Electric vehicles (EVs) acts an essential role in the decarbonization of transportation and overall efforts to reduce greenhouse gas emissions. EV creates zero tailpipe emissions, as they are powered by electricity rather than fossil fuels. This directly contributes to reducing local air quality improvement, particularly in metropolitan areas, and contaminants in the air where emissions from conventional vehicles are a significant concern. This paper presents a novel approach for optimizing EV performance by employing a cascaded ANFIS based MPPT technique in conjunction with a high-gain SEPIC-Zeta converter. The proposed high gain converter offers advantages such as high voltage gain, reduced input current ripple and improved voltage conversion efficiency. The cascaded architecture of the ANFIS-based MPPT technique provides enhanced tracking accuracy, robustness and adaptability to varying environmental factors including temperature changes and sun irradiation. By dynamically adjusting the operating point of the PV array, the system ensures that the EV battery receives the maximum available power from the PV source, resulting in increased energy harvesting efficiency. The optimized power conversion process achieved through the cascaded ANFIS-based MPPT and high-gain SEPIC-Zeta converter contributes to the advancement of EV technologies, promoting sustainable and efficient transportation systems.

Plant diseases often lead to significant agricultural losses, causing economic difficulties and food shortages. Conventional detection approaches are inefficient, challenging, and must have expert engagement, resulting in decreasing scalability. Recent developments, including machine learning and IoT-integrated systems, have enhanced real-time monitoring;However, they encounter obstacles such as restricted generalization to varied environmental circumstances, data imbalance, and insufficient adaptability to uncharacteristic diseases. This research tackles these issues by introducing an IoT-Enhanced Convolutional Neural Network (CNN) integrated with a One-Class Support Vector Machine (SVM). The model utilizes IoT for real-time data collection, CNN for effective feature extraction, and One-Class SVM for anomaly identification. Experimental results indicate the system's exceptional performance, attaining 95.6% accuracy, a 3.4% lower rate of false positives, and 97.2% precision, offering a scalable, automated solution for early disease detection, minimizing crop losses, and enhancing agricultural sustainability. © 2024 IEEE.

In our rapidly expanding world, there is a rising demand for low-cost, long-lasting, and less dangerous medicinal products. Medical items ranging from intravenous fluid containers to medical syringes are created to satisfy their demands using a range of thermoplastics and Plastic Injection Moulding (PIM). However, even advanced profile mouldings can suffer from dimensional inaccuracies. The current study advances our understanding of thermoplastics, specifically Low-Density Polyethylene (LDPE) material moulding for medical syringe plungers using injection moulding equipment. Eight injection moulding input factors were investigated in order to decrease the depth sink marks and weight created during the injection moulding of thermoplastic LDPE material. The 27 trials were piloted in accord with Taguchi's Design of Experiment, and the variables were optimised using the newly developed Honey Badger and Capuchin Search Algorithms, as well as analysis of variance, for determining the most dominating parameter. The cooling time and melt temperature of the plastic injection moulded part are the most significant factors influencing the sink-mark depth and weight of the part, respectively, according to the Analysis of Variance (ANOVA) test. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

The gudgeon pin is one of the engine's most stressed components. Gudgeon pins are used in automotive engines to link the piston and connecting rod. Stress concentration is a critical concern in the design of mechanical components, as it can lead to premature fatigue failure and, consequently, catastrophic consequences. To mitigate this risk, engineers continually seek ways to optimize the design of components like the gudgeon pin, and one avenue of exploration is the judicious choice of materials. This study looks at the detailed design and analysis of existing gudgeon pins in order to detect the pin's stress concentration and then minimize it by making necessary changes to the pin's design and mounting. The current work involved constructing a gudgeon pin and then using finite element analysis (FEA) software to examine and minimize stresses on the pin. This comprehensive study delves into the intricate world of gudgeon pin design and analysis, with a specific emphasis on minimizing stress concentration by selecting different materials through FEA. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In recent years, the installation of renewable energy facilities has grown rapidly due to the movement to reduce greenhouse gas emissions and preserve fossil fuels. Hence, the use of Electric vehicles (EV) are becoming more prevalent, making it necessary to improve and expand charging infrastructure. Hybrid renewable energy source (HRES) is needed for EV charging stations because the stored energy in an EV battery is insufficient for long distance travel. In this work, the concept of EV charging stations that are capable of being integrated with renewable energy sources (RES) and energy storage devices is proposed. Since the output from fuel cell and Photovoltaic (PV) system are intermittent due to environmental conditions, DC-DC converter is required to enhance voltage. Hence, Boost and improved Cuk converter is employed to improve voltage attained from fuel cell and PV system respectively. A single phase voltage source inverter (1 VSI) assists in the conversion of the DC link voltage to AC voltage, which is subsequently delivered to the EV battery for further usage. The AC power is then supplied to the grid. Internet of Things (IoT) is employed for remote monitoring and control purposes by sending vital data to cloud, in which the parameters such as DC link voltage and State of Charge (SOC) of battery is monitored. The MATLAB Simulink software is used to run all of the components and produce the appropriate results. It is clear from these results that the new approach is 97% more efficient than the traditional approaches.

