GREEN ENERGY FOR “SELF RELIANT INDIA”: WILL INDIA ACHIEVE ZERO CO2 EMISSION TARGET BY 2070?
Authors: Dr. Rahat Jehan
Published: April 2024

Energy, power, or electricity is an important infrastructure factor affecting the country’s economic growth and welfare. The demand for energy in India has increased by more than 60% per capita since 2000. India is also responsible for a 10% rise in the world’s energy demand since 2000. The increasing demand has made the world move forward with reliable renewable energy sources instead of non-renewable energy ones. There are mainly three triggers why the world including India is focusing on green and clean energy sources- first- because of climate change mitigations, second- energy security, and 3rd- net-zero targets.  Due to the current status of the climate crisis, a sustainable economy has now become a challenge. Understanding the need for renewable energy the Govt. has announced INR 20.97 trillion revival package for the economy. While addressing the COP 26 summit the Govt. of India also has committed to ambitious targets of expanding the capacity to 175 GW of renewable energy by 2022, and 500 GW of non-fossil fuel energy by 2030 at the Net Zero target by 2070. India has ranked 4th in wind power, and 5th in solar power and renewable power installed capacity in 2021. But still, only 23% of the electricity is produced by renewable sources in India. It is therefore a matter of concern that such a landmark policy will succeed as our economy is still reliant on fossil fuel energy sources. This paper also discusses the achievements and challenges to achieving the clean and green energy targets for Aatm Nirbhar Bharat.

This paper tries to place Sreenarayana Guru in the context of Kerala modernity. Narayana Guru was one of the well-known social reformers in India. He was a philosopher, a poet, a mystic, and a social revolutionary. He desired to spread the message of the mystic experience and the presence of divine to one and all in society. When the divine has embraced him all kinds of ignorance and inequalities have been destroyed. Then his motive was to destroy inequalities injustice; on the earth. So, his motive was dual, one is to spread the divine message and the second is to destroy inequalities, injustice. When Narayana Guru came on the scene in the mid-19th century Kerala Society was under the clutches of an ugly caste system with all the evil effects, divisions, and sub-divisions based on caste hierarchy. Guru’s philosophy generated great influence on marginalized people. His path and commandments discharged energy, which shifted the roots of the existing social order, marginalized stand against the dominant ideology, and ruled out its prohibitions. They demanded a better lifestyle and education. In the realm of the Kerala social reforms, his thoughts generated change which positively shaped masses towards freedom.

Published: April 2024

In the realm of cloud server operations, where the sheer volume of daily transactions is immense, safeguarding data security is paramount. One of the significant challenges faced is the verification of transaction logs, as attackers may attempt to tamper with them. The current system, utilizing Proof of Work (PoW) for blockchain, falls short by lacking robust data encryption, thereby exposing a critical vulnerability. This proposed paper introduces an innovative solution by integrating the more secure and energy-efficient Proof of Stake (PoS) algorithm with Blowfish encryption. The combination of PoS and Blowfish addresses the identified weaknesses effectively. PoS introduces a novel approach by relying on validators who have a stake in the network, creating a powerful deterrent against log tampering. This not only enhances the integrity of the transaction logs but also reduces the risk of malicious activities. Additionally, the incorporation of Blowfish encryption ensures the confidentiality of log data, providing an extra layer of protection. Even if logs are accessed illicitly, the encryption prevents unauthorized individuals from deciphering sensitive information. Furthermore, the implementation of a smart contract for user registration adds another dimension to security, creating a comprehensive solution to fortify data security on Cloud servers. The proposed approach offers a promising solution to the critical cybersecurity challenge faced by cloud servers. By combining the security features of PoS and Blowfish encryption, along with the strategic use of smart contracts, the solution not only deters tampering but also safeguards sensitive information. This holistic approach contributes significantly to reinforcing the data security infrastructure of cloud servers in the face of evolving cyber threats.

