 Abstract

this paper proposes a new three-phase modular multi-level inverter (MMLI). The proposed inverter consists of repeated modular primary cells that are connected in series configuration. Therefore, the proposed topology can be extended to get more output voltage levels by adding additional cells without increasing voltage stresses across power switches. Both sinusoidal pulse width modulation (SPWM) and staircase mod- ulation are successfully applied to the proposed inverter. The proposed inverter features many advantages such as reduced number of semiconductor power switches, driver circuits, dc- voltage sources, simplified control algorithm, and reduced volt- age stresses across the switches independent of output voltage level. Furthermore, the performance of the proposed inverter is studied under both open-loop and closed- loop operations for highly inductive load. Beside the obtained simulation results, a laboratory prototype has been carried out and tested to verify the control techniques and performances of the topology. Simulation and experimental results are compared together to highlight the similarity and consistence of them.

Abstract This study examines the historical evolution, cultural significance, and contemporary challenges of Satras--monastic institutions central to the Neo-Vaishnavite movement initiated by Srimanta Sankardeva in the 15th-16th century Assam. Rooted in the philosophy of Ekasarana Nama Dharma, Satras have served as centers of devotional worship, artistic expression, education, and social reform. Functioning under the guidance of the Satradhikar and sustained by the disciplined life of resident monks (bhakats), these institutions preserve sacred texts such as the Kirtan Ghoxa and Nam Ghoxa, laterally with presentation civilizations with Sattriya dance, Borgeet music, Ankia Naat plays, and Bhaona drama. Beyond religious practice, Satras have historically fostered egalitarianism, confronted caste hierarchies, promoted the Assamese language, and acted as centers of native education and ethical training. In the contemporary era, Satras face pressures from modernization, globalization, declining patronage, youth migration, and the commercialization of cultural practices. Although national and international credit of art forms like Sattriya has augmented visibility, it also risks thinning their devotional spirit. To address these tests, the study climaxes preservation strategies, including government and NGO initiatives, community engagement, addition of heritage into academic curricula, formation of digital archives, and raise of heritage tourism with protections.

 Abstract

This study presents a comprehensive trend analysis of the revenue receipts and expenditures of the Government of Assam for the period 2008 to 2022. The objective is to examine the fiscal sustainability of the state by exploring growth trends, identifying fiscal imbalances, and establishing statistical relationships between receipts and expenditures. Using descriptive statistics, correlation, paired t-test, and regression analysis, the study evaluates the fiscal health of Assam. The analysis reveals a general upward trend in both revenue receipt and expenditure, with instances of fiscal surplus and deficit across the years. The findings suggest a strong positive correlation between revenue receipt and expenditure. However, fluctuations in the fiscal gap point towards challenges in revenue adequacy and expenditure control. Policy implications highlight the need for better fiscal planning and revenue mobilization.

 Abstract

This study explores the linguistic development of Assam, a region marked by rich ethnic diversity and cultural plurality. It traces the historical evolution of the Assamese language alongside the tribal and minority languages that coexist in the state. The research examines the influence of socio-cultural movements, colonial policies, and political changes on language growth and preservation. Additionally, it highlights the contemporary challenges faced by minority languages in the face of modernization and globalization. The study underscores the importance of inclusive language policies, community involvement, and technological interventions for sustaining Assam's linguistic heritage. This comprehensive analysis aims to contribute to a deeper understanding of Assam's linguistic identity and promote efforts for its preservation and development.

 Abstract

Mathematical Logic and Set Theory form the foundational pillars of modern mathematics, providing the necessary tools for rigorous reasoning, formal proof structures, and the development of advanced mathematical theories. This paper explores the historical evolution, fundamental concepts, and critical roles of these disciplines in shaping mathematics and its applications. We discuss their contributions to computer science, philosophy, linguistics, and theoretical physics, while also addressing contemporary challenges and extensions. Through a systematic review, this study highlights the indispensable nature of logic and set theory in both pure and applied mathematics. This paper delves into the profound and often understated significance of mathematical logic theory and set theory as the bedrock of modern mathematics. We explore their historical origins, fundamental concepts, and their pervasive influence across diverse mathematical disciplines and interdisciplinary applications. Beginning with the formalization of reasoning and the concept of collections, we demonstrate how these theories provide the necessary rigor, consistency, and universality for mathematical inquiry. From establishing the foundations of number systems and analysis to shaping the development of computer science and artificial intelligence, logic and set theory are shown to be not merely abstract constructs but essential tools for understanding and advancing scientific knowledge.

 Abstract

These days, algorithms and data structures are crucial to computer science since they enable us to store, process, and analyze vast amounts of data. Several techniques are used in data structures to arrange the data. We think that seeing the minaction is the greatest method to comprehend algorithms and data structures. For a range of algorithms, we created interactive visualizations that are simple enough for the human brain to comprehend and use. The goal of this project's development is to make algorithms simply understandable to humans. Additionally, this effort improved our understanding of algorithms and data structures. Traditionally, theoretical and mathematical analysis has been used to examine data structures and algorithms. As a result, it is time-consuming, difficult to study, and lacks understanding of how an issue is applied in real life. We have created and supplied an idea, data structures, and algorithm to help teachers and students visualize data structures and algorithms with their real-world implementation.

 Abstract

National Education Policy (NEP) 2020 has finally opened the door for the world of 21st-century education. The policy builds from the foundational principles of access, equity, quality, affordability, accountability and an inclusive education system. One of the most remarkable aspects of NEP 2020 is that it acknowledges how teachers are supposed to play various roles in the classroom. Educators are now seen as mentors and facilitators. The policy stresses teacher training focused on the needs of the socio-economically disadvantaged groups. Technology is highlighted as a vehicle to integrate into teacher education and classroom practice to improve learning outcomes. Teachers are the backbone of the education system. The implementation of NEP 2020 is an ambitious agenda, so it has many challenges. Some key recommendations are outlined below.
