... 2007 Recommended by Hugo Van hamme This paper addresses the problem of blind speech dereverberation by inverse filtering of a room acoustic system. Since a speech signal can be modeled as being generated by ... s(n)isgivenasfol- lows. A speech signal is widely modeled as being generated by a nonstationary AR process [1]. In other words, the speech signal is the output of a spe...

... will cause fluorosis [2- 10]. Fluorosis caused by fluoride intoxication was first reported by Feil in 1930, and skeletal fluorosis was reported by Short in 1937 [7]. Normally, there are two sources ... the myeloradiculopathy caused by skeletal fluorosis was thought to be a result of compression of the spinal cord by osteophytes and vertebral osteosclerosis [7,23]. However, myelopath...
