Software for controlling the VO2system100can be stored on and executed by the controller140, and can include setup, calibration, and measurement options. The flow chart in FIG. 2 shows the measurement sequence300used for control, data acquisition, and calculation. To take a measurement, the sof...
the current being supplied to the heater for the oxygen sensor element, the ON/OFF signal to a heater control transistor, a voltage input timing, a heater current input timing, the timing of a calculation of duty ratio, the timing of a transistor...
The data were from PET examinations on 749 patients, and included (a) the time chart log of the radiosynthesizer, which includes the time-radioactivity curves of the radio-detectors and gas chromatograms; (b) AIF recorded by the functional image calculation software; (c) record of Capnometer...
assumptions. In the context of dissolved oxygen in water, the van’t Hoff equation can be used to estimate the change in solubility of oxygen as the temperature changes. The equation allows the calculation of a scaling factor that represents the relative change in solubility between two ...
Calculation of power input for adsorbers regeneration was based on referential parameters obtained from available technical documentation of real adsorbers with a similar size [62], assuming that the same means of regeneration were adopted for both referential and model adsorbers (electric heating of ...
The result of this calculation suggests that the volume fraction of O2 inside the evapo- rated water is very low, close to zero, even though no pre-degassing was involved, and similar results hold for water evaporated at high temperatures under atmospheric pressure conditions. However, it should...
