Abstract: A shape-morphing fin includes a fixed portion, a multistable portion, a coupling portion, and a vibration source. The multistable portion functions as a negative stiffness element. The multistable portion is selectively movable between a first position and a second position. The movement between first position and the second position is configured to remove the ice formation from the structure. The coupling portion couples the fixed portion to the multistable portion. The vibration source is configured to produce a resonant vibration to engage the movement of the multistable portion from the first position to the second position.

Abstract: A system can include one or more processors; memory; a data interface that receives data; a control interface that transmits control signals for control of pumps of a hydraulic fracturing operation; and one or more components that can include one or more of a modeling component that predicts pressure in a well fluidly coupled to at least one of the pumps, a pumping rate adjustment component that generates a pumping rate control signal for transmission via the control interface, a capacity component that estimates a real-time pumping capacity for each individual pump, and a control component that, for a target pumping rate for the pumps during the hydraulic fracturing operation, generates at least one of engine throttle and transmission gear settings for each of the individual pumps using an estimated real-time pumping capacity for each individual pump where the settings are transmissible via the control interface.

Abstract: A pre-mix burner apparatus includes a burner having a generally cylindrical burner surface, the burner having a generally circular burner inlet at one end of the burner, the burner inlet having an inlet diameter. A flow distribution member is arranged to distribute flow of fuel and air mixture into the burner. The flow distribution member includes a closed axially central portion configured to block flow of fuel and air mixture axially centrally into the burner. The flow distribution member includes a plurality of vanes extending radially outward from the closed axially central portion. The vanes are configured to generate a swirling flow of fuel and air mixture flowing past the vanes into the burner.
