This article presents the effect of a precise wind turbine system (PWTS) and accurate model of HVDC link on multi-area AGC systems. The proposed system comprises one thermal and PWTS unit in all the areas. A novel secondary controller known as tilt-integral-double derivative (TIDD) has been developed. In order to fine-tune the controller and other variables, the bird swarm algorithm (BSA) has been used effectively. The comparison of system dynamics responses with PID, TID, and TIDD controller concluded that the system with TIDD outperformed. The study of PWTS integration on system dynamics concluded that PWTS improves the system’s dynamic performance.

DC micro grid provides power locally with minimum transmission losses. However, due to presence of converters, dc micro grid suffers from the nonlinearities which led to instability of the system. It imposes challenge to integrate dc micro grid with the distribution network. Therefore, in this paper, the transient stability of the DC microgrid has been investigated considering linear load, nonlinear load, nonlinear load with DG and pole to ground fault. Due to the high-order and nonlinear nature of the dc microgrid system, the nonlinear decoupling method has been adopted for a more efficient analysis of the transient stability of dc microgrids. The nonlinear decoupling technique can resolve nonlinear difficulties, which is extremely appropriate for the transient stability assessment of dc microgrids. From the results, it is observed that in the case of nonlinear loads, the introduction of DG as an active power compensation in the system can considerably improve the overall active power in the system. Also, in case of fault, DG works as a backup and supplies power to the load. The simulation results also reflects that in some circumstances, adding and removing large loads and changes in voltage levels are not invertible. One of these changes in system dynamics could result in system instability.
直流微电网以最小的传输损耗就地供电。然而,由于变流器的存在,直流微电网存在非线性,导致系统不稳定。直流微电网与配电网的整合提出了新的挑战。因此,本文研究了考虑线性负荷、非线性负荷、含DG的非线性负荷和极地故障的直流微电网暂态稳定性。由于直流微电网系统的高阶和非线性特性,为了更有效地分析直流微电网的暂态稳定性,采用了非线性解耦方法。非线性解耦技术可以解决非线性问题,非常适用于直流微电网暂态稳定评估。从结果可以看出,在非线性负载情况下,引入DG作为系统有功功率补偿,可以显著提高系统整体有功功率。同时,在发生故障时,DG作为备用电源,为负载供电。仿真结果还反映了在某些情况下,大负荷的增加和减少以及电压水平的变化是不可逆的。系统动力学中的这些变化之一可能导致系统不稳定。

Deep learning is attracting tremendous prominence as an adequate replacement for i-vectors in the speaker identification task. Deep neural networks have attained much attention in the end-to-end (E2E) speaker identification domain. Earlier, DNN trained on handcrafted speech features like Mel-filter banks and Mel-frequency cepstral coefficients. Later, as the raw speech signal is lossless, processing raw waveforms have become an active research area in E2E speaker identification, automatic music tagging, and speech recognition fields. Convolutional neural networks (CNNs) have recently shown promising results when fed directly with raw speech samples. CNN analyzes waveforms to discover low-level speech representations rather than conventional handcrafted features, which may enable the system to handle speaker properties like pitch and formants more efficiently. An efficient design of neural networks is vital to achieving this. The CNN architecture proposed in this paper promotes the deep convolutional layers to develop more efficient filters for end-to-end speaker identification systems. The proposed architecture converges quickly and outperforms conventional CNN on raw waveforms. This research work has been tested on the Librispeech dataset and improved the Speaker identification accuracy by 10% and decreased the validation loss by 32%.
深度学习在说话人识别任务中作为i-向量的适当替代品而引起了极大的关注。深度神经网络在端到端说话人识别领域受到广泛关注。早些时候,深度神经网络在手工制作的语音特征上进行训练,比如mel滤波器组和mel频率倒谱系数。后来,由于原始语音信号是无损的,对原始波形的处理成为端到端说话人识别、音乐自动标注、语音识别等领域的研究热点。卷积神经网络(cnn)最近在直接输入原始语音样本时显示出了令人鼓舞的结果。CNN通过分析波形来发现低级语音表征,而不是传统的手工特征,这可能使系统能够更有效地处理音高和共振峰等扬声器属性。有效的神经网络设计对于实现这一目标至关重要。本文提出的CNN架构促进了深度卷积层,为端到端说话人识别系统开发更有效的滤波器。所提出的架构收敛速度快,在原始波形上优于传统的CNN。该方法在librisspeech数据集上进行了测试,结果表明,该方法的说话人识别准确率提高了10%,验证损失减少了32%。

Quantum computing is a fast-emerging field that follows the laws of quantum mechanics to solve complex problems for classical systems. In the last few years, several researchers have emerged in quantum computing in accordance with the artificial intelligence field. Natural language processing is one of the prominent subfields of artificial intelligence. Quantum computing can be applied to the applications of natural language processing for better performance. One of the vital applications of natural language processing is Parts-Of-Speech (POS) tagging. It is prerequired for many natural language processing applications. In this paper, we have performed POS tagging of the Mizo language using classical Long short-term memory (LSTM). Subsequently, quantum-enhanced long short-term memory (QLSTM) has also been used to perform POS tagging of the Mizo language. The approaches mentioned above have been tested on the Mizo-tagged corpus, and experimental results have shown that quantum computing approaches such as QLSTM need the inclusion of new technologies to achieve significant results.

