Ratnakar Nutenki, Aditya Thatipudi, Anil Kumar Perikala, Harshita Medida
Arc faults in electrical systems pose significant safety risks, and their early detection is crucial for preventing fires and other hazards. Traditional methods for arc fault detection in power systems often rely on conventional signal processing techniques, which may lack robustness and accuracy, especially in noisy environments. In this study, we propose a novel approach for arc fault detection using Mel-frequency cepstral coefficients (MFCCs) extracted from current signals generated by both arc and non-arc faults. MFCCs have been widely used in speech and audio processing due to their ability to capture relevant spectral features. In this paper we aim to investigate how MFCCs can differentiate between arc and non-arc faults in electrical systems. By analyzing the MFCC features extracted from current waveforms during both fault and non-fault conditions, to identify unique patterns and characteristics associated with arc faults.
电力系统中的电弧故障具有极大的安全风险,及早发现对防止火灾和其他危险至关重要。传统的电力系统电弧故障检测方法通常依赖于传统的信号处理技术,这些技术可能缺乏鲁棒性和准确性,尤其是在噪声环境中。在本研究中,我们提出了一种利用从电弧和非电弧故障产生的电流信号中提取的梅尔频率共振频率 (MFCC) 进行电弧故障检测的新方法。由于能够捕捉相关的频谱特征,MFCC 已广泛应用于语音和音频处理。本文旨在研究 MFCC 如何区分电气系统中的电弧故障和非电弧故障。通过分析从故障和非故障条件下的电流波形中提取的 MFCC 特征,找出与电弧故障相关的独特模式和特征。

A Novel approach for formation of Dense Clusters by Outlier Elimination and Standard Deviation 通过消除离群值和标准偏差形成密集聚类的新方法
Pushkar Joglekar, Tejaswini Katale, Aishwarya Katale, Surabhi Deshpande, Aarya Nirgude, Aakash Chotrani
Outliers are the uncommon data points which deviate from the majority of the Data from a dataset. Presence of Outliers can affect the model’s performance, leading to incorrect data analysis. Hence, identifying and eliminating Outliers is a crucial pre-processing step. This research paper suggests a method for removing outliers that takes standard deviation into account. Standard Deviation is a statistical measure which measures the dispersion within the dataset. In the proposed algorithm, the first step is to calculate Standard Deviations of all the features within the Dataset. Next, the feature with highest Standard Deviation is chosen. After normalization of this column, individual Standardized values for the data points are calculated from the standardized Median. Furthermore, these values are arranged in the ascending order. Selecting closest left 85% and right 85% values from the Standardized Median. For the remaining features, only those observations are selected which are corresponding to the above selected range of data points. To check the efficacy of this algorithm, it is implemented on 5 Standard datasets - Iris Species, Pima Diabetes Dataset, College Dataset, Seattle Weather, Water Quality Dataset. After elimination of Outliers, the proposed algorithm aims to form dense clusters. When compared with K-means clustering, for all the 5 datasets, it gives a better Silhouette Score. The highest score of 0.7 is for Iris Species and the highest difference of 0.49 between the Silhouette score of K-means and the proposed algorithm is for Water Quality Dataset.
异常值是指偏离数据集中大多数数据的不常见数据点。异常值的存在会影响模型的性能,导致错误的数据分析。因此,识别和消除异常值是一个关键的预处理步骤。本研究论文提出了一种将标准偏差考虑在内的消除异常值的方法。标准偏差是一种统计量,用于衡量数据集内部的离散程度。在建议的算法中,第一步是计算数据集中所有特征的标准偏差。然后,选择标准偏差最大的特征。对这一列进行归一化处理后,根据标准化中值计算出数据点的各个标准化值。此外,这些值按升序排列。从标准化中值中选择最接近的左侧 85% 和右侧 85% 值。对于其余特征,只选择与上述所选数据点范围相对应的观测值。为了检验该算法的有效性,我们在 5 个标准数据集上实施了该算法--鸢尾物种、皮马糖尿病数据集、大学数据集、西雅图天气和水质数据集。在剔除异常值后,该算法旨在形成密集的聚类。与 K-means 聚类相比,在所有 5 个数据集上,该算法都能给出更好的剪影得分。虹膜物种的剪影得分最高,为 0.7;K-means 算法和拟议算法的剪影得分之差最高,为 0.49。

