Abstract: Power transformers are exposed to electrical, thermal, and mechanical stresses during operation, leading to the degradation of insulation and the generation of dissolved gases. Utilities use IEEE and IEC standards use dissolved gas analysis (DGA) to detect incipient faults in oil-filled in-service transformers. Traditional gas ratio-based DGA methods, at times inconclusive diagnoses, limiting their effectiveness... More

Abstract: The rapid advancement of smart agriculture under the Industry 4.0 paradigm has accelerated the integration of digital and IoT technologies into modern farming systems, aiming to enhance productivity, optimize resource utilization, and promote environmental sustainability. Meanwhile, dragon fruit is a major export fruit of Vietnam, grown mostly in Binh Thuan, Long An, and Tien Giang... More

Abstract: The minimum variational free energy criterion comprises two criteria: the maximum semantic information criterion and the maximum information efficiency criterion, but it does not provide a method for balancing them. The Semantic Information G Theory, the author proposed in his early years, extends the rate-distortion function R(D) to the rate-fidelity function R(G), where R is... More

Abstract: Nowadays healthcare and clinical facilities have become an essential part of modern life. The triage system in hospitals and clinics plays a crucial role in the initial assessment of patients and emergency care. However, conventional triage processes that rely on human judgment often suffer from variability, limited resources, and the possibility of human error. In... More

Abstract: The paper presents an intelligent control approach for a Static Synchronous Compensator (STATCOM) using a Genetic Algorithm-optimized Proportional-Integral-Derivative (GA-PID) controller to mitigate voltage sags in power transmission systems. This shunt-connected device is part of the FACTS family and dynamically injects reactive power compensation through the Voltage Source Converter to hold stable voltage magnitudes. Conventional PID...

Abstract: This study investigates seasonal and diurnal variations of surface radio refractivity in a tropical region by comparing real-time derived values from a low-cost automated Global System for Mobile Communication Signal Strength and Radio Climatological (GSM-RC) monitoring device with those modeled by ITU-R P.453-13. The GSM-RC device, installed at 3-m height, provided real-time, in-situ measurements of... More
