    Abstract: An apparatus includes a holder to support an indenter relative to a sample of material, a depth sensor, and a controller to execute instructions for performing operations. The operations include controlling the holder to apply a first force on the sample with the indenter and determining a first depth of the indenter based on first data generated by the depth sensor, controlling the holder to move the indenter from the first depth to a predetermined depth greater than the first depth, after the indenter is moved to the predetermined depth, controlling the holder to apply the first force on the sample with the indenter and determining a second depth of the indenter based on second data generated by the depth sensor, and determining a value indicative of hardness of the sample based on a difference between the first depth and the second depth.

    Abstract: Methods, systems, and apparatus for performing convolutional computations using an optical system. In some aspects computations for a neural network are performed in a digital domain using electronic circuitry, the neural network including a convolutional layer. Input data for the convolutional layer of the neural network is obtained, and a convolution or correlation computation on the input data in an analog domain using an optical correlator module is performed to generate an optical correlator module output. Based on the optical correlator module output, data is processed through additional layers of the neural network in the digital domain using the electronic circuitry.

    Abstract: A method for producing an experimental output satisfying an objective includes conducting an experimental execution process including applying a selection criterion to select an approach to determining a set of parameters for a set of experiments, and determining a first set of parameters for a first experiment according to the selected approach based on one or more of (i) a predicted relationship between a set of parameters and a characteristic of a corresponding experimental output, (ii) the measured characteristic of a second experimental output from a second experiment executed according to a second set of parameters, (iii) the objective, and (iv) a parameter selection rule. Conducting an experimental execution process includes controlling execution of the first set of experiments according to the first set of parameters, where execution of each first experiment includes conducting the experiment according to the first set of parameters to produce a first experimental output; and measuring the characteristic of the first experimental output. The method includes determining whether the objective is satisfied by the experimental execution process, and, when the objective is not satisfied by the experimental execution process, conducting a subsequent experimental execution process.

    Abstract: An apparatus includes a holder to support an indenter relative to a sample, a depth sensor, and a controller. The operations include applying a first force on the sample with the indenter and determining a first depth of the indenter based on data generated by the sensor, moving the indenter from the first depth to a greater predetermined depth, then applying the first force on the sample with the indenter and determining a second depth of the indenter based on second data generated by the sensor, and determining a value indicative of hardness of the sample based on a difference between the first depth and the second depth. The apparatuses described can use a single scale for hardness that enables hardness values for different materials to be compared to one another.
