algorithm for pitch tracking [5] implemented in the VOICEBOX toolbox [6]. Using a frame length of 50ms, the pitch for each frame was calculated and placed in a vector to correspond to that frame. If the speech is unvoiced the corresponding marker in the pitch vector was set to zero. Figure 1 shows the variation in pitch for a

The staff (plural staves) is written as five horizontal parallel lines.Most of the notes of the music are placed on one of these lines or in a space in between lines. Extra ledger lines may be added to show a note that is too high or too low to be on the staff. Vertical bar lines divide the staff into short sections called measures or bars.A double bar line, either heavy or light, is used to

To find the total length of a flat spiral having outer end radius = 15.5 units, inner radius = 5 units the increase in radius per turn = 0.81 unit, the total No. of turns in the spiral is 7.5. This is an example of an Archimedean Spiral, otherwise known as an arithmetic spiral, where the arms get bigger by a constant amount for each turn.

The A Series combines high efficiency and reliability, low maintenance costs and a wide torque range. The right angle layout between INPUT and OUTPUT makes the A Series particularly compact. The gear set combination makes this right-angle product the most efficient and durable in Bonfiglioli's light- and medium-duty portfolio. The A Series can be completed with a wide range of electric motors

A spiral is a curve in the plane or in the space, which runs around a centre in a special way. Different spirals follow. Most of them are produced by formulas. You can make a spiral by two motions of a point: There is a uniform motion in a fixed direction and a motion in a circle with constant speed.
