A universal material tester with two or more consecutively arranges test units has a test tool supporting carriage, which is provided with a removable partition that allows conversion of the test-unit installation socket from a multiple test unit holder into a single test-unit holder, or vice versa. An advantage of the tester is a possibility of expanding dynamic range of measurements by using two or more test units, which are installed in series at one setting and can be used in sequential tests without replacement but with different measurement ranges. This broadens the dynamic measurement ranges and allows revealing material properties otherwise unattainable. The test units may be combined with an imaging device installed in series with the test tools that engage the sample physically.

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.

Systems and methods for estimating a hardness of a rock mass during operation of an industrial machine. One system includes an electronic processor configured to receive a rock mass model and to receive live drilling data from the industrial machine. The electronic processor is also configured to update the rock mass model based on the live drilling data and to estimate a drilling index for a hole based on the updated rock mass model. After estimating a drilling index for the hole, the electronic processor is also configured to set a blasting parameter for the hole based on the estimated drilling index.

A method and an assembly for testing a shipping package are described. The assembly includes a scuff test sub-assembly, a belt burn test sub-assembly, and multiple conveyors positioned between to the sub-assemblies to convey a shipping package through the assembly. The scuff test sub-assembly includes an inclined plane and multiple objects which extend outward from the inclined plane. The belt burn test sub-assembly includes a plate that moves over a portion of one of the conveyors. The plate moves between a first position which obstructs movement of the shipping package but permits movement of the one of the conveyors relative to the shipping package and a second position where movement of the shipping package along the conveyor is not obstructed. At least two of the conveyors meet at a junction to change an orientation of the shipping package as the shipping package is conveyed across the junction.
