Reliability of gas turbine power plant is related to the blade normal operation. In this paper, a new on-line condition monitoring method has been presented to evaluate two important factors affecting the turbine blades that are the tip clearance and tip deformation. A K band’s microwave sensor has been simulated and optimized in CST Microwave Studio software. Scattering parameters of the near...

The present study focuses on geometric features of workspace and joint-space paths of three-dimensional reaching movements. Twelve subjects repeatedly performed a three-segment, triangular-shaped movement pattern in an approximately 60 degrees tilted horizontal plane. Task variables elicited movement patterns that varied in position, rotational direction and speed. Trunk, arm, hand and finger-t...

Tactile sensors and electrotactile stimulators can provide important links between humans and virtual environments, through the sensation of touch. Soft materials, such as low modulus silicones, are attractive as platforms and support matrices for arrays sensors and actuators that laminate directly onto the fingertips. Analytic models for the mechanics of three dimensional, form-fitting finger ...

finger patterns and ridge-counts in a random sample of iranian muslims consisting of 100 males and 100 females are described. the most common finger patterns found were loops, having a frequency of 54.4% u.l., 3.4% r.l. in males and 51.2% u.l. and 4.8% r.l in females. the frequencies of arches and whorls in both sexes were 4% and 38.5% respectively. bimanual and sex differences were indistinct....

Tactile displays are used to convey small-scale pressure and shape information to the finger tip. Our device designs include a 1x10 pin display using shape-memory alloy actuators and a 6x6 pin display using inexpensive commercially available servomotor-gearhead packages. Our human factors studies suggest that bandwidths of about 30 Hz are required for free exploratory motions with pin-based dis...

the aim of the this work was to determine the finger patterns, finger ridge count (frc), total finger ridge count (tfrc), and asymmetry of finger ridge count (afrc) of an iranian girl (aged 13 years) affected with congenital cutis laxa (ccl).the fingerprints of the first phalanx of both hands were taken by using the standard method (stamp ink). the fingerprints were classified according to the ...
