K. J. Kumar, R. Sudhir Kumar, V. Nandakumar
The aim of this paper to check the voltage and frequency response of three phase solar PV grid tie string inverter during low voltage ride through. The LVRT performance of an inverter is being checked by its compliance to Central Electricity Authority (CEA), India guidelines, 2019 for grid tie equipment. The study shows that the voltage of the inverter follows the grid with LVRT but in case of frequency, small transients were observed. Similarly, the voltage harmonics generated by the inverter is within the limit throughout the curve but exceeds 5% during the transition from 100% to 15% voltage level.
本文的目的是对三相太阳能光伏并网串逆变器在低压穿越过程中的电压和频率响应进行校核。逆变器的LVRT性能正在通过其是否符合印度中央电力局(CEA) 2019年并网设备指南进行检查。研究表明,在LVRT下,逆变器电压随电网变化,但在频率变化情况下,逆变器电压瞬变较小。同样,逆变器产生的电压谐波在整个曲线范围内,但在从100%电压电平到15%电压电平的过渡过程中超过5%。

Data Mining Algorithms and Statistical Techniques for Identification of Schizophrenia: A Survey 识别精神分裂症的数据挖掘算法和统计技术:一项调查
Jobin Thomas, T. Thivakaran
Schizophrenia is a severe psychiatric condition marked by multiple symptoms, including perceptions, delusions and cognitive problems. Often, schizophrenia may difficult to identify because there is no diagnostic examination yet to identify it. Throughout recent years, machine learning methods have been widely extended to the study of neuroimaging evidence to better identify such disorders. The objective of this paper is to provide a systematic investigation of data mining techniques in Mental Health literature and provide research inputs for schizophrenia. We have investigated on all possible techniques applied in the research of Schizophrenia and concerns to be considered in future works. This review explains challenging research opportunities. Researches based on symptoms/external factors and data sets used are also given importance in this article.
精神分裂症是一种严重的精神疾病,其特征是多种症状,包括知觉、妄想和认知问题。通常,精神分裂症可能难以识别,因为还没有诊断检查来识别它。近年来,机器学习方法已被广泛扩展到神经影像学证据的研究,以更好地识别此类疾病。本文的目的是对精神卫生文献中的数据挖掘技术进行系统的调查,并为精神分裂症提供研究投入。我们已经调查了在精神分裂症研究中应用的所有可能的技术以及在未来工作中要考虑的问题。这篇综述解释了具有挑战性的研究机会。基于症状/外部因素和使用的数据集的研究在本文中也给予了重视。

Convolutional Neural Network based Handwritten Devanagari Character Recognition 基于卷积神经网络的手写体德文汉字识别
P. Gupta, Saurabh H. Deshmukh, S. Pandey, Kedar Tonge, Vrushabh Urkunde, Sainath Kide
Industry 4.0 might be thumping at our door, but there are millions of individuals who are still disconnected from even the most fundamental technologies. One of the major reasons for this disparity is the language gap. The majority of them don't know English, which is the de-facto language for most of the technologies. Only 12.6% of all Indians speak English according to the 2011 census. Language is the medium through which an individual expresses himself or herself. Education of the rural section of society is one of the most important things to accomplish if we aim to develop the country. Because of this, there is a need for a reliable software solution for recognizing the traditional scripts. This would also be helpful for the purpose of remote schooling in times of lockdown and quarantine.The paper proposes a methodology for recognition of handwritten ‘Devanagari’ characters. Devanagari being one of the most common scripts, is used in many Indian dialects. The Hindi language is also written in the Devanagari script as shown in Fig 1. This paper explores and analyzes the use of Deep learning techniques such as the Convolutional Neural Networks for the recognition of Devanagari characters. Inspired by the structure of the brain, CNNs classify characters by making use of neurons linked in various layers so as to achieve maximum efficiency. In this paper, 6 layers of neurons were used for the purpose of classifying Devanagari characters. An accuracy of 95.6% was achieved in this approach. Once recognized, the handwritten Devanagari characters can easily be translated into English or any other languages.
工业4.0可能正在敲响我们的大门,但仍有数百万人无法接触到最基本的技术。造成这种差异的主要原因之一是语言差异。他们中的大多数人不懂英语,而英语是大多数技术的实际语言。根据2011年的人口普查,只有12.6%的印度人会说英语。语言是个人表达自己的媒介。农村社会教育是国家发展的重要内容之一。因此,需要一种可靠的软件解决方案来识别传统脚本。这也有助于在封锁和隔离期间进行远程教育。本文提出了一种手写体“梵文”汉字识别方法。Devanagari是最常见的文字之一,在许多印度方言中使用。印地语也用德文加里文书写,如图1所示。本文探讨并分析了卷积神经网络等深度学习技术在Devanagari字符识别中的应用。受大脑结构的启发,cnn利用各层连接的神经元对字符进行分类,以达到最大效率。本文采用6层神经元对Devanagari字符进行分类。该方法的准确率达到95.6%。一旦识别,手写的梵文字符可以很容易地翻译成英语或任何其他语言。

