Abstract: A computing system generates a subset of design cases of candidate design cases. The system indexes, in the subset, data elements. The system generates a design of an experiment by, for each respective data element, determining a status indicating whether the respective data element corresponds to an uncontrolled factor or a controlled factor. When the status indicates the uncontrolled factor, the system determines if substituting a respective set of specified options of a respective candidate design case comprising the respective data element with a different set of specified options of the candidate design cases improves a criterion measure according to a design criterion. When the status indicates the controlled factor, the system determines if changing an assigned option of the respective data element improves the criterion measure. The system updates the criterion measure with an updated criterion measure according to a change of the subset based on generating the design.

Abstract: A water heater that includes a cylindrical storage tank and at least one heating element, is modeled using a one-dimensional model that includes: a vertical stack of disks representing the water volume in the cylindrical storage tank, and a stack of annular segments surrounding the vertical stack of disks. Various temperature measurements are determined via resistance calculations of the at least one heating element.

Abstract: An optical breakdown acoustic transducer can generate high-bandwidth, high amplitude acoustic waves via an optical breakdown process. The optical breakdown acoustic transducer can include a vessel having an interior cavity that is substantially filled with a fluid and a light source that emits light. The light can be directed through an optical element that focuses the light to at least one focal point located within the fluid, thereby causing optical breakdown and generation of an acoustic shockwave. The acoustic shockwave can then be coupled into a medium surrounding the optical breakdown acoustic transducer via an acoustic outlet coupled to the vessel. The acoustic output of the optical breakdown acoustic transducer can be tuned by adjusting the properties of the optical source and/or the shape of the cavity containing the fluid. The optical breakdown acoustic transducer can be used for imaging, sensing, communication, and mechanical disruption.
