摘要： The present disclosure generally pertains to methods for the harvesting of biomass, in particular algae, from dilute aqueous suspension. In one embodiment, the method comprises the steps of: adjusting the pH of the dilute aqueous suspension to cause disruption of the algal cell walls and exposure of the hydrophobic tails of the algal lipid bilayer; adding at least one organic solvent to the dilute aqueous suspension; and mixing the dilute aqueous suspension. The method may also include the steps of: waiting for formation of an organic layer from the dilute aqueous suspension; and recovering the organic layer. The organic layer rises to the top of the dilute aqueous suspension, allowing for mechanical separation or decanting of the organic layer.

摘要： Performing power quality and synchrophasor analysis on a resampled signal. A first signal may be initially received which corresponds to a power system. The first signal may have a plurality of cycles and may have a frequency that varies over time. One or more parameters may be determined from the first signal. Based on the one or more parameters, the first signal may be resampled to produce an even angle signal. Various power quality measurements may be performed on the even angle signal. Similarly, further processing may be performed to perform synchrophasor measurements, e.g., to determine phasor, frequency, and/or rate of frequency change for the first signal. In some embodiments, the resampling processing elements (e.g., circuitry, programmable hardware elements, processors and memories, etc.) may be shared between the two analyses.
