A blind signature scheme allows a user to obtain a signature on a given message without revealing any information about the message to the signer. The idea of blind signature was first introduced by Chaum at CRYPTO 1982. Blind signatures can be used in many applications, such as e-voting. Recently, Chakraborty and Mehta proposed a new blind signature scheme (Chakraborty-Mehta scheme) based on t...

This paper addresses the application of blind source separation (BSS) algorithms to the problem of blind equalization (BE) in a frequency selective multiuser environment. Compared with other algorithms that exploit the structural properties of the channel or data matrix, our approaches are insensitive to channel order estimation, robust to ill-conditioned channels and able to choose the \best" ...

Blind people need kinesthetic perception as feedback for providing information related to movement characteristics, such position in space and direction. The research purpose was determine the validity test-retest reliability of a test blind people. consists placing both feet correctly on 4 square targets (5 cm thick) placed right, left, front, back, at distance 100 from initial that is located...
