Traditional methods, relying on physical sensors and manual inspections, often lack the ability to provide timely insights into emerging faults. In contrast, the surveyed approaches integrate non-contact vibration sensors with advanced machine learning techniques, revolutionizing fault detection capabilities. The study presents a brief overview of the methods used in classification of the rotating machinery defects using the machine learning and recommends a combination of machine learning methods at different stages to overcome the challenges of the traditional methods. The collected vibration signals undergo noise reduction via the Hilbert transform, followed by dimensionality reduction and feature selection using Independent Component Analysis (ICA) and Genetic Algorithms (GA), respectively. The selected features are then employed for fault detection and categorization using Random Forest (RF) and Deep Belief Networks (DBN). The Future work will involve the implementation and evaluation of these approaches in real-world industrial settings to validate their effectiveness and reliability.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"310 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140274031","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}

The objective of the research work is to demonstrate the feasibility of harnessing renewable energy sources in an underwater environment and showcase the potential for sustainable power generation. To ensure the structural integrity of the vehicle under water, rigorous simulation analysis has been conducted using ANSYS software. The hull design has undergone thorough scrutiny to determine its ability to withstand water pressure at depths of up to 5 meters. The simulation results confirm that the submarine's hull design is robust and capable of withstanding the expected operating conditions. This study holds great significance in the field of marine engineering as it explores alternative energy sources for underwater applications. By harnessing wave energy, this work contributes to the development of sustainable technologies that can potentially revolutionize underwater operations. The use of renewable energy sources minimizes environmental impact and reduces reliance on traditional power sources. Throughout this research, challenges were encountered, including optimizing the turbine system efficiency, ensuring reliable power transfer, and maintaining the structural integrity of the submarine. These challenges were addressed through careful design considerations and iterative improvements. The knowledge gained from this study can be applied to various underwater applications such as marine exploration, environmental monitoring, and data collection.

This study gives a general overview of the ring oscillator circuit, including its workings, uses, and important design considerations. The ring oscillator generates timing signals for synchronous operation and is often employed as a clock generator in digital systems. It may also be used as a frequency divider to separate higher frequencies into lower ones. A closed loop is used to connect an odd number of inverting stages to create the ring oscillator circuit. An inverter, which is often built using complementary metal-oxide-semiconductor (CMOS) technology, is a component of every stage. By adding a delay to each step, the ring oscillator creates a self-sustaining oscillation. The development and comparison of 3, 5, and 7 stage ring oscillators for different performance metrics, as well as corner analysis for propagation delay and the effect of temperature on the operation of the ring oscillator was performed using Cadence Virtuoso with 90nm technology. This comparison of several phases of a current-starved (CS) ring oscillator offers an advantage to the best design with innovation based on the technology employed and outcomes from the corner analysis, which hasn't been done in any of the more recent researches.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135686463","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}

In this work an antenna array is designed and integrated with RF MEMS shunt capacitive switch over it, for the applications of S,C,X-band in the frequency range of 2-12GHz. A membrane that can move freely over a coplanar waveguide serves as the MEMS switch. Here, a double meander tuned dual beam arrangement is used to increase switch isolation. Electrostatic mechanisms are used for actuators due to their low power requirements, compact design, and quick switching. By the simulation result, The beam starts to bend from 0.60793mm to 0.4116mm at the voltage 1.78492mV to 57.7382mV and it provides capacitance at 1.435pF to 1.597nF. It was noticed that the insertion loss (S21) and the return loss (S11) of a MEMS switch are around -0.079 dB and 20.618 dB correspondingly, in order to have a good switching characteristic in the up state. The switch has an insertion loss (S21) of -31.307 dB and return loss (S11) of about -0.256 dB in the up state thus exhibiting good switch characteristics. The RF MEMS shunt capacitive switch is integrated on the predesigned antenna array the dynamically shifting of the switch from on state to off state helps achieving the reconfigurability in the antenna array. Such antennas are applicable in spaceborne radar, communication satellites, unmanned aerial vehicles, unmanned aircraft system and various other communication as well as sensing applications.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"377 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135737545","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}
