Broadband wireless channels, where high data rates are transmitted, are extremely dispersive in nature. A fundamental challenge in the design of equalizers for the broadband case lies in reducing complexity. Broadband finite impulse response (FIR) beamformers employ a space-time antenna array which reduces the multipath delay spread to narrowband levels. The beamformers should additionally pres...

This essay argues that the semi-biographical film 8 Mile represents Eminem as being both racially distinctive and as possessing universal commercial appeal. 8 Mile accomplishes this paradoxical construction by portraying ‘‘Rabbit’’ as ‘‘white trash,’’ a discursively ‘‘dark’’ (white) object, and as an American mythological white subject. The film makes whiteness hyper-visible by subjecting it to...

In this paper the effect of whiteness attribute of white substrates on blackness property of black coated fabrics is investigated. To this aim, four cotton fabrics with different whiteness and tint attributes are used as white substrates. To prepare a set of black samples, various concentrations of four color pigments, i.e., red, green, blue and yellow, were mixed with the black one and applied...

The aim of this research was to describe the effects of altering the composition of a modified remineralizing agent (MRA) and the osmotic pressure on tooth color by using spectrophotometric analysis. One hundred and four (104) human premolars and molars were randomly divided into 2 groups of 52 specimens each. Group 1 was treated with the remineralizing agent MRA 55, (remineralizing agent 1), a...

Do online shopping advertorials for whitening skincare products in South Korea perpetuate a racial hierarchy wherein whiteness is maintained as an ideal beauty standard? If so, how this articulated and reinforced with words images? Whitening products, such tone-up creams sunscreens, have become increasingly prevalent the industry Korea. Adding level of nuance to earlier research, my research un...
