The drive for secure, open, and easily accessible voting systems has spurred the advance of decentralized blockchain-powered voting systems. This paper outlines the design and implementation of a decentralized voting system that utilizes the Hardhat Ether for testing and deployment, the Volta blockchain, Solidity smart contracts, and MetaMask for user interaction. Our approach ensures the confidentiality and integrity of votes by harnessing the irreversible and transparent properties of blockchain technology, enabling participation from any location with internet connectivity. Users can safely cast their ballots straight from their web browsers thanks to the inclusion of MetaMask, improving accessibility and usability. Furthermore, the application of Hardhat Ether simplifies the development process, enabling reliable deployment and testing protocols. This paper discusses the architecture, functionality, and security considerations of our decentralized voting system, highlighting its potential to revolutionize democratic processes worldwide. © 2024 IEEE.

Nowadays the social media has become one of the most essential platforms for reviewing and commenting their own opinions and perspectives. Sentiment analysis is the study of analyzing reviews of the people from texts, products and also analyzing the customer opinions. Expression or Sentiment analysis uses machine learning concepts particularly Natural Language Processing and various ML algorithms. Mining of the data helps to draw conclusions from various fields. We have proposed a paper where we analyze the sentiments of twitter data, identify and segregate positive tweets and negative tweets using machine learning and displaying the number of positive and negative tweets, plotting them using histogram and displaying the classification report. We have done this project since it is one of the most important tasks of classifying the positive and negative texts and analyze the sentiments which is very crucial for any organization's growth © 2024 IEEE.

Digital governor, which is a key control equipment for hydro power and pumped-storage power plants, is mostly designed and manufactured overseas. Therefore, when its parts are not produced or after service is terminated, it may be entirely replaced because spare parts and maintenance is not available. Moreover, the module test for diagnosing the governor controller cannot be effectively performed since it supply digital and analog signals to the modules in independent way. And also, it is difficult to analyze the output value for the input and the signals to drive the servo device. Therefore, this paper proposes fault diagnosis devices to perform offline test for governor controller of hydro power and pumped-storage power plants. And also, this paper presents the configuration and operation mechanism of the governor controller for 7MW hydro power and 250MW pumped-storage power plants and then implements diagnosis devices for digital governor controller of hydro power and pumped-storage power plants. From the test results according to the operation mechanism and diagnosis devices, it is confirmed that the proposed fault diagnosis devices can identify the normal operation characteristics for the governor controllers operated in the fields, and then the proposed devices are useful to diagnose fault in governor controllers of hydro power and pumped-storage power plants.

A requirement for expanding the C band of the satellite frequency band in the communication field has expanded along with C band usage due to the abundance of satellite resources and the rising demand for satellite communication. The suggested antenna design features a ground plane with triangular slot and a U-shaped patch. Microstrip antennas with slots benefit from features including low profile, simple construction, simple feeding, simple system integration, and, most importantly, higher gain. In this study, a microstrip patch antenna with a U-shaped radiating element and microstrip line feeding is proposed. Using CST Microwave Studio, one may design and parameterize. The antenna is made of FR-4 Lossy material, at which the dielectric constant and thickness are 4.3 and 1.6mm, respectively. The antenna has a 28mm∗28mm∗1.6mm size. According to simulations, the antenna's S11 (return loss) is -64.68 dB at 4.01 GHz, -10-dB impedance bandwidth is 59%, 3-dB axial ratio bandwidth is 12.84% at 4.01 GHz, and its VSWR is 1.01 at that frequency. © 2023 IEEE.

Cyberbullying is one of the new problems arising from the spread of social media throughout the past several years. The best way to ensure users' safety is to aggressively search for instances of cyberbullying and stop them right away. The basis of the present research is built from sophisticated language patterns used in cyberbullying, which beyond the reach of conventional machine learning methods. This paper proposes a fresh approach based on the properties of two recurrent neural networks to detect cyberbullying incidents. One of these networks feature extracting;the other has classification ability. This method is said to enable one to solve problems. This new approach efficiently extracts residual machine learning (RML) aspects using their features. Over numerous social media sites, the findings of an experimental investigation on the classification of cyberbullying writings reveal that the RML framework much surpassed its predecessors. The model performs better in memory, accuracy, and precision than more conventional methods about the challenging issue of cyberbullying. © 2024 IEEE.

An Efficient Autism Detection Using Structural Magnetic Resonance Imaging Based on Selective Binary Coded Genetic Algorithm

In this work, an efficient machine learning technique for autism diagnosis using structural magnetic resonance imaging (MRI) is proposed. The proposed technique employs the voxel-based morphometry (VBM) approach to extract a set of 989 relevant features from MRI. These features are used to train an efficient extreme learning machine (ELM) classifier to identify autism spectrum disorder (ASD) and healthy controls. The proposed selective binary coded genetic algorithm (sBCGA) found a subset of significant VBM features. The selected subset of features was used to build a final ELM classifier with maximum overall accuracy. The proposed sBCGA uses a selective sample-balanced crossover designed to improve the classification of ASD and healthy controls. The proposed sBCGA has been extensively tested, and the experimental results clearly indicated better accuracy than existing methods. © 2023.

In this study, a microstrip patch antenna for 5G communications is presented. Due to high demand for satellite communication, there is a requirement for expanding S - band, C-band & X-band of the satellite frequency in the communication industry. The proposed design consists of circular and square patch antenna with rectangular and circular slotting in ground plane. It operates for S-band and C-band at frequencies range of 2GHz to 12GHz. The Proposed antenna is designed on FR-4 (lossy) substrate with a loss tangent of 0.002 and a standard thickness of 1.6 mm. The Simulated Antenna gain achieved are 2.39dBi, 3.56dBi, 1.51dBi, 3.54dBi, 1.42dBi, 1.17dBi) with Return loss-27.92dB, -29.80dB, - 12.48dB, -18.83dB, -18.26dB, -20.87dB) operating at 2.1GHz, 2.5GHz, 2.8GHz, 3.3GHz, 3.7GHz, 4.6GHz respectively. The overall patch dimension is optimized to 28text{mm}{ast}37text{mm}. For excitation, the technique of Microstrip feeding is employed. The Defected Ground Structure technique is used for enhancing the gain of the proposed antenna. The defect disturbs the shielded current distribution which result in a controlled excitation and propagation of electromagnetic waves through substrate layer. This antenna design is simulated using CST Microwave Studio Software. © 2023 IEEE.

Maintaining optimal tip clearance or tip gap is challenging in the Gas Turbine Engine (GTE). Meanwhile, the rotor blades should not rub the casing. When the capacitive sensor is used to measure the tip clearance in the form of a single peak signal for every blade pass, often the signal will be affected by stationary and non-stationary noises during engine running. This leads to distorted multiple peaks for every blade pass. In this work, the wavelet denoising technique removes the noise, and then the peak frequency in each blade pass is detected through a short-time Fourier transform (STFT). Finally, the cubic spline interpolation technique is employed to obtain the continuous time domain blade pass signal. This work uses the compressor stage of GTE data collected from the Gas Turbine Research Establishment (GTRE), DRDO, Bangalore. From the experimental analysis, this paper observes that the proposed methodology produces substantial results compared to the expected results. © 2023 IEEE.
