This study was conducted on 400 fetuses obtained from department of Obstetrics an...

basically the Watermarking process is use for hiding secret information for labeling digital picture. This paper presents a method of watermark embedding and extracting which is based on SVD (singular value decomposition) and Arnold Transform. The SVD is a linear algebra technique used for diagonalizable matrices and it transfer of convert most of the signal energy into very few singular values...

On the evening of Saturday 11 June 1842, Thomas Arnold, the educational reformer and Headmaster of Rugby school, strolled in the institutional gardens with his head boy, William Charles Lake. Thomas would subsequently dine with the Sixth Form boys; a customary act on the last day of term. His diary entry for that evening noted, ‘‘The day after to-morrow is my birthday, if I am permitted to see ...

We present algorithms to classify isolated hypersurface singularities over the real numbers according to the classification by V.I. Arnold (Arnold et al., 1985). This first part covers the splitting lemma and the simple singularities; a second and a third part will be devoted to the unimodal singularities up to corank 2. All algorithms are implemented in the Singular library realclassify.lib (M...
