CFD on Parametric Analysis of Compression Ignition Engine by using Star CCM+
Abstract: Stringent emission from the conventional vehicles draws attention of automobile researches to develop engine either high fuel efficiency and low emission of NOx, CO and unburnt hydrocarbons. Hence, there by Homogeneous charge compression ignition came to the effect. Homogeneous charge compression ignition engine is the type of engine the well organised mixture of air and fuel ratio enters into the combustion chamber, and it is compressed up to auto-ignited temperature …

Study and Analysis of Robust DCT-2L-DWT-SVD Domain Based Digital Image Watermarking Techniques with Different Attacks Using MATLAB
Abstract: The proposed paper presents a combined technique of Discrete Cosine Transform (DCT), 2level Discrete Wavelet Transform (2L-DWT) and Singular Value Decomposition (SVD) based Digital Image Watermarking (DIW) with dissimilar attacks. In the initial stage, split the original (cover) image into four sub-bands LL,LH,HL,HH which are named according to the filter (high-pass or low-pass), select LL sub-band which is split in to four sub-bands - LL-LL ,LL-LH ,LL-HL, LL-HH using DWT …
