As a special kind of soil erosion that severely deteriorates the qualities of soil in granite regions, collapsing gully is Anchors widely distributed in the tropical and subtropical areas of South China.In particular, collapsing-gully erosion produces a large amount of sediment deposited on the plough layer of alluvial fan farmland and causes incre
With the global commitment to achieving net zero carbon emissions by 2050, the importance of transitioning to clean and efficient energy sources has become increasingly crucial.On this note, grid resiliency is crucial for sustainable energy supply because it ensures a reliable and uninterrupted flow of electricity from renewable sources to consumer
Introduction Malaria is associated with high morbidity during pregnancy.Homozygous sickle cell pregnant women are even more exposed during complicated malaria.The objective of the study was to evaluate the maternal and fetal morbidity of homozygous sickle cell pregnant pregnant women with complicated malaria.Methods We conducted a retrospective cas
When Vacuum Pet Brush the misalignment angle is a large angle in the strapdown inertial navigation system (SINS), it is necessary to establish a nonlinear error model to estimate the error.Hence, an improved initial alignment method based on adaptive robust CKF algorithm is proposed in this paper.Firstly, based on the analysis results, SINS/GPS non
