This article presents the fault analysis and differential protection scheme of the three phase Power Transformers (PT). The relay operates mainly during the internal fault condition and it must be insensitive to any fault outside the zone of protection. In this paper, a fuzzy logic based differential protection schemes has been used. It blocks the tripping through outer fault and internal fault conditions. The simulation result of FLC with disparity relay for 3 phase transformer shows fast tripping during internal fault and also avoids the mal operation of relay during external fault.

This paper focus on designing of Electric Tonga gives emphasis on two domains namely electrical and mechanical. It scrutinizes all available technologies to find solutions to all issues to above mentioned domains. The major focus was to recreate the conventional Tonga by replacing the animal mode of transportation to electro-mechanical mode of transportation which can be run using Renewable energy. This recreated Tonga is eco-friendly, less cost, and creates less pollution. The three major components are a rechargeable battery, motor and wheels. Battery supplies electrical power to the motors which converts this electrical power into mechanical power and gives them to the wheels via a shaft. The Tonga could carry two to three passengers at a time from one point to the other. It is possible to incorporate a solar panel which can provide a secondary source of energy input other than battery, as well as an Arduino with line follower to control the Tonga. The paper aims to promote tourism and to use Tonga available without torturing animals.

Education plays a powerful role in building a nation. Education decides the future of the nation and the destiny of its people. The impact will be a long-lasting one in terms of the growth and development of the nation and its citizens. The role of education and its importance cannot be overlooked in today's world. International styles and conditions are already influencing India's higher education. For the last number of years, India has attracted a good number of foreign students, including NRIs, in larger numbers, who join various skilled, tutorial, and academic programs. Also, many foreign universities are offering students the opportunity to get their degrees without leaving India. There are trends to liberalise university systems in a way that enables them to reduce the gap with private universities. Although India has made significant steps in terms of improving access to and participation at all levels of education, the common picture of the country's growth in education is complicated, and there are many ongoing problems and difficulties associated with exposure and participation in education that the country's growth rate in education. education delivered, educational equity, system efficiency, governance, and governance. The issue of higher education in India has always been prominent as one of the major drivers of public space travel. A good education, of course, opens the way to a rewarding career.  The nature of programmes offered by HEIs has undergone a massive transformation, resulting in the acquisition of mastery-level skills and competencies that are in greater demand. Degrees generating employment opportunities would be the most likely to be chosen in the future. All of us are deeply concerned about the quality and accessibility of higher education. Advances in digital technology are changing the way educational resources are developed, communicated, and accessed around the world. The use of digital technologies in all sectors of higher education has also gained significant attention in India. This, in turn, helps to improve the quality and accessibility of higher education for a large number of students, as well as the upskilling of teachers across the country. In this prevalent scenario, NEP 2020 is introduced to give thrust to the Indian education system and propel it to the next level. The New Education Policy 2020 announced by the Government of India became a welcome change and news amidst all the bad things happening around the world. Over time, various committees have recommended that the education budget increase be increased to 6% of GDP. This has led to the interest of researchers. The announcement of NEP 2020 was unexpected by many. The proposed NEP 2020 reforms have been something that many academic experts have never seen coming. Although education policy has had an equal impact on school and college education, this article focuses on NEP 2020 and its impact on higher education. This paper also outlines key featur
教育在国家建设中起着强大的作用。教育决定国家的前途和人民的命运。就国家及其公民的增长和发展而言,其影响将是持久的。教育的作用及其重要性在当今世界不容忽视。国际风格和条件已经影响了印度的高等教育。在过去的几年里,印度吸引了大量的外国学生,包括nri,他们参加了各种技能,辅导和学术课程。此外,许多外国大学为学生提供不离开印度就能获得学位的机会。现在有一种趋势是开放大学系统,使它们能够缩小与私立大学的差距。尽管印度在提高各级教育的可及性和参与度方面取得了重大进展,但该国教育增长的总体情况是复杂的,在教育曝光和参与方面存在许多持续存在的问题和困难,影响了该国教育的增长速度。教育交付、教育公平、制度效率、治理、治理。印度的高等教育问题一直是公共空间旅行的主要推动力之一。当然,良好的教育为有回报的职业铺平了道路。高等教育院校所提供课程的性质已发生巨大转变,使学生掌握更大的技能和能力。创造就业机会的学位将是未来最有可能被选择的。我们所有人都深切关注高等教育的质量和可及性。数字技术的进步正在改变世界各地教育资源开发、交流和获取的方式。在印度,在高等教育的所有部门使用数字技术也引起了极大的关注。这反过来又有助于提高大量学生接受高等教育的质量和可及性,并提高全国教师的技能。在这种普遍情况下,新经济政策2020被引入,以推动印度教育体系,并将其推向下一个水平。印度政府宣布的2020年新教育政策在世界各地发生的坏事中成为一个受欢迎的变化和新闻。随着时间的推移,各种委员会都建议将教育预算增加到GDP的6%。这引起了研究人员的兴趣。新经济政策2020的宣布出乎许多人的意料。新经济政策2020改革的提议是许多学术专家从未预料到的。虽然教育政策对学校和大学教育产生了同等的影响,但本文的重点是新经济政策2020及其对高等教育的影响。本文还概述了新经济政策的主要特征,并分析了它们对现有教育体系的影响。

