Debasish Bhattacharjee Victor, Jamil Kawsher, Md Shad Labib, Subhenur Latif
Depression is a prevalent illness in todays society. It changes and influences our entire method of thought and our emotional, cognitive, and everyday behavioral behaviors. It affected over 264 million people, and the proportion increases every day. Mainly when it lasts for a prolonged time, it becomes a severe issue or health topic. It leads the trustworthy person to also malfunction, and that person commits suicide in his final position. There are several causes for depression, though social networking like Facebook, Twitter, and other networking plays a critical role in getting us more depressed. Most people in Asia use Facebook, Twitter, and various chat applications, and there they express their emotions. That is why our research initiative picks social media. Some work has been done on depression but depression detection on the Bengali community is done very rarely. So it has become a strong demand for today. The social media has intialted a study based on depression, tweets, and numerous chat app responses, and gathered Bengali data and projected depression posts and commentaries. Diverse approaches of machine learning have been used to evaluate these data and forecast depression and for algorithm purpose Support vector machine, Random Forest, Decision Tree, K-Nearest Neighbors, Naive Bayes (Multinomial Naive Bayes), Logistic Regression has been used. The desired results can be obtained by adding those algorithms. Moreover, different algorithms send us different results as trends were common, but ultimately the precision was the same for all algorithms applied to our dataset.
抑郁症是当今社会的一种普遍疾病。它改变并影响着我们的整个思维方式以及我们的情感、认知和日常行为。它影响了超过2.64亿人,而且这一比例每天都在增加。主要是当它持续很长一段时间,它成为一个严重的问题或健康话题。它导致值得信赖的人也失灵,那个人在他最后的位置上自杀。导致抑郁的原因有很多,尽管像Facebook、Twitter和其他社交网络在让我们更抑郁方面起着关键作用。大多数亚洲人使用Facebook、Twitter和各种聊天应用程序,他们在那里表达自己的情绪。这就是为什么我们的研究计划选择了社交媒体。已经有一些关于抑郁症的研究,但对孟加拉社区的抑郁症检测却很少。所以它已经成为今天的强烈需求。这家社交媒体已经启动了一项基于抑郁症、推文和大量聊天应用回复的研究,并收集了孟加拉数据,预测了抑郁症的帖子和评论。机器学习的各种方法已被用于评估这些数据和预测抑郁,并用于算法目的支持向量机,随机森林,决策树,k近邻,朴素贝叶斯(多项朴素贝叶斯),逻辑回归已被使用。将这些算法加在一起可以得到期望的结果。此外,不同的算法给我们不同的结果,因为趋势是共同的,但最终精度是相同的所有算法应用到我们的数据集。

Pixel based method for Text to Image Encryption 基于像素的文本到图像加密方法
K. Malathi, R. Kavitha, M. Liza
Normally, the encryption and decryption is done only to convert the text into an encrypted form (i.e.) the confused form of text. In this type of method a hacker may easily hack the text using the public key or private key. So in this paper a new technique called Text to image encryption has been proposed. This will convert the plain text or information into an image format. That image will hide the encrypted text. If the user wants to view the text, first the image is divided into blocks. Each color component will be modified using the secret key. It will be difficult to the hackers to hack the information. This method can be used for large set of databases.
通常,加密和解密只是为了将文本转换为加密形式(即混淆形式的文本)。在这种类型的方法中,黑客可以很容易地使用公钥或私钥破解文本。为此,本文提出了一种新的文本到图像加密技术。这将把纯文本或信息转换成图像格式。该图像将隐藏加密文本。如果用户想要查看文本,首先将图像分成块。每个颜色组件将使用密钥进行修改。黑客很难破解这些信息。该方法可用于大型数据库集。

M. Rahman, Md Saif Kabir, Md Nazaf Rabbi, Mohammad Hashib Sarker, Ishmam Ahmed Chowdhury, Golam Sarowar
DC-DC and AC-DC converters are often used to obtain the craved voltage level. However, the conventional converters are not suitable for high output voltages without depreciating various parameters like conversion efficiency. In this paper, a new Cascaded Buck-Boost Zeta (BBZ) converter topology is proposed. Also, a closed-loop is implemented to improve THD and power factor. This converter’s DC-DC topology can deliver the output voltage as high as 773V along with high conversion efficiency at an 80% duty cycle. The AC-DC topology gives a maximum efficiency of 98.29%. The efficiency levels of both the topology are also relatively high at different duty cycles.
通常使用DC-DC和AC-DC变换器来获得渴求电压电平。然而,传统的变换器在不降低转换效率等各项参数的情况下,不适合高输出电压。本文提出了一种新的级联Buck-Boost Zeta (BBZ)转换器拓扑结构。同时,采用闭环控制,提高了THD和功率因数。该变换器的DC-DC拓扑结构可以提供高达773V的输出电压以及在80%占空比下的高转换效率。AC-DC拓扑的最大效率为98.29%。在不同的占空比下,这两种拓扑的效率水平也相对较高。

