The family structures of ethnic minority groups in Britain are compared with those of the white population. Caribbeans’ low rates of marriage and high rates of single parenthood are characterised as adopting ‘modern individualism’. South Asians’ high rates of marriage are characterised as adhering to ‘old-fashioned values’. Even among Asians, Pakistanis and Bangladeshis stand out in terms of lo...

The edges and textures of a digital image may be destroyed by traditional denoising methods, which is a difficult problem in image denoising. In this paper, anisotropic diffusion algorithm based on Partial differential equation is studied. First, image denoising algorithms based on Perona-Malik model are studied. Second, a modified Perona-Malik model is proposed. In the porposed model, the grad...

Résumé M. A. Gomez — La question de Malik Sy et la fondation du Bundu. On a prétendu qu'en fondant l'État du Bundu (ca. 1698), Malik Sy s'inspirait consciemment du réformateur Nâsir al-Dîn, initiateur de jihâd en Mauritanie (la Shurbubba) et dans le nord-ouest du Sénégal (le mouvement tubenan) entre 1672-73 et 1677. Les sources concernant Malik Sy doivent être utilisées avec précaution, étant d...

We are developing a regularization technique for Perona–Malik diffusion equations that relies on multiresolution techniques. The main result of this paper is to show that the chosen discretization overcomes the ill-posedness of the nonlinear Perona–Malik model. The resulting algorithm is tested and the results are compared with pixel–based methods. keywords, phrases: Nonlinear diffusion, regula...

The Perona–Malik (PM) model, a classical anisotropic diffusion, can preserve edges while removing the noise. However, the defect of traditional PM model is tending to contain the staircase effect in the processed image. For this reason, a novel ramp preserving Perona–Malik (RPPM) model based on a new edge indicator is presented. In the RPPM model, the diffusion coefficient of the PM model is ad...