Characterization studies must be prioritized to allow the maintenance of the racial standard to guarantee the conservation of their genes of origin. The Nordestina breed is a small animal, not exceeding 150 cm for males and 145 cm for females, with a body weight of approximately 280 kg in both sexes. The objective of this research was to compare the conventional method and the imaging method (ImageJ® software) in the performance of morphometric measurements of horses of the Nordestina breed. The morphometric measurements performed were withers height (WH), croup height (CH), body length (BL), neck length (NL), side height (SH), pelvic girdle height (PGH), shin perimeter (SP), chest circumference (CC), face length (FL) and face width (FW). Head length (P=0.045), head width (P=0.001), and shin perimeter (P<.0001) showed a significant difference between the two methods evaluated, these measurements presented higher values when performed by image, but did not present a coefficient of variation greater than 8%. The total canonical correlation between the sets of variables X and Y were 0.99, and the first pair of canonical variables absorbed 85% of the total variation, whose Wilk's and F test (P<0.001) were significant for all canonical pairs, which indicates a strong correlation between the measurements obtained by the conventional method and by imaging. The evaluation of photographs by the ImageJ® software proved to be a viable alternative to the conventional method of taking morphometric measurements in horses of the Nordestina breed.

Authors: Aslanov T. G. , Ibragimov S. A.
Published: April 2024

Objective. The goal of the study is to optimize a computer model of a Vivaldi antenna with conductive plates on the same side as the resonator.

Method. The study is based on electrodynamic modeling methods.

Result.The paper presents a computer model of a Vivaldi antenna with conductive plates on one side with a resonator. A comparative analysis of two types of Vivaldi antennas was carried out of the dependence of the beam width and the voltage standing wave ratio on the radius of the current-conducting plate curve in the form of lobes and the values of the opening in two planes θ = 900 (the plane of the antenna's opening) and φ = 00 (the plane perpendicular to the antenna's opening plane) in the frequency range from 3 to 24 GHz. The influence of the shape, size and position of the resonator on the SWR value and the width of the antenna radiation pattern was determined. VSWR values are given for different shapes and sizes of the resonator. The main parameters of the resonator have been identified, which affect the characteristics of the antenna.

Conclusion. Electrodynamic modeling allows us to obtain a Vivaldi antenna with the required radiation pattern width with an improved standing wave ratio.
Methods for assessing the connectivity of an undirected bipolar labeled graph taking into account the destructive impact of external threats on its vertices
Authors: Voevodin V. A. , Krahotin N. A.
Published: April 2024

Objective. The main arguments that position the problem of assessing the connectivity of the bipolar graph in relation to the conditions of destructive impact of external threats (threats) as relevant for assessing the vitality of information systems (IS) are discussed operating under conditions of information security threats.

Method. The following are presented: formulation of the problem of assessing connectivity for conditions of exposure to threats; a brief overview of existing methods for structural modeling of bipolar structures; results of the analysis of the applicability of existing methods for assessing the stability of functioning (stability) of bipolar structures in relation to conditions of exposure to threats. The initial conditions are accepted: the stability of the information system as a whole depends deterministically on the stability of its structural elements and the network structure itself; the problem of assessing the connectivity of a two-pole structure is basic for assessing the connectivity of the corresponding multi-pole structures; the stability analysis of the impacted object is carried out using minimax criteria, and the result is presented in the form of the minimum value of the stability function and the moment in time of the occurrence of this event.

Result. Limiting factors that prevent the use of existing methods to solve the problem have been identified. The main limiting factor is that existing methods are based on probabilistic stationary models that require representative statistics. The second, no less important limiting factor is that the situation characterizing the impact of threats is very dynamic (not stationary), the events themselves are very rare, and the assessment period is comparable to the period of response to threats, which does not allow obtaining effective assessments of sustainability. It is proposed to: generalize existing methods for conditions of non-stationary functioning process, for which, when assessing, take into account changes in the probabilistic characteristics of nodal elements over time; as an indicator characterizing connectivity, use the minimum value of the stability function determined during the period of exposure to threats. The price to pay for ensuring the sustainability of the functioning of the affected object under the influence of threats is the need to ensure structural redundancy.

Conclusion. The results of the study can be used by persons who simulate both the object of impact and the processes of its functioning, to make a decision on ensuring the continuity of production processes under the conditions of the impact of threats.

