The Silk Road

The Silk Road as an image is a relatively new one for Afghanistan. It appeals to both the pre-Islamic and the perceived Islamic past, thus offering an Islamic balance to previous identities linked to Bamiyan or to the Kushans. It also appeals to a broader and more international image, one that has been taken up by many other countries. This paper traces the rise of the image of the Silk Road and its use as a metaphor for ancient trade to encompass all contacts throughout Eurasia, prehistoric, ancient and modern, but also how the image has been adopted and expanded into many other areas: politics, tourism and academia. It is argued here that the origin and popularity of the term lies in late 20th century (and increasingly 21st century) politics rather than any reality of ancient trade. Its consequent validity as a metaphor in academic discussion is questioned

This paper presents a prototype linear response single exposure CMOS image sensor with two-stage lateral overflow integration trench capacitors (LOFITreCs) exhibiting over 120dB dynamic range with 11.4Me- full well capacity (FWC) and maximum signal-to-noise ratio (SNR) of 70dB. The measured SNR at all switching points were over 35dB thanks to the proposed two-stage LOFITreCs.

Non-regular sampling is a well-known method to avoid aliasing in digital images. However, the vast majority of single sensor cameras use regular organized color filter arrays (CFAs), that require an optical-lowpass filter (OLPF) and sophisticated demosaicing algorithms to suppress sampling errors. In this paper a variety of non-regular sampling patterns are evaluated, and a new universal demosaicing algorithm based on the frequency selective reconstruction is presented. By simulating such sensors it is shown that images acquired with non-regular CFAs and no OLPF can lead to a similar image quality compared to their filtered and regular sampled counterparts.

Black Actors

This text is a hermeneutic exercise about one of the paradigmatic works of Vinicius de Moraes, Orfeu da Conceição. This plays opens a partnership between the poet and the composer Antonio Carlos Jobim, which was fruitful and unique for Brazilian arts. Orfeu da Conceição is also paradigmatic because it is the first work to bring black actors to the stages of the Municipal Theater of Rio de Janeiro. Orfeu da Conceição led to one of the films that most contributed, positively or negatively, to the international image of Brazil in the second half of the 20th century, the award-winning Orpheus Negro, by Marcel Camus. The text will notice how many of the ideas and representations of the favela were already visible in the Brazilian popular repertoire prior to the composition of the play. The idea, in general, is to observe how, in addition to its poetic-musical quality, Orfeu da Conceição can also serve as a reflection on how we represent and see favelas in the urban context, both in 1956 and today.
