A computer implemented method and system exit to an assembler exit while executing an application on the computer. In a preferred embodiment, the invention includes a collar mountable to the pilings having an earth displacing structure formed thereon. The model can be designed to maximize at least liquidation rates andor profitability. The system also includes a power rail regulator configured to generate the DC rail voltage based on an input voltage and to regulate a magnitude of the DC rail voltage to vary between a minimum voltage magnitude and a maximum voltage magnitude and to regulate a variable magnitude of an output current. In some embodiments, a first analyte can be measured in a sample before the sample is separated into its components, and a second analyte can be measured in a component of the sample after separation. Additionally, the views may be stored, and new views may be propagated from the stored views.