Within the framework of a rapidly expanding worldwide population and the critical need to guarantee food security, precision agriculture has arisen as a crucial area of study and advancement. In the scope of this field, our research aims to make a significant impact by enhancing the evaluation of onion smut disease severity through an innovative multiclassification framework. The present study presents a new hybrid model that combines the strengths of Convolutional Neural Networks (CNN) and Random Forest (RF). This model integrates the feature extraction capabilities of deep learning (DL) with the classification robustness of ensemble learning, resulting in a synergistic approach. The combination of many elements leads to the development of a model that not only exceeds current benchmarks but also establishes a notable standard, demonstrating an outstanding overall accuracy rate of 96.38%. The significance of our model extends beyond its exceptional accuracy. The feature interpretability of this confers a significant advantage, as it enables a comprehensive comprehension of the various aspects that contribute to the severity of the condition. The availability of interpretability in this context provides farmers and agricultural specialists with a powerful tool that can significantly enhance their ability to make informed decisions based on data when it comes to managing diseases. Our research represents a groundbreaking advancement in the field of multiclass categorization in the context of agriculture. The historical constraints given by the complexity and diversity of crops and illnesses have been significant. However, our hybrid approach presents a scalable alternative that surpasses the limitations of traditional onion farming. Not only does it offer the potential for improved disease evaluation, but it also establishes a precedent for addressing multiclass classification jobs in the agricultural domain on a wider scale.

Analysis Of Data Forwarding Issues In Wireless Networks Aimed For Railway Signaling Systems 铁路信号系统无线网络数据转发问题分析
Jahnavi Katragadda, Mubeena Shaik, Seetha Ramanjaneyulu B
Due to the difficulties faced with wire-based signaling systems, wireless communication based signaling systems are gaining importance worldwide. While the cellular communication based systems like GSM-R and LTE-R were proposed in majority of the cases, the non-cellular communication systems that are based on adhoc networks and wireless sensor networks have also become equally important. In this later case, routing protocols like AODV are needed to forward the data packets when destination is not reachable directly from the source. In this context, if some improvements are made to these protocols to make it more suitable to these environments, it can help to have better performance. These aspects are studied and analyzed in this work by carrying out the simulation studies for the model network considered for railway signaling application. Results suggest that making use of GPS and keeping the alternate route on hand can improve the performance considerably. Omnet++ simulator with INET framework is used to carry out the simulations.
由于有线信令系统所面临的困难,基于无线通信的信令系统在全球范围内正变得越来越重要。虽然 GSM-R 和 LTE-R 等基于蜂窝通信的系统在大多数情况下都被提出,但基于 adhoc 网络和无线传感器网络的非蜂窝通信系统也变得同样重要。在后一种情况下,需要使用 AODV 等路由协议,在无法直接从源网络到达目的地时转发数据包。在这种情况下,如果对这些协议进行一些改进,使其更适合这些环境,将有助于提高其性能。本研究通过对铁路信号应用的模型网络进行仿真研究,对这些方面进行了研究和分析。结果表明,利用 GPS 和保留备用路线可以大大提高性能。仿真使用了带有 INET 框架的 Omnet++ 仿真器。

