of computation. We calculated about 35% reduction in numerical diffusion using SUPG vis a vis conventional FEM carried out at Reynolds numbers Re = 10⁵ to 10⁷. Turbulence modeling accuracy was enhanced by 28% with VMS approach, whereas 42% increased shock capturing capability have been realized with DG-FEM. Moreover, the computational time was reduced to 50% by integrating physics informed neural networks (PINNs) at a 97% accuracy level. The research also validated hybrid mesh free FEM approaches that allow 15% higher efficiency in fluid structure interaction problems. The fact that we can implement these findings in the context of real time engineering applications using AI enhanced FEM techniques indicates that these are strong candidates. Finally, the study shows that the advanced FEM methods are more accurate, more stable and far more computationally efficient than traditional models. FEM solvers accelerated by GPU and adaptive meshing strategies should be explored in future research for further optimality

    Development of a Modified Predictive Coding Algorithm for High-Resolution Image Compression in Real-Time Structural Health Monitoring of Metallic Component

    Get PDF
    Real-time monitoring requirements of structural integrity in metallic components across aerospace and automotive and civil engineering sectors drive the need to create reliable image compression methods. The detection of small defects including cracks and corrosion as well as deformations depends greatly on high-resolution imaging systems. The massive amount of generated image data creates problems with both data storage and its transmission requirements. The research advocates for developing a Modified Predictive Coding (MPC) algorithm which specializes in real-time high-resolution image compression for Structural Health Monitoring (SHM) systems. The proposed Modified Predictive Coding algorithm builds on predictive coding yet adds adaptive context modeling tools alongside edge-preserving processes to balance visual quality with high compression ratio fulfillment. This method surpasses traditional approaches by making prediction parameter modifications which happen automatically according to image local features in order to protect essential diagnostic information. Testing of the algorithm took place using a high-resolution image dataset containing metallic surface images which faced different stress scenarios. The proposed method underwent performance evaluations that applied Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM) and Compression Ratio (CR) metrics for assessment. The experimental findings show that MPC algorithm achieves higher compression efficiency and maintains visual quality better than JPEG2000 and SPIHT methods do. Its fast processing abilities along with low latency system make MPC strongly compatible with deploying SHM systems utilizing edge devices and IoT methodologies. The research analyzes how the algorithm would function with sensor networks and cloud-based analytics systems for improving predictive maintenance decision capabilities. The Modified Predictive Coding algorithm proves to be a suitable technology for efficient high-quality image compression which enables prompt accurate assessment of metallic structures in critical infrastructure. This research initiative creates an opportunity to study advanced compression methods which unite machine learning with predictive coding for smart SHM system applications

    An Interrogation of Dream and Disillusionment in F. Scott Fitzgerald’s The Great Gatsby

    Get PDF
    This essay aims to demonstrate that F. Scott Fitzgerald is interested in dream and the disillusionment that follows from it in his The Great Gatsby. The wealthy gangster, Jay Gatsby, the protagonist, longs for a beautiful, upper-class woman but eventually loses his heart. The tragedy of all dreamers is also exemplified by the story of the gangster, a youngster from the Midwest who is chasing the American dream of success. The rise and fall of a handsome bootlegger who became obsessed with the wealthy and attractive Daisy Buchanan was recounted in this novel. Whether the paradise lost is a Midwestern boyhood, Paris in the 1920s, or Gatsby’s platonic ideal of Daisy, it is the quintessential American story of social aspiration and the frequently terrible results of innocence betrayed. The novel explores American themes and presents a portrayal of the new social reality that the moralist tradition in America fears. The world that the story explores is one of strained relationships, one that prioritises wealth and success over societal duty, and one where people have much too much control over their own lives. In this novel, Fitzgerald has combined the American dream with the American disillusionment

    Unifying Temporal Reasoning and Agentic Machine Learning: A Framework for Proactive Fault Detection in Dynamic, Data-Intensive Environments

    Get PDF
    Modern enterprises depend heavily on complex IT infrastructures which must be continually monitored for signs of internal failures. These systems generate vast amounts of time series data, but this data is rarely utilized for proactive detection of emerging anomalies and faults. Instead, alert systems are poorly tuned to high-volume, low-fidelity rules. We argue that time series data gives rise to unique challenges in fault detection, including temporal dependencies, agents working asymmetrically, synchronicity, and varying time granularity. However, traditional techniques in alarm tuning and anomaly detection do not succeed in modeling these properties. This is why we call for the unification of two established research fields—temporal logic and temporal pattern mining in temporal reasoning, and multiagent reinforcement learning in agentic ML. Many assertions and expectations must be placed on the agents and their learning interactions, and which of them evolve. We outline requirements for a temporal agentic fault detection framework and our thesis that without an explanatory, accountable temporal model of entity interactions, proactive alerts will produce mostly false positives and have poor effects on complex nonstationary environments. We call for research collaboration to produce a toolkit drawing together the best of the temporal reasoning and agentic ML worlds. This toolkit for researchers and practitioners in complex systems will allow them to consider events and patterns from both horizons and then explore them with multicriteria time-based search and temporal multiarmed bandit functions. Output from these diverse functions can inform the final semantic entity relationship specification, as well as a variety of agentic objective functions that support the full temporal scale from immediate to multiweek backup. &nbsp
