Abstract: The present disclosure discloses an automatic leveling control method for a four-leg support working platform, which comprises the steps: determining the mass center position of the working platform, determining the main bearing quadrant and distinguishing active legs from the driven leg; adjusting the driven leg to weak state, controlling all legs to synchronously actuate for leveling; calculating the limit compensating actuation length of the driven leg, and performing compensating actuation until accomplishing the leveling process. The method is advantageous in: high speed, high robustness, no repeated oscillation. The mass center always stays within the bearing zone of the active legs, thus completely eliminating capsizing risk of the working platform. The compensating actuation of the driven leg ensures there is no weak leg, and hence high attitude and load-bearing stability of the working platform is achieved.

Abstract: Embodiments of the present disclosure include techniques processing dynamically sparse neural networks as dense computations. A permutation is performed to translate an input tensor from a sparse format into a dense format. Once in a dense format, dense computation can be performed to generate output data that is also in the dense format. A reverse permutation may then be performed to translate the output data back into the sparse format. An analysis of the operator is performed prior to runtime to determine the one or more dimensions of the tensor expression associated with the operator that are permutation invariant. The permutation may permutate the input tensor across dimensions that are permutation invariant.

Abstract: A flexible piezoelectric thin film, and method of manufacture, has a polyvinyl alcohol (PVA)-glycine-PVA sandwich heterostructure. The thin film is manufactured by evaporating the solvent from a glycine-PVA mixture solution. The film automatically assembles into the PVA-glycine-PVA sandwich heterostructure as it is salted out. Strong hydrogen bonding between the oxygen atoms in glycine and hydroxyl groups on PVA chains are responsible for the nucleation and growth of the piezoelectric ?-glycine and alignment of the domain orientation.
