摘要： An innovative method to automatically place sensors and stimuli-sensitive active actuators to neutralize the effects of structural faults and design a smart fault-resilient system is described. To the best of our knowledge, the proposed framework is the first systematic integration of thermally activated shape memory polymer actuators with a sensor distribution framework targeted to bring a damaged structural system to its native state. The framework does not explicitly model the material constitutive model and hence can be applied to linear and nonlinear material behaviors. The approach enables the design of resilient smart structures that can be additively manufactured. The framework computes a matrix of relative importance for different sensor positions and uses that to optimally place actuators to reconfigure the system in presence of faults.

摘要： A method includes receiving a representation of a near-net shape including a 3D part and a support volume. The method also includes calculating a measure of inaccessibility of the support volume by at least one subtractive tool assembly. The method also includes calculating a measure of change in a physical quantity of interest with respect to a change in the near-net shape. The method also includes constructing a physics-aware inaccessibility measure based at least partially upon the measure of inaccessibility, the measure of change, or both. The method also includes creating a plan to remove at least a portion of the support volume using the at least one subtractive tool assembly based at least partially upon the physics-aware inaccessibility measure.

摘要： A method systematically developing reduced-order (e.g., upscaled or coarse-grained, lumped- or distributed-parameter) multi-physics models for simulating additive manufacturing may include: describing governing equations of an additive manufacturing process; refactoring the governing equations into (1) constitutive laws with unknown coefficients and (2) conservation laws; discretizing the governing equations; and training the unknown coefficients of the constitutive laws with simulated data and/or experimental data relating to the additive manufacturing process where the conservation laws are enforced in the training regardless of a granularity of the constitutive laws, thereby yielding a reduced-order set of governing equations.

摘要： A nondestructive method for detecting damage in parts and/or characterizing effective material properties may include: exposing a material to one or more nondestructive stimuli; measuring a response of the material to the stimuli; selecting at least one of a specific length scale or a specific time scale; and analyzing the measurement of the response with a scale-aware single- or multi-physics model to identify anomalies in the measurements as compared to an expected response of the material to the stimuli, wherein the scale-aware single- or multi-physics model is based on the at least one of the specific length scale or the specific time scale.

摘要： Methods and systems useful for artificial intelligence-assisted generation of viable hypotheses may have (1) an ability to rapidly enumerate and test a diverse set of mathematically sound and parsimonious physical hypotheses, starting from a few basic assumptions on the embedding spacetime topology; (2) a distinction between non-negotiable mathematical truism (e.g., conservation laws or symmetries), that are directly implied by properties of spacetime, and phenomenological relations (e.g., constitutive laws), whose characterization relies indisputably on empirical observation, justifying targeted use of data-driven methods (e.g., machine learning (ML) or polynomial regression); and (3) a “simple-first” strategy (following Occam’s razor) to search for new hypotheses by incrementally introducing latent variables that are expected to exist based on topological foundations of physics.

摘要： A systematic framework to design active resilient structures that simultaneously optimizes the characteristics of the system to yield an optimal solution in terms of robustness to external disturbance, uncertainty in structural properties, and structural faults. The proposed approach will yield a preferred or optimal solution as opposed to designing individual components of the complete system. The framework provides the preferred or optimal location and precision of heterogeneous sensors and stimuli-sensitive active actuators and the control law guiding these active actuators to control the resilient structure. The framework provides a systematic approach to designing active resilient structures by choosing the location of smart actuators/sensors to mitigate the unwanted effects of uncertain structural properties. The framework is the first systematic integration of thermally activated shape memory polymer actuators and their guiding law with a sensor distribution framework targeted to bring a damaged/disturbed structural system to its native state.

摘要： Quantum field-programmable analog arrays (FPAAs) may be useful in solving differential equations. For example, a quantum FPAA may comprise: an array of computational analog blocks (CABs) configured to perform a mathematical operation; and an interconnection network connecting the CABs, the interconnection network comprising communication paths and switches. Said quantum FPAAs may be useful in integrated chips, computing systems, and related methods.

摘要： A method includes receiving a representation of an initial design domain. The method also includes iteratively generating intermediate part designs by redistributing material within the initial design domain. The intermediate part designs each include a 3D part and a support volume. The method also includes calculating a measure of inaccessibility of the support volume of each intermediate part design by at least one subtractive tool assembly. At least one of the intermediate part designs is generated based at least partially upon the measure of inaccessibility of a previous one of the intermediate part designs.
