Abstract: Tracking of health and resilience of physical equipment and related systems are disclosed. A system includes physical equipment and one or more processors. The physical equipment includes one or more assets. The one or more processors are configured to determine a resilience metric for the physical equipment. The resilience metric includes a real power component and a reactive power component based, at least in part, on an aggregation of real components and reactive components of adaptive capacities of the one or more assets. A cyber-physical system includes physical equipment, network equipment configured to enable the physical equipment to communicate over one or more networks, a physical anomaly detection system (ADS) configured to detect anomalies in operation of the physical equipment and provide a physical component of a cyber-physical metric, and a cyber ADS configured to detect anomalies in network communications over the one or more networks.

Abstract: A 1 GPa high-strength high-modulus aluminum-based light medium-entropy alloy and a preparation method thereof. An atomic expression of the designed medium-entropy alloy is AlxLiyMgzZnuCuv, subscripts representing the molar percentage of each corresponding alloy element, where x+y+z+u+v=100, x is 79.5-80.5, y is 1.5-2.5, z is 1.5-2.5, u is 13.5-14.5, and v is 1.5-2.5. The phase structure of the involved alloy is mainly based on a face-centered cubic (FCC) solid solution. The present invention obtains high performance aluminum alloy ingots through vacuum induction smelting and direct casting, and features low energy consumption, decreased cost, and simple operation in the preparation process, which cater to the high requirements on cost, strength and plasticity of light alloys applied in the high-end manufacturing industries such as aerospace and automobile electronics nowadays.
