 Abstract

Ceramic Matrix Composites (CMCs) represent a significant advancement in materials engineering, offering a unique combination of high-temperature resistance, superior mechanical strength, and enhanced durability compared to conventional monolithic ceramics. By incorporating reinforcing fibers or particles within a ceramic matrix, CMCs effectively mitigate the intrinsic brittleness of ceramics, thereby improving their toughness and structural integrity under extreme conditions. These materials exhibit exceptional thermal stability, excellent resistance to oxidation and corrosion, and superior mechanical performance, making them highly suitable for demanding applications in aerospace, automotive, energy, and biomedical industries. This paper provides a comprehensive review of CMCs, covering their fundamental types, including oxide-oxide, carbon-carbon, and silicon carbide-based composites, along with a detailed analysis of their microstructural characteristics and composition. Various processing techniques such as chemical vapor infiltration (CVI), polymer infiltration and pyrolysis (PIP), and hot pressing are discussed, highlighting their impact on material properties and performance. Furthermore, an in-depth exploration of the mechanical behavior of CMCs, including strength, toughness, creep resistance, and fatigue performance, is presented, with comparative assessments against traditional ceramic and metallic materials. The paper also examines the diverse industrial applications of CMCs, particularly in aerospace turbine components, automotive brake systems, thermal protection systems, and nuclear energy applications, where their lightweight nature and ability to withstand harsh environments provide a competitive advantage. Additionally, current challenges such as cost-effective manufacturing, processing complexities, and long-term durability concerns are addressed. Emerging trends and future research directions, including the integration of nanomaterials and advancements in fabrication techniques, are also explored to highlight the potential for further innovation in the field. To enhance understanding, figures, bar charts, and tables are included throughout the paper, illustrating key properties, processing methodologies, and performance comparisons with conventional materials. Through this analysis, the study aims to contribute to the ongoing development and optimization of CMCs for next-generation engineering applications.

 Abstract

A Monte Carlo algorithm for extracting contours in 2D images is proposed in this paper. A multiple model Particle Filter (PF) for progressive contour growing (tracking) from a starting point is designed, accounting for the convex, noncircular form of delineated areas. The algorithm relies on image intensity gradients as measurements and requires information about four manually selected points: the seed point, the starting point, arbitrarily selected on the contour, and two additional points, bounding the measurement formation area around the contour. The filter performance is studied by segmenting contours from series of simulated ultrasound medical images and Ground Penetrating Radar (GPR) images

 Abstract

Urban supply management is essential to sustain water supply. Bhandara, a small city in Maharashtra, is undergoing immense difficulties and challenges in water supply for uninterrupted and efficient utilization by the residents of this medium-sized urbanization. In this context, this paper discusses the enhancement of water supply management in Bhandara City (2016-17) using modern information systems. Further, it enlightens readers concerning the implementation and usability of diversified information technologies during the course, including Geographic Information Systems (GIS), Supervisory Control And Data Acquisition (SCADA), and the smart water systems. This paper analyzes how Information Systems can support the water supply system of Bhandara by evaluating existing infrastructure, challenges, and potential improvements toward efficiency and losses. The paper adopts a mixed method approach to achieve results that are supported by both primary data as well as existing data and literature.

 Abstract

The expansion of online communication is happening at a dizzying pace. The internet has made it possible to establish an international "Virtual Community" that is unconstrained by space and time. Anyone may now easily connect with experts all across the globe thanks to the internet. You may ask for advice from experts by video chat, voicemail, or email. With no longer any assurance of privacy whether using wired or wireless ways, the Internet has evolved into a hostile environment. The challenge with transmitting multimedia material online is keeping it secure and private. The increasing need for fast data transmission and storage has put multimedia apps in a precarious position, since they use a lot of bandwidth. Encryption and compression of data are essential for data security, safeguarding data resources during transmission and storage, especially on networks. Encrypting images before compression is necessary for high-level security. Arnold Transform, Combinatorial Random Permutations, and Cyclic Permutation of Prediction Errors are the three techniques that we provide for grayscale photo encryption. By repeatedly applying linear transformations and mod functions to different pixel places, Arnold Transform is able to encrypt data. When iterations are performed several times, the relationship between adjacent pixels is completely broken. To make data encryption as foolproof as possible, the Combinational Random Permutation method mixes bits, pixels, and blocks. By encrypting the prediction error domain rather than the actual image, the Cyclic Permutation of Clusters of Prediction Errors technique achieves excellent security.

 Abstract

The intersection of women's rights and human rights reveals a persistent dichotomy that underscores the challenges women face in attaining true equality and dignity globally. Despite notable advancements in women's participation in the workforce and public life, the transition from numerical representation to genuine empowerment remains sluggish. This paper examines the systemic and cultural barriers that hinder women's progress into leadership roles across various sectors, particularly in politics and business. Key issues such as gender-based discrimination, unequal pay, and work-life balance challenges contribute to a slow trajectory toward gender parity. Additionally, the scarcity of mentors and role models perpetuates a cycle of underrepresentation, limiting opportunities for aspiring women leaders. This analysis highlights the need for targeted interventions to dismantle these barriers and promote a more equitable landscape for women, ensuring that human rights are not just an abstract ideal but a lived reality for all women.

 Abstract

The Medium encompasses a range of communication methods like print media, broadcast media, and digital platforms, which play a vital role in reaching and informing society. It includes print materials like books and magazines as well as channels like television and radio. Media serves as a tool for storing and delivering information, spanning print, electronic, and social media, among others. It keeps individuals updated on various aspects of life. In the modern world, media takes forms such as newspapers, TV, movies, social media, and more. Media education is crucial in promoting health awareness, reaching different audiences through channels like mass media and tailored messages for communities and professionals. Mass media is pivotal in educating about health and influencing behaviours. While media remains an essential source of health information, excessive social media use can contribute to mental health issues. Media's importance was highlighted during the COVID-19 pandemic, disseminating accurate information and countering misinformation. Health education methods utilize media tools and teaching aids. Health promotion occurs at various levels, and media awareness training is crucial for understanding information dissemination methods. Media significantly influences culture, society, and public opinion, offering a platform for awareness, entertainment, and information exchange. It helps individuals stay informed about global events, but its effects are not without risks. Overall, a comprehensive understanding of media's methods, uses, and impacts is essential in today's world.
