In theaters and the filmmaking industry, video streams, images, audio streams and scalar data are commonly used. In these fields, one of the most important magnitudes to be collected and controlled is the light intensity in different scene spots. So, it is extremely important to be able to deploy a network of light sensors which are usually integrated in a more general Wireless Multimedia Sensor Network (WMSN). If many light measurements have to be acquired, the simpler and cheaper the sensor, the more affordable the WMSN will be. In this paper we propose the use of a set of very cheap light sensors (photodiodes) and to spectrally and directionally correct their measurements using mathematical methods. A real testing of the proposed solution has been accomplished, obtaining quite accurate light measurements. Testing results are also presented throughout the paper.
The article explores the issue of the social uses of space, based on the example of the Zocalo or Great Square of Mexico during the period 1880 to 1885, when the Town Hall increased its pro hibitions on undertaking certain types of activ ities in the square and established fees for va rious functions, in keeping with the possibilities of remuneration they offered. Despite the desire to control the use of space and the official pro motion of civic ceremonies, several sources, par ticularly photographs, document the persisten ce of celebrating popular traditions, with the resulting uses and appropriations of public space in the promenade of the Zocalo.
