Rajni, C. Rai
This paper incorporates a ℓ0 –norm sparsity constraint into variable step size normalized least mean square (ℓ0 -VSSNLMS) algorithm for identification of sparse system corrupted by additive noise. The proposed ℓ0–VSSNLMS algorithm makes a good fairness between convergence characteristics, filter stability and steady state error. The proposed (ℓ0 -VSSNLMS) algorithm incorporates a variable step size that accelerates the convergence characteristics and lowers the mean square deviation (MSD) error than in ℓ0 - NLMS with constant value of step size. The inclusive theoretical performance of ℓ0 -VSSSNLMS algorithm is analyzed in this paper with white Gaussian input under some assumptions which are suitable for practical purpose. An expression for variant step size is derived under the stability condition of proposed algorithm. Finally the implementation of the proposed algorithm is carried out in MATLAB software to manifest the improved beavior in identification of sparse system.

Simulative Investigation of Wireless Sensor Network with the Deployment of Different Number of Nodes 不同节点数无线传感器网络的仿真研究
R. Kaur, Parveen Singla, Rinkesh Mittal
Wireless networks consists of several nodes which require individual battery or power supply for the purpose of operation. These active nodes lose their respective energy during their respective operations such as to provide communication between various nodes. So, in modern communication system, recharge and replacement of such nodes or their batteries is a challenging task due to their deployment in the remote places. Thus, to get efficient routing criteria and to increase the efficiency of WSN is a major challenging task for researchers, therefore a large number of researches have worked on the concept to increase the lifespan and efficiency of WSNs with different routing protocols. However, there are still a number of issues that require further analysis and investigation. For the purpose of sending and sensing of data, LEACH protocol is one of the widely used protocols and algorithm. The proposed algorithm or technique use cluster forming technique which is based on formation of several clusters during different events, cluster head selection, aggregation of the efficient and sensed data within desired cluster and sending that particular data to base station in a manner to maintain both energy and efficiency of system. In this paper, we analyzed the complexity of entire networks in the terms of various packet send to BS, number of dead nodes created during the operation and sum of energy of several nodes of entire network. Several experimental results are carried out to show the complexity of packets, detection of dead nodes and energy of network with different number of nodes.
无线网络由几个节点组成,这些节点需要单独的电池或电源来运行。这些活动节点在各自的操作过程中失去各自的能量,例如在各个节点之间提供通信。因此,在现代通信系统中,这些节点或其电池由于部署在偏远地区,充电和更换是一项具有挑战性的任务。因此,获得有效的路由准则并提高无线传感器网络的效率是研究人员面临的一个重大挑战,因此大量的研究工作都是在不同路由协议下提高无线传感器网络的寿命和效率。然而,仍有许多问题需要进一步分析和调查。为了实现数据的发送和感知,LEACH协议是目前应用最广泛的协议和算法之一。所提出的算法或技术采用基于在不同事件期间形成多个簇,簇头选择,在所需簇内聚集有效和感知的数据并以保持系统能量和效率的方式将特定数据发送到基站的簇形成技术。在本文中,我们从发送到BS的各种数据包、运行过程中产生的死节点数量以及整个网络中几个节点的能量总和等方面分析了整个网络的复杂性。实验结果显示了不同节点数下的数据包复杂度、死节点检测和网络能量。

Stock Market Prediction using Machine Learning Algorithms: A Classification Study 使用机器学习算法预测股票市场:分类研究
Meghna Misra, Ajaykumar Yadav, Harkiran Kaur
Predicting the stock market has been an area of interest not only for traders but also for the computer engineers. Predictions can be performed by mainly two means, one by using previous data available against the stock and the other by analysing the social media information. Predictions based on previous data lack accuracy due to changing patterns in the stock market al.so, some fields might have been missed due to their insignificance in some stocks or unavailability of data. For example, some models may require ‘return rate’ as a parameter for stock prediction, but the available data might not have it. On the other hand, a model predicting only on the basis of the return rate may find opening and closing price to be insignificant parameters. The data has to be cleansed before it can be used for predictions. This paper focuses on categorising various methods used for predictive analytics in different domains to date, their shortcomings. Further, the authors of this paper have suggested some improvements that could be incorporated to achieve better accuracy in these approaches.
预测股市不仅是交易员感兴趣的领域,也是计算机工程师感兴趣的领域。预测主要可以通过两种方式进行,一种是通过使用以前的股票数据,另一种是通过分析社交媒体信息。由于股票市场模式的变化,基于先前数据的预测缺乏准确性。因此,一些领域可能由于在某些股票中不重要或无法获得数据而被遗漏。例如,一些模型可能需要“回报率”作为股票预测的参数,但可用的数据可能没有。另一方面,仅根据收益率进行预测的模型可能会发现开盘价和收盘价是无关紧要的参数。数据必须经过清理才能用于预测。本文着重对迄今为止不同领域中用于预测分析的各种方法进行分类,以及它们的缺点。此外,本文的作者还提出了一些改进建议,可以纳入这些方法以获得更好的准确性。

Analysis and Design of Discharging Circuit for Auxiliary Battery Systems in EVs 电动汽车辅助电池系统放电电路分析与设计
M. K. Reddy, S. Gunturi, D. Elangovan
This paper deals with designing a simulation model of test setup for deriving information for analyzing the discharging characteristics of a battery in accordance with a predefined discharging profile. As an initial step, in order to determine the parameters from the discharging circuit, the requirements of the batteries were collected. A DC-DC boost converter of 4 kW input power and maximum input current of 100 A is designed for discharging the source battery in a controlled manner using PI controller. From a variable input voltage, boost converter is able to step-up the input voltage to a higher constant dc output voltage using feedback technique. The resistive load is used initially and later the dc motor load is used as a variable load. The constant output voltage of 50 V is obtained. The simulation is done using MATLAB/ SIMULINK. The final outcomes are determining the suitable loads for discharging battery and obtaining the regulated output voltage.

Finally with these features testing is conceded for linear and dynamic loading.","PeriodicalId":393891,"journal":{"name":"2018 International Conference on Recent Innovations in Electrical, Electronics & Communication Engineering (ICRIEECE)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126645011","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}

Comparison of ANFIS and ANN Techniques in Fault Classification and Location in Long Transmission Lines ANFIS与ANN技术在长距离输电线路故障分类定位中的比较
S. Panda, D. Mishra, S. Dash
This paper presents application of ANFIS and ANN in fault classification and location in a long transmission line. Compared to other methods, Machine Learning techniques based on artificial intelligence perform the best in fault classification and finding its location. Most frequently used ML techniques for this purpose are ANFIS and ANN. Both the techniques were able not only to identify fault type but also to find the fault location in the transmission line very accurately using source end current and voltage data. Common training and testing data was used for ANFIS and ANN. This data was obtained from simulation of faults in a long transmission line model using MATLAB. Error analysis and comparison of both the techniques is also presented in this paper. A GUI was designed for comparison of both the methods.
本文介绍了人工神经网络和人工神经网络在长输电线路故障分类定位中的应用。与其他方法相比,基于人工智能的机器学习技术在故障分类和定位方面表现最好。为此目的最常用的ML技术是ANFIS和ANN。这两种方法不仅能够准确地识别故障类型,而且能够利用源端电流和电压数据准确地定位故障在输电线路中的位置。ANFIS和ANN使用通用的训练和测试数据。该数据是利用MATLAB对某长传输线模型的故障进行仿真得到的。本文还对两种技术进行了误差分析和比较。设计了GUI来比较两种方法。