Comparative Study of Apache Pig & Apache Cassandra in Hadoop Distributed Environment Apache Pig与Apache Cassandra在Hadoop分布式环境下的比较研究
Y. Gupta, Tanusha Mittal
Big data analytics is the one which acquire, organise and analyse the huge volume of data with high velocity to find some patterns and useful information. The data sets are so large that it can’t be handled by traditional databases to manage and process the structure and unstructured data. Hence, big data tools i.e. Hadoop, is required due to its high scalability, availability and cluster environment mechanism for analysing large volume of data. MapReduce is one of the important components of Hadoop which is able to handle the unstructured data. But to use MapReduce, high programming skills are needed. Therefore, due to the reason of programming, users are moving towards some other tools i.e. Apache Pig or Apache Cassandra. In these tools, the data is simply analysed by executing the queries or commands. This paper will discuss about the architectural of Apache Pig and Apache Cassandra and afterwards both the technologies regarding some factors are compared to find out which one is better.
大数据分析是对海量数据进行快速获取、整理和分析,从中发现一些规律和有用信息的一门学科。数据集非常庞大,传统数据库无法对结构化和非结构化数据进行管理和处理。因此,需要大数据工具,如Hadoop,因为它具有高可扩展性,可用性和集群环境机制,可以分析大量数据。MapReduce是Hadoop中处理非结构化数据的重要组件之一。但是要使用MapReduce,需要很高的编程技能。因此,由于编程的原因,用户正在转向其他一些工具,如Apache Pig或Apache Cassandra。在这些工具中,只需通过执行查询或命令来分析数据。本文将讨论Apache Pig和Apache Cassandra的体系结构,然后将两种技术在一些因素上进行比较,找出哪一种技术更好。

Dynamic Information Retrieval With Chatbots: A Review of Artificial Intelligence Methodology 基于聊天机器人的动态信息检索:人工智能方法综述
V. Dutt, Satya Murthy Sasubilli, Anand Eswararao Yerrapati
A chatbot is a computer program designed to simulate a conversation with human users, especially over the Internet. Ultimately, the chatbot acts like a virtual assistant or interactive agent in a conversations interface to respond to user queries or messages via communication channel like mobile apps, messenger apps or browser-based applications. Chatbots have become more popular nowadays and most of the companies are implementing them wherever they can to reduce the operation cost. In many cases, human resources are utilized to respond to user queries, where the chatbot can do the same job by searching the data in the system so that the human talent can be used for other advanced tasks. As the advancement in the technology, chatbots are also evaluated in a better way such that they can do some other tasks beyond just answering the textual questions. This paper provides a chatbot based solution for users or candidates, who are searching for a job to apply in a company. This solution makes the job searching and applying process easy, where the user can apply for a job in a few taps without visiting the company website or their mobile app.

Nowadays, XML database growth plays a vital role in many real time applications. XML database contains a collection of XML dataset. More analytical functions are applied to XML database by using Xquery. In real world, huge businesses are exchanging the data as XML data model. In general, space and time parameters are considered for Xquery processing in the database. In existing, the analytical operation is analyzed in eXist-DB and BaseX databases with the execution time of ORBDA dataset. In existing system, the prediction analysis operation is not supposed in the dataset. In this paper, Xquery is processed by using Riak database. Riak database produces better execution time than eXist-DB and BaseX. This research has analyzed the prediction operation for ORBDA dataset using machine learning approach. This paper uses various regression techniques to analyze the prediction operation. Machine learning approaches produce better accuracy in prediction. The query processing time is reduced than the existing approach. This research uses ORBDA dataset in demonstration.

The role of Electrical Energy Storage (EES) is becoming increasingly important in the proportion of distributed generators continue to increase in the power system. With the deepening of China’s electricity market reform, for promoting investors to construct more EES, it is necessary to study the profit model of it. Therefore, this article analyzes three common profit models that are identified when EES participates in peak-valley arbitrage, peak-shaving, and demand response. On this basis, take an actual energy storage power station as an example to analyze its profitability by current regulations. Results show that the benefit of EES is quite considerable.

Machine Learning based Digital Beamforming for Line-of-Sight optimization in Satcom on the Move Technology 基于机器学习的移动卫星通信视距优化数字波束形成技术
Arushi Singh, M. Jayakumar
With the evolving communication systems, the need for beamforming to improve the gain of the transmitting or receiving antenna has also increased. Beamforming allows to direct the radiated energy with the intended choice of direction efficiently. The main focus of this work is to develop an effective method for beamforming at the receiver side antennas for deploying Line-of-Sight (LOS) communication in Satellite Communication (Satcom) by using machine learning algorithms to detect signals as accurately as possible and to reduce the time taken to steer the beam as well as complexity of operations if a standard beamforming algorithm was used. To implement this, the antenna array weights are pre-calculated for a number of beam directions and kept as a database which are given to a linear regression machine learning model. The signal weights that are calculated for each array element by using their progressive measured phase difference is due to the arriving signal, that are given as input to a linear regression model and the direction of arrival (DOA) of the signal is predicted. The curve fitted linear regression model can be implemented in real-time geostationary satellite communication systems to accurately intercept the signal of interest.
随着通信系统的发展,为了提高发射或接收天线的增益,对波束形成的需求也在增加。波束形成允许引导辐射能量与预期的方向选择有效。这项工作的主要重点是开发一种有效的方法,在接收机侧天线波束形成,通过使用机器学习算法尽可能准确地检测信号,以部署卫星通信(Satcom)中的视线(LOS)通信,并减少引导波束所需的时间以及使用标准波束形成算法时的操作复杂性。为了实现这一点,天线阵列的权重被预先计算了许多波束方向,并作为数据库保存,这些数据库被给予线性回归机器学习模型。利用每个阵列单元的逐级测量相位差计算出的信号权重是由于到达的信号,作为线性回归模型的输入,并预测信号的到达方向(DOA)。曲线拟合的线性回归模型可以在实时地球同步卫星通信系统中实现,以准确截获感兴趣的信号。

The signal weights that are calculated for each array element by using their progressive measured phase difference is due to the arriving signal, that are given as input to a linear regression model and the direction of arrival (DOA) of the signal is predicted. The curve fitted linear regression model can be implemented in real-time geostationary satellite communication systems to accurately intercept the signal of interest.","PeriodicalId":297285,"journal":{"name":"2020 4th International Conference on Electronics, Communication and Aerospace Technology (ICECA)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127066255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
