5 days ago · The reliable operation of scroll compressors is crucial for the efficiency of rotating machinery and refrigeration systems. To address the need for efficient and accurate fault diagnosis in scroll compressor technology under varying operating states, diverse failure modes, and different operating conditions, a multi-branch convolutional neural network fault diagnosis method (SSG-Net) has been developed. This method is based on the Swin Transformer, the Global Attention Mechanism (GAM), and ...
1 day ago · Background Osteo-sarcopenia (OS) has become a global public health problem and a frontier research problem, as a combination of sarcopenia (SP) and osteoporosis (OP) diseases. The clinical performances include muscle weakness, systemic bone pain, standing difficulty, even falls and fractures, etc., which seriously affect the patient’s life and work. The pathological mechanism of the OS may be the abnormal metabolism which disrupts the equilibrium stability of the musculoskeletal system ...
1 day ago · Rotary swaging (RS) with mandrel was performed on aeroengine high-temperature alloy steel tubes at room temperature. Annealing experiments were conducted on both the non-RS and RS sections at various temperatures. The evolution of microstructure and mechanical properties was analyzed. Mechanical testing results revealed that RS resulted in a greater increase in yield strength compared to tensile strength, with a less pronounced recovery of yield strength enhancement after annealing ...
1 day ago · Working similarly as the Juno spacecraft orbiting Jupiter, three extended arms containing CrIII sensitizers (≡ solar panels) are designed to gather light. The energy is then transferred to the center of the system via alkyne molecular wires (≡ electric cables). Finally, the light collected by the central ErIII activator is re-emitted toward the observer (≡ telecommunication). View the article.
