EO/IR sensors enhance border security, part two

This chapter analyzes tactical intelligence, following a division by posture: offensive and mobile, and defensive or localized. There was an increase in the use of vanguards among the Greeks after the fourth century BC and among the Romans in the first. Cavalry widely used in this role. The role of reconnaissance in border security is then evaluated. It is noted that the speculatores who accompanied the legions left the field for the office sometime in the first century AD. Greek military intelligence never became professionalized, and did not ponder the sophistication of the prototypical organizations fielded by the tyrants of Cyprus and Sicily in the fourth century. Professionalism and unit identification in intelligence came neither to the poleis nor the kingdoms of Classical or Hellenistic Greece, and came finally to the Romans at least a century after they had pervaded the legions.

Ir Reflectography

AbstractInfrared (IR) reflectography has been used for many years for the detection of underdrawings on panel paintings. Advances in the fields of IR sensors and optics have impelled the wide spread use of IR reflectography by several recognized Art Museums and specialized laboratories around the World. The transparency or opacity of a painting is the result of a complex combination of the optical properties of the painting pigments and the underdrawing material, as well as the type of illumination source and the sensor characteristics. For this reason, recent researches have been directed towards the study of multispectral approaches that could provide simultaneous and complementary information of an artwork. The present work relies on non−simultaneous multispectral inspection using a set of detectors covering from the ultraviolet to the terahertz spectra. It is observed that underdrawings contrast increases with wavelength up to 1700 nm and, then, gradually decreases. In addition, it is shown that IR thermography, i.e., temperature maps or thermograms, could be used simultaneously as an alternative technique for the detection of underdrawings besides the detection of subsurface defects.

This article explores an increasingly significant trend in crime and mobility control that has received scant criminological attention: border externalization, specifically scrutinizing land border security-building by international actors in West Africa. Going beyond the usual focus on migration in border studies, it develops a criminologically grounded theorization of the border as a political technology of crime control and its relationship to the state. This is done by arguing that borders, theorized as ‘penal transplants’ embodying specific (western) visions of state, political power, social control/order and territoriality, are transformed and often distorted when performed in ‘heterarchical’ contexts in the global South. Further, empirically based concepts from ‘the periphery’ are suggested to enrich border criminology, broadening its geographical scope and spatial awareness.
