A method of controlling a pumping stage of a fracturing fleet at a wellsite with a set of diesel pumps and at least one electric pump to smooth the flowrate transition to an operational setpoint with a higher flowrate. An optimization process communicatively connected to the plurality of pumping units can iterate an interim setpoint with a transfer function model to each pumping unit. The transfer function model can generate a smooth flowrate transition by decreasing the flowrate of at least one pump unit while increasing the flowrate to the remaining pump units.

Method to control hydraulic fracturing spread with electric pumps

A method comprises generating, via a pulse generator, a first pressure pulse in a fluid in a pipe and detecting, via a transducer, a first reflected pressure pulse based on the first pressure pulse, wherein the first pressure pulse is reflected by a pipe feature to generate the first reflected pressure pulse. The method comprises generating, with the pulse generator, a second pressure pulse at a later time relative to generating the first pressure pulse, wherein timing of generating of the second pressure pulse is such that the second pressure pulse is superposed with the first reflected pressure pulse such that an amplitude of the second pressure pulse is greater than an amplitude of the first pressure pulse. The method comprises detecting, via the transducer, a second reflected pressure pulse based on the second pressure pulse, and detecting a pipe feature based on the second reflected pressure pulse.

Detection of pipe features with pressure pulses

There is provided a method of assessing fibrosis in a tissue sample. The method includes: obtaining a stained image of a stained tissue sample, the stained tissue sample being stained in relation to collagen therein; producing a plurality of different types of collagen images based on the stained image, the plurality of different types of collagen images corresponding to a plurality of different types of collagen, respectively; determining a plurality of different types of collagen parameters based on the plurality of different types of collagen images using a deep neural network; and determining a degree of fibrosis in the stained tissue sample based on the plurality of different types of collagen parameters. The plurality of different types of collagen comprises portal collagen, fibrillary collagen and septal collagen. The different types of collagen images are produced by determining if the collagen satisfies a predetermined size condition or a predetermined distance condition with respect to a boundary of the portal tracts and central veins.
