THREADLINE IN MELT SPINNING Distance From Spinneret (cm) Rate (Re1 Units) Molecular Status Fig 10 Interpretation of relative speed of length changes INTERPRETATION In spite of the fact that the experimental setups under 2 and 3 were not identical
In the paper the polarimetric current sensing solution used for measurements of high amplitude currents and short durations is presented This type of sensor does not introduce additional resistance and inductance into the circuit which is a desirable phenomenon in this type of measurement The magneto element is a fiber optic coil made of spun fiber optic The fiber in which the core is
In the presented work the potential of fiber-optic distributed acoustic sensing (DAS) for detection of small gas pipeline leaks (1%) is investigated Helical wrapping of the sensing fiber directly around the pipeline is used to increase the system sensitivity for detection of weak leak-induced vibrations DAS measurements are supplemented with reference accelerometer data to facilitate

2019/9/1In performing the experimental analysis the lateral vibration of the thin-walled composite beam was investigated and presented in the article The various lateral vibrations of the composite beam were caused artificially by the impact of an electro-magnet
Vibrations can generate noise and vibrations in buildings That is why it is necessary to generate a performance protocol to characterize the level of vibration affecting rail road infrastructure and sidewalks and nearby buildings to assess the influence of the train (speed type profile wheel ) rail (area of rolling) and route of step and finally define interim corrective measures
In order to investigate the effect of internal friction of umbilical cable on its vortex-induced vibration (VIV) responses the experimental study on VIV of bond umbilical cable (BUC) and un-bond umbilical cable (UBUC) was carried out in an experimental tank A current generator in the laboratory simulated the uniform current and the current velocities were observed in real time by using a