Social networking services have emerged as the main sources for real-time information about events happening. It has been observed that pertinent information gleaned from tweets during catastrophic events can be helpful in a variety of ways. Therefore, it is necessary to create an automated microblog summarization system. The proposed approach JOWTS, confluence of a wide range of evolutionary computation techniques such as the well-known differential evolutionary algorithm JADE (DE/current-to-pbest/1), Opposition-based Learning (OBL) and Whale Optimization Algorithm (WOA), employs multi-objective optimization for microblog summarization. The summarization task is formulated as a multi-objective optimization problem and combination of objectives such as tweet length & importance of tweets (through tf-idf technique) in a dataset are optimized at the same time. For evaluation, datasets relevant to disaster events are employed and the results are compared to different alternative methodologies utilizing ROUGE measures. When compared against the contemporary evolutionary techniques, it was observed that JOWTS improves ROUGE-1, 2, L scores by 3.86%, 8.53% and 4.69% respectively.

Age-related Macular Degeneration (AMD) is a retina macular degenerative disease that affects elderly persons. Diagnoses of AMD can be accomplished via manual inspection of typical fundus images. But physicians are limited in their ability to process the full extent of data fundus images provide and their diagnoses are subject to differences in interpretation. This paper proposes an image processing algorithm using a lightweight convolution neural network to improve speed and standardization in AMD diagnosis. The first step in lightweight CNN is a feature extraction algorithm that automatically processes a fundus image to extract important retinal features. In the second step, the proposed method classifies the AMD based on the features extracted in the first step. The proposed network has been trained and tested with STARE and RFMiD fundus databases available publicly. The proposed network has obtained 97.39% and 98.97% accuracy with STARE and RFMiD databases, respectively. The results indicate that the proposed model is lightweight and is better than other state-of-the-art techniques, taken for considerations.

In today’s tech world, there are several crowdfunding platforms that enable both investors and organizations with a smooth flow of transactions, creating a huge hype in the market. However, security concerns and a fear of fraud are the biggest blow suffered by users on such networks. The history of crowdfunding platforms demonstrates the massive frauds that the public has been subjected to in recent years. This paper provides a completely decentralized method for creating a crowdfunding platform over the Ethereum Blockchain in the proposed system. A lot of attention has been attracted by Blockchain technology as a result of the rise of cryptocurrencies and decentralized apps. A common paradigm among them is the newly emerging Blockchain-based crowdfunding, which eliminates centralized cloud servers and uses smart contracts to fulfill each and every transaction. Blockchain, a promising decentralized paradigm, can be used to provide technological advancements like decentralization and accountability in addition to fixing the problems with current crowdfunding methods. The fundamental objective of the solution is to encourage accountability, transparency, and traceability for all stakeholders so that they always have complete control over their investments.
在当今的科技世界里,有几个众筹平台使投资者和组织都能顺利进行交易,在市场上制造了巨大的炒作。然而,安全担忧和对欺诈的恐惧是此类网络用户遭受的最大打击。众筹平台的历史证明了近年来公众遭受的大规模欺诈。本文提供了一种完全去中心化的方法,在提议的系统中创建以太坊区块链上的众筹平台。由于加密货币和去中心化应用程序的兴起,区块链技术吸引了很多关注。其中一个常见的范例是新兴的基于区块链的众筹,它消除了集中式云服务器,并使用智能合约来完成每笔交易。区块链是一个很有前途的去中心化范例,除了解决当前众筹方法的问题外,还可以用来提供去中心化和问责制等技术进步。解决方案的基本目标是鼓励所有涉众的问责制、透明度和可追溯性,以便他们始终完全控制他们的投资。

The advent of Radio Frequency Identification (RFID) applications has gained a lot of attention recently among manufacturers, developers and end-users. In essence, RFID has touched a wide range of identification, item tracking and sensing applications. However, because of the high cost of silicon-based integrated circuits, Chipped RFID’s widespread adoption is sometimes hampered.This problem may be solved by creating design approaches and strategies for improving performance for Chipless RFID implementation.This article goes through a handful of the key applications that Chipless can directly support.
