In a mental rotation study, if the degree of the rotation angle of a visual stimulus becomes large, the response time for congruence judgment increases. Simultaneously, the cranial nerve becomes active. However, the relevance of the reaction response time to the same mental rotation angle degree conditions (e.g., the angle difference is 180o), and cranial nerve activity is unclear. Therefore, t...

Ultrasonic Guided Wave inspection of pipes has been extensively used in various industries such as oil, gas and petrochemical industries. The behavior of guided waves in straight pipes is well known but the presence of features like pipe bends, welds may distort the receiving signals. It is therefore a challenging task to study the behavior of guided waves through these features. However, the 3...

During the processing of nematic soft solids through process flow elements (pipe bends, elbows, etc.), constitutive behavior makes its presence felt via (with rheology driven effects increasing pressure drop) and final product microstructure. This paper explores microstructure configurations liquid crystals in a 90° pipe bends with different types wall anchoring. The governing equations Leslie–...

written for a particular gain. Then KGH = −1 so that a) when the amplitude of KGH is 1 or 0 dB and b) phase is 180o then we have the system just become unstable. Both the conditions have to be fulfilled. Hence, if we ask the question: How far is the system from instability ? We get two answers. The gain increment required at the frequency where phase is 180o and the phase increment required at ...

this paper presents a numerical study of local mass transfer coefficients in a 90° bend using the rng version of k–e model to include the influence of curvature on the turbulent transport. simulations were performed for flow through a 90°, 3-d bend for reynolds numbers of 13500, 90000, and 390000, schmidt numbers of 2.53 and 700 and curvature ratios of 1.5, 2, and 2.5. the differences between t...
