The rapid development of urbanization has led to a continuous rise in number elevators. This elevator failures from time time. At present, although there are some studies on fault diagnosis, they more or less limited by the lack data make research superficial. For such complex special equipment as elevator, it is difficult obtain reliable and sufficient train diagnosis model. To address this issue, paper first establishes numerical model vertical vibration for elevators with three degrees freedom. obtained motion equations then used constraints acquire simulated through PINNs. Next, proposed e-RGCN employed diagnosis. Finally, experimental validation shows that accuracy participation digital twins exceeds 90%, reaches 96.61%, significantly higher than other comparative models.

Small-scale agriculture is important. However, there are still limitations regarding the implementation of technologies in small-scale due to high costs accompanying them. Therefore, it essential seek viable and low-cost solutions since insertion agriculture, especially irrigated guarantees sustainable expansion production capacity. The present work applied Internet Things concept an automated irrigation system powered by photovoltaic panels. materials used prototype consisted Arduino Uno R3, ESP8266 development board, a soil moisture sensor, current voltage flow humidity temperature sensor. was designed take readings send them Adafruit platform IO. Furthermore, programmed perform remote control, enabling this be activated from distant points through platform. medium proved efficient for monitoring control system. This indicates that possible use small systems.

The complexity of operating power systems requires the development methods capable assisting in system monitoring. Voltage Stability Margin or Load (LM) represents an index that informs how much system's load level can increase without causing a case instability. LM is determined using voltage stability criteria, but low-frequency modes arise with increasing and cause This article proposes method based on Recurrent Neural Networks (RNNs) for monitoring LM. Furthermore, metaheuristic called Greylag Goose Optimization applied to choose buses whose measurements will be RNN inputs.