Modern digital technology breakthroughs include machine learning. It's used in medical, image processing, manufacturing, aviation, autonomics, and more. Our main goal is to find an automated system that can accurately rate production machines at any given moment. The critical energy meter characteristics needed to create power reports in automation system to solve production difficulties at defined intervals were also not captured. We apply machine learning to estimate manufacturing machine accuracy in this study. We employed supervised machine learning of binary decision tree using CART method and power report, obtained data using RS232 to RS485 convertor through Modbus communication protocol, to overcome these challenges. This study presents issue formulation, energy meter data analysis and retrieval, and ML approaches used to estimate production machine accuracy.

Electrical Discharge machining (EDM) is an emerging solution for the precise machining of the commercial metals and alloys. In EDM, machining is performed by the heat input with the successive electrical spark between the electrode and work piece. Hence surface texture of the materials changes after the machining process due to this too much heat input. Thus, surface texture depends on the variation of heat input during the process. In present work, galvanized mild steel (GMS) is machined by EDM at different current values (5 A, 10 A, 15 A and 20 A) for studying the effect of heat input on the surface texture. In addition, corrosion behaviors of GMS samples machined by EDM at different currents have been studied in 0.5 M NaCl by open circuit potentials (OCP), polarization curves and electrochemical Impedance Spectroscopy (EIS). Scanning Electron Microscopy (SEM) is used to monitor the effects of corrosion and machining surface texture of GMS. The SEM, surface roughness measurements and corrosion tests confirm that the surface is becoming rougher and corrosion behavior is worsening with the increase in current. The roughness of the surface can be correlated to thickness of recast layer (measured in SEM) that is increasing with the increase in current (heat input). © 2023

From the year 2016 to 2019, a total of 196 botanical drugs were registered for clinical trials, out of which 81 drugs were in phase II or III laid an environment for further trials and marketing of the drugs. Vasicine, a pyrroquinazoline alkaloidal compound found in some medicinal plants such as Justicia adhatoda and Sida cordifolia to name a few. Due to its broad range of health-promoting properties, the compound has piqued the attention of nutritionists and medicinal chemists. The compound’s recent pharmacological applications include antiviral activity against SARS-Co-V2, antimicrobial activity against E. aerogenes, S. epidermidis and P. aeruginosa, cytotoxic effect against lung adenocarcinoma and free radical scavenging activity, implying a potential role as an antioxidant. Vasicine was also discovered to have a possible anti-inflammatory property in carrageenan-induced inflammation, as well as neuroprotective efficacy in in vitro experiments on neuroblastoma cells by blocking cholinesterases in Alzheimer’s disease and improving memory and cognition. The integration of a multi-omics approach to elucidate the biosynthetic pathway and key regulatory enzymes laid the basis for metabolically engineering the entire pathway in microbial systems, as well as polyculture of microbes for robust biosynthesis strategies to overcome the limitations of traditional monoculture techniques for bioactive production. Genome editing with CRISPR Cas technologies plays a major role in the transformation of vasicine metabolite engineering to alter the process of biosynthesis and increase large-scale production in plants. © The Author(s) under exclusive licence to Society for Plant Research 2025.