Rudresh Pillai, Neha Sharma, Deepak Upadhyay, Sarishma Dangi, Rupesh Gupta
Music genres, with their diverse sonic landscapes and distinct characteristics, have been a subject of profound interest in audio analysis. This research investigates the application of digital image processing in the field of music genre classification, utilizing Mel spectrogram images obtained from audio files. This study employs a sequential approach to analyze the 'GTZAN Dataset,' which consists of 10,000 documented Mel spectrogram images that represent ten distinct music genres. The dataset was partitioned in a systematic manner into three separate segments. This partitioning allowed for thorough training and evaluation of the model, with a distribution ratio of 60% for training, 20% for validation, and 20% for testing. The sequential model, which is based on deep learning tenets effectively captures complex genre-specific characteristics from Mel spectrograms in order to achieve accurate music genre categorization. By utilizing a dataset consisting of 6,000 training photos and 2,000 validation photos, the model's parameters underwent refinement. Subsequently, an evaluation was conducted on a distinct set of 2,000 test photographs, which unveiled a remarkable accuracy rate of 94%. During the course of the research, performance metrics such as accuracy and loss graphs were employed to monitor the learning progress of the model during the training phase. Moreover, the examination of the confusion matrix in the testing phase provided insight into the effectiveness of the model, resulting in notable performance measurements. This confirms the model's strength in accurately categorizing music genres. This research makes a substantial contribution towards the advancement of autonomous systems that possess the ability to accurately classify music genres by utilizing spectrogram representations. The model's accuracy of 94% serves as evidence of its effectiveness, indicating its possible applications in systems for recommendations, music indexing, and content organization. This emphasizes its significant contribution to the field of audio content analysis and classification approaches.
音乐流派具有不同的声音景观和鲜明的特征,一直是音频分析领域深感兴趣的课题。本研究利用从音频文件中获取的梅尔频谱图图像,研究数字图像处理在音乐流派分类领域的应用。该数据集由 10,000 张记录的梅尔频谱图图像组成,代表了十种不同的音乐流派。该数据集被系统地划分为三个独立的部分。这种划分方式有助于对模型进行全面的训练和评估,训练、验证和测试的分配比例分别为 60%、20% 和 20%。基于深度学习原理的序列模型能从梅尔频谱图中有效捕捉复杂的特定流派特征,从而实现准确的音乐流派分类。通过使用由 6000 张训练照片和 2000 张验证照片组成的数据集,该模型的参数得到了改进。随后,在由 2,000 张测试照片组成的不同数据集上进行了评估,结果显示准确率高达 94%。在研究过程中,采用了准确率和损失图等性能指标来监控模型在训练阶段的学习进度。此外,在测试阶段对混淆矩阵的检查也有助于深入了解模型的有效性,从而得出显著的性能指标。这证实了该模型在准确划分音乐类型方面的优势。这项研究为推动自主系统的发展做出了重大贡献,这些系统具备利用频谱图准确分类音乐类型的能力。该模型高达 94% 的准确率证明了它的有效性,也表明了它在推荐、音乐索引和内容组织系统中的应用可能性。这强调了它对音频内容分析和分类方法领域的重大贡献。

By utilizing a dataset consisting of 6,000 training photos and 2,000 validation photos, the model's parameters underwent refinement. Subsequently, an evaluation was conducted on a distinct set of 2,000 test photographs, which unveiled a remarkable accuracy rate of 94%. During the course of the research, performance metrics such as accuracy and loss graphs were employed to monitor the learning progress of the model during the training phase. Moreover, the examination of the confusion matrix in the testing phase provided insight into the effectiveness of the model, resulting in notable performance measurements. This confirms the model's strength in accurately categorizing music genres. This research makes a substantial contribution towards the advancement of autonomous systems that possess the ability to accurately classify music genres by utilizing spectrogram representations. The model's accuracy of 94% serves as evidence of its effectiveness, indicating its possible applications in systems for recommendations, music indexing, and content organization. This emphasizes its significant contribution to the field of audio content analysis and classification approaches.","PeriodicalId":518900,"journal":{"name":"2024 Fourth International Conference on Advances in Electrical, Computing, Communication and Sustainable Technologies (ICAECT)","volume":"44 2","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140531568","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}

Kireet Joshi, V. K. Gupta, Paras Jain, Anurag Shukla, Monika Bharti, Himanshu Jindal
The disease prediction system predicts the disease by taking symptoms from the user and predict using machine learning algorithms that whether the user has disease or not. The proposed model supports the user-friendly interface and is easy to handle and performs operations accordingly. It is built to help the people at early stage to check the presence of disease, producing the results with an accuracy of almost 86% for Parkinson's disease, 97% for Gestational disease and 85% for cardiovascular disease. Our methodology is performing better in comparison of existing methods, where we have developed one algorithm for the same. The dataset of various patients related to this disease is taken from Kaggle websites. We represented our results with various diagrams and charts as well.

Enhanced scanning rate for SIW-LWA with continuous beam steering using delay lines 利用延迟线提高 SIW-LWA 连续光束转向的扫描速率
R. Agarwal, Himanshu Kumar, Himanshu Mishra
A backward-to-forward continuous beam scanning leaky wave antenna (LWA) in substrate integrated waveguide (SIW) technology using delay lines is demonstrated in this study. A periodical H-shaped grooves on the top surface of SIW are etched to provide the slow-wave effect. Delay lines is introduced to change the group delay profile, increasing the SR. According to simulations, the presented LWA scans a broad angle in a limited bandwidth. Within the frequency range of 11.6 GHz to 12.3 GHz, scanning angle ranging from -41° to +31° (overall scanning angle of 72°) with scanning rate of 90°/GHz. This antenna has maximum gain of 14.53 dBi at 11.9 GHz and 92.5% efficiency, which is acceptable considering the antenna’s compact size.
