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: Embodiments of the present disclosure include techniques for designing and generating a parallelization plan for a neural network so that workloads in the neural network may be split amongst multiple devices. Operators and tensors in the neural network are transformed into a set of functionally equivalent operators and tensors. These functionally equivalent operators and tensors are then scheduled to separate devices for execution.

Abstract: A stirring component includes a body arranged in an internal chamber at a side of a circular spline away from a flex spline of the harmonic transmission system. The body includes a coupling hole through which the body is coupled to and rotated with an input shaft of the harmonic transmission system, and at least one stirring recess arranged on a side of the body adjacent to the circular spline and has a varying depth in an axial direction to stir and push lubricant medium within the internal chamber towards the flex spline during rotation of the body. With the stirring component arranged within the internal chamber, the plate-shaped body can block the lubricant medium from moving further. Furthermore, the stirring component can stir and push the lubricant medium away from the body towards the flex spline.

Abstract: Submarines with air-charged cargo holds are provided. The pressurize hull of a traditional submarine's cargo hold is replaced by non-pressurized hull, which lowers costs for transporting dry cargo and solves strength and seal problems raised when providing large openings for hatches. The dive depth of the air-charged cargo submarines is not large, so the pressure and volume of the charged air in the cargo hold are limited. This allows problems associated with ensuring the safety of the crew and properly operating the submarine to be easily solved.

These animals and their eggs combined with crop plants will be varied food for humans in space. Water and nutrition left in the residues remaining after rearing the maggots can be recycled and used to fertilize crop plants. Rearing maggots, animals, and crop plants provides a self-sufficient food regenerative system that enables humans to live and work in space on long term missions independent of food from earth.
