Pitch, as a basic property of sounds and an important suprasegmental feature speech, exerts its effect on many linguistic aspects at different levels. The current study mainly focuses pragmatic meaning realized by phonetic forms, namely the accent placement tune. By observing pitch curves various renderings utterances from tool Praat analyzing these typical instances, it is concluded that great...

The special and unique advantages of explosive forming, has developed its use in different industries. Considering the important influence of improving the current explosive forming techniques on increasing the efficiency and control over the explosive forming procedure, the effects of air and water as the energy-conveying medium, and also their differences will be illustrated in this paper. He...

A non-intrusive method to measure the particle velocities in dilute-phase pneumatic conveying is described. The method is based on correlating signals, which are measured in two flow cross-sections. The cross-correlation function generated provides information about the time it takes for a particle to travel between the measurement planes. Knowing the inter-plane distance and the time delay, th...

The pressure drop and conveying stability caused by the bend significantly affect pneumatic process of stiff shotcrete, which is key to solving problem long-distance transportation. In this paper, effects different air velocities (32 m/s, 36 40 m/s), water-cement ratios (0.1, 0.2, 0.3), bending-diameter (4, 12, 20) on elbow R1 R2 are studied using response surface method. characterized variatio...
