Abstract: A method of preventing standing waves in an installed gas turbine having a fan, having a fan speed, and a compressor, having a compressor speed, includes correcting the fan and compressor speeds for temperature and monitoring the corrected speeds to prevent them from converging, or becoming the same value. In addition, a computer implemented monitoring and adjusting program may monitor a position of an aircraft on an Acoustic Critical Turbo System Frequency (ACTSF) plot and make adjustments to avoid intercepting a surge line by changing the speed of the plane, one or both of the fan or compressor speeds or by changing altitude. An aircraft may form a standing wave when crossing or operating on a surge line of an ACTSF plot and this condition should be avoided which may require high data rate monitoring and control logic.

Abstract: A method of aspirating a liquid, includes: providing an aspirating probe which comprises a probe tip and a piston pump, wherein the probe tip and piston pump are in fluid communication; measuring an initial gas pressure in the tip of the aspirating probe prior to the liquid entering the liquid to be aspirated; moving the tip into the liquid, whereby a volume of gas is located between the top of the liquid and the piston of the piston pump; moving the piston of the piston pump a predetermined distance which corresponds to a selected volume of liquid to be aspirated; measuring the gas pressure in the volume of gas when the piston stops moving and the column of liquid pulled into the tip has equilibrated; determining the piston volume created by the movement of the piston; and determining the volume of liquid aspirated by the following formula: Vliquid aspirated=Vpiston volume?((Pinitial?Pfinal)*Volume/unit pressure), wherein Pinitial is initial gas pressure before the liquid enters the tip, Pfinal is fina

Abstract: A method for determining efficient synthesis of chemical compounds forming a chemical library, such as a library generated using combinatorial chemistry, is described and disclosed involving the generation of ordered sub-sets of compounds from such library in order to rank or choose which compounds to be synthesized based on reagents to be used.
