IoT plays a major role in the automation of various industries and has become very important for making humans life to comfort zone. In poultry farms, the IoT is used for turning on and off the lights based on the intensity of the light and the fans based on the temperature in that environment. The water supply is very important for the proper growth of the chicks or hens. So, for the continuous supply of water, the nipple line system has been introduced to the poultry farm. Since the pressure of the water is reduced before going into the nipple line to avoid unnecessary wastage of the water like overflowing of the water or leakage of the water in the nipple, this allows the hens to drink water with great comfort. But this has the disadvantage of improper flow of water or flow of water with low pressure, which could cause the air to lock or block the flow of water. Improper monitoring of the water reduces the growth of the hens. To avoid this situation, poultry farm owners use labour to continuously monitor the water, but it is not efficient. The proposed research work sense the presence of water in the nipple line, and it could send the message to the farmer's phone with the help of the GSM module. For this process, the threshold distance is fixed;if the distance is greater than the threshold distance, it could send a message to the mobile number to which it linked. By this method, the water is monitored properly, the growth of the hen is increased and the cost of labour is also reduced. It is one of the cheapest and best methods to monitor the water in the nipple line. © 2024 IEEE.

Optimizing renewable energy harvesting in DC microgrid systems is achieved through the application of intelligent control strategies. By integrating solar photovoltaic (PV) systems, wind energy conversion systems (WECS), and battery storage within a hybrid renewable energy system (HRES), the aim is to boost energy efficiency and sustainability. The use of DC-DC converters is essential for stabilizing and synchronizing the variable DC outputs from solar and wind sources before they are combined into a common DC link. Various control techniques, including Fuzzy Logic Control (FLC) and Perturb and Observe (P&O) for Maximum Power Point Tracking (MPPT), are examined to ensure optimal power extraction from renewable sources. Simulation models developed in MATLAB/Simulink assess the system’s performance under different irradiance and wind velocity conditions, showcasing the effectiveness of intelligent control strategies in maximizing renewable energy utilization. The findings emphasize the significance of intelligent control in improving the efficiency and reliability of DC microgrid systems powered by renewable energy sources. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Journal of Optical Communications 2024年第4期45卷 737-740页

作者： Sharma, Himanshu Kumar, Arun Department of Computer Science & Engineering Jecrc University Jaipur India Department of Electrical & Electronics Engineering Jecrc University Jaipur India

With the exponential growth in information related applications and the continuous increase in voice over IP (VoIP) applications, the carriers are expanding their networks to provide improved services to their end users. In such cases, the synchronous optical network/synchronous digital hierarchy model is not suitable. In this work, we are going to investigate the electro optic switch with the help of a VB script to simulate the device for various parameters. Further, we will then scan the central electrode voltages and take account of the overlap integral taking place at the output port with the help of waveguide mode. The best switching for switches at different voltages so as to have negligible coupling loss for different input signals is investigated. We aim to evaluate the MZI switches with the Li-Tn channel profile wave guiding structure and confirm their performance as compared to the existing MZI switches. © 2022 Walter de Gruyter GmbH, Berlin/Boston.

Extraction and Energy Management of Solar Photovoltaic, Fuel Cell, and Battery Systems Using a Novel Multi Port Power Converter for DC Microgrid Applications

引用

IEEE Access 2025年 13卷 87418-87437页

作者： Nagesh, Guguloth Venkatesh Naik, M. Raveendhra, Dogga Bonthagorla, Praveen Kumar Mnnit Allahabad Department of Electrical Engineering Prayagraj211004 India Manipal Academy of Higher Education Department of Electrical and Electronics Engineering Karnataka Manipal576104 India