Published: April 2024

Objective. The purpose of the work is to apply mathematical modeling methods to solve problems of ensuring road safety on highways.

Method. Quantitative methods for analyzing road safety problems (BDD) are based on probability theory, mathematical statistics, information theory, multifactor analysis, reliability theory, modeling, programming and other mathematical methods.

Result. The main trends in the study of road safety problems are considered. It is indicated that the mathematical dependences of the influence of a limited number of factors are unsuitable for a satisfactory description of the “driver-vehicle-road-environment” (VADS) system as a whole. Paying attention to the uncertainty of objects, properties and connections of the VADS system, the need to use a systematic approach in solving these problems is justified. The need to take into account regional conditions in road safety is discussed. Mathematical models recommended for solving problems of ensuring road safety are presented.

Conclusion. Generalization, systematization of the vast empirical material of road accidents accumulated as a result of specific studies taking into account economic, social and demographic conditions and the development of theoretical concepts based on system representations are the most important conditions for solving the problems of ensuring road safety.

Authors: Egunov V. A. , Surin V. S. , Stupnitskiy P. S. , Akhmetova R. D.
Published: April 2024

Objective.The research presented in the paper is aimed at studying the effectiveness of modern DBMSs.

Method.Along with traditional relational solutions, NoSQL-based DBMSs are becoming increasingly popular. This is primarily due to the ability of such systems to store and process huge volumes of data. At the same time, to work effectively with this data, it is necessary to ensure its compression. Compression allows you to reduce the amount of stored data and provide quick access to it.

Result.A comparative analysis of data compression in the MySQL and OpenSe DBMS was performed.

Conclusion.Data compression in OpenSearch is more efficient than in MySQL when using standard algorithms. OpenSearch is an excellent choice if youneed to conserve storage resources while making optimal use of the processor, otherwise both systems will do the job well.

Published: April 2024

The need to assess the vulnerability of non-engineered residential RCC buildings in Nepal has become urgent, especially considering the ongoing modifications and additions to these structures without understanding their susceptibility to seismic events. Many residential buildings, particularly those up to three stories, did not fully comply to the guidelines outlined in Nepal Building Code NBC 105:2020. Therefore, there is a necessity to assess the seismic performance of these structures. This study aims to quantify the seismic vulnerability of such buildings by focusing on three distinct types: regular two and three-story structures, and irregular three-story structures. Using finite element modeling, the analysis of the buildings’ seismic capacity was performed through pushover analysis. Subsequently, linear time history analysis is conducted to determine the seismic demand. Two software were utilized to conduct the analyses, namely SAP2000 and STERA_3D. The study also includes the matching eleven strong ground motion inputs to Nepal’s site characteristics and response spectrum to ensure the relevance of the local context. Furthermore, fragility curves are constructed to compare the probability of structural failure, by first conducting the nonlinear dynamic analyses on the building specimens. The result showed that the probability of complete failure rises rapidly when an additional story is constructed with vertical irregularity, increasing from 1.8% to 5.7% in a non-engineered two-story building. The study also observes variations in top displacement across all three buildings due to differences in earthquake duration and frequency. From the findings, it is revealed that a significant increase in seismic vulnerability for vertically irregular buildings compared to regular ones

Published: April 2024

Abstract: In the backdrop of India's agrarian-centric economy, the precision of crop yield prediction and the adoption of optimal farming practices emerge as critical components for sustainable agricultural development. This research paper introduces an innovative methodology that integrates data mining techniques, machine learning algorithms such as Support Vector Machines (SVM), and Regression algorithms, along with a comprehensive attribute analysis to establish a resilient crop yield prediction and recommendation system. The proposed system draws insights from a diverse range of attributes crucial for agriculture, including geographical location, soil pH for alkalinity assessment, nutrient percentages (Nitrogen, Phosphorous, and Potassium), real-time weather conditions sourced from third-party APIs, soil type, nutrient composition, and regional rainfall data. By amalgamating and scrutinizing these multifaceted attributes, our system aspires to furnish farmers with precise and dependable predictions regarding their crop yields.
