摘要： The present disclosure describes various systems and methods for creating and presenting optimization visualizations that use normalized achievement variables. At least one illustrative method includes defining achievement functions that each operates on at least one of several achievement variables (each of the achievement variables representing a characteristic of a physical object or process), and transforming value ranges for at least two achievement variables into corresponding achievement level ranges by applying at least one of the achievement functions to the value ranges of the achievement variables (the achievement variables being a function of at least one common control variable). The method further includes combining the corresponding achievement level ranges to produce a combined achievement level range, and presenting a visual representation of the combined achievement level range to a user, enabling the user to select value ranges for the common control variable.

摘要： A rheometer instrument including a stationary frame, a sleeve suspended from the frame, a bob suspended within the sleeve, a cross-spring pivot suspending the bob from the stationary frame, and a force rebalance system for effecting the rotational displacement of the bob with a torque. The force rebalance system includes an arm attached to the movable portion of the cross-spring pivot, a rotational position sensor in close proximity to the arm for measuring the rotational displacement and angular frequency of the arm, and a force actuator positioned to apply force to the arm. The rheometer instrument may be used to calculate the rheological properties of Newtonian and non-Newtonian fluids.

摘要： Systems and methods for direct and indirect measurement of the density of a fluid which exhibits sag characteristics is disclosed. The sag measurement system includes a test container for holding a fluid mixture to be analyzed and a suction port on the test container. A pump is coupled to the suction port for circulating the fluid mixture from the test container through a circulation loop. A measurement device is coupled to the circulation loop and a return port directs the fluid mixture from the circulation loop back to the test container at substantially the same vertical location as the suction port. The fluid mixture flowing through the circulation loop passes through the measurement device before returning to the test container through the return port. The measurement device is operable to monitor the particle distribution of the fluid mixture as it changes due to gravity.
