Rice disease profoundly impacts crop growth and yield. Early disease detection is crucial for effective crop care and treatment. Automated extraction of diseased regions from rice leaves is essential for enhancing automated disease identification systems. In this study, we propose an innovative approach that enhances deep learning (DL) segmentation architecture (UNet) by incorporating dilated convolution, EfficientNetB4, and pixelwise logical AND operation. We focus on three prevalent rice diseases: bacterial leaf blight, brown spot, and leaf smut. Manual ground truth mask images are generated for each disease. A comparative analysis demonstrates the superior performance of the modified architectures over their unmodified counterparts. Notably, the modified UNet model stands out, achieving a mean loss of 0.3018 and a mean dice coefficient of 0.6785 which is a significant improvement compared to conventional UNet model.

This paper proposes a methodology to investigate the stability of transient current limiter (TCL) in distribution systems. The problem is formulated to justify the performance of 12-pulse and six-pulse converter and make an unstable system to stable condition. The proposed approach explicitly deals with stability as well as minimization of total harmonic distortion. Firstly, the conventional methods of Nichols Chart, Nyquist Plot and Bode Plot used to investigate the stability of the network using TCL. In the next stage, a modified TCL circuit is inserted in the network system to make the system completely stable. A comparative analysis using Fast Fourier Transform (FFT) is shown to make the system harmonic free using MATLAB simulation. The proposed design is found to be more efficient in making the system stable and harmonic free. [ABSTRACT FROM AUTHOR]

In this study, a simple, but effective method is presented for the limitation of the Y-yg transformers transient current. One of the main privileges of this method is its simple topology. It does not need any control circuit or measurement unit. The method is based on a three-phase thyristor bridge with a low resistance reactor. Since the number of thyristors is minimized, the voltage ripple, electrical losses and the malfunction probability owing to device failure are decreased considerably. The proposed method is simulated and validated by MATLAB simulation and conventional methods test results. It is shown that the proposed configuration is effective for the transient current limitation of Y-yg transformers. [ABSTRACT FROM AUTHOR]

This work describes a new technology to calculate the magnetic field emission of a High Frequency Series Resonant Inverter in a domestic induction heater by means of computational simulations. The calculation is performed assuming normal operation conditions required to measure the magnetic field by means of a triple loop antenna. This triple loop antenna, also known as a van Veen & Bergervoet antenna, is generally employed to test compliance with emission regulations in the frequency range of band A and band B i.e. 5-55 kHz.

Intensive use of induction heating (IH) technology can be seen in many areas such as industrial, domestic and medical applications. The evolution of high-frequency switches has facilitated the design of high-frequency inverters, the key element of induction heating technology. Controling output power in a high-frequency inverter for induction heating application is complex. However, the importance of IH technology is not widespread. Induction heating technology requires accurate output power and current control with appropriate dynamics. Several power control techniques have been discussed inrelation to designing high-frequency inverters for IH applications. This paper makes a comprehensive review of the various power control techniques regarding high-frequency inverters for modern IH applications (domestic & industrial). [ABSTRACT FROM AUTHOR]
