A common belief in quantization theory says that the quantization noise process resulting from uniform scalar quantization of a correlated discrete time process tends to be white in the limit of small distortion (\high resolution"). A rule of thumb for this property to hold is that the source samples have a \smooth" joint distribution. We give a precise statement of this property, and generaliz...

Abstract This article explores the role “whiteness” takes on in Mexico, where colonial, religious, and social heritages elevate it as an aesthetic ideal, simultaneously denying its underlying racism. It argues that skin tone is one of many physical nonphysical features together shape concept whiteness a context fluid, relational, intertwined categories class racial classifications.

Recognizing the monolithic role that neoliberalism has occupied in United States (US) second half of twentieth century (Harvey 2005) and building on notions racial formation projects posited by Omi Winant (2014), Jeong-eun Rhee (2013) conceptualizes what she calls “neoliberal project” (or “NRP”). While applies idea NRP to understandings Asian-American identity US, this article first seeks broad...

Focusing on the Muslim Other in Amsterdam, article explores how individual young Muslims embody their agency forms of micro-practices and socio-spatial relations. By highlighting spatio-corporeal aspects Muslims' presence within urban space, our ethnography foregrounds negotiate identities belonging everyday spaces encounter. Dealing with panoptical white Othering gaze, we describe a range “unr...

We propose a new multiresolution variational joint denoising/deblurring approach, involving a priori assumptions on the solution and knowledge of the imaging systems to account for effects due to acquisition noise (edge preservation, degradation noise modeling, bounded noise assumption and spectral control of noise level whiteness and stationarity). The techniques used are drawn from a variety ...

Bleaching teeth with 10% carbamide peroxide in a custom-fitted tray has been popular for more than 10 years. However, primary teeth are seldom considered for bleaching due to the need for compliance by the child and the natural whiteness of the primary teeth. This report describes an indication-teeth darkened from trauma-as well as the technique and outcome for bleaching discolored primary teeth.

this study investigates the influence of some chemical additives such as methanol, ethanol, sodium oleat, chloroform and sodium hexametaphosphate (shmp) on the dry fine grinding of calcite (x50= 33 µm) using a stirred media mill. the experiments were carried out by a batch operation, and the change in colour properties (ry, whiteness and yellowness) of calcite powder. the results showed that th...
