Image denoising is a compromise between the removal of the largest possible amount of noise and the preservation of signal integrity and image resolution. To address this issue, a new hybrid approach is proposed by fusing dual band spectral subtraction and wavelet packet based thresholding method. The dual band spectral subtraction method (SS) is used for(More)
WiMAX at 4.9GHz has been identified by the ITU as important in achieving harmonised spectrum for advanced public protection and disaster relief. The band is currently used for this purpose in the US for disaster relief. The most recent WiMAX standard (802.16e) supports broadband applications to mobile terminals and laptops.

A colorimetric method for the analysis of escitalopram oxalate in pure form and in tablets has been developed based on the formation of chloroform soluble ion associates with bromocresol green acidic dye. The extract of ion associates exhibited absorption maxima at 417 nm obeying Beer's law in the range of 2-10 µg/ml. The method is simple, precise and(More)
