    Effect of Position and Number of Hydroxyl Groups on the Oscillatory Behaviour of Isomers of Hydroxybenzoic Acid by Masood A. Nath, Nadeem B. Ganaie, R. P. Rastogi, G. M. Peerzada

    Published 2009-01-01
    “…In the present communication, the effect of isomers of hydroxybenzoic acids with respect to their oscillatory behaviour as organic substrates with inorganic bromate and manganese(II) ion as catalyst in aqueous acid medium (1.0 M H2SO4) have been studied. The number and the relative position of hydroxyl groups (-OH) in the aromatic ring is found to influence the oscillatory behaviour. …”

    Efficient wideband signals’ direction of arrival estimation method with unknown number of signals by Yaoping Zeng, Guangyue Lu

    Published 2016-11-01
    “…Using suitable coefficient m to weight and inverse the covariance matrix, the proposed method can obtain estimated noise subspace with unknown number of signals. Unlike conventional subspace estimation with heavy complex computations, the proposed method reduces the amount of computation by real matrix multiplication, and through only half of the total angular field-of-view. …”
