Particle field holography data reduction by Fourier transform analysis

The size distribution of a particle field hologram is obtained with a Fourier transformation of the Fraunhofer diffraction pattern of the reconstructed hologram. Off-axis absorption holograms of particle fields with known characteristics were obtained and analyzed with a commercially available instrument. The mean particle size of the reconstructed hologram was measured with an error of + or - 5 percent, while the distribution broadening was estimated within + or - 15 percent. Small sections of a pulsed laser hologram of a synthetic fuel spray were analyzed with this method thus yielding a spatially resolved size distribution. The method yields fast and accurate automated analysis of particle field holograms

Bandwagonistas: rhetorical re-description, strategic choice and the politics of counter-insurgency

This paper seeks to explore how a particular narrative focused on populationcentric counterinsurgency shaped American strategy during the Autumn 2009 Presidential review on Afghanistan, examine the narrative’s genealogy and suggest weaknesses and inconsistencies that exist within it. More precisely our ambition is to show how through a process of ‘rhetorical redescription’ this narrative has come to dominate contemporary American strategic discourse. We argue that in order to promote and legitimate their case, a contemporary ‘COIN Lobby’ of influential warrior scholars, academics and commentators utilizes select historical interpretations of counterinsurgency and limits discussion of COIN to what they consider to be failures in implementation. As a result, it has become very difficult for other ways of conceptualizing the counterinsurgency problem to emerge into the policy debate