Chatbot is an Artificial Intelligence program that stimulates interactive human conversations with computers. It plays a vital role now-a days due to its 24/7 support for customer queries. Web app chatbot uses a Linguistic machine learning algorithm (NLP) for predicting correct responses for human queries. LUIS (Language Understanding Intelligent Service) is a natural Language processing Artificial Intelligence for predicting human queries. In this paper, chatbot is implemented on LUIS for predicting the user queries. Based on the highest prediction score, Luis detects the intents and entities, to solve user queries. A web app chatbot discussed in this paper is fast, accurate and secure with high performance. Using LUIS API’s for automated LUIS training and publishing the endpoint to the chatbot. Enhanced authentication secures the bot from unauthorized persons accessing the chatbot.

Load-flow studies are carried out with ETAP (14.0) software which simulates current operating conditions for the steady-state system that allows an assessment of bus voltage profiles, actual and reactive power flow and losses. The load-flow analysis conducted using various scenarios ensures that the power system is correctly designed to meet the performance requirements. The benefits of the electricity flow study decrease unforeseen downtimes, minimal operational and maintenance costs and obtain more capacity from existing assets. The main purpose of this study is to develop a new load-flow technology for all network nodes without that the network.

Leaf Disease Detection and Classification based on Machine Learning 基于机器学习的叶片病害检测与分类
Sandeep Kumar, K. Prasad, A. Srilekha, T. Suman, B. Rao, J. V. Vamshi Krishna
Detection of diseases in plants is a significant task that has to be done in agriculture. This is something on which the economy profoundly depends. Infection discovery in plants is a significant job in the agribusiness field, as having diseases in plants is very common. To recognize the diseases in leaves, a continuous observation of the plants is required. This observation or continuous monitoring of the plants takes a lot of human effort and it is time-consuming too. To make it simply some sort of programmed strategy is required to observe the plants. Program based identification of diseases in plants makes easier to detect the damaged leaves and reduces human efforts and time-saving. The proposed algorithm distinguishing sickness in plants and classify them more accurately as compared to existing techniques.
植物病害检测是农业中必须完成的一项重要任务。这是经济深深依赖的东西。植物感染的发现是农业综合领域的一项重要工作,因为植物病害是非常普遍的。为了识别叶片的疾病,需要对植物进行持续的观察。这种对植物的观察或持续监测需要大量的人力,而且也很耗时。简单地说,需要某种程序化的策略来观察植物。基于程序的植物病害识别更容易发现受损叶片,减少了人力劳动,节省了时间。与现有技术相比,所提出的算法可以区分植物中的疾病,并更准确地对它们进行分类。

This is something on which the economy profoundly depends. Infection discovery in plants is a significant job in the agribusiness field, as having diseases in plants is very common. To recognize the diseases in leaves, a continuous observation of the plants is required. This observation or continuous monitoring of the plants takes a lot of human effort and it is time-consuming too. To make it simply some sort of programmed strategy is required to observe the plants. Program based identification of diseases in plants makes easier to detect the damaged leaves and reduces human efforts and time-saving.
