Correct modeling of contact friction and correct incorporation of contact friction into calculations are important in diagnostic problems of deviated wells. Also, since wells are deviated, some sections of the rod string can be bent between two couplings in the middle of a ‘dogleg’ turn, which ...
The popular methods for evaluating the initial therapeutic effect (ITE) of noninvasive positive pressure ventilation (NPPV) can only roughly reflect the therapeutic outcome of a patient’s ventilation because they are subjective, invasive and time-delayed. In contrast, vibration response imaging (VRI...
The penalty coefficients were set to series values, and the F1 score was used to evaluate the classification ability of the model. The evaluation process is illustrated in Figure14. As illustrated, the diagnostic performance of the model gradually increased as the penalty coefficient increased for b...

To determine the details of the CO vibrational excitation, a 3/4 meter scanning monochromator 18 is used to record spontaneous infrared overtone emission from the side windows 16 of the cell. The CO first overtone IR band (2-3 μm) system is usually used as the diagnostic since the call ...
FIG. 5 is a flow chart showing the procedure of derivation of the mother wavelet ψ(t). In the abnormality diagnosing apparatus7, the evaluation waveform signal S is provided, and then the use range is selected as described above. After that, Hanning window processing is performed on the wa...

2) through a diagnostic link connector (DLC) 123 (shown in FIG. 3) for the purpose of obtaining real-time readings of the vehicle's speed, engine RPM and driveshaft RPM. For some vehicles, the vehicle interface subsystem reads calibration information from the vehicle controllers such as ...
Integrated preamplifiers are provided to match the D/A outputs to the power amplifier inputs. Patch paneling is provided to allow simple control laws to be implemented in analog for demonstration or diagnostic purposes. The AS/VIS hardware (vertical airmount/actuators and horizontal actuators) has...
