Robust speech enhancement using amplitude spectral estimator by Abdul Rahman, Abdul Wahab, Chong, Tan Eng, Abut, Huseyin

“…This paper focuses on a class of speech enhancement systems using the amplitude spectral estimates of noisy speech and noise to drive a Wiener filter to suppress simultaneously the ensemble of degradations picked up by microphones. A simple stereo microphone set with left and right channels can be used to provide enough separation that unwanted signals can be reduced significantly to yield acceptable quality speech signal for handsfree telephony application in a vehicular environment. …”

The structural and functional studies of the non-stereospecific α-haloacid dehalogenase (DehE) from rhizobium sp. RC1 by Abdul Hamid, Azzmer Azzar, Wong , Ee Lin, Joyce-Tan, Kwee Hong, Shamsir, Mohd Shahir, Tengku Abdul Hamid, Tengku Haziyamin, Huyop, Fahrul Zaman

“…DehE consis ts of only helices motif and depicted active site showed that the binding orientiations of both D- and L-2-chlor opropionic acid by using substrate-docking analysis shared similar key binding residues among non-stereo specific α -haloacid dehalogenases. Twelve residues lining the active site has identified and some of them were verified using site-directed mutagenesis tests. …”
