The accurate extraction of railway tracks is crucial for the development of digital railway systems.However, traditional manual methods for track extraction are both time-consuming and tedious.At the same time, current deep learning neural networks often suffer from issues such as Footwear missed detections and false positives when it comes to iden
Langerhans cell histiocytosis (LCH) is a rare histiocytic tumour in adult.We report a case of LCH involving skull bones in a 35year old lady who presented with fever, headache and diabetes Snoring insipidus since two years.Radiological examination revealed osteolytic lesions in the parietal and occipital bones along with a solid, enhancing lesion i
Abstract Under strong earthquakes and extreme rainfall conditions, landslide clusters near rivers may block incoming water flows, forming cascade landslide dams.When subjected to extreme hydrological conditions, these cascade landslide dams can experience overtopping, which erodes and entrains material from the dam surface, compromising dam stabili
Under the alternating load, the chain of high-speed heavy-duty bucket hoist passes through hundreds of thousands or more shocks, and the final failure mode is mainly chain plate fatigue fracture.There is no report on this kind of Bridge Rectifier Diode chain fatigue tester at home and abroad.Through force analysis of chain plate, theoretical basis
P2.5 plug-in hybrid electric vehicles (P2.5-PHEVs) exhibit high transmission efficiencies and no power interruption in the shifting and mode switching process; thus, they have broad application prospects.The power transmission in a PHEV under pure electric startup does not entail the clutch, and the initial torque of the motor is often set under th
