    Abstract: In various aspects, a method of detecting surface irregularities on or in an internal surface of a cylinder for use in a piston-cylinder assembly is disclosed. The method can include (A) fixing a position of and an orientation of a first one of the cylinder and a piston; (B) configuring a positioner and a dynamometer to move a dynamometer and a second one of the cylinder and the piston along a common longitudinal axis, the dynamometer being mechanically coupled to the second one; (C) moving the second one relative to the first one along the common longitudinal axis between a first position and a second position, the piston being located inside the cylinder at the first position and at the second position; and (D) measuring, by the dynamometer, a frictional force between the piston and the cylinder during the movement.

    Abstract: A method of obtaining a numerical model is disclosed. The numerical model correlates estimated line width values to minimum pressure for gas bubble generation (MPGBG) values. An MPGBG value of each capillary tube in the reference group is measured for a liquid. A nanoparticle composition is deposited, under standard conditions, on substrate(s) from each respective reference capillary tube, to form nanoparticle lines. A line width of each of the nanoparticle lines deposited using each respective reference capillary tube is measured by a microscope apparatus. A numerical model that correlates estimated line width values to MPGBG values for the liquid is calculated.
