This study simulates a n-i-p planar heterojunction for Na2SnBr6-based perovskite solar cells (PSCs), with Na2SnBr6 as the absorber layer, fluorine-doped tin oxide (FTO) as the substrate, and In2S3, IGZO, and SnS2 as electron transport layers (ETLs). Gold (Au) is used as the back contact. Na2SnBr6 was chosen for its low cost, non-toxicity, tunable band gap, excellent electrical properties, and stability. The SCAPS-1D simulator was employed to model the solar cell performance under AM 1.5 G light irradiation, focusing on factors like doping concentration, layer thickness, defect density, and interface defects across three device configurations: Device I (Au/Na2SnBr6/ In2S3/FTO/Al), Device II (Au/ Na2SnBr6/IGZO/FTO/Al), and Device III (Au/ Na2SnBr6/SnS2/FTO/Al). Device III achieved the highest PCE of 31.35%, FF of 85.95%, VOC of 0.7926 V, and JSC of 46.01 mA/cm22, making it a promising candidate for high-efficiency, lead-free perovskite solar cells. Devices I and II showed lower efficiencies of 27.47% and 30.98%, respectively. The study also analyzed quantum efficiency (QE), carrier dynamics, and recombination rates, highlighting the potential of Device III in advancing Na2SnBr6-based hybrid perovskite solar technologies for future solar energy applications. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

This paper presents a hysteresis current control for single-phase single-stage buck-boost grid-connected inverters. The inverter topology employs four switches that are operated with the grid frequency and two bidirectional switches that are operated with high switching frequency. Hence, unlike the existing single-stage inverter topologies, the switching losses are minimized. Moreover, this inverter configuration has the capability to operate both in buck and boost modes and utilizes only a single inductor. The proposed hysteresis current control eliminates the need for designing a dedicated modulation technique for this inverter topology. An active damping technique is utilized to cope with the resonance damping problem without employing additional sensor. The reference current needed in the hysteresis controller is produced using a proportional-resonant (PR) controller whose input is the grid current error. The use of PR controller guarantees zero steady-state error in the grid current. The validity and superiority of the proposed control method are confirmed by MATLAB/Simulink simulations under various operating conditions which include buck mode, boost mode, transition from boost mode to buck mode, reference current change and virtual resistor variation. The simulation results show that the proposed control method is able to transfer the desired current into grid successfully under all operating conditions. © 2023 IEEE.

High data rates over a single wavelength are required to meet and satisfy customer requirements for various new telecommunication applications. Therefore, encourage the full-service access network (FSAN) to choose a Time and Wavelength Division Multiplexing-Passive Optical Network (TWDM-PON) structure as a competitive candidate to upgrade the PON system data rate. IEEE and (ITU-T) announced single and multiple channels of the 25 G-EPON standards either by building a single line of the 50 Gb/s TDM-PON system or two lines of the 25 Gb/s TDM-PON. In addition, the Multi-Source Agreement (MSA) group adopted a single line of 25 GS-PON standards. Thus, deep research work is needed to evaluate these upgrades. The present investigation aims to configure and utilize the basic scheme of the 4×25 Gb/s TWDM-PON system for downstream signals to reach the 100 Gb/s PON capacity system. The progress of the method has been achievable due to the *** package. The software provides an excellent infrastructure to test and analyze the overall model performance. The wavelength plan from the C-band to the O-band is applied to mitigate chromatic dispersion (CD) and improve the received signals. The system distance reaches 23 km at a maximum of 128 end-users/wavelength. An opened eye diagram and acceptable BER and a Q factor values are obtained to investigate transmission quality. As a result, the outcomes of downstream signals are reasonable. Nevertheless, the optical reach is limited to 23 km at a 1:128 split ratio, so the split ratio of 1 to 256 users/ at a 20 km distance is our future work. © 2022 IEEE.

The rapid evolution of artificial intelligence (AI) and robotics technologies are bringing drastic changes to society and industry in these recent years. The impressive progress in facilitating smart manufacturing in this era of Industry 4.0 has made our lives much more convenient than ever before. Despite the greater reliability and stability of the robotic system, there are several challenges to overcome such as the restrictions of scenes, obstacles, and hardware specifications. Since a high precision positioning algorithm is of paramount importance in devising a mobile robot, the research in developing simultaneous localization and mapping has been garnered immerse attention especially from domains of the computer vision and autonomous robots. In this paper, a novel method is presented to significantly enhance the positioning precision of indoor unmanned guided vehicles. The approach involves several steps, including setting up hardware configurations and collecting relevant data by installing necessary devices and system packages within the robot operating system (ROS). Trilateration is employed to determine the relative position of the mobile robot using distance measurements. Coordinate transformation is then conducted to convert the collected input data of relative distances and orientations. Trajectory paths are obtained, and occupancy maps are constructed to estimate the resulting trajectory and generate a 2D grid map. Indoor localization and mapping are achieved using three drawstring displacement sensors along with orientation information from an Inertial Measurement Unit (IMU). The proposed method is extensively evaluated through experimentation on predefined navigation paths, and its performance is compared to state-of-the-art methods such as RealSense T265, Hector SLAM, and wheel odometry. The results show that the proposed method exhibits compelling performance in both mean error and occupancy map construction. Ultimately, the findings reported herein

The optimal dosage of insulin for diabetic patients using MLR and PCA introduces an advanced method for predicting optimal insulin doses for individuals with diabetes by leveraging machine learning techniques. Our approach integrates data preprocessing, feature extraction using Principal Component Analysis (PCA), and the development of multiple linear regression models. We evaluate our models using metrics like Mean Absolute Error (MAE) to demonstrate the limitations of traditional insulin dosage calculation methods. By utilizing historical patient data and real-time monitoring, our approach provides a more personalized and adaptable insulin therapy regimen. Our results indicate that combining PCA with multiple linear regression significantly improves the accuracy of insulin dosage recommendations, offering a promising solution for diabetes management. Additionally, conventional multi-linear regression models often overlook demographic and clinical similarities among patients, relying on generalized data that diminishes predictive accuracy. To address these challenges, By leveraging demographic and clinical similarities, our MLR model predicts optimal insulin dosages for diabetic patients, aiming to maintain effective glucose control and minimize hypoglycemia risk. Moreover, the model forecasts future blood glucose levels, offering proactive alerts to healthcare providers when glucose levels are anticipated to exceed the safe range of 80 to $180 \mathrm{mg} / \mathrm{dL}$. Experimental findings demonstrate that our MLR algorithm significantly supports healthcare professionals in prescribing precise insulin doses, ensuring sustained blood glucose levels within the desired range and thereby improving the overall management of diabetes.

Induction machines are widely used in industrial and household applications due to their efficiency in electromechanical energy conversion. However, broken rotor bars can significantly disrupt machine performance, typically manifesting as sideband harmonics near the fundamental frequency which can be utilized for fault detection. Nonetheless, frequency leakage can impede fault detection, concealing fault until substantial damage occurs. The proposed method, based on the rectified three-phase stator current (RTPSC), effectively reduces leakage frequency while maintaining the fault characteristic frequency (FCF) at its original amplitude. In addition, generate the fundamental harmonic at a frequency of 6 times. This approach aims to is to enhance diagnostic capabilities in the maintenance and monitoring of induction machines, improving operational efficiency and it also reduces the chance of catastrophic failures. The proposed methodology is tested on cases involving one, two, and three broken rotor bars, with the simulation results validated through experimental verification.
