 Abstract

This study is devoted to the finite element analysis of Spherical Dome with openings under static loading which result from the weight of dome and a concentrated load at the crown to obtain the most economical size of opening that can be provided at different locations and to obtain the optimum location (in terms of angle with horizontal) at which an opening of a particular size can be provided. Equations have been developed for most economical aspect ratio and optimum angle at which openings should be provided for various cases of Spherical Dome with 2 openings, 4 openings and 6 openings. Variations in maximum stress intensity produced in the dome due to increase in aspect ratio and increase in angle of opening have been shown. Change in maximum stress zone due to increase in aspect ratio have also been shown

 Abstract

India's retail sector (industry) is expanding faster than anybody could have predicted. Around the past few years, the Indian retail industry has drawn attention from all around the world. India's middle class segment expansion, favourable demographics, changing lifestyles, rising disposable incomes, and significant potential for market penetration in both urban and rural areas all contributed to the country's retail boom. It is anticipated that since 2011, the proportion of organized retail would rise from 5% to 10%. Aditya retailer, Bharti limited, Reliance retail store, Pantaloon showroom, Visal mart, Tata retail, Raheja limited, and Piramals retail sectors are just a few of the prominent corporate companies that have diversified in order to increase the size of their retail portfolios. The goals and difficulties that organized retail players in India encounter are the main topics of this study. According to research, organized retailers' main obstacles include the competitiveness of the unorganized sector, internal logistical problems, retail shrinkage, and competition among organized retailers.

 Abstract

In Mayureswar II block of Birbhum district, West Bengal, a research project was conducted on farmers' perceived prevalence of climate change, as evidenced by phenomena like rising temperatures, fluctuating rainfall, etc., and in the areas considered agro-ecological areas. The aim of the study was to determine the extent of the farmer's opinion about the climate change and their adaptation strategies to deal with losses caused by the climate change. The farmers' perspective of climate change had a significant impact on their readiness to adjust their cultivation and production practices in response to the changing environment, as evidenced by the findings. The results demonstrated that respondents with a high level of perception on climate change were farmers. Based to the results, half of the respondents expressed optimism about their ability to deal with the effects of climate change if they received the necessary government support. Merely about 13% of farmers thought positively of the government's climate change policies. About the adaptation tactics, the majority of respondents did not adopt any strategies in this regard, whereas 40% of respondents adopted techniques to some extent.

 Abstract

The rapid adoption of multi-level inverters in electric drives and renewable energy systems underscores their pivotal role in modern power electronics. These inverters offer significant advantages over traditional two-level inverters, including reduced dv/dt stress, lower total harmonic distortion (THD), and diminished common mode current. However, prevalent multi-level inverter topologies, such as neutral point clamped, cascaded H-bridge, and flying capacitor inverters, present challenges that impede optimal performance. This paper introduces a novel three-phase two-level inverter topology aimed at addressing common mode voltage and current issues inherent in existing designs. The proposed topology integrates two cascaded converters and leverages device junction capacitance (DJC) to implement a neutral point clamping methodology, thereby enhancing the inverter's operational stability and efficiency. A comprehensive analysis using the switching function concept reveals the impact of DJC on the inverter's performance. The study further explores a sophisticated PWM control scheme designed to optimize the modulation process and minimize common mode voltage variations. Simulation results, conducted using MATLAB, demonstrate the superiority of the proposed topology over conventional and H7 two-level inverters. Key performance metrics such as pole voltage, phase voltage, common mode voltage, and total harmonic distortion (THD) are evaluated, showcasing significant improvements. The proposed inverter achieves a THD reduction to 61.41%, compared to 91.81% and 88.01% for conventional and H7 inverters, respectively. This research not only advances the field of power electronics but also provides practical insights for engineers and researchers. By addressing critical issues in multi-level inverter design, the proposed topology paves the way for more efficient and reliable power conversion systems, contributing to enhanced energy efficiency and sustainability in contemporary applications.

 Abstract

In essence, the voluntary carbon market relies on independent certification bodies and their standards to ensure the credibility of carbon credits, leading to fragmentation due to the presence of multiple entities. This fragmentation, coupled with varying perceptions of credit quality, influences the demand and pricing dynamics within the market. These two types of markets function differently and have distinct objectives. The key difference lies in what is being bought and sold. Both markets deal with a tonne of CO2, but in an Emissions Trading System (ETS), companies trade pollution permits (often referred to as "allowances") that permit them to emit one tonne of CO2. When a company emits 1tCO2, it must surrender one permit to the regulator. In contrast, an offsetting mechanism involves the trade of offsets, or emission reduction units, which represent a tonne of CO2 that has already been reduced. Offsets can only lead to a zero-sum game, because one tonne of CO2 is emitted somewhere, and one tonne is reduced somewhere else. Hence, they cannot be used to reduce emissions in the long term and are not compatible with the idea of going towards net-zero emissions at a global level. Offsets should only be used to compensate for emissions that cannot be avoided or reduced . The paper looks into all these aspects.

 Abstract

India has emerged as one of the fastest-growing major economies globally, driven by strategic reforms and robust policy initiatives. This research article explores the pivotal roles of trade, infrastructure, and finance in propelling India's economic growth. Trade liberalization and diversification have significantly boosted export performance, integrating India more deeply into the global economy. Concurrently, ambitious infrastructure projects like the Bharatmala Pariyojana and the Smart Cities Mission are transforming transportation and urban living standards, enhancing connectivity and productivity. Financial sector reforms, including banking stability measures, financial inclusion initiatives, and the promotion of digital payments, have fortified the economic framework, ensuring resilience and broad-based growth. The synergy between these sectors has created a conducive environment for sustained economic development. However, challenges such as infrastructure deficits, regulatory complexities, and skill gaps remain and need to be addressed to maintain growth momentum. This article provides a comprehensive analysis of how these three critical areas collectively contribute to India's rapid economic ascent and discusses future prospects and strategies for continued progress.
