I. I NTRODUCTION According to the published literature‚ majority of the signal denoising methods in the Wavelet domain are based on soft and hard thresholding. The noisy signal is decomposed up to a suitable level‚ j‚ using Discrete Wavelet Transform (DWT) and based on noise variance Wavelet coefficients are thresholded √ at t = σ 2 log N (where t is threshold‚ σ is variance of noise and N is the numbers of samples) [1]‚ [2]. It is

Did Colonialism Change or “Transform” Africa “Forever”? From 1440 until 1833 the Atlantic slave trade was the principle reason for “normal” relationships between Europeans and Africans. This trade‚ along with other forms of commerce‚ allowed for a healthy‚ friendly and somewhat fair relationship between Africans and Europeans.

Cosine Transform Operates‚ and why is it so important in data compression in Multimedia applications [10] (c) A Simple Transform Encoding procedure maybe described by the following steps for a 2x2 block of monochrome pixels: 1. Take top left pixel as the base value for the block‚ pixel A. 2. Calculate three other transformed values by taking the difference between these (respective) pixels and pixel A‚ i.e. B-A‚ C-A‚ D-A. 3. Store the base pixel and the differences as the values of the transform. Given

Dead Sea Scroll The settlement of Qumran is one kilometer inland from the northwest shore of the Dead Sea. The scrolls were found in eleven caves nearby‚ between 125 meters (e.g.‚ Cave 4) and one kilometer (e.g.‚ Cave 1) away. None were found within the settlement‚ unless it originally encompassed the caves. In the winter of 1946–47‚ Palestinian Muhammed edh-Dhib and his cousin discovered the caves‚ and soon afterwards the scrolls. John C. Trever reconstructed the story of the scrolls from several

Haas and Hahn’s TED Talk‚ “How Painting Can Transform Communities” describes the effort and planning that is needed to create such astounding works of art.

To begin with‚ the community was not very well-behaved and did not set an example for others; not many people ventured out of
