A method of seating a fluid reservoir in a housing of a fluid infusion device is presented here. The method is performed prior to establishing an outgoing fluid flow path from the fluid reservoir. The method begins by detecting insertion of the fluid reservoir into the housing of the fluid infusion device. In response to detecting the insertion, the method determines whether the fluid reservoir is in need of depressurization. When the fluid reservoir is in need of depressurization, the drive motor assembly of the fluid infusion device is rewound to depressurize the fluid reservoir. After depressurizing the fluid reservoir, an equalization state for the fluid reservoir is achieved. After achieving the equilibrium state, the drive motor assembly is advanced to obtain an initial seated state for the fluid reservoir.

The invention relates to a method an computer system for using extrapolation analysis to express an approximate self-consistent solution or a change in a self-consistent solution based on a change in the value of one or more external parameters, said self-consistent solution being used in a model of a system having at least two probes or electrodes, which model is based on an electronic structure calculation comprising a self-consistent determination of an effective one-electron potential energy function and / or an effective one-electron Hamiltonian. The method of the invention comprises the steps of: determining a first self-consistent solution to a selected function for a first value of a first external parameter by use of self-consistent loop calculation; determining a second self-consistent solution to the selected function for a second value of the first selected external parameter by use of self-consistent loop calculation, said second value of the first selected external parameter being different to the first value of the first selected external parameter; and expressing an approximate self-consistent solution or a change in the self-consistent solution for the selected function for at least one selected value of the first selected external parameter by use of extrapolation based on at least the determined first and second self-consistent solutions and the first and second values of the first selected external parameter.

An HCCI engine is operated by controlling a plurality of engine operating parameters in accordance with a calibration data set representing equilibrium set-points of engine operation characterized by combustion phasing that is relatively least sensitive to cylinder charge temperature deviations.

A method for reducing the fluorosurfactant content of a stable fluorosurfactant-containing aqueous fluoropolymer dispersion containing iron ions comprising: exchanging the fluoropolymer dispersion with a strongly basic anion contacting the resin to reduce the content of the fluorosurfactant to a predetermined level, the anion exchange resin is in the hydroxide form, separating the dispersion from the anion exchange resin, and adding an effective amount of Chelating agents are used to complex iron ions to prevent scum formation, said chelating agents having an equilibrium constant of at least 1018 when complexing iron.
