 Abstract

The wireless communication sector requires inexpensive, small antennas that can resonant for multiband operations with a respectable gain. Metal components in the traditional antenna configuration provide energy loss and conduction loss at higher frequencies. The Dielectric Resonator Antenna (DRA) is a good option for these issues. It is made of dielectric resonator material, which is devoid of metal components. The DRA provides a sufficient and steady response for metrics like return loss, gain, bandwidth, and VSWR at high frequencies because there is no conductive material present. The need for single antennas that can operate across several frequency bands in wireless applications is addressed in this paper using a unique approach. Multiband operation is made possible by the modified U-slot design of a single circular patch antenna. The antenna's usefulness is increased by incorporating these slots, which support WLAN, Extended WiMAX, and International Mobile Communication Systems. However, low gain is a common problem with microstrip patch antennas. In order to address this, the multiband antenna is positioned above a Cylindrical Dielectric Resonator Antenna (CDRA). The CDRA is 1.6 cm in radius and 9 cm in height, and it is made of polypropylene, which has a dielectric constant of 2.2. Through simulations using the EM Flow solver HFSS, the Modified U-Slot Multiband Circular Patch Antenna with Cylindrical Dielectric Resonator Antenna meets the required return loss criteria across its working frequencies and exhibits enhanced gain performance. The ultimate goal of the Honey Badger Algorithm (HBA) is to improve the efficiency, dependability, and range of this proposed cylindrical dielectric resonator antenna. This algorithm is based on the behavior of honey badgers, which use their sense of smell and honey guide birds to navigate toward the honeycomb.

 Abstract

This paper explores integrating solar energy in Unmanned Aerial Vehicles (UAVs) to extend flight endurance and reduce reliance on conventional power sources. It examines the use of solar panels, lightweight batteries, and energy management systems for optimal performance. Challenges such as weight, energy efficiency, and environmental factors are discussed. The integration of solar power is used, which offers a sustainable solution for long-duration UAV operations. Due to solar and battery hybrid systems, it enhance its efficiency and flight time.

 Abstract

The rapid growth of social media has transformed how businesses engage with consumers, particularly in the e-commerce sector. This study investigates the impact of social media engagement on brand loyalty, analyzing how various digital interactions contribute to consumer trust and long-term relationships with brands. With platforms like Instagram, Facebook, and Twitter becoming essential for business marketing, brands increasingly rely on real-time engagement, influencer collaborations, and user-generated content to foster loyalty. Utilizing a mixed-methods research approach, this study incorporates surveys and case studies from leading e-commerce platforms to examine consumer behaviors and brand interactions. The findings suggest that businesses with strong social media engagement experience higher customer retention and repeat purchases. Personalized advertising, direct customer interactions, and influencer marketing are identified as key factors driving brand loyalty. Additionally, user-generated content enhances authenticity and encourages wider consumer participation, strengthening brand credibility. The study concludes that e-commerce brands must strategically optimize their social media presence by focusing on interactive and personalized engagement. Understanding the nuances of digital consumer behavior can help businesses refine their social media strategies to build stronger customer relationships and drive sustained loyalty in an increasingly competitive market.

 Abstract

Virtual Try-On (VTO) technology is becoming popular in India, allowing people to see how clothes, glasses, or makeup look on them using AI and AR. While this makes shopping easier, it also raises concerns about how personal data is collected and used. This study explores how comfortable Indian consumers are with sharing their data for VTO, focusing on their awareness, opinions, and privacy concerns. A survey of people aged 18-35 helps understand if they prefer convenience over data security. The results will help businesses build trust and find a balance between personalization and privacy. By looking at consumers' attitudes, the study aims to guide companies on how to handle data responsibly. Understanding these concerns will also help businesses improve VTO features while ensuring privacy is respected. This balance can lead to better user experiences and more successful adoption of VTO technology in India.

 Abstract

This study explores the level of awareness and understanding of Systematic Investment Plans (SIPs) among investors in Coimbatore and examines the impact of SIP investments on financial planning. The study also analyzes the relationship between investors' awareness and the growth of SIPs while identifying the challenges faced by potential investors in understanding the benefits and risks associated with SIPs. Statistical tools such as the test Chi-square are used to determine the association between demographic factors and SIP awareness. One-way ANOVA is applied to analyze differences in satisfaction levels across various demographic groups, and Factor Analysis helps identify key factors influencing SIP adoption. The findings offer valuable insights for financial institutions and policymakers to develop targeted awareness programs and enhance financial literacy, thereby promoting disciplined investment practices in Coimbatore.

 Abstract

The Vehicle Data Prediction is an innovative web-based application designed to classify vehicle movement data as either legitimate or falsified using Machine Learning. With the increasing need for reliable traffic monitoring, logistics optimization, and fraud detection, this system provides a user-friendly interface where users can input key vehicle parameters such as position, speed, and acceleration. The entered data is then processed through two powerful machine learning models Logistic Regression and Random Forest Classifier which yields accuracy of 77.63% and 89.08% which analyze and predict the authenticity of the data.

 Abstract

Public debt can be strategically used as a counter-cyclical measure to stabilise the economy during economic downturns. Increased government spending through borrowing can stimulate economic activity. In India, public debt includes the Union government's total liabilities that must be paid from the Consolidated Fund of India (Article 292). SDG 17, focusing on "Partnerships for the Goals," recognizes the importance of global cooperation and financial resources for achieving sustainable development, including addressing public debt sustainability, a key aspect for India. India's stance on SDG 17 includes promoting a fair and equitable trading system and assisting developing countries in achieving long-term debt sustainability. Public Debt in India, today, is raised to meet the government's revenue deficits (the difference between the income of the government and money spent to run the government) or to finance public works (capital formation). As of March 2024, the Central government's outstanding debt stood at INR175 lakh crore, more than double the INR96 lakh crore recorded in March 2020. India's debt-to-GDP ratio stands at approximately 83.1% as of 31.03.2024. It marks a significant increase from pre-pandemic levels, where the ratio hovered around 69% until 2018. The World Bank is an international development organization owned by 187 countries. Its role is to reduce poverty by lending money to the governments of its poorer members to improve their economies and to improve the standard of living of their people. This study investigated the impact of public debt from 2019 to 2026 in India.

 Abstract

This study investigates the performance, efficiency, and environmental impact of alternative gases in domestic Electrolux refrigeration systems. Traditionally, ammonia is used as the primary refrigerant, with hydrogen as an auxiliary gas. However, alternative gases such as carbon dioxide, propane, butane, and water vapor are explored for their thermodynamic properties and feasibility. The study evaluates cooling capacity, coefficient of performance (COP), energy consumption, and environmental sustainability. Experimental results highlight potential improvements in efficiency and reduced environmental impact. The findings provide insights into optimizing absorption refrigeration technology for enhanced sustainability and cost-effectiveness in domestic applications.