Wireless technologies have grown at a speed and with the passing year, it shows clearly that their consumers are also increasing, that increment in wireless spectrum consumer increases the demand for spectrum. But for our wireless systems, the spectrum is divided into two categories: the first is licensed and the second is unlicensed. Licensed spectrum is used by authorized users and unlicensed spectrum is free for all users. But most of the time it is shown the hat licensed spectrum may not be properly utilized by primary users (PUs), at that time spectrum band is free. To mitigate that inappropriate use of spectrum cognitive radio (CR) network is used. In CR there is one challenge that among the CR node some nodes experience an impact of multipath and shadowing, and another is to sense the spectrum under a lower signal to noise ratio. To overcome the effect of multipath and shadowing co-operative spectrum sensing has been used but it has large energy utilization. This extra energy is consumed in sensing the spectrum and reporting each nodes local decision to Fusion Centre (FC). In this paper we discuss three different schemes for total sensing time and energy decrement or throughput improvement. Here we go after for the genetic algorithm and integer linear programming scheme for overall energy minimization and throughput maximization.
无线技术的发展速度很快,随着时间的推移,它清楚地表明,他们的消费者也在增加,无线频谱消费者的增加增加了对频谱的需求。但对于我们的无线系统,频谱分为两类:第一类是授权的,第二类是未经授权的。授权频谱仅供授权用户使用,未授权频谱对所有用户免费。但大多数情况下,主要用户(pu)可能没有很好地利用许可频谱,此时频谱是空闲的。为了减轻频谱认知无线电(CR)网络的不当使用。在CR中,一个挑战是在CR节点之间的一些节点受到多径和阴影的影响,另一个挑战是在较低的信噪比下感知频谱。为了克服多径和阴影的影响,采用了协同频谱感知,但其能耗较大。这些额外的能量被用于感知频谱并向融合中心(FC)报告每个节点的本地决策。本文讨论了三种不同的总传感时间和能量减少或吞吐量提高方案。在这里,我们将讨论总体能量最小化和吞吐量最大化的遗传算法和整数线性规划方案。

But for our wireless systems, the spectrum is divided into two categories: the first is licensed and the second is unlicensed. Licensed spectrum is used by authorized users and unlicensed spectrum is free for all users. But most of the time it is shown the hat licensed spectrum may not be properly utilized by primary users (PUs), at that time spectrum band is free. To mitigate that inappropriate use of spectrum cognitive radio (CR) network is used. In CR there is one challenge that among the CR node some nodes experience an impact of multipath and shadowing, and another is to sense the spectrum under a lower signal to noise ratio. To overcome the effect of multipath and shadowing co-operative spectrum sensing has been used but it has large energy utilization. This extra energy is consumed in sensing the spectrum and reporting each nodes local decision to Fusion Centre (FC).

Genetic advancements have shown that ALS is not a single entity but consists of a collection of syndromes in which the motor neurons degenerate. Together with these multiple genetic etiologies, there is a broad variability in the disease’s clinical manifestations in terms of the age of symptom onset, site of onset, rate and pattern of progression, and cognitive involvement. In this paper, prediction of human paralysis is done based on extraction of features from the ALS dataset samples. The classification has been carried by two different Machine Learning based algorithms i.e., Gradient Boosting (GB), and neural Network (NN). The standard data set such as ALS has been used for this purpose. The classifier model has used 80% data as a training set and the remaining 20% of data as the test set. The result shows that GB and NN perform better with an accuracy of 98%. Based on the desired accuracy, this classification model serves better compared with existing models.
遗传方面的进展表明,ALS不是一个单一的实体,而是由运动神经元退化的一系列综合征组成。与这些多种遗传病因一起,该疾病的临床表现在症状发作的年龄、发病部位、进展的速度和模式以及认知受累方面存在广泛的差异。在本文中,基于ALS数据集样本的特征提取来预测人类瘫痪。分类由两种不同的基于机器学习的算法进行,即梯度增强(GB)和神经网络(NN)。标准数据集(如ALS)已用于此目的。分类器模型使用80%的数据作为训练集,剩余20%的数据作为测试集。结果表明,GB和NN的准确率达到98%。基于期望的准确率,该分类模型与现有模型相比具有更好的服务。
