Digital enhancement of multispectral MSS data for maximum image visibility
A systematic approach to the enhancement of images has been developed. This approach exploits two principal features involved in the observation of images: the properties of human vision and the statistics of the images being observed. The rationale of the enhancement procedure is as follows: in the observation of some features of interest in an image, the range of objective luminance-chrominance values being displayed is generally limited and does not use the whole perceptual range of vision of the observer. The purpose of the enhancement technique is to expand and distort in a systematic way the grey scale values of each of the multispectral bands making up a color composite, to enhance the average visibility of the features being observed
Satellite land use acquisition and applications to hydrologic planning models
A developing operational procedure for use by the Corps of Engineers in the acquisition of land use information for hydrologic planning purposes was described. The operational conditions preclude the use of dedicated, interactive image processing facilities. Given the constraints, an approach to land use classification based on clustering seems promising and was explored in detail. The procedure is outlined and examples of application to two watersheds given

A note on parallel and pipeline computation of fast unitary transforms
The parallel and pipeline organization of fast unitary transform algorithms such as the Fast Fourier Transform are discussed. The efficiency is pointed out of a combined parallel-pipeline processor of a transform such as the Haar transform in which 2 to the n minus 1 power hardware butterflies generate a transform of order 2 to the n power every computation cycle

"Mastomania" Breastfeeding and the Circulation of Desire in Nineteenth-Century France
The concept of sexual pleasure while breastfeeding, still faintly scandalous in the twenty-first century, circulates in a variety of nineteenth-century French texts, from medical discourse to the fictional works of Balzac, Flaubert, and Zola. Although some medical authorities condemned sensual breastfeeding, or “mastomania,” as a vice, others used the promise of sexual pleasure to entice recalcitrant mothers to breastfeed. In representations of maternal breastfeeding found in both literary and medical texts, it is often the male gaze that constructs meaning. The reciprocal desire of mother and infant shifts to include a third person, the narrator-spectator, whose own desire for the breast creates a fantasy of maternal erotic response that is then condemned as a vice. This confusion of subject and object of desire raises complex questions about the motivations of the male authors of these texts. This article uses psychoanalytic theories of Freud, Klein, and Kristeva to argue that the erotic dimension of the breastfeeding couple is tolerated, and even celebrated, in nineteenth-century literature but only if the male gaze constructs and controls the mother’s desire
Boosting Asymmetric Charged DM via Thermalization
We consider a dark sector scenario with two dark matter species with opposite
dark charges and an asymmetric population comprising some fraction of
the dark matter abundance. A new mechanism for boosting dark matter is
introduced, arising from the large mass hierarchy between the two particles. In
the galaxy, the two species thermalize efficiently through dark Rutherford
scattering greatly boosting the lighter dark matter particle, far above the
virial and escape velocities in the galaxy, while the dark charge prevents it
from escaping. We study the consequences of this scenario for direct-detection
experiments, assuming a kinetic mixing between the dark photon and the photon.
If the charged dark sector makes up 5% of the total DM mass in our galaxy and
the mass ratio is between , we find that current and future
experiments may probe the boosted light dark matter for masses down to 100 keV,
in a hitherto unexplored parameter range.Comment: 25 pages, 8 figure