In DC microgrids, efficient power extraction and an effective energy management strategy (EMS) are crucial when integrating multiple power sources. This study presents a novel Four-Port Converter (FPC) configuration designed to extract power from photovoltaic (PV), battery, and fuel cell (FC) sources while employing an advanced EMS to manage energy distribution and meet the demand of DC loads. The proposed FPC features two unidirectional input ports to accommodate renewable energy sources (RESs) and one bidirectional port for integrating an energy storage device (ESD) within a unified configuration. This paper provides a detailed analysis of the converter's operation, exploring various operating modes for optimal power extraction and energy management from PV, battery, and FC sources. To achieve this, a closed-loop control strategy, along with the EMS, is implemented. Mathematical modeling and simulations demonstrate that this unified configuration ensures efficient, cost-effective, and uninterrupted power transfer among PV, FC, ESD, and the DC link. The design offers advantages such as a simplified structure, a lower component count, higher voltage gain, and reduced voltage stress on power semiconductors while effectively managing power flow among the sources. Both simulation and experimental results validate the feasibility of the proposed converter, highlighting its operational characteristics under different states and energy management modes. A laboratory prototype of the system was developed for a 60 V, 200 W load to assess the power extraction and energy management performance. The results confirm that the converter achieves an average efficiency of 93.86%. Additionally;a comparative analysis with existing four-port topologies and efficiency evaluations across various operating modes is presented. The findings demonstrate the superior performance of the proposed system in terms of higher voltage gain, lower switching losses, and reduced diode stress. © 2025 I

Colorectal cancer stands as the world’s second most prevalent cause of cancer-related fatalities. Traditional histopathological image analysis, the primary tool for pathologists to categorize colorectal cancer types, is hindered by its subjectivity and susceptibility to misdiagnosis. To address this challenge, a pioneering computer-aided diagnosis (CAD) approach utilizing supervised contrastive learning is proposed. It is the first application of supervised contrastive learning to colorectal cancer detection. This study explores the efficacy of different encoder architectures within the proposed supervised learning-based method, highlighting variations in performance based on the chosen encoder network. The proposed framework was evaluated on the Enteroscope Biopsy Histopathological H&E Image Dataset (EBHI), the first publicly available dataset for colorectal histopathology enteroscope biopsies. Experimental findings demonstrate the superiority of the proposed model over state-of-the-art methods, with classification accuracy, precision, recall, F1-score, and specificity for colorectal cancers achieving 97.3%, 98.87%, 98.32%, 98.59%, and 98.92% respectively. This model serves as a valuable supplementary diagnostic tool for pathologists, alleviating their workload and helping to formulate precise diagnoses and treatment plans. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

Rain-induced attenuation above 10 GHz can be severe at heavy rain rates resulting in deep fading, which can negatively impact the quality of receive signal level at the Earth station receiver. The dearth of direct measurement data in most of the tropical and equatorial climates has motivated the campaign for collection of rain attenuation data on slant paths in these regions. This is mainly due to a huge receiver margin required for such measurement, and which is very difficult to obtain by using a spectrum analyzer. The measurement results of rain rates and rain-induced attenuation in vertically polarized signals propagating at 10.982 GHz in a tropical Malaysian climate are presented in this study. The measured attenuation is compared with large-scale prediction models. As shown in the statistically-tested results, the Bryant model yields the best overall fit, while the Crane model yields the worst overall fit. The results show that the models have relatively good prediction capabilities in the Malaysian tropical climate;however, their prediction errors still need to be minimized. Therefore, in this study, a correction factor is proposed to enhance their predictions. © 2023 by Begell House.

There is an increased focus on energy savings in low-voltage DC (LVDC) loads for home appliances. The use of LVDC for the local distribution system enables easier integration with renewable sources. This work presents the control and management of power flow to DC loads in grid-tied photovoltaic (GPV) systems. This system provides bi-directional flow of power from the DC load to the AC grid, using a pulse width modulation (PWM) technique, employing a voltage source inverter between the DC nano grid and the AC main grid. The bidirectional converter controls the active power transferred in both directions while operating at unity power factor (UPF). The modified three-level hysteresis current controller and the voltage controller are designed as the inner loop and the outer loop, respectively, to control the bi-directional power flow. The corresponding grid voltages and currents are used to generate the reference currents. The proposed system has been validated through MATLAB/Simulink simulations and experimentation on a prototype system developed in the laboratory controlled by the dSPACE 1103 real-time digital controller board. The results show that a regulated DC voltage is obtained for dynamic changes of source and load like in a real-time environment. The control strategy with its validation shows the efficacy of the proposed system. © 2021 The Authors
