This paper numerically studies two-finger grasping of deformable curve-like objects under frictional contacts. The action is like squeezing. Deformation is modeled by a degenerated version of the thin shell theory. Several differences from rigid body grasping are shown. First, under a squeeze, the friction cone at each finger contact rotates in a direction that depends on the deformable object’...

finger vein is one of the most fitting biometric for identifying individuals. in this paper a new method for finger vein recognition is proposed. first the veins are extracted from finger vein images by using entropy based thresholding. in finger vein images the veins are appeared as dark lines. the method extracts veins as well, but the images are noisy, that means in addition to the veins the...

finger reckoning is one of the five types of signification(dalala),which al – jahiz mentioned in his book, al–bayan wa al–tabyin . by this he meant a particular representing numbers by means of the outstretched or bent fingers and their various positions .finger reckoning can be traced in some prose and verse writings and traditional(hadith) sources; for example, in a recorded speech through wh...

Experienced neurosurgeons reduce hand tremble by placing their hand beside the operative field when performing microneurosurgery conventionally. Another solution to reduce hand tremble is an armrest. However, the reduction of hand tremble by using an armrest or finger-placing technique has not been rigorously measured in microneurosurgery. This study was performed to provide a quantitative asse...

The role of finger usage upon learning arithmetic has received increasing interest from various disciplines. In this opinion paper, we would like to emphasize that finger usage in calculation is not a unitary phenomenon. Rather, we propose two different types of finger usage: First, in many countries and independent of the number system in use, typically developing children use fingers as impor...

The Ministry of Health, Labour and Welfare of Japan estimates that there are nearly 22,000 deafblind people in Japan (2006). Communication is one of their largest barriers to independent living and participation. Deafblind people use many different communication media, depending on the age of onset of deafness and blindness and the available resources. “Yubi-Tenji” (Finger Braille) is one of th...

aim and background:   safe airway maintenance in patients under general anesthesia is the most important duty of anaesthesiologists. classic laryngeal mask airway (clma) is a supra-glottic device to achieve this aim. there are different insertion techniques for this device, but the best of them is unknown. methods and materials:   two hundred patients were included in this mono-blinded clinical...

We studied the dependence between voluntary motion of a finger and pressing forces produced by the tips of other fingers of the hand. Participants moved one of the fingers (task finger) of the right hand trying to follow a cyclic, ramp-like flexion-extension template at different frequencies. The other fingers (slave fingers) were restricted from moving; their flexion forces were recorded and a...

A cDNA encoding the 60 kDa subunit of mammalian splicing factor SF3a has been isolated. The deduced protein sequence reveals a 30% identity to the PRP9 splicing protein of the yeast S.cerevisiae. The highest homology is present in a zinc finger-like region in the C-terminal domain of both proteins. The PRP9 zinc finger-like motif has been replaced by the equivalent region of mammalian SF3a60. T...
