Abstract: A radiation resistant high-entropy alloy is provided, having an FCC structure, defined by general formula of FeCoNiVMoTixCry, where 0.05?x?0.2, 0.05?y?0.3, x and y are molar ratios. The radiation resistant high-entropy alloy has excellent irradiation resistance and is subject to radiation hardening saturation at high temperature (600° C.) in a condition of a high dose (1-3×1016 ions/cm2) of helium ion irradiation. A lattice constant of the high-entropy alloy decreases abnormally after irradiation. The high-entropy alloy has a radiation resistance far higher than that of a conventional alloy and has an excellent plasticity and specific strength. In an as-cast condition and at room temperature, a tensile break strength of the high-entropy alloy is higher than 580 MPa, an engineering strain (a tensile elongation) of the high-entropy alloy is greater than 30%.

Abstract: Described herein are systems, methods, and non-transitory computer readable media for memory address encoding of multi-dimensional data in a manner that optimizes the storage and access of such data in linear data storage. The multi-dimensional data may be spatial-temporal data that includes two or more spatial dimensions and a time dimension. An improved memory architecture is provided that includes an address encoder that takes a multi-dimensional coordinate as input and produces a linear physical memory address. The address encoder encodes the multi-dimensional data such that two multi-dimensional coordinates close to one another in multi-dimensional space are likely to be stored in close proximity to one another in linear data storage. In this manner, the number of main memory accesses, and thus, overall memory access latency is reduced, particularly in connection with real-world applications in which the respective probabilities of moving along any given dimension are very close.

Abstract: The present disclosure relates to the technical field of dissimilar welding of Cu and a steel, and in particular to a welding wire for dissimilar welding of Cu and a steel and a preparation method thereof and a method for welding Cu and a steel. The present disclosure provides a welding wire for dissimilar welding of Cu and a steel, including, in percentages by mass, 5-25% of iron phase, less than 0.1% of inevitable impurities, and copper matrix. The welding wire of the present disclosure, containing two elements, i.e. copper and iron, is conducive to the mixing of the two phases—copper and iron—during the welding process, to form a mutual soluble region, thereby makes it possible to greatly increase the weldability, reduce the width of the weld, effectively overcome the tendency of cracks, and thus to ensure the formed weld with a high crack resistance.

Abstract: Described herein is a memory architecture that is configured to dynamically determine an address encoding to use to encode multi-dimensional data such as multi-coordinate data in a manner that provides a coordinate bias corresponding to a current memory access pattern. The address encoding may be dynamically generated in response to receiving a memory access request or may be selected from a set of preconfigured address encodings. The dynamically generated or selected address encoding may apply an interleaving technique to bit representations of coordinate values to obtain an encoded memory address. The interleaving technique may interleave a greater number of bits from the bit representation corresponding to the coordinate direction in which a coordinate bias is desired than from bit representations corresponding to other coordinate directions.

Abstract: The present invention provides a radiation resistant high-entropy alloy and a preparation method thereof. A general formula of the radiation resistant high-entropy alloy is TiZrHfVMoTaxNby, where 0.05?x?0.25, 0.05?y?0.5, and x and y are molar ratios. The preparation method of the radiation resistant high-entropy alloy comprises the following steps: mixing Ti, Zr, Hf, V, Mo, Ta, and Nb in order, and conducting vacuum levitation induction melting or vacuum arc melting, to obtain the radiation resistant high-entropy alloy. The high-entropy alloy in the present invention has an excellent irradiation resistance, and does not suffer radiation hardening damage under simulated helium ion irradiation. When helium bubbles are of same sizes as those of conventional alloy, the bubble density of the high-entropy alloy is far lower than that of the conventional alloy, and the lattice constant thereof decreases abnormally after irradiation.

Abstract: Described herein are systems, methods, and non-transitory computer readable media for performing an alignment between a first vehicle sensor and a second vehicle sensor. Two-dimensional (2D) data indicative of a scene within an environment being traversed by a vehicle is captured by the first vehicle sensor such as a camera or a collection of multiple cameras within a sensor assembly. A three-dimensional (3D) representation of the scene is constructed using the 2D data. 3D point cloud data also indicative of the scene is captured by the second vehicle sensor, which may be a LiDAR. A 3D point cloud representation of the scene is constructed based on the 3D point cloud data. A rigid transformation is determined between the 3D representation of the scene and the 3D point cloud representation of the scene and the alignment between the sensors is performed based at least in part on the determined rigid transformation.
