Mass Flowmeter Using a Multi-sensor Chip
We report here a novel two-mode mass flowmeter that can be operated in either thermal or differential pressure mode. By combining these two complementary operating principles, the performance can be improved significantly. This flowmeter is based on a multi-sensor chip that includes a 1-D array of shear stress, pressure and temperature sensors. The multi-sensor chip can also be employed in many...
متن کاملHarmonic Oscillator with Fluctuating Mass
We generalize the previously considered cases of a harmonic oscillator subject to a random force (Brownian motion), or having random frequency, or random damping. We consider here a random mass which corresponds to an oscillator where the particles of the surrounding medium adhere to the oscillator for some (random) time after collision, thereby changing the oscillator mass. Such a model is app...
متن کاملMediastinal mass caused by syphilitic aortitis.
A 47 year old man presented with hoarseness and chest pain found to be due to proliferative syphilitic aortitis. The case is unusual as the syphilitic aortitis caused a mediastinal mass without affecting the lumen of the aorta.
متن کاملPenile Mass Caused by Mycobacterium tuberculosis
Tuberculosis of the penis is rare. The clinical features of penile tuberculosis are usually manifested as ulceration or scars. However, the authors encountered a case of penile tuberculosis that presented as a mass. A painless nodule at the base of the penis was noted in a 63-year-old male patient. Surgical excision was recommended, and pathologic finding revealed granulomatous inflammation in ...
متن کاملHarmonic analysis-based diagnostics of noflow pulsation in vortex and swirl flowmeter
The vortex/swirl flowmeters are meant to measure the flowrate based on the measurement of the flow frequency. Due to the frequency-dependent computation of the flowrate, noflow pulsation causes a false positive, i.e., it indicates certain amount of flowrate when actually there is no flow. This happens when for example, the valves of the flow pipe are closed causing no flow, but some pumps are w...
