FASA Fire Airborne Spectral Analysis of natural disasters

At present the authors are developing the system FASA, an airborne combination of a Fourier Transform Spectrometer and an imaging system. The aim is to provide a system that is usable to investigate and monitor emissions from natural disasters such as wild fires and from volcanoes. Besides temperatures and (burned) areas FASA will also provide concentration profiles of the gaseous combustion products. These data are needed to improve the knowledge of the effects of such emissions on the global ecosystem. The paper presents a description of the instrumentation, the data evaluation procedure and shows first results of retrieval calculations based on simulated spectra

OPTICAL DESIGN AND BREADBOARD OF THE RAMAN SPECTROMETER FOR MMX

This paper reports the laboratory confirmation of an optical design for a 0.2 numerical aperture confocal miniaturized, ruggedized Raman visible light spectroscope (RAX) to be borne by an autonomous rover landed on the martian moon, Phobos

Inverse problems of Hamel-type.

The formulation and discussion of the simplest (fixed) end point direct problem of the calculus of Variation is a necessary preliminary to attack on the inverse problems considered in Chapters II and III of this thesis. Since the plane problem is already comprehensively treated in the literature, only enough of its theory is developed here to render intelligible to the reader the inverse problems studied in the sequel

Time dependence of the Compton current and energy deposition from scattered gamma rays. [1 to 6 MeV]

The time dependence of the energy deposition and radial Compton current produced by scattered gamma rays must be known to make better use of the geomagnetic component of the radioflash signal of a nuclear explosion for diagnostic evaluation of the source. To provide a data base for empirical analytic fits to describe this dependence, a series of Monte Carlo calculations of monoenergetic gamma-ray sources in a homogeneous, isotropic air medium were performed, and the results were fitted with relatively simple and readily usable relations. The results are summarized by graphs and formulas. 8 figures

"I wanna do b-boy moves, but I wanna be known as a b-girl": Learning to break as an identity construction process

How do women and girls learn within the male-dominated hip-hop culture? This article takes a close look at this question based upon a qualitative study on education processes in breakdancing. The gender theory of Judith Butler in terms of gender identity construction in repetitive performance acts is first introduced, and then analogies to learning and dancing in hip-hop culture are drawn. Handling the loud differences between male and female is an issue that is strongly present for B-girls and that becomes a topic in learning to be negotiated on the path to finding a personal style. Illustrated by examples, different strategies are outlined and then used as a basis for developing questions about and approaches to educational practice. (DIPF/Orig.
