Transmitting supplementary data by steganography, new functions can be added to communications systems without changing conventional data format. Based on this concept, several applications have been proposed for enhancing the speech quality of telephony communications. These applications secretly transmit side information along with speech data itself for enhancing the performance of signal pr...

The main objective of this work is to develop a recursive algorithm for identification in the state-space of linear stochastic discrete multivariable non-stationary system; a computational process called MOESP_AOKI_VAR is proposed and implemented to achieve this. The proposed algorithm is based on the subspace methods: Multivariable Output-Error State Space (MOESP), used for computational model...

The oribatid mite genus Galumna (Oribatida, Galumnidae) is recorded for the first time in Nepal. A new species, Galumna tetraporosa sp. n., is described from soil of secondary mixed broadleaved forest. It is most similar morphologically to G. tokyoensis Aoki, 1966 and G. valida Aoki, 1994, however, it differs from both by the absence of interlamellar setae and the presence of two pairs of notog...

The “MGP analysis” created by Dr. J. Aoki in 1983 and the “100 oribatid species” system proposed by Aoki in 1995, both for using oribatid communities as bioindicators, are described herein and compared to some other bioindicator protocols. By using the term “naturalness”, Aoki proposed to explain human impact on a gradient of several environments ranging from urban boulevard trees to intact for...
